However, there is no chance of new discoveries until the accelerator reaches at least 3.5 tera electron volts, half of its planned maximum power
The Axis Particle Accelerator, or the Large Hadron Collider is already officially the most powerful particle accelerator ever operated. On Monday morning, he broke a record for the acceleration and collision of protons with an intensity of 1.18 tera-electron volts, thus crossing the previous record - 0.98 tera-electron-volts at Fermi Laboratories near Chicago. The American accelerator has been operating at this power since 2001. Until yesterday evening, the accelerator was operated at a power of 0.45 tera electron volts.
The success, recorded right in the wee hours of the morning, is a continuation of preparations to reach even higher levels of energy in collisions next year, with the aim of understanding the nature of matter in the universe. In the last two weeks, the scientists operated the accelerator at increasing intensities, ran the protons in both directions and also performed several collisions at low intensities to test the reaction of the equipment used by the accelerator and the four experiments along the 27-kilometer tunnel.
As you may recall, the particle accelerator was shut down about a year ago shortly after its opening in October 2008, due to a collapse of the system that cools the magnets that direct the beams in the circular tunnel to a temperature of 2 degrees above absolute zero. The CEO of CERN, Rolf Hoyer said that the activation so far has been successful and that in any case, the preparations will continue step by step. "There is still a lot of work until we start seeing new results in physics in 2010," Hoyer wrote in a press release. He added that he keeps the bottles of champagne frozen until then.
The scientists predict that it will be possible to notice new phenomena when the power of the facility reaches 3.5 teraelectron volts in the middle of 2010.

A simple Jew, is the random use of bombastic words some of which have no meaning intended to make you a complex Jew?
Shrek talk of "wise men in their own eyes"
Stop talking high and high, and start thinking and trying to understand who created such a wonderful and amazing world and enough with the platitudes and singularities and organic formal Platonicism and this will not help silence the terrible feeling that requires an explanation and demands insights about our conduct in the world.
What does a proton collision produce at such a level? What particles?
Ramnoges
I will answer you instead of Moshe
who chose not to continue the discussion
Neither platonic nor formal, but an organic concept
If you contact Moshe through his site Gan Adam
He will probably answer you
Moshe Klein:
A question for you please.
Is your mathematical conception predominantly Platonist or formalist?
Michael, I'm done participating in the discussions here.
I joined mainly because of the article on Ramanujan
You can correspond by email or meet, as you wish.
Successfully !
Moses
Moshe Klein:
Unfortunately I don't even begin to understand what you are saying.
One point, I didn't understand what you're saying, are you saying black black will swallow us up in 2012? Wow really scary!!
This is a point. I withdraw from the discussions.
I have one last question for you:
What does the line consist of?
What to do, the money goes to the laboratories. The cheapest investment is in philosophy:
Physicists need very expensive laboratories, pens, sheets, and garbage cans to throw away the wrong results.
Mathematicians require pens, sheets, and trash cans to dispose of their mistakes.
The philosophers, for their part, require only pens and pages.
Michael,
The Louis and the mathematicians were able to raise a tenth of the 10 billion dollars to build the accelerator.
I'm guessing they won't discover the Higgs particle and even if they do, it won't close the loopholes
which exists today in the perception of the particles of matter. You understand that a revolution in physics is not made every 100 years.
Enough with relativity and quantum theory. As for a revolution in mathematics, that's another story.
In Hilbert's sixth problem in 1900, he spoke about an axiomatic foundation of physics. He focused on probability, mechanics and geometry. Regarding mechanics, Einstein has already dealt with... the subject. Do you think Kolmogorov really addressed the deep meaning of probability in quantum theory?
Point, you once again bring up the issue of the hole.. seriously
So please send a suitable reference to the site here.
Did you know that Hilbert published the theory of general relativity
In 1915, a week before Albert Einstein?
Thanks to all who answered me. 🙂
sympathetic:
I didn't write the things to disagree with you.
I know what you did and you did it well.
I just prepared the comment in WORD at the same time as you and uploaded it when I finished copying everything.
Only after I uploaded it did I notice that you also answered.
Michael
7 tera electron volts divided by 1000 MeV
Gives 7000.
Get 7500 from a calculation using the exact mass 938 MeV
I gave a thumbs up.
Regarding the Lorenz constant I gave an estimate again
A more accurate calculation gives a Lorentz constant of 7500 to the minus power
2 gives approximately one divided by fifty million the result must be divided by two
(since the speed of the proton is almost equal to the speed of light) and it is obtained that
The difference between the speed of light and the speed of the proton is about 10 to the minus power
eight times the speed of light
In the description of LHC in Wikipedia:
http://en.wikipedia.org/wiki/LHC
Write:
At this energy the protons have a Lorentz factor of about 7,500 and move at about 99.9999991% of the speed of light
The Lorentz constant is the number by which the rest mass must be multiplied to get the relative mass.
The rest mass of a proton is about 1000 MeV, which means 10 in nine electron volts.
