In this post, we will see the book *This Amazingly Symmetrical World* by *Lev Tarasov*.

As we had written in the earlier post with Tarasov’s Calculus, which was remade electronically using LaTeX typesetting engine, this is another of his books which have been recreated with LaTeX.

The amount of efforts put in creating this book has been amply rewarded as the result has been aesthetically very pleasing for me. And in the process, I have learned a lot more about LaTeX and its packages. Hope this small effort is found useful by all. In case you find any typos please comment on the post.

Some snapshots from the remade book:

README.md

The project has the LaTeX source files for the book This Amazingly Symmetrical

World by Lev Tarasov. We have used the scans of the book for images and have

not recreated any of the images.Though I would have liked to create all the pages, especially the cover and the

art till the title page using TiKZ, for now, I have created pdfs for those pages

in Inkscape. Purists may not like it, but at least in this version, that is how things are. Also the tables are not made using LaTeX, but are simple scans. Perhaps in a later version of the book, we will have these two issues sorted.The original typesetting of the book lets itself to be very well typeset with one of Edward Tufte’s book style implemented in LaTeX.

If there are any errors while typesetting, for example, references, or typos

please report them so that they can be addressed.As usual, you will need all the package files to compile the book correctly.
