| What is the evolutionary background behind Temperature Dependent Sex Determination? Posted: 06 Dec 2015 07:44 AM PST I understand that this phenomenon allows for groups of a single sex to be produced depending on the ambient temperature. But I'm still confused as to how this trait evolved in the first place and why it is restricted to mostly reptiles. Also, why is the TSD pattern in turtles the opposite from crocodiles and lizards?

| Is it possible to view the past? Posted: 07 Dec 2015 05:01 AM PST For instance, an event on earth that took place in the 1950's? I'm aware it's technically possible to view the past everyday when we look at stars. However, I'm referring more to time travel without interacting, only observing. In this case, the people from the past would not be able to see or hear the observer and we could not change the course of events. So basically, would it be theoretically possible but not plausible? On the other hand, if it were possible, how would we likely achieve doing this? [link] [17 comments]  |
| How is this floating astronaut able to turn in place with no reaction forces? Posted: 07 Dec 2015 02:36 AM PST I've just seen this gif on /r/space (thread) that illustrates how helpless an astronaut is when away from walls and with little velocity. That makes perfect sense, conservation of linear momentum and all that. However, I can't explain how he's still able to turn in place at will. And quite easily too! Shouldn't conservation of angular momentum prevent it? Rotating any body part should turn the rest of the body in the other direction, leaving the 'average' orientation the same, no?

| Posted: 07 Dec 2015 07:07 AM PST I'm wondering, is an open interval on R considered a partially ordered set (and also totally ordered), and in this case I'd argue that the set has no maximal point, as the minimal upper bound is not included in the set. What am i misinterpreting? [link] [2 comments]  |
| Why does the ball in this gif go in the direction it does? Posted: 06 Dec 2015 08:19 AM PST Here: http://i.imgur.com/KuayNFt.gifv I know the bernoulli's theorem, that where the speed is high the pressure is low and vice versa. So here when the guy spins the ball inwardly, the speed of air on the near side is higher and so the pressure should be lesser. This means that the ball must move backward,i.e. opposite to the direction it moved in. [link] [32 comments]  |
| Can photons colide? And if so, what is the outcome? Posted: 06 Dec 2015 04:23 PM PST Photons have the properties of waves and of particles. So I imagine some sort of interaction takes place when two or more meet. I am curious as to what actualy happens. [link] [13 comments]  |
| Is extremism considered as mental disorder ? Posted: 06 Dec 2015 08:15 PM PST In any kinds or any forms. Can it be a symptom of something ? If so, is there a treatment ? I looked in DSM, but didn't found anything reliable. Thanks ! [link] [3 comments]  |
| Can you proof that theres a series, which only produces primes? Posted: 07 Dec 2015 06:39 AM PST I mean you can proof that there are infinite primes, but can you consistenly list primes in a series? [link] [1 comment]  |
| Why do some people need more sleep than others? Posted: 06 Dec 2015 10:22 AM PST IE: My nurse friend can go and work a 12 hour shift and then go out for drinks afterwards on a regular basis without any problem. On the other hand, if I get anything less than 6 hours of sleep the night before, I struggle miserably to function properly throughout my regular 8 hour shift. What gives? [link] [3 comments]  |

| How is Planck time, length, temperature, etc. determined? Posted: 06 Dec 2015 11:37 AM PST Because as far as I know the measurements are way way beyond what people can do or measure. How do people know the specific measurement when it is way too small to be measured? [link] [7 comments]  |
| How do distributions of intelligence compare to distributions of income? Posted: 06 Dec 2015 08:50 AM PST I was thinking that intelligence is a bell curve while income is a long tail, as they are generally presented, but the axis are different. The bell curve has the measured characteristic (IQ) on the x vs. quantity of subjects on the y. The long tail has the measured characteristic (income) on the y vs ordinal ranking (effectively) of individual subjects on the x. How do they compare when presented similarly? Edit: fixed mistakes and clarity. Edit: added pic links [link] [9 comments]  |
| Why are there three color charges instead of two? Posted: 06 Dec 2015 09:45 PM PST I know that there are three color charges (r,g,b) but I'm told that quarks can only exist in groups where the charges add up to white. If there were only two dimensions of color charge, with rgb being points on a hexagon and their anti-counterparts cmy being the opposite points, then a sum of all three or a combination of two opposites would always equal to zero Is there a difference in the strong force between red-green-blue and red-antired combinations?

| Does over-consumption of fiber reduce hormone production due to cholesterol removal? Posted: 06 Dec 2015 05:30 PM PST Hello AskScience, I am in a Community Health Perspectives class, and we are learning about Atherosclerosis. My professor says that built up cholesterol in the arteries can be removed (not entirely but still) by consumption of fiber, which sticks to the particles and carries them out. He also says that cholesterol is a good thing, and that it produces lots of hormones your body needs, including all of your sex hormones. My question is, if you consumed enough fiber, could you remove enough cholesterol that you noticeably stop producing enough hormones? Like, if I had Grape Nuts and a loaf of whole wheat bread every morning could my libido theoretically drop? Thank you. [link] [comment]  |

| Just how unsolvable is the Halting Problem? Where are the limits? Posted: 06 Dec 2015 09:56 AM PST Let me elaborate - I am aware that HP is undecidable, that is, there is no universal algorithm to decide, for any given Turing machine M and any given input w, whether M will eventually halt after being given input w. However, there clearly are some machines and some inputs you can decide HP for. What I'm interested in - where do these limits lie? More specifically:
I'm asking mostly in a theoretical sense, but I will also welcome more practically oriented answers. [link] [11 comments]  |
