Will we have matrix like virtual reality by 2030?
I just wanna commit home invasions and play surgeon.

So like, you could set this up as a paint-ball or air-soft scenario, just sayin'.

So get some fucking goats or something.

How is paintball similar to breaking into a house at 3am tying up all the inhabitants and playing games with them?
If computers/programs become self aware and we allow people to fulfil their deepest darkest fantasies in virtual reality, would that be immoral?
I mean whats the difference between fucking a child and going into VR and fucking a child thats identical similar to a real person in terms of though patterns and reactions etc etc.
However I don't see the government making it illegal to perform child rape in your own virtual reality.
So no matter how hard I try, my GPA in college has never exceeded 3.0 in the past 2 semesters.
How do /sci/ college students study?
Also, how hard is it to bump up your GPA?
I studied like a maniac before the finals. Was bretty confident that I'll ace it. Fucked up like a cuck.
PROTIP: If you do something for 24 hours strait, your brain goes into "oh shit I'm going to die if I don't fucking adapt to this shit" mode.
There were some german researchers who did a study on this a few years ago. Sorry, I can't for the life of me remember their names.
>tl;dr, if you want to be really good at something, abuse your brain with it for days on end without food or sleep.

fucking /sci/ i swear to god
My freshman and sophomore years I could not raise my gpa above 3.2 no matter how hard I tried. Something clicked for me junior year and I'm on the deans list every semester now. Being in this environment where you are constantly learning changes you for the better. You become way more intelligent than you think by going to college.
I do maths and my gf knows it. Christmas is coming soon and I'm sending her a postcard since we live apart from each other.
I plan to give her a few problems where the answer can be turned into a phrase. Do you have any cute easy problems that you like to give people who aren't that well versed in maths?
I was thinking of for example finding some math olympiad problems for 4th graders or something but I can't find any.

Have fun being cucked.

She's absolutely cheating on you.

I often view philosophy as complete rubbish. Mindless mental musing with no goal, direction, or pragmatic capacity.
However, upon expressing these views, I'm often immediately attacked with the claims that science cannot exist without philosophy. That we can know nothing without philosophy. The terms epistemology and solipsism are oft thrown around.
As someone who understands the power of the scientific method but knows little about "proper philosophy", I may be a tad biased and uninformed in my opinion. So I'd like to ask everyone on /sci/:...

Absolute bullshit for people that can't apply logic or thought to anything meaningful.

>science cannot exist without philosophy
I hate that fallacy. Basically this "argument" states "every act of thinking is philosophy". So then what is there to be pretentious about? You philosotards are seriously bragging about being able to think, i.e. something every child can do (better than you)?
>>7733854
No, but this is /sci/, where we believe that everything that is not science is stupid in order to make ourselves feel smarter.
If you have lurked for at least a day, you're either trolling, or asking here so people can confirm the opinion you already have.
I'd like to see some responses detailing your own experiences with psychoactive substances and your thoughts on how the insights revealed are certainly more notable and related to our own visceral communications with our own notions of perception of reality than other, less involved methods of learning.
I think that the subject matter is scientific enough, as it pertains to our own notions of reality and the elements that determine its course.

