Maths - Internal Language of Topoi - Bewl

Using JetBrains to run Bewl

I have tried to use JetBrains to run Bewl

I installed JetBrains as shown on this page.

I then tried running JetBrains as follow:

mjb@localhost:~> cd idea-IC-222.3345.118/bin
mjb@localhost:~/idea-IC-222.3345.118/bin> ./idea.sh

I then created a new project:

Here is the empty project.

I then clicked on: new -> project from existing sources

This brought up a dialog window and I selected sbt

In the second dialog box I selected openjdk-18

The Bewl files are now in Intellij IDEA:

Correspondence about this page

Book Shop - Further reading.

Where I can, I have put links to Amazon for books that are relevant to the subject, click on the appropriate country flag to get more details of the book or to buy it from them.

The Princeton Companion to Mathematics - This is a big book that attempts to give a wide overview of the whole of mathematics, inevitably there are many things missing, but it gives a good insight into the history, concepts, branches, theorems and wider perspective of mathematics. It is well written and, if you are interested in maths, this is the type of book where you can open a page at random and find something interesting to read. To some extent it can be used as a reference book, although it doesn't have tables of formula for trig functions and so on, but where it is most useful is when you want to read about various topics to find out which topics are interesting and relevant to you.
