The letter I sent on March 17, 2024 to the US Senate Majority Leader Chuck Schumer as a comment to his Senate speech about the prospects of peace in Palestine.

The letter I sent on March 7, 2022 to the office of the Rector of the Moscow State University, mathematician V. A. Sadovnichiy, in connection with his endorsement of Russia's invasion of Ukraine

* Did you know: In one's
afterlife, one is condemned to finding counter-examples to all false
statements made in life? Hence the advice: Start early! *

From W. H. Aumer:

*
Two millenniums back / Euclid founded the science of Data.
Two Wikipedia lines / are all it merits to date. *

A duck with ducklings

I have finally produced it as an e-book available at Sumizdat

together with about 100 sample pages.

It is available at Sumizdat . Here are sample lectures ,

which include the entire material on groups.

Here are several sample chapters in PDF format.

Now complete with exercises and some solutions,

this book is not a work in progress anymore,

and is available in its entirety as an e-book.

A book for grownups about children's mathematics

Aharoni played a major role in a successful fight against "fuzzy math" in his country, and in the implementation of a competent, no-frills curriculum (based on Primary Math from Singapore).

In this book, he shares with the reader -- a parent, or a teacher -- the insights he gained concerning elementary mathematics and mathematical education.

Available from Sumizdat , Amazon.com and SingaporeMath.com.
