Instead of celebrating the birthday of the famous crazy Jew Jesus, lets celebrate the birthday of the greatest mind of all time: Isaac Newton
To me Isaac Newton is the greatest mind of all time. In addition to famously laying foundation for classical mechanics, realizing the mathematics available to him at that time was not sufficient for his work in physics, he independently developed Calculus and Numerical methods.
He's all over physics: optics, heat, gravity, where ever you look you see contributions from Newton. What he achieved during his lifetime quite unbelievable and extraordinary. Happy birthday Sir Newton.
