- How do super storms like Hurricane Dorian affect marine life as the storm travels through the area? Do they affect deep sea creatures?
- We know world's fastest creature both on land and sea, in terms of distance/second But what is the world's fastest being in terms of body lengths/second?
- Why are lunar landers wrapper in golden foil like material?
- What happened to the prehistoric forests and megafauna of Antarctica?
- Is it possible that millions of years ago there was an advanced civilization on Earth that due to geological reasons we don't have any evidence of?
- Are people with Congenital Insensitivity to Pain (CIP) unable to feel emotional pain in the same way they are unable to feel physical pain?
- So if you got shot and weren’t hit in any vital organs (heart, lungs, arteries etc), do you just need to stop the bleeding to survive?
- What's the difference between a subperiod and an epoch?
- MATBG: Phenomenological Extended-Hubbard-Model Cluster Calculation?
- What were some of the last Dromaeosaurids to exist before the mass extinction?
- Why does exit pupil diameter matter in telescopes?
- Yesterday I hiked a vertical mile and back over 15 miles of trail. I consumed only 3 average granola bars and 3 fruit leathers (like 1000 calories) in the 24 hours up to and during the hike. Where did my body extract that energy from?
- Why do hurricane predictions change so frequently/drastically over the course of the storm?

| Posted: 01 Sep 2019 10:56 PM PDT I was watching a Nat today while I was brushing my teeth and I thought holy shit, that tiny tiny tiny bug is hauling ass compared to its size. Like I'd imagine if a human we're able to cover it's equivalent body length/sec we would be super Sonic. Am I wrong? Is it truly not that fast? I would assume the smaller the animal the faster it could go in BL/S or "Body Lengths/ second. [link] [comments]  |
| Why are lunar landers wrapper in golden foil like material? Posted: 02 Sep 2019 07:07 AM PDT I have seen images of the Apollo 11 lander and it looks like it was wrapper in a golden foil. Saw the same with the released images of the recent Indian lunar lander. What is that golden foil and what purpose does it serve? Is it specific to the Moon or all extraterrestrial landers need it?

| What happened to the prehistoric forests and megafauna of Antarctica? Posted: 02 Sep 2019 06:10 AM PDT In the prehistoric past, ancient Antarctica was long part of the supercontinent of Gondwana, which also consisted of Australia and South America. During these times, the global climate was warmer, meaning that the Antarctic was covered in dense forests and inhabited by all sorts of megafauna, including dinosaurs. However, the modern Antarctica is obviously a very frigid and hostile place. The formerly great forests of Antarctica are long gone, and no land mammals inhabit the continent (although animals like seals and whale still inhabit the surrounding oceans, of course). Even penguins must depend on the sea for food. So what exactly happened to the formerly more vibrant life of Antarctica? How did the former forests and megafauna of Antarctica die out? How quickly did Antarctica transition from a temperate land to endless sheets of ice? Did it happen so suddenly as to spark a mass extinction event? Did Antarctica's climate change happen relatively recently? And could Antarctica ever be home to forests and large land animals ever again? [link] [comments]  |

| Posted: 02 Sep 2019 05:02 AM PDT People with congenital insensitivity to pain (or congenital analgesia) can't feel physical pain. According to a study by Eisenberger, the same part of the brain controls both physical and emotional pain. So, does this mean that people with this condition also cannot feel emotional pain?

| Posted: 01 Sep 2019 03:53 PM PDT For context, I'm watching a movie, no one has actually been shot. If you were, for example, shot in the arm, gut or shoulder by a small calibre weapon. Would the minimum required medical attention be a shit tonne of plasters (band aids for Americans) [link] [comments]  |
| What's the difference between a subperiod and an epoch? Posted: 01 Sep 2019 12:40 PM PDT The ICS recognizes the Mississippian and the Pennsylvanian as subperiods. The Mississippian lasted 35.7 million years and the Pennsylvanian 24.3. By comparison the Late Cretaceous lasted 34.5 million years. So what's the difference between an epoch and a subperiod? It clearly isn't length. [link] [comments]  |
| MATBG: Phenomenological Extended-Hubbard-Model Cluster Calculation? Posted: 01 Sep 2019 11:20 AM PDT https://arxiv.org/abs/1906.09274 I have been following articles that look at the properties exhibited by the 1.1 degree magic angle twisted bilayer graphene (MATBG). If I understand the abstract of this article correctly, they basically ran a tunneling microscope over an MATBG sample and got some unique data which couldn't be reconciled with our current understanding of electron interactions by a model known as the Hubbard model. Instead, their 'discovery' to me seems like an alteration of the Hubbard model, in effect creating a new theoretical framework to understand electron interactions of MATBG. Can someone explain the Hubbard model intuitively, and the changes to the model they made? I am trying to wrap my head around the significance of this. [link] [comments]  |

| Why does exit pupil diameter matter in telescopes? Posted: 01 Sep 2019 12:34 PM PDT As I understand it, your eye sees parallel light rays as coming from the same spot on whatever object you're viewing. So it seems like your retina shouldn't care whether the light entered it as a 5 mm tube of light or a 4x concentrated 2.5 mm tube of light. Right? So why would a telescope with a larger exit pupil appear brighter? [link] [comments]  |
| Posted: 01 Sep 2019 11:16 AM PDT I know the liver will store and create glucose, but surely not enough to supply >5000 calories of exertion, right? And under conditions of starvation your body consumes muscle before fat, but is that the same in circumstances of acute demand (during which those muscles are being heavily used)?

| Why do hurricane predictions change so frequently/drastically over the course of the storm? Posted: 01 Sep 2019 09:30 AM PDT I was watching the news today and they said Hurricane Dorian had increased to a category 5 storm, when just yesterday it had been decreased to a category 3. I know weather/meteorology isn't an exact science, but why does it seem like the hurricane predictions are just wild guesses? [link] [comments]  |
