What fusion produces are 14 MeV neutrons. Having worked with neutrons in my youth, I know they are bad beasts. They can destroy any material in a short time. So the "first wall" in a fusion reactor shall have to be substituted in a short time. But of course it will be radioactive, so the substitution shall have to be made by robots,not by human beings. So engineering problems in a fusion reactors will be huge, even when plasma physics problems are solved. Good luck.

Kepler is still working, although in a lesser mode.

The Lick Observatory, where Claire Max developed her laser method, has received a 1 million $ donation from Google, according to Berkeley Online News. Claire Max is the interim director of all University of California Observatories.

Collision events in LHC are simulated on my computers using the CERN programs vLHC@home and Atlas@home, which require the installation of Virtual Box by Oracle. LHC@home instead checks the stability of particle orbits in the LHC.
The program MCPLOTS gives the number of events simulated by my 3 computers, of which 2 use Linux and one Windows 8.1. I have simulated so far about 879 million events and I am approaching 1 billion events, after which I shall be admitted to the Billionaire club.

Ieri sera ho visto una tedesca vincere il salto dal trampolino davanti a una giapponese e una austriaca. Ma mi chiedo se la pista di discesa del trampolino, rifatto nuovo per questi campionati, fosse di neve o di plastica. A me pareva di plastica.

The ITER project in France is an international project. It has so far cost 15 billion dollars and is going to cost another 10 billions without producing a single watt of power. It is just a "proof of concept" experiment in plasma confinement according to the Tokamak line of design. Another experiment, of much lesser cost, is being built in Moscow by an Italian-Russian cooperative effort. It should cost 250 million dollars. It is a design along the ALCATOR machine built at MIT by Bruno Coppi and is called IGNITOR.

Not only. There was a nuclear reactor in Africa, not made by men , but by Nature.

Uranium exists in nature. It is a mixture of three isotopes, U238,U235 and U233. Only U235 is fissile, the others two are fertile. Plutonium is created artificially in nuclear reactors or Cyclotrons. But all this is an old story,

Quantum physics has nothing to do with nuclear weapons. The basic principles of nuclear weapons were established by the scientists of the Manhattan project and haven't changed. Then Edward Teller and Stan Ulam on one side of the Iron Curtain, Andrej Saharov and others on the other side developed the hydrogen bomb.Read the book "Disturbing the Universe" by Freeman J. Dyson for an overview of this story. Dyson tells the story of a student who gained enough information in the building a nuclear weapon from free sources without breaking any law. There is no secret in it, you must only enrich uranium or produce plutonium in a nuclear reactor. This is just engineering.

Quantum physics cannot harm anyone. It is not a weapon of mass destruction, it is only difficult to understand. But perhaps it manages our minds, as Roger Penrose thinks,and I tend to agree with him.

I think we are more in danger from global warming that from nuclear weapons. But the real danger is if a terrorist group gets its hand on an atomic warhead. I've read that Americans are afraid that some nuclear warheads in an Italian air base aren't watched properly.

We had this danger at the time of the Cuba crisis in 1961. But Kennedy and Kruscev avoided it, with the help of Pope Giovanni XXIII.

CERN has built a number of particle accelerators of greater energy, learning from every step. The head of the Italian project of a hadron accelerator for cancer therapy is Ugo Amaldi, son of Edoardo Amaldi, one of the founders of CERN. Basic research often gives results used in medical therapy and also industry. One example is Computerized Tomography, which uses software developed by astronomers to get images of celestial radio sources. In turn, they used an algorithm developed by a Russian mathematician with no application in mind. Another example is Magnetic Resonance scans (I took two of them recently).
Also, the transistor which we use every day, derives from basic research in solid state physics. So, it would be a mistake to stop basic research and the Americans regret the decision to abandon the Super Conducting Super Collider, which was to be built in Texas.
Year 2015 has been proclaimed the Year of Light by the United Nations General Assembly. I've read on "Nature" magazine of advances made to use common light to explore biological materials, such as living tissue. This would decrease the danger of using X-rays and strong magnetic fields such as CT and NMR, which recently broke my remaining teeth in the upper part of the mouth. So long live basic science!

I found Windows 8 installed in the PC and it was updated soon to 8.1, but I have no DVD wit the OS. I was allowed to make a Recovery Image on 4 DVD when the OS was still 8, but I was not allowed to make another when the system was 8.1. There is a Recovery Image on the hard disk.
My files (not the OS) are copied daily on a Toshiba external disk connected via USB. On the whole I am satisfied with Windows 8.1 and am using it on several BOINC projects,

Norway has also good alpine skiers like Svindal and Jansrud. Sweden had the great Stenmark and now has good female skiers. But the Wurld Cup this year is restricted to Tina Maze and Anna Fenninger, probably the best skier.

Particles accelerators are used to treat tumors that are not cured by surgery. There is a hadron therapy accelerator in Pavia and my daughter was writing software for it in her thesis.Then a minister did not give any money to the University of Milano and she had to find employment in a software house. But I have published articles in the Seventies on the Mondadori Yearbook which described this use of accelerators, and I was happy to see my daughter working on it.

Also, the X-rays produced by the Elettra Synchrotron Light Source in Trieste, built by Carlo Rubbia, are used for diagnosis of breast cancer in women.

I am an absolute Windows beginner, so I install all the updates that Microsoft sends to my 8.1 OS. So far no problems, even if I have on it two projects using Virtual Machines (Atlas@home and vLHC@home) and two projects using a graphic board, Einstein@home and SETI@home. I did not install any new driver and I am using what was installed on this Hp Pavilion 500-152ea when I received it.

I was taught Telemark but never really mastered it. I just saw a Norwegian girl win the first sprint. The second is a Swede, the third another Norwegian.
Men: 1 Norway, 2 Canada, 3 Norway.
Federico Pellegrino is fifth in classic skiing. He prefers free skiing.
