| Why is it impossible for objects weighing less than 0.02 milligrams to form a black hole? Posted: 28 Jan 2017 02:01 PM PST Whats so special about that mass that you cant form a black hole below it? [link] [comments]  |
| Do octopuses have a dominant right or left side? Posted: 28 Jan 2017 08:43 AM PST I'm drawing an octopus right now, and I'd really like to know. [link] [comments]  |
| Posted: 28 Jan 2017 08:12 AM PST In Computing Machinery and Intelligence he talks about overwhelming statistical evidence of Telepathy. Does anyone know what he was most likely referring to?

| What kept a massive black hole from forming immediately after the Big Bang? Posted: 28 Jan 2017 01:39 PM PST If all the mass in the universe was in the same place immediately following the Big Bang, how was an insanely massive black hole not formed? What kept it from collapsing in on itself instead of spreading out? Is it because of it's mass? Light can't escape a black hole, but can something with enough mass traveling near or at the speed of light escape? [link] [comments]  |

| Are there any factors that have actually been shown to affect which sex a baby will be when born? Posted: 28 Jan 2017 10:38 AM PST I've heard of anecdotal reasons like mother's diet but have there been any serious studies on this topic? [link] [comments]  |
| Posted: 28 Jan 2017 12:44 PM PST We hear about a new "largest prime number ever" being discovered now and then. But we clearly dont know of every prime number below it (distributed computing projects like PrimeGrid discover new primes all the time which are smaller than the largest known). So I have a few question, just to satisfy my own curiosity really:
Thats it I think. Feel free to fill in more though. [link] [comments]  |
| Why is beet juice a good addition to de-icers from a chemical stand point? Posted: 28 Jan 2017 09:27 AM PST I want to ask why the addition of beet juice to de-icers is beneficial from a chemical point of view, for example adding it the calcium chloride and salt brine then spreading it on roads to keep them clear of ice.

| What mass does a planet have to have to be able to keep light in orbit? Posted: 28 Jan 2017 07:42 PM PST I know gravity will bend light, and I know gravity is a function of a bodies mass, but at what mass can a body bend light around its self enough to essentially keep it in orbit? Is that what is meant by a black hole has gravity so strong light cannot escape? [link] [comments]  |
| Why is osmotic pressure able to raise a water level against gravity? Posted: 28 Jan 2017 09:47 AM PST My understanding of diffusion is that all the particles in a fluid randomly move around within the fluid volume. Eventually they are evenly spread out, reaching equilibrium. Models of such systems are defined by concentration gradients of the particles of interest. I thought that the idea of the concentration gradients being the "driving force" of diffusion was just a convenient way to intuitively grasp the process of diffusion, and that such a force doesn't really exist, because the particles are randomly moving and their diffusion is statistical. However, in the case of a semi-permeable membrane separating a high-salt concentration aqueous solution from a low concentration one, the diffusion of water across the membrane actually forces the solution levels on either side to be uneven, like in this illustration. I would have assumed that, if the diffusion of water across the membrane were just statistical chance, that the hydrostatic pressure would be able to keep the levels equal by pushing the water molecules back across the membrane once they started to raise the liquid level. Instead, the "osmotic pressure" must actually exist as a real pressure and balance the hydrostatic pressure of the raised water level. What molecular interactions between the water and the solutes, or whatever else, causes the system to come to this equilibrium state? [link] [comments]  |
| Why isn't mastocyte degranulation as a response to IgE Fc receptor engagement considered ADCC? Posted: 28 Jan 2017 01:16 PM PST Eosinophil-mediated ADCC involves eosinophils recognising IgE antibodies bound to an antigen via FcεRI receptors, which causes them to degranulate, releasing MBP and various cytotoxic enzymes. Mastocytes also possess FcεRI receptors which, when stimulated by an antigen-IgE complex, cause the mastocyte to degranulate. The mechanism seems similar enough. The contents of the granules are mainly focused on producing an inflammatory response, but cytotoxic substances are also released (according to my immunology textbook), so why isn't this considered ADCC?

| Is the reaction of Silicon and Chlorine dangerous? Posted: 28 Jan 2017 06:15 AM PST Hello. So I'm doing my first ever Chemistry project for school. The project is: Sorry for this weird question. If this is not fitting for this subreddit (because it's all kindoff proffesional here) please tell me or remove this. [link] [comments]  |
| Posted: 28 Jan 2017 07:49 AM PST I was recently conducting a BLAST search of an unknown gene sequence and there were fewer related nucleotide sequences as compared to when I searched the protein sequences. Of course this could be based on fewer submissions to the nucleotide sequence database than the protein database but I think it may be explained by the degeneracy of the genetic code but I'm not sure.

| Posted: 28 Jan 2017 08:11 AM PST I am a structural FEA analyst, primarily concerned with material nonlinearities, but also contact problems. We use codes that use NL Krylov methods and Newton methods. It would seem to me that quantum computers/processors could efficiently solve these systems, but retrieving the results may be problematic. I have a slew of questions, please don't feel obligated to solve them all: 1a. Can QC solve these systems? 1b. Efficiently? (Qubit per DOF? Time to solve? What's the proper measure?) 1c. Is it possible to retrieve accurate results efficiently? (For example, I postulate a QC might solve the same problem 1000s of times to retrieve the solution (decoherence?). If each solve is very, very fast, it might still be more efficient than standard CPU/GPU) 2a-c. Same questions, but with D-Wave 3a. Does the amount of qubits limit the size of problem that can be solved, or is it similar to "given enough time and memory a single CPU core can solve any-size problem" ? If yes, what's the DOF/qubit scaling law? (Sorry about formatting, on mobile) [link] [comments]  |
| Does frequency of sound affect how much it's "carried" by the wind? Posted: 28 Jan 2017 06:15 AM PST I guess I should state my assumption first. If you are standing upwind of a sound in a strong wind, you can't hear it as well as if you were standing the same distance downwind. I feel like this happens, but I have no concrete proof. So a first question is: is this really the case. If so, do higher frequency sounds get "pushed" by the wind more easily than low frequency ones? The other day I was upwind of my car and hit the door lock, and the little beep it makes was not audible to me at all, even though I was only about 5 meters away. If the sound it made had been lower, but at the same volume, would I have heard it? [link] [comments]  |
