This study attempted to see how giving a cup of coffee, or not giving a cup of coffee, to 22 old people would affect the balance of those old people. The study is: “The acute effects of coffee ingestion on postural control and physical function in older adults: A randomised crossover trial,” Darren L. Richardson, […]
David Jones some years ago assaulted humanity’s embarrassing lack of understanding of why moving bicycles are so stable. Jones performed a series of experiments, from which he learned some surprising things. He revealed them in this article: “The Stability of the Bicycle,” David E.H. Jones, Physics Today, April 1970, pp. 34-40. (Thanks to Catherine Klauss […]
Attention horse owners/riders: Does your horse sometimes have the inclination to lean the ‘wrong’ way when ridden? Have you thought about fitting it with a set of gyroscopes? Inventor Greg Collier, of Lubbock, Texas, has been granted a new US patent which might go some way towards alleviating equine equilibria insufficiencies. “This disclosure relates generally […]
There’s still some physics mystery, for many people, about how a bicycle balances. Bill Steele wrote about the physics of bicycles balancing themselves, for Cornell University’s Ezra magazine. Nicole Frýbortová demonstrates, in this video, something about how a human rider balances on a bicycle:
