Wordless Wednesday

I've worked as a scientist for the last 30 years, at various universities, a large home and personal care company, a startup in Liverpool called The Sensible Code Company (formerly ScraperWiki Ltd), GBG and now as a consultant in data science.

I write about:
* the books I have read, typically science and history (or both), partly as a reminder to myself and partly as a review;
* science, things I have done or things I find interesting;
* technology, programming and gadgets;
politics, and current affairs;
* ...and other stuff as it takes my fancy - holidays, photographs and things I want to remember.
