There are smart people in the UK, Europe, etc who get top grades in their finals and yet decide to pursue Physics, Math, etc instead of Medicine, Law, etc for their undergraduate degrees. Some aspire to do research in the future.
Yes, I understand that being a doctor or lawyer is stressful, but why don't these smart people go for "easy" jobs instead? Being a physiotherapist, nutritionist or actuary is not that stressful. Working for the government is nice as it's difficult to be fired from your job. This is certainly the case compared to something such as a researcher where no results = no funding = no income.
Really, all jobs are boring in their own ways. Even if they are interesting at the start, they become dull over time. Why not just pick something which leads to a stable income and learn to love that job?

This one is different from the one last time.
Simply put, because they love to learn and discover, and it's thrilling to go into uncharted territory.
And we should all be happy that they want to do this. It's because of the curious minds like those that we get new technologies, algorithms, maths, which shapes the modern world.
>people frequently get diseases from animals
>animals rarely if ever get diseases from us
what is this shit
le shitposting vegan face
>>7763011
are you giving every animal an autopsy to know this?
didn't think so
now delete your worthless thread
>>7763011
Animals rarely consume humans. Humans rarely bite animals and run away. Ontop of that we dont really document where animals get their diseases
Guys I'm confused with this, different answers all over the place. The 'correct' answer does not make much sense either.
>A speeding truck locks it brakes and it skids to a stop. If the truck's total mass were doubled,what would happen to its skidding distance? Why?
If you work it out mathematically it would be 1/2 the original stopping distance.
But the 'official answer' is they are the same? Are they just accounting for the brakes? Don't brakes rely on friction, The answer should be 1/2 of the before mentioned skidding distance. Help /sci?
>>7762981
apply newtons second law. that should be all you need to figure it out from here.
>>7762981
the distance would double (roughly) because the more mass means more inertia.
Using basic mechanics you can get mass to divide out on both sides of the equation. This means that the mass doesn't matter, so the time will be the same.
Basically
Ffriction = Fnormal * mu
Fnormal = weight
substitute known quantities

Hey sci what the strongest nonnuclear explosive I'm curious
Like whatever amount of tons of TNT you can think of +1

TNT I guess
"The challenge is not to act automatically. It's to find an action that is not automatic. From painting, to breathing, to talking, to fucking. To falling in love..."
What do you guys think he meant by that?
>>7762950
It's pretty self explanatory isn't it? If there was an "automatic" algorithm for the behaviors we consider human intelligence, emotions, and creativity, AI would already exist.
>>7762950
The writer?
He was insulting the audience's intelligence. It's very subtle, no?
>>7762950
Complete nonsense, because all of those are automatic.
I don't quite understand how vaccines work, how is it that they inject you with dead virus cells? Virus cells are neither living nor dead so how can they inject you with something that cannot die. Are viruses like the undead?
Also why do vaccines cause pain in the injection site and sleepingess?
>>7762883
I've always wondered does drinking alcohol after a vaccine mess up the vaccine and like kill the things in it?
>>7762883
Viruses have two parts:
1) An outer shell that delivers the payload. This is the part the immune system detects.
2) A DNA payload that instructs the infected cell to make more viruses
Non-working or missing payload = can't replicate = virus is dead.
Living and dead are arbitrary terms when it comes down to it as seen by things considered borderline like viruses. You could say they are inactive if you want but it's just semantics. Though as far as I know most vaccines do not contain inactive viruses so much as weakened viruses that can not reproduce as easily or cause nearly as much damage as a normal virus. Either way, the body easily eliminates the weakened viruses after which the body can then through the use of memory cells, which were formed from B and T cells used to fight the virus, can later be used by the body to quickly detect and eliminate the virus if it reappears.
Is it normal to have this abnormally big (especially the left one) frontal sinuses?
Is it normal to have painful frontal headaches day in day out?
Is it normal to often have continuous rhinorrhea and sneezing lasting up to 10 hours?
Is it normal to have horrendous stabbing headaches that make me discharge mucus with blood from my nasal cavities for a whole week after being on a plane?
Is all that normal? Because that's all I'm getting from the doctors. Everything seems to be normal.
What do you want them to do, empty-head? For them to fill you with their thick cum?

