Parallels between the spread of writing and history of technology and ideas

Blueprints and Borrowed Letters - Guns, Germs, and Steel pp 224

The spread of writing has occurred by either of two contrasting methods, which find parallels throughout the history of technology and ideas.  Someone invents something and puts it to use.  How doe you , another would-be user, then design something similar for your own use, knowing that other people have already got their own model built and working?

Such transmission of inventions assumes a whole spectrum of forms.  At the one end lies "blueprint copying," when you copy or modify an available detailed blueprint.  At the opposite end lies "idea diffusion," when you receive little more than the basic idea and have to reinvent the details.  Knowing that it can be done stimulates you to try to do it yourself, but the eventual specific solution may or may not resemble that of the first inventor.

Where do electric cars fit into to this spectrum?  Is the Volt the original electric car and did Tesla fall closer towards "blueprint copying" or was it "idea diffusion?" I believe Tesla closer to idea diffusion.  Their take on the electric car seems more ground up and result of the understanding that the feasibility of the electric car was a viable enterprise.

Highlights from Elon Musk interview with Lex Fridman

#252 – Elon Musk: SpaceX, Mars, Tesla Autopilot, Self-Driving, Robotics, and AI Very interesting interview of Elon Musk by Lex.  Elon's statements about supply chain and manufacturing are very insightful. Here are some of the quotes. "Physics is a law and everything else is a recommendation - lots of people can break laws but nothing can break the physics" (except for the creatures in The Expanse who can change the mass of electrons and the speed of light). First-principles analysis can be applied to any aspect of life.  Let's boil things down to the first principles then things that we are confident are true at a foundational level and that sets an axiomatic base and then you reason up from there. and then you cross-check your conclusion against the axiomatic truth. Some basics of physics you need to check if you violated could be conservation of energy or momentum... Another good physics thing is thinking about things in the limit.  If you take a particular thing an...

Cypress Half Marathon November 09 2025

I ran the Cypress Half Marathon on Sunday November 09 2025.  Stayed the night at Mom and Dad's house.  While training for this event I was running on October 16 and I tripped and sprained my ankle.  It was the worst sprain I can remember.  I did not run for nearly a week after this as I as nursed the ankle in an ice bucket and took ibuprofen to help with the swelling and pain.  That really impacted my training as I could not start training until after I came back from Norway on September 17th which was 7 weeks out from the date of the race. Also I had signed up to run the Sugarland half on Sunday October 12, 2025 but we had planned to visit Saagar for his birthday so we were out in SFO for that weekend.  It was probably for the best as that would have been only 4 weeks to train.  I was able to do the Marina run club with Saagar and get a 6 mile run in that weekend.  After coming back that week I was expecting to train hard straight up to the ...

Ramesh Pateder June 1, 1941 (kind of 10/14/1942) - May 5, 2026

Ramesh "Ray" Pateder June 1, 1941 – May 5, 2026 Kunjarao, Gujarat, India • Cypress, Texas Ramesh "Ray" Pateder, 84, of Cypress, Texas, passed away peacefully at home on May 5, 2026, surrounded by his loving family. He lived a life defined by courage, curiosity, and an unshakable belief in what was possible. https://hhhcrewchief.github.io/RameshPateder/#1 Born and raised in the small village of Kunjarao, Gujarat, India, Ray came of age with dreams that reached well beyond what the world around him offered. In 1962, with a suit on his back and a garland of flowers around his neck, he boarded a plane for the United States — leaving everything familiar to begin his studies in Rolla, Missouri. The journey from rural India to the American Midwest might as well have been a journey to another planet, but he embraced every part of it. Ray's professional career began in Cleveland, Ohio, with Sherwin-Williams, where he refined the technical expertise that would define...
