| How did we eradicate Smallpox? Posted: 13 Dec 2018 02:26 AM PST How does an entire disease get wiped out? Do all the pathogens that cause the disease go extinct? Or does everyone in the human race become immune to that disease and it no longer has any effect on us? If it's the latter case, can diseases like smallpox and polio come back through mutation?

| Posted: 13 Dec 2018 06:09 AM PST I am aware of Dark Matter and Dark Energy. I know that space and time are intertwined. But does that lead to Dark Time or Dark Spacetime? [link] [comments]  |
| How does an electric arc choose it’s path in air (ex: a lightning bolt or Tesla coil)? Posted: 12 Dec 2018 10:04 PM PST They all seem so very random, but is there an actual scientific or mathematical equation for the path/arc they create? Or is it just randomly jumping from one molecule to the next? [link] [comments]  |

| How does my computer precisely know what time it is? Posted: 12 Dec 2018 04:47 PM PST It seems that even if a global server that is deemed the correct time sent this time to my computer, given latency and network delays, my computer would be working off the old time, without knowing how much to adjust for this delay. I realize you could easily calculate the round trip delay by feeding this same time back to the original computer, and say half it, but this doesn't seem very precise given the up and down legs could have different latencies. I realize the total variance wouldn't be huge, but still significant when accuracy matters for things like GPS, MLAT calculations, etc. Enlighten me, please. [link] [comments]  |

| Posted: 12 Dec 2018 07:53 PM PST I figure that if it's cold enough you would ordinarily experience hypothermia, it should offset the DNP's effect. [link] [comments]  |

| Posted: 12 Dec 2018 01:51 PM PST I understand what cancer is and how it works. What i'm wondering is how do cancers that are not in organs, like prostate cancer, kill you without spreading to any other body parts? [link] [comments]  |
| Can a conductor "saturate" in the presence of a strong electric field and become nonconductive? Posted: 12 Dec 2018 09:28 AM PST It's my understanding that there can be no net electric field inside a conductor. That if a conductor is placed in an electric field, electrons will migrate in the positive direction until the electric field generated by charge displacement cancels the externally applied field. Is it possible to apply an electric field so intense that all electrons have moved to their limits without canceling the external field? If so, does the conductor no longer conduct?

| Does alcohol type has any affect on cloud chamber work? Posted: 12 Dec 2018 02:55 PM PST Hello everybody. I'm trying to make myself working cloud chamber (simple scheme: https://imgur.com/a/5mLtIyI). There are 3 wooden walls, front wall is glass. Top is also wooden, with 2 large sponges attached. Bottom is from thick sheet metal which is sealed with silicone to wooden and glass walls. [link] [comments]  |

| Do different animals interpret smells differently? Posted: 12 Dec 2018 03:17 AM PST Say, a skunk's spray is stinky to us, but some other creature with a sense of smell may see it as attractive? [link] [comments]  |
