Je viens de voir "B-Girl Sissy", la jeune femme qui représentera la France aux JO 2024 dans la discipline break-dance-hiphop.
Bha comme mon copain handi-triathlète palois, pour lui, pour elle, j'ai envie que ces JO ne soient pas sabordés.
Là de suite j'aimerai que B-Girl Sissy utilise Silmarils ou FFF pendant les JO.
FFF, Barbès !

After an August break (in the best Iberian tradition), the latest transmission for Music For Dreams is here. With a couple of exceptions it's a look back at some of my favourite tunes & releases from the summer from Wurlitzer improvisations, melancholic cosmic folk to ambient relaxants and dreamy electronica.
This style of art is my attempt to stand out from all the other fractal artists out there. Prints are available at the link.

The sun is now approaching its maximum level of activity in the current cycle, and it’s not exactly behaving according to plan.

@martinrsmith #horizon Hidden amongst all the joy of belatedly rejoining as an "associate" of a science collaboration we should never have left in the first place #BrexitDisaster is the news that we shall no longer be part of the #Euratom programme. Access to #fusion energy research is shortly to become a patent nightmare for the Brits
BTW "associate" means it will be nearly impossible to get a grant for anything remotely British lead

As I've posted that #CaptainDisillusion video, here's a little secret: I made a paintout video tutorial for #Fusion years ago (11 years according to youtube 🙀 ). It was so much more work than I expected due to white-balancing so I actually had to solve that problem as well. And there were Fusion bugs I needed to work around.
We are excited to announce the Next Big Thing Contest! Are you passionate about creating software features that enhance the lives of people who are blind or low vision? Help shape the future of JAWS, ZoomText, or Fusion! Check out this introduction video: https://youtu.be/j32Zwv7L8hw?si=k8TlmxdfFEhT1LT4
Remember Shakti - Live at the Arlene Schnitzer Concert Hall, Sept. 2003 - FLAC and MP3 downloads
A very beautiful, extremely clean audience recording made from the 8th row by a friend. The drum sound is particularly realistic I think.
Lineup for this tour was:
John McLaughlin - guitar, macbook pro
Zakir Hussein - tablas
U. Srinivas - Carnatic mandolin
V. Selvaganesh - kanjira, ghatam, mridangam
Weather Report - Heavy Weather
I first heard this in high school, probably the first jazz-fusion album I ever bought, and my introduction to Weather Report and the distinctive bass playing of Jaco Pastorious...to say nothing of Wayne Shorter, Joe Zawinul and the rest.
It's held up remarkably well...
Saw the Shakti 50th anniversary tour show at Wolf Trap last night.
Wow,what a treat. An amazing display of virtuosity.
Probably one of the best performances I have seen this year.
John McLaughlin Zakir Hussain , Shankar Mahadevan, violinist Ganesh Rajagopalan and percussionist Selvaganesh Vinayakram.

Scientists produce second major breakthrough in nuclear #fusion, once again generating more #energy than they put in. WOW. This means I officially lived to see it. #climatechange #climatecrisis #globalwarming #BanFossilAds #fossilfuels #ExxonKnew #suethebastards
Imagine seeing fusion power on this graph someday. (This is the California power grid right now.)

IO - A Track from the new The Fusion Syndicate album, A Speedway On Saturn’s Rings, which is to be released September 1, 2023. Rick Wakeman has teamed up with former PiL bassist Jah Wobble and former Frank Zappa, Weather Report and Genesis drummer Chester Thompson for a powerhouse of a track driven by a forceful Wakeman keyboard solo.
Replicability is a key factor in getting to understanding fusion and getting to a point where we get abundant energy.
A barrage of X-rays hit a tiny pellet at temperatures and pressures greater than our sun's.
Scientists repeat nuclear fusion breakthrough in a step toward more clean energy.
Smithsonian Magazine reports: "Nuclear scientists say this is a key step toward producing clean and potentially cheap power — though they warn the fledgling form of energy still has a long way to go before it becomes a viable option."

NEW TODAY - another Neurographic piece
@gadgetboy Thanks to (the somewhat problematic) #SabineHossenfelder on #YouTube, I know these headlines are extremely misleading, at best, ignoring the full amount of #energy used to power the #fusion, which makes these "advances" purely theoretical, using a net negative amount of energy.
"Energy gain in this context only compares the energy generated to the energy in the lasers, not to the total amount of energy pulled off the grid to power the system, which is much higher."

From 07 Aug: Physicists achieve fusion with net energy gain for second time - Enlarge / Researchers at the Lawrence Livermore National Laboratory in California have use... https://arstechnica.com/science/2023/08/physicists-achieve-fusion-net-energy-gain-for-second-time/ #fusion #science #syndication
While I’m a huge fan of #fusion and firmly believe it’s an important part of our future, this is a tiny, incremental improvement. While the energy output is higher than the input, it’s still a fraction of the energy required to charge the lasers that deliver the input.
Technically, this may be due to inefficiencies in energy transmission & storage, but that is the world we currently live in.
"Ideally, the lasers would be able to fire several times a second. NIF currently fires its lasers just several times a year, ..."
"And currently, NIF’s lasers are so powerful that they damage their own guiding optics every time they fire."
So, there remain some engineering problems to be solved 😜
Cautiously optimistic about all the scientific breakthroughs that feel like.. MAYBE they could be in the realm of possibility after all? 🤞😖🤞
#NuclearFusion #LawrenceLivermore #Fusion #EnergyScience
In a repeat of the expt. from Dec 2022, the fusion facility at Lawrence Livermore achieved a net energy gain for a few nanosecs.
2.05 MJ -> 3.5 MJ (was 3.15 MJ in 2022)
But, energy to drive lasers = 300 MJ 🙁
1 MJ = 0.27 kwh
UV lasers are used to heat H isotypes (deuterium and tritium), causing fusion and energy release as neutrons.
However, it is still a long way from a nanosec experiment to powering the grid.
Good news this morning.
Lawrence Livermore National Laboratory scientists have *repeated* their “more energy out than energy in” #fusion experiment a year after their initial breakthrough.
A promising advance but still a long way to go.

#AudioMo: Today it's a musical selection from a gig I played a few years ago as part of a #Jazz #Fusion #Quartet called Nuvorrian. We had headphone boxes for each musician as we were playing on an outdoor stage, so I took a patch-cable from the headphone box to my recorder and captured it that way.

Euch ist schon klar, dass viele von Euch Politikern das nicht mehr erleben werden? Ihr wisst schon, dass das noch dauert, das kann eigentlich nur eine Nebelkerze sein um die Energiewende zu sabotieren.
I would like to inquire about some weird and potentially dubious claims of net energy producing nuclear fusion.
Some hype is going around an entity called Helion. I'm having trouble finding a good description of what exactly it is that they're hyping. All the sources that I have so far are full of red flags of the "this was written by a low-clue PR person" kind. This is often a sign of Theranos-like affair, but considering the high likelihood of such a distortionary process, the things that do seem like physics-side red flags might plausibly be just mistakes by the PR person, so I'm also not, at least so far, confident that it is a grift.
If you happen to understand what it is that Helion claims to do, or better yet, have a link to a good description, please share.
