My specialisation on Wikipedia is rapidly becoming 1920s electronic filter designs and designers. I know, this is sadly narrow and it is also not what I had set out to do on Wikipedia. Quite by accident, I discovered that there were virtually no articles in this field and co-incidentally, I happended to know a great deal on the subject. It seems that for every article I write, another three are suggested by the process of writing. Perhaps there will be an end to it one day, but at the moment it looks like it will go on forever. For variety, however, I also write articles on sequential move puzzles (and virtually anything else that takes my fancy).

[edit] Interests

Spinningspark is an electronics engineer working in the communications field. His interests include;

• Ancient History
  Especially the Roman and post-Roman periods and the early formation of European nations.

• Science
  Spinningspark is interested in the hard sciences, especially theoretical physics and the philosophy of science. Spinningspark takes part in the Search for Extra Terrestial Intelligence (SETI@Home) distributed computing project. If you wish to take part in this project you can go to the SETI@Home homepage here [1]. If you would like to see my results from this project then go here [2].

• Mathematics
  Spinningspark is interested in all kinds of mathematics. He is currently active in several projects searching for new prime numbers. Amongst these is the search for new Mersenne primes. The Great Internet Mersenne Prime Search (GIMPS) is a distributed computing project which anyone with an internet connection can take part in. If you wish to take part in this project you can go to the GIMPS homepage here [3].

• Games and Puzzles
  Spinningspark loves puzzles of a mathematical or logical nature. Spinningspark hates puzzles that rely on a linguistic pun or other kind of "cheat" to make them work. Spinningspark is a speed solver of Rubiks cube and had written computer programs to solve the cube. Never managed to get the computer to solve as efficiently as a human though. Spinningspark has a large collection of Rubiks puzzles of many shapes and geometries.

• Ice Skating
  Spinningspark likes to ice skate (artistic, not hockey) and has skated competitively.

Spinningspark also occasionally contributes to aeronautical articles. He holds a Private Pilots Licence (PPL) but is probably in the top 100 most incompetent pilots in the UK, if not the world. US readers will be delighted to learn that he no longer does any flying in that country.
