Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

no. you have a 50/50 chance either way. if you switch you will only feel bad for not going with your gut instinct

Hey /sci/, brainlet here.
In physics we know that acceleration is the change in velocity over time. Yet I've see some weird formulas for finding acceleration such as pic related.
Is there any intuitive way to conceptualize why acceleration is equal to the change in velocity over twice the distance? Why does this work when the denominator is time AND when it is 2(d)? Why are we multiplying d by 2 in the first place?

Whoops. Meant d^2 not 2d.
But here is 2delta(d) in the denominator.
How is it that we can solve for the same variable (acceleration) using different denominators in (what would have been) the same equation?

>>8591377
That's... totally wrong. Units don't work.

I want to go to college for the physical sciences, but after a day of all honors classes (I'm a sophomore in high school) I don't even give a fuck. Should I spend less time playing video games and beating off to find out what field I actually want to get into?

You have to be 18+ to post here.
(Sign up for as many AP courses as you can for your junior and senior year, and take advanced math courses at your local community college your senior year. Try to discover and nurture an interest in a subject before going to college, and you will find yourself in a better position than 90% of those admitted. Video games, while fun, can be an enormous waste of time if you get carried away.)

This is not new and people already know this. It is certainly an offense to biologists to think that they are unaware how a variety takes place under same conditions. And they are not wasting their time by looking for phenotype function.

As many as one billion people worldwide are fed by fish. The collapse of marine food-webs, locally or wholesale, would have far reaching economic ramifications.

Well judging by his nomination, the public education system will get significantly worse while private for cost religious education systems will improve marginally.
Ultimately the middle class will be hurt the most as they wont be able to afford the schools which will benefit from his policies.
>>
It will be made great again, obviously.

Its interesting to me that when Donald was listing all the things that he will make America best at in the world, education was not one of them. But its not like Hilary would be any better. The Davos Men want humanity as retarded possible.

Don't date poor and stupid people regardless of how physically attractive they are.
Had to learn that lesson the hard way.
Guys my first year chem teacher said, and I quote almost verbatim: "glutamine has an Apolar group because N is present: since it's engaged in delocalization with carbonilic group it is not basic therefore it can create an hydrophobic site to accomodate a methyl residue."
What?
I mean I get why delocalization makes the amide non-basic but if anything it should impart an higher polar characteristic. Who's the retard here?

It's been years since my chem studies but I started thinking what interactions the side chain could have with water: it cannot be protonated, deprotonated and it cannot form hydrogen bonds. Therefore, it must be hydrophobic.
>>
>>8590273
What about this?
"The side chain contains an amide group, constituting a carbonyl (CO) and amine portion (NH 2 ). This amide group can hydrogen bond
via two lone pairs on the carbonyl oxygen, and one on the amine nitrogen, as well as two hydrogen atoms on the amine section.", and "Indeed, studies have suggested
that the stability of collapsed, globular polyQ chains results from an extensive hydrogen-bonding network between glutamine molecules, where glutamine−glutamine hydrogen bond interactions outweigh interactions with the surrounding solvent environment."
