Technology transforms diabetes
'The Palmer Injector', Glasgow, Scotland, 1955-1965
Technology can transform the experience of diseases: a life-threatening condition can be turned into a manageable 'chronic' - long-term - condition. This is the case for many with type 1 diabetes, whose health depends on insulin-injecting devices. Patients with type 1 diabetes are unable to produce the essential hormone insulin, and without it the body cannot turn sugar from food into energy needed to live.
Injecting insulin
Banting and Best discovered insulin in 1922. Before then, prospects for diabetic patients were bleak. Some managed their condition through strict diets. Banting and Best showed patients could take animal insulin to replace their missing hormone. The first insulin injection was given to 14-year-old Leonard Thompson at Toronto General Hospital, Canada, on 23 January 1922. Regular insulin injections meant patients like Leonard could live normal healthy lives, but ones reliant on devices.
Managing diabetes at home
Managing diabetes back then was difficult. Insulin must be delivered straight into the bloodstream, and in the early days the only way to do this was with a hypodermic needle and syringe. Patients initially went to doctors for injections, but the need for several injections a day made this impractical. Patients were given equipment so they could manage their condition at home without doctors.
Insulin injections could be extremely painful and inconvenient. To stop needles getting blunt (making injections more painful), pumice stones were used to sharpen them. Patients also used sterilising equipment to clean needles after each injection.
New devices helped people with diabetes inject insulin. In 1955 a diabetic called Charles Palmer invented the Palmer injector to make self-administered injections easier. In 1985 insulin injection pens were introduced. These are discreet and convenient, and they 'click' when the right dose is reached.
As well as giving themselves injections, patients monitored their sugar levels so they knew how much insulin to take. Initially only urine glucose tests were available. Testing urine could be messy and inconvenient. In the 1980s new blood glucose monitors let patients test their blood for sugar. Most people with diabetes preferred these.
Alternatives to injections
An alternative to injections was not developed until the 1960s. The first insulin pump was the AutoSyringe. It was pioneered by American doctor Arnold Kadish and known as the 'big blue brick'. The first model was so large it had to be worn like a backpack. Instead of an injection, pumps deliver frequent small doses of insulin directly into the abdomen. By the 1990s the devices were small and portable. Some diabetics, particularly children, prefer pumps because they do not require painful injections. They also give greater control over the amount and frequency of insulin taken.
Experts at managing illness
Diabetic patients are often called 'expert patients' because they manage their illness largely by themselves. Being in control of their condition means they need less support from medical practitioners.
Scientists are still searching for new ways for patients to take insulin. Inhalers, patches and pills are all alternatives to injections.

Alaska Tidal Datum Portal
Unambiguous vertical datums in the coastal environment are critical to the evaluation of natural hazard vulnerability in support of local and regional planning. Appropriate tidal data must be considered in the siting, design, construction, and operations of development projects to ensure protection of human life, property, and the coastal environment.
Alaska Tidal Datum Reference Table
Help update the Tidal Datum Portal, improve the National Spatial Reference System, and facilitate public access to Alaska benchmarks by collecting GPS data and making a contribution to the shared Online Positioning User Service (OPUS) database.
- About the Alaska Tidal Datum Portal
- Frequently Asked Questions (FAQ)
- What is a datum and why do I need to care about tidal datums?
A vertical datum is a reference surface from which we can measure elevations on the earth's surface. The North American Vertical Datum of 1988 (NAVD88) is currently the official geodetic vertical datum for the United States. A NAVD88 elevation is an orthometric height, which means a height above the geoid (an equipotential gravitational reference surface that approximates an idealized global sea surface). Orthometric heights may be determined by combining a measured height above the ellipsoid surface (a simplified, smooth 3D model of the earth's shape) with a model of the geoid. NAVD88 elevations are obtained in this manner by combining the vertical component of the NAD83 ellipsoid, which can be measured using a GPS receiver or though differential leveling, with GEOID12A (the best available geoid model).
Consider the following example:
You own a home on the coast that has a foundation elevation of 2 m, referenced to NAVD88
One day you hear a report from the National Weather Service that a large storm system will be delivering a surge to your area with a forecast water level elevation of approximately 1 m above MSL (Mean Sea Level)
What does this mean to you?
Note that your home elevation and the forecast surge have not been reported using the same datum. To compare the forecasted water elevation to your foundation elevation you will need to know how your local MSL relates to NAVD88 (the red value in the image above). Your local MSL datum may be higher (as shown) or lower than the NAVD88 datum depending on your location along the coast.
If the local MSL in your community is 1.5 m above NAVD88 then the forecasted surge elevation of 1 m above MSL is 2.5 m referenced to NAVD88. Since your house is only at 2 m referenced to NAVD88 you will need to take action in this example.
Tidal datums are specific to the location of measurement and they may become considerably different with distance from the original tide station, particularly in shallow water areas. Therefore, a tidal datum applies only to the immediate area for which it was determined.
- What types of tidal datums exist?
A complete list of definitions for tidal datums maintained by NOAA is available at the NOAA Tides & Currents website. Tidal datums typically refer to a 19-year National Tidal Datum Epoch (currently 1983-2001), a period of time that encompasses full variation in the path of the moon relative to the sun. A Modified 5-Year Epoch is used in certain regions with anomalous sea level changes. Approximately 12% of Alaska's local tidal datums are calculated with a Modified 5-Year Epoch (currently 2002-2006).
