So I am considering returning to my mechanical engineering program this spring. Thing is, I fucking hated it and sucked so bad at it when I dropped out. I will never make a good engineer, so this will just be for the piece of paper so I can get my foot in the door of the jews. On top of being a brainlet, I am a poorfag who will be taking public transit 3-4 hours a day, same as before. How do I get through this for 2+ more years without constantly thinking about offing myself?

Why do you take public transit for 3-4 hours a day are you really an hour and a half away from school?

If I have a process Xt ~ sin(2*pi*u*t) where u is uniform(0,1)

For X1 and X2 can I use the integral of sin(2*pi*u1*1)*sin(2*pi*u2*2)du1du2
to calculate the joint cdf of X1 and X2?

Or is does it matter that Cov(X1,X2) is not 0?

Where did you pull that stochastic process from, it's fluctuating as fuck (no closeness conditions on the increments from t to t+du)

What do you really compute when you integrate over the value of the function of u, not the probability density function of u? Or Is that really a cdf?

How come we still don't do more research on Trepanning? It has been done for thousands of years and is said to have so many positive effects. It's like brain overclocking, yet today it is mostly forgotten. I don't even think there are any negative effects, really. There is close to zero risk with modern surgical instruments.

Gross. >>8634101 speaks truth.

Oh, interesting. Your picture reminded me of modern day idiots who drill holes from their nose to their brain so that more oxygen can reach their brain.

I was trying to look up the name, and I think it is called "Trepanning" as well.

Anyway, yeah, that's a stupid idea, and, if you get infected from this hole, you are kind of fucked.

>>
>>8633795
Assuming you use high level programming language, the code segment is generated automatically by the compiler and you don't even know about it.

If you are programming in assembly and don't know this, just quit it and pick some book on x86 assembly from times where such stuff didn't exist. I recommend you Art of Assembly by Randall Hyde.

This is not computer board tho, see /g/.

Is chaos essential in science and math? If you believe so, why must we have things that occur that do not follow the laws of math and science? Is chaos legit or just somethings we can't quite explain right now?

I think chaos it is a result of factors in our universe that exist yet cannot be observed / measured by us. Perhaps with time we will be able to measure and accurately calculate chaos, the implications of such would be earth shattering.

Why does a physicist, a computer scientist or a biologist need to study only a few years to complete their training but any field in medicine needs a lot of years?

Is it because medicine is the most advanced science in humanity right now?

because medicine students are retards that need 10 years to memorize all the stuff to be part of a ponzi scheme.

Why (or how) do we have the ability to observe the world?

What I mean by observe is that your brain is not only providing you with a feed of sensory information, but also information on your thoughts as well. The world is deterministic, so your thoughts are not a product of free will, but are the result of physical processes in the brain. Although you may feel as though you are controlling your thoughts and behaviors, you (the observer) are really just observing the information received by the brain and its response to that information.

What function does this observation provide?

>>8633395

Absolutely correct. That is why illusions exist. What you are describing is perception.

There is too much information for our brains to physically interpret fast enough, so our brains much choose what to focus on. That is the reason it must use perception.

You should read some neuroscienc and/or psychology. Biology is amazing.

>>8633395
What makes you think it has a "function" or is useful at all?
>>
>>8633821

Because evolution has optimized shit for billions of years.

Most humans agree the brain is pretty awesome too.

The creepy reality about that technology is that it effectively kills you every time. By disassembling all your molecules, it effectively makes you completely dead for that moment, and then it puts you back together (possibly with the use of completely different molecules, but even if they were the same, it would still be a dead state).

However, something even creepier is that that might be happening anyway as we speak. Due to quantum indeterminacy your molecules aren't exactly stable. It comes to reason you are constantly in a state of death and life.

Truthfully, is climate change an issue that we should concern ourselves with? I tend to get mixed messages when reading about it. Does anyone have any good evidence for or against climate change being an issue.

"proof" is always something that isn't easily accessible because it's either behind paywalls or requires prerequisite knowledge of scientific method in the particular field

the easiest way is just going on wikipedia and browsing through the sources

if you couldn't be bothered researching then just accept that there's a consensus in the scientific community that it is fact, and such things don't happen without sufficient evidence

How would you find x? Not necessarily a value, but at least an interval. I was thinking about using the Hinge Theorem, but we don't seem to know anything about the angles unless I assume [math]\angle ABD > \angle DBC[/math] just because

Why are there no programming languages for analog computers?

There were, just specific to that type of machine. A language is just what you do to compute a function.

Analog computers serve a single purpose, so you don't need much of a language to program them
>>
>>8633036
How would you reliably represent characters in analogue? How would the compiler look?
