Plot Details/Summary Another one of my &quot;long shot specials&quot;, I'm afraid. The show was some sort of sci-fi adventure set on Earth or an Earth-like planet.  There is a mixed group of survivors/adventurers who are brought together somehow and all put into the situation they are in. I believe all of the characters are humans and from Earth. The one thing I can really remember from the show is that one of the characters had a wand-like device that had a clear glass or plastic &quot;tuning fork&quot; on the end of it.  The character could focus his thoughts or will through the device, which would glow and do things like shatter glass, etc. That's about all I can recall.  I don't know if it was only a tv pilot, or if it went to series.  It was definitely an American or Canadian produced show (i.e. it was not British) and I'm almost certain it was broadcast by one of the major tv networks. Timeframe Mid-to-late 1970s.  I think it was probably later in the 70s, though I'm not certain of that.
I'm trying to identify a science fiction series on UK TV during the 70s, but I can only recall the following:   A party of adults and children. There was a woman with a telepathic bond to her cat: she could look into its eyes to see what it had seen. Time travel was involved. I think it may have been inadvertent or uncontrolled time travel. On one occasion the party encountered an Elizabethan seaman who demanded to know if Elizabeth was still queen. They party replied "err... yes" because they didn't want to have to explain time travel.
Bell's inequality theorem, along with experimental evidence, shows that we cannot have both realism and locality.  While I don't fully understand it, Leggett's inequality takes this a step further and shows that we can't even have non-local realism theories.  Apparently there are some hidden variable theories that get around this by having measurements be contextual.  I've heard there are even inequalities telling us how much quantum mechanics does or doesn't require contextuality, but I had trouble finding information on this.  This is all confusing to me, and it would be helpful if someone could explain precisely (mathematically?) what is meant by: realism, locality (I assume I understand this one), and contextuality.  What combinations of realism, locality, and contextuality can we rule out using inequality theorems (assuming we have experimental data)? "I cannot seem to find it" Ubuntu in VirtualBox wants to install on every boot Science Fiction novel or novels about starship that becomes a god, colonizes hostile planet Plot Summary/Details  The sharpest memory I have of this one is that it was unusually dense reading. Much more difficult going than most of the sci-fi stuff I'd read by that time (I was 10 or 11, I think).  What I remember in terms of plot is that there is a starship, sent either to explore, or colonize, a distant star system.  I don't remember the names of any of the characters, but I think maybe they discover they are clones?  In any case, something happens to the computer system that the onboard AI becomes sentient and develops a measure of omniscience and omnipotence.  It effectively becomes a god of sorts.  The next part I can remember, and I'm not sure this is the same book or not, is that the ship has forcibly settled the crew on a hostile planet.  All sorts of nasty indigenous life forms live here, and guards are post on the wall outside the settlement to destroy them as they try to enter.  I remember there is a female character standing watch, and she goes over the bestiary in her mind.  One particularly nasty creature paralyzes you, and then burrows up your spine into your brain (or something like that) if it gets a hold of you.  That's all I can recall.  Not a lot of detail, unfortunately, but I'm having a tough time remembering much about this one.  I never finished the book(s), as they were mostly "over my head" at that age. Is there a way to change the restrictions passcode on an iPhone without restoring the phone? I haven't forgotten the passocde; I just want to change it. It is often stated that the Lagrangian formalism and the Hamiltonian formalism are equivalent.   We often hear people talk about eigenvalues of Hamiltonians but I have never ever heard a word about eigenvalues of Lagrangians.   Why is this so? Is it not useful? is it not possible to do it? The following sentence refers to an apocalyptic story where money no longer has any value:     A can of sardines, radio batteries, or a bicycle is/are more precious than money.   Should I use is or are after the series? polyglossia or bidi bug: [\d\.] gets inverted to [\.\d] After bidi was updated to v. 19.6 (2016-05-23), using at least one RTL language with polyglossia leads to number and following dot being inverted.

Because of this I have not opened an issue on polyglossia's github page.

"Not with a whimper, but with a roar of triumph!" Looking for the title of an old sci-fi book, pretty sure it is a Baen or Del Rey imprint. Basically, mankind has reached the stars and expanded throughout the galaxy. Suddenly, an unknown race appears and begins a war of extermination against man. Finally, the galaxy is desolate, and one man remains. He is in a starship with an AI and becomes injured in the battle.  The ship's AI takes over and speeds out into the unknown, followed by the last remaining member of the unknown alien race. As all speeds are at tremendous multiples of the speed of light, the man cannot get away, but the alien cannot catch up.  Finally, communication is opened, at which point the man asks "why?" The alien tells him that man had discovered immortality, but that it required the death of a member of a race known as the Flower People for every human who achieved immortality. The alien says that Man would have found the answer eventually, but that genocide was so intolerable that the aliens came from another dimension, to which they could never return, to stop Man, which resulted in the war of extermination.  Finally, the light speeds become so great that the two remaining living beings in the universe approach the Big Crunch. As the Man begins to dive into the singularity, with the alien hot on his heels, he says that maybe there will be room in the next universe for both races to live in peace, and the final line is "not with a whimper, but with a roar of triumph"! Is it valid to have more than one question mark in a URL? I want to see what nodes exist under a certain domain from within the domain. Short of querying every valid IP address within that domain, is there a way to get all records/map the network? Confidence interval interpretation in linear regression when errors are not normally distributed The force of gravity is constantly being applied to an orbiting object.  And therefore the object is constantly accelerating.  Why doesn't gravity eventually "win" over the object's momentum, like a force such as friction eventually slows down a car that runs out of gas?  I understand (I think) how relativity explains it, but how does Newtonian mechanics explain it? How can I echo a newline in a batch file?

Does it have any correlation with the mass/number density of the medium? In other words is an optically denser medium must have a greater mass density compared to an optically rarer medium? Modify footer used by elsarticle.cls How can I clear event subscriptions in C#? Take the following C# class:  c1 {  event EventHandler someEvent; }   If there are a lot of subscriptions to c1's someEvent event and I want to clear them all, what is the best way to achieve this? Also consider that subscriptions to this event could be/are lambdas/anonymous delegates.  Currently my solution is to add a ResetSubscriptions() method to c1 that sets someEvent to null. I don't know if this has any unseen consequences. What part of speech is "back" in "put the book back on the table"? Put the book back on the table.   I'm having trouble. I think it is a preposition. How can I find out the size of a block device, such as /dev/sda? Running ls -l gives no useful information.
