What the heck is a Higgs Boson?

Know your particles
There’s also this rather helpful table of particles for those who are still not convinced they know their quarks from their leptons:
Basically, the Standard Model bits are the elementary particles, the things that make up all of the stuff we can actually see around us and understand. The world. Objects. People. Things. The sky.
Then there’s the Quarks, the bits that come together to form protons and neutrons and all that good stuff that makes up the nuclei of atoms today.
Hot on their heels are the Leptons which come in charged and uncharged versions. Even non physics boffins know what an electron is, and an electron is basically a charged Lepton. Combine Quarks and Leptons and you have pretty much all the matter your eye can see. Uncharged Leptons are neutrinos and they don’t seem to do an awful lot, as they are a bit antisocial and rarely interact with matter.
Next up, my favorite, the "force carriers." Sadly, no, these are not characters from Star Wars, they’re particles whose movements are observed as familiar forces like electricity and light. Electromagnetism if you will. They are also a major factor in radioactive decay as a weak nuclear force.
Last, but as we’ve discovered, certainly not least, there is the Higgs boson, the stop gap in particle physics which gives everything else meaning. Because without mass, there is no real substance, and without substance, there is no real meaning. Right? So Higgs, is the physical glue that holds our rather basic understanding of physics and the entire universe together. No pressure or anything.
Either way, now that CERN has found evidence that Higgs Boson exists, you can all sleep easy. Even though the meaning of life, the universe and everything is still 42.

video too long.
Can the Higgs make me happy? Does it mean we can travel faster than light?
Should be easy enough to say yes or no.

Neat, thanks (for each page, at that); next fundamental waveform I hope for a sort of vertical-farm/larder/kitchen layout chart with Maxwell's Equations in a rhombus and some choice arrows or bluelining. You can go all Higgs Starbuck again.

GoStripes, BTW sorry to break the news this way, but u asked for it, for the simple answers that you seek: There is no Santa, nor Tooth fairy and neither gold awaits for you at end of rainbows.
FYI, the electron's presence and its benefits
were discovered some years back. And modern life is happier because of that.
Sylvie,
Good video, science will never appeal to some people unless they see an immediate personal reward. So I wouldn't bother with a shorter version. ;-) IMHO

I liked the video. I would be interested in seeing a more in-depth detailed video. Why does the Higgs-Boson bump show up in the middle of the y-axis of the graph? And what does "Boson" mean? And what is the relationship between the Higgs-Boson particle and the Higgs field? And finally, is negative mass a proven impossibility? If I could eat a burger that had negative mass, would I lose weight? Perhaps I should look at the wikipedia as well.

I think the bump is not necessarily in the middle of the curve. I think all he's saying is, just like the other particles are produced with just so much energy, so would the Higgs boson. Less energy or more energy in the collision, and you get other particles than this Higgs. So you need lots and lots of trials to get JUST the right amount of energy to create this new particle, in a way that's detectable (statistically significant).
Higgs field is to Higgs boson as EM field is to photon, looks like to me. One is the field theory, the other the particle theory.
I also kept getting stuck on this dismissal of negative mass. Watch for the emergence of a twin to the Higgs boson, like with negative spin, that gives matter a negative mass. Intriguing to think of parallel universes, e.g. where mass is imaginary of negative? (Imaginary mass must only travel at speeds greater than c? Negative mass absorbs energy?)

Moving to the very large, gravity should be slowing the expansion of the universe, yet we observe that it is not. Something is pushing the galaxies apart. Dark energy is the term originally given to whatever force that is. One possibility is that where ordinary matter attracts other ordinary matter (gravity), ordinary matter repels dark matter (antigravity). Or perhaps the dark matter increases the mass of the universe, and so the total energy of the big bang, to the point where it simply hasn't had time to stop expanding yet. Who knows?

These theoretical physicists are really funny. Everytime they measure something their equations cannot explain, they add something to their equations to cover it. They call that thing a funny name and give it a weird explanation that nobody can understand, not even them really!
There is nothing fundamentally new theory-wise since the days of Einstein, Max Planck and the likes.... lazy science if you ask me :-)

Einstein did exactly that on his Equation of the Universe from his general relativity theory:
1. The solution from original equation shows the universe was expanding--against earlier 20s century view. He added a universe constant to balance the expansion.
2. When Hubble in the 1930s observed the universe was indeed expanding. Einstein called his addition of the equation was his "biggest blunder".
3. But nowdays since the dark matter/dark energy, the physics community was right with the addition: if he moved the term to the other side of the equation, it will naturally explain the dark energy!

