Why Physicists Need the Large Hadron Collider
Google Tech Talks October 17, 2008 ABSTRACT The LHC is the biggest (27 kilometers around) scientific instrument ever built and it is now ramping up to start taking data. It smashes together protons at enormous energy in order to create new forms of matter. Physicists hope to find the Higgs Boson which is the missing link in our current theory. Hopefully unanticipated discoveries will be made. I will explain why physicists need this expensive tool in order to understand nature at the smallest distance scales. Speaker: Edward Farhi Edward Farhi was trained as a theoretical particle physicist but has also worked on astrophysics, general relativity, and the foundations of quantum mechanics. His present interest is the theory of quantum computation. As a graduate student, Farhi invented the jet variable “Thrust,” which is used to describe how particles in high energy accelerator collisions come out in collimated streams. He then worked with Leonard Susskind on grand unified theories with electro-weak dynamical symmetry breaking. He and Larry Abbott proposed an (almost viable) model in which quarks, leptons, and massive gauge bosons are composite. With Robert Jaffe, he worked out many of the properties of a possibly stable super dense form of matter called “Strange Matter” and with Charles Alcock and Angela Olinto he studied the properties of “Strange Stars.” His interest then shifted to general relativity and he and Alan Guth studied the classical and quantum prospects of …

A theory is called a theory to have realization that we learn more and more and more. So most theories including Einstien’s and Newtons theories will evolve the principle will still be relevent. Therefore, that in mind we really should not consider any law. The flat Earth was law too, then what happened? lol. Classic how non-scientists think they know things.

This guy sucks at explaining physics. Read a book you’ll retain more.

awesome talk
where’s that accent from?

And where is your 40 tev collider. nowhere because you could not make it, lamer

Sounds more like a bad explamation of star creation, not the big bang. Also you mentioned space, there was none prior to the BB.

Creating the big bang
July 19th, 2010 at 11:40 am
My reason for the big bang is hundreds of thousands of billions of particals floating around in the fast void of space slowly moved closer each milenium and when they got a couple coliding with each other they created a magnetic field..more meleniums later They come closer to those particles closer and closer faster and faster and faster untill they all come to form a little ball of particles so condence with Trillions and trillions of them And then when the force became so great they exploded

make a new universe

you idiot why say nothing you always learn something
July 19th, 2010 at 1:37 pm
are you dumb
July 19th, 2010 at 2:10 pm
lol not

He is a good speaker.

Ignore gravity at the sub atomic level? What is the strong nuclear force and gravitation one in the same force? This would explain why it’s so weak.

scientific claims do not pertain to the supernatural. you have no idea what you are talking about, and are spamming.
July 19th, 2010 at 3:58 pm
let time, lols, rethink what u’ve written here. moron
July 19th, 2010 at 4:41 pm
Here something you should think about. How come Common sense itself contradicts “the word of God.” Also, Why does the BIBLE CONTRADICT ITS SELF. and finally, why don’t you shut the fuck up and go read your fucking scriptures.

Many struggle to answer with scientific credibility key questions about God, the Universe and the Bible. But Higgs Boson or not, God is most definitely real. If you doubt it, read ‘the attempted murder of God’ – A critical book at a critical time, it reveals the secrets of science that comprehensively demolish the theory of Evolution and provides scientific proof for God – a scientific certainty kept hidden from the world that in this critical time in history can now be revealed.

I know….pisses me off..I would have been so dern excited to have such an amazing machine in my state. lol!
xoxoxo

@MadMadamJess
yup….. but then the idea was dropped.
Oh America…..

good lecture. the original Super Collider was here in Tejas…in Austin..which was gonna be at 40 TeV..the LHC is a measly 14 TeV..lame. Favorited.
xoxoxo
luv,

Fuckin Nazi’s, yet another Freemason fake Holy Grail scam to make big black hole’s in the World’s econemy!
July 19th, 2010 at 8:26 pm
OK, I asked too soon. He answers this question near the end of the lecture. Sorry!

Can someone explain how we know the mass of the Top quark is 170GeV yet we can’t tell if the Higgs boson mass is greater than 115GeV until we collide particles at energies that have not yet been achieved? In other words: by that logic, wouldn’t we still be searching for the Top quark too?
