We never sit here under the weight of all this air, the 5 x 10^18 kg of atmosphere that sits above everyone on Earth, and say “Gosh, that sure is heavy!”
You don’t realize just how powerful that 1 bar (~100 kPa) of pressure is until a train car is filled with steam, allowed to cool, and then implodes ohmygod did that just happen?

Gifs from Chris Hadfield’s Space Oddity [X]
Respect and love to this man. One of the finest commanders the ISS has seen and which we’ve all shared in his journey. Thank you, Sir Chris Hadfield, for your amazing photography and continual public outreach for the scientific community. Humanity (and Canada) salute you.

Can someone from the sciencey side of tumblr please explain this ?
This is called shape memory. It’s made from an alloy of titanium and nickel (I believe it’s called nitinol). It has the ability to “remember” the shape it’s taken.
When cold you can bend it whatever which way, but once you heat it (or in this case put it in what I presume is hot water) it will take the original shape.
WHAT!!?!?!?!?

Electromagnetic Spectrum - Range Visible by Humans
The spectrum of sunlight has approximately the spectrum of a black-body radiating at about 6,000 K,- Electromagnetic waves that are low frequency
have low energy and a long wavelength - Electromagnetic waves that are high frequency
have high energy and a short wavelength.
All electromagnetic waves travel at the same speed - the “speed of light” (c = 300,000 km/sec or 186,000 miles/sec).

like honestly.
start with a function that can be expressed as the product of two functions, u and v.
uv
take the derivative of that function
(uv)’=u’v+uv’
so
u’v=(uv)’-uv’
Integrate that shit
∫ u’v = ∫(uv)’ - ∫uv’
and of course the ∫(uv)’ is just uv.
∫ u’v = uv - ∫uv’
WHAT
I appreciate this post. I appreciate integration by parts.

Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of kids. They outnumber kids. They vote. They wield resources. That’s why my public focus is primarily adults.
