Surfing gravity's waves still tough after decades of trying : Comments

By Mark S. Lawson, published 5/6/2015

Ever since Einstein theorised that gravity waves existed, scientists have been trying to detect them. That century long quest may soon be over.

Ah, I see the problem now, spindoc. You haven't the faintest idea what any of the things you're quoting actually mean and you certainly haven't read any of them.

I'll simply give you one example, from your cited link http://www.phy.duke.edu/~hsg/162/files/homeworks/assignment-03-jan-26-2015.pdf

"In this problem, you use Gauss's law several times to develop a crude but insightful classical (non-quantum)"jelly" theory of a helium atom"

Which compares to your claim: " Finally, show that you understand the meaning of Eq. (2) by drawing ... quantum)“jelly” theory of a helium atom …."

I won't call you wilfully dishonest, spindoc. The reader can draw their own conclusions.

In case you were a bit stuck with the problem, Gauss's Law states that the electric flux through any closed surface is directionally proportionate to the total charge contained within.

Good luck :)

' morning Mark,

Just received this press release from CERN this morning announcing the restart of the LHC this month.

The 27 month upgrade has taken energy levels from 6 TeV to 13 TeV with which they hope to probe particles at higher energy levels than those detected in current QED/QCD physics.

For anyone interested there are some stunning images of proton collisions.

Hi spindoc, it's nice of CERN to take the trouble to send you press releases.

I hope the boys at Zoo got theirs, they're all high energy physics buffs over there.

'morning Craig,

I don't think it's too much trouble for CERN to email updates to subscribers? If you wish to get your own updates you can use the links I've already provided and the service is free. Since it is a topic you are so passionate about you might enjoy the information.

Craig, I don' t quite know how to say this so I'll start with an apology. I've done my share of abuse on OLO and even received a one week ban from GY. I do apologise for baiting you and I mean that.

Having recognised your predicament much earlier I had no right to continue to provoke you and I'm so sorry for that.

My guilt on this issue has much to do with the movie The Rain Maker, starring Dustin Hoffman. I do understand, I do apologise and will in future restrain myself accordingly. Sorry mate, hope you can find forgiveness.

spindoc,
you're quite right, CERN do a great job at informing the public of their work. It's actually part of their role as a publicly funded science organisation. I'm an enthusiastic supporter!

I'm happy to accept your apology, in the spirit of John Nash (A Beautiful Mind), who claimed to have managed the feat of unifying QM and gravity shortly before his death, according to the great French mathematician Cedric Villani. It will be interesting to see if Villani publishes on the subject. It is quite believable that Nash did so, given his groundbreaking work on embedded geometry
