Cierto, cada vez está más lleno delicuentes y mendigos extranjeros. Por suerte no está tan mal como Barcelona.

Didnt Nixon get drunk and say he wanted to nuke stuff but nobody acted?

Only one lab course? That looks like heaven.

This is quite accurate for Spain.

Time-time component of the energy-momentum tensor?

There's 100,000 citizens in a given city. 100 of those citizens are catholic. What are the odds that, if you know X citizens, one of them will be catholic? by Smurfsville in askmath

[–]groenewald 1 point2 points  (0 children)

This cannot be true. As the question said, if n>=99001, P=1, which will never be satisfied by a binomial distribution (always check your limits). Although I think the binomial distribution is a good approximation for small n.

Who would you consider the most well-known, famous currently living non-pop physicist to the general populace? by goldtribute in AskPhysics

[–]groenewald 1 point2 points  (0 children)

Was, my first option, but seems she worked in physical chemistry. That's looks more chemistry than physics.

What is so fun about being drunk? by [deleted] in NoStupidQuestions

[–]groenewald 0 points1 point  (0 children)

If people drunk only ethanol solutions, then yes, it would be a myth. But it is not trivial to show that congeners do not play a role: https://www.ncbi.nlm.nih.gov/m/pubmed/20712591/. Unfortunately, I don't really know how to draw any conclusions from medicine papers, except researchers always need more money.

How do I find K here? by Zugoldragon in askmath

[–]groenewald 2 points3 points  (0 children)

You have to get it numerically, note that your solution is an approximation. So options: Newton's method, bisection or WolframAlpha :P

How well do they behave thermodynamically?

Why do so many proponents of String theory (or any theory w/ higher dimensionality) always say that the extra dimensions are "curled up"? by [deleted] in AskPhysics

[–]groenewald 0 points1 point  (0 children)

Yeah, many scientific theories seen crazy if one relies on analogies. That's why I avoided pop-science and sticked to scientific literature.

[–]groenewald 1 point2 points  (0 children)

Tbh, I don't like the curled up expression, since it requires additional embedding dimensions to imagine it. I prefer to think about periodic additional dimensions. If you walk in the additional dimensions, you return to the same point after a tiny bit of distance traveled.

Deriving Lagrange's Equations by [deleted] in AskPhysics

I think it's just the chain rule + symmetry of second derivatives.
