Peter Barrett is a genius, or must be. He figured out, from the Japanese instructions, how to get useable data out of the photo sizer. It’s complicated, but learnable.

I feel like I’m doing an experiment. Weighing sieve fractions, finding per cents, being careful with procedure. Dr. Treves took yesterday’s largest size and the per cents I did to look at. Maybe this is what writing a paper is all about. Just like writing up an experiment.

Spent the afternoon learning the photo sizer. By guessing at the size range you want analyzed, you figure out the “h” setting from an equation dealing with Adsorption, Density, Viscosity, etc. Then you take your chart record. Plot the Delta recorder position, multiplied by the midpoint of Delta-Tee (which is Delta Mu from a graph depending on which Tee you use). This is your partial fractions, which can be computed into percentages.

Peter met Peter.

Peter B. needed probability graph paper. Nobody around here has heard of it.

Boston lost in ten innings.

It occurred to me today that the price for eternal peace is eternal wishy-washiness. There can be no conviction where there is no conflict.

We got the go-ahead to drill IA. Hurrah!

The trackmaster was only a mile off-shore when it went through. It was an accident that could not have been prevented nor occurred by negligence.

The big long print paper to do the mural on didn’t develop right. So instead of wasting six hours in the dark room, I printed some of the negatives as 8 by 10s. Three of Mount Debrushka from the air, one of the site, and a couple of Mount Discovery and the Daily Islands. I wrote this whilst they washed.
