How accurate is the novel Contact where astronauts enter black holes in order to travel to points in space lightyears away from earth?

Does stochastic calculus/SDEs have any applications in signal processing/communications/DSP? I rarely see the topic discussed outside of quantitative finance and physics.

The first five terms of an infinite sequence are 0.9, 0.99, 0.999, 0.9999, and 0.99999. Can you find its limit?

II'm already 25 and I'm about to get a Bachelor's in Mech. Eng. from a uni that wasn't too taxing, or too demanding. So I don't fully know my physics, nor maths. Since it's a sub-par uni we didn't have any labs, and since it's a sub-par country, it's very hard for a student to get an internship, especially if you're from a shit uni. I have tests remaining, and a final dissertation. Then I can begin work. Thing is, with all what I've described, you can probably guess I don't feel confident in my ability to be a mechanical engineer. I've forgotten most of what I've needed to pass my exams, because I just never had to use this knowledge apart for the tests. Also I don't actually have a knack for this shit, cars and trains are cool and all, but don't really excite me. Physics excites me, and that's why I went into mech. eng. But this isn't what I want to do for a living, I figured this out too late into my education. Salary is also not that great for the amount of work you have to put in. Would I be stupid to spend a few months learning programming and get a job as a programmer, switching streams completely? I guess I should still try out a job in engineering and see if I like it, since I'd feel really bad for spending what is now 5 years at my uni (didn't graduate in time because personal issues), without even giving it a try.

Reasons I did bad at uni are because of the way curriculum is structured. We had thrown at us in various physics classes, without even having gone over those concepts in our math class (we were literally starting out on derivatives). I was able to pass every test because in the end it never required calculus, but you can understand from this simple example I was pretty much always playing catch up, and I still do. Now that I actually do have the required math background, it'd take me about a year (alongside a mech job) to actually acquire the engineering knowledge I'm expected to have on graduating. I'll always play catch up this way.

Why the fuck are physics constants fined tuned for life?

And is not one, is like 120 variables in physics that had to be coordinated for life to be possible.

How the fuck does /sci/ /v/edditors explain this?

Has anyone ever completed a course here? Are they worth it or just a waste of time to make up your CV/LinkedIn with certifications to try to prove you know about a topic?
If you did, which course did you take and did it help you in any way?

Do we need to solve first P!=NP before we can solve the problem of concienciousness?

Does the womb of the woman holding the baby affect the DNA of the baby?

>human life peaks at around mid 20s
>spend next 50 years rotting
why is this? shouldnt the peak be closer to middle age?

Have any STEM nerd into philosophy ever wroten some philosophical essay of how God could work under our current understanding of science and physics in 2020?

I think is more a philosophy thread, but /sci/ knows more about physics and math than /his/
