geologists could also tell you where the best rocks are.

FTFY

If we put it like that, every other energy source on earth begins that way and adds at least one conversion step.

… except for fusion of course.

Solar cells, technically.

boiling water systems have a thermal efficiency of ~40% Solar cells are closer to 45% efficient

This is just plain false.

There is no theoretical size limit to unobserved quantum systems, although it is practically hard to achieve large ones.

the largest ones we’ve managed are over 100 atoms. https://www.livescience.com/19268-quantum-double-slit-experiment-largest-molecules.html

Yeah its about quantum systems interacting, not sentient beings watching.

still pretty mystical though in my book!

That is not infinity, its undefined.

This only works if you use a one sided limit.

omniseasonal is still seasonal ;D

the description fits my uneducated stereotype of the automotive industry.

Swede here. I’ve only heard about things like this in american movies.

This number goes for any substance

There are 20 billion calories in a gram of diet coke too

This is the solution to E=mc^2

If we are talking dietary calories uranium is close to 0

This is not accurate, only 93% has died so far!

hurr durr maybe it’s a vector in ℝ

What they actually see:

convolution
cross product
dot product
multiplication

US law is an interesting response to an ethics question

The problem with only counting calories for health has never been more aptly highlighted!

as does the same amount of any other substance, including for example yoghurt.

That number is just the E in E=mc²

If we are actually talking dietary calories, the number you see on foodstuff packaging, plutonium has 0.

when comparing to kg I will assume the mass unit, since comparing a mass value to a force has no meaning.

when compared to a value in Kg, the only logical interpretation is the mass pound. If it were lbf, the si unit conversion would be Newtons.

Having the same name for two different, but easily mixed up units is really annoying haha

The bar is defined to be close to the atmospheric pressure of one random planet called earth, why choose that as your pressure unit?
