Something new: STEAM activities for the Covid-19 lockdown!

Yes, the Playwiths have been converted into a book.

The Playwiths began in about 1995, and a couple of years back, I was urged to make a book of them.

I did, and my friends liked what they saw, but the publishers didn't. Frightening economic times, they said.

Well, I went ahead and did it in three forms:

  • a lo-res freeby PDF with very relaxed copyright;
  • a high-res low-price commercial PDF for the Kindle;
  • a paper and ink book from Amazon (tax laws won't let it into Australia);
  • did I say three? I lied. The paper version is half-tone, but soon there'll be a full colour version.
But don't worry, this web version stays here anyhow.

SPLATS about Chemistry

For an explanation, see the main splats page

  • We and our surroundings are made of matter, influenced by energy. All matter and all energy comes from stars: we are made of very ancient star stuff.

  • Chemical groups have set properties, which may be related to their shape, their charge, their preferred charge, their charge distribution, and their size.

  • We can explain the chemical behaviour of matter in plants, animals, rocks, oceans and the test tube, just by understanding how matter is put together.

  • All modern chemistry is based on the atomic theory that the behaviour of matter can be explained by assuming it is made of particles, either atoms or molecules.
