| Why do those with Down syndrome have similarly shaped faces? Posted: 02 Jul 2017 10:33 AM PDT While most faces are still unique in some way, those with Down Syndrome can be recognizable due to smaller ears, flatter face, almond-shaped eyes, and flatter nose. With all of the variations of facial features, why does Down Syndrome give even those who have a different cultural background very similar facial features? [link] [comments]  |
| Is this paper correct in stating that Newtonian physics can be indeterministic? Posted: 02 Jul 2017 09:40 PM PDT In this 2008 paper PDF, the author presents an example of a situation--a ball perched at rest atop a dome--in which the laws of Newtonian physics are indeterministic, that is, the same exact initial conditions can produce more than one outcome. In this case, that the ball can either remain at rest on top of the dome, or slide off at some arbitrary radial trajectory at any time. I have been under the impression that Newtonian physics are purely deterministic (and for the only possible indeterminism in physics, one needed to appeal to quantum mechanics). So, is this paper correct in asserting that they are not? And if it is correct, why isn't this more widely known? (or is it just me?) [link] [comments]  |

| Can pollution actually alter the color of a summer sky? Posted: 02 Jul 2017 07:16 PM PDT I've lived in NYC my whole life. Sometimes the sky looks cotton candy colored and I can't see how pollution would play a role in that. [link] [comments]  |
| Why does the radio that is used for wireless communication have that distinct chatter-y sound? Posted: 02 Jul 2017 10:28 AM PDT Is it because of some special reason? Because we have crystal clear sound from our smartphones which are also wireless but those radio sounds are kinda hard to understand. Edit: Grammar [link] [comments]  |

| Are we prepared to handle a direct hit from a CME? Posted: 02 Jul 2017 04:14 PM PDT Are there procedures in place for when the Earth is hit by a coronal mass ejection? What are they? What would be the short term effects? Long term? This is coming from a guy who just learned what a CME is an hour ago. [link] [comments]  |
| Posted: 02 Jul 2017 08:11 PM PDT For example, purely hypothetical, does the average PC today even come close to supercomputers back in 1990s? [link] [comments]  |

| Why do jet engines not have bell-shaped nozzles like rocket engines? Posted: 02 Jul 2017 03:56 PM PDT I understand that a bell nozzle on a rocket engine works by redirecting all of the sideways-expanding exhaust to point downward, which increases the thrust of the engine. Obviously this logic does not apply to jet engine exhaust, but why? Jet engines use combustion as their power source, so why do engine bells not work to capture all of the hot exhaust?

| How does alpha or β+ decay effect an atoms bonding? Posted: 02 Jul 2017 09:29 PM PDT I'm curious about the general trends but I can provide a specific example if my question doesn't make sense: If I have a 89 Zr4+ ion and bond it to something, it'll form 4 bonds. The Zr will then decay via β+ emission to 90 Y, which has one fewer protons, hence the neutral atom with 4 bonds will suddenly have a negative charge and an oxidation state that doesn't typically allow for 4 bonds. What happens to the atom? Does a H+ jump in and steal the negative charge? Does the negative charge go into anti-bonding orbitals? Does the atom fly off, it's bonds broken? [link] [comments]  |

| What exactly does http/https encryption encrypt? Posted: 03 Jul 2017 04:02 AM PDT If I go on the BBC website for example, what exact data is being sent across the internet that I probably wouldn't want people seeing? Obviously the contents of the actual web page I'm going to will be sent, but what personal information (if any) would be vulnerable if I did not use http or https encryption? [link] [comments]  |

| Posted: 02 Jul 2017 11:19 PM PDT I'm sure our sun is bright enough to be seen from 4.2 light years away but when you consider that we usually create constellations from the brighter stars in our night sky, would our sun be considered bright enough to be part of one of their constellations or would it just be a tiny speck in the background?

| Do virgin photons exist? Photons that travel from other stars without touching matter? Posted: 02 Jul 2017 09:55 AM PDT Or do all photons eventually bounce off some form of matter on their travel? [link] [comments]  |
| How is determined the acceptable amount of toxic substances in food? Posted: 02 Jul 2017 05:10 PM PDT I am particularly interested in knowing if the current average lifespan is taken in consideration when it comes at fixing this level. What if the lifespan increase significantly and we start to die due to the "acceptable amount of mercury"etc in our food instead of dying at 80 like "we were supposed to"? [link] [comments]  |
| Can you shoot a gun, fatally, in space? What would happen? Posted: 02 Jul 2017 08:03 AM PDT Just a thought spanning from the USA's proposed Space Corps sixth branch of the armed forces (ignoring the coast guard), and also the eventual follow up thought of those Call of Duty missions.
My instant thought is of a slowing bullet leaving the chamber, or that it'd slow down and just float on into deep space, but hey if I knew what would happen I wouldn't r/askscience. [link] [comments]  |

| Do animals other than humans experience symptoms of pregnancy? Posted: 02 Jul 2017 08:47 PM PDT As in nausea, cravings, etc. I doubt any as similar as our human symptoms obviously. [link] [comments]  |
| Distance and diameter of the sun? Posted: 02 Jul 2017 07:54 PM PDT How do we know the sun's distance from the Earth? What's the evidence that it is so far away? How do we know the sun's diameter? Thanks scientists. [link] [comments]  |