The datums most commonly used in Alaska are listed below:
Datum Name Abbreviation Definition Mean Higher High Water MHHW
Average of the higher high water height of each tidal day observed over a 19-year National Tidal Datum Epoch or a Modified 5-Year Epoch.
For stations with shorter series (1-3 months is common in Alaska), comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the Modified or National Tidal Datum Epoch.
Mean High Water MHW
Average of all the high water heights observed over a 19-year National Tidal Datum Epoch or a Modified 5-Year Epoch.
For stations with shorter series (1-3 months is common in Alaska), comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the Modified or National Tidal Datum Epoch.
Mean Sea Level MSL
The arithmetic mean of hourly heights observed over a 19-year National Tidal Datum Epoch or a Modified 5-Year Epoch.
Shorter series (1-3 months is common in Alaska) are specified in the name; e.g. monthly mean sea level and yearly mean sea level.
Mean Lower Low Water MLLW
Average of the lower low water height of each tidal day observed over a 19-year National Tidal Datum Epoch or a Modified 5-Year Epoch.
For stations with shorter series (1-3 months is common in Alaska), comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the Modified or National Tidal Datum Epoch.
- I thought that NAVD88 elevations are referenced to Mean Sea Level, aren't they the same thing?
Elevations referenced to NAVD88 (North American Vertical Datum of 1988) should never be used as Mean Sea Level.
This is one of the most common mistakes made by someone who is new to working with elevations in the coastal zone and you are not alone - confusion about how local MSL relates to published geodetic elevations has existed as long as we have had national geodetic datums.
Do you live in Rimouski?
If you answered no, you need to pay attention to your tidal datums.
NAVD88 "MSL" ≠ Local MSL
Position of Local MSL relative to NAVD88(GEOID12A) in meters
The first standardized vertical datum used in the United States was the National Geodetic Vertical Datum of 1929 (NGVD29), previously named the "Sea Level Datum of 1929." NGVD29 utilized the 19-year water level records from a network of 26 tide gauge stations in the United States and Canada to establish a fixed MSL (Mean Sea Level) surface to which all geodetic benchmarks in the nation could be adjusted. In 1988 a more accurate vertical datum (NAVD88) was adopted as the national standard. NAVD88 is referenced to the Mean Sea Level at one tide station located at Father Point in Rimouski, Quebec.
On an idealized earth without ocean mixing or atmospheric variation the surface of the ocean would coincide with an equipotential surface in the gravity field (the geoid) and orthometric heights would correspond to the height above mean sea level. However, there are two primary reasons that the orthometric NAVD88 elevations do NOT correspond to local mean sea level:
- Our map of the earth's gravity field is not complete so we need to use a model of the geoid (GEOID12A for example). Geoid models are a good approximation of the true geoid but they are not perfect, particularly in many parts of Alaska.
- Oceanographic and atmospheric effects are constantly changing the ocean surface and causing it to deviate from where we would expect it to be on an idealized earth. Local mean sea level is not driven by the earth's gravity field alone.
- What are some causes of variation in my local tidal datums?
You may notice that tidal datums in your area of interest might vary slightly in publications and from what you calculate. This variation can usually be attributed to one of the following factors:
Different Tidal Benchmark
For some tide stations, published geodetic elevations may be available for more than one tidal benchmark. If tidal datums are connected to the geodetic datum via a different benchmark there may be minor differences in the calculated adjustment due to allowable vertical measurement errors.
Orthometric Height Computation
NAVD88 elevations are orthometric heights that are calculated by combining a geoid height (height above the surface of equal gravitational potential) with the measured height above the reference ellipsoid at a given point of interest. As geoid models are improved, the orthometric height of a tidal benchmark that is used to relate the benchmark to the tidal datum will change.
Re-establishment of Tide Station
Reactivation of a tidal station, particularly for a prolonged period of time, may result in an improved measurement of the water levels in a particular area. For example, many tidal datums in Alaska are currently based on <1 month of water level measurements. A reoccupation for a duration of 3 months or more can greatly improve the accuracy of the calibrated tidal datums.
Tidal Epoch
A tidal epoch is a specific 19-year period adopted by the National Ocean Service as the official time segment over which tide observations are taken and reduced to obtain mean values for tidal datums. The current National Tidal Datum Epoch is 1983-2001 and the Modified 5-year Epoch is 2002-2006. Tidal datums calculated in different epochs may vary, particularly in regions with positive or negative trends in sea level change.
- I don't see a location listed in the calculator; where are the rest of the tidal datums?
A tidal datum is only applicable to the area immediately surrounding the same tide station. Tidal datums are referenced to local water levels and should not be applied to coastal areas of differing oceanographic characteristics. Likewise, the elevation relationship between a tidal and geodetic datum is valid only at the location of the datum measurements. Due to variations in tidal range, bathymetry, topography, the geoid, and vertical land subsidence or uplift, the extrapolation of this unique relationship beyond the location of measurement requires careful corrections and mathematical interpolation, and is not always possible.
Important: If your area of interest is not listed in the tidal datum calculator, you cannot use the values from another nearby location for the reasons described above.
Until the network of tidal datum measurements is expanded in Alaska, the ability to link offshore measurements to onshore measurements is limited. The following options are available to obtain a surrogate tidal datum estimate:
Install a temporary tide gauge
A temporary tide gauge, installed by a government agency, university or private consultant, may be used to monitor water levels for a period of several days to several months. The measured values can be tied to the local geodetic datum using traditional differential leveling techniques or a static GPS survey occupation of at least three benchmarks.
