Sibling lessons

Charlie was playing with his little brother Mickey when the little boy asked whether he could fly like Superman.

"Sure you can, Mickey," Charlie said, "Just flap your arms really *really* hard."

So Mickey climbed up on the windowsill, started flapping like mad, jumped, then smashed into the ground two stories below.

Horrified, their mother came screaming into the room and said, "What the heck happened?!?"

Charlie said, "I was just teaching Mickey not to believe everything someone tells him."

John Stanley Plaskett

Born 17 Nov 1865; died 17 Oct 1941 at age 75.Canadian astronomer known for his expert design of instruments and his extensive spectroscopic observations. He designed an exceptionally efficient spectrograph for the 15-inch refractor and measured radial velocities and found orbits of spectroscopic binary stars. He designed and supervised construction of the 72-inch reflector built for the new Dominion Astrophysical Observatory in Victoria and was appointed its first director in 1917. There he extended the work on radial velocities and spectroscopic binaries and studied spectra of O and B-type stars. In the 1930s he published the first detailed analysis of the rotation of the Milky Way, demonstrating that the sun is two-thirds out from the centre of our galaxy about which it revolves once in 220 million years.
