A map of the Internet from 1969

A map of the Internet from 1969. Some thoughts on the 10X coder. “Braitenberg’s Law” notes that it’s easy to understand a complex robot or piece of code if you wrote it; if someone else did, it’s insanely hard. “Taking turns is a primary expression of justice”: An essay on the moral dimensions of phys ed, from 1922. Meet the Girl Scouts who are earning cybersecurity badges. Why Grenfell Tower burned. My favorite piece of 19th-century punctuation is the “colash”, a colon followed by a m-dash, like this … “:—”. My New York Times Magazine feature on computational thinking and “The Minecraft Generation” from a year ago; and a podcast with me talking about it.


“Genius hesitates”

I read Carlo Rovelli’s book Seven Brief Lessons on Physics, a layperson’s description of the big breakthroughs in modern physics. It’s a blast, but one throwaway comment really struck me.

Rovelli is discussing Einstein’s 1900 paper about photons and light. He quotes what Einstein wrote …

It seems to me that the observations associated with blackbody radiation, flourescence, the production of cathode rays by ultraviolet light, and other related phenomena connected with the emission or transformation of light are more readily understood if one assumes that the energy of light is discontinuously distributed in space.

Then Rovelli makes a nifty point …

These simple and clear lines are the real birth certificate of quantum theory. Note the wonderful initial “It seems to me …,” which recalls the “I think … ” with which Darwin introduces in his notebooks the great idea of that species evolve, or the “hesistation” spoken of by Farraday when introducing to the first time the revolutionary idea of magnetic fields. Genius hesitates.

Genius hesitates. I love that! When we approach a truly enormous idea, of the sort that tilts the world on its axis, we’re not excited and arrogant and confident. We’re unsure; we hesitate. I’ve noticed this in the scientists I interview. The ones who are doing really groundbreaking work are tentative, cautious, almost unsettled by the implications of what they’re saying.

It’s not a bad litmus test for the people around us in everyday life. The ones who are proposing genuinely startling and creative ideas are liable to be … careful about it. It’s the ones with small ideas who are shouting them from the rooftops.

By the way, that notebook of Darwin that Rovelli mentions? It’s online, and here’s the page he talks about. You can see Darwin scribble “I THINK” at the top …
