Welcome to the LT: Leonardo-Two Home Page



In the 1400s and 1500s, Leonardo Da Vinci became famous as an architect and painter. But during his life, he created a collection of Notebooks in which he recorded hundreds of scientific designs and theories, and he never publicised these.

This site is based on David Noel's conceit that his AOI.com.au website is an analogue of Leonardo's Notebooks, in that they contain a mass of theories, designs, proposals, and analyses which are not available elsewhere and often are in conflict with established ideas.

For the moment, the Leonardo-Two collection just lists scientific questions posed by others, and answers to these questions which differ in some way from currently-popular ideas.

Later, it is planned to accept questions on science matters from wherever, and provide answers where possible, particular where currently-popular ideas are less than satisfactory.
