[Beowulf] Intro question

[Peter St. John]

Vincent,
All the guys I know, myself, in finance, started in mathematics. Including
one Cole medal logician.  I'm sure there are some chemists and physicists
who got into finance also. I did myself, that was what sucked me into
software engineering long ago. we don't necessarily lose our theoretical
interests.
