>it's actually just a simulation

Given that the overwhelming majority of chemistry and catalysis is subject to the law of conservation of mass, dimensional analysis (and by extension stoichiometry) are the foundation of the field. Do you really expect an introductory survey course to teach you cool reactions without first providing the prerequisite knowledge needed to understand them?

As for the eye, the believed theory as of now is that it started with a very basic light sensitive cell that allowed very, very basic sight. Obviously, this would naturally improve over time and led to the eyes we have today.

Panama boi here
>- How long are you exams?
2 hours
- Do you have midterms?
Yes, like 3 or 4 that count for 40% of the grade most of the time. Except one time a professor decided they were 0% and final was 100%
- What grade scale do you use?
0 to 3
- At what % do you pass/fail?
You pass at 71%. Fail at anything below that

In the end you can be allowed to pass a course with a 61% if the professor thinks you are worthy but you are basically in academic probation and any other fail means you are out boi

- What kind of things are you allowed to use during the exam?

Math major here and they let us use calculators and flash cards with professor approved theorems. That means high school tier trig identities that are not worth to memorize.

However once a professor allowed me to use my cellphone in a test because I didn't bring my flash card lol. In the end I didn't even use it though. I will note that only I was allowed this, this isn't a normal thing.

UCL in UK here
>How long?
about 2 or 3 hours for maths exams
>midterms
for some modules but they are only worth ~5% of our grade and are mainly practice
>grade scale?
Same throughout the UK, 40% to pass and the highest grade, a first, is 70%
>What are we allowed to use?
Nothing normally, sometimes a calculator

>>8536426
>71% to pass
I actually like that. There are people in my class that barely know how to do basic integration, and it kind of makes me upset that these people are worth the engineering title after 3 years.

Seems like your exam rules arent so strict, as we face a fail + one to two year suspension from any exam in higher education if we get caught even with a phone on us during the exam (or any breach of the exam rules).

>>8536436
Seems a little weird to have >70% for an A and then the rest of the grades B-E in the range between 40-70%

> is it to make a small supersonic plane powered by electricity?

Figure it out yourself.

We are not your wetware CPU's.

I remember reading about a material that when water droplets move across the flat surface, it will generate electricity. Build the exterior out of this material, and at supersonic speeds it can power itself when passing through clouds.

>>8535887
thats basically drawing a small current from frictional forces.

>>8535819
supersonic speeds are achievable by combustion because it gives tons of energy in heat and pressure to a gas, how would you do the same with electricity?

I'm not sure if its possible to accelerate air beyond supersonic speeds using a propeller.

>>8535641
It would cost more to reabsorb the carbon than to simply not release it in the first place. You're paying for it right?

>The real reason why liberals push climate change is to retard the economic progress of 1st world countries through energy restrictions so that 3rd world countries can surpass us.
So 97% of climatologists want their own countries to suffer economically?

And yes I saged this obvious bait.

OP is a fagot

How do they deal with poop dick?

Is giving yourself a full anal enema simply part of the daily hygiene routine for a gay guy?

Is poop dick why they're always so anal about their diet?

Always wondered.

>>8533963
It being pleasurable ensures the survival of our species, its instinct basically

>>8539167
Well one of the reasons is that Saturn is massive as shit, hence great tidal forces will appear in any object near enough, these tidal forces will tend to dismantle anything that tries to agglomerate near it. There should be more explanations though.

>>8539167
They aren't massive enough, moving fast enough, or localized enough.

>>8539195
Thats true for any single band within the ring, but Saturns rings are also incredibly wide and each ring is uniformly distributed.

Do the rings define a zone where coellescence isnt possible due to tidal forces and past the outter most ring is where coellescence is possible?

Uh errm, this is missing.

>>8539086
That is neat

>>8539086
Wait so you made an equation that gives you how more likely blacks have to be caught for the same crime ration compared to whites assuming both are equally likely to be criminals?

>>8539001
Yes

No.

Maybe.

Does the pulley have mass?

no, nether does the rope

>A jew that can't do math
Kill yourself

OP here.

Just thinking, if you can map the half space where a<0 to a circle, surely you can map the half space where a<1 to a circle in a similar way. Or more generally the half space where a<n. Could you then let n tend to infinity and map the entire complex plane onto a circle?

>>8538655
>How would you go about finding such a mapping?
w=(z+i)/(z-i)

>>8538655
>The surface of a half sphere, as I understand, is topologically equivalent to a circle

I'm currently taking a course on complex analysis, so I'm not an expert, but, I think this statement is wrong.

thats a baby's understanding of game theory

>>8538252
All mathematical models are essentially wrong, but some of them are useful.

I believe the word "Autism" itself has to do with it. Isn't it basically a PC term for mildly retarded?

On the next episode: Is darkness really just the absence of light, or is it the other way around? Or both? Or neither?

>>8538123
To explain light there is photons. That is how you know light exists and darkness is a lack of light, not the other way arround.

Since there is no particle of heat like what the photon is to light, we simply set an arbitrary point of view to explain thermodynamics.

The fact that you can just change + for - and - for + in every equation of thermodynamics and the results will still be the same proves that heat or cold, cold or heat is just a matter of perspective.

Just as you can say that hot things are excited and cold things are not excited you could say that cold things are calm and hot things are not calm.

Coldness is forgotten, deemed as the negative, and warm is considered the positive, when from the perspective of the truly cold and lonely particles, it is the warm and happy ones that look negative.