Thus the mass ratio is 7000, since the mass ratio is given by a root of one
Minus the square of the speed divided by the speed of light, we get that the speed of the proton is
The speed of light up to (-8)^ 10*4
That is 0.99999996 of the speed of light
Moshe Klein, what I said about the earth being destroyed by a black hole that will swallow it, is not a prophecy at all. This is a simulation of supercomputers that show that this is what is going to happen.
It is not relevant if Yehuda understood what you wrote in the first response, my words were said regarding your response 4.
Moshe and Yehuda:
I imagined that this was the intention and in fact I even answered it.
The expression "exists freely in nature" has no meaning.
When all the uranium is known, would it be correct to say that there is no uranium even though it can be regenerated?
In fact, most of the particles found in accelerators so far - were only found in them.
This is because their lifespan is very short.
Do any of you want to argue that they might not exist?
The same is true for unstable foundations.
If it is assumed that the laws of nature are fixed (and there is no meaning to scientific research without this assumption because the laws of nature are what this research is trying to discover) then collisions in the accelerator will produce the same results as collisions outside the accelerator.
The only difference is that in the accelerator we can observe the results and outside the accelerator we cannot.
If you read my previous (short) answer again - you will see that this is what I said in it as well.
And one more thing for Moshe:
Point's words about the black hole were a joke.
I think you found that out at the time.
I don't think you're trying to joke.
You can doubt what you want - this is not a great wisdom and many people are only concerned with this.
Once you offer something more productive it might be worth talking about.
Just to get an order of magnitude.
Does anyone know what percentage of the speed of light a proton reaches with an energy of 7 tera electron volts? And what is its mass at such a speed relative to the rest mass?
point. If prophecy was given to fools
So why did you write here that the earth
will pass through a black hole in 2012
The batter I wrote here
gently casts doubt, in mathematical language
For the scientific meaning of the particle accelerator
Thanks Yehuda!
You managed to explain my thought
Much better than me
I understood Klein in his first response as follows:-
Let's say we find a new particle in an experiment in the sun, so where do we have the assurance that it will also be found free in nature?
Maybe he is just a product of an experiment?
Good Day
Sabdarmish Yehuda
Moshe,
The prophecy was given to fools. How do you know that the universe is a one-time singular case? Maybe use a little self-criticism and skepticism before you throw fictions into the air.
Apart from that, it is not clear what you are trying to say in the mixture of things that you write and which seem to me to be unrelated to each other.
Einstein's theory of relativity is related to Gauss and Riemann. Why did you bring Hilbert?
The evidence that the next development of mathematics will come from the direction of physics are these cosmological or quantum observations?
Michael
In my opinion, a major problem that exists in science today is that on the one hand it strives to reach natural laws and generalizations, but on the other hand it is impossible to ignore that the entire universe is a one-time singular case!
I hope the accelerator will work at full power and discover the Higgs God particle but..
Quantum theory brought two new principles to science. The principle of superposition and the principle of measurement. According to the principle of superposition each particle, for example the electron, can be in several places at the same time. According to the principle of measurement, the measurement of the particle creates a collapse of the wave function to obtain one specific value from a variety of possibilities of the measurement results. With the help of these two principles, quantum algorithms were also developed, such as Shor's algorithms for the decomposition of numbers.
In his lecture in Paris in 1900, David Hilbert defined the sixth problem in the famous list of 23 problems as the development of new tools for the axiomatic establishment of the science of physics (Mathematical treatment of the axioms of physics. Today it seems outdated that Hilbert chose to focus on formulating the problem in geometry in mechanics and probability. A few years after announcing The problem is, physics has changed beyond recognition. The special theory of relativity has fundamentally changed mechanics and an increasing use is made of precisely non-Euclidean geometry to establish the theory of general relativity. The theory of probability was indeed formally formulated by Kolmogorov while ignoring the quantum theory.
But today there is evidence that the next development of mathematics should come precisely from the direction of physics.
Moshe:
What do you think "existing in nature" is?
I hope you don't think that the accelerator changes the laws of nature and therefore everything that is created in it exists in nature in the sense that there is a law in nature that says that "when you do such and such you get such and such particles with such and such a probability".
hello my father
I read the update about the particle accelerator in the tail. First of all, I wanted to point out in a passing note that the tradition of the ICM World Mathematics Conferences also began in Switzerland in Zurich in 1897 (the same year as the first Zionist World Congress in Basel). I am happy that the problem has been fixed and the particles are starting to be accelerated there. About two years ago I even heard 2 interesting lectures by Prof. Elam Gross from the Weizmann Institute who works in the project. I am a mathematician and not a physicist, but I understood that the goal of the project, among other things, is to discover a particle called the God particle (Higgs) which is currently missing in the particle puzzle. I want to ask Tam a question.
In light of the principles of quantum theory on the principle effect of the measurement on the results of the measurement,
Do the particles that will be discovered there really exist in nature or are they the result of the accelerator experiment?
