Deriving Hubble's constant from fundamental constants
Deriving Hubble's constant from fundamental constants launched on July 12, 2021 with 62 votes, #1,153 of 3,502 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 5 years on.
In plain words
This is a computational tool that derives Hubble's constant from fundamental physics constants. Available as a Google Colab notebook, it allows researchers and physicists to explore the mathematical relationships between fundamental constants and cosmological parameters. The work launched in 2021 and is designed for anyone interested in theoretical physics calculations and cosmology.

I was reviewing Dirac's Large Numbers Hypothesis (https://en.wikipedia.org/wiki/Dirac_large_numbers_hypothesis) and decided to give it a second go, now with measurements of fundamental constants more precise than 100 years ago. And I stumbled upon a value for Hubble's constant that's uncannily close. Here are the full calculations. https://colab.research.google.com/drive/1K1qoUFvqZp1fWbpcKJWq63nflgwS0ZHh?usp=sharing Meaningless, or meaningful coincidence?

I was playing around with fundamental constants and out popped 13.8 billion light years. What is going on? the wavelength of an electron mass photon / (2pi) * the charge radius of a proton / the black hole radius of a proton = 13.8 billion light years ((h / (m_e * c * 2pi)) * (h / (m_p * c * pi/2)) / (2G * m_p / c^2)) = 13.8 billion light years…

Hi everyone, here's a web app I made that generates code for efficiently approximating mathematical functions. This is useful when performance matters more than perfect accuracy, for example in embedded systems. The app uses Chebyshev expansions, which despite their theoretical depth result in suprisingly compact and readable code in practice. This code is generated for you and using it does not require any knowledge of the underlying theory. Source code and more info: https://github.com/stuffmatic/chebyshev-calculator
