“Science, freedom, beauty adventure: what more could you ask of life… …there was science in every curve of an airfoil, in each angle between strut and wire, in the gap of a spark plug or the colour of the exhaust flame” Charles A. Lindbergh, in Spirit of St Louis.
If you like the projects on this website, you might like to know about the many other Saturday Science projects and experiments in books. They are fully written up – with scientific analysis, suggestions for further developments, and even a little science history…

A Short SATURDAY SCIENCE Bibliography
Firstly, there are some great things in magazines, both on and offline. There is the wonderful Physics World, of course, and the broader appealing, more newspaper-level New Scientist. Don’t forget the short but excellent accounts written for businessmen in The Economist. And of course, don’t miss the STEM projects articles I have written with the guys at the IET for the Engineering & Technology magazine, contents are on the home page blog on this website :
https://eandt.theiet.org/tags/stem-challenges
Wikipedia, http://en.wikipedia.org is a fountain of knowledge – and one that you can contribute to, if you like. It really is good on anything that is not too controversial. The patent website espacenet http://worldwide.espacenet.com is an open publication of tens of millions of inventions – what’s not to like ? The legal language is a little tough sometimes, but there really is gold there.
These are a few of the great books we have enjoyed… more coming soon
- Jearl Walker, The Flying Circus of Physics, the surprising physics behind a hundred plus natural phenomena from sun-dogs to rainbows
- Keith Gibbs The resourceful physics teacher, lots of surprising demonstrations !
- Neil A Downie, Industrial Gases, The technology behind the industry that delivers everything from Helium to Xenon via Nitrogen, Oxygen and Argon and engineering at -200 degrees C
- Anson Cheung and Mark Warner A Cavendish Quantum Mechanics Primer, great readable introduction, with lots of great but readable math analysis.
- Charles A Lindbergh, The Spirit of St Louis. A great read, the story of Lindbergh’s epic flight across the Atlantic Ocean, and some of philosophy. A great read with lots of interesting and unusual science from isogonic lines to earth inductor compasses.
- Walter J. Moore, Physical Chemistry, tucked away in this old standard textbook are lots of fascinating phenomena you won’t have heard of.
- Horowitz and Hill, The Art of Electronics, the best book ever written on electronics.
- Edward de Bono, Six Thinking Hats is maybe the place to start on creative thinking. There are short summaries of Six Hats. Lateral Thinking, Creativity Step by Step is the old original from de Bono
- Simon Singh, The Code Book… all about secret codes – from simple substitutions to coding machines like the famous ‘Enigma’. Fascinating.
- Philip Steadman, Vermeer’s Camera a scientific detective story
- Steven Vogel, Cat’s Paws and Catapults, about the physics and engineering inside the world of nature.
- Mark Denny, Air and Water, more on physics and nature
- G B S Haldane, On Being the Right Size a nice essay on the importance of scaling and other potent ideas from an Old Master of science
- Adam Hart-Davis and Paul Bader, Local Heroes one of several very readable books by Hart-Davis looking at the history of science and invention
- James Burke, Connections, from Burke’s Scientific American column, detailing all the astonishingly connections between science and technology development
- Douglas Botting, Dr Eckener’s Dream Machine, the amazing saga of round-the-world flight in huge airships, in the days before long-distance airplanes
- David E H Jones, The Inventions of Daedalus, a Compendium of Plausible Schemes. Classic articles of imaginary inventions from the pages of antediluvian issues of New Scientist magazine.
- Dava Sobel, Longitude, a classic account of almost single-handed heroic struggle to create super accurate mechanical clocks. These were needed allow accurate navigation across the oceans, and avoid the once common and desperately sad losses of ships and their crews.
- Nick Thorpe and Peter James, Ancient Inventions. Some things were invented a VERY long time ago – a fascinating romp through the useful physics and engineering through time.
- T W Koerner, The Pleasures of Counting, a superb account of applying mathematics to the real world.
- Peter Goodhew, Teaching Engineering, a great account of the work Peter did to use project / problem-based teaching in the University of Liverpool in the UK.
