Does this explain what generates gravity?

I want to argue we should be grateful to cern or any other Institute which are actively involved in finding stuff.
Inventions made this world lounge possible.
How much money do you think invention of transistor have made us so far. Might go in zillion if you ask me.
Your money is worth less without somebody selling the stuff you need.
Also research means finding the unknown. No point in searching what already know. And they there's no surety either.
Humans as a species is so stupid. Sometimes I feel who we actually managed so far.
I agree up to a point.

Everything comes down to money and there must come a point when governments funding CERN have to say no.
Governments don't have money of their own - it belongs to their tax payers who never have any say in how it is spent.

I don't know how much the LHC cost and have yet to hear of the tangible benefits of proving the Higgs Boson exists. It has just led to the demand for over £70B for a larger collider.

I don't know how much the UK pays towards the cost of this research but however much it is, we need it for other things, like Dentists and more mundane things like repairing the roads.
 
snip...Putting serious hat on, can anyone confirm I have differentiated Gamma correctly with respect to v?

View attachment 1270258

I make it -1/2 x -2v/c^2 x Gamma ^3.

= v/c^2 x Gamma ^3.

I need this step to evaluate the frequency and wavelength of matter waves at near light speed. De Broglie, an' all that.

Best, Steve.
To reiterate the equation I am trying to differentiate:

Anybody know if this is right? I seem to have a mental block on it, and cannot confirm the exact solution anywhere. The integral is easier to find. 🤔

On the question of £70Bn for a larger collider, a lot of people don't think there is anything to discover above the Higgs and Top Quark.

Supersymmetry being part of String Theory... and that is unproven. To its credit, CERN does a lot more than Higgs interactions. Muon research for one thing.

It is also an inspiring collaborative World project, funded Internationally.

Apparently 80% of the Physicists who have ever lived are alive right now, and need encouragement. Prof. Brian Cox was inspired by the Moon landings.

And I have enjoyed all the images of Planets and the Galaxy and Universe (JWST for instance) which we have seen lately.

But generally speaking, fundamental research pays for itself rapidly. Spin-offs like Teflon frying pans, CAT scanners, the aforementioned transistor and the Internet spring to mind.

I never buy the "better spent on the NHS" argument. Surely you can have both! 🙂

Both systems involved (per moving) do see the same:
Relativity = egality = symmetry;-)
NO "time dilation" or "lenght contraction"-)
No fairy tale beings like Black holes, wormholes, donut- or hopper-universes and so on;-)

Indeed, I've checked out your post #3,339:

Great picture, but: the driver does see the same!
a) images only! b) mirrored images: cancel each other out!
No special and general relativity of Einstein!
No "spacetime", that does expand, or is curvable, bendable, stretchable...-)
Doppler effect only;-)

Now you finally got it;-)

Yes, I've finally got it. You think that special and general relativity can be explained by the Doppler effect.

What a happy and uncomplicated Universe you live in! 🤓
 
Costs are analysed in this 2012 article: https://www.forbes.com/sites/alexkn...t-cost-to-find-a-higgs-boson/?sh=37156d253948

The LHC was constructed for a total cost of about $4.75 billion.

The total cost of finding the Higgs boson ran at about $13.25 billion. That's a large amount, but there are over 50 billionaires on the Forbes list actually worth more than that.
Maybe those 50 Billionaires should pay for the new collider!
They would if they could see it as a good investment which it isn't, at least not in the short or medium term, if ever.
 
Developpement of super magnets, supraconductivity at near 0°K, for giving lot of Teslas gave IRM.
IRM an imagery technic available in every modern clinic, to probe deep in your brain, lungs, arteries, kidneys and all parts of your body.
This saves lives, every days thanks to big science magnets. And they will developp stronger magnets for the future CERN collider..
I do not care the cost, i do care for lives.

We are getting ever closer to fusion reactors becoming viable but not commercially until 2050.

That would be fantastic!

There's a long-running joke that fusion is the energy source of the future - and always will be! 😀

I wonder how ITER (International Thermonuclear Experimental Reactor), the world's largest fusion project, is getting on?

"The ITER project involves 35 countries in the construction of a huge test reactor in Southern France. It is hoped that the ITER Tokamak will eventually produce 500MW of fusion power for 50MW of input heating power. The plan is to have the first plasma produced by 2025, but it is unlikely that a working fusion plant will be up and running before 2050."

Unfortunately, I read that the project may be in great trouble due to accumulated schedule slips and budget overruns: https://www.scientificamerican.com/...oject-is-in-big-trouble-new-documents-reveal/

Steve, here is your answer courtesy Photomath

That's dɣ/dc, whereas Stephen asked for confirmation of dɣ/dv. ("can anyone confirm I have differentiated Gamma correctly with respect to v?").

But what would I know about differentiation other than c is a constant and v is a variable? I wonder why Stephen needs the relationship?

Our UK JET lab has reported a world record amount of energy from their reactor - 69megajoules for 5seconds. They don't say how much was needed to generate it!

69megajoules for 5seconds.

That is JET's swansong after four decades of operation - only enough energy for four to five hot baths!

This illustrates the extent of the challenge faced by ITER, the plans of which have now been pushed back by at least 10 years.

1707480290085.png


JET's tokamak employed a doughnut-shaped plasma ring, but ITER's spherical design will achieve a much higher plasma pressure for a given strength of magnetic field containment.

The objective remains the same - to fuse the heavy isotopes of hydrogen, tritium and deuterium, under extreme heat and pressure.

Now multiplying top and bottom by 1/c^4 and SQRT(c^2 - v^2), gives v/c^2 x Gamma ^3... back in terms of the Lorentz factor.


QED! Thankyou, Bonsai. We seem to be in accord! Now I've just got to figure out the rest of @Galu's matter waves problem... 🙂
