Dear Jack,

Thankyou for the letter dated 5th January 1999. No doubt you recall that we discussed the fax, in December, by phone. You asked me to e-mail you a more detailed and clearer elucidation that would be more accessible to readers. I actually carried out your instructions and e-mailed it to you on the 30th of December 1998. I am resending these 2 pages together with this one.

As far as the accuracy of numbers in the MME... this has been gradually improving over the past 111yrs (eg. Some time ago it became possible to do the MME with lasers)... And now that I have invented the "Summation of Series" I can do it as accurately as I like... Remember this is a modified Michelson-Morley carried out by myself (eg. The lab arms, which were originally 11m, were changed to 10.83079918m and the absolute "Perpendicular" arm was made 11m).

Another point to consider is that in my original paper, I tried to do it both Algebraically and Arithmetically: Algebraically is fine but it does not illustrate much of what is going on... on the other hand, Arithmetically illustrates a great deal but unless you use a great deal of decimal places, you can leave a very imperfect picture in the readers' minds. (eg 1 Kings 7:23; Pi to one significant figure... today Pi to many significant figures!).

Yours Sincerely, Frank P. Russo

P.S. Michelson in 1887 with his interferometer could detect as small as 2.75 x 10-9m. ie 0.01 of a fringe... I am simply being consistent in my "imaginazione exp."
