Is it a realistic solution of the fermi paradox to assume that all intelligent species develop life like virtual reality earlier than viable interstellar travel and therefor just stay on their home planet for ever playing the Gods in their comfortable computer simulations? Because that seems the most plausible to me
How much Trig is in Calc I? Do I need a Trig class beforehand? How much Calc is in Physics I? Will I need a Calc class beforehand? Sorry if this is a dumb question, my schools advisors have not helpful.
>>8418663 >How much Trig is in Calc I? Not a whole bunch. So long as you have taken a pre-calc course you should be fine. Calc 2 on the other hand has a lot of trig, generally speaking.
If you're completely oblivious to calculus and your alegebra is so-so you it might serve you better to take calc 1 first, albeit the calc isnt that rigorous. But if your algebra is on point you could get by taking the two together.
>>8418663 >Why do Americans need an entire university class on trigonometry anyway?
I have never heard of a school offering Trig as a seperate course in my school district in the US but i have heard about it before. I think it was originally a secondary track for those not able to do pre-calc and calc. Algebra 2 covers trig very briefly and in pre-calc you really get the full trig treatment. So, for those not taking pre-calc learning trig is really helpful for real world application.
I tried to read the original article by Witten about the Witten effect. I realize that I had to pay 30 dollars for the article. >Fuckthisshit.jpg Find out about Sci Hub (arxiv has been my friend for too long!) Find out about the "controversy" regarding the legitimacy of Sci Hub. Some guy wrote "to steal is to steal." Go to my article published on PRD. I realize I have to pay 25 dollars. Use Sci Hub to get my own article (it is on the arxiv, but I just wanted to see the "published" version.)

Talk about keeping a low profile! The fuck is he waiting for? a public demonstration of these materials would make him into a living god. how hard is it to get your patents and trademarks straight? Could he be lying? but why?
I dont know why i like it. I remember as a kid i could memorize all the countries, rivers, oceans, islands and cities. It helped me win 4th in the state geography bee in 6th grade. I still don't understand how i could this and yet be a utter failure at all other subjects (SS i do well in, Chemistry as well). I was diagnosed with Autism a few years ago and the psych told me autistic people are naturally drawn to memorizing random things. For some its numbers or... Comment too long.

According to the multiverse theory, there are infinite amount of parallel universes with infinite amount of possible outcomes and variatons. I deduce from this that there should be an universe, that at this exact moment of time, would open a wormhole to ours' and destroy all of existence. If the theory truly is true, then why isn't this happening.
one can exhibit the will to survive through fierce adversity wouldn't you agree? It is rather logical/instinctive. There's a flip side to that coin that will always be there I believe, even if you don't want to see it.
We like to talk about heroes and leaders, which are prime example of survival instincts taken to the extreme. This would make no sense without the other end of the line. Each segment in time/space has two ends, humans are no exception
If you're doing scientific computing, post which programming languages you know and the type of work you do.
I want to learn a language for scientific computing. So far, my computational experience has been with computational packages and I want to move on to making my own programs. I've had experience working with FORTRAN for simple Newtonian modeling and I know how to use Matlab (which isn't really useful for fast number crunching iirc).
I'm already familiar with Linux and computing clusters. Just the language.
Lets say you have a universe consisting of 2 binary bits, the binary bits, a split based on whether or not a bit changes, and in this universe, it always happens in the order from left to right. There's a 3rd binary l/r that simply represents if it is the left or the right bit's turn to change
So the base universe 00 l
splits into 10 r 00 r
splits into 11 l 10 l - 01 l 00 l
Splits into 11 r 10 r - 01 r 00 r -- 01 r 00 r - 11 r 10 r

>>8417731 >A fermion needed two full rotations, 720 degrees to come back into phase. Think of fermions as being connected to the world with thin invisible ribbons that cant pass thru each other. rotating the fermion 360deg will give those ribbons a twist. This twist cant be undone unless you rotate the fermion back. Now rotate the fermion 720deg, the double twists in the ribbons can now be undone without any rotations.

>>8417551 Just because some of a particular organism evolved doesn't mean that all of them have to evolve aswell.
For instance, look at bacteria. Bacteria exposed to antibiotics multiple times usually become resistant while bacteria of the same species in areas that don't commonly use antibiotics don't have the resistance.
A friend of a friend of mine was a technician or whatever it's called on a nuclear submarine (not an engineer with an engineering degree.) Basically he was the guy who was in charge of making sure the reactor didn't blow up.
What's the point in science when Ivy league frat bros will always shit on you and benefit off the fruits of your labor?

>>8417321 >What's the point in science when you don't make money? Figuring things out. If you think this is about money then you're suffering from a very serious misconception. Money is not the same thing as value. Most rich people, like most people, are hollow idiots. Money has very little to do with "value". If you want to be Kim Kardashian then you should definitely not pursue science or math.
Your main concern shouldn't be getting milked by Chad. You'll be lucky to even make it that far. You should be worried about even getting your foot in the door without being backstabbed by dozens of other highly qualified scientists who will try to steal your work.

Any mathematicians starting to wonder if math is better left as a hobby and not as a career?
I mean the rabbit hole has gone so deep that most people publishing "new" mathematics don't really have any idea why its useful, what it means or why we should even care.
I'm facing this dilemma as I decide on graduate school, I have done "graduate" real analysis and its cool, same with topology - I read them for fun and I like it a lot but once you start reading research papers it sort of feels like a game without a goal and to be stuck doing...

You're pretty much right. I'd advise against pure math graduate school unless you live, breathe, and shit [math] (\infty,1) [/math] TFQT topoi (or whatever esoteric object of study is relevant to your interests). Consider applied math or statistics if you want to go to grad school.
>>8417099 This video has to be faked somehow, but it does show how retarded these word problems are in common core. Students just look for keywords and translate the problem back into a simple math question. Rarely are they given a vague problem with multiple avenues of attack.
>>8417099 I figure a big part of it is conditioning from being attacked when they say they don't know or understand something. Politicians have this issue all the time where they think they have to be omniscient and if they don't know something they should just fill in the gaps with made up evidence. The stigma on not knowing things has to stop and people need to know that it's okay to ask questions when they don't understand something. For example instead of saying global warming is a hoax by the Chinese... Comment too long. Click here to view the full text.
Working on a lab report for my biochem lab, lowkey fucked up and didn't have a chance to really work on it until tonight. Probably going to be around 20ish pages.
My TA didn't post a picture of one of my gels like she was supposed to and I emailed her days ago about it and she never responded back to me or posted it on our course site... I'm going to be pissed if they take off points for not having it. Probably just going to use someone else's picture to be safe and just site it and mention somewhere that it was never posted.
1. The Government Lies (Remember the Dress incident? With the gooey stuff?)
It's well known that the government lies, murders and steals in order to keep in control of the population. It doesn't take a rocket scientist to know that JFK's head did not explode backwards caused by a bullet coming from the book depository. So if the government would murder the president and cover it up... why wouldn't they lie about other stuff? 2. NASA has been caught manipulating images and evidence before
>>8416620 Finally someone who brings fourth a clever discussion on the big debate on "Flath Eath Theory"! People like you who make their own research and questions this mad society we live in a too few.
In my university "theory of computation" is a post-graduate course for mathematicians. I'm a CS guy so I obviously completed an equivalent course for my bachelor's degree. So I've taken "post-graduate mathematics".
>>8416411 Because dogs are the most philosophical animal. A dog doesn't like what it doesn't know and likes what it knows. So it he likes and dislikes by the test of knowledge and ignorance, which is the definition of a philosopher. Philosophers are humans of course, so dogs are more like humans than they are like chimps.
