Vintage bike Science poster
 
I work as a Middle school custodian , the teaching is online due to covid right now so the teachers have been getting rid of things they no longer use. One of the Science teachers put this 1988 poster in the trash today the bike is a Raleigh it's had to read the model but I think it says Grand Prix. I am going to find a spot for in on my garage wall.

Must have been quite educational for its maker, too.

The illustrator should have had a coach, mentor or teacher.

I'm really into the basic physical science of the bicycle like this: wheel, axle (spindle), lever (leverage), screw (threads), etc. One simple wonder that I don't take for granted is the ability for two nuts to lock together on a threaded bolt. At its most basic level, that's how a bicycle works. And I guess this is why I love rebuilding vintage bikes: I know how everything works. It's all so simple. The most basic things can be the most practical and beautiful. Fortunately, they can also be fast and fun.

When you're a kid, sometimes it takes the strangest small thing to spark interest. (I hope that's one reason school is supposed to expose kids to a variety of subjects). I wonder how may kids got motivated to get into cycling or mechanical arts after seeing that poster.

that is pretty cool. Like the paintings of ancient hunting rituals on a cave wall. Evidence of lost skills.

Add the magic of the pneumatic tire, the ever-present friction, and the physiology of human power generation and you've pretty much got it.

"Half a cent per ton-mile"

This is a reference to historical freight rates for carrying grain that will make sense only to Canadians of a certain age and has nothing to do with cycling, but I learned about it around the same time as Scientific American published its article describing the efficiency of the bicycle. It seemed to embed in my mind as a nice cross-metaphor. A meme we'd probably call it today?
