Dear Prof. Dr. Michael Duff:

In your 17 Dec 2014 arXiv “fundamentals” article (indexed above), you say,
To measure the speed of light we need a clock and ruler: if the distance between the notches on our ruler is the distance light travels between ticks of our clock then c = 1 whatever our theory and will remain so until the cows come home.”

Though true, might we also take Max Planck’s simple formula for Planck Time and confirm the speed of light through simple division.

It appears to be true throughout all 202 base-2 notations as evidenced here within line 10 on our horizontally-scrolled chart: https://81018.com/chart/

Thank you.

Most sincerely,

Bruce

PS. At c=1 within this configuration, the Planck Length multiple divided by the Planck Time multiple (which is between  Notations 143 and 144) is as you’d expect 299,792+ km.

Dear Prof. Dr. Michael Duff:

On chasing down a reference to your most-challenging work, I chided myself, “Go over this one more time.” And then puzzled, asked, “Have you ever written to Michael Duff?” Looking it up, indeed, I had. Twice. Almost a year ago and then again, almost three years ago, so with another rebuke, I concluded, “Put those notes up on the site so you can see what was written and what Duff references prompted those brief notes.” That reference became this page: https://81018.com/duff/

Our work is simple and has a simple logic, but it doesn’t seem to stand to reason.

First, there is our map (or base-2 chart) of the universe from the Planck base units to this moment in time… “a simple logical construct.” Multiplication is multiplication. The Planck units are the Planck units. The 202 notations make it a construct. So I ask, “How is it that it does not follow… that it’s just a bunch of numbers?” Reference:  https://81018.com/chart/

Second, in the analysis of those numbers, many things seem to fall into place.  Should I could go on? Thank you.

Most sincerely,

Bruce

Dear Prof. Dr. Michael Duff:

Could we assume the Planck base units of length/time and mass/charge
are the first manifestation within space time? Could it naturally double and
continue doubling until in 202 notations it was out to the size and age of
the universe?

I struggle with that rendering: https://81018.com/growth

Could you help me understand why this is an impossible construct?
Thank you.

Most sincerely,
Bruce

Dear Prof. Dr. Michael Duff;

We need all the help we can get.

We went off course in 2011 when we chased a tetrahedron inside, dividing the edges by 2, over and over again, until in 112 notations we were within the Planck scale. To get out of that tight space, we reversed ordered and multiplied by 2 using Planck’s chosen numbers. By the 202.345+ notation we were out to the age and size of the universe. This happened in a high school in New Orleans.  A little history of our work is here: https://81018.com/home/

So what do we do now? We were told, “Nobody has done it.” “Nonsense,” we reply. Our simple geometries and simple base-2 pre-conditioned our thinking, we thought, “It’s all too simple. There’s got to be a catch.”

Here is my history: https://81018.com/bec/ (nobody special)
Here is my nonsense: https://81018.com/2016/06/01/quiet/

Will you guide us back to sanity or do you think there could be something here? Thank you.

Most sincerely,

Bruce

PS. I had a project at MIT long ago that kind of anticipated this development:

Not for the general public…

“Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings. This last year has witnessed a new shift of equal proportions: perturbative ten-dimensional superstrings have in their turn been superseded by a new non-perturbative theory called {\it M-theory}, which describes super membranes and superfivebranes, which subsumes all five consistent string theories and whose low energy limit is, ironically, eleven-dimensional supergravity. In particular, six-dimensional string/string duality follows from membrane/fivebrane duality by compactifying M-theory on S1/Z2×K3 (heterotic/heterotic duality) or S1×K3 (Type IIA/heterotic duality) or S1/Z2×T4 (heterotic/Type IIA duality) or S1×T4 (Type IIA/Type IIA duality).”
