Elon Musk has just unveiled the Hyperloop, well with the air in the tunnels included. Cantor spaceMandelbrot space. To see that string topology is dnitry part of the mathematical subcommunity of the broader string theory community, see also this string topology workshop in Stony Brook that defines the subject pretty clearly.


The money must be used for higher education. Wolfram Alpha answers your query. His victory shouldn’t be unexpected especially because he looks like Brian Greene a bit, doesn’t he? topolgy

See the history of this page for a list of all contributions to it. The study of string topology was initated by Moira Chas and Dennis Sullivan. Michael Nielsen, an achieved quantum information researcher, just wrote a fun essay What does the quantum state mean?

Pageviews since July Mathematics or mathematical physics don’t have to be a financial disaster as long as you stay at the high school. Ralph CohenJohn R.

Now, your humble correspondent doesn’t like to view these things as a rigorous mathematician and he doesn’t understand most of these things but he can still recognize that they often study the same structures with a different focus and motivation, with higher standards of rigor, with smaller or no attention to the physical relevance, and with a higher degree gopology generality than what is useful for physics.

Sabine Hossenfelder became notorious for her obnoxiously demagogic and scientifically ludicrous diatribes against theoretical physics — she Check Mathematica on TRF.

When terms, phrases, slogans don’t repay the time needed to learn them. The structures studied in the string topology of a smooth manifold X X may be understood as being essentially the data of a 2-dimensional topological field theory sigma model with target space X Xor rather its linearization to an HQFT with due care on some technical subtleties.
