>tfw antibiotic resistance is the biggest threat to humanity
How best to avoid serious infections?
>>8165823
It's really not a serious threat, just an inconvenience. We've only had antibiotics for 100 years. Worst case scenario is we go back to not having them. But we won't because genetic engineering will allow us to create new antibiotics and other solutions.

Don't have unprotected sex.
I know, in the degenerate times of hypergamous slut culture this advice is hard to accept.
What do you recommend to start learning quantum computing?
Any books? Pages? Videos?

What is the point of wind?
You mean the role it plays in our ecosystem?
It moves pollen and other plant material around, it churns soil and keeps it aerated.
>>8165679
Forgot to mention the most important thing:
It moves clouds from over water to over land, thus bringing water to the land through rain.

Dear /sci/,
How do I prepare for graduate school? How do I make sure that I get into a good program with a good advisor? What do they look for?
Thanks,
Anon
>>8165629
Don't study in post-Brexit Britain.
>>8165629
>What do they look for?
Research potential trumps almost everything, but you can get in without it based on grades and good letters.
>How do I make sure that I get into a good program
Do your fucking research.
>How do I prepare for graduate school?
Start drinking rolling rock now so you're accustomed to the taste.

What if you're British and probably (as of Brexit) going to have to aim for Europe?
What is a good way of practicing math? I just got into CS, I was never good at math until I picked up Lang's Basic Mathematics book. I learned all that I did not learn all these years in high school, GREAT BOOK!
However, that was all in my spare time. Managed to survive PreCalculus and Calculus, off to Calc II, III then Physics. Any tips, suggested readings and routines for when you have a lot of workload and you need to understand subjects?
Thanks.
>>8165506
>Lang's Basic Mathematics
Isn't this book pretty self-contained? I had the impression that if you master it you shouldn't have any problems nailing precalc or calculus.
>>8165537
Yeah, it is a great book and I enjoyed it! What I was asking is, what are some techniques to practice, and when college throws subjects around at high speed to cover a ton of shit in a short amount of time, how do you guys work with that?
Also, if there are more books like Lang's, I would surely appreciate it!
>>8165584
>What I was asking is, what are some techniques to practice,
1. Find an area of mathematics you would like to learn more about.
2. Solve problems or prove theorems.
3. Repeat.
is mathematics just a branch of language?
>>8165457
Yeah sure whatever

Is /sci/ the most powerful and strengthy board on 4chan?
>>8165457
It's just an analogy
I'm searching for the expansion, e.g. to second order in [math] t [/math], of
[math] \prod_{n=1}^N \dfrac {1} {1-p_i(t)} [/math]
in closed form.
Any idea?
Something else: I'm currently doing statistics, working for a company which has some empirical curve (deaths in traffic) influenced by some measures (e.g. speed limit introduction in 1980, say) and I'm supposed to find out what would have likely happened if those measures weren't introduced.
Anybody know of this field, any /lit/ or ideas on what I can do there? I've...

what is p_i(t) ?? Or what can you tell us about it?
>>8165451
Is the repeated multiplication meant to be over the variable i or n? And what is pi(t)?
Redpill me on light.
What I know:
>a photon that travels like a wave, where the wavelength determines whether it penetrates different matter.
> e=mcc demonstrates the relationship between energy and light
> light is given off during exothermic reactions
> light is given off in LEDs when electrons gain velocity (higher shell) and then collapse into a more stable orbit
So redpill me on light. Give me all you've got.
Also, why does light travel in sine waves? Is the speed of light average displacement or the tangent vector? What can I read/what lectures can I look at to learn more about light?
What is the relationship between light and magnetic fields?

You don't deserve shit.
Your home planet moves at .75c relative to the center of the galaxy, you build a spaceship that can decelerate to stationary relative to the galaxy and then accelerate again to .75c. You take off and accelerate in the opposite direction of your planet's movement.
How fast does someone observing you from your home planet perceive you to be moving? according to Einstein's theory about .625c
however...
How much do you appear to have accelerated from the perspective of someone stationary relative to the galaxy?
How fast do you perceive yourself to be moving...

Problem. By "opposite direction", do we mean rotational or linear in respect to the center of the galaxy?
>>8165453
assume the galaxy is so big that the curve is negligible

Let's make a list of things necessary for the ultimate intellectual facade. In other words, the list of things that portray intelligence to proles and pseudo intellectuals but are not indicative of any intelligence at all. Someone who has all of these things could have an IQ of 50. Let's try not to overlap things so that it could feasibly all be done by one person.

Damn my nigger, your list is on point. Allow me to add some:

Fight me IRL. You're right about the rest, though.
>>8165236
This so much.
One of the most apparent indicators of stupidity is the phrase "I like reading". All it tells me is that you do so little reading in your daily life that you actually consider it a special activity when you take a break from your TV/pleb job to "read" some shitty fiction.
my eyesight is turning bad, why shouldn't I just push it for a few more years and then get laser surgery?
does the eyesight fade faster after surgery?
any experiences?
bump for interest
>>8165139
From what I heard, it shouldn't fade and if it does, it does within half a year and it should be covered by the people who did your operation.
>>8165139
This may be wrong, but according to a source that I cannot provide on account of the length of time that has passed since I read it, replacing the lens of the eye detaches the surrounding muscle and the eye loses its ability to focus on its own. Again, I read this somewhere I think, but it could be wrong.

How long would a helicopter have to hover in the air for before the earth starts moving beneath it?

That would be impossible.

Not baiting. If you're riding a skateboard and someone picks you up off that skateboard, the skateboard would keep going but you would stop.
Same principle.

I'm working on a roleplay character that uses a suit of armor not quite as big as pic related. The armor is 7 ft and weighs in at 800lb The character inside is another 200lb.
I'm having trouble with coming up with how much fuel (or what type of fuel) it will need to launch itself 450 ft vertically.
Help would be appreciated. I'm not very good a science.
>>8164749
7 ft? That's like 1 cm tall at best.
>>8164750

Is there anything mushrooms can't do?

Food, immune system bolster, medicine, beer, building material, and now leather.

mushrooms are the best
they would man's best friend if we could have plant friends.

Is this the only way to deduce that? I mean I know its fairly obvious but is there any sort of way to evaluate one one side to n = . . .
