I am currently in the writing phase of my thesis. Factors related to and unrelated to academia are putting me under "nice" amount of pressure. it became much harder for me to concentrate on reading or writing and always end up procrastinating much of the time.   What are good strategies to get back on track in regards to managing my thesis work? When should one consider psychiatric counseling?
Background - I am doing my PhD in atmospheric physics/photobiology.  Here is a scenario:   The experiments are complete - the results are far better than expected  Successfully got the computer program to work properly and have developed another Papers are published Much of the thesis is drafted   The light at the end of the tunnel is most definitely no longer an oncoming train.  But, at this stage, you just don't feel like working on the thesis, you do other things like cleaning, reading, watching movies - procrastination gets worse, and worse despite the submission deadline coming closer.     The procrastination resulting in more apathy towards the project, despite being fully aware of how much work has been put into the project, how much has been achieved and how little, comparatively, needs to be done.  What strategies are there to overcome this academic-apathy, particularly in this late stage of the thesis?
If $f'$ is bounded, then $f$ is uniformly continuous Let $f\colon(a,b) \to \mathbb R$ be differentiable and suppose that there exists an $M&gt;0$ such that $|f&#39;(x)| \leq M$ for all $x$ in $(a,b)$. Prove that $f$  is uniformly continuous. How can I keep multiple live/bootable ISO images on a single USB drive? I am looking to create a USB flash drive that I can put multiple  ISO images on and select which boots from startup. The ideal candidate supports Linux and Windows-based ISO images, and is relatively simple. It also must have some reasonable process for adding and removing an ISO image from the drive/list.    Things that I'm not looking for in this specific question:    or other swiss-army knife live CDs. The point is to boot any one of multiple CDs, not to boot a (certainly useful) utility CD. Installing a single live CD to a USB drive. I'd like to have multiple ISO images, selectable at startup.   I don't have a specific purpose in mind, possibilties include a single drive with a  variant, Ubuntu desktop, UBCD4Win for DOS, the Offline NT Password Cracker, etc.  Flexible and easy to use are the name of the game! Named Credentials - Merge Fields not Resolving Redefining "cited on" string (and others) in biblatex Is the universe fundamentally deterministic? I'm not sure if this is the right place to ask this question. I realise that this maybe a borderline philosophical question at this point in time, therefore feel free to close this question if you think that this is a duplicate or inappropriate for this forum. Anyway, I'm an electrical engineer and I have some basic knowledge of quantum mechanics. I know that Schrödinger's equation is deterministic. However, quantum mechanics is much deeper than that and I would like to learn more. If this question is not clearly answerable at this point than can anyone point out some recognized sources that try to answer this question. I would appreciate it if the source is scientific and more specifically, is related to quantum theory. solution for apex cpu time limit exceeded exception Many introductory quantum mechanics textbooks include simple exercises on computing the de Broglie wavelength of macroscopic objects, often contrasting the results with that of a proton, etc.  For instance, this example, taken from a textbook:     Calculate the de Broglie wavelength for      (a) a proton of kinetic energy 70 MeV      (b) a 100 g bullet moving at 900 m/s   The pedagogical motivation behind these questions is obvious: when the de Broglie wavelength is small compared to the size of an object, the wave behaviour of the object is undetectable.  But what is the validity of the actual approach of applying the formula naively? Of course, a 100g bullet is not a fundamental object of 100g but a lattice of some $10^{23}$ atoms bound by the electromagnetic force. But is the naive answer close to the actual one (i.e. within an order of magnitude or two)? How does one even calculate the de Broglie wavelength for a many body system accurately? When should I have an NPC actively investigate an illusion created by the Phantasmal Force spell? The phantasmal force spell can be broken if the victim examines the illusion and makes a successful investigation check against the spell's DC.  What general guidelines should I use to decide when the victim of phantasmal force should use its action to examine the illusion?  Suppose the caster makes an orc think it is being attacked by a wolf.  Should the orc always examine the wolf until the spell ends? Or should the orc use its action to attack the wolf, defend itself, or run away? More Efficient Spatial join in Python without QGIS, ArcGIS, PostGIS, etc I'm attempting to do a spatial join much like the example here: . However, that approach seems really inefficient / slow. Even running this with a modest 250 points takes almost 2 minutes and it fails entirely on shapefiles with > 1,000 points. Is there a better approach? I'd like to do this entirely in Python without using ArcGIS, QGIS, etc.  