I'm not aware of everything that is in The Flash lore (comics, animated series, etc.) but I did watch some of it to notice that, I never saw an explanation on how he can breathe when running? By that, I mean, the faster you run, the more you would normally breathe. I understand it's either probably just omitted for the plot/because it's fiction, or maybe it's explained somewhere I overlooked. As for which instance of &quot;The Flash&quot; I'm referencing... well, I wouldn't know myself given I don't know enough of the lore (as already stated) but I guess it can be taken as a &quot;general&quot; question, rather than specific.
How do the Flashes breathe utilizing their super speed? The air pressure would be extreme. Do they run in a pressurized bubble?
Are there any age limits (formal, informal, or guidelines) that schools use when deciding to accept someone into a PhD program? I'm most curious about the upper age limits. For example, will most schools accept someone in their 40's? How about their 50's? How can Cooper communicate with his daughter before the time he went to space? cat files with directory Is there a command to show the directory/file name when cat files?  For example: assume two files f1.txt and f2.txt are under ./tmp  ./tmp/f1.txt ./tmp/f2.txt    Then when I do cat ./tmp/*.txt, only the content of files will be shown. But how to firstly show the file name, then the content?, e.g.:   (The needed command):  ./tmp/f1.txt:    This is from f1.txt  and so on  ./tmp/f1.txt:  This is from f2.txt ...   Is there a command to do it? (There seems to be no option for 'cat' to show the file names) Is it safe to knowingly buy an oversized (67-inch) suitcase? Are size limits enforced? Why is a vector space equal to its tangent space for any point? I'm self-studying Guillemin and Pollack, but I'm stuck on Problem 3 of section 2. It says that if $V$ is a vector subspace of $\mathbb{R}^N$, then $T_x(V)=V$ if $x\in V$.  If $x\in V$, then since $V$ is a manifold, there is a local parametrization $\phi: U\to V$ where $U$ is open in $\mathbb{R}^k$. Without loss of generality, we can require $\phi(0)=x$. Then $T_x(V)$ is defined to be the image of $d\phi_0$ on $\mathbb{R}^k$.   An arbitrary element of $T_x(V)$ looks like $$ d\phi_0(v)=\lim_{t\to 0}\frac{\phi(0+tv)-\phi(0)}{t}=\lim_{t\to 0}\frac{\phi(tv)-x}{t} $$  but this doesn't seem very useful to show $T_x(V)=V$. What is the right approach? How to output HTML from JSP  block? I just started learning JSP technology, and came across a wall.  How do you output HTML from a method in &lt;%! ... %> JSP declaration block?  This doesn't work:  &lt;%!  void someOutput() {     out.println("Some Output"); } %&gt; ... &lt;% someOutput(); %&gt;   Server says there's no &ldquo;out&rdquo;.  U: I do know how to rewrite code with this method returning a string, but is there a way to do this inside &lt;%! void () {  } %> ? Though it may be non-optimal, it's still interesting.

I installed Ubuntu after windows, now my windows is corrupt due to some virus and I need to reinstall it. Currently when I start my PC, grub loader comes up and I need to select Ubuntu or Windows.   I was wondering how can I install windows again and still have my Ubuntu install? Is there a way to do this?  I do not want to install Ubuntu again and lose my settings and data there.   Thanks, Ketan How long can eggs be unrefrigerated before becoming unsafe to eat? Precedence between implication and bi-implication I came across this question:  Let p, q, and r be the propositions  p : Grizzly bears have been seen in the area. q : Hiking is safe on the trail. r : Berries are ripe along the trail. Write these propositions using p, q, and r and logical connectives (including negations).     If berries are ripe along the trail, hiking is safe if and   only if grizzly bears have not been seen in the area.   I see an If r,q iff ~p where If r,q is the part "If berries are ripe along the trail, hiking is safe" and ~p is "grizzly bears have not been seen in the area"  and I came up with (r -&gt; q) &lt;-&gt; ~p  But the answer given is: r -&gt; (q &lt;-&gt; ~p)  Can someone please explain the difference in precedence? Hi this must be a basic question but I haven't seen an answer with cerbot considerations (if there are any considerations). How do I get https www to redirect to non-www instead of timing out?  The https www version of my site times out instead of redirecting to non-www, whereas all other versions (http and https non-www) work fine.  Preferably I would like to future proof so that I can renew the certs through certbot and not need to manually change the nginx config afterwards.  The nginx server config is shown below:  server {     listen 80 default_server;     listen [::]:80 default_server ipv6only=on;     server_name www.mydomain.com mydomain.com;      listen 443 ssl; # managed by Certbot     ssl_certificate &lt;path_to_cert&gt; # managed by Certbot     ssl_certificate_key &lt;path_to_key&gt;; # managed by Certbot     include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot     ssl_dhparam &lt;path_to_this&gt;      if ($scheme != "https") {         return 301 https://$host$request_uri;     } # managed by Certbot } Non-abelian group $G$ satisfying $(a \cdot b)^i=a^i \cdot b^i,$ for two consecutive integers. Given an example of a non-abelian group $G$ satisfying $(a \cdot b)^i=a^i \cdot b^i, \forall a, b \in G$ for two consecutive integers.   This is question 5 from Herstein Page 35.

We have been puzzling over where to put the submit button, on the left or the right. In researching, we noticed that many sites put buttons on the bottom right in dialogue boxes, and on the bottom left in forms.  It makes sense: in a dialogue box it seems to denote finality, being in the endpoint of the window for left–right readers; in a form, the bottom right could be in a different position relative to the rest of the form if the window is resized.  It seems to be a convention, but I don't see anyone talking about this specific phenomenon in the following questions, nor the articles referenced therein:        So, is this level of button position optimization worth it if it creates an inconsistency in button placement? Is this a good way to go? $\sum \cos$ when angles are in arithmetic progression
