| How many mouse clicks would it take to put the space shuttle into orbit? Posted: 23 May 2020 04:50 AM PDT It takes energy to click a mouse button. How many clicks per second would it take to launch the space shuttle entirely into its usual orbit height? [link] [comments]  |
| Do neurons or other cells generate biologically functional magnetic fields? Posted: 22 May 2020 06:20 PM PDT Just learning about electromagnetism, and I'm curious whether anything is known about magnetic fields generated during action potentials. Do charged molecules interact/move with magnetic fields for functional purposes in our body? Further, do any human cells use magnetic interactions to communicate? Do any other animals use magnetism to communicate? Is there a magnetic-gated channel perhaps, similar to a voltage-gated channel? Thanks! [link] [comments]  |

| What is the electrical current actually doing in am antenna? Posted: 22 May 2020 09:14 AM PDT From what I've read so far, an antenna is just a conductive piece of metal and radio waves induce an electric current in it which can be decoded into sound or images. But a piece of metal can't discriminate and is being bombarded by every radio and TV station and wifi signal and garage remote in the area right? So are the electrons just flying around chaotically? How can you make an actual electric current when the electrons are being pulled in every direction at once? [link] [comments]  |

| Why is the earths magnetic field the way it is? Posted: 22 May 2020 01:23 PM PDT While watching a documentation on planets I was wondering why the magnetic fields always seemed to "emit their magnetism" (please excuse my lack of technical terms) on the north or South Pole. Visualizations of the magnetic fields always show the currents making their way from the poles. Since planets are (almost) a sphere I wondered why poles couldn't just be somewhere else. I figured it has something to do with the tilt and rotation, or the not perfect sphere. However, I am not invested enough to figure it out myself so here I am. I hope my amateurish explanation and question is understandable! Thanks for your answers in advance. [link] [comments]  |
| How does loss of oxygen in oceans lead to ocean acidification? Posted: 22 May 2020 10:48 PM PDT The role of CO2 in ocean acidification is well established. It intuitively makes sense too. The more CO2 is absorbed, the more carbonic acid will form in the oceans. But how does loss of oxygen also lead to acidification? Source claiming that to be the case. [link] [comments]  |
| What exactly would earthquakes of magnitudes 10, 10.5 or 11 do to the planet? Posted: 22 May 2020 03:44 PM PDT Are earthquakes of these magnitudes possible? If not, why and are we able to tell what magnitude the strongest possible quake on earth could have? [link] [comments]  |
| How is negative Kelvin achieved? Posted: 22 May 2020 11:05 AM PDT I recently learned about negative kelvin, but cannot understand why it is considered a negative temperature. Here is where my understanding is at: 1. I understand that atoms are brought to near 0K, meaning they have near zero kinetic energy. 2. I understand that these atoms need to have an upper energy limit so that they can be in a state of maximum potential energy during this process. 3. Temperature is not just the kinetic energy of particles, but includes interaction and potential energy as well. Where my understanding breaks down is how inverting the kinetic and potential energies creates a negative Kelvin temperature. Why does taking an atom to it's upper energy limit create a negative temperature? I read this article on it: https://www.sciencedaily.com/releases/2013/01/130104143516.htm but I still do not understand it, and the hill/ball analogy did not help. Edit: After further reading on the subject through this subreddit I have a basic understanding of Thermodynamic Beta and why negative Kelvin is considered negative, but I am still confused about the need for the energy limit, and inversion of potential and kinetic energies.

| The body creates the highly toxic chemicals used in decomposition, where do they come from? Posted: 22 May 2020 05:55 PM PDT What are they made of? How long does it take for a body to decompose to something unrecognisable? [link] [comments]  |
| Can you still differentiate aromatic rings and normal pi bonding in zero-field nmr? Posted: 22 May 2020 05:36 PM PDT If the anisotropic effects of these bonds/rings is what causes the greater than usual chemical shifts would you still be able to see these shifts in a zero field experiment?

| Why has Coronavirus spread around the world from region to region in hotspots? Posted: 22 May 2020 08:48 PM PDT Infections were obviously greater in China and Asia generally initially, then Europe And the Middle East, then North America. Now it appear that South America and Africa is where the virus is spreading most? Is it simply a question of where most travelers to those regions come from (i.e Africa and South America are a few steps removed from direct travel from Asia) or is something more going on?

| How old is the inner core of the Earth? Posted: 22 May 2020 06:41 AM PDT I am trying to find out when the inner core was formed but every source I look at ranges too much from 50 million years after the earth formed to even 500 million years ago which over a 4.5 billion span is a lot. I understand it formed from the heavy iron and nickel materials sinking to the centre and solidifying from the pressure, but I am trying to understand the history of the earth and would like it if someone could clear up the age of the inner core for me. :) [link] [comments]  |
