Thank you for cutting through all the "science journalism" or whatever bullshit, and actually bothering to put the _science_ in context (with some humor too!).

It's _definitely_ too early to dismiss all but the Standard Model - there's definitely a lot more exciting stuff to come from CERN... hang in there!

Thank you! It seems very few people understand the immense pressure and intense atmosphere that surrounds work like this, especially in culminating times like these. Fabiola would likely rather spend her time improving the quality of her an

When scientists present results to scientists, they present in a scientific way. I.e. methods, analysis, etc. There is no way a scientist can get by with just a short summary when talking to fellow researchers... it's just not how science i

Clearly you don't understand how much time pressure these people are under. If you were at CERN you would realize how intense the atmosphere has been in the past 2 weeks. Also, focus on the content - if you're caring so much about the prese

There is no known outcome. "what are our governments buying for us?": - knowledge - possible future applications It's that simple. That's always how fundamental research works. How politicians were convinced, I don't know - that's an excell

Fundamental particles enter the Standard Model through the Lagrangian. Each particle is given its own field in the action: [ http://en.wikipedia.org/wiki/Standard_Model#Construction_of_... ]. I'm not quite sure what you mean by "orthogonal"

Classically, yes. Quantum mechanically, acceleration is a rather ill-defined quantity, so I don't know how to answer the question other than through Ehrenfest's theorem - <F> = m <a> when we're talking <averages> [ h

Photons can have momentum, which, when doing relativity, blends together with energy into the momentum 4-vector [ http://en.wikipedia.org/wiki/Four-momentum ]. Relativity also asserts that energy and mass are related [ http://en.wikipedia.o

Elementary particles have no volume! (think about that one, it's kinda mindblowing) They can only have "effective size" that arises due to say, electromagnetism. The electron has an effective radius that is measured by bouncing other charge

There is a single Higgs field. But the Higgs field can be excited in many different places! Same for anything else, like an electron - that's why we say that two electrons are indistinguishable from each other. Fundamentally, they're made o

Quantum theory is based on the concept of wave-particle duality. Think of the ocean. The water as a whole is pretty wave-y and non-localized (i.e. it's not in one place). But the crests of the waves (the "excitations") can be thought of as

fjh - thank you. That is exactly the spirit of science.

Both ATLAS and CMS have legitimate, crazily cross-checked data and therefore they are releasing it. That's all. This is how science is done - all CERN is doing is updating the world on its of progress the search for the Higgs boson. Sure, s

No ATLAS or CMS member is currently allowed to release these numbers. Then numbers these sites are releasing are just pure rumors (although they may have an element of truth). Just wait until the press conference tomorrow and you will see a

We don't yet know if whatever we see is or is not the SM Higgs. That's why the LHC is scheduled to continue running through the year, so we can get more details. All we can really say at this point is we see something. Heck, we've been able

I still find it hard to see any practical, hard benefits of switching to tau. Perhaps you could argue that many things become "more natural" but at this point, pi is ingrained in mathematics, and it works perfectly well. I just can't imagin

I don't think conservation of momentum is under fire here - the vacuum fluctuations (due to second quantization, quantization of electron, quark, etc. fields) might pick up the difference... although I don't really know enough QFT to be def

Ah yes, I was looking at some of Wikibooks - it doesn't seem too developed yet; hopefully that will change. Hmm, I agree with your issue with the lack authority, and honestly, I don't really know what to say. Having something like this peer
