Steve, In a way, I have higher regard for MAGA people than NIMBYs. At least the build-a-wall people actually have a wall that must be recognized as such.

By coincidence I was listening (with one ear) to Bill Nye (da Science Guy) give his popular hip-hip-hooray for the latest DOE announcement as I read your post here. He nailed *ME* with the perfect alternative descriptor to NIMBY (not in my back yard) with BANANA (build absolutely nothing anywhere anything). I believe it is inevitable that under our current self-conception (all humanity,not just US or the Western Nations) it is virtually impossible to imagine us doing anything but driving technology forward (roughly) as fast as possible, as if to outrun the consequences of our previous actions (and out-compete our competitors with similar levels of capability). Singularity much? Evolutionary Biology coined the Red Queen Hypothesis<https://en.wikipedia.org/wiki/Red_Queen_hypothesis> to describe the latter but I think of it more as (also) a corollary to the prisoner's *dilemma*. This Medium article<https://medium.com/thinking-is-hard/a-prisoners-dilemma-cheat-sheet-4d85fe289d87#:~:text=When%20you're%20playing%20against,also%20defending%20against%20Always%20Defectors.> is a nice pop-sci summary of Prisoner's Dilemma strategies, covering *especially* multiplayer games which I think our various tech/arms races are implicitly. The conclusion of the article, author Benson makes the astute obvservation: The most interesting thing is that cooperation has evolved, even if it feels impossibly complicated and always on the verge of tipping over into fake cooperation (mimicry) and probing (extortion). And as always, when discussing iterated prisoner's dilemma, Nick, et al's MOTH<https://backspaces.net/28/moth-my-way-or-the-highway/> must be referenced.

Rockets are understood, Musk and others can build them. Decades of investment to do something like this is, it is just different. And they were not timid about mentioning the defense side. Concurrent with the test of a U.S. hypersonic too. https://www.defensenews.com/air/2022/12/12/air-force-conducts-first-operational-launch-of-arrw-hypersonic-missile/ On Dec 13, 2022, at 10:16 AM, Steve Smith <sasm...@swcp.com><mailto:sasm...@swcp.com> wrote: Great synopsis... thanks. I'm fascinated at how long we've been "on the cusp" of "lighting up" a micro-star in the laboratory. My first awareness was in the early 70s when a Radio Engineer I worked with had just come from the early MFE Livermore efforts to my tiny hometown AM RAdio station... He described what they were up to as I was taking my first physics course (Junior in HS)... and thinking about the implications both for science (as little I knew it) and society (cheap/ubiquitous energy). Working at LANL for 3 decades (starting with the high energy Proton Storage Ring) put me close to lots of this as an "educated layman". I can't say "nothing's changed" but it is mind boggling how long one can "hang on the cusp" of something. Or how quickly we can go from burning coal to make steam to drive mechanical devices to replace animal and human (and water and wind) labor to lighting up tiny stars for the same purpose. - Steve "some days just drag on, but the years they just fly by" Awesome. Thanks. I'm still trying to catch up with the QC Wormhole kerfuffle. Who knew Quanta was so click baity? What is "DT"?

Timing precision of 25e-12 secs and laser spatial precision of 5e-12 meter were needed. This was thought to be the main explanation for the achievement. 2. 8% more power on the laser this time 3. x-ray tomography is used to find flaws in the capsules. Developing software to do the counting. 4. They have ongoing efforts to study the fabrication systems and their components (done in Germany) to find idiosyncrasies of each. 5. Laser technology improvements since NIF was built which are 20% more efficient. 6. Target cost is from labor, and it takes 7 months each 7. 4% of DT is burned in a shot 8. Machine learning ties together radiation hydrodynamics and experimental data. (It sounded preliminary.) 9. The (successful) capsule had more defects than previous experiments. However, previous experiments did show benefits from capsule quality. 10. 15% of experiments are indirect drive of this kind, 15% of experiments are other approaches to ignition. The rest are weapons and materials characterization. 11. Anomalous laser directional control were problems in the summer runs.
