"I did not think; I investigated."

German physicist Wilhelm Conrad Röntgen died in 1923.

On 8 November 1895, he produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901. The non-SI unit of radiation exposure, the roentgen (R), is also named after him.

Dutch-Swiss mathematician and physicist Daniel Bernoulli was born in 1700.

He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics. His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy.
