| Discussion: SmarterEveryDay's Newest YouTube Video On Tesla Coil Guns! Posted: 01 Dec 2016 08:46 AM PST Everyone loves Tesla coils, and that includes Destin (/u/MrPennyWhistle) from SmarterEveryDay and Cameron (/u/TeslaUniverse) from www.tesluniverse.com. In Destin's new video, they go as far as building a handheld Tesla coil gun, filming their experiments with his high speed camera. Destin and Cameron, as well as our physics and engineering panelists, will be around throughout the day to answer your questions about all things Tesla coily! [link] [comments]  |

| What about an actively burning star prevents its mass causing it to collapse in on itself? Posted: 02 Dec 2016 06:16 AM PST Was wondering about this last night at the Paramount Science Summit featuring Michio Kaku, Brian Greene, and S. James Gates Jr. When a star of sufficient mass dies it collapses in on itself to form a black hole (or other things). What prevents this from happening while the star is still burning?

| What are some things that could go wrong for a bird in a mass migration? Posted: 01 Dec 2016 06:55 PM PST Aviation is always having to deal with some crazy things, so I was wondering how hard flying was for actual birds(in flocks, doing mass migration). Do they ever get hit by a storm and the whole flock is killed? Birds can get lost from the flock, and if they do how likely are for them to survive in those circumstances? [link] [comments]  |
| Is there a reason Beta Minus decay emits an antineutrino but Beta Plus emits a neutrino? Posted: 01 Dec 2016 06:31 PM PST I am asking because I think it is curious that when an electron, matter, is released in the decay an antineutrino, antimatter, is released, but it goes the opposite way for a positron.

| Posted: 01 Dec 2016 02:17 PM PST I am trying to learn more about the origins of consciousness, but I am confused as to what most scientists even refer to when they talk about consciousness. Is it simply the subjective experience of perceiving the world, or does it only refer to the ability to be self aware. And if it is the latter, then would animals that are not self aware but still have a subjective experience of perceiving the world, be considered not conscious? [link] [comments]  |
| If the arteries have pressure and veins do not, then why is the [jugular] seen as the deadly vein? Posted: 01 Dec 2016 03:25 PM PST okay, so i may seem kind of ignorant here... but for some reason it isn't making sense in my brain. If the arteries have high pressure and the veins just have the check valves in them, wouldn't that mean it'd be "more deadly" to cut the left or right subclavian or brachiocephalic instead of the jugular vein? I feel like you hear about people whenever they have their neck cut (eg. hockey player took a skate to the jugular vein) it's always the jugular.. sorry this question doesn't make much sense.

| Why does the Sun bypass several elements in its composition on its way to the Iron Peak? Posted: 01 Dec 2016 03:35 PM PST It seems as though according to this only 10 elements are found in the Sun whereas there are 16 elements it's just passing on its way to The Iron Peak. The logical answer is that they're all there, just in super small undetectable amounts. But then why are those elements so rare? [link] [comments]  |
| Posted: 01 Dec 2016 12:42 PM PST Additionally, with the exception of cetaceans, which obviously evolved a streamlined body shape, why do these few mammals have internal testes, when most other mammals get along fine with external testes? [link] [comments]  |
| Why would obsidian lose weight after being submerged in water? Posted: 01 Dec 2016 06:03 PM PST We did a lab to measure how much water a rock absorbs. We did this by weighing the rock before and after submerging it in water. For many people obsidian lost weight, any idea why? [link] [comments]  |
| Posted: 01 Dec 2016 12:33 PM PST A couple more... -Can you create an immortalised cell line from any aggressive cancer? -For research purposes, what would an ideal immortalised cell line look like? I took a few genetics courses in college but my knowledge on the subject is still pretty basic. Nonetheless, immortal cell lines have fascinated me recently. [link] [comments]  |
| Do sea going animals ever get the bends? Posted: 01 Dec 2016 06:53 PM PST I have just started watching Planet Earth II and saw the bit about sea iguanas can hold their breath for 30 minutes and dive down to 30 meters. I don't think this would be far enough down to cause the bends, but do whales or anything else ever get this from coming up for air to fast? [link] [comments]  |
| Are there Brownian motion of solids? Posted: 01 Dec 2016 03:41 PM PST I'm currently in my second year of A-Levels (A2), if you know the education system, and I am learning Physics as one of my options. I understand that Brownian motion is the random movement of small visible particles suspended in a fluid due to collisions which much smaller, randomly moving atoms or molecules of the fluid; and that any particle above absolute zero will have constant motion as an increase in kinetic energy will result in a greater vibration of the solid around their respective equilibrium positions. The textbook I am learning from shows me the Brownian motion of gases, liquids and solids. I also know the experiments of observing the Brownian motion for both gases and liquids, but my question to my teacher was: What is the experiment to observe the Brownian motion of solids, as shown in the textbook. Is there a method of observing Brownian motion for solids or is it theoretical? [link] [comments]  |

| Nuclear particle exchange in solids? Posted: 01 Dec 2016 03:26 PM PST In solid non-radioactive material at room temperature, does any exchange of particles occur between neighboring nuclei? [link] [comments]  |
| How are white dwarfs able to maintain being a star? Posted: 01 Dec 2016 10:42 AM PST From what I understand, and please correct me if I am wrong, white dwarfs are the cores of starts left behind after they go supernova, and stars go supernova because they can't maintain fusion with heavier elements like iron. I know that the inside of a white dwarf is under a redonkulous amount of pressure and that if more stuff falls into it, it eventually becomes a black hole. My question is, since fusion reactions do not occur in white dwarfs from the way I understand it, how are they able to maintain being a star? [link] [comments]  |
| [Mathematics] What is the probability of finding a quarter from any given year? Posted: 01 Dec 2016 06:12 PM PST I have a habit of looking at the dates on quarters and trying to find years that are significant to me. My question is, if I have a handful of quarters like from a $10 roll at the bank, is finding any year just as likely as another? How many quarters would likely be from the same year (or for that matter, same decade)? [link] [comments]  |
