The Theoretical Minimum lecture series on theoretical physics by Leonard Susskind. Covers the basics in a very approachable way. I wish this had been available when I studied physics.

When I was in school "scientific method" wasn’t teached as a separate topic, but more like the result of "osmosis": you are given many examples of how science works and you somehow learn by this the process of science it

An (maybe) interesting fact is, that in Germany the notion „scientific method“, to my knowledge, is largely unknown. For example, there is no link in the english wikipedia entry you have given to the german wikipedia. When I studied physics

There is a free PDF on the nature site, but the paper is also available on arxiv ( https://arxiv.org/abs/1407.4437 ), the first version on the arxiv dates back to 2014. It's strange, but I find the arxiv version muc

Can you provide a link to the real paper that started the discussion? I looked through the references in the linked arxiv paper but could not find it.

I do not know "Mathematics: From the birth of numbers" but judging from the Amazon quick view it seems to cover a lot of ground (BTW: one thing I missed in my list are the basics of differential equations). Over 1000 pages is quit

This is discussed by Feynman as “physiological” work. See: http://www.feynmanlectures.caltech.edu/I_14.html#Ch14-S1

Math is wide and deep. You won’t need to cover every topic in math to get going with physics. If you really are interested in physics there are many things in math, which are, well, less important (for doing basic physics). For example LCM,

I just noticed in the article the passage from "The Dead Mountaineer’s Inn" ("Haven’t you ever noticed how much more interesting the unknown is than the known?") which is missing in the german translation from "edit

Yes, obviously the examples given in the link are bad style of comments. But sometimes you need to explain the reasons behind the (Haskell) equations, just like one would do in a Math paper. So there's a use case for the literate Haske

No, the energy gained will be equal or (most likely) less than the energy used. This is because we have conservation of energy, so a process like energy (the original photons) -> matter (electron/positron) -> energy can not pro

Mass is not a conserved quantity. Energy for example is a conserved quantity. So like in a nuclear fission reaction we loose mass but this lost mass is then converted into energy. I have not read the article in detail, but I suppose they wa

IANAL, so all this is layman wisdom: Yes, there are some checks in Germany. First of all this law has to pass the "Bundesrat", the representation of the 16 "Bundesländer" (states of Germany). If this council passes the law one still has the

Concerning software abstraction layers: What do you think of OpenCL? It's advertised as a way to utilise the combined computing power of multi-cores and GPUs. I am not at all an expert on this but it seems just too good to be true.

I was watching a video by Elizabeth Warren of Harvard Law School on the topic the other day. The gist of it is (I think) basically that housing and healthcare are taking up most of the money of the middle class. In the 1970-ties a single ea

I think they were referring to "Core Animation", a Cocoa framework for building smooth transitions in the GUI. This was AFAIK a by-product of the iPhone development. But development for Leopard is also nicer because you can now use Objectiv
