| How to flies survive winter in the northern hemisphere? Posted: 21 Mar 2021 03:52 PM PDT We had the first nice day out that was above 50F in Canada and there were already flies buzzing about. I didn't think they could survive the deep freeze of the winter and didn't think there was time for them to grow from eggs or maggots this early in the season. Did they just hide out all winter or do they freeze and thaw like amphibians and reptiles do in the colder climates? [link] [comments]  |
| Posted: 22 Mar 2021 04:00 AM PDT Hello r/askscience! We are infectious disease experts from the University of Chicago Medicine. Emily Landon, MD, specializes in infectious diseases and leads the academic health system's infection control and prevention efforts. As the medical specialist for the High-Consequence Pathogen Preparedness Program, Dr. Landon has helped steer UChicago Medicine, the University of Chicago, and its affiliates through the COVID-19 pandemic. She also regularly advises businesses, industries and government officials on how to best respond to the global crisis. Allison Bartlett, MD, MS, is a pediatrician who specializes in the medical management of acute and chronic infectious diseases in children, and has spoken on the unique challenges and medical issues facing kids during the COVID-19 crisis. As multiple COVID-19 vaccines are rolling out around the world, infectious disease experts and government health agencies are beginning to issue new guidance on all aspects of life, from social distancing to mask wearing. But in this nebulous state where some are vaccinated and some are not, what does that mean for day-to-day life? What can (or should) you be doing differently, or the same, once you've been vaccinated? What can you expect after getting the vaccine? We'll be on at 4:30 PM ET (20:30 UT), ask us anything! Links:

| How much sound energy does a rocket create? Posted: 22 Mar 2021 08:07 AM PDT I've read that the Saturn V was recorded to produce 204 dB of sound. With an online conversion tool, I found this is about 2.5e+17 watts. Thus, each second, 2.5e+17 Joules of sound energy is generated by the engines. For reference, the largest nuclear bomb released about 2.1e+17 Joules, according to Wikipedia. The first stage of the Saturn V was active for around 160s. But I find it hard te believe that that first stage released nearly 200 times more energy than the largest nuclear bomb. And the rocket engines don't only produce sounds, so their actual energy output is even more. Clearly I must have missed something in my calculations, but I can't find where I went wrong.

| How can a double bonded oxygen to a carbon form additional polar contact to water molecules? Posted: 22 Mar 2021 05:26 AM PDT I'm looking at the polar contact shared between a phenol oxygen of an aromatic ring and a double bonded oxygen to carbon of a carbonyl carbon. Both of these oxygen's are forming polar contacts to water within the protein of interest and I'm confused as how a double bonded oxygen which can only have two bonds form this polar contact of water with it's oxygen?

| Posted: 21 Mar 2021 09:42 PM PDT " 3D conversion process essentially involves rotoscoping thousands of images in every frame. " " "Arnold really needed to look like Arnold in 3D because he's such an iconic figure," says McCoy. "He's got such an iconic face and build, that if it looks wrong, it's always going to look wrong." In fact, this aspect was so important that Stereo D even upped its number of rotoshapes on the conversion than usual. "I would say for a normal movie be, we might do 100 per cent roto-shapes, but we did like 150 or 200 per cent roto-shapes for James Cameron." " I thought rotoscoping was like adding lightsabers/lasers on front for example? What exactly could they add in front to produce 2 pictures? You don't have two pictures of Arnold at two different angles per shot so now what? There is no way they are creating 3d models of every image and simulating two different eyes looking at it, what kind of trick are they using? [link] [comments]  |

| Is the common cold more contagious or more common than illnesses like the flu and strep throat? Posted: 21 Mar 2021 03:18 PM PDT I get a cold maybe once or twice a year, but I never get more serious illnesses like the flu, strep, etc. [link] [comments]  |

| What makes shaving cream the ideal substance to shave with? Posted: 21 Mar 2021 07:48 PM PDT Why shaving cream? Why not soap or shampoo or coconut oil? What properties in shaving cream make it so useful? I'm imagining it reduces friction and hydrates your skin, but how is that different from most soaps or detergents? [link] [comments]  |

| How do they determine property ownership on moving fault lines? Posted: 21 Mar 2021 06:31 PM PDT I was watching a History Channel show about the San Andrea's fault. In the early 1900's, there was a massive earthquake that moved one tectonic plate 8 feet from the other. There is a famous picture of a fence that was whole before the quake, but half of the straight fence broke away and was a separate straight line 8 feet south of the original fence. Basically, the original fence was built over what we now now is a fault line and was split in half and one half slid down from the original by 8 feet. My question is, who would own that 8 feet of property where the fence moved? Would the land ownership remain with the actual land itself, or would the original boundaries or GPS points be the land ownership boundaries? What if there was a pumpkin farmer on one side of the fence, but a corn farmer on the other. Who will then own that 8 feet of pumpkin patch that moved into the direction of the corn land? Thanks for any info you can share. The San Andrea's Fault [link] [comments]  |
| If you're exposed to a disease, what factors determine if you'll get sick? Posted: 21 Mar 2021 08:16 AM PDT We always talk about immune system health - what does that mean? Will anyone get sick if exposed to a contagious disease for long enough? [link] [comments]  |
| Sound and electromagnetic waves in space Posted: 20 Mar 2021 10:58 PM PDT So we know the speed of light, it's 3 x 10 to the eighth power, but that got me wondering. Sounds are waves as well, so is all visible light. So why doesn't sound travel in space but light can, what is stopping sound waves from traveling but radio waves and light waves. Lastly I know that this question sounds like a homework question but this is just something that has bothered me sense 9th grade astronomy and 10th grade physics [link] [comments]  |
