- If lower gravity means lower atmospheric pressure, is flight easier on a smaller Earth-like planet or a larger one?
- Why is it that the risk of contracting Covid-19 from infected food is lower than touching your mouth with infected hands?
- When you taste something sweet after eating another sweet thing, the second thing doesn’t taste as sweet. Is that due to the taste receptors themselves not firing as often or is it your brain filtering out the signal?

| Posted: 04 Apr 2021 05:35 AM PDT Hi there, A quick web search along the lines of "can you get covid from eating food" will present you with dozens of articles with input from epidemiologists suggesting that eating food that is contaminated with Covid-19 is unlikely to get you sick. However, just about every article on the subject of Covid-19 will remind you not to touch your mouth before thoroughly washing your hands. Why are these two scenarios so different? Both result in the virus in your mouth / on your lips, so why is eating contaminated food so much less likely to infect people? [link] [comments]  |

| What causes dark circles under eyes? Posted: 04 Apr 2021 04:08 AM PDT I've always been really curious what the actual physiology of dark circles is but every way I've ever tried to look it up just tells me that dark circles are caused by lack of sleep. [link] [comments]  |
| Is there a corrosion function? Posted: 04 Apr 2021 06:45 AM PDT I was wondering if there was a function such that corrosion % could be calculated by surface of material corroded (ex iron)/ total surface? I'm looking for a simple function that assumes a lot of things like the Ideal Gas Law PV=nRT. I would only be accounting for time elapsed, and ambient temperature, ambient pressure and relative humidity. Thank you and I hope this function exists lol [link] [comments]  |
| What exactly does acetaminophen do your liver? Posted: 03 Apr 2021 10:00 PM PDT I notice my bottle of Tylenol (aka acetaminophen) says to not take more than a recommended dose or it'll hurt your liver. So what happens to your liver if you take too much? [link] [comments]  |
| Why does tantalum behave differently under AC current than DC current? Posted: 04 Apr 2021 08:24 AM PDT In this article about the history of the lightbulb Ainissa Ramirez says that " When supplied with direct current, tantalum light bulbs burned for more than 900 hours—more than a month. But their lifespan plummeted by 70 percent with alternating current, which was predominant on American electrical grids. Sections of the tantalum threads became brittle from the electricity and broke when pulsed by the alternating jolts. Coolidge made little progress with tantalum and worked briefly with molybdenum before he eventually focused on tungsten." This is backed up by other sources such as here which also does not mention the cause of the issue. What is the mechanism here and why does it only apply to tantalum and not the very chemically similar tungsten or other metals? [link] [comments]  |
| What happens when you point a flashlight at a flame? Posted: 04 Apr 2021 07:35 AM PDT Does the flame reflect light back at you? Does it cast a shadow? Is it different from shining a light on lava? [link] [comments]  |
| How does one shot (not both) of Moderna/Pfizer compare to J&J? Posted: 03 Apr 2021 04:38 PM PDT I'm trying to understand the literature on differences in effectiveness, in getting it and in serious symptoms/hospitalizations and deaths, between J&J and just one shot of Moderna/Pfizer. My current understanding is that J&J was tested when other variations were circulating, and on more people, so its efficacy number on its face is misleading. And, its about as effective at preventing hospitalizations/deaths as both shots of Moderna/Pfizer--what about one shot? Anything else to consider in comparing one shot of Moderna/Pfizer to Johnson and Johnson? Thank you for helping me understand the science. [link] [comments]  |
