| Posted: 03 Jul 2017 09:27 AM PDT I actually thought of this after I sprayed disinfectant on my two year old son's hand. While his hands were slightly wet still, I rubbed my hands on his to get a little disinfectant on my hands. Did I actually help clean my hands a little, or did all the germs on my hand just go onto his? [link] [comments]  |

| How can source-shifted Zeeman effect be used to isolate a sample in absorbance spectroscopy? Posted: 03 Jul 2017 04:42 PM PDT As I understand it, the Zeeman effect is the principle of splitting a radiation beam into multiple polarized spectral lines for the purposes of error reduction in spectroscopy (by separating absorbance from background matter from absorbance due to the sample). I understand how to use this technique when the magnetic field is applied to the sample (analyte-shifted), as the free atoms of the sample alone are polarized and interact with polarized light (from lens) by either completely absorbing the light or completely transmitting it, while the background doesnt really change its pattern of absorbance no matter how the incoming light is polarized. One can then see how the absorbance changes just from the sample interacting with the light. What I don't understand is how to draw any meaningful conclusions from SOURCE-shifted background correction. In this method, the magnetic field is applied to the light (radiation) source and splits the beam into 3 polarized segments(pi, and +/-sigma) that then interact with the sample. As I understand the sigma components are only absorbed by the background, and the pi component is absorbed by both background and the sample. But how does this help with isolating the sample from the background? Thanks for thoughts on this subject. [link] [comments]  |

| What would happen if the poles switched? Posted: 03 Jul 2017 07:35 AM PDT In my geology class the prof explained that every couple of years the magnetic poles of the earth switch and begin going the other way and two questions popped into my mind: 1) does this really happen? 2) would this not be a catastrophic event if they flipped?

| How does 911 call your local police station? Posted: 03 Jul 2017 12:17 PM PDT Since all police stations in the U.S.A. have the same number, how does it always direct you to your local station? [link] [comments]  |
| Posted: 03 Jul 2017 08:11 AM PDT I'm curious how organisms "learned" how to self-replicate DNA and to synthesize proteins. Did organisms steal it from "RNA/DNA masters" like single celled life like Bacteria and viruses? [link] [comments]  |
| Posted: 03 Jul 2017 07:28 AM PDT Here is an exact quote: "According to the law of entropy, disorganization in the universe as a whole is always increasing. The law of entropy is powerful evidence for special Creation because spontaneous change, as suggested by evolution to account for the origin of life, is always in the direction of disorder. Our universe and life on Earth could not have evolved from a disordered, chaotic beginning to its present highly ordered state by chance." [link] [comments]  |
| Is there an enzyme that can deaminate cytosine, adenine, and guanine? Posted: 03 Jul 2017 09:16 AM PDT There are enzymes that exist to deaminate each of the above nucleobases, however I am curious if there is a more 'general' deaminase that can operate on two or more of them? [link] [comments]  |

| Are two objects with the same mass and different volumes going to show different weights on Earth? Posted: 03 Jul 2017 04:52 PM PDT my question is related to boyancy and if it exists on the atmosphere. I know the air is a fluid, but i have never seen anyone take on account that effect, so maybe it doesn't happen, idk, please help because knowing the answer will help me win a debate!!

| How did the tiles on the space shuttle work? Posted: 03 Jul 2017 10:18 AM PDT This came up while hanging out with some friends. I had read something that said it was because the tiles had low heat capacity, whereas another friend said it was only because of the low conductivity and that they actually had a very high heat capacity. I haven't really been able to find anything conclusive, although low conductivity definitely seems to be consistently agreed upon - heat capacity, or any other specification, doesn't seem to be explained. Anyone care to help clarify? [link] [comments]  |