Measure the geodetic elevation of an identifiable foreshore feature
Appropriate foreshore features will vary by shore type and tidal range. Examples include the wrack line on a beach or a biological band, such as barnacles, on a rocky coastline corresponding to the approximate mean higher high water. This measurement may be accomplished using traditional differential leveling techniques or with the use of a static GPS survey occupation.
Use a modeled value
Hydrodynamic circulation numerical models are capable of simulating typical water level conditions over large computational domains. These models are limited by the quality of bathymetric data, particularly in coastal areas, but are capable of producing an estimate of tidal datums in areas where no direct measurements are available. Refined gravimetric geoid models may also be used to approximate local MSL values. The USGG2012 geoid model, when used with the GRS80 ellipsoid, will produce a reasonably good approximation of local MSL values in most of Alaska.
- What is VDatum?
VDatum is a software tool maintained by NOAA. It allows users to easily transform elevation values between a range of tidal and geodetic (both orthometric and ellipsoidal) datums. VDatum is a valuable tool in the creation of seamless topographic-bathymetric elevation grids that are necessary for coastal mapping applications, including storm surge, tsunami and sea level change vulnerability and ecosystem management.
VDatum uses a continuous sea surface grid (the TSS, Topography of Sea Surface) to make transformations between tidal and geodetic datums. This method is preferable to methods that rely on direct local transformations alone because it allows for interpolation across areas between known tidal datums. Because VDatum requires this TSS, a robust network of established measured tidal values, geodetic measurements and tide model predictions is a prerequisite to the availability of the VDatum software in any region.
VDatum is currently available for all coastal states in the contiguous United States (including the Great Lakes) as well as in Puerto Rico and the Virgin Islands.
For additional information on VDatum and its status in Alaska, visit the NOAA VDatum website.

Kid Fest
The popular Kid Fest will return to the Carl Parker Center on the campus of Lamar State College-Port Arthur on Saturday, June 25, from 10 a.m. to 4 p.m.
Clear Channel Radio and Valero Port Arthur Refinery have once again teamed up to bring hundreds of kids the opportunity to enjoy activities such as fishing, dancing, face painting, arts and crafts and high-flying acrobatic dunking basketball action.
"The event was phenomenal last year," said Barbara Phillips, public affairs manager for Valero. "We had over 2,000 people attend the event and lots of exhibitors and great entertainment. The community seemed to enjoy it and we got lots of support from other community and industry sponsors."
Two very popular attractions from last year's event that are returning include KidFish and Team AcroDunk.
KidFish is a traveling non-profit organization based in Little River, which is located between Austin and Temple, dedicated to facilitating and educating a new generation of outdoor enthusiasts.
KidFish brings a portable fishing pond indoors that allows youngsters to fish. According to their Web site, KidFish hopes to instill in children a deep appreciation for the sport of fishing as well as awareness and respect for the conservation of the environment and its natural resources. Fishing is a lifelong pursuit that is as much about spending quality time on the water with family and friends as it is about catching lots of fish. The outreach programs give children and families the opportunity to experience a tradition by introducing them to the balance of nature and the concept of stewardship.
If you see people flying people through the air — don't be alarmed. It's the nationally touring Team AcroDunk. The group of basketball athletes performs high-flying, gravity defying, acrobatic slam-dunk action. Team AcroDunk recruits children into the sport of thinking and challenges them to approach training their brain with the same intensity, passion and focus that star athletes train their bodies are the premier providers of acro-dunking entertainment and inspiration. The team has been seen on shows like "America's Got Talent," "Ripley's Believe It Or Not" and featured on ESPN's Sportcenter Top 10.
The fun-filled day will also focus on education, safety, environmental practice plus visit with members of local agencies.
"One of Valero's goals and commitments is to support community events, especially when it benefits children, so this is a perfect chance for us to do something for the children in our neighborhood," added Phillips.
Phillips also stressed the importance of others helping out with the second annual Kid Fest including Allen Samuels Chrysler, Dodge and Jeep, Christus Hospital St. Mary's, Port Arthur Industry Group, Port Arthur Steam Energy, Motiva Enterprises, Veolia ES Technical Solutions, Academy, Chevron Phillips, Synergy Federal Credit Union, Air Products, New Eagle Cleaners, Port Arthur Federal Credit Union, Michael Fuljenz Universal Coin & Bullion, Conn's, Lamar State College, Total, Port Arthur EDC and Little Caesars Pizza.
While supplies last, free tickets are available at the Valero Corner Store located on 4530 Twin City Highway in Groves, Academy (8453 Memorial Blvd., Port Arthur), Allen Samuels (8181 Memorial Blvd. Port Arthur) and Conn's (7855 Memorial Blvd., Port Arthur). While in Beaumont, swing by the Clear Channel studios at 2885 Interstate 10 East.
For more information, view any of the Clear Channel Web sites at bigdog106.com, klvi.com, cool925.com and kykr.com or call (409) 896-5555.The Carl Park Center is located 1800 Lakeshore Drive in Port Arthur.

The Role of Agents in Self-Publishing by Chris Eboch from Write Like a Pro! A Free Online Writing Workshop. Peek: "While some agents are still largely dismissing and ignoring the self-publishing trend, others are figuring out how they can work with self-publishing in their business." Note: Chris is both self- and traditionally published.
