What is the standard/recommended font to use in papers? I looked around but did not find that anyone has asked this before, but what are the fonts that are standard/recommended while writing academic reports/papers? past simple or present perfect Let $f(x)\in C^2:[0,1]\rightarrow\mathbb{R}$ satisfy $f(0)=0,f(1)=1,f'(0)=f'(1)=0$, prove that: $$\max_{x\in[0,1]}|f''(x)|\ge4$$  By using Taylor series I can prove that $\max_{x\in[0,1]}|f''(x)|\ge2$, but I cannot go further. Joda Time: How to get dates of weekdays on some date interval? Finding package name of installed software Since I have not been able to open Dash Home in 12.04.4 see , I am hoping for a work-around. Is there another convenient way to open apps/programs without having to search through folders? Is this question clear enough? For example, I just installed Kile (publishing program) from the Software Center, but I can't find a link/tile/icon/shortcut to open it. Thanks, to whomever can help. Do I have to use “do” in any “wh-” question? I'm making a map where I want players to be able to choose there kits/classes. The problem I'm having with it though is giving players already enchanted Tools/Armour/Weapons.  I'm not sure if you can use the /give [player] [item] [amount] because you'll have to use the whole {} thing and I'm not sure how to make enchanted Tools/Armour/Weapons using that.  Can anyone help? We know  speedup brute-force attacks two times faster in block ciphers (e.g brute-forcing 128-bit keys take $2^{64}$ operations, not $2^{128}$). That explains why we are using 256-bit keys to encrypt top secrets. But  on AES shows brute-forcing AES-256 take $2^{100}$ operations. Does this attack work with Grover's search to make AES cipher quantum unresistant? Word for person who looks for flattery What is the Coandă effect? How is it defined, and what causes it? Can anybody explain to me the  well? I am finding that many definitions and explanations conflict.  I am particularly confused about the following points regarding the Coandă effect:   whether the Coandă effect is the same as normal boundary layer attachment to a surface whether the Coandă effect is only defined for convex surfaces over which a jet (of the same state as the surrounding fluid) is tangentially blown what causes the Coandă effect: the jet entraining the ambient fluid or a balance of pressure and centrifugal forces, or something else? sed delete option change of delimiter Integral Representation of the Zeta Function: $\zeta(s)=\frac1{\Gamma(s)}\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$ How does one get from this $$\zeta(s)=\sum_{k=1}^{\infty}\frac1{k^s}$$ to the integral representation $$\zeta(s)=\frac1{\Gamma(s)}\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$ of the Riemann Zeta function?  I can see that it can be rewritten as  $$\Gamma(s)\zeta(s)=\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$ and the Gamma function as an integral yields  $$\zeta(s)\int_{0}^\infty \frac{x^{s-1}}{e^x}dx=\int_{0}^\infty \frac{x^{s-1}}{e^x-1}dx$$  But this approach does not work as the right integral does not converge.  So how does one go from the summation to the integral representation? When using the serial console of my system I always end up with $COLUMNS=80 and $LINES=24.  While I can change these variables manually it is somewhat annoying to do this any time when the client side terminal window has been resized.  Usually I'm connecting to the console using screen /dev/mytty baudrate.  Changing the $TERM environment variable to "screen" or "xterm" does not help.  Will I need to call getty with some of those instead of vt100?  Needless to say that all of this works fine, when I connect to the same machine using ssh. $y_{2n}, y_{2n+1}$ and $y_{3n}$ all converge. What can we say about the sequence $ y_n$? My friend and I are currently debating the following question:      Let $y_n$ be a sequence in a metric space and assume that the subsequences    $y_{2n}$, $y_{2n + 1}$, and $y_{3n}$ all converge. What can we say about the sequence $y_n$?    To me it seems that all the subsequences will converge to a limit say $y$. Then any term in the original sequence will be in one of these subsequences, it follows that the entire sequence $y_n$ converges to $y$.  I let $\varepsilon &gt; 0$. Since $y_{2n}$ converges to $y$ there exists an index $2N$ such that $d(y_{2n},y) &lt; \varepsilon$ for $2n \geq 2N$, and since $(y_{2n+1})$ converges to $y$ there exists $2M + 1$ such that $d(y_{2n+1}, y) &lt; \varepsilon$ for $2n + 1 \geq 2M + 1$.  Let $m \geq \max\{2N,2M+1\}$. If  $m$ is even, since $m\geq 2N$ we have $d(y_m,y)&lt;\varepsilon$; if $m$ is odd, since $m\geq 2M+1$ we have $d(y_m,y)&lt;\varepsilon$. Thus $d(y_m,y)&lt;\varepsilon$ for any $m \geq \max\{2N,2M+1\}$, and we conclude that $(y_n)$ converges to $y$.   