The "cleaned up" displays at OSC reminded me of my last trip to the Museum of Science and Industry in Chicago, Ill. I was first there in 1949 and spent the entire day looking at the industrial exhibits, the Physics displays etc. The industrial exhibits showed patterns and castings for a four cylinder automobile engine, how twist drills were made and a multitude of other manufacturing displays. Physics displays were all interactive wherein you pressed a button and they operated so you could see how the laws of physics worked. There was a huge "Newton's Cradle" made of iron balls hanging in contact with each other, a 3 foot diameter horizontal wheel with an electric train track around the rim. Push the button and the train would start forward while pushing the track backwards, Newtons law of action and reaction. Lots of similar goodies to tickle the mind. A Foucault pendulum about 40 feet high swinging back and forth while knocking over a circle of wooden pegs as the earth rotated. Switch to a few years ago and most everything was graphics while all the solid exhibits were gone with the exception of the very real full size coal mine and the pendulum. The WWII Nazi U-boat was something new, but that was about it. I left a much sadder person since I remembered how it once was before it had been dumbed down and sanitized for the under performing school students (I suppose) to be able to comprehend via graphics. Oh, there was a robot inside a large glass cage that would perform pre-programmed tasks of stacking wooden blocks and then unstacking them. All automated of course and did nothing to charge up creative minds as had the old displays. Just graphics on the walls to appeal to the graffiti crowd of which Chicago has plenty. > That cutaway in Canada is "Gertrude" I believe....a real shame, had she not > been cut up there is no doubt the loco would have been a restoration > candidate. > > Cliff Ward > Cary, North Carolina > USA > > > -----Original Message----- > From: modeleng-bounce@xxxxxxxxxxxxx [mailto:modeleng-bounce@xxxxxxxxxxxxx] > On Behalf Of Jeff Dayman > Side note - there was also a cutaway full size Hunslet engine in the "old" > Ontario Science Centre in Toronto at that time.
