Introduction

I use this calendar for my own purposes finding information online.
I will add links to good sources for every note in the calendar.

11111912c!https://www.famousscientists.org/ is and Wikipedia are two of the sources I use. WIkipedia gives me good references for further studies.
It would have been good if www.famousscientists.org/ would have done that too.

N.B.
As I develope this page, it contains data about famous mathematicians/math and physicians/physics. I plan to divide this table in a math table and a physics table when I am ready with it.

I will add these scientists:

• Pascal (variable air pressure)
• Paul Dirac (matter/antimatter)
