| Is there a way or has there ever been a case where protons are removed from the nucleus of an atom? Posted: 29 Sep 2017 06:28 PM PDT I don't know much about atoms and science-y things, but I've been wondering if there ever has been an instance where protons were removed from the nucleus of an atom, or if there's a theoretical way to do so. If there has been, what affect did it have on the atom. If it's purely theoretical, then how could it be accomplished If it can't be done, then why? [link] [comments]  |
| Posted: 30 Sep 2017 02:09 AM PDT With all the tensions between US-NK and the later's reentry test failures, I'm curious if even a failed nuclear warhead can have grave consequences on its target. Plutonium is one of the most toxic elements to life that we know of if ingested somehow into our bodies. Lets presume that the reentry vehicle of the North Koreans is similar to the american W87. The materials used in the design of the cone are state secret (Most likely something with good refractory properties, like carbon etc), but lets assume that the entire vehicle fails/cracks open exposing the peanut core at high altitude and allows it to burn into the atmosphere. Are there any safety mechanisms for this situation, at least used by the nations that have experience with nuclear weapons? What is the trigger of such a weapon, and could such a fail activate it and detonate it into the high atmosphere? [link] [comments]  |

| Constant acceleration/deceleration as artificial gravity? Posted: 30 Sep 2017 05:27 AM PDT One of the main challenges of a crewed mission to Mars is the prolonged period of microgravity and its negative health effects. Setting aside the limitations of fuel, would it be possible to launch a ship that had a constant one-g acceleration until halfway to Mars, and then a constant one-g deceleration for the rest of the trip? I know orbital mechanics are tricky, so I'm not sure that it would work, but if we somehow had an engine and fuel source that could do it, the crew would effectively have artificial gravity for almost the entire trip.

| Where do the atoms come from when life is created? Posted: 29 Sep 2017 01:21 PM PDT Are the pulled from the atmosphere? Generated somehow? Ex: when offspring is created, I get the cellular reproduction part, but not where these atoms come from to create the new cells. [link] [comments]  |
| How long did it take for islands to breakaway from their continents? Posted: 29 Sep 2017 11:54 PM PDT So Madagascar broke away from Africa over 120 million years ago: But exactly how long did it take for the island to completely break off? What would the transition look like? [link] [comments]  |
| How does algae reproduce in mountain streams without being "flushed out"? Posted: 29 Sep 2017 01:25 PM PDT I've been taught that algae reproduces either asexually or through spores. How then do algal populations persist in mountain streams? Without a means of upstream dispersal, it seems that any population would be flushed downstream within a number of generations.

| Would sound waves propagate through any arbitrary amount of gas in the vacuum of space? Posted: 29 Sep 2017 06:15 PM PDT If you and I were floating in space, totally exposed, and I screamed directly into your ear with lungs full of air, would you hear anything? In other words, is the air in my lungs voluminous enough to allow sound to travel through over short distances in a vacuum? [link] [comments]  |

| What is the difference between machine learning and data analytics? Posted: 29 Sep 2017 10:46 AM PDT I understand that machine learning is a way to teach AIs by using large data sets while big data analytics is essentially finding solutions using big data sets, but they seem to have the same outcome. I can see how I'm comparing apples and oranges here, but I can't seem to get my head around it. Please help. [link] [comments]  |
