Oi /sci/. Why the hell is a black hole so mysterious? Isn't it composed of 3D matter that piled up so densely that it even sucks in light. I know that gravity is still mysterious. But is it only mysterious because people don't see what's inside?
>>7752606 I don't think its really "Mysterious" yeah, you can't see inside it because light can't escape. What seems odd to me is this:
Lets say a star with a mass 100x the sun collapses into a black hole. It still has that same amount of mass, any planets orbiting that star should still orbit it normally, yet light can't escape? How could the light escape when the star was still a star? I might be missing something or not taking into account something
Why does the sum of all natural numbers equal -1/12?
From what I've read is that it is a 'reduced version' of the actual answer, which is infinity. The reduced version is apparently useful in physics e.g. string theory. I know approximations must be made when doing science but this one gets me uneasy. Maybe the expression should be changed to '≈ -1/12' or am I being autistic about this?
'=' denotes any equivalence relation. people don't use weird squiggly symbols generally. it's no approximation, but "analytic continuation" of a function. It's like saying the geometric series is equal to 1/(1-x) and then continuating it so that the geometric series at 2 is equal to -1 (where it is, in reality, infinity)
The 'natural' answer is that it approaches infinity. More specifically infinity to the second power. So lets say you have 1 + 2 + 3 ... + x. When you have really large values in x, the sum is approximately x^2. There's some series that you can expand it into, don't know if I have the picture, but when you do it you'll get x^2 - 1/12 + something/x + something else/x^2 ... So, when people say that -1/12 is the answer, where they get that from is ignoring not just the infinitely small parts, but also the infinitely large parts, and only looking at that one constant, -1/12.
The most concise way to put it is -1/12 is the acceptable answer in higher levels of mathmatics. You can do more if you can reduce infinite series into constants than you can if you can only say things like 'yep, that's infinity'
Why bother pretending that you can contribute anything to science or mathematics when people like Terence Tao exist, who can do your life's work in a few weeks? To pretend otherwise is extreme narcissism. I put my recycling in the correct bins but to pretend that have any meaningful effect on the environment when the USA and China smog the place up would be deluded.
Also take in to account three factors: Smart people breeding with each other, increasing world population, and increasing parts of the world that have access to higher education. The number of Terence... Comment too long. Click here to view the full text.
Jobs are a bit harder to get, that's about it. I highly recommend it, though. Just do outstandingly well in it, do a lot of internships for free, make a good resume. You probably won't earn as much, but if you're interested in it, that doesn't matter. I'd strive for a job at some observatory on Antarctica, Scandinavia or Chile
/sci/ I think I might be stupid. I've had the thought lingering in my mind for a long time. How can I know if I'm stupid? I have a problem with speaking that gives me a strong suspicion that it's true. I have difficulty with communicating complex ideas. I have to take it one idea at a time. All my concentration is going toward one idea and my mind is just completely consumed with how to articulate it. All my mental functions are basically just focused on one thing which is articulation. When I see other people speak it seems they can hold multiple ideas in their... Comment too long. Click here to view the full text.
>seems they can hold multiple ideas in their head simultaneously and are processing what they'll say next while they're speaking. They can't and they aren't. They may have a vague notion of whatever it may be they are talking about floating in their mind, but you can be sure that they are not structuring their answer in any way.

What is root of minus four multiplied by root of minus 9?
There is this faggot teacher at my uni that keeps bugging us with this question.
From my point, in elementary school we would say, it does not exists as number, in high school it would be something like 2i * 3i = -6 and at uni it is still unidentified since we dont define "i" as square root of minus 1 but as i^2 = -1.
So what would be the most logical and simplified explanation of this?
>>7751976 Abandoning "realism" would essentially mean abandoning science. "Realism" is the principle that something real exists - that there exist things with an existence independent of our own minds and representation schemes.
From Wikipedia: The physicist's Realism is the claim that the world is in some sense mind-independent: that even if the results of a possible measurement do not pre-exist the act of measurement, that does not require that they are the creation of the observer (contrary...

Assuming we get to merge are minds with computers and live for billions of years could we create a time dilution effect and make is so that say one second in real life is actually a year in computer world?
I wonder if it's possible to use lust as a motivation for doing productive things like studying. For example don't jerk off for a few days and then every 15 minutes of studying allow yourself to jerk off but not cum for 1 minute. I wonder if you would just be distracted while studying, or if you'd overall be more motivated to do it. Does anyone know of any experiments preformed on this?
