Freeman John Dyson... R.I.P., the Free Man

15 December 1923 – 28 February 2020

Freeman John Dyson was an English-born American theoretical physicist and mathematician known for his work in quantum electrodynamics, solid-state physics, astronomy and nuclear engineering. He was professor emeritus in the Institute for Advanced Study in Princeton, a member of the Board of Visitors of Ralston College and a member of the Board of Sponsors of the Bulletin of the Atomic Scientists.

Dyson originated several concepts that bear his name, such as Dyson's transform, a fundamental technique in additive number theory, which he developed as part of his proof of Mann's theorem; the Dyson tree, a hypothetical genetically-engineered plant capable of growing in a comet; the Dyson series, a perturbative series where each term is represented by Feynman diagrams; the Dyson sphere, a thought experiment that attempts to explain how a space-faring civilization would meet its energy requirements with a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output; and Dyson's eternal intelligence, a means by which an immortal society of intelligent beings in an open universe could escape the prospect of the heat death of the universe by extending subjective time to infinity while expending only a finite amount of energy.

Dyson believed global warming is caused by increased carbon dioxide through burning fossil fuels but that some of the effects of this are favourable and not taken into account by climate scientists, such as increased agricultural yield. He was skeptical about the simulation models used to predict climate change, arguing that political efforts to reduce causes of climate change distract from other global problems that should take priority.

Dyson died after a fall, at a hospital near Princeton, New Jersey, on 28 February 2020 at age 96.

We should take into account the intermittent nature of wind and solar, as well as the carbon footprint and hazardous materials required for building and decommissioning them after their end of life. Unfortunately these problems makes solar and wind insufficient to tackle #climate-change.

The only viable alternative to #fossil-fuel right now is #nuclear.
yeah. nuclear's much less hazardous with much less carbon footprint to building and decommissioning nuclear than wind turbines.

wind's clearly not viable. scotland must be crazy generating all that energy from wind.

*boik*

That Time the U.S. Air Force Proposed Using Rockets to Stop the Earth's Rotation - The Daily Grail


Here's something I'll bet you didn't know. I recently read about this in a book by Daniel Ellsberg.

Code Name: Project Retro


It's insanely funny. They operative word here is "insane".
