________ Harmonic Analysis on Reductive Groups

(NOTE: A conference on Harmonic Analysis on Reductive Groups was held at Bowdoin College in Brunswick, Maine from July 31 to August 11, 1989. The stated goal of the conference was to explore recent advances in harmonic analysis on both real and p-adic groups. It was the first conference since the AMS Summer Sym­posium on Harmonic Analysis on Homogeneous Spaces, held at Williamstown, Massachusetts in 1972, to cover local harmonic analysis on reductive groups in such detail and to such an extent. While the Williamstown conference was longer (three weeks) and somewhat broader (nilpotent groups, solvable groups, as well as semisimple and reductive groups), the structure and timeliness of the two meetings was remarkably similar. The program of the Bowdoin Conference consisted of two parts. First, there were six major lecture series, each consisting of several talks addressing those topics in harmonic analysis on real and p-adic groups which were the focus of intensive research during the previous decade. These lectures began at an introductory level and advanced to the current state of research. Sec­ond, there was a series of single lectures in which the speakers presented an overview of their latest research.

Dear Prof. Dr. William H. Barker:

My work in 1972 focused on continuity, symmetry, and harmony. I was attempting to define what I thought would entail “a moment of perfection” within our quantum universe. By 1980, after working with an array of distinguished scholars in Boston, Cambridge (USA), and Paris, I went back to work within a business that I had started in 1971. From a little service bureau, we soon had a software business with well over 100 employees. My first opportunity to attempt to dig back into it all back was in 2011. I was helping a nephew with his high school geometry classes when we went inside the tetrahedron — https://81018.com/tot/ — and then its octahedron, step-by-step, deeper and deeper by dividing all the edges by 2 and connecting those new vertices. Within 45 steps we were within particle physics. In 67 additional steps, we were within the Planck scale. By multiplying those classroom objects by 2, in 90 steps we were out to the approximate age and size of the universe. Instead of base-10 like Kees Boeke (1957), we used base-2, we had an inherent geometry, and we went from the Planck units to the current time.

It was an unusual, albeit, rather idiosyncratic chart of 202 notations: https://81018.com/chart/

Prima facie, do you see any merit to such a chart?

I will continue my readings of your work, Continuous Symmetry: From Euclid to Klein (AMA, 2007) and Harmonic Analysis on Reductive Groups (Springer, 1991) in hopes that you might have some guiding thoughts for  this rather idiosyncratic chart of the universe.  Thank you.

Most sincerely,

Bruce

Dear Prof. Dr. William H. Barker:

My grandmother lived up the road a ways (Bremen…Damariscotta, then out to 1A and the coast). Often Dad would stop at Valerie’s in Ogunquit, my sister’s favorite restaurant; they shared the name. We’d fall quickly back to sleep as children for the final long slog up from Cambridge. For some magic reason, I would awake just as we were passing by Bowdoin. Bathed in the soft summer lights, I would secretly dream, “That’ll be my school.”

1965 came quickly and I marched off to the south to register voters, but Bowdoin always held that special place.

Today, I am delighted to find your book on continuous symmetries and remember my childhood once more. Images imprint the soul and make us who we are.

When and why is there spontaneous symmetry breaking?
Have you given it much thought?

So, I have discovered your work and I am grateful to now be taking a de facto course with you through your writing. And so I say, “Thank you!”

With warm regards,
Most sincerely,

Bruce

________________

How does one find your work:  https://en.wikipedia.org/wiki/Continuous_symmetry
In mathematics, continuous symmetry is an intuitive idea corresponding to the concept of viewing some symmetries as motions, as opposed to discrete symmetry, e.g. reflection symmetry, which is invariant under a kind of flip from one state to another.

Formalization
The notion of continuous symmetry has largely and successfully been formalised in the mathematical notions of topological group, Lie group and group action. For most practical purposes continuous symmetry is modeled by a group action of a topological group.

One-parameter subgroups
The simplest motions follow a one-parameter subgroup of a Lie group, such as the Euclidean group of three-dimensional space. For example translation parallel to the x-axis by u units, as u varies, is a one-parameter group of motions. Rotation around the z-axis is also a one-parameter group.

Noether’s theorem
Continuous symmetry has a basic role in Noether’s theorem in theoretical physics, in the derivation of conservation laws from symmetry principles, specifically for continuous symmetries. The search for continuous symmetries only intensified with the further developments of quantum field theory.

Dear Dr. Kristina Starklofft:

Congratulations on all that you doing to preserve the best among our scholars.
I have a deep and abiding affection for Max Planck and his base units.

MaxPlanck1947Is it your office where the Vetter printing of Max Planck hangs today? Does your museum/library gift shop sell a replica?
So entirely delightful. That it was painted in my birth year, 1947, is sweet. That it is an artistic image, probably the last prior to his death, gives it even more vibrancy.

How very special.

May I use it with our website?

Though Freeman Dyson and I go back to work in 1979, I remember writing to you in and around 1970! I am getting too forgetful and these postings are a way for me to check on my most recent communications with a person. If you would like anything changed, updated or deleted on this page, just let me know and I will be as expeditious as possible. Thanks.

Hi Elizabeth –

I just updated the Wikipedia reference under “Personal Website” from
https://elizabethrauscher.net to https://elizabethrauscher.org
It’s now going to the correct page!