On why traditional publishing is about more than a few weeks of chain bookstore distribution by Janni Lee Simner from Desert Dispatches. Peek: "I know what my editor has done for my books, and honestly, I don't think I could afford to buy that level of editing, let alone the years of experience behind it. Certainly we'd be talking thousands, not hundreds of dollars to do so."
Time Period Settings by Mary Kole from Kidlit.com. Peek: "The event or period really has to be central to the events of your own novel. In other words, there has to be a dang good reason for you to be setting your book in another time." See also Mary on Avoid the Obvious in a Query.

The inspiring digital imagery is segment of Wall Mirrors You Can Really Use written piece which is listed within Cheap, Mirrors, Interior and posted at July 3, 2015 1:43:01 pm by rchadmin
Wall Mirrors You Can Really Use: Cheap Wall Mirrors UK
Wall mirrors do a great job of opening up the visual space of a room. When you've got the right wall mirror, it becomes the perfect accent to a home. Here's how you can find a mirror that you can actually use.
Look for mirrors that are framed. A framed mirror provides a number of advantages. They are typically easier to hang. They can be framed to compliment any wall or room décor. They are even a natural point that catches the eye and makes the room seem inviting. Almost any material can be used to make a mirror frame, so choose the ones that are your favorite.
Love it? Buy it
Seamless mirrors are perfect for the bathroom. Wall mirrors without a frame are a good installation point for a bathroom, especially above a vanity. Install glass clips into the wall, slide the mirror into place, and then tighten the installation down. It's a very effective way to spend an hour of time remodeling a home.
Colored wall mirrors make an impact. By combining the features of stained glass with a mirror, a new look for any room can be achieved. Toughened or laminated mirrors can even help to make a home more secure when installed on an exterior wall.
Placement matters. The goal of a mirror is to make a room look bigger in some way. If you place a mirror too high or low on a wall, it won't be able to do this for you.
Wall mirrors are affordable, beautiful, and come in a wide variety of styles. Consider adding them to your home today and you may be surprised at how open a closed room can feel.

Class of 1975
Major/Minor: English
Laura Oliver is the author of The Story Within (Penguin Books/Random House,) named by "The Writer Magazine" as one of the best books of the year, and additionally selected by "Poets and Writers Magazine" as one of the best writing books published. In addition, Oliver is an award-winning writer and workshop instructor at St. John's College and The Writer's Center, and has taught both fiction and essay writing at the University of Maryland.
Oliver's fiction and essays are published in national newspapers, magazines and top-tier literary reviews. Among other distinctions, she is the recipient of a Maryland State Arts Council Individual Artist Award in Fiction, an Anne Arundel County Arts Council Literary Arts Award winner, a two-time Glimmer Train Short Fiction finalist, and her work has been nominated for a Pushcart Prize.
Oliver holds a Master of Fine Arts Degree in Creative Writing and Literature from Bennington College, a Bachelor of Arts in English from Washington College, and has completed writing seminars in creative non-fiction at the University of Iowa.
The Story Within
Laura's book The Story Within, New Insights and Inspiration for Writers was published by Penguin in November 2011.
"Writing is a duet of giving and receiving, and the writing spirit is a generous one. Plumbers spend time and energy learning to fix your pipes. You respect their skill and are grateful for their choice of livelihood when your pipes leak. But writers? Writers want to give you something enormous and impractical, something bigger than any page can contain. Given the means, writers want to give something that will amuse, entertain, last forever, and fix your pipes. We can't help it. It's our nature."
—excerpt, The Story Within

This book is fun to read and will make you a better writer." -Jon Franklin, winner of the Pulitzer Prize for Explanatory Journalism and the Pulitzer Prize for Feature Writing.
- "Blunt, witty, relentlessly honest about the hard simplicity of the writing craft, immensely useful, and startlingly thorough. As penetrating and stimulating a book as I have ever seen." - Brian Doyle, editor of Portland Magazine.
- "Laura Oliver writes with enormous humanity, humor, and a truly keen eye for human emotion. I would love to see anything else that Laura Oliver writes. She works a territory that I'm very comfortable with and she brings her own considerable talent to this turf."—Jane Rosenman, Executive Editor, Houghton Mifflin
- The Story Within, New Insights and Inspiration for Writers: "Oliver's book manages to be simultaneously eloquent, no-nonsense, inspirational, funny, and loaded with truly practical ideas: tantalizing essay openings; cool things to put on a writer's desk; specific ways to make dialogue work better; useful instructions to give people you've asked to read your paragraphs. I envy Oliver's students, who must thrive under her understanding and enthusiasm. I happened to pick it up during a week when I was in a foul mood about writing in general, and by the time I was halfway through, to my amazement, Oliver had made me want to sit down and get back to work." –Cynthia Gorney, Graduate School of Journalism, U.C.

The Day of the Field Trip Zombies illustration will appear here.
My favorite part is when the students turned into zombies, but they weren't dead zombies like in the movies. They were brain controlled. They had scary green faces and held their arms out when they walked.
I also liked the setting of the book. It would be fun to go to an aquarium for a class field trip and see the sharks. I wouldn't mind turning into a zombie and scaring my friends while we were there.
I would recommend this book to kids like me who want plenty of action and adventure. You need to like zombies, too, or you might be too afraid to read it.

