Well I don't have a permanent job, I'm an adjunct, and not based in the US so maybe I experience a slightly different job market to your cohort. I was mainly focusing on the line "targeting those who could not complete STEM d

Similarly a lot of stuff that falls under the STEM umbrella is completely useless. I have spent months and years of my life working on difficult math problems a bunch of which will probably never have any real-world application.

Speaking as someone who went pretty heavily into STEM (I have a PhD in math and work as a mathematical physicist) I absolutely hate this view. I have not seen any evidence that on average STEM is harder in a meaningful sense than non-STEM

There are also some algorithms for trying to deal with symbolic integrals but they're pretty intense compared to what you have to do for derivatives (which are very easy).

by eigenket 5y ago
Any interest in adding more symbolic stuff? There often isn't really any reason to do derivatives numerically. While I was looking at the derivatives I noticed the word "quotinent" should be "quotient" in the readme

Also the US has five times the population of the UK, and 40 times the area.

I don't know what it really means for a proof to be invoked, and I also don't really like the idea of separating proofs into concrete and abstract proofs. Either it proves something or it doesn't.

That is neither a beach ball, nor a tree.

A more modern mathematician might say something like "God made the empty set, all else is the work of man".

I think you have a slightly stricter definition of "a proof" than me. I would consider a proof that all the numbers in (0,1) are positive to also be a proof that the number 0.5 is positive, as well as the number 1/e, and Cham

I genuinely don't understand what this means. How a beach ball a tree? What about the symmetry group of the beach ball?

I am somewhat familiar with the standard foundation of maths in set theory, and slightly less familiar with the program to ground maths in Category theory (although I do know a fair bit of category theory). Maybe I am biased but I do not fi

Almost all of modern mathematics is not about numbers, although a lot of the objects studied can eventually be related to numbers in some way.

Could you give an example of exactly what you think they're doing wrong? I've read a few of these papers and I've not seen any such issues.

You're missing something I think (or we're talking past each other) because I can write down probability distributions which explicitly break Bell's inequalities, whereas I can't write down probability distributions whic
677.
by eigenket 5y ago
Ah yeah, I went to skim the Pitowsky reference. I forgot that people call (what I was taught as) Bonferroni inequalities Boole's inequalities. I'm still not sure what probability distribution (or measure) you want to be defined in
678.
by eigenket 5y ago
If by Boole's inequality you mean the thing that I know as the union bound, then it is far from obvious to me that it is exactly the same as Bell's theorem. In fact they seem to me to be completely different. Boole's inequali

To clarify, have you actually seen any of these errors in the papers, or are you just hoping/believing/assuming they are there?

I am generally positive towards the mwi/Everetian approach, but it should be emphasised that we really don't have a satisfactory understanding of what "measurement" is in the Everetian approach, and in particular I don&#

What do you think is happening in the experiments in 2015 in Delft, Vienna and Boulder and Rosenfeld et al. from 2017 (or any other Bell test you like)?

I don't think many physicists really think of entanglement as a problem now. Its kinda weird, but its also completely consistent, doesn't lead to any wild paradoxes and turns out to be very useful in a variety of scenarios. I thin

So you can describe the set of possible joint probability distributions for the socks, and you can describe the set of possible probability distributions you can get out of quantum mechanics in a "Bell-type experiment". It turns o

I think this comment is coming from a very different place to my experience. Academic work is much less predictable than the sort of work you seem to be talking about. Like we're doing maths that no one in the world has done before, an

A lot of comments on anything about quantum information/computation/foundations are definitely nonsense. Thats the only field I'm really qualified to make such judgements about.

I (in the CEST time zone) am currently collaborating with a colleague who lives in Australia, because academics often don't get to choose where they end up. Its a fucking mess, most of the time its ok, we can meet in the early morning

The only role surface tension plays in the Feynman problem is to ensure that the cross section of the stream is a circle. The rest you can work out based on classical mechanics and the fact that the amount of water is conserved. You actuall

Yeah thats probably a more reasonable explanation than my theory. On the other hand its pretty common to say silos, speedos (both for swimwear and slang for a speedometer) and flamingos in British english and they have very similar endings.

Interestingly the company initially wanted people to call them "Froffles", but people apparently called them "eggos" due to the fact that they taste eggy. Then the company changed the name to "eggo" to reflect
