Why are /sci/entific geniuses always left wing?

How did this snarky jew manage to build a literal cult around himself while rejecting the very idea at the same time?

What board has the highest percentage of people who actually know what they are talking about? (I know none of them are over 3% with 97% retards but which has the least retards)

Also because fuck jtranny annies and their bullshit bans. What is the solution to Rheimann

So we've had metallic foam for a long time, and its properties are more or less well understood. But, metallic wood is a relatively new discovery, taking the concept of cellular metal to the next logical step. Does anyone have proper resources or really anything regarding its properties, uses, etc? When stuff gets this small, expectations go out the window. I'd love to see about using it structurally, but the increased surface area makes it look like a nightmare for corrosion and general stickiness.

Sup /sci/ retard here.
I have a math problem that i don't understand but i need to understand.
english is not my third language so be patient with me please.
I have to learn few simple things about triangles but apparently i don't understand a thing.
>Pic rel
Let's say that i have an object that's 168 cm tall (a pole).
Let's say that my eye is at a 90 degree angle directly in the middle of pole (it has to be in the middle alyways).
That would give me a top triangle, simple.

Now let's say that 90 degree angle stays in place, lenght of top stays in place and 168 cm pole "leans foward" (middle triangle).

Now same thing but it leans backward.
Now my question is:
is there a way to calculate a size of object of known height (168cmfor example) that is leaning foward/backward (like michael jackson) assuming that 90 degree angle and one of how do i calculate angular size of leaning object, what do i need, how do i work with this ?

is there a way to calculate a percentage loss of vieved height per one angle ? this would help me the most it sounds simple

please don't askk me why i want to know this it's embarrasing
i also lack technical english word phrases so please be patient with me

What’s the difference?

Prove that:
a(1) < b(1)
a(2) < b(2)
a(3) < b(3)
I was reading a calculus textbook and the author says it is a simple matter to prove this using elementary geometry.