I'd also be interested to know if it's possible to SUM attributes (i.e. population) of all the points that fall within a polygon and join that quantity to the polygon shapefile.       Here is the code I'm trying to convert. I get an error on line 9:  poly['properties']['score'] += point['properties']['score']   which says:     TypeError: unsupported operand type(s) for +=: 'NoneType' and 'float'.    If I replace the "+=" with "=" it runs fine but that doesn't sum the fields. I've also tried making these as integers but that fails as well.  with fiona.open(poly_shp, 'r') as n:    with fiona.open(point_shp,'r') as s:     outSchema = {'geometry': 'Polygon','properties':{'region':'str','score':'float'}}     with fiona.open (out_shp, 'w', 'ESRI Shapefile', outSchema, crs) as output:         for point in s:             for poly in n:                 if shape(point['geometry']).within(shape(poly['geometry'])):                       poly['properties']['score']) += point['properties']['score'])                     output.write({                         'properties':{                             'region':poly['properties']['NAME'],                             'score':poly['properties']['score']},                         'geometry':poly['geometry']}) I want to type Arabic text in Photoshop, but the text appears disjointed and the letters do not connect at all. For example محمد appears as م ح م د.   I'm using Photoshop CS6 on OSX Mountain Lion. Transcendental numbers and irrationality measure Multiple tags search broken when searching as anonymous user? When I input [asdf][lisp] into the search field on , without being logged in, only one tag remains. Is it broken? Why was Sam Wilson chosen for this, but not Bucky? At the end of the Avengers: Endgame movie,      old Steve Rogers passed down his mantle of Captain America   to Sam Wilson.  Why didn't he choose Bucky for this? Bucky seems more fit for the job as he is a super soldier. How to install the latest stable version of Chromium? Is there an easier way to install Chromium than what is described ?  Furthermore, is there an easier way to stay up to date with current Chromium releases rather than having to re-build Chromium each release? (a script which automatically grabs and installs the latest build possibly?).  Related: A way to store potentially infinite 2D map data? I have a 2D platformer that currently can handle chunks with 100 by 100 tiles, with the chunk coordinates are stored as longs, so this is the only limit of maps (maxlong*maxlong). All entity positions etc etc are chunk relevant and so there is no limit there.  The problem I'm having is how to store and access these chunks without having thousands of files. Any ideas for a preferably quick &amp; low HD cost archive format that doesn't need to open everything at once? The Borel-Cantelli Lemma in  seems to be a sort of "corollary" of the .  It says:  "Let $(E_k)_{k=1}^{\infty}$ be a countable collection of measurable sets for which $\sum_{k=1}^{\infty} m(E_k) &lt; \infty$. Then almost all x $\epsilon \ \mathbb{R}$ belong to at most finitely many of the $E_k$'s"  I don't get three things:   "Then almost all x $\in \ \mathbb{R}$ belong to at most finitely many of the $E_k$'s"   What does that mean? Since the Borel-Cantelli Lemma comes after the "almost everywhere" definition, I guess: $\exists \ Z \ \subset \mathbb{R}$ s.t. $m(Z) = 0$ and $\forall x \ \in \ \mathbb{R} \setminus Z$, x belongs to $(E_{j}, E_{j+1}, E_{l}, ..., E_{m})$.   In the proof, one can see the $m(\limsup \ E_k) = 0$ part, stated as $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$. For some reason, $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$ implies that "Therefore almost all x $\in \ \mathbb{R}$ fail to belong to $\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]$ and therefore belong to at most finitely many $E_k$'s"   Okay, why? What is the contradiction if almost all $x \epsilon \ \mathbb{R}$ belong to all the $E_k$'s? Or a countably infinite subcollection?   What is the significance of this? Why not just state the Borel-Cantelli Lemma as "Let $(E_k)_{k=1}^{\infty}$ be a countable collection of measurable sets for which $\sum_{k=1}^{\infty} m(E_k) &lt; \infty$. $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$"? Clearly this is an edge case and I probably shouldn't have even tried awarding the bounty to a deleted answer, but why is the bounty award button even available?  It's not a bug since someone added in the notification seen in the final image.  But that sure seems like a roundabout way to let the user know that they can't award a bounty to a deleted answer.  The second step is particularly strange since the system really ought to know that the warning is pointless: no bounty can be awarded.  My suggestion is to rip-off the  and let bounties be awarded without the warning.  Then remove the single click button from deleted answers. There are a number of times in Lord of the Rings where the "east" is mentioned -- the pirate ships, the slave-driven farms. And of course all of the peoples subservient to Sauron who come to fight Gondor and the West. Are there any maps of the East of Middle-earth, and what is out there? Is there a correct resistance value for I2C pull-up resistors?
