The Deceptiveness of Coincidence

A friend of mine recently posted about a chain of events - people sharing birthdays - that was so unlikely that a lottery ticket purchase was called for. Most people might make similar comments as the oddity of these events struck them. There followed some discussion about these problems and it made me think of […]

Academic Family Tree, LaTeX and Tikz

A few years ago, I found out some information on my academic genealogy, going through my supervisor, Brian McMaster, back through others to G.H. Hardy, Newton and Galileo and a little further before the records run dry. Of course it is nice that mathematics is an old and well established discipline with great records. And […]

Tweaking Newton's Law of Universal Gravitation

I answered a question on Quora about the consequences of Newton's law of Universal Gravitation being in inverse law and not an inverse square law for 60 seconds. The outcome is not so good, what with all matter acting as a black hole and all. What would happen if the law of gravity becomes ~1/r […]

Aikido in Dead Straight Lines

There's been an elephant in the room on my blog for quite a while now, and it has prevented me completing a number of articles that I have had in draft for some time. A bit over a year ago, my friend and mentor, Alan Ruddock died. I've been trying to articulate what that meant […]

Tau versus Pi

Today, two of my friends independently sent me a story about Tau Day which I had hitherto never heard of. One of them asked for me comment about whether this had any point to it. At first I thought the article was just mathematical trolling, thought about it a bit more, thought there might be […]

The Academic Descent to Me

How interesting, today I learned that Derek Burgess, the PhD supervisor of my PhD supervisor (Brian McMaster) was himself supervised by Frank Smithies. With a little help from the Mathematical Genealogy Project this has helped me work out my academic "parentage". Colin Turner, Queen's University of Belfast, 1997 Brian McMaster, Queen's University of Belfast, 1972 […]

More about LHC black holes

Last week I wrote a little about the size of black holes, and incidentally discussed very primitive calculations I did on the lifespan of any black hole created by the LHC. A few days later, this interesting article showed the results of professional physicists on just how little such little black holes could grow, in […]
