If water has a boiling point of ~100 degrees C, why does it evaporate at room temperature? |
- If water has a boiling point of ~100 degrees C, why does it evaporate at room temperature?
- Would single stage rockets be achievable on Mars?
- Theoretically, how many bits of information make up our universe?
- Why are electrical monopoles possible but magnetic and gravitational ones aren't?
- Can the spot of a laser pointer move faster than light?
- if fusion in stars that go supernovae stops at iron, from where did we get heavier elements here on earth??
- If I randomly 'observe' a photon (I sometimes do, sometimes not) and then run a double slit experiment will I be able to determine if the photon has been observed or not by whether it forms an interference pattern?
- Does the effectiveness of evaporative cooling decrease as the surrounding temperature increases?
- Now that we can detect gravitational waves, will there be events we can observe through both gravity and regular astronomy?

| Would single stage rockets be achievable on Mars? Posted: 25 Mar 2016 08:36 PM PDT With its decreased gravity would single stage rockets that go from the Martian surface to Martian orbit or even interplanetary space be achievable with already existing technology? [link] [comments]  |
| Theoretically, how many bits of information make up our universe? Posted: 25 Mar 2016 07:28 PM PDT I was wondering about this in relation to a simulation. If there was a simulation on the scale of our universe, something as complex and as large, in terms of actual bits, how many would this simulation have/need? I dont know if this is the proper way to put this question, but hopefully someone understand. Is this is even possible to estimate? Thanks! [link] [comments]  |
| Why are electrical monopoles possible but magnetic and gravitational ones aren't? Posted: 25 Mar 2016 08:44 AM PDT Specifically, in simple terms, what is it about the mathematics of the Maxwell equations that says a positive or negative charge can exist but a magnetic one can't? Is there similar maths that says why gravitational monopoles don't exist? [link] [comments]  |
| Can the spot of a laser pointer move faster than light? Posted: 26 Mar 2016 06:58 AM PDT Assuming I am standing far enough from a very long wall and have a strong laser pointer, I can make the dot of the laser pointer move fairly quickly. Is there anything stopping me from moving the dot faster than the speed of light? [link] [comments]  |

| Posted: 25 Mar 2016 08:46 AM PDT I am quite new to quantum mechanics and this bit just baffles me and I feel that I am misunderstanding this concept in the double slit experiment. Any help would be appreciated! :) [link] [comments]  |
| Does the effectiveness of evaporative cooling decrease as the surrounding temperature increases? Posted: 25 Mar 2016 07:07 PM PDT I understand that when we sweat, the sweat evaporating off of our skin cools us down. However, if the surrounding temperature increases, wouldn't the water take less energy from your skin, and more from the hot air around you? Wouldn't that make it take less energy and cool you down less? [link] [comments]  |
