- My physics textbook says that small redshifts of galaxies are due to their velocities relative to us, while large redshifts would be caused by expanding space stretching wavelengths. Is it really necessary to make a distinction like this, and can redshift be explained through a particle model?
- How does infrared light heat objects up?
- Does Earth have the most varied elemental composition in the solar system?
- Can you Find new prime numbers by multiplying all of the known prime numbers and adding 1?
- Is there a 'Goldilocks zone' for planet rotation, ie, if the planet rotates too fast or too slow, does it prevent the formation of life?
- Approx. how many earths could fit in the newly discovered record breaking super-massive black hole in galaxy NGC 4889?

| Posted: 19 Feb 2016 04:34 AM PST I'm Kerry Emanuel, a Professor of Atmospheric Science at the Massachusetts Institute of Technology in Cambridge, Massachusetts. I do research on hurricanes and other types of severe weather, on climate change, and how climate change might affect severe weather. My research is mostly theoretical, but I also build computer models and occasionally participate in field experiments and build and use laboratory experiments. I have flown research aircraft into hurricanes, and wrote a book called "Divine Wind: The History and Science of Hurricanes", aimed at a general reader and covering both the science of hurricane and how they have influenced history, art, and literature. I'm Dan Cziczo, an Associate Professor in Atmospheric Chemistry at MIT interested in the interrelationship of particulate matter and cloud formation. My research utilizes laboratory and field studies to elucidate how small particles interact with water vapor to form droplets and ice crystals which are important players in the Earth's climate system. Some of my group's experiments include using small cloud chambers in the laboratory to mimic atmospheric conditions that lead to cloud formation and observing clouds in situ from remote mountaintop sites or through the use of research aircraft. More generally, my research interests include: Chemical composition of atmospheric aerosols with an emphasis on their effect on cloud formation mechanisms, Earth's radiative budget, and meteoritic debris and launch vehicle emissions in the atmosphere. This week, we started the second offering of our massively open online course (MOOC) on "Global Warming Science", which you can register for free to take at here at EdX. We think it's a great way to learn the science behind how the Earth's climate system works, and about both past and future climate changes. Best of all, you'll be taking the class with thousands of people from all over the world - from students to researchers to professionals in many different careers and from many different walks of life! Three of our doctoral students from MIT are helping to TA and will be available to help us answer any questions you might have during the course. Additionally, David McGee, an Assistant Professor in Climate Physics and Chemistry at MIT is also teaching the MOOC, but is unable to join us today (although he's happy to answer any questions you might have on the course forum!) We look forward to answering your questions about our research and our climate MOOC at 10AM EST! Ask us almost anything! EDIT - 10:10 AM (EST) - We're online answering your questions! We'll be around for about 1-1/2 - 2 hours to chat. Note that /u/kerryemanuel is indeed Professor Emanuel's real account. [link] [comments]  |

| How does infrared light heat objects up? Posted: 19 Feb 2016 02:47 AM PST I've been learning about the photoelectric effect in my physics class, and one of the formulas that I learnt was that the energy of a photon of light is given by E=hf. From this equation, ultraviolet light has more energy than infrared. So why is infrared able to heat up objects and ultraviolet not? Temperature is a measure of the average kinetic energy of an object, so wouldn't a higher energy light transfer more energy? [link] [comments]  |
| Does Earth have the most varied elemental composition in the solar system? Posted: 18 Feb 2016 08:45 AM PST On the surface, Earth looks like a very diverse planet compared to the monotone wastelands of the other planets. However, I wonder if this translates to actual elemental diversity, I.e. a relatively high standard deviation of atomic number. [link] [comments]  |
| Can you Find new prime numbers by multiplying all of the known prime numbers and adding 1? Posted: 19 Feb 2016 01:43 AM PST Our teacher showed us the proof to that there is an infinate number of prime numbers by using Euclid's theorem. If you add 1 to the product of all known prime numbers is it garanteed to get a new prime number? And if so why are people still looking for new prime numbers? [link] [comments]  |
| Posted: 18 Feb 2016 08:37 AM PST I was thinking about this on my way to work this morning. I know that if a planet is too far or too close to a star, then it's too cold or too hot to form life (according to modern theory at least). But if it's a matter of heat and sunlight, then would rotation matter? If a planet was tidally locked for example, so that one side was super hot and the other super cold, would it make it harder for life to form? Or if the planet orbited several times an hour and the light energy was dissipated, would that have an effect? [link] [comments]  |

| Posted: 18 Feb 2016 08:20 PM PST If matter and energy can be neither created nor destroyed, what happens when matter is converted into energy in digestion for instance, and then that energy is used? What happens to that energy/matter and is it still around in some form. Also, since I just read The Last Question by Asimov and the big question is whether entropy can be reversed here's another question. As I understand it, maximum entropy will be when the energy of the universe is evenly spread out across the universe and everything is in one homogeneous state. But if E=MC2 and matter and energy can neither be created nor destroyed but just change form would there be matter/energy at the end of the universe that would pool together due to gravity and glob up and de-homogenize the universe?

| Posted: 19 Feb 2016 06:14 AM PST If so, when you accelerate hydrogen nuclei in a particle accelerator, can you say that they become hotter the faster they move? [link] [comments]  |
| Why do small holes seem to bend light? Posted: 18 Feb 2016 05:44 PM PST If you bring a small hole to your eye, it seems to bend and distort light. What processes are at play to cause this? [link] [comments]  |

| Posted: 18 Feb 2016 07:23 AM PST So , every time I am having dinner with my parents , they tell me that I shouldn't drink cold water during a meal that consists of fatty meats . Their belief is that the cold water will make digestion more difficult and will cause long term damage to my digestive system . Seems bogus to me and I have not been able to find any supporting studies on the subject . Thoughts ? [link] [comments]  |

| Can the Van der Waals forces be applied to every molecule? Posted: 18 Feb 2016 08:52 AM PST For example, can every Hydrogen bond be explained with Van der Waals, or are they different? [link] [comments]  |

| Are there any actual health or mental benefits to having plants in your house? Posted: 18 Feb 2016 10:47 AM PST Not by use of plants as medicine or anything of that variety. Just by them purely being around you. [link] [comments]  |

| How exactly does the reverse Hermann Grid work? Posted: 18 Feb 2016 12:00 PM PST Here is the illusion What is happening at the intersections versus the non-intersections in regards to receptive field activity? [link] [comments]  |
| What effect does ambient temperature have on how well something burns? Posted: 19 Feb 2016 04:22 AM PST For example, does a bonfire burn better during the day than the night? Or does it have no effect whatsoever? [link] [comments]  |
| Posted: 18 Feb 2016 04:20 PM PST Or... would he have he's old memories...?(I think thats impossible) [link] [comments]  |