Arthur Bleksley: pioneer of science awareness in South Africa
D.P. Mason
School of Computational and Applied Mathematics, University of the Witwatersrand, Private Bag 3, WITS 2050, South Africa. E-mail: firstname.lastname@example.com
Arthur Bleksley was born one hundred years ago, in 1908. In his early career, he undertook research in astrophysics and astronomy on variable stars. He was an outstanding university teacher of applied mathematics. He pioneered science awareness in South Africa through his scientific articles in the press, his radio broadcasts and his presentations at the Johannesburg Planetarium. An outline of Bleksley's life and career is given together with his contribution to research, teaching and science awareness.
On astronomy
It is work that does not bring dividends, but for those of us who look beyond material values and want to know about the Universe, who feel the mystery of life and to whom Nature makes a profound appeal, it is of more value than all the diamonds of Kimberley and all the gold of Johannesburg.
Jan Christiaan Smuts, at a meeting of the
Astronomical Society of South Africa,
8 February 1933.
The year 2008 marks the centenary of the birth of Arthur Bleksley. In the 1930s, Bleksley undertook research in astrophysics, and subsequently became respected by generations of South African scientists and engineers as an outstanding teacher of applied mathematics. The general public knew him as 'Mr Science' because of his ability to explain complicated scientific concepts in language that the layperson could understand.
In the early days, Bleksley was something of an embarrassment to his fellow scientists who disapproved of his popular scientific articles in the press and his scientific talks on radio,1 but during his lifetime there developed a complete change in attitude to science awareness worldwide. I review Bleksley's life and work and assess the contribution he made to research, teaching and science awareness in South Africa. Figure 1 shows the man in mid-career.
A short biography of Bleksley appeared in the Gazette of the University of the Witwatersrand (Wits)1 on his retirement in 1968. Short biographies have also been written by Burnton2 and Murray.3 The accompanying box sketches important events in his life and career.
Research and publications
Bleksley was the sole author in all 50 of the papers listed in the bibliography. He worked on his own, which was not unusual for that time. A thorough bibliography of published articles, books and certain radio scripts in Bleksley's library covering the period 1929 to 1969 was compiled by Burnton2 in 1970.
Bleksley's contribution to research was made mainly in the 1930s and in the area of astrophysics. He undertook a detailed statistical and analytical investigation of variable stars. He developed a mathematical model, largely due to Eddington,5 of radially pulsating stars, and compared the predictions of the model with observations for the Cepheid variable stars and the long-period variable stars such as the Mira variables. In his first paper on astrophysics [A1 in accompanying bibliography], he showed, using dimensional analysis, that any pulsating star independent of its constitution must satisfy a period-density law of the kind derived by Eddington. He made the assumption that the radiation from the Cepheid variables is black-body radiation and derived a relation between the temperature and the radius in these stars [A8, 15, 16, 18,19]. He studied relations between the period, luminosity and spectrum of the Cepheid and long-period variable stars [A22]. Later he performed a similar study of relations between their mass, luminosity and temperature [A26]. Bleksley also studied the oscillations of the atmosphere of a pulsating star and showed that the radial velocity of the atmosphere will differ in phase from that of the photosphere in a way that agrees with observations [A23]. A theory of the origin of the emission lines in the spectra of long-period variable stars was developed based on the theory of pulsations of the stellar atmospheres.
Bleksley also studied binary stars. He clarified a difficulty in the problem of the variation in the orbital elements of a binary star when one or both of the components is losing mass by radiation [A7, 13]. He also undertook a statistical study of the mass, density and radius of some eclipsing binary stars [A25].
Many of the papers published by Bleksley up to 1937 formed the basis of his doctoral thesis, much of which was published in the South African Journal of Science [A23]. Paper [A24] is a report on the research Bleksley conducted during his stay at Leiden Observatory in 1938 on the period and light curve of an Algol star discovered to be variable on plates taken at Johannesburg. Bleksley had three Letters to the Editor accepted by Nature [A7, 8, 11], summarizing new results, the full derivation of which he published later either in Zeitschrift für Astrophysik [A13, 16] or Astronomische Nachrichten [A18].
Bleksley published one paper on geometry [M1], which was based on his M.Sc. dissertation, and two statistical papers with geometrical interpretation [M2, 3]. Throughout the 1940s, he was interested in nuclear energy [N14], possibly due to its application in astrophysics [N5]. At the end of the 1940s and the beginning of the 1950s, he worked on quantum mechanics [Q1, 2] and cosmology [C14], and in the mid-1950s he developed an interest in solar energy. The knowledge of solar radiation that he acquired at the solar observatory in 1931 would have been useful. In 1954 he attended a conference on solar energy organized by UNESCO in India, and in July 1955 read a paper at the Grahamstown Congress of S2A3 on the problems of collection, use and storage of solar energy [S1]. In November 1955 he delivered a paper at a world symposium on applied solar energy at Phoenix, Arizona, and published a full report on the conference [S2]. By the end of the 1950s, the electronic computer had become available for research. Bleksley gave an analysis of the use of a computer to forecast the results of the South African general election of 1958 and the Republican Referendum of 1960, after the first few results had been received [G4, 5].
27 April 1908 Birth of Arthur Edward Herbert Bleksley in Matatiele in East Griqualand (now South Africa's Freedom Day). Inaugural meeting of the first Council of the Royal Society of South Africa.
Schooldays Son of a postmaster, the young Bleksley completed Standard 8 in Steytlerville in the Karoo. He retained affection for the region, saying later that the only other place he might have enjoyed living in was Arizona, as it reminded him of where he grew up. He never felt at home in England although his forebears were British.
