| Posted: 21 Aug 2016 08:10 PM PDT Seeing as our stomach acid can deal with quite a bit, even having the ability to contribute to personal harm if the stomach isn't adequately protected, a simple organism can like bacteria can survive it and even cause harm to the host. Why is that? [link] [comments]  |

| Posted: 22 Aug 2016 07:53 AM PDT How come gamma radiation has an infinate distance but low ionisation out of the three radiation types, - alpha beta and gamma. But according to the electromagnetic spectrum gamma rays travel very little distance but high energy? This is just a question that has confused me at school in physics. Thanks [link] [comments]  |
| Why is antenna length related to signal wavelength? Posted: 22 Aug 2016 12:50 AM PDT I was looking at this picture of an antenna serving as a receiver and I don't understand the decision of antenna length. If antenna length was related to amplitude - great, makes perfect sense, make the antenna as big as the signal can get. What doesn't make sense is how it's related to wavelength, since the wave runs perpendicular. How are those two related and why is amplitude of wave not being used? [link] [comments]  |
| Does the earths magnetic strength increase the closer you get to the earths core? Posted: 22 Aug 2016 02:50 AM PDT Simply put does the earths magnetic power increase as you get closer to it like a traditional magnet. Does having an iron coin in your pocket get more attracted to the ground the further you dig towards the earths core? [link] [comments]  |

| How are we able to determine the energy of an EM wave? Posted: 22 Aug 2016 07:42 AM PDT By the energy, I more or less mean at a point in time rather than over a period of time (like how bytes are read into sound in an audio editing program). And is there a way to determine the peaks? For example, a plate above a pool of water with waves in it would only be wet where the max height of the water wave reached. I'm not sure if any of that makes any sense, but I'll try and clarify anything else if you have questions. [link] [comments]  |
| What gives rose quartz its color? Posted: 21 Aug 2016 12:22 PM PDT This is a question that has been bothering me for some time and I can't find an answer. [link] [comments]  |
| Posted: 21 Aug 2016 10:00 PM PDT I was curious because the moon, as far away as it is, is held in by the earth's gravity but because we are so much smaller I wasn't sure if it would be enough to pull us back. But I also thought that since the moon is so much further away than the ISS I wasn't sure if the sheer distance the body would have to travel would be enough for the minimal gravity to stop the body.

| Why does rapidly inverting colors make an image seem like it's moving? Posted: 21 Aug 2016 07:59 PM PDT Title. I sometimes see on Facebook gifs of an image being inverted over and over again, and it gives the illusion that the image is moving. Why is this? In [this link] I believe the bottom right is actually moving, but the rest isn't, so why does it appear to wobble? Thanks!(http://66.media.tumblr.com/f1c852d731672e0c8c4c1194b547a0eb/tumblr_o0dzqkH78k1tuaz2oo1_500.gif) [link] [comments]  |
| How does GABA(a) presynaptic depolarization lead to inhibition of transmitter release? Posted: 21 Aug 2016 01:15 PM PDT I read in a review that depolarization from GABA(a) receptors was used to inhibit neurotransmitter release by disrupting action potentials. This seemed a bit counterintuitive to me, because depolarization is a major driving force behind action potential. This is exactly what the paper said: ". . . depolarisation could affect transmitter release via an action on other ion channels at or very close to the release site: inactivation of Na + and/or Ca 2+ channels could reduce the amplitude of the action potential and decreased Ca 2+ influx would be expected to reduce the probability of exocytosis of neurotransmitter. Depolarisation could, moreover, decrease the driving force for Ca 2+ influx immediately after the action potential, further contributing to the reduction in exocytosis." Not sure if that helps, but the paper is called paper called "Presynaptic, extrasynaptic and axonal GABA A receptors in the CNS: where and why?" by Kullmann et al. 2004. Thanks in advance. :) [link] [comments]  |

| Are there any materials where the freezing point and melting point are different? Posted: 21 Aug 2016 09:52 AM PDT Like the phase change is dependent on the current phase? (Same question for boiling and sublimation.) [link] [comments]  |
| Does number of resistors in equivalent parallel resistor circuits affect heat production? Posted: 21 Aug 2016 06:58 PM PDT I'm building a resistor bank for a switch in my car that needs to be between 15-17 ohms. I have access to 50 and 100 ohm resistors (10W) and I've come up with three potential setups to achieve 16.67 ohm total resistance: (These are in parallel, by the way) 1) 100-100-100-100-100-100 2) 100-50-100-50 3) 50-50-50 Will any option produce less heat than the others? Or is there no difference? [link] [comments]  |
| Do insects, particularly cockroaches, use acid in their digestive system? Posted: 21 Aug 2016 09:52 AM PDT From what I can gather, they seem to use gizzard to grind food, and break them down with enzymes in their midgut. Is there no acid involved like larger animals do? [link] [comments]  |
| How does "dark current" in a photodiode conserve energy? Posted: 21 Aug 2016 05:39 PM PDT Photodiodes produce a tiny current when no light enters them. Where does this energy come from and why does it not eventually deplete? [link] [comments]  |

| Does anyone use factorials in their field? Posted: 21 Aug 2016 02:27 PM PDT Recently was the vicim of /u/expectedfactorialbot and my mind wandered for a bit, then I finally wondered if they have any application to anything. Flair is math but the question is open to any field of science. [link] [comments]  |
