Here is an explanation by Peter Skands of CERN about the work we do at vLHC@home (former Test4Theory@home):

We run comparisons not only with LHC data, but also with data from many past colliders, such as the Large Electron Positron Collider (LEP) and the Super Proton Synchrotron (SPS) that preceded the LHC at CERN, Fermilab's Tevatron collider, and SLAC's SLD experiment. By doing that, we not only get a sense of how well the generators compare to the LHC data (our main present goal), but also whether and how well they describe the scaling with collider energy, and between electron-positron and proton-(anti)proton beam types. These tests are definitely useful for the efforts to plan future colliders, such as the International Linear Collider (ILC) and the Future Circular Collider (FCC), as well as a possible muon collider, the Compact Linear Collider (CLIC) and other studies now being undertaken around the globe.

I know that fuzzy logic is used in my Yashica camera to focus on the subject. It works well except in the case of fog, which defies even fuzzy logic.

Many years ago, after a very personal experience, I was hit by the idea that our brain is a macroscopic quantum object. Of course I did not tell anybody about this idea but when I read a book by Roger Penrose, "The emperor's new mind" I was bold enough to send him a text I had written in 1980 just for myself which summarized my ideas. He answered me in a week with a very kind letter and suggested me to read his new book "Shadows of the mind", developing the same ideas.
I suggest that you read those books and also one very close to the ideas of Penrose and mine, "Disturbing the universe", by Freeman J.Dyson, one of the fathers of quantum electrodynamics. The books speaks of his companionship with Richard Feynman, who developed a new approach to quantum mechanics and suggested the possibility of building a quantum computer, an idea also treated by Penrose.
Quantum mechanics is based on the idea of probability, and this is why Einstein refused it. But probability implies the existence of a mind, especially in the subjective approach by Bruno de Finetti, a great mathematician.
So quantum mechanics is still an open subject and we haven't exploited all its possibilities.

I usually get my data from NOAA. Here is what it says about the Sun today:
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
25/0702Z from Region 2121 (N08E30). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one and two (26 Jul, 27 Jul)
and likely to be low with a slight chance for an M-class flare on day
three (28 Jul).

IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
387 km/s at 25/1501Z. Total IMF reached 6 nT at 25/1259Z. The maximum
southward component of Bz reached -6 nT at 25/0612Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (26 Jul), quiet levels on
day two (27 Jul) and quiet to active levels on day three (28 Jul).

Sorry don't buy any of those three supposed explanations. Faster than light eh? OK .... The point here is that everyone refers to it as "Quantum Theory" and that is what it is. Nothing has been proved, it is a theory.

No, the Bell inequalities have been proven by Alain Aspect in experiments.

I think that the Sun is entering a quiet period with few sunspots. The Maunder Minimum was corresponding to a Little Glacial Age.

When physicists can't resolve a problem they ask for a new machine, be it a cyclotron, a synchrocyclotron, a storage ring or a collider. But when the new machine is built it opens so many new problems that the problem to resolve which it was built is forgotten. Then they ask for more machines to resolve the new problems and so on. This was called "The spiral of high energy" by Italian physicists Angelo Baracca and Silvio Bergia in 1975 and it still applies.
Nobel prize winner Emilio Segre', whom I personally knew while publishing a book of his, "Personaggi e scoperte nella fisica contemporanea" had expressed the same ideas in a 1972 article on "Endeavour" magazine.
In my opinion particle accelerators are similar to Egyptian pyramids. You build a e bigger one to demonstrate your power and so it may be that the new machine could be built in China. But the International Linear Collider, to be built in Japan, is a strong competitor.

Il Tour e' arrivato a Bergerac, patria credo di Cyrano, che nessuno ha nominato nelle varie trasmissioni. La tappa e' stata vinta dall'estone Ramunes Navardauskas dopo una brutta caduta sul bagnato negli ultimi tre km da parte di vari corridori, per cui i ritardi sono stati neutralizzati e la classifica e' la stessa.
Ieri una gentile fanciulla che si faceva un selfie con le spalle alla corsa per poco non faceva cadere un Nibali lanciato verso la vittoria. Oggi si e' scusata con lo stesso telefonino. Domani cronometro di 54 km, che stabilira' chi va sul podio fra tre francesi e Alejandro Valverde.Speriamo niente selfie!

Nibali ha vinto a Hautacam nei Pirenei staccando in salita tutti i suoi avversari e dimostrando di essere il vero Patron del Tour. Secondo in classifica e' adesso il giovane francese Thibaut Pinot, terzo Jean Christophe Peraud, quarto Alejandro Valverde e quinto un altro giovane francese, Romain Bardet.
Nelle prime due tappe pirenaiche Nibali si era difeso anche a causa della stanchezza dellla sua squadra che deve proteggere ogni giorno la maglia gialla. Oggi ha stracciato tutti ed entra nella styoria del Tour come Gimondi e Pantani.
Domani pianura, sabato una crono di 54 km, domenica la passerella fino a Parigi.
Chapeau, Vincenzo!

That is why I said that the problems of tokamaks are not plasma physics problems but engineering problems. Radioactivity is a problem of all reactors, fusion or fission, that is why I believe we should recur to the Sun. A photovoltaic panel may be costly and ungainly but it is not radioactive.

Since its beginning, fusion reactions as a energy source have had many approaches (including cold fusion), but now 2 only remain: tokamaks and inertial fusion by lasers, such as tested at Livermore also for military purposes. The Lockheed-Martin machine is a small size tokamak; the Focus Fusion, while interesting, is shown as it was in 2007. None of the two videos mentions the Lawson criterion, that is the product of plasma density, plasma temperature and plasma confinement time. This is the essential parameter of any fusion machine.

I didn't know that Lockheed-Martin, a builder of warplanes like F35, had any research on fusion. The man said his machine would be a high beta experiment but made no reference to ALCATOR of Bruno Coppi. ALCATOR stand for ALto CAmpu TORus (High Field Torus). He made no mention of Tokamaks smaller in size than ITER or of other approaches such a Stellarator. Anyway, let them try. Watch and see.
I never heard of Focus Fusion. The only thing I understood was they intend to use the DT-Boron reaction to obtain directly electricity without the need of a thermal interface. Well, let them try too.

Tullio you reakon the downing of the plane will effect the project now ? Maybe your gov will pull out now ? Is it based or the ITER reactor a plasma or they going a different way with this 1

I hope not. Russia is not to be accounted for the Ukraine tragedy. Some Ukrainians are guilty, probably of the pro-Russia faction. It is easy to cause a tragedy and then accuse your enemies for it. I believe in science and not in wars.
The IGNITOR project is the brain child of Bruno Coppi, a scientist I met in Trieste at the I.C.T.P "Abdus Salam" in 1969. I believe in his honesty and the Russians seem to have appreciated him. The ITER project is a son of many fathers and you certainly know the definition of a camel as a horse designed by a committee. I think research on fusion should go on but the price of ITER is not right , as "Nature" magazine has said.
Tullio
IGNITOR is basically a TOKAMAK, like ITER. TOKAMAK stands for Toroidal Kamera Magnetika and the idea is due to Igor Kurchatov, to which the Institute where IGNITOR sould be built is named.
