(Last updated 2014-08-23.)

I am mostly interested in making scientifically important observations, like timing occultations of or by Solar System bodies and measuring variable stars.

I am also interested in citizen science projects and participate in some of them, like Galaxy Zoo.

I have been an amateur astronomer since 1975 and have worked at the European Space agency's (ESA) technical centre in Holland, ESTEC, on the ARISTOTELES mission, an earth gravity mapping mission.

Approximate coordinates: 55°20 N, 10°20 E

revised Why did Compton use X-rays in his experiment?
Some copy editing (but more could probably be done, e.g. near "less present". And perhaps some MathJax'ing).

comment Why didn't the Big Bang create heavy elements?
So if all atoms in the universe started out of lead atoms, would they extremely quickly be split to elementary particles (before the universe could cool down sufficiently)?

revised Confusion about 1-forms as introduced in “Gravitation” (Kip S. Thorne,…)
