Saturday 5 April – Train to London, What To Do with Three Hours in London? Plane Home

On the train at Manchester the accents wash over me. 

“Youe go’ u’ early todey innit?” 

What to do with three hours in London? Roll a dice on Monopoly board. Euston Road to Kensington.

And here I am.

This is a 1543 edition print of a book by Vetruvius, a Roman architect. He emphasised Mathematical symmetry and perspective in architectural beauty. It less than 100 years from the time of Da’Vinci – and he would have read an earlier print of this book, when producing his work the Vetruvian Man.

This is a Sextant and book of Log tables they used on ships for navigation.

This is a fragment of Charles Babbage’s Difference Engine (The Log Tabulator). He would have used it for obtaining further funding. It indicates that his complete machine was never built.

This is a slightly bigger but still incomplete version (of the Log Tabulator) done by this son after his death using parts that he found. You can see a book of log tables next to it.

This is a complete reconstruction of the Difference Engine (log tabulator) built in 2002 by Computer-Engineer historians.

This is a part of the Analytical Engine (enables numbers to knit numbers) that Charles Babbage completed. Plans show that if completed, the final result would have been much bigger.

This is a calculator/computer that Lord Kelvin (William Thomson) built to predict tides. Some have called it the first Victorian Computer.