1925 On his father's advice, Bleksley entered the University of Stellenbosch, where he studied mathematics and physics as majors, read widely, became fluent in Afrikaans, and even studied Greek and Hebrew.
1927 Bleksley obtained his B.Sc. degree cum laude.
1928 Obtained his M.Sc. degree cum laude in mathematics and physics; received the van der Horst Prize.
19291930 The Union Postgraduate Fellowship for fürther study and research enabled Bleksley to conduct research in astrophysics on variable stars at the universities of Stellenbosch and Cape Town. He worked under J.K.E. Halm, formerly chief assistant at the Royal Observatory in Cape Town.2 In 1929, he became an assistant in the Department of Mathematics at the University of Stellenbosch, and in 1930 a temporary lecturer in the Department of Applied Mathematics at the University of Cape Town.
1931 Bleksley was a research associate in the Smithsonian Institution's Solar Observatory at Mount Brukkaros, the caldera of an extinct volcano, near Keetmanshoop, Namibia (then South West Africa). The observ- atory, comprising a 10-m-deep tunnel in the side of the mountain with a solar telescope at its entrance, was one of several observatories established at high altitude locations to collect solar radiation data, to investigate a correlation with the Earth's weather. (It closed in December 1931 and was moved to the Sinai peninsula.) On 1 September, Bleksley joined Wits as a junior lecturer in the Department of Applied Mathematics and Astronomy (see Fig. A in supplementary material online). Here he remained for the next 37 years.
6 August 1937 Bleksley obtained his D.Sc. degree at Wits. At his wife's insistence, he had submitted his thesis entitled 'The pulsation variables: an analytical and statistical study of stellar variability'. The three external examiners were Halm, under whom Bleksley had worked when he held the Union Postgraduate Fellowship; Harlow Shapley, who first proposed the pulsation theory to explain regular stellar variability; and Sir Arthur Eddington, who developed the theory mathematically.
1938 Bleksley was granted sabbatical leave and travelled abroad to continue research in astrophysics. He visited the University of Cambridge (U.K.) to work with Eddington; Leiden Observatory (the Netherlands) to work with Ejnar Hertzsprung; and the University of Göttingen (Germany) to work with Hans Kienle.
1940 Bleksley was promoted to senior lecturer. Wits also awarded him the H.B. Webb Fellowship for 1940, but World War II prevented him from taking it up. He served in the infantry sub-unit of the Rand University Training Corps, and put his knowledge of astronomy to practical use by designing a universal sun compass, which was accepted by the Union Defence Force and proved valuable in the desert war in North Africa.
1942 Bleksley was appointed to the Council of the South African Association for the Advancement of Science (S2A3), with which he had a long and active relationship. He became president of Section A in 1943, and honorary general secretary in 1948, a position he held for the next 25 years.
19491950 He served as president of the Astronomical Society of South Africa for 194950.
19511956 In August 1951, on Herbert Le May's retirement as professor of applied mathematics and head of the Department of Applied Mathematics and Astronomy, Bleksley was appointed acting-head. Murray3 has described the procedure leading to the filling of the chair. The first advertisement sought applicants with 'research interests in Theoretical or Mathematical Physics who will be able to assist in the higher training of physicists'. The selection committee recommended the appointment of a Canadian with a good research record but little teaching experience. The Senate, concerned about undergraduate teaching, referred the appointment back to the selection committee. The chair was re-advertised without specification of research interest and, on 1 February 1953, Bleksley became chair of Applied Mathematics and head of department, positions he held for the next 15 years. He delivered his inaugural lecture, 'The problems of cosmology', on 4 April 1956.
19581960 As president of S2A3 (July 1957July 1958), he delivered the Presidential Address, 'Science and society', at the association's annual congress in Lourenço Marques (now Maputo) in 1958. In the same year he founded the Science Writers Association of South Africa and was elected its first president. He was a member of the Faculty of Science of the Suid-Afrikaanse Akademie vir Wetenskap en Kuns and, in 1960, recognizing his scientific achievements, the Royal Society of South Africa elected him a Fellow. Also in 1960, Bleksley was appointed director of the Johannesburg Planetarium. He was the main person responsible for the establishment of the Zeiss Planetarium and for its purchase by Wits.
1964 Bleksley's interest in parapsychology won him the Eighth McDougall award for research in the subject. The award (made by Duke University, North Carolina, USA, for the most outstanding paper on extra-sensory perception during the preceding year) was worth US$1 000. His paper (listed in the bibliography as [P1]), dealt with an investigation on making a person in Cape Town waken at times set by an alarm clock in Johannesburg.
1968 In August, Bleksley retired as director of the Planetarium (see Fig. B online) and, on 31 December, from the chair of Applied Mathematics and the headship of the Department of Applied Mathematics and Astronomy (see Fig. C online). He took with him the name plate on his office door and attached it to the door of his study in his Parkview home. Thereafter, he visited the department only when invited.
Retirement His was an active retirement. He continued with his radio work and in 1977 received the Artes Award for Best Broadcaster (see Fig. D online). After a stroke in that year, he continued writing the radio programmes for a few weeks even though his voice was no longer heard on air.
July 1984 On 8 July, he was rushed to hospital suffering from an aneurysm. He died peacefully at 08:15 the next morning, 9 July 1984, aged 76. He was survived by his wife, daughter, and grandchildren.
