Anyone know what's being worked on here?

Oh, they are just writing down all the equations to determine position versus time for a simple Keplerian orbit. The top bit (in yellow) is using Kepler's equation to determine the position on a 2D orbit, the white in middle then applies that to a 3D orbit in equatorial coordinates, and then the bottom yellow puts everything in an explicit form that they could stick in the computer.
Also note that it is set up in the parking lot with parking lines at the bottom of the photo and sun shadows around the ladder.Like it anyway.
This is a great photo that bringing back the days of chalk talks. I recall an interview with IBM when it was made very clear that the "uniform" seen in the photo was the expected uniform. As much as it convays the tenor of the "old days" I have to believe it is a totally staged photo. First no one would choose to have a board that required you to climb a ladder when you could rotate the board. I have to believe that the portrait format fits Life's page format (Life in bottom right).Also note that it is set up in the parking lot with parking lines at the bottom of the photo and sun shadows around the ladder.Like it anyway.
I wonder if Powerpoint is actually an anti-productivity tool?

How about overhead projectors? Weren't those the Powerpoint predecessors before affordable LCD projectors began to emerge. Only exception that anyone who could write and draw could easily create slides/transparencies and edit them on the fly if needed.

They probably have those "smart boards" now in a lot of schools.
