| Is there an actual reason the Sun and the Moon are the same size in the sky? Posted: 27 Apr 2016 06:57 PM PDT In school, I was taught that it was just a coincidence that the Sun and Moon are the same size in the sky but it seems like such a rare coincidence, there'd have to be a reason, wouldn't there?

| Posted: 27 Apr 2016 10:33 AM PDT Inspired by a similar thread in /r/math. Feel free to ask follow-ups. Edit: for those posting, consider becoming a panelist and getting flair by posting to the stickied panelist application thread! [link] [comments]  |

| Is the universe expanding in three dimensions or four? Posted: 27 Apr 2016 02:07 PM PDT If space has been expanding since the Big Bang, is it expanding in the three spatial dimensions, or is spacetime also expanding in the time dimension? If it's also expanding in time, how does that actually affect progression of time? Does it slow? [link] [comments]  |

| Posted: 27 Apr 2016 08:11 PM PDT Getting an operation in a few weeks. I've been told to take some vitamins a few weeks before. I understand we get vitamins through food but, how are they made in pill form? They sure are expensive, maybe make my own if it isn't to hard. [link] [comments]  |

| Posted: 27 Apr 2016 02:35 PM PDT IIRC, for measurements like the kilogram we base it off the number of atoms of a specific element. How exactly do we come up with a uniform version of a second, since time is kind of more abstract than mass. [link] [comments]  |

| Posted: 27 Apr 2016 07:10 PM PDT Increasing the reaction temperature increases the number of collisions and number of molecules traveling at or above the activation energy, which would favour product formation. However, the overall neutralisation reaction is exothermic, so by Le Chatelier's Principle adding heat should have the effect of favouring the reactants. This is so fundamental, pls help.

| Posted: 27 Apr 2016 08:10 AM PDT One website (and it is by no means alone in making this claim) suggests: > Do "leg drains" by lying on your back with your legs extended vertically and feet propped against a wall for three to four minutes. This drains the blood out of your legs so fresh, clean blood can be pumped back into them when you stand up. Something about the idea of "fresh, clean blood" rings false. But is it?

| Do illnesses like influenza leave small long-term after effects on normally healthy individuals? Posted: 27 Apr 2016 06:18 PM PDT Influenza strains can be quite serious diseases that can kill but for most healthy individuals it can be survived with a high likelihood. However, many disease have after effects caused by symptoms experienced through the course of the disease. Have there been studies done to examine if relatively minor diseases have caused lasting effects such as increased susceptibility to future illness? Is there damage accumulated in areas the body isn't typically replacing cells? [link] [comments]  |
| Posted: 27 Apr 2016 10:44 AM PDT link to the apocryphal tale here: https://dontdontoperate.wordpress.com/2012/08/09/wade-davis-zombies-the-inuit-and-the-shit-knife-louis-riel-and-canadian-history/ Previous discussion of this story on TIL: I underline that the tale is from Inuit oral history, so it may have grown in the telling. Could such a knife hold an edge sufficient to kill, skin and butcher a dog? Could it be mechanically resilient enough to do the job the tale claims it did? Are the faeces necessary? Would not simply making a similar tool out of ice/snow and spit be just as effective (if true)? [link] [comments]  |