A significant feature of Bleksley's research in astrophysics was the checking of theory against observations and he developed a good working knowledge of statistics. His other publications were mainly reviews, some presidential addresses, which pointed the way to important areas of research. Statements were generally supported quantitatively with numerical data. Bleksley recognized early new areas of investigation that would become significant in the futurenuclear and solar energy, interplanetary space travel, a unified theory of cosmology and quantum mechanics, and the computer prediction of election results.
Bleksley believed that a teacher's job is to open doors, on the basis that the more doors you can see the more you can open. He did not become totally specialized and tried to retain a broader approach to applied mathematics. He saw the teacher as a link to the narrow specialist, not knowing as much as the specialist but knowing more than the non-specialist. His department was responsible for lecturing applied mathematics to students in the faculties of Science and Engineering, and, over the years, Bleksley taught most of the courses it offered. He taught mechanics to generations of engineering graduates, many of whom later held important positions in industry, in South Africa and abroad.
Bleksley wrote two textbooks on mechanics, which went through several editions and were widely used in South African universities. The second volume contained chapters on the equilibrium and motion of fluids and on oscillations of continuous systems. His textbooks contain many worked examples and they list exercises for the student at the end of each chapter. It is generally recognized that his books contributed significantly in placing the teaching of mechanics in South Africa on a sound basis.
Bleksley did not teach from notes. His lectures were models of clarity, and he used simple language even when explaining the most difficult concepts. Students enjoyed the pleasant, relaxed atmosphere in his classes, his sense of humour, and the fact that he never got angry, and they found him very approachable despite his many other responsibilities. Anthony Starfield, Bleksley's student in the 1960s and his successor as professor of applied mathematics, comments (pers. comm.):15
He was the best of teachers and the worst of teachers best because he was so crystal clear, worst because he made everything sound so logical and simple that most students assumed they had mastered the material just by listening to him. It worked for good students, but was fatal for weaker students.
Bleksley found that, while universities in South Africa had changed, the students had not: 'Students still have the same ideals. They still want to work and achieve the rewards.' He was honorary president of many student societies.
The Johannesburg Planetarium was the first full-sized planetarium in Africa and the second in the southern hemisphere. Bleksley [G5] described the events leading to the establishment of the Johannesburg Planetarium at Wits in 1960 and its purchase from the City of Hamburg in Germany by the City of Johannesburg to mark the 70th anniversary of the founding of Johannesburg.
During his years as director of the Planetarium (196068), Bleksley gave 2000 lectures there. At that time of active space exploration, he informed the citizens of Johannesburg about the significance of the events taking place. A special function was organized by S2A3 at the Planetarium, attended by about 100 guests, to mark Bleksley's last lecture as director on 19 August 1968. Before the start of the lecture, Raymond Dart presented Bleksley with a scroll commemorating eight years as director and 20 years as secretary of S2A3, and praised him for carrying 'this university [University of the Witwatersrand] into the city'. Later in the year, the Wits vice-chancellor and principal, Professor I.D. MacCrone, wrote to Bleksley on his retirement to convey the university council's gratitude for bringing the Planetarium into being, for ensuring its success as an educational amenity for the citizens of Johannesburg and their children, and for his guidance as director (Fig. C online).
Radio broadcasting
In the early days of broadcasting, some academic colleagues felt it unprofessional for a professor to give radio talks. They thought he was letting the side down by going into the marketplace and talking to the people. Bleksley firmly believed, however, that not only were people entitled to know what scientists were thinking, but they also desperately wanted to know.
The successful talks on astronomy for the Afrikaans children's programme were followed by Bleksley's talks on science and radio plays. The subjects of some of these plays were famous scientists such as Archimedes, Marie Curie, Darwin, Edison, Galileo, Herschel, Marconi, Pasteur, Röntgen and Rutherford. The topics in his radio plays for schools included the makers of science, modern discoveries such as penicillin, man in space, and the wonders of a starry sky.2 By 1953, he had delivered 400 broadcast talks on science and authored 50 radio plays. But he could not really afford the time, especially as the rewards were only 35 cents per minute of broadcasting. Two series of radio plays on scientific topics, written for school broadcasts, were recorded and made available in other countries by UNESCO.1 Bleksley's 'gravelly' voice became familiar to thousands of listeners through the three programmes, Log Book, The Voice of Science and Test the Team.
Test the Team was broadcast on Springbok Radio (19571985) and on Radio South Africa (198688). The original members of the panel were Grant Louden in Durban, and Eric Rosenthal and Arthur Bleksley in Johannesburg; the presenter was Dewer McCormack in Cape Town. The broadcast was live and the members of the panel and presenter communicated by telephone while on air. Although Bleksley and McCormack met, briefly, only once, they formed a friendship over the telephone. If there was a question the panel could not answer, Bleksley would encourage the panel to analyse the question and deduce the answer. Louden said that Bleksley had the 'finest deductive brain' of any person he had come across.
Bleksley retired from radio broadcasting in 1977 after about 40 years, during which time it is estimated that he spoke more than five million words into the microphone (Fig. D online).
Bleksley's voice on the radio has been described as somewhat slow and calculating as he thought carefully about what he was saying, using straightforward language to explain complicated science. But he was not completely happy with radio as a medium of communication, observing: 'You speak, hundreds of thousands may hear you. Then your words are gone forever.' He kept the scripts of all his radio talks in leather-bound volumes in his study at home, thinking that someone might like to read them one day and that they might become valuable Africana. His scripts may be of interest to students in the field of science education and journalism.
