Tracy;

That is the one - "Galloping Gertie"! It fell on November 7, 1940. Can you believe something happened before I was born? :)

>>>>When I was a child my grandfather gave me an encyclopedia printed in 1888. My grandfather was born 1890. The book was given to him by his parents and has the family names inside. As I recall the book describes the 9 planets in detail. But you say Pluto was not discovered until 1930? Why 9 planets? The book describes the planet Vulcan, which was thought to be between Mercury and the Sun but “fell into the Sun”.
>>>
>>>And today, astronomers are questioning whether Pluto should be labeled a planet: "If it were discovered nowadays, nobody would call it a planet". It is far smaller than the other planets. And the fact that it has a moon doesn't count either: other cases of double asteroids are known.

>>>>One week after graduating from engineering college all electronic and physics terms that were from the United States were changed to European terms. I was already “obsolete” and only 7 days after graduation! No more “cycles per second”. Now it is “Hertz per second”. "That Hertz”!
>>>
>>>As Dragan says, the unit is simply "Hertz". The "... per second" part is implied.

>>My Calculus instructor did the structural analysis on the Transamerica building in San Francisco. He is a licensed engineer in the state of California. During his first meeting he told us, “I do not care if you are off by a million as long as you show your work and your steps to solve the problem are correct”. I began to cry with laughter. He asked, “Mr. Whiteley, what is wrong”? I replied, “There was a famous suspension bridge in the State of Washington much like our Golden Gate Bridge, which would vibrate in the wind. One day the bridge collapsed sending cars into the water below. They informed the design engineer moments later. His response was”, ‘I guess I misplaced the decimal point’!

>>If the Transamerica building collapses during an earthquake I will remember my teachers words.

>>I also use terms like, “Miles per gallon”.
