| Could solar flares realistically disable all electronics on earth? Posted: 14 May 2019 06:01 AM PDT So I've read about solar flares and how they could be especially damaging to today's world, since everyday services depend on the technology we use and it has the potential to disrupt all kinds of electronics. How can a solar flare disrupt electronic appliances? Is it potentially dangerous to humans (eg. cancer)? And could one potentially wipe out all electronics on earth? And if so, what kind of damage would it cause (would all electronics need to be scrapped or would they be salvageable?) Thanks in advance [link] [comments]  |
| Posted: 14 May 2019 04:54 AM PDT I'm researching harmonic motion for a physics exam right now, and as I understand it, driving forces, amongst other things [equal/close to the natural frequency of a system, pi/2 rad out of phase with the oscillation of the system, etc] needs to be consistently periodic in order to cause resonance of a system. If the wind is just gushing one way at a certain speed, how does this induce resonance in a physical structure? [link] [comments]  |
| Are bees drawn by scent or sight? Posted: 14 May 2019 07:39 AM PDT I had no idea where to post this... Now I'd like to give you some background to why I'm asking... basically I have a phobia of bees. a real true in every sense actual PHOBIA. Meaning when bees are around me I literally blank out from fear. My whole self goes into flight mode and I end up putting myself into a way more dangerous situation trying to escape. For example accidentally running into traffic to escape a bee. I have nightmares about once a month where I wake myself up screaming over a bee. One sad day I was a passenger in the front of a car that a bumblebee flew in. In my panicked frenzy of fear I KICKED OUT THE FUCKING WINDSHIELD. This is my real life. As you can imagine due to my extreme fear of bees I have indirectly become leery of flowers. Now it's unfortunate because I think they're pretty and I like how they smell and I want to like them but I'm afraid to get too close. Also in the summer I tend to avoid perfume for fear of smelling too sweet or flowery. Now that you have the background i am asking because I want to do a hairstyle with FAKE flowers in it. Will bees be indifferent to me? Will they see the flowers and want to land on them? Do they only smell flowers? Do you think I will be safe? Thanks for reading this guys!! [link] [comments]  |

| How are Scoville heat units calculated? Posted: 13 May 2019 05:12 PM PDT I have been told that the Scoville scale is based on the concentration of capsaicin in the pepper itself. But concentration is in molarity, so how would you get from the concentration to Scoville heat units? [link] [comments]  |
| What Scientific Discoveries Proved Lord Kelvin Wrong About The Future Of Physics? Posted: 13 May 2019 12:08 PM PDT In the 1900s Lord Kelvin said "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement." I'm assuming this quote is backed up with the fact there weren't many discoveries being made and it felt like physics had been fully sussed out (I'm assuming he didn't just say this for no reason). Of course he was wrong as we have lots of unanswered questions and theories in cosmology and quantum mechanics now. But what were the precursors to this new age of physics? There was of course the Bhor-Einstein debates but what was the first observation or theory that hinted that there is a lot more that is yet to be discovered and understood? [link] [comments]  |
| What is causing the background static/white noise being heard in VHF signals? Posted: 14 May 2019 07:47 AM PDT I've been listening to this stream of LiveMeteors.com. Everyonce in a while a distinct audio is heard, but for the most part it's just white noise. Where is this white noise coming from exactly? [link] [comments]  |
| when a cell of a body dies.... What does happen with the cell? Posted: 14 May 2019 03:14 AM PDT what is happening after the dead of a cell, through apoptosis or necrosis, with the cell? Does it got just broken down and absorbed by the surrounding cells? Can someone explain this and some mechanisms behind this? (please dont mind my english skills, not native speaker) [link] [comments]  |
| How do we tell the difference between small and far away? Posted: 14 May 2019 06:54 AM PDT I don't know how simple this answer is. It may be a really silly question. But I have seen a YouTube video that shows how giant some stars are. Although they all look comparable in size from earth. So my question is what method do they use to to tell if it's really big or just really far away over such a vast distance? [link] [comments]  |

| Why does UV light cause damage to the retina? Posted: 14 May 2019 06:17 AM PDT What makes UV light sources such as the sun dangerous? What chemical process takes place when UV light enters the eye to cause damage? [link] [comments]  |
| How high a signal frequency can we create? Posted: 14 May 2019 06:13 AM PDT I want to know is it possible to make a zero point frequency and if not how high can one be made? how close can we get? [link] [comments]  |
| Briefly, how do Loop Diuretics deal with Hypertension? Posted: 14 May 2019 02:24 AM PDT Im extremely sorry if this is the wrong place to ask such a question, but I'm doing a project based on loop diuretics and for a brief introduction I wanna word it as simply as possible how Loop Diuretics deal with Arterial Hypertension. Thanks [link] [comments]  |
| Posted: 14 May 2019 06:08 AM PDT One way these people are caught is when the hospitals notice that many more patients need to be resuscitated after a particular nurse's shift. It seems to me a program should be flagging these anomalies asap. Not sure how to flair this. [link] [comments]  |

| Why did they just redefine the kilogram? Posted: 14 May 2019 05:28 AM PDT Since they were revising SI anyway, why not take the opportunity to make the gram the official base unit? [link] [comments]  |
| Why is ritalin used as a placebo in psilocybin trials? Posted: 14 May 2019 05:06 AM PDT Not sure if this falls under psychology or neuroscience, but how is ritalin considered a placebo for psilocybin? I was reading How to change your mind by Michael Pollan when I came across this little tidbit of information. [link] [comments]  |
| Can blockages of the coronary artery be reversed without surgery? Posted: 14 May 2019 04:56 AM PDT When coronary arteries become partially blocked, in the sense that there's still blood flow but there is build up in the artery, can diet and exercise help clear them? Or does diet and exercise simply prevent further blockage? [link] [comments]  |
| How do we measure the frequency of light? Posted: 14 May 2019 04:51 AM PDT Especially since the resolution might be to several decimal places and that unpolarised light might have the frequency change moment to moment. With regards to measuring the frequency of distant galaxies - to measure Redshift - how do we measure the frequency of one galaxy and not all the stuff in between and near it. For example, if there were a trillion small dust clouds in the trillions and trillions of meters (in the straight line) between us and the galaxy, the reflection, absorption and reemission of light by the dust, asteroids etc could affect the frequency. And galaxies extremely far away will blend into one since a second of arc from our measuring equipment will include quite a lot of celestial bodies (1/1296000 of all of them) And large distances in space, as I understand it, are curved due to the gravitational effects of bodies we have no idea about it (as there are an infinite number of objects with mass in very deep space) Lots of questions about this.
