Dear Prof. Dr. Lisa Randall:

Thinking about the Planck scale, watching your Barcelona presentation, *How Physics Scales the Universe*, and caught by your Suzanne Vega quote, “And what’s so small to you is so large to me, if it’s the last thing I do, I’ll make you see.” I was hoping you might give me a quick read of this page: https://81018.com/old-theory/ Thank you.

Warmly,

Bruce

PS. I suspect you have not looked at our chart of base-2 progressions from the Planck base units, particularly Planck Time to the current time. There are 202 notations. Now it is a very rough outline yet it is within shades of the approximate size of the universe within that 202nd notation. The universe acts like an ordered set. –BEC

Dear Prof. Dr. Lisa Randall:

I’ll be going back over your most recent work in an attempt to understand something new about quantum fluctuations. I’ll be starting with the Planck base units. I’ll go back to your work within the LBNL* and within your stories in *Warped Passages,* as well as the 1999 Structure Formation conference at the Isaac Newton Institute, Cambridge University, through to the Randall-Sundrum Model and all your other braneworld work, right on up to your most current, *Geometries with mismatched branes *(June 2020).

Eighteen other scholars are also being reviewed including Frank Wilczek and his 2001 articles touting Max Planck’s calculation of natural units in *Physics Today*.

John Wheeler’s quantum foam, Planckspheres, Planckbranes… I am more inclined to consider them infinitesimal spheres that bridge a dynamic finite-infinite relation whereby the infinite is only knows as continuities creating order, symmetries creating relations, and harmonies creating dynamics.That’s my one-note samba.

If you have any suggestions, of course, I am all ears!

Thanks.

Warmly,

Bruce

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 slowing down from the week-to-week support. However, as a result of those VOA-TV broadcasts, I am also 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 take 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 and 13.79+ billion years.

Meaningful? An interesting way to look at the universe?

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

Thanks.

Warmly,

Bruce
