Wonder if you remember your Physics books ?
I had lost mine and now needed to recollect all those physics lab experiences. Some people keep these books and in good order – Glenys Thomson is one of them. Covered too, to protect the precious books. I needed them now, so they were lent to me with a sticker reminding me to return them. I guess she must be fond of them.
Going through them now…
hmmm…looks like we can lick most of these experiments with phones.
