USA here.

Today my Calculus II professor mentioned that in Europe (He's European) they do not use sec, but rather just 1/cos.

Just looking for conformation on this, and if so why? Is there some advantage I just don't see?

The wiki says that Chemistry the Central Science is the best textbook for a beginner. However I've heard others say Zumdahl is better. Which should i use?

If you know calculus and you have a strong passion for chemistry, just start by using two books: Chemical Principles by Atkins and Principles of Modern Chemistry by Oxtoby. They're hard, but focusing on one book and reading the other book for alternative explanations and extra problems will give you a solid intuition of general chemistry. The best brainlet book is probably Chemistry: The Central Science, but it's quite mediocre, and it doesn't get better than that for other similar caliber books.

All of the other general chemistry books are mediocre at best, and even these books could use a fresh method of presentation of concepts and connections, so searching too hard for the best general chemistry book is going to be a fruitless exercise. You're better off diving into what I've mentioned and pushing through to the more specialized areas, where the texts are far better. Clayden for organic, Macquarrie for physical, Lehninger for biochemistry, Miessler for inorganic are all fantastic, so there's light at the end of the tunnel.

I dont have it anymore, but someguy made a thread a year ago where he made an extremely detailed rape simulator. Everything from different genomic crosses to amount of vaginal wall tear from repeated abuse.

You could build houses block by block, sneak around (stealth system), etc.

appreciate the contribution.

I'll start with the few I know:

-Women are better performers socially. They can utilise a social power which could allow them to outperform men in social tasks. Very useful in professional environments.

-Women are accepted by strangers more easily than men.

-Women are generally more trusted than men

-A women may do everything a man can, and more - girly things men couldn't do.

So, these privileges I was talking about mainly benefit women in social ways. Sprinkle onto the privileges confidence, wit and charm and you will have no reason not to achieve anything you set your mind on.

Am I missing any privileges and does anyone have anything to add or rebut?

I know this may sound weird but here we go.
Lately I needed to write a presentation in physics, when I started diging into wikipedia and learning about quarks and quantum mechanics, I got really intrested.
I also enjoyed watching vsauce and channels related to science.
does abybody have any recommendations regarding books/other media like videos about phsics, chemistry, astrophysics, biology, technology, medecine etc...?
I really do enjoy these topics so any help would be appreaciated.
btw sorry for my bad english im from germany.

There's a great youtube channel called "looking glass universe" which has some nice videos about the essence of quantum mechanics.

So wait, if you can induce an electric current by spinning a magnet and inducing a current in wires, why don't you just hook up a generator to the crankshaft of an engine to power the car instead of using a battery?

I wouldn't. All "proofs" I've seen involved division by zero.

1 = 5 (mod 2)

we have ~80 years to live at best if you live in a good country with a decent lifestyle

do things you enjoy or live to regret all the things you didn't do on your death bed

70-80 can hardly be called living.

>>8994283
To contemplate the logos. If you don't enjoy that, then don't study science. The last thing we need are more pseuds.

I honestly like conservatives more than liberals when it comes to science. All the greatest scientists that made useful contributions were conservative and pro war, like Edward Teller, John von Neumann, Ernest Lawrence, ect. Liberals are honestly the anti-science group. The stuff they care about is useless. Evolution is useless, and vague, and all fields based in it like evolutionary psychology is beyond retarded. Don't even get me started on sociology. They hate bioweapons research, and genetic engineering, and nuclear research, ect. They care about stuff that's not well understood, like climate science, and declare war on fissile fuels, instead of coming up with a solution. https://e-reports-ext.llnl.gov/pdf/231636.pdf
