- During the winter, humans are known to track animals via their footprints in the snow, as we do not posses the same olfactory capabilities as say a wolf. Are there any other animals which have been observed tracking animals by means of visual cues?
- If I have two blankets of different materials, does the total insulation change depending on how I layer them?
- Were there any islands on the "back" side of earth during the time of Panthalassa and Pangaea?
- When you grow and your birthmark stretches, how do the new skin cells know to be discolored?
- Why does light travel a longer distance through different medium?
- What causes medication stored outside its ideal temperature range to go bad?
- Given sufficient computing power, how accurately could we theoretically predict how an organism would look and act based solely on a genome?
- Why are particle accelerators like the Large Hadron Collider in Europe built underground?
- How has the understanding of exoplanets changed since the first were detected in 1988?
- How strong are the magnetic fields of stars?
- How much energy does a surge protector take up, considering that it's not technically an appliance but still draws power? Also, if I push the switch to off, will it still consume energy and show up on my electric bill?
- While forging metal, what would happen to the metal if you introduced high frequency vibrations to the metal while it's still in its liquid form, all the way until its cooled off? Would the characteristics of said metal change?
- Is it possible for humans to undergo a slower rate of development in puberty?
- I have heard that CO2 is a green house gas as it locks heat in. How does it lock heat in on the atomic level?
- How come we aren't effected by how fast the earth is spinning?
- Why are some SI units like the ampere, sievert and farad so large?
- Why is it so hard to develop new antibiotics?
- When it's said that "a photon can be both a wave and particle at the same time", are the waves in the photon field from QFT?
- Can stable baryonic matter other than protons and neutrons exist?
- Do scarecrows actually work on birds, or is it obvious to them that those are just lifeless pieces of cloth or other material?
- What are the minimum number of instructions a CPU would need to support to be Turing Complete?

| Posted: 07 Jul 2017 09:07 PM PDT for instance, I have a cotton sheet and a polyester blanket. Would having one on top trap heat more effectively than the other way around? [link] [comments]  |
| Were there any islands on the "back" side of earth during the time of Panthalassa and Pangaea? Posted: 07 Jul 2017 03:56 PM PDT The Pacific have have quite many islands in the middle of nowhere, and I assume that remote islands were not impossible during the time of Pangaea. Are there any known Hawaiis of Panthalassa back in the day? If so, is anything known about the plant and animal life there? [link] [comments]  |
| When you grow and your birthmark stretches, how do the new skin cells know to be discolored? Posted: 07 Jul 2017 03:57 PM PDT As you grow or get fat, your birthmark stretches. As it stretches, the boundary of the birthmark grows, and it gets filled in with new discolored skin. This doesn't seem to happen with moles for example. How exactly do discolored birthmarks expand?

| Why does light travel a longer distance through different medium? Posted: 07 Jul 2017 12:25 PM PDT I learnt that light doesn't actually change its speed in a medium that makes it seem like it slows down, instead it only makes it travel a longer route? How does it do that? and why? [link] [comments]  |

| Why are particle accelerators like the Large Hadron Collider in Europe built underground? Posted: 07 Jul 2017 04:16 PM PDT I imagine that particle accelerators would be a lot cheaper and easier to build if they were above ground. [link] [comments]  |

| How strong are the magnetic fields of stars? Posted: 07 Jul 2017 08:30 PM PDT In terms of Tesla (I think that's the correct measurement), how strong are the magnetic fields of stars? Neutron stars tend to have very strong magnetic fields, but what about other star types such as main sequence stars of varying masses? [link] [comments]  |
| Posted: 07 Jul 2017 02:29 PM PDT Are there actually any benefits to using a surge protector other than having more outlets and protecting against a blackout? Also, if I leave my surge protector plugged in with my PC plugged into it but the PC is powered off, will energy consumption be the same or more as opposed to not using the surge protector at all and opting to having a turned off PC in a wall outlet instead?

| Is it possible for humans to undergo a slower rate of development in puberty? Posted: 07 Jul 2017 08:56 PM PDT Sorry not sure if right place to post. Just to be clear I'm not talking about being a 'late bloomer' where an individual hits puberty at a later age but instead an individual who may hit puberty at a similar time to others but undergo changes associated with puberty at a slower rate.

| How come we aren't effected by how fast the earth is spinning? Posted: 07 Jul 2017 07:44 PM PDT It seems like if a ball is spinning, something aboard it would fly off of it. Is the gravity of Earth strong enough to pull us back? So if the earth were to stop spinning gravity would get stronger? [link] [comments]  |
| Why are some SI units like the ampere, sievert and farad so large? Posted: 07 Jul 2017 01:38 PM PDT Sorry if this is a silly question. It seems like some of the SI units are incredibly large. [link] [comments]  |
| Why is it so hard to develop new antibiotics? Posted: 07 Jul 2017 07:23 PM PDT News about a gonorrhea superbug kind of freaked me out. And as far as I know humanity hasn't developed new antibiotics in over 25 years. [link] [comments]  |
| Posted: 07 Jul 2017 02:35 PM PDT So in QFT, a photon would be a disturbance in the photon field. Would these disturbances create the interference patterns that create the quantum-mechanic effects that we attribute to "the wave-like nature" of things like photons in e.g. the Double-Slit experiment? How sure are we that QFT is actually correct, and wouldn't it contradict the idea of the String Theories of each particle being the same basic object but vibrating in different ways (I may be chatting shit with that description, or in total)?

| Can stable baryonic matter other than protons and neutrons exist? Posted: 07 Jul 2017 12:26 PM PDT The recent CERN announcement where they verified the existence of yet another composite particle as predicted by the standard model had me thinking. Is there any possible configuration of quarks, other than the combination that results in protons and neutrons, that gives you stable (lets say half life > 1 second) matter under standard conditions (Earth-like temperatures/pressures)? If not, why not? Another question in a similar vein: Is it possible (according to the known laws of physics, i.e. standard model) for there to be solid, as in, interacts electromagnetically with normal stuff, non-baryonic matter? I'm picturing something like a glob of gluons or hard light. [link] [comments]  |
