20200516S Santa Cruz, CA: In the search for absolute truth about reality and the universe, I find it enlightening to take note of dimensionless values. These are also important from a universe surfing point-of-view because they will be the same in all universes (or at least all universes obeying the same fundamental physics as our universe). Dimensionless constants do not depend on arbitrary measurement standards, such as grams, meters, or seconds.

Some articles that caught my interest for future study are:

1. Ask Ethan: What Is The Fine Structure Constant And Why Does It Matter?
2. Four direct measurements of the fine-structure constant 13 billion years ago
3. Most Accurate Determination of the Fine Structure Constant
4. Why the number 137 is one of the greatest mysteries in physics
5. Fine-Structure Constant from Sommerfeld to Feynman
6. Twin Concept of Fine Structure Constant as the ‘Self Number-Archetype’
7. 11. Book 3 – Calculation of the exact value of the fine structure constant, alpha
8. Highly charged ions could measure changes in fine-structure constant
9. An exact formula for the Electro Magnetic coupling constant

 

20200511M Santa Cruz, CA: What I found interesting about this animation of the last solar eclipse (on Dec. 26, 2019) is how the shadow of the moon onto the Earth changes shape looks similar to how various things look in the real world, such as the shape of a water drop. This analogy helps me visualize our 3-D classical world as a “shadow” of a multi-dimensional quantum world.