Is knowledge exclusive to those who can detach from the norm and view themselves from a different angle? Is one grounded perspective less honest than a multitude of ponderings without devotion?
Why was J.J. Thomson's model of the atom incorrect, /sci/?
try the homework board
>>>/hm/
It was proposed before the discovery of the atomic nucleus.
The model has electrons intwined in something like an atomic nucleus, their charges balanced out by a "positive soup" instead of protons. And I don't believe it has any mention of neutrons
>>7733786
It's not homework. Also, posting to /hm/ is the oldest shit on /sci/.
I just want an answer from you guys.
Are people who don't get math stupid?
Don't worry OP, you're not stupid.
it depends on the math. if you can't understand basic arithmetic you're pretty stupid. if you can't solve the Navier Stokes equations or prove the Riemann Hypothesis, well join the club.
>>7733472
It means they're intellectually lazy, which is worse than being stupid.
I'm a high school junior who just finished calc ii, and by my freshman year in college, I want to take a course equivalent to Harvard's Math 55. How should I spend the next year and a half preparing myself for that class?
By not posting on 4Chan and spending your time studying rather than trying to low key brag about taking Calc 2 in HS.
>>7733051
Finished Calc 2 my softmore year of HS then I took Calc 3, Diff. Eq, Stats and linear algebra at the community college. Had my associates degree by my first semester of my senior year.
I wouldn't recommend it. I was rejected from every Ivy and ended up going to a state school. At least I got a full ride. If you want to succeed, focus on padding yourself with bullshit.
>>7733143
Holy fuck way to assume the worst in someone. OP, if you really want to be prepared for math 55 kind of stuff, you'd best learn linear algebra, calc 3, ODEs, and proofs. There are resources for all of those on the /sci/ google site.
So when light travels through a denser medium than air it slows down causing refraction, correct?
So when it comes back out how does it start to travel faster again? Are the photons gaining energy or something?
Any help would be appreciated.
I would say you shouldn't think of a photon as just moving slower. In the wave picture, light is an oscillating magnetic and electric field. Once the wave hits the material, such as glass, the electric field oscillates the electrons, which in turn emit light waves. So I would say that index of refraction, which determines the speed of light, is related to the oscillation time of the electrons. If the material has a configuration such that electrons cannot oscillate with ease, then light gets emitted at a slower rate, which appears to be travelling slower.
>>7732896
Ohh okay this makes sense, thanks anon
No they're not gaining energy. Nor are they losing energy when they enter the glass.

I think there's another thread about this already
Why does /sci/ refuse to acknowledge the huge disparity in university quality? You get topics filled with people talking about their grades in Calc 1 and Calc 2 etc. You may as well talk about how long pieces of string are. Places like MIT do Calc 1 to 3 in two courses any way. And still have more content. And Caltech does proofs etc on day one. And that's just the disparity in two maths courses. Now imagine four times that difference every year because there are 8 courses, multiplied by four for every year of the degree, multiplied by being surrounded by smarter people...

Literally take nothing /sci/ says about education seriously.
>>7732758
I've actually compared the coursework of an equivalent MIT engineering degree to mine and it they have far less required courses and skip a lot of work I consider fundamental to my field. Though I do assume that the higher quality students take those courses as electives in their weird system anyway, but it should strictly speaking be required for their degree to be accredited.
They're really only good at aerospace and mechanical engineering.

You seem to care more about other peoples education than yours. Maybe you should stop being a butthurt fucking faggot and enjoy your course
What's the use of knot theory?
to tie a knot to the strings in string theory
It's to knot a knot such that it's not a knot.
>>7732643
...NOT!
Is getting a masters in mechanical engineering a good idea?
No if you have a Bachelors in ME. Yes if you have one in something else
>>7732625
What do you want to do? This is a very vague question.
>>7732625
NO YOU SHOULD GET A DEGREE IN MATHEMATICS INSTEAD YOU CAN GET ANY ENGINEERING JOB YOU WANT
>lol ur such a faget 4 studying mathematics
>shuld hav done engayneering like we smarties!
This is so funny. I was just now looking into the graduate school requirements for my 'sister' university that gives out engineering titles instead of license titles. I found out that most of them accept my degree and are 1 year long.
So let me get this straight.

>>5 year degree
what shit university is that?
All the engineering degrees ive ever seen are 4 years
>The masters literally guarantees that I would be your boss if I were to take this route
no it doesn't, an engineer with a masters and no work experience almost never gets a job. the couple of people I know who did this were turned away because they are 'overqualified' for the positions available in their experience bracket.
>>7732498
>4 years
The engineer curriculums I saw included a 9th semester that mostly had to do with law and business related to engineering. So it is not a 5th year entirely they still have to do it.
>overqualified
That is probably the one negative point of doing this. However I've seen that most people considered overqualified actually are PhDs. I mean, companies know that a masters is no more than an extra year. They can hire you without you expecting...

Once you've seen the beauty of physics or maths you can't ever become an engineer it's not possible
>tfw C+ in Orgo I
I'm never going to get into pharmacy school am I?
Why is this dumb class so fucking annoying? I can't even imagine how hard Orgo II is going to ass rape me.
>>7731820
Why pharmacy if you don't like ochem?
>>7731944
I like pharmacology and biochem. I just hate the useless mechanism bullshit of orgo and stuffing 16 chapters on one exam.
iktf lad
>B- in Ochem
>As in Physical and Analytical chem
it's literally just applying logic to dumb trends, and then getting ass raped on tests because there's SPECIAL cases that override your previous logic
fucking hated the class