I just came upon the work of Nassim Haramein where I learned about his
Unified Field And Sacred Geometry that you were attempting to write
a scaling law essentially to encapsulate the universe. How is that going?

Might the 202 doublings of the Planck base units to the Age of the Universe
and the size of the universe be a simple solution? Perhaps too simple, at least
it is a start: https://81018.com/chart

Thanks.

Dear Elizabeth:

We corresponded back in the ’70s. Noyes, Bastin, Bohm were all mutual friends. My interim story is too arduous, perhaps for another time.  You have been prodigious. What a vitae!

In 2011 in a high school I had the five geometry classes go inside the tetrahedron and octahedron. Dividing by  2, this perfect, interior tessellation brought them face-to-face with the proton in just 40 steps, and then face-to-face with the Planck base units in another 67 steps.  A sweet journey it was.  In our next time together, we multiplied by 2 and in about 90 steps we were out to the edge of the universe, well beyond Kees Boeke.* 3.33 times more granular with imputed geometries and the Planck base units, what was not to love about it?

The project got away from us and has it own life:
/https://81018.com/chart
That link goes to a rather large, horizontally-scrolled file.

Is it all wet? …too idiosyncratic? …too simple?

I thought you would find it of some interest, if just as a novelty. A penny for your thoughts? Thanks.

Most sincerely,
Bruce

cellular reproduction and bifurcation theory, nor does it engage
cellular automaton, or the automorphic forms of the Langlands

Dear Prof. Dr. Björn Engquist:

Not being a scholar or expert, I am still fascinated with your work to define the development of absorbing boundary conditions.

We began our work in a high school geometry class where we were observing how an octahedron is in the center of a tetrahedron with half-sized tetrahedrons in each corner. Within the octahedron, there is a half-sized octahedron in each of the six corners and a tetrahedron in each of the eight faces all sharing the centerpoint.

We decided to do a Zeno-like progression and applied base-2 going back deeper and deeper inside. In 45 steps we were in the range of particle physics, and in another 67 steps we were in the range of Planck’s base units.

We then decided to multiply by 2 and in 90 steps we were in the range of the age and size of the universe.

For high school people, it was great fun. We encapsulated the universe in 202 steps. We only then found Kees Boeke’s work and began thinking of the differences between base-10 and base-2.

I suspect that you are one of the few people on earth who has thought very deeply about computational multi-scale methods. Might you advise us? Are we being illogical? Are we doing something wrong? Thank you.

Most sincerely,
Bruce

Dear Prof. Dr. Weinan E:

I don’t think we did a very good job teaching geometry. In 2001, after spending a few hours with John Conway there in Fine Hall, he asked me, “Why are you so hung up on the octahedron?” I answered, “Because nobody knows what is perfectly enclosed within it.” I continued, “…we don’t know its most simple interior parts. …we don’t know about its four hexagonal plates. …we fail to recognize its necessary relation with the tetrahedron. Shall I go on?”

Ten years later with a high school geometry class we went deep inside that tetrahedral-octahedral complex. In 45 base-2 notations going within, we were well within particle physics. Within another 67 notations we were within the Planck Scale. We went back out; and from the desktop, it was only 90 additional doublings and we were at the approximate age and size of the universe. We then discovered Kees Boeke’s base-10. It had no inherent geometry. It had no Planck scale doublings. It was an empty shell while we had the dynamics of cubic-close packing.

We later learned that we had the penultimate multiscale model. Would you classify it as part of your heterogeneous multiscale method (HMM)?

Now, regarding all this data, there are three pages about which I would enjoy your harshest judgments:

Dear Prof. Dr. Matthew R. Francis,

Is simplicity good?

We took the Planck base units of Length, Time, Mass and Charge and
applied base-2 exponentiation. In 202 doublings, the chart is out to the
Age of the Universe. It seems straight forward, however, the results are
rather startling.

First, it is a simple, logical, mathematical map of the universe.
I am not sure… are there any others?

By studying the numbers associated with each doubling, we see
that most of the 202 doublings are about the early universe.
Notation 143 contains the first second.
Notation 197 contains the beginning of large structure-formation.
All the numbers are here: https://81018.com/chart/

Though entirely idiosyncratic, I think there is something here.

1. Of course, the Planck Length doubling at one second, divided
by the Planck Time doubling at one second is very close to the value
of the speed of light in a vacuum. It is consistent with Planck’s initial
equation for Planck Time. Yet, it is naturally also consistent within
each of the other 202 notations.

Thus, space-and-time appear to be derivative, quantized, and discrete.

2. There is a natural inflation that mimics the ΛCDM model.

3. All notations appear to be forever active and necessarily
interdependent and appears to define the Now for Richard Muller
and Carlo Rovelli.

We started this project in a high school geometry class in 2011
( https://81018.com/home/ ) with just the Planck Length. We
did not introduce Planck Time until 2014 and Planck Mass and
Planck Charge until 2015. So, really we have just begun to study
and attempt to understand these numbers in light of current theories
within cosmology and physics. It is entirely provocative!

Even though it is idiosyncratic, is there any hope for it?
The current homepage is my latest attempt to spotlight key ideas
and problems. Thank you.

Most sincerely,
Bruce
