| Is this room more than 3 dimensional? Posted: 01 Aug 2017 03:52 AM PDT I watched this video here. I think this room has more than 3 dimensions, because its deforming the whole time, it has an extra property. Isnt the deformation of the room a dimension on its own Is it even possible to picture a 4 dimensional room? And is yes, can someone link it to me please? [link] [comments]  |

| Why does surface tension occur? Posted: 31 Jul 2017 11:49 PM PDT Also, what properties of a liquid (and other) make it stronger/weaker? [link] [comments]  |
| What purpose does chilling the instruments of a telescope serve? Posted: 01 Aug 2017 03:09 AM PDT Let me preface this with I have no formal education in advanced physics or engineering or astronomy or anything relative to this question/questions. My background is in biology focusing on zoology, so please forgive me if I use incorrect terminology in relation to measurements or any other lingual blunders I may commit. OK, so I know I'm way behind on this one, but I've only just started looking into it. My question is about the Lucifer Telescope. Why is it necessary to chill the instruments to about -351 ℉ (I'm American and this unit of measurement for temperature is what's most comfortable for me in terms of comprehension. I'm sorry) to make near infrared observations? What is the relationship between the temperature of the instrument, the temperature of the galaxy/universe (I guess -455℉), and the ability to observe near infrared wavelengths? Is the telescope used to search within different wavelengths? Or is none of this even a thing and they're just chilled because it is a very high powered telescope requiring a lot of cooling? Again, I apologize if these questions are gibberish, just trying to find the right way to word this with such limited knowledge of proper terminology to convey what I'm asking has been exceedingly difficult. Thank you. [link] [comments]  |
| Posted: 01 Aug 2017 04:43 AM PDT Hello guys, I just wanted to ask you if somebody could give me very basic (layman) explanation about one question. If for example you did an experiment on yourself where you tried a drug to see if it helps you with your condition, you took it 100.000 times but it only helped you 3 times. What conclusion can you draw from this? Is the result statistically not significant and therefore the hypothesis that a drug helps you can be rejected (so you can conclude that this drug doesn't help you). I know this is a very lame example, but try to give me an explanation for this particular scenario. It seems logical for me to conclude that a drug doesn't help, but I want to see it backed up by science. Thanks in advance! [link] [comments]  |

| Why do pineapples contain Bromelain? Posted: 31 Jul 2017 09:52 PM PDT I've seen a lot of articles talking about this meat digesting enzyme, bromelain, that the pineapple is unique for, but none of those articles explain why would a fruit need to digest meat. [link] [comments]  |
| Do animals besides humans have eyes that become nearsighted/farsighted or have astigmatism? Posted: 31 Jul 2017 09:42 AM PDT I assume they do because they develop other eye ailments like cataracts, but how do you tell if your dog is near sighted and needs glasses? The glasses part is a joke. [link] [comments]  |
| Why do different species have different lifespan? Posted: 31 Jul 2017 09:11 PM PDT ^ For example: Dogs have an average lifespan of 10-13 years; Sea Turtles have 80 years lifespan whilst humans have est. 30-50 years lifespan(without medicine). Why are they different? Is it because different species have evolved differently and our body cells are 'programmed' to die/weaken at a certain point in our life? If so, was/is/would there be a species that would evolved in a certain way to be 'programmed' with a very long/infinite body cells' lifespan? P.s: sorry if I got some facts wrong or sound ignorant, I have no idea what I am talking about(hence asking this subreddit). [link] [comments]  |

| What will be the fate of the outer planets when sun enters and exits its red giant phase? Posted: 01 Aug 2017 02:03 AM PDT Whenever discussing the end of the sun the fate of the inner planets are frequently mentioned, but what of the outer planets? [link] [comments]  |
| Does climate change effect the occurrence of different cloud types? Posted: 31 Jul 2017 11:19 AM PDT Here in Europe the weather is said to become more extreme regarding storms and rain. Does this effect the types of clouds we see in the sky? Like, types that are somewhat "extinct" or will become so? [link] [comments]  |
| Why are there no neutrons in a hydrogen nucleus? Posted: 31 Jul 2017 09:58 AM PDT I know deuterium and tritium exist, I want to know specifically why the most common form of hydrogen has no neutrons. [link] [comments]  |

| How does one find the activation threshold of a diode? Posted: 31 Jul 2017 04:45 PM PDT I've been tinkering with some electrical circuits as inspired by my physics class and while graphing some different kinds of diodes under rising voltage, I noticed the before they come a mostly constant resistance they a sometimes slow, sometimes fast ramp up, looking a lot like an exponentional function. What causes this behaviour, when in theory they should just have 1 activation voltage? If I wanted to find the specific voltage myself, do I simply take the point with the lowest amount of current, or do I compensate for the ramp up somehow? I feel this is tied to my imperfect understanding of what exactly a semiconductor is [link] [comments]  |

| How do orbital mechanics and our meteor showers work? Posted: 31 Jul 2017 09:47 AM PDT Searching online I was seeing how meteor showers form and if there are any maps with orbit paths and why we have these showers seemingly at the same time each year. [link] [comments]  |
