Tell me everything I need to know about measure theory.
>>7787723
Measures exist.
A few things to look up
Definition of a sigma-algebra, of a measure, of a measurable function.
Some constructions (product measures, push-forward, Caratheodory)
Properties of the Lebesgue measure (regularity, behaviour under diffeomorphism)
Construction of the integral relative to a measure
Lp spaces
Riesz representation theorems
Radon-Nikodym theorem
depends what you need it for. if you only want to know the gist of it to bring it up in your autistic name-droppings, you have to realize that it is a way to formalize the whole aspect of "defining length", and from there, the fields of probability, integration, analysis fall out.
For example, you can learn a good amount of Markov Chains without knowing measure and freely using Fubini to justify interchange of integral and summation(for integrable functions).
its a very dry field and you start from "basics"(sigma algebra, borel sets), and work...

"a" of course, you only use "an" when it either starts with a vowel or does phonetically sound like a vowel

If you're 14 years old and want to be a pretentious pseudo-intellectual autist, it certainly is.

Yep. Read at 16 y.o. never looked back. Funny though, the Philosophy Majors thinks that's impressive, but really the book is very basic when it comes to a mathematical understanding.

yes it's fantastic, it's slow going though.
Can /sci/ recommend me some essential textbooks for energy engineers? (Especially for renewables)
>>7787604
>(Especially for renewables)
Do you want to know about the electricity grid or do you want to know how various generation systems work?
>>7787646
Both are fine senpai. If you can recommend about smart grids, power transmission, storage systems, pv cells, fuel cells, wind generation, biomass etc I am open to anything useful

sorry to highjack your thread, but you seem to have a neuroscience background (which i find pretty interesting). is it currently possible to selectively and reversibly "switch off" specific brain functions like seeing or hearing in lab-animals?

Fairly sure that counts as cruelty.
Hey /sci/, can I get a recommendation for good textbooks on the following subjects:
- Probability and statistics
- Econometrics
Preferably those that I can download for free from the Internet.
Thanks.
nothing that you download for free will be good really
What do you mean? The Macro and Microeconomics series by Mankiw I downloaded are pretty good.
>Probability and statistics
A First Course in Probability (Ross)
>Econometrics
Econometrics (Hayashi)
This assumes you have no prior experience in the subject, but are willing to make a serious effort to learn and do not recoil in fear from mathematical symbols.
Hello, /sci/.
I come to you today as a beggar. I need help reconciling some data in my head and I just can't seem to explain it to myself in a way that makes sense.
I'll see if greentexting can keep this succinct:
>Need weekly average of "units per hour"
>Create simple formula to calculate each day as though it was given 4 units of quarter-hour time (1 hour)
>Then average each day over a week, expecting an accurate average for the week
It...

>Averaging each day evenly should then return the same result as the week's total units divided by the week's total time, but it doesn't. It's not even close in some cases.
A weighted average would
You need to weight your mean with the time for each day.
>>7787849
Right, I understand that's how to arrive at the "proper" number. What I'm having trouble with is understanding why the method above doesn't work.
It makes sense in my head like this:
>Find each day's quarter-hour average: the number of units divided by the time
>Multiply by 4, giving the number of units that would have been produced in 1 hour at that rate
Now, here, I figured the weights would shift...

went through everything multiple times but lack a stack of 'exercises' because that's what really hammers the stuff in. searching for publications and rationalizing the outcome on my own seems too overkill time wise, so no idea where I should really get practice from to be able to apply the concepts of conformational analysis in harder settings

yeah that will happen, this MIGHT be useful

perhaps the best approach is to look through some notes by a different author
the Boger notes for example

Hello, this is my first thread on /sci/, and I felt it was appropriate to ask this here. After which I will continue lurking.
I was wondering what /sci/ thought about aspartame - that chemical in diet drinks an all that jazz that everyone swears up and down causes cancer, but then alot of other people say it doesn't.
I am a type 1 diabetic, and I drink alot of diet coke(it's actually one of the few unhealthy things I have in my diet)and I can't decide if I should cut it out or not.
Thanks,
-anon
>>7787435
if a lot is not 1 liter each day, drink it anon. you are already fucked
So explain to me what about Diet Coke is unhealthy. It's just water, flavoring, phosphoric acid, caramel color and aspartame.
>>7787435
just fucking stop drinking soda
it tastes like shit and gives you the worst crashes ever
if you want energy drink coffee or green tea
So, how does /Sci/ tune their constants in control systems?
I have no idea what any of that means.

Hey /sci/
Given that mental illness represents a tangible defect in the functioning of the mind, does it not stand to reason that we've evolved some mechanism of recovering from these illnesses, since we the body has regulatory mechanisms which attempt to deal with most of the other illnesses?
Could mental health practitioners achieve better results if they knew about said mechanisms and could work to maximise their effect?

No, but the body immediately floods the site with clotting agents and immune vectors to minimise further risks, eventually turning the wound into scar tissue for structural integrity and to keep bacteria and shit out.
