This is my homage to Mathologer’s wonderful video. The following is multiplication (2x to 100 x) modulo 200 represented on circle:

This is a wonderful book in content, scope and writing style. It is the newest entry of the list of must read books like: “The Mismeasure of Man” (Stephen Jay Gould), “Thinking Fast and Slow” (Daniel Kahneman).

The author guides us through a historical journey of the gene and the genome. The writing style is vivid, clear and grounded by real examples, some deeply personal insights as the title expresses.

The book served both as an education, an insight into how and who does science and an appeal to deeper understanding of genetics  important implications for the future.

This animated gif was made using POV-Ray. The Menger sponge code was found on a Google search (I cannot find at present) and the animation made in standard manner.

I reached 40000 on Mathematica Stackexchange this week. This has been a difficult year and I hope that soon I will start again to traverse this interesting world with my eyes and mind open.

To Be Or Not To Be

Physician and medical student suicide is an increasingly recognized area for concern. The film “Do No Harm” will likely be a powerful window into this problem. Milner et al report on the prevalence of doctor and other health professional suicide in Australia. This post is a Bayesian analysis of the data presented in the paper.


Trade-offs

The brachistochrone problem is classical example used to illustrate the use of calculus of variations. In some ways it illustrates the trade-off between shortest distance (straight line) and greatest speed for a time minimization problem. The solution curve is a cycloid. In addition to the time minimization, no matter where start on the curve you will reach the end point in the same time.
