The terms “anode” and “cathode” were first published by Michael Faraday, F.R.S. in 1834. A delightful (and highly recommended) historical account of how these words were conceived by Faraday and his associates can be found in Faraday Consults the Scholars: The Origins of the Terms of Electrochemistry by Sydney Ross . As scientists have learned about how electrochemistry works, the definitions have evolved somewhat. The following is a brief summary of their etymology and their meaning as it stands today in electrochemical circuits. In the course of my own study of electrochemistry, I thought other students may find this information helpful in keeping everything straight.
A question has been going around the social networks: If kinetic energy is converted to thermal energy upon impact, how hard to you need to slap a chicken to cook it? One response suggested raising the chicken’s temperature to 400 °F, which is far too hot, and it used an “average slap energy” that was not explained. Here then, is my analysis.
Should quantum physics e’er be standardized,
when taken in a thought experiment,
its terms of meaning judged and analyzed,
absurdity prevails, not merriment.
A cat both dead and living cannot be.
That was the point old Erwin tried to make.
To measure is to interfere, you see,
some photon must be thrown to cause a quake.
Awareness cannot of itself crash waves;
By heat and light, the box became a grave.
It is midsummer, and dozens of people have come to this place, known as Externsteine, to celebrate the longest day of the year.
