Workshop about Q in school
I am attending a very interesting workshop with many secondary school teachers of Switzerland. It’s in French, but I blog on it in English. Today, two notes:
Jean-Marc Levy-Leblond has presented a nice conceptual framework to understand how the notion of “wave-particle duality” arose. He pointed out that the classical notion of “particle” is discontinuous (or discrete) both in its spatial extension and in its quantity; the classical notion of field is “continuous” in both. The “quantons” (he likes this term, and it’s practical indeed) are continuous in spatial extension but discrete in quantity.
A nice hint… but no need to expand: he immediately said that, nowadays, the notion of “wave-particle duality” should just be erased forever from our vocabulary — on which, I cannot agree more.
This is just devoted to state my admiration for the teachers I talked to (to be extended by extrapolation to all the participants). With some, I even ended up talking already of the latest results of axiomatics, of device-independent, of indeterminism… I’ll blog about these ideas one day. Now it’s dinner time.
