Catastrophe

I am retired early and interested in everything from the Big Bang (and before) from Cosmology to Astronomy and Planetary Sciences to Geology including the 'geology' of exoplanets and miscellaneous objects including asteroids. That covers quite a large field and keeps me very busy. I have a science orientated B.Sc. (Chemical Engineering).
I have been fairly fluent in French and German, having travelled frequently in both France and Germany whilst working. I am revising these, but also learning Russian to keep that hemisphere.
