Dear friends:

Thanks a lot for your information.

Thomaspin: I guess you are a scientist in the real life :-) Your technical presentations of car repair procedures are very clear, methodical, and to the point.

Some science history text books claimed that the Einstein was the best theoretical physicist but also the worst experimentalist (he would break things if he went to a laboratory). Ernest Rutherford was a complete opposite of Einstein (The famous Rutherford formula regarding alpha particle scattering was actually formulated by one of Rutherford's assistants, but the boss always took credit for everything :-). However, Enrico Fermi excelled in both theoretical and experimental physics.

Best regards,

Eric
