I am also interested in the nature of fundamental properties
and laws. One of my older papers (which, incidentally,
got me this job but went otherwise almost unnoticed;
strange because it’s a good paper:-) deals with
zero-value physical quantities such as zero mass, zero
spin, etc. I argue that some such properties are not
mere “privations”; there is, for example,
a real difference between having zero baryon charge
and having no baryon charge at all.
Finally, I am interested in general philosophy of science,
cosmology, and (serious) music.