However, my friend does not think that this is completely correct because I didn't use the $y_{3n}$ in the proof. I think he is right, that I do in fact need it, but I am unsure of how to add it in. All in all, I think that since any term in the original sequence will be in one of these subsequences, it follows that the entire sequence $(y_n)$ converges to $y$.  $2n+1$ covers all the odd terms and $2n$ converse all the even terms, so is $3n$ even needed? I would like to use it since the proof has it in the question, but I am unsure of what to do. Could someone kindly help me construct this proof in a better manner,and is my line of thinking correct? Thank you! How do I remove 'Places' entries from the Nautilus sidebar? I have an application running on node and using the mongodb library to establish connection and closing it. But the problem is, from the mongo serverStatus() command i can see that there is still 2k+ current connections still available.  &gt; db.serverStatus().connections { "current" : 2993, "available" : 835867, "totalCreated" : 220841 }   and most of it are having the active: false status.  My questions is, is there a way for me to force close these idle connections which after some time will affect my application with an timeout error.  I tried using the killOp() command but these only works if there is still opid value listed in these idle connections.  Appreciate some feedback on how can handle this kind of situations. What does really attracts a water stream to a charged object? I saw  by  and I was not 100% sure about the third phenomena, a statically charged object attracting a stream of water, especially because he explicitly mentioned that it is not due to the  of the water. A week later he uploaded an  all five phenomena and he says it is because of repelled equally charged ions, back up the water flow, such that the water actually falling along the charged object would be oppositely charged and therefore attracted. Here is a still image from the video illustrating this:    However this explanation seems strange to me, since this would mean that this way you could build up a charge in the water which has exited the tap (as well as in the water inside the tap as well). Therefore it should get harder to push those ions back over time, and therefore there also would be a decrease in the attraction of the water (assuming there is no other way to discharge it). I have tried a simple similar experiment, where I catched the water leaving the tap in an insulated bowl, but I did not notice a decrease in attraction.  There a couple of reasons why my experiment does not rule out his theory:   I was holding the charged (plastic) object by hand, which caused that its distance to the water stream varied, making it difficult to observe a decrease in attraction. I only conducted my experiment for roughly 30 seconds, which might be enough time for a opposite charge to build up.   The reason that he mentioned why permittivity can't cause this phenomena is because the electric field would be homogeneous and therefore the attractive and repulsive force of both dipoles of a water molecule would cancel out. However the electric field would only be homogeneous if the charged object would be an infinitely large plate, which it isn't. Thus water molecules would be attracted to the charged object. In order to make the permittivity theory more plausible I thought of maybe doing a order of magnitude calculation to see if it could generate a large enough force would be able the water stream by the observed amount. However I do not know what a good guess would be for variables such as the amount charge on the charged object and how the electric field would fall off over distance.   So, my question is whether his theory is really correct, or if the permittivity of the water can cause it. Atmospheric pressure In FBD doubt Let us say I have a beaker floating in a water tank. Suddenly I put some water in the beaker also. The figure here shows the exact situation   Now I want to draw the FBD of the beaker. I am somehow confused with the role of the atmospheric pressure in drawing the FBD. I thought of two ways of drawing this and I am just unable to figure out which one is right.    Here since the beaker is floating an $F_{buoyant}$ is there in the upward direction which the net mass (beaker+water in beaker) would put its weight downward.  But while solving one question I came to know that total force that a liquid exerts on the bottom of the container is $P_0+m_{liquid}g$ ($P_0$ is the atmospheric pressure). So should the downward force on the beaker be $(M_{beaker}+M_{water in beaker})g+P_0 S$ (S being the base area of the beaker) as in the second diagram down here.    Here the $P_0S$ due to atmospher on the tube gets cancelled by the $P_0S$ exerted by the water in tank on the tube. But what about the $P_0S$ from the water present in the tube? Do the FBD's apply like the one in the new image? How can I find the codes related to a function in GAP? When I use "??" in front of the name of function there is no help, so I want to find the code of function among packages. Is Myopia Reversible/Curable?
