can you give an example for what yluean be equation incthose dimensions?

{(x,y,z) | y=0 and z=0}

specifies a line in 3 dim

>>8626994
One slope minus the other?

Each point on the bottom line is .2491 units below the top line.

>>8626994

>>8627009
Sorry let me reword that.

Every point on the top line is 0.2491 units above an adjacent point on the bottom line.

average pupil size in elemetary students is up

Why?

Because most objects absorb most light waves and reflect most soundwaves.

Go to school?

To better understand physics, then you should shoot for a basic understanding of algebra and calculus.

/sci/ has already compiled everything you need to know to understand Physics auto-didactically.

>>8626533
well the navy is going to provide me with the schooling, i want to learn it on my own, iv started with "physics for dummies" right now, but it would be nice if i could have some other suggestions

>>8626536
i think i have an okay understanding of algebra perhaps calculus would be a good path to start as well though.

>>8626400
Culture? Perhaps.
Social structure is apparant in wolves, lions, ...
This is LEARNED behaviour (= knowledge)
Therefor, your hypothesis is destroyed.

Absolutely. Some high class Japanese monkeys season their potatoes in salt water before eating.

But still, you are right. That is a unique ability that very few species take part in.

That book is as close to pure shit as you can get. The experiment is very easy to understand.

Say you have to sailboats with both sails and engines, and there is a wind in a certain direction.
Now, you orient one sailboat to sail at about 45º from the other, both racing to reach the same distance from their starts. Because of the sails catching the wind, one will inevitably reach the finish line earlier than the other, since they sailed in 2 different directions with respect to the wind.
If there was no wind, then they would reach the finish line at the same time.

Now in the late 80s, scientists thought that there was a medium called aether, just like an atmosphere is the medium where wind exists. This was the medium where light waves were supposed to be carried.
Because the earth is moving very fast, that movement should create a wind in the aether. Therefore, if you replicate the sailboat experiment with two beams of light, or rather with one beam that is split and then recombined, if there was wind then one beam would reach the detector earlier.

Because both beams reached the detector at the same time, they proved there was no aether (because there was no wind) and that light could travel in a vacuum.

But seriously don't read that piece of shit book.

Michelson Morley was a dud, wrong premises, wrong apparatus, wrong conclusion.

As a whole hawking-show, it's no better then medieval divinator-monsters :

Asking a wheelchair-bound freak to explain profound meaning of universe, life and all.

Depends on physiology of person and rate of intake (constant, bursts over certain timeframes, ..)

But I don't know alot about that shit. Wiki says to float between 0.4-0.8 mM/L range.
So, you've got 0.01218 M Li2CO3, which is like 12,18 mM of that shit to spread out over 1.5 years. I'd say minimal to no effects, probably won't even feel any effects.

I'm a fit guy who exercises everyday

>>8626405
wait, is that 900mg per dosage or 900mg total to sprad out?
Because if we're talking 900mg total it's peanuts, but if it's 900 mg / dosage, I'd say spread that shit out over the entire week.
Also: why take Lithium?

It's to test you to see if you know how shit works regarding your field, sort of a way of weeding out the capable from the incompetent.

Get his/her e-mail. If he's not a dead beat, I bet he would like to help you out (as long as you are polite). Most people like to see their work bare fruit.

>Why do you think East Asians evolved differently than Europeans?

geographically isolated populations ALWAYS evolve differently from one another.

it's how evolution works.

>>8626060
Asians are so ugly damn.

>humans
>evolved differently
back to /pol

Because that are the things we already know. You wouldn't describe a bike like a two wheeled, leg powered, vehicle.

why don't they just use normal guns in star wars? the energy weapons are slow enough to be blocked by lightsabers.

obvious stuff like this kind of ruins most scifi for me.

And even then, Blasters are far more practical weapons than Lightsabers. Lucas even admitted he only added them because he likes swords.

It's constantly tilted in the same direction, as shown in your picture, hence the seasons. There's some drift over hundreds and thousands of years.

>falling for the STEM meme

for a bunch of cicrcle-jerking intellectuals like /sci/, I'd imagine they'd be smart enough to check wanted ads in their field before graduating to get an idea of the relevant knowledge needed.

Guess not, psueds.

You only have yourself to blame.
