Okay don't crucify me for this.
In the latest ancient aliens episode, they mentioned that some scientific reports shows that if you subject mercury to a very high level of eletrostatic charge and then spin it, you get a gravitational thrust which allows you to create inertial force that can counteract the gravity.
Is there any truth behind this ?

There are two identical objects, i apply 5 newtons of force on the first and it moves, i do the same to the second object but it doesn't move, the chance of this happening is non-zero, in this hypothetical situation if the cause of the first objects movement is applying the force then what is the effect of the force application on the second object if the two objects are stationary?
Wrote this because saying the force application causes the object to do nothing doesn't make scene to me because it was already doing nothing,
it's like saying the object does nothingx2. These two objects have the same mass.
Or is it the case that 100% of the time two identical objects will react the same if tempered with in the same manner?
help a brainlet out.
Hello /Sci/ I have a simple challenge for you.
If I have a 10ml vial and 2.5 mg of a substance with a molar mass of 209.29 how much water must I add into the vial to fill the vial to 10ml, no more no less.
Let's see if any of you actually paid attention in your Chem classes.
The answer is your question is fucking stupid.
t. Chemist
Seeing as you didn't answer it and just bashed the question than it's more than likely you can't solve the solution

I'm incredibly interested in picking up ME as a hobby, and I'm not too sure where to start. I want to stay a physicist though.
A programmable lego or kinect set? Idk. Most mechanicals I saw were working on simulations in matlab and shit. They really didn't do anything intricate, just reviewing real physical properties (stresses and such) and production methods. I almost forgot production, they did a lot of that side. Different types of physical and chemical bonding, lots of shit. Look up your universities curriculum.

>Idk.
Then why are you replying you fucking mouthbreather?

Literally every web browser has an embedded search engine at the top. You're the nigger too stupid to use it.
I assumed you weren't a dribbling retard and wanted our personal experience. I was mistaken.
How do you deal with the fact that you went to a non Oxbridge / MIT / Stanford / Caltech / Ivy League university and were surrounded by anti-intellectuals and had a much less rigorous curriculum for the entirety of undergrad?
It feels fucking awful to me. When I see giant university buildings I am in disbelief. These are monuments to a broken society that celebrates mediocrity.
And yet here you are right now.

By not caring. There are opportunities everywhere for those smart enough to look for them and at this point I can tell you that I have gotten more professional opportunities as a student than most of the people at Harvard ever will.
I mean, how common is it, even for Harvard people, to get internships related to their education from their freshman year? I will...

They had some problems inflating the expandable module yesterday. Probably because of higher friction of the materials than initially expected.
Trying again today.
they're releasing short bursts of air into the module and wait for it to settle and then release another short burst.

After yesterdays failure they depressurized it again, however it still expanded a little overnight. (see pic)

What should i practice when i'm going to studies r1 and r2 math next semester? I'm already bad at math but i really want to do my best and succeed somehow, but it have been years since i was on the school bench and i was barely even passing back then, but i also didn't care at all.
Please help me anons.

>r1 and r2 math
Are you Norwegian?
>>8105977
Yes i am. Isn't r1 and r2 something done by americans too?
What are the best programming languages for modelling with PDEs?
I'm looking for something FAST, doesn't matter if the syntax is a total pain in the ass to learn.
>>8105919
MATLAB is good.
>>8105936
Isn't there something faster?
>>8105941
Faster to learn, faster to code or faster to execute?
If you have some programming experience, MATLAB should only take a few weeks of solid work to get the hang of.

Is convex optimization useful for a CS pleb like me?
convex optimization is useful to every single person on earth.

What percentage of observations that we make can be predicted?
Let's say you had unlimited computational power, and all of the world's most predictive scientific models were translated into algorithms. How much of what is happening in the real world would you then be able to predict?

Is everything algorithmable?
Some say JSON is like JavaScript.
What can this even mean?
How can a data format be like a programming language??
Also, how does JSON differ from an (algebraic) data type? Like trees.

THE FIRE RISES
According to /sci/, wat do with nuclear waste? Are any long term non sci-fi solutions feasible?
>>8105599
Yes. The really short version is we dig a very deep hole, a "bore hole", and dump the waste down there. Problem solved.
For a longer version, see this link:
http://thorconpower.com/docs/ct_yankee.pdf
We already know the solution: Bury it.
https://en.wikipedia.org/wiki/Natural_nuclear_fission_reactor
Oklo was effectively a natural Uranium reactor (using rainwater as moderator) that "operated" for hundreds of thousands years nearly 2 billion years ago. Yet despite this, most of the stable fission products and actinides from these "reactors" moved only CENTIMETERS in their veins.
This is not a scientific issue anymore. It is only a political one.

Recycle that shit and execute the fucking businessmen who don't want to because it's slightly cheaper not to.
