It is so nice to have grown up children who can talk to you adult-to-adult. Over supper, husband, daughter and I were discussing showers, the difference between showers and baths, and the hygiene of showers. This involved explaining fluid dynamics with reference to Bernoulli. Have you heard of his work? He studied and explained how differences on pressure affected water and air flow and his theories are relevant to gliding, and to shower curtain hygiene. This principle explains why gliders fly, and why shower curtains gather germs, and it's fluid mechanics that you would study at honours level in mathematics or physics. Daughter did not wince a moment when husband explained the theory and he gave me a thumbs up when I asked, "when you have a shower, what does the shower curtain do? Does it move in or out? That's the effect that Bernoulli models"
Similarly, decades ago, at meal time, I mentioned something about educational theory - Piaget's ideas of how a child saw and compared volumes when asked. My teacher mother exclaimed in delight that now there was someone in the family who knew what she was talking about.
Isn't a pleasure to be able to discuss ideas with your grown-up family?
