Just a note, the Planck lenght is not the smallest possible distance. The plank length is where quantum and graviational effects are of the same "size" and as such, both our theory for gravity and our theory for quantum physics ar

There is other live with almost 100% certainty in the universe. The number of galaxies, stars and planets across the whole universe is just too large for this not to be true. The thought that humans might be the only life in the universe to

No it's not. It's a state facilitated oligopoly situation, which is the ideal end state for any industry as part of capitalism short of a monopoly. Guaranteed high income for everybody involved and disruption essentially not possi

So I think one conceptual issue that makes this so hard to understand is that we tend to imagine a physical reality where light is a wave or a stream of particles. However, that is absolutely wrong. Both the wave and the particle concept ar

That's not really correct. A torus is a 2-dimensional manifold that can be embedded into 3-dimensional Riemannian space. The author of the article is correct talking about a three dimensional torus as it's defined as S^1 x S^1 x S

Germany splits students into different schools starting 5th grade and it's absolutely great.

Just a small comment about the speed of light. The way we now define the speed of light, measuring it doesn't really make sense anymore. The speed of light is now DEFINED as 299792458 m/s and the meter definition is based on the s

It's not related directly. However, the parent comment to mine talked about choosing the US because "Freedom of speech is of the highest priority for me". My comment was that I don't get this at all. I would value other

Coming from Europe, this obsession with "free speech" that Americans have is kind of weird to me. How is that more important to you than affordable education and healthcare and reasonable gun policies where every crazy person cann

Your comment reminds me of an old math professor of mine that told an anecdote about some famous mathematician that used to have a very promising student. However, after a while the student left and a colleague to the famous mathematician a

Hmm, this is stuff physicists learn in their first year undergrad classes for mathematical foundations. Seems to me it's the very definition of beginner.

For a long time I loved reading comments to news stories or other discussions on reddit, for example. But I have found that most comments are actually at the very least misinformed, often wrong and clearly not very educated and I have start

In Germany they have a three track school system which is great: - The first track is the high school degree that includes 13 years of school and afterwards allows people to attend university. Generally the students with the best grades att

There is a slight mistake in the article. The standard model does not describe the neutrinos. In the standard model neutrinos are massless particles, but in reality they are not.

I mean, replication failures are a result of bad science, bad analysis and a poor understanding of statistics in many cases. It's not so much a crisis in the state of human knowledge but the state of the education of the scientists in

The number of partners does in no way tell you much about the amount of sex people have. A person could have a single partner their whole life but bang every day. Compare that to a person who hooks up with a new person once every two weeks.

Apple watch can save a few MP3s. My really old one can save at least a couple of albums and I never carry my phone with me. The watch connects to bluetooth headphones.

This seems like a random collection of equations from a 1st/2nd year undergrad physics class + Black Scholes.

I think one of the major reasons is that physicists actually understand math and statistics and from the first year of university learn how to design, run and analyze experiments properly and quantify uncertainty. This is a big difference t

Sounds sensible to me. Similar laws exist for negligence with physical products that cause damages.

Also crazy large doctor salaries. The US pays way more to doctors than for example many European countries.

If you are a physicist, Abraham Pais' "Subtle is the Lord" about Einstein's accomplishments in physics is an absolutely unique and amazing book. However, I didn't ask if you are a physicist for no reason. It talks m

There is a very clear definition of convexity, as can be seen here [1] on Wikipedia. Nothing to discuss about with regards to definition. [1] https://en.wikipedia.org/wiki/Convex_set

I think this is a ridiculous opinion to have. I actually think unvaccinated people were treated way to well in Germany. They are a very loud minority in society and have managed to really hamper the progress against covid. Compare this to C

The majority are unvaccinated people. It's really their own god damn fault for not getting vaccinated. At the most there should be a lockdown for unvaccinated people.