is this nigger serious?
Can someone else how the physics behind the water cyclone in this pic. what causes that tornado to form and why is the water being sucked inwards in the hole at the bottom
>>7762756
pressure
Can someone please explain how using this mixer causes the water to spin in a way where >>7762762
Care to elaborate?
eletrcomagnetic force produced by the crust of the Earth interacts with the ions in undistilled water and creates potential energy that is released when an exit is created at the bottom. That is why if you fill your bath with distilled water and let it drain, it won't create a cyclone.
Hey /sci/, Say I want to start breeding cockroaches for size. How soon will there be noticeable results?
you could expect noticeable results in a dozen generations, which would be three or four years
>>7762688
Insects cannot grow larger than 10 cm diameter. Because Malpighi.

Let's try having a nice biology thread:
Post your biology-related thoughts, questions, problems and have people discuss them with you.
No college advice.
Pic unrelated
>>7762654
Umm biology yeah the thing is that we are intelligently created by god.
Biology is spelled b i o l o g y
>>7762654
What's the best way to learn biology/physiology for someone who is NOT math phobic but doesn't give one shit for typical stamp collecting in biology like memorizing 10000 different enzymes in the body?
Can someone tell me if these odds are worth playing? I have a friend who says, theoretically, I can always do this with him.
Pay him 25 cents to play.
Then I get to roll 3 dice.
If I get a 3, he gives me $10. There is a 1/216 or .5% chance of getting this.
If I get a 7, I get my quarter back. There is a 15/216 or 7% chance of getting this.
I get a 13, I get $2. There is a 9.7% chance of getting this.
I get an 18, I get $5. There is 1/216 or a .5% chance of getting this.
Wouldn't the dealer end up losing with these odds? Especially with the 13, at 9.7 paying $2. Also, 25 cents for a .5% chance to win $10 doesn't seem like good house odds to me, but I don't know about this stuff. I suspect he doesn't either.
I'm a girl btw ;)
>>7762678
Simple probability,
[math] expected winnings ($) = \Sigma (probabilities \times winnings) - $0.25[/math]
So your expected winnings is
[math] $10 \times \frac {1}{216} + $0.25 \times \frac {15}{216} + $2 \times \frac {21}{216} + $5 \times \frac{1}{216} - $0.25 [/math]
or $0.03125.
So technically you win 3 cents per round.
What does /sci/ think about brain training?
>>7762628
Never been interested, it just seems like silly mini games to me.
I used it for a period of time consistently. Hell, I've even bought the subscription for it and I also got 2 other similar apps and did "games" on them as well. I noticed no tangible benefits after weeks of using them. Though my scores did increase over time.

The conjoined twins were born in Tondo of Miya in Ganjuwa Local Government Area of Bauchi State, Nigeria over the weekend. According to Aminu Bombiyo who shared the photos, the twins were delivered at home before being brought to ATBU Teaching Hospital Bauchi. Their mother, a poor Fulani nomad named Adama Sani is seeking for assistance. See more photos...

They should probably just kill it desu.
>>7762552
that'll happen by itself
>>7762536
ayy lmao
but seriously, i hope that in 100 years these kind of occurrences are a thing of the past.
>browse /sci/ everyday
>understand nothing about maths, physics, chemistry or engineering
anyone with me? I just wanna smoke weed and think about black holes and shit

how the fuck do you decide what you will study for the next 4-5 years? this is insane. what if you lose interest?
i'm interested in superconductors, CPU architecture, heat exchangers, propulsion systems, chemical explosives, protein synthesis, nonlinear PDEs, energy storage, machine learning/cryptography, lithography/crystallography, electroactive polymers, josephson junctions, multijunction solar arrays, all both in theory and in application. am i fucked? some anon here said do material science, electrical engineering, or physics. pic related.
>>7762445
if you can't even decide what to study at uni then what hope is there for you?
also why are you asking on /sci/ rather than /adv/ and why did you choose a meme picture that makes me hate you?
How do you get to undergrad level and not know what topics you're interested in?
>>7762454
Get help. Seriously
