Dear Lisa: (This email has not been sent; it is still being formulated.)

I make a reference to the 1999 Structure Formation conference at the Isaac Newton Institute, Cambridge University and found that you were among the very chosen to attend. Of course, Warped Passages soon followed. It was the same time Frank Wilczek was touting Max Planck’s calculation of natural units in Physics Today. It took awhile before Planck’s work was finally accepted within the core of science. I was pleased to find your extensive analysis within Warped Passages and the Randall-Sundrum Model of the Planck scale..more to come

Was John Wheeler correctly grasping the future when in 1986 he said, “Behind  it  all  is  surely  an  idea  so simple,  so  beautiful,  that when  we  grasp  it  — in a decade, a century, or a millennium — we will all say to each other, how could it have been otherwise?”

PS. You might remember that back in and around

Hi Lisa,

With Warped Passages on my left, I just finished watching several of your videos over at BigThink.  It is an excellent platform to begin getting educated to do a docudrama.

I have a question about base-2 notation from the Planck length, but first the background story…

You may remember that with my wife, we were the founder/producers of a weekly, half-hour show that aired on PBS stations throughout the USA and on the Voice of America TV around the world. We have slowed down from our weekly productions. After 14 years (over 50 seasons), we stopped new productions in 2009; PBS had license to them through 2012, so even now I am still slowly down from the week-to-week support. However, as a result of those VOA-TV broadcasts, I am now working within several countries to test the idea of their own local model of that show. It keeps me too busy.

Over a year ago I had a chance to get back into the classroom — high school geometry. I was the sub for a nephew and did a simple lesson on the platonic solids. Then, they asked me back (December 19).

I was thinking about nested and combinatorial geometries and wondered, how many notations back would it be to get to the Planck length. 112 divisions later I was there… thinking about Phil Morrison and the Powers of Ten. We then multiplied out and found in about 90 multiplications-by-2 we were somewhere around the edges of the observable universe.

Meaningful? An interesting way to look at the universe?

I thought you might take a minute to give me a quick answer.
