Do other universities even compete?

If MIT was the only university in the entire world we'd still do just fine.

You amerifags are really blind by your stupid national proudness, thinking MIT NASA and stuff are the greatest in the world. KEK, ridiculous. You think american scientists made up the bomb with Einstein, whom you adulate as fuck, when he just wrote a letter to support the project, lead by Von Neumann (Hungary). Absolutely nothing crazy comes out from MIT in my field (alg. geom/alg. top in pure math).

In terms of undergraduate student ability there are other universities outside America that probably have equal talent (in China, India, Japan for example, because of their incredibly hard entrance exams).

But if you're talking about research, MIT is undoubtedly deserving of its reputation of being one of the best universities in the world.

/sci/, brainlet here.

I just don't understand why nothing can go faster than the speed of light.

For example: If you were on a rocket in space which was accelerating continuously of 1g, and the faster you go the more energy is required to keep the acceleration at that rate, right?

But what if you accelerated at 1g for a bit, turned off the engines of whichever types you have, then switched them back on to accelerate again. Would you 'reset' the output required to start the acceleration all over again and simply adding on to the previous speed you had?

Also in the above retarded question, if it doesn't work then fucking why not?

If an element of a simulation metabolizes with its simulated environment and reproduces with imperfect hereditary material, is it alive?
12 posts and 1 images submitted.
>>
>>8305506
no, because life does not include simulators or interpreters. maybe you found a remarkable local minima for an optimization problem (your fitness function). In order to make it actually be alive, you need a physical environment and some chemical interpreter running your code for a metabolism, making it reproducing itself. (And even then, you might create some edge-case of life, like viruses, which do not have a metabolism themselves, but only reproduce due to being interpreted in a host lifeform's metabolism.)
>>
Oh shit nigga, is that some motherfucking Tierra?
>>
>>8306862
But what if you consider the meme hypothesis that our universe may be a simulation? Is the simulation not its own universe, thus the lifeforms in it really alive to that universe?

hey /sci I have a question.
If the radiation is stronger at it's source and gets weaker within a few feet, how does wifi still end up delivering all the information it needs to?
I mean, if I have a router and I sleep beside it for 9000 hours straight I will probably feel a mild burn.
But if i move a few feet away I won't, yet I still recieve all the information I need from my wifi.
How do you explain this?

1. Radio waves are not going to burn you.
2. The signal doesn't become invisible a few feet away. Your devices can still detect the signal as far away as the other side of your property.

If heated to just above the melting point of its crystalline form, would clusters of atoms in metal solidify as soon as they were in an amorphous arrangement with a melting point slightly higher than the temperature of the molten metal?

Or would you have to let it heat and cool repeatedly, perhaps while bombarding with radiation to disrupt the formation of crystalline structures or by only cooling it to the melting point of the crystalline form?

I've been looking into biochemistry and I was reading some laboratory job descriptions, and almost all of them mentioned working with lab mice. I know I won't be taken seriously for this, but are any harm caused to them? Because I feel like I would worry about being extra safe and caring to them, and if other people were mean to them it would be hard to suck it up. If this is how I feel, should I not persue this career?

>>8305118
If you can't imagine being able to more or less torture another living thing, then put it in a device and chop its head off, then pick it apart, no, you shouldn't consider that career.

This is my dilemma as well. Very few cases where there's a feasible experimental design that doesn't involve damaging or killing the mice to have the means to get at the data you're after.

Is 0 considered a term in mathematics? I know it is considered a number and numbers are included in the definition of a term, but here's what happens if I consider 0 a term.

If I were to say 7 - 7 = 0 has 3 terms, then I should also be able to say that 7 - 7 = 0 + 0 has four terms, and in fact, despite not being able to see them, there could hypothetically be an infinite number of zero terms on either or both sides of the equation, meaning I could say that any equation, including 0 = 0, has an infinite number of terms in it.

Has anyone ever been in a time loop while on drugs? Something very strange happened to me. I was doing mdma for a couple of days and then took some laughing gas, then some more. Then it happened.

>wake up from black out.
>everyone around me is in a one second time loop.
>music is also looping
>wall looks like a fractal portal
>somehow think god is inside watching me
>fast forward one minute
>people slowly start to get out of the loop
>music plays one

anyone experience something like this before? can anyone explain this?

one time i smoked salvia and thought everyone around me was cardboard. When one of them tipped over, i freaked the fuck out.

Not necessarily when I'm on drugs, but I get really bad episodes of deja vu. Every 2-3 months, I get long periods of deja vu that will last for 1-2 minutes.

i googled a lot about people being stuck in loops but nobody on the internet seems to be stuck in a one second loop. it was very difficult to even recognize what i was in. it was not like ah, i have done this shit before. i talked about it with friends and i think my short term memory was just not functioning or the imprint of one moment was so vivid it just dominated everything else. maybe it's an effect you have when suffocating? i just don't know. but it did not feel like i had experienced things before. it was one moment, over and over again except me knowing i was stuck and the hallucination about the wall that was not stuck.

>every electronic device has been turned off
then how did you measure the spectrum?
What did you use to measure? Is this sound or radiation or what?
It's clearly not resonating, w/e it is. It's a very small signal, probably noise from the internal components of w/e you used to measure.

you can calculate what types of standing waves you can get by measuring the lengths of your room. This is primarily used in acoustics, but is also equally applicable to EM radiation.
>>
If every device is off then how did you take that spectrum?
>>
Its a sound. It has been bothering me for about an hour now. I used my phone to analyze the spectrum. Its not coming from that.
