Tevatron Explained: Emmy Noether's Mass Page

  • Thread starter wolram
  • Start date
In summary, the Emmy Noether site discusses how mass can be explained by how photons are slowed down in a solid medium. The site also discusses how the higgs field may be without a higgs particle or even a photon field. All events are interactions of fields and subatomic particles are condensates of said fields.

hi, can someone explaine what a tevatron is? i forget who gave me this link i think the page on mass is excelent.

wolram,
the Emmy Noether site is a lovely one. Always a pleasure to
return to. This time was special because of the page on mass, which I had not seen before! Thanks.

It describes how distortion in the crystal lattice around a photon can slow it down and give it an appearance of mass (as long as it is propagating in the solid.) Reminiscent of the imagery in those UK essays----M.Thatcher proceeding thru a crowd etc.

Higgs may have thought up his field by analogy with what they describe here happening with light in a solid medium.

TEVATRON

You know the eevee measure of energy (1.6E-19 joules) the amount of energy an electron gets from a one-volt battery.

When they had accelerators that could give a particle a billion eevee of energy they called them "Bevatrons"
Bev meant billion electron volts.
Now it is fashionable to say Gev (for giga-) instead of Bev

Tev can mean trillion (E12) electron volts or speaking fractured metric "Tera-eV"

They have an accelerator at Fermilab that can get energies up in the trillion eevee range. So why not call it a Tev-atron?

hi marcus, what is your view on a higgs field without a higgs particle
or even a photon fields without a photon? or even that all events are ineractions of fields and subatomic particles are condensates of said fields, hope you can follow my ranting.

you are asking a very personal question:wink:

about some things it may be better to try to talk the way other people talk and keep one's personal views to oneself

rushing in where angels fear to tread, as usual, I really like thinking of the fields as the basic objects of which any theory is built and "photons" as just twangs or excitations of one of the fields

I don't think the world is built up out of this-ons and that-ons like some nifty varieties of marbles.
To speak of "gravitons" is to adopt an approximation of gravity in flat Minkowski space (special rel) that is unrealistic. I don't think of gravity as built up out of "gravitons" in a flat Minkowski space but as dynamic geometry.

But one must immediately say that the approximations are excellent! So perhaps we should always speak in terms of photons! This helps to remind us that the excitations are quantized into little bundles of energy E and angular frequency w where, miraculously, E is always equal to hbar times w.

One more thing. It doesn't ultimately matter too much how I think of things as long as I can calculate predictions that match reality.

So, for example, in natural units the temp at surface of the sun is 40.8E-30. So I multiply by 2.701 and get 110 and I tell you that
the frequency of the average sunlight photon is 110E-30
in Planck units of frequency and the energy of the average sunlight photon is 110E-30 Planck energy units and the angular wavelength of it is (1/110)E30 times the Planck length.
And if you convert these to metric it will turn out that's
compatible with the handbook data---it matches the real world.
(2.701 is a mathematical constant like pi which one uses with Planck's black body radiation law) In that sense, what matters is not how I think about photons but whether the numbers match up.

Now you see I am ranting :smile: and you hardly did at all!

as usual marcus you make sense , i for one canot pescribe to a multitude of "particles all with various properties", that permeate space, if one wants to quantisize everything one has to go to a single origin and that origin can only be energy therefore matter can only be a condensation of energy, or i am nuts, i hate math it can prove or disprove any theory if observation is in unity with the math then it is taken as fact so ,whitch comes first theory or math, think of entanglment, spontanious quark production, why is it that the top quark is the only truly interactive particle that interacts with "gravity" in the strong sence?

i am always learning what i don't know wolram...
 

1. What is the Tevatron?

The Tevatron was a particle accelerator located at Fermi National Accelerator Laboratory (Fermilab) in Illinois, USA. It operated from 1983 to 2011 and was one of the world's largest particle accelerators, colliding protons and antiprotons at high energies.

2. Who is Emmy Noether?

Emmy Noether was a German mathematician who made groundbreaking contributions to theoretical physics, particularly in the areas of abstract algebra and theoretical physics. Her work on the concept of symmetry in physics has had a profound impact on our understanding of the laws of nature, including the conservation of energy and momentum.

3. What is the "Mass Page" in relation to Emmy Noether?

The "Mass Page" refers to a specific paper published by Emmy Noether in 1918 titled "Invariante Variationsprobleme" (Translated: "Invariant Variation Problems"). In this paper, Noether introduced the concept of conserved quantities in physics, which is now known as Noether's theorem.

4. How does Emmy Noether's work relate to the Tevatron?

Emmy Noether's work on symmetry and conservation laws is directly applicable to the Tevatron and other particle accelerators. Noether's theorem states that for every continuous symmetry in a physical system, there is a corresponding conserved quantity. This theorem has been instrumental in the development of modern particle physics and has been used to make predictions and analyze data from particle collisions at the Tevatron.

5. Why is the Tevatron significant in the history of particle physics?

The Tevatron was a pioneering particle accelerator that played a crucial role in many significant discoveries in particle physics. Notable achievements at the Tevatron include the discovery of the top quark in 1995 and the first evidence of the Higgs boson in 2011. Its advancements in technology and techniques also paved the way for the construction of the Large Hadron Collider (LHC) in Europe, which has continued to push the boundaries of our understanding of the universe.
