I have had a most interesting Autistic day, as usual! Today, I dutifully attended my appointment for another Tetanus Jab at the splendid Kingston Crescent Health Centre in Portsmouth.
Why? Because, apparently, Tetanus (which I thought is AKA Lockjaw) is the SECOND MOST DANGEROUS GERM in the Human Universe! Portsmouth NHS Trust is determined that everybody receives 5 Tetanus Jabs in their lifetime.
Naturally I asked the Doctor what is the MOST DANGEROUS germ...
"BOTULISM", he told me.
"Well, I certainly have never had THAT!" said I.
"No", he said, "If you had, you would not be here!" 🤣
Curiously they did not add the wretched Covid and coughing 'Flu to the MMR and Tetanus pin-sticking on my right arm.
Apropos Ψ, I would say it is certainly a Wavefunction, but surely it must be relativistically invarient, M. mchambin?
I am thinking Max Born's or Erwin Schrodinger's approach is insufficient.
No. We need a man of Professor Paul Dirac's competence:

In fact, I am frequently struck by mine own resemblance to Paul Dirac. I wonder if we are related? 🙂

That would be a reasonable assumption.
φ represents a "complex order parameter field" which is analogous to a quantum mechanical wave function.
Perturbing the field φ around the ground state φ0 results in oscillations of the amplitude (toward and away from the peak of the hat) and phase ϕ (around the brim of the hat).
The former oscillation is called the Higgs mode and the latter oscillation is called the Goldstone mode.
Show us the photograph on your concessionary travel card, Stephen, and let the thread participants decide!
I read that the Higgs potential generates a large vacuum energy contribution to the cosmological constant or vacuum energy density of the Universe, a prime candidate for the dark energy that drives the accelerating expansion of the Universe.
Tetanus has never been broached by my NHS medics but I will be entitled to the Shingles vaccine when I reach 70years in the summer.
I will definitely be having this because my father's retirement was destroyed by it when he was infected by a grandchild.
It infected the nerves in his face and ear such that his balance was affected and I thought he'd had a stroke when I first saw him.
His passion was his boat and sea angling so that came to a sudden end and nor could he drive.
My last Tetanus injection would have been about 40years ago.
I won't be around when that's working in 2045, asssuming WW3 has not happened in the meantime.
It's a stupid amount of money to spend when there can be no guarantee of any worthwile results and a significant percentage of the world do not have adequate food and water.

Something to look forwards to. If I don't get hit by a car I might last to 104 in 2054. To think the standard model was invented my senior year in college when I was wasting my time studying the eight fold way. Now with the higgs boson demonstrated there are no gaping holes in the model. Maybe someone will come up with a testable prediction from string theory by then. Also by then maybe James Telescope could find a green planet with oxygen.
On the vaccine front I am relishing this winter when the covid vaccine actually came out before I caught the disease. I had every flavor of covid before the vaccine was available except JN1. The flu shot worked too; I have had a repiratory disease free winter for perhaps the first time in my life.
I make that 1950 when you were born, @indianajo!
My Maths book has turned up... Better Late than Never.
Just a cursory glance reveals 2 as the limit. I say this as a Cambridge Mathematician. 🙂

The new machine is called the Future Circular Collider (FCC).

I have extracted the proposed time scale:
It will be BIG!
The varicella-zoster virus is the epitome of patience!
It gives you chickenpox when you are small then may sit inert in nerve cells for half a century or more before erupting as shingles.
It is usually described as a painful rash on the torso, which may explain why its name comes from the Latin cingulus, meaning a type of 'belt'.
Of course shingles can pop up almost anywhere on the body surface. I've had it twice, once on the scalp and once on the back of my neck.
Fortunately, I have now been vaccinated against this nasty virus. 😎
I've adapted information contained within my current read, shown above: The Body (A Guide for Occupants) by Bill Bryson - highly recommended!
The naming gave it away.. similar to other names given in past history to things not understood... like atom, ether etc...

It's worth mentioning at this stage that 1 electron volt is the energy required to accelerate an electron from 0 to 1 meter in 1 second. So when we talk about particles with mass energies of 246 GeV, we are talking about something with 246 billion times as much energy. IIUC this is not the actual energy of the particle, but the energy required to 'distil' it out of the vacuum energy, ie to be able to observe it (Galu, feel free to school me on this, although I realize you will need no encouragement) 😀
Historically, the electronvolt was devised as a standard unit of measure through its usefulness in electrostatic particle accelerator sciences, because a particle with electric charge q gains an energy E = qV after passing through a voltage of V.
So, 1eV is the energy gained by an electron passing througt a voltage V.
In a Cathode Ray Tube with post acceleration 10 000 volt, the electrons hit the screen with a 10 000 eV kinetic energy.

I understand that better by defining an electron volt to be equal to the kinetic energy acquired by an electron when it is accelerated through a potential difference of one volt. (The equation W = QV tells us that 1 eV is equivalent to ~1.6 x 10^-19 J.) EDIT: Written before mchambin's contribution.
A Higgs particle weighs in at ~125 GeV (125 billion electron volts).
In other words, you understand that 125 GeV is not the kinetic energy of the Higgs particle, but is a measure of the 'field excitation' of the particle?
My legendary googling skills are not helping me here, but I've turned up the following statement, which may be relevant:
"The Standard Model does not predict the mass of the Higgs, but an excitation with properties consistent with the Higgs at about 125 GeV."