The press
Bleksley wrote more than 400 popular articles on science in the South African press, with whom he always actively cooperated. Burnton's bibliography1 includes many of these articles. Every newspaper group and the SABC contributed willingly and generously to the function at the Planetarium on 19 August 1968 that marked Bleksley's last lecture as director. Paying tribute to Bleksley before the lecture, the president of the Newspaper Press Union called Bleksley a 'pressman's dream', at all times polite and helpful.
An example of Bleksley's helpfulness is given by Ian Reid, who, in 1955, was a young reporter for the South African Press Association in Johannesburg, travelling by train to Grahamstown for the S2A3 annual congress. Bleksley was presenting a paper [S1] on solar energy at the congress and was on the same train. They met in the dining saloon, Bleksley with his wife and very young daughter. Reid was carrying about eight advance copies of papers to be presented by delegates, which he had to put into understandable English but even whose titles he did not understand. Bleksley took the papers and instructed Reid to call at his hotel in Grahamstown after eight that evening. In the interim, Bleksley put each paper into layman's language for him.
Bleksley was instrumental in founding the Science Writers Association of South Africa in 1959. In his 'Science and society' address in Lourenço Marques in 1958, he had suggested that such an association be founded in South Africa, to encourage good science reporting [G3]. Bleksley became its first president. In 1964, the association introduced a bronze medal, the Bleksley Medal, awarded annually to the South African journalist who makes the most significant contribution to science writing. Commenting on the award, the Rand Daily Mail said that, honouring Bleksley, it carried the fitting name of one who 'in making science understandable to the public has demonstrated that lucidity does not require the sacrifice of validity'.
The man
Bleksley has been described as warm and friendly, benign, affable, with a sense of humour, wide forehead, eyes twinkling behind horn-rimmed glasses, and old world manners. He talked fluently in technical scientific language in both English and Afrikaans. From his early life in the Karoo he could speak Xhosa. He read widely, including poetry and science fiction, and he remembered what he read.
He regarded himself as 'an amateur in the good sense of the word'. His isolation in his early years of research meant that he had largely trained himself as a researcher. Many eminent past scientists, such as G.I. Taylor in fluid mechanics, also called themselves amateurs, and, Bleksley observed [G3], Darwin, Mendel, Herschel, Marconi and Franklin too were largely self-trained amateurs.
As he explained in his Lourenço Marques address in 1958 [G3], Bleksley believed that scientists must be prepared to play their part in educating the lay public about science. The public is aware that it needs to know about science, and there is an audience waiting. He saw the universities as having an important role 'as the centre of the intellectual life, not merely of a few thousand students and a few hundred members of its staff, but of the entire community which it exists to serve.' He believed that universities should encourage many more people to participate actively in science and not merely listen passively. Universities can reach only a small part of the total population and they needed help from the radio and the press, for 'both possess the right of entry to almost any home in the civilized world.' He thought that science coverage in newspapers and radio programmes was not in proportion to the importance of science. By the time of his retirement scientists' attitudes had changed: 'Scientists no longer live in ivory towers. To-day I cannot think of anyone who would not take part in a discussion on radio or television if asked.'
Bleksley believed that more women should be encouraged to consider higher education and be told of the promising future awaiting them in science [G3]. He understood the economic pressures that forced girls to leave school early, and the need to provide adequate financial assistance through bursaries and scholarships. He was always prepared to assist less privileged South Africans. Among many he helped was Kantilal Naik, who, until his retirement in 2003, was a senior lecturer in the School of Computational and Applied Mathematics at Wits. It was Bleksley who arranged a study bursary at Wits for him and later provided moral and academic support during Naik's detention by the Security Police in the early 1970s.6
Bleksley's early research in astrophysics on variable stars was known beyond South Africa. After World War II, he did not resume his work on astrophysics and his subsequent publications were mainly review papers. His choice of subjects showed prescient judgment of fields that had future importancenuclear and solar energy, interplanetary space travel and computer applications.
He may have been influenced by the example of Eddington, who had made general relativity and quantum mechanics accessible to the public in the 1920s and 1930s through his lectures and books and on the air. Bleksley's broadcasts, popular scientific articles in the press, and directorship of the Johannesburg Planetarium did the same for South Africa.

6. Dr Naik remembers his association with Bleksley as follows:
'My first meeting with Professor Bleksley was in 1958 when I went with my late father and family friend to see him to seek guidance relating to my studies at the University of the Witwatersrand in 1959. He was friendly and asked me what I wanted to do. I told him that I was keen on studying for pharmacy, to which he replied jokingly, 'Pharmacists sell more cameras than they sell medicines'. The following year I enrolled for a B.Sc. degree with applied mathematics and chemistry as major subjects.
While studying, I lost my father in 1960. I had difficulty in paying fees and approached Professor Bleksley for assistance. He was extremely helpful and as chairperson of the bursary committee he arranged a bursary for me. He was always prepared to help less privileged students.
When I was a science teacher at Roodepoort Indian High School, I wrote a textbook Calculations in Physical Science for matriculants and first-year university students. After studying the contents, Bleksley gave me a very positive foreword for the book.
When I was detained by the Security Police in October 1971 for almost six months at John Vorster Square in Johannesburg, Professor Bleksley wrote a testimonial on my behalf. The police brought the testimonial to my cell to show me. I had tears of appreciation in my eyes. The testimonial undoubtedly helped me during my detention.
When I completed my doctoral thesis, Bleksley was one of the persons to whom I dedicated my work, in appreciation of his invaluable help to me.'
