Not science.

Can we go back to the flat earth thing? Because that's less retarded than mbti

Kinematic models are used a lot, but there's definitely full dynamical models used.

Are self-driving simulations constrained by physics simulations in any way? Where do you see avenues for improvement?

>>8971968
> Where do you see avenues for improvement?
optics and image processing
machine vision is so incredibly behind human vision
Rain, droplets on lenses, and changing lighting conditions all mess with optical sensors.
I never got into it, but I thought that fault detection and correction was something cool to get into.

> Are self-driving simulations constrained by physics simulations in any way?
pretty sure car physics simulations are pretty strong.
I've worked with quadcopter simulations where they have to deal with the airflow effects around the ground and walls, which seems far more complicated than cars.

If anything, they might still do some airflow effects for higher performance models, but I don't see this happening. Models only have to be so good to be useful.
Maybe snow, rain, ice, muddy, and leaf conditions. I've been far away from self-driving car literature too long.
Your pic looks like tech I've seen for a decade now

What are you, some sort of humanities major?

I am. I-it's a good humanities degree, though.

Here are some books you might find useful:

How to Think Like a Mathematician - Kevin Houston
How to Prove It - D. J. Velleman
Mathematics: Its Content, Methods and Meaning - A.D. Aleksandrov, A.N. Kolmogorov, & M.A. Lavrent'ev (optional but still informative)
The Art and Craft of Problem Solving - Paul Zeitz (optional but still helpful)

>>8971798
Try going through the first few chapters of Tao's analysis I. It goes over basic material, but asks you to prove everything rigorously. Might be good for you

>>8971798
Real analysis is a rude awakening for everyone. And if you only like math as it pertains to physics, I wouldn't blame you for struggling with abstract algebra.

>Is there scientific evidence for its efficacy?
Yes. DBS in Epilepsy patients improved memory by a significant amount.
>If so, is there any reasonable mechanism behind its results?
No, its fucking magic as far as we know.
>Does anybody here have any personal experience wisth their own EEG kits or with dedicated clinics?
They're shitty kids toys, you might get alpha waves and you can use that to help you meditate or some shit but it's a very crude feature.

>No, its fucking magic as far as we know.

I've heard that random settings can be as beneficial as deliberate settings.

>They're shitty kids toys, you might get alpha waves and you can use that to help you meditate or some shit but it's a very crude feature.

I'm talking about Q-Wiz kits with multiple channels that cost at least $1000-2000.

>>8971845
You could save yourself the $2000 and take up Yoga or something for the same effect with the same amount of scientific backing.

Outdated, much like "systems theory" which came before it. Their methodologies and key results have quickly become obsolete.

As a general rule, any field that tries to christen itself with a general-sounding name, will tend to underdeliver in terms of tangible knowledge gained.
For example, consider "artificial intelligence", the hot new trend right now. The theory, models and technology have been around since the 1990s; the only thing that's changed is that said technology is finally cheap enough for distribution to the masses.
Fifteen years from now the subject will fade back into obscurity, just as the dot-com bubble burst fifteen years ago.

If you're better than me at being good at not sucking ass on python I'd like your help

wtf are you posting this question this board for
yeah ur rearded

go practice programming and figure it out instead of shitposting

did you try killing yourself?

2^2 = 4 = real
i^2 = -1 = real

Some squares are real

then it's settled. Squares don't exist.

one of my tutors said chaos theory was his favourite class, that's all i know

>>8971644
took a class on chaos theory from strogatz himself, was pretty cool.

dont know much about the field as a whole, or what sort of research is being done.

""""Chaos Theory""""" is what normies call Nonlinear Dynamics. Enjoy using numerical methods to solve a bunch of ODEs/PDEs. All you need to know is that chaotic systems are very sensitive to initial conditions, and now you should KYS

>>8971623
no it doesn't. it just mean you need a much smaller n to get a good approximation

>>8971631
Alright thanks

binomial distribution is discrete, normal distribution is continuous, so even as n approaches infinity, the normal approximation won't be equivalent to the binomial.

>>8971566
No, I heard Gauss once proved them but they're still not fully proven.

remember that science is just a list of facts you can debunk by using high school rhetorical debate devices

Linguistics professor. That way you can instead argue with to-be english major drop outs.

No one ever used to whack me in the jaw with a hammer when I was in not poverty. Those were the days.

It depends on the individual. In terms of employability a linguistics degree can vary pretty wildly. Some schools require that linguistics grads be moderately proficient in at least two non-english languages before graduation which vastly improves their market value.

I know a guy who did computational linguistics and now he works for a quant. My girlfriend's cousin got his undergrad in linguistics and went on to graduate school for speech therapy, and now he makes decent money doing that.

Like any degree there are jobs available, but many of them aren't in linguistics. If I was studying linguistics I'd probanly pick up a CS minor or something as a fallback so you can effectively convince employers you're a CS guy without having to degrade yourself by actually being a CS guy.
