Stupid questions thread, for the things Google won't give you a good answer for.
What are the causes and implications of wavelengths of light?
I've never really come across one good explanation, all I can figure is that it probably has something to do with certainty of position.
>>7709400
What do you even mean what is the cause of the different wavelengths of light? Wavelength is a property of waves.
>>7709400
>What are the causes and implications of wavelengths of light?
This right here. This shit.
If photons truly are particles, is this particle as a whole the "electromagnetic wave"? Isn't there no actual difference between electric and magnetic fields? Is the flux observed in this what gives the frequency and wavelength?
Is all this shit just explaining that light is its own deal, and not simply observing the fluctuations in the aether?
Seriously, what the motherfuck is going on? I know how radiation behaves to some extent, but what is it? No longer am I willing to interpolate the answer. I get treated like a fuckhead when I extrpolate. So go on, what the hell do we think it is this time.
Is this place a meme? Considering to study there for engineering, but nobody in my area knows what it is. Is it worth OOS tuition?
What determines if a fuel is better for a combustion engine or a diesel engine? What are the properties that need to be examined? Thanks
>>7734781
Probably something that can burn quickly
>>7734785
Wtf does that mean? Auto-ignition? Flash-point? Energy density? Which of them is important in the design of an engine?
Petrol ignites via flame or spark. Where as diesel ignites under pressure. Notice how diesel engines don't have spark plugs or leads?
I'm curious, were any of you or your family put into "gifted" programs when you/they were in school? Do you feel that it's positively or negatively affected you/them in an academic or emotional manner? Was the affected person among the guinea pigs of the curriculum or had it been used for some time?
I'd like to research this further and want to get some responses from people that aren't directly around me.
it was just some bullshit to get out of class occassionally
>>7734276
Okay, did you miss anything important? Was that the extent of the program or was there an entire curriculum for students later?
I was in Enriched Math in Highschool, which was pretty pointless because we had the exact same curriculum and exam as the normal stream, we just went through faster/did moderately more challenging questions. Honestly I thought it was a good thing, helped me adjust to Uni course load easier
Will we have matrix like virtual reality by 2030?
I just wanna commit home invasions and play surgeon.
>home invasions
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.
>>7733887
>we live apart from each other.
Have fun being cucked.
>>7733887
She's absolutely cheating on you.
is P = NP?
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/: What are your views on the field of philosophy?
Absolute bullshit for people that can't apply logic or thought to anything meaningful.
Le to be or not 2 be xDxDxD so quirky and liberal and smart
>>7733854
>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 rather than the dumb normies who got shit school grades.
Also another way you can tell that /sci/ goes to bad unis is when they boast "99 % of my CS101: Java Syntax class failed." How the fuck is this a boast? The shitter universities have higher drop out rates (a few exceptions, when they take many people but weed them out, but this is rare and mainly very prestigious nationalised institutions). Hard working students almost always pass. If a Harvard guy goes up to me and says "99 % of people passed CS101" I'm not going to see Harvard as shit.
When I once posted a problem from the first year Oxford maths course on here as a way to troll people at worse universities, I got tonnes of abuse.
Also I'm not an Ivy league guy. I'm a guy who went to a uni ranked 100 - 150 in the world and I am as butthurt as anyone can get. My anus is redder than a cherry dipped in blood. Don't think I'm trolling. Also there are very few exceptions to the stuff I say: I mainly think of Germany, or other mainland Euro countries (not France), where I think there is more equality due to government intervention or something (or maybe we just never hear about them).
>inb4 only grad school matters
Yeah, sure, 4 years of the difference in quality I talked about contributes zero difference to grad school performance...
>>7732758
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.
>Dropout rates aren't high at prestigious universities!
Wrong:
https://en.wikipedia.org/wiki/Math_55
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.
