The light turned yellow, just...

The light turned yellow, just in front of him. He did the right thing,stopping at the crosswalk, even though he could have beaten the red light by accelerating through the intersection.
The tailgating woman was furious and honked her horn, screaming in frustration, as she missed her chance to get through the intersection, dropping her cell phone and makeup.
As she was still in mid-rant, she heard a tap on her window and looked up into the face of a very serious police officer. The officer ordered her to exit her car with her hands up.
He took her to the police station where she was searched, fingerprinted, photographed, and placed in a holding cell.
After a couple of hours, a policeman approached the cell and opened the door. She was escorted back to the booking desk where the arresting officer was waiting with her personal effects.
He said, ''I'm very sorry for this mistake. You see, I pulled up behind your car while you were blowing your horn, flipping off the guy in front of you and cussing a blue streak at him. I noticed the 'What Would Jesus Do' bumper sticker, the 'Choose Life' license plate holder, the 'Follow Me to Sunday-School' bumper sticker, and the chrome-plated Christian fish emblem on the trunk, so naturally....I assumed you had stolen the car.''

Dayton Clarence Miller

Born 13 Mar 1866; died 22 Feb 1941 at age 74. American physicist. Author of The Science of Musical Sounds (1916). Miller's collection of nearly 1,650 flutes and other instruments, and other materials mostly related to the flute, is now at the Library of Congress. To provide a mechanical means of recording sound waves photographically, he invented the phonodeik (1908). He became expert in architectural ecoustics. During WW I, he was consulted concerning using his photodeik to help locate enemy guns. Miller spent considerable research effort on repeating the Michelson and Morley experiment, proposed by Maxwell, to detect a stationary aether. He spent some time working with Morley (1902-4), then more time at Mt. Wilson, recording results favoring the presence of the aether.
