Cryonics: Scam or potentially feasible?

2 more posts in this thread. [Missing image file: ]
So there are a couple companies which freeze bodies with the hope of bringing them back in the very distant future. But has there actually been any research done into cryonics or any attempts and revitalizing dead cells? I feel like this is a bullshit fantasy for profit and has 0 scientific basis.

Winter is arriving in my shitty part of the world, this happens since the earth simply tilts on it axis like a tiny bit, how far away or closers to the sun could we get before we were either froze or evaporated?

Despite every popsci""""entist"""" going on about it, I've heard that science has abandoned it as a principle. Is this true?

Data Crunching Server Build

7 more posts in this thread. [Missing image file: ]
So I'm building a server at work for data crunching massive amounts of data (up to 1.5 TB at a time). Our normal data crunching computers - which run Windows 10 with 512 GB RAM, two Titan X's, 2 CPU's (Intel, forget what kind, but they're good) aren't cutting it in terms of doing the work in a timely matter. One adjustment in the tweaking of a data set takes our computers about 5 minutes until we see the effects of the tweak. So what I'm asking you all, is what equipment would be included in a data-processing server that could crunch these types of data sets? My budget is under $200K Pic related

This man's chromosomes were destroyed by radiation. That means his body did not have a blue print anymore, he was only a piece of meat at micro second the radiation hit him. Given the two weeks before his skin started to fall off, how is a human being still able to communicate, eat, breath, and sleep when the body doesn't even know what to do??? If his body didn't know what was what, does that mean that he didn't feel pain because the pain signals didn't know what to do??

Average age the water molecules we live with: billions of year or seconds? In school they said most water is "as old as the earth", in chemistry they said "water as a solution constantly splits in and recombines from H+ and OH- ions within seconds". So, if I fill a glass of sea water, which average age can I expect the water molecules to have?

Let's build a better electoral system with math

47 more posts in this thread. [Missing image file: ]
Okay... no shitposting about the election. This isn't about being butt-blasted about >muh popular vote or anything else like that. I want to start a serious think-tank about using math to design a better electoral system in the United States. I've been curious over the last several days if there is possibly a more efficient and "fair" voting system in America. A lot of people are seriously considering abolishing the electoral college in favor of a purely popular vote. I believe /sci/ can think up some more logical, fair systems based on simple mathematical principles. Is there a better system out there? There are a lot of smart people on this board, so let's get a brainstorm going. The main concerns so far, at least the ones I can see, are: -How to make sure every vote gets counted. For example, republican votes in California mean literally nothing. -How to make sure every state and county within is weighted fairly, regardless of size. Note: feasibility can be thrown out the window here. Obviously some systems that might work could never be implemented due to complexity/resistance from political parties. Let's focus purely on the most fair system possible and the maths behind it.

SQT - Stupid questions thread

21 more posts in this thread. [Missing image file: ]
I don't understand the concept of potential energy. "When a test charge q_0 is placed in an electric field created by some source charge distribution, the electric force acting on the test charge is q_0E. The force q_0E is conservative because the force between charges described by Coulomb's law is conservative." Okay this is all fine. "When the test charge is moved in the field by some external agent, the work done by the field on the charge is equal to the negative of the work done by the external agent causing the displacement" What does that mean? If there is a charge q_0 in an electric field E and I move that charge along the direction of the electric field then the work I do on the charge is qEd correct? Then then the work done by the field on is -qEd? Can someone give me a better explanation? Where does the negative sign come from? Some clarification on work done by the external agent and work done by the field would be helpful too. Why does the field do work when I am the one that moves it?
