Re: Precision electroweak physics by ATLAS

Can you just go somewhere else if you don't want to contribute anything? Uh, you made your contribution, I expressed an opinion, isn't that how this thing works, chatting about science … anyone can join in. BTW I can understand that refining the measurement is an achievement, but on a scientific le...

Re: Precision electroweak physics by ATLAS

The W electroweak gauge boson was discovered in 1983 at the CERN SPS collider. Although the properties of the W boson have been studied for more than 30 years, precise measurement of its mass remains a major challenge. So now over more than 30 years of doing 'research' they came up with these resul...

Learn actual science.
Can confirm.

Read up on what's already been done.

Re: TED - How we explore unanswered questions in physics

This is not "particles and cosmic rays". The introduction is about the attempts to unify quantum mechanics and general relativity, and the bump that appeared in 2015 could have been a graviton - a first experimental hint how to combine those two. That wouldn't have been just another particle, it wo...

TED - How we explore unanswered questions in physics

So weird this talk. http://www.ted.com/talks/james_beacham_how_we_explore_unanswered_questions_in_physics Particles and Cosmic rays have been detected for more than 100 years and he talks like we have just discovered a new planet. Fact is that we have been already going through the fine sand for dec...

Summary: The LHC found something new and surprising in every year so far. You sound like a gambling addict. Look at your list, aside from the Higgs you hardly found anything. You simply can't and won't stop. :mrgreen: Oh and sure the World Wide Web isn't the same as the internet, I am sorry. :oops:

Re: LHC's Newest Data: A Victory For The Standard Model, Def

Sure, colliders have been great … but like Ethan said they aren't going to reveal any new physics. Regarding CERN giving us the internet that is a little pretentious don't you think. You should read Walter Isaacson's book The Innovators: How a Group of Hackers, Geniuses and Geeks Created the Digital...

Re: LHC's Newest Data: A Victory For The Standard Model, Def

Fair enough, but this brings us back to Ethan's first line:
It means that colliders aren’t the answer. It means the LHC won’t reveal new physics …
There are still some details to be 'noted' but collidors aren't teaching us anything special, the bang for the buck ratio is pretty low.

Re: LHC's Newest Data: A Victory For The Standard Model, Def

The same applies to all other properties - spin, parity, branching ratios, cross sections, angular correlations, ... - they do not change over time. Well at some point (~now) you start ending up with something like the 3 body problem, where you can keep on collecting data but it is no longer adding...

Re: LHC's Newest Data: A Victory For The Standard Model, Def

You are right. I was looking at the part where he used the weasel word 'might': "What's the takeaway? That the Standard Model might be all our particle colliders can access in our lifetime." Meteorologists measure daily rainfall and sunshine, which is similar to your daily 'measurements of particle ...

Re: LHC's Newest Data: A Victory For The Standard Model, Def

There are several physicists in high-energy physics with pessimistic outlooks. The difference to Ethan Siegel: they do not rule out the possibility to find something (they just think it is unlikely), and they have actual physics arguments. Ethan said the same thing, that it is unlikely. His conclus...
