Play hide and go seek

Einstein, Newton and Pascal are playing hide and go seek.

It's Einstein's turn to count so he covers his eyes and starts counting to ten.

Pascal runs off and hides.

Newton draws a one metre by one metre square on the ground in front of Einstein and stands in the middle of it.

Einstein reaches ten and uncovers his eyes.

He sees Newton immediately and exclaims, "Newton! I found you! You're it!"

Newton smiles and says, "you didn't find me, you found a Newton over a square metre. You found Pascal!"

Charles Augustus Young

Died 3 Jan 1908 at age 73 (born 15 Dec 1834).American astronomer who made the first observations of the flash spectrum of the Sun, proved the gaseous nature of the sun's corona and discovered the reversing layer of the solar atmosphere. He was a pioneer in the study of the spectrum of the sun and experimented in photographing solar prominences in full sunlight. On 22 Dec 1870, at the eclipse in Spain, he saw the lines of the solar spectrum all become bright for perhaps a second and a half (the "flash spectrum") and announced the "reversing layer." By exploring from the high altitude of Sherman, Wy. (1872), he more than doubled the number of bright lines he had observed in the chromosphere, By a comparison of observations, he concluded that magnetic conditions on the earth respond to solar disturbances.
