Welcome to my website, which fills some gaps in cyberspace with information about my career as a technical author and pages about my hobbies.
- Computer programming, mainly in Python
- My family history
- Historical linguistics
- The Voynich manuscript (I was one of a select group who said it was 15th century before the carbon dating)
- Scientific heresy
This home page will contain personal stuff such as
- My trip to the Voynich centenary conference at Frascati
- My visit to the Balcombe fracking protest
- Pet theories about things like the geology of the Wealden Basin
- The inventory of my ancestor Richard Sibbering, cordwainer, 1738. Not all my ancestors were poor.
