That was not an easy one to find! I only got it because of the subject being recently treated on the "In Our Time" podcast. So thanks to Melvyn Bragg and his guests. The next round is now starting, hold on to the straps. The sentient baton suggests ABSTRACT.
Fun physics? No. Fun life? No, although humans have and have had a great interest in the AOTC. It's not an occupation, either. Earthbound? So far as anyone knows, only on Earth.
Observable? There are observations of this occurring. Economic? No. Aristotelian? Didn't know him personally, but the concept was almost certainly around then.
Biology? Arguments start among the audience. Life and death and so forth are all biological, but this is not usually considered to be a biological process. Rebirth? No, but the audience really like it. Appreciation is shown.
It's not metamorphosis, enlightenment is nice but completely off beam, "renaissance" is a good try but "the Renaissance" is totally wrong. The audience are collecting tomatoes to throw.
