Congratulations on your work and success to reformulate the kilogram standard. Outstanding.
We are high school people who have been thinking about standards for many years. It began in 2011 with our extracurricular activity. We followed the Planck base units by applying base-2 (simple doublings)to emerge with 202 notations. If Planck time is assumed to be the first moment of time, the current moment of time falls within the first part of notation 202. https://81018.com/chart/
First, we began to think that a multiple of the Planck Length might make a good standard. A NASA scientist https://81018.com/2012/06/14/kolecki/ thought it was an interesting idea. The more we studied the numbers, we also thought a multiple of the Planck Time would make a better standard than the cesium 133 atom calibrations
I’ve written a little about it here: https://81018.com/formulas/
That we are way over our heads is an understatement, but there is a special logic that keeps pulling us forward. Thanks.
