If the speed of electrical charge hasn't changed, how have computers become faster?
If you ran an electrical current through a material today, it would travel at the same speed as if you did it with the same material 50 years ago.
I thought maybe it could be one or more of the following:
>Smaller processors (less distance for the current to travel, but it just seems to me like you'd only be able to make marginal gains here).
>Better materials
>>9104546
It's indeed
>smaller processors
Which requires
>better materials
Progress in semiconductor manufacturing is measured in terms of nanometers, where smaller is better, I think we're at 4nm now.

I want you to get ussain bolt to carry a message to two places at once.
>>9104546
you have more gates in logical circuits which sort of means that more operations can be carried out at a given point in time which means that maths is carried out faster

She is the snow thats sailing in the wind!
She is the frost that sails on with the breeze!
She is the blue
Reflection of the skies
Upon which all~
-the icicles and glaciers grow more prettier colder and colder-
More beautiful the more she tries!
She is the glacier floating out to sea!
She is as soft as powdered snow to me!
Though cold she will oneday unfold.
And clearly you will see.
Her icey little wings spread free!

Is quantum physics bullshit?

being serious here
Where is the line between reality and cool theories that might never be proven wormholes, white holes, and more relevant to this thread, the multiple worlds interpretation.
>>9104512
No, it's not
There are quite a number of phenomena that couldn't be explained satisfyingly with classical mechanics but can be explained with quantum mechanics
Using quantum mechanics,you can make predictions as well, which seem to be pretty alright most of the time, which makes it not completely useless
It's much less bullshit than some of the things you've listed below

Can you do very well in academics and yet be a chad?
Let's say a Ph.D. in physics or an MD, and act like a a chad.
what's a "chad" ??
Not can you do well in academics if you are a chad, it is necessary to be a chad if you wish to do well in academics.
All of Witten's work in M-theory and TQFT (Chern-Simons theory and the rest) has been one big Chad Breakthrough
>>9104406
This, you have to be a Chad to get ahead in academia, it's all about making connections and using work from the little betas that go nowhere with their research.

Why do plants need DMT
Do it and find out sucka, nucca, cucka, fu*ka.
The real question is why do they need ethylene? And the answer to that question is to set the world on fire while tripping balls on DMT.
Probably it's an insecticide like a lot of other psychoactive plant compounds. It's easy to overwhelm the nervous system of an animal with little nervous tissue that eats multiple times its weight everyday.

What is calculus iii like?
what is linear algebra like?
Is it too much to take them during a single term concurrently?
No social life here, no vidya, good grades, just want to hear some opinions.

open a book and see
>what is linear algebra like?

>Is it too much to take them during a single term concurrently?
no, but you need to know linear algebra before doing calc iii
>>9104184
At my school calculus iii or linear algebra may be taken after calculus ii. You recommend linear be taken first?
Also, I have no suitable book to look within
>>9104187
>You recommend linear be taken first?
it's a pre-requisite almost universally, you need basics of linear algebra pretty much right at the start of calc iii

How can i properly calcularé log√ab if given that log a2=m and log b3=n?. In exchange, i will be dumping rare pepes if someone is able to solve it before an hour after this thread is posted
(1/4) m + (1/6) n
log(a^2) = m so log(√a) = log((a^2)^(1/4)) = m/4.
similarly for b

Regarding this question, would the cardinality be 125? And what would the coset representations be?
>>9104141
>would the cardinality be 125?
Why do you think it is?
>>9104141
If I'm interpreting the problem correctly, then R has 5^4 = 625 elements, while I has 5^1 = 5 elements. Cursory review also shows that the leq symbol as used in a) indicates that I is a subgroup of R (that is, a proposition whose truth value is to be determined), the triangle-eq symbol of b) means that (presumably) I is a /normal/ subgroup of R, and the R/I notation denotes the so-called factor group set, or quotient group set, given by R/I = {aI | a in R}, the very notation's definition being contingent on I actually /being/ a normal subgroup of R, in my book at least - and presumably motivating b), which context would strongly suggest is to be answered in the affirmative.
So, do we have that I <= R? Now I wonder a bit because ring entails two operations, while a group entails just one. It's also possible that I've misinterpreted the above notations a bit.
>>9104163
Close, but the notation is probably a) checking if I is a subring of R and the notation in b) checking if I is an ideal of R and c) analysing the quotient ring
