We have all learned that the earth is getting heat up because of the CO2 and CO molecules absorbing heat. However, how is heat actually kept in those molecules. When photons heat them up, their electron gets excited and goes to a higher energy level; however, we know that atoms want to remain at a low energy state and they quickly drop down to a lower energy state (correct me if I am wrong here). If that is happening, then how can heat be actually kept in a carbon-monoxide or carbon-dioxide molecule?  Is it because during the day, they get heat up and remain heated because they require more time to get to a lower energy state?  Note: This is not a duplicate to the question given as a duplicate because the other question was addressed at why is one element able to absorb heat and not the others. This question, on the other hand, is focused towards how any element is able to absorb heat at all.
We are all told at school water vapour and carbon dioxide are the top two greenhouse gases, and that they absorb thermal infra red radiation, trap heat and warm up the Earth. My question is how do they do that? Why can't Oxygen or Nitrogen or any other gas not absorb infra red radiation as well as water vapour or CO2?
How to get Intel Dual Band Wireless-AC 3168 work on Ubuntu 16.04? C# vs Java Enum (for those new to C#) Code block is not properly formatted when placed immediately after a list item Ring of rational-coefficient power series defining entire functions I know the "textbook" estimate of the standard error of a proportion is $SE=\sqrt{\frac{p(1-p)}{n}}$, but does this hold up when the data are weighted? How do I transfer a file to my server using PuTTY? How do I get my device detected by ADB on Linux? I just got my shiny new Wileyfox Swift – and before putting it to use I want to oem unlock and root it (as I usually do with new devices ;) Trouble is, though  is enabled on the device, and a corresponding line in /etc/udev/rules.d/51-android.rules exists, the device is not seen by adb devices.  I know there are several answers scattered around this site, but they are either hard to find, just cover a specific device, or don't cover all steps I finally needed. So I take this as a chance for a canonical, device-independent question and give it a detailed answer below:  How can I get my Android device seen and used by adb on Linux? How can I download this flash game for offline play? is one of the best flash games ever.    Is there some way to download it, so that I can play it offline? Fake News Detection problem I would like to work on a project for Fake News Detection especially for Indians news which are in different languages and different formats.   Fake news as image with no or very less text Fake news on a blog site Fake news as Tweets Fake news in Hindi Fake news in the watsapp group and shared across.   Need your help on the approach. One approach I can think of is using OCR we can read the content of the post, then search those content in the google. If the news is not present in any of the famous print media then we can tag it as fake. However there can be many challenges in this. What if the print media itself gives any fake news shared by someone.  How to handle the scenario where there is no text in the image but the information shown as image is fake.  How to handle posts written in Hindi. ?  And even if we detect fake news, is there any way to make the person accountable for sharing it. ? I know it is little difficult problem to solve. But is there any work currently done by any company on this. ?  Any starting point for me to get into this domain ? What are the highest DC and AC voltages or currents that can be considered as safe? TikZ Adding Text I'm a recent convert to TikZ from xy-pic, and am still trying to get a hang for it. I see that one can add labels to the end of arrows and the like using \node. Is there a way to add an arbitrary piece of text at a given position in the text, regardless of whether there is a shape there, a line there, or nothing at all? Thanks very much for your insight. Prove or the disprove the existence of a limit of integrals Let $A \subset \mathbb{R}^2$ be the annulus defined, in polar coordinates, as  $$ A = \{ (r, \theta) \in [0, \infty) \times [0, 2\pi) : 2 \leq r \leq 3 \} \, .$$ Let $F: A \to A$, $F:(r, \theta) \mapsto (r, r \theta \text{ (mod } 2\pi))$. Let $g : A \to \mathbb{R}$ be a continuous function. Discuss the existence of the limit $$ \lim_{n \to \infty} \int_A g \circ F^{(n)}(x) \, \text{d}x \, ,$$ where $F^{(n)} = F \circ F \circ \dots \circ F$ denotes the composition of $F$ with itself $n$ times.  I cannot find a way to attack this problem. Here's what I tried: if $g \circ F^{(n)}$ converged, I think we could take the limit under the integral sign. So I tried to show the convergence of $F^{(n)}$. If it converged, then the limit function must send every point to a fixed point of $F$. So I determined the fixed points of $F$. But I don't think $F^{(n)}$ converges. Is there any problem if the last name prints first than the first name on an air ticket?

Poisson / exponential distribution Next weekend you will be participating in 12km cross country race on a mountain.The average time between  two successive wild animal sightings on the mountain is reported to be 5 minutes  (a) What is the probability that you see at least one wild animal in the 11th minute of the     race given that you will see 3 wild animals since the start of the race?  (b) What is the probability that it will take more than a quarter of a hour before you see a wild animal after ten minutes of running?  Now I have attempted (a) , but I don't know whether my thinking is correct. (b) on the other hand makes little sense to me.  My attempt:  (a)$ X~ Poisson(\frac{1}{5})$ and $Y~Exponential(\frac{1}{5})$  $Pr(X&gt;4) = Pr(X&gt;1)$  (I am thinking that this is some variation of the memoryless property)  $Pr(X&gt;1) =Pr(Y&lt;1)$  $Pr(Y&lt;1)= 1 - (e^{(\frac{-1}{5})})$  Perhaps, I was a bit to vague in my attempt of (a). So here goes my attempt of(b).From my understanding of the question , it is asking what it the probability that the time between events(in this case animal sightings) is more than 25 minutes given you have been running for ten minutes  Now from what I know the fact that you have been running ten minutes is irrelevant this is due to memory-less property of the exponential  distribution   so without further ado  I present my attempt at (b)   let $X $ be exponentially distributed random variable with $\lambda = 1/5$  then  $Pr(X &gt;15) = 1 - Pr(X &lt;= 15)$ There are two Java Web Start tags:  : x 239 : x 320   Both tags refer to the same technology  refers to  both wiki point to  all questions tagged with  clearly relate to Java Web Start   I suggest they be merged into  (which appears in the auto-complete list if one types "webstart" in the Tags box when asking a new question). How to show $\lim_{n \to \infty} \sqrt[n]{a^n+b^n}=\max \{a,b\}$? Let $a\geq 0$ and $ b\geq 0$. Prove that $\lim_{n \to \infty} \sqrt[n]{a^n+b^n}=\max \{a,b\}$.

Since the network manager is troubling me so much I want to replace it (possibly wicd orNM from ppa:volanin).  I do not know how to connect and disconnect to the network through the terminal without using network manager.  I would like a command-line way of managing the network. header and footer of the first page of every chapter It maby be weird, I want to make header and footer for every page including the first page of each chapter, how can I do this?
