50s Sci Fi book: "Superbomb" sends town to far future with Sun a red giant star I once read a book about 40 years ago that was from the early 1950s.  The premise was a scientist working on a "Superbomb" (described as a Hydrogen bomb) in a rural American town/city. An atomic war breaks out and the city is hit.  The bomb doesn't destroy the town; instead the town is catapulted millions of years into the future where the Sun is a growing red giant star and humanity is long gone.  Aliens find the town and help the folk out somehow.
Book about a town that is transported by an explosion into a freezing desert It starts with a town that was hit by a mysterious explosion which transports that town into a desert. The weather is cold and people burn coal but they soon run out and send out an expedition to look for signs of life - they navigate the desert for a couple of days and come across a glass dome covering a city. Apparently they have been transported far in the future.  And that's where I stopped reading and want to resume now. Don't remember the title or the author and it's at least 20 years old.
Is there a way to see that $ \nabla_\mu g_{\nu \rho} = 0 $ without explicit computation, where $\nabla_\mu$ refers to the covariant derivative? In books, it is usually said that this is a consequence of the fact that parallel transport preserves dot product. How ? arbitrary large finite sums of an uncountable set. What happens when I terminate a process and the socket send buffer is not empty? In Windows (and probably in other operating systems), if a process has a TCP connection with another process on another machine, and then I terminate the process, an RST packet will be sent to the other machine to indicate the end of the connection.  Now imagine that when the process is terminated, there were still some data left in the send buffer. What will happen in this case, will these remaining data be sent to the other machine followed by an RST packet, or will these remaining data be ignored and only an RST packet is sent? Do tag edits count for Archaeologist? I know tag-edits do not count towards the 500 edits required for the Copy Editor badge. Do they count to the 100 for the Archaeologist badge? It seems they should because you are making a 6-month-inactive post active again. extended stars-and-bars problem(where the upper limit of the variable is bounded) The problem of counting the solutions $(a_1,a_2,\ldots,a_n)$ with integer $a_i\geq0$ for $i\in\{1,2,\ldots,n\}$ such that $$a_1+a_2+a_3+....a_n=N$$ can be solved with a stars-and-bars argument. What is the solution if one adds the constraint that $a_i\leq r_i$ for certain integers $r_1,\ldots,r_n$?  e.g. for $n=3$, $N=6$ and $(r_1,r_2,r_3)=(3,3,2)$, the tuple $(a_1,a_2,a_3)=(2,3,1)$ is a solution, but $(2,1,3)$ is not a solution because $a_3=3&gt;2=r_3$. How do I add CSS & JavaScript to ? I want to add the following code in my  section of the front page using a Drupal 8 sub theme of Bartik.   Can anybody help how to do it? What is the best way to do it in this new twig version of theme? Where is page.tpl?  &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="stepcarousel.js"&gt;&lt;/script&gt; Why does shrinkage work? How do you keep parents of floated elements from collapsing? Why is "that"/"which" omitted in this sentence? My 3 years old doesn't tell me when he needs to use the bathroom My son is 3 years old and doesn't tell me when he needs to use the bathroom. It has been 5 months now that I took his diaper off him. I just do not know what I should do.  Should I put a diaper on him again?  I mean, is this normal? Please help. I get frustrated sometimes.  He doesn't want to potty at all! I did train him before but now that he understands, he doesn't want to go to potty. Renting a car in Ireland & Great Britain: 1 rental or 2? My wife, two kids and I will be traveling in Ireland and the UK Nov. 1st through 21st. We're flying into and out of Dublin. Our plan is to do a clockwise tour: Fly into Dublin -> Belfast -> Scotland -> England/London -> Back to Dublin to fly home.  We've been planning to rent a car when we land in Dublin (doing just things outside Dublin at the start of the trip) and have a car all the way until London, then turn in the car and take a train/ferry to get back to Dublin before flying home.  However, reading through the car rental section of Rick Steve's 2012 Ireland book is causing us to question if this is the right plan.  He says (p. 480):     If your trip covers both Ireland and Great Britain, you're better off   with two separate car rentals, rather than paying for your car to ride   the ferry between the two islands. On an all-Ireland trip, you can   drive your rental car from the Republic of Ireland into Northern   Ireland, but be aware of drop-off charges ($75-150) if you return it   in the North.   So it seems like he recommends against doing one car rental for both islands, but he also recommends against renting in the Republic of Ireland and returning it in Northern Ireland (our other option for our current itinerary).  So we're not sure which is best here.  A few questions about this:   If we do one car rental all the way from Dublin to London, will there be a similar $75-$150 fee? Is there an easy place to return a car on the Northern Ireland side of one of the Northern Ireland -> Scotland ferries, and an easy place on the Scotland side to rent a car?  We'd like to minimize the number of buses/whatever we need to take between car rentals since we'll be lugging around car seats for both of our children (on top of carrying them and our luggage). Will one way be significantly cheaper than the other?  Besides the basic cost of taking the car on the ferry and the drop-off charges, our credit card will cover insurance in Scotland/England but not in Ireland, so we could potentially get a better rental rate by renting a second vehicle once we're on Great Britain. Although, I know you often get a better rate when keeping a car rental for longer, so that may negate any benefit from the credit card covering the insurance. What are the proposed theoretical explanations for the EmDrive? Quick edit not recorded as such blocking vote change A little background:  I do not know what the specifics are, but I've noticed that a quick edit after a post will often times not result in an edit being posted. It's as if there was no edit. Edit: According to Bart this amount of time is five minutes.  The problem:  A user made a really bad post (said that ~ in C# wrt integers was used for deconstruction). I down-voted said post. Post quickly disappeared (I guess poster realized they screwed up and took back the post). Later, I come back and see my down vote but the answer is now correct (that ~ is the bitwise complement operator). I try to get rid of my down vote because it is no longer appropriate. However, it has been about half an hour and there is no edit posted (presumably the poster made an edit within the non-posting edit window) so I can't take my vote back.  Suggested solution:  If post gets edited (even within the non-post edit window) mark all the votes as changeable. I would guess that this would either involve an update on a table of votes or adding a column for last edit time which is not bypassed by the grace period. I realize that this may be an entirely non-trivial change, but unless the non-posting of edits is somehow changed to make sure the edit was trivial it seems this is necessary. Why is the Principle of Superposition true in EM? Does it hold more generally? In the theory of electromagnetism (EM), why is the principle of superposition true? Can we read it off from Maxwell's equations directly?  Does it have any limit of applicability or is it a fundamental property of nature? Photoshop CC 2019: Pixelated Brush Stroke For some reasons my brush stroke suddenly looks like this:     As the picture showed, the edges are jagged and pixelated. It doesn't happen before and it's just one of the built-in inking brush.  I know there are a lot of similar questions here but please don't mark this as duplicate. I double checked all the thing the other answers suggested: It's brush tool, not pencil, and my mode of brush and layer is Normal, not Dissolve. It's pixelated even if I draw with mouse so it's not tablet driver issue. I disabled GPU render but nothing changed. How do I fix this? Just like you can see in the screenshot above, sometimes the clock &amp; date won't show up on boot. I have to log off to make it appear again.   Is that because I have a custom-time format in dconf editor ( %a, %d. %h  %H:%M ) ? How do I select all but two types of entities in Minecraft with the type selector? How do you know when to wean? What signs can a baby show to indicate he/she is ready for weaning?  What does a parent look for to determine the right timing for this for baby, mom and family? Would it be wrong to copy-paste questions from Quora? How many levels are there for Steam Trading Card badges? With the new Steam Trading Cards, I decided to craft the badge for CS:GO. I got this:    I then noticed that this is only a level 1 badge, and there was a level 2 badge to get. So I crafted it too:    Now it says there's a level 3 badge to get next. How many levels are there in total?