I had been searching for a good explanation over the web on the Higgs particle. This is so far the best one. Thanks for posting this.
It depends how people perceive the importance of Higgs particle discovery, hence some likes it while it may not mean much more than just a video.
If one looks back in time where only 90plus elements were discovered, every new discovery got harder and harder after that, it is sort of the same plight here, but orders of magnitude harder because everything goes up, energy, $, techniques, skill etc..and the time scale of these interaction gets smaller and smaller. For engineers, think about doing something like TeraTeraflops in fractions of a second with high accuracy..how does the design rule, device mechanism and heating mechanism be controlled,what is the chemistry? How to analyze this data?
It deserves all the worth of it to understand the gene of all things.

There is a big difference between claiming that you "Think" you have found a Higgs Boson and actually proving that you found one.
I think you can go back to Einsteins equations and his statement that "God does not throw dice", to conclude that there are simpler explanations for the universe than the need for this particle. Please remember, Quantum Mechanics is still just a theory.
Just my opinion,

I am always shocked when I hear the word "just" lumped with "theory". And on a technical website yet! A theory in the science and technical world is a set of well tested, and widely accepted explanations for known facts.

Correct, although how well supported and how widely supported differ from one theory to another. I would also add that any scientific theory must be falsifiable. Until someone can prove it is false, a scientific theory remains valid (as it is supported by observation and experiment)

Farming and deep-well petroleum exploration are theories, too; nobody books rain ahead, goes 7 miles down with a headlamp, or makes up the difference by accelerating in a faith field. And no, nobody actually works in math, fine art, particle physics or governance making Fractional Hall Positron Matter; it is tortoises, Alain Greienspan, vim, tcsh, and a big bag of azure kush all through.
Yes we still have a long way to go, before we can grant 2-year certificates in Quantum Mechanics instead of Java; but as we get close, it will become possible to make an arbitrary mass of chocolate and hard cheese out of 1kg of chocolate and hard cheese (and take them 7km down a bore with a touchstone.) Or, book the foundations for cosmic safety and commerce if anyone gets out the vote for that sort of garbage.

Very interesting video. Kind of Higgs-for-dummy. I am curious how many particle physicists are out there. Given the size of the community there is lot of money and visibility. Hope it is real. Not like Y2K by the turn of last century when billions were poured to solve imaginary problem.

Y2K was a real problem but by working on the solution before it occured it became a non-problem. Just like a house not burning down because you replaced a faulty device in the house HVAC.

Nah, I have my doubts. Some countries, e.g. Italy, did virtually nothing about Y2K, and they didn't have any problems either.
Perhaps a more likely problem will be when the NTP time stamp turns over. Which will occur 7 Feb 2036 at 06:28:16 GMT, when we transition to Epoch 1.
Off topic, though. Soeaking of which, Gordon's post below was quite hilarious.

Not totally imaginary. I used Quicken 99 at home. It let me enter year 2000, no problem. I then did the "real" Y2K test by advancing the computer date to 2000 and entered some transactions OK. I was smug, but deceived with over-confidence.
When the real 2000 rolled around I soon discovered that my Quicken 99 wouldn't enter any 00 dates automatically (if I remember correctly). I had to go out and buy Quicken 2001 to get it to work correctly.
Moral to the story? My simple test wasn't thourogh enough. You gotta be really careful before making serious proclamations.

Off-topic really but I loved this...
The Higgs Boson is called "The God Particle" and it's purpose seems to be to give Mass to all the other particles.
Proof at last that God is a Catholic.

Guys, according the Standard Model (SM), you own everything to this "Higgs Boson": it generates mass(yeh, say you weigh 212 pounds!).
W/O Higgs boson,no mass, no pretons, no electrons, no elements, no stars, NO sun, no earth, no human, no ICs!

"Perhaps a more likely problem will be when the NTP time stamp turns over. Which will occur 7 Feb 2036 at 06:28:16 GMT, when we transition to Epoch 1."
I think a bigger problem will occur on Jan 18, 2038. That's when most PC's time counters roll over (unless they switch to a 64 bit timer).
Here's a simple Perl program to test it out:
print ":",scalar localtime(2147483645),"\n";
print ":",scalar localtime(2147483646),"\n";
print ":",scalar localtime(2147483647),"\n";
print ":",scalar localtime(2147483648),"\n";
print ":",scalar localtime(2147483649),"\n";
On my PC and Perl software, it prints the date only for the first three times.

Perhaps too, I don't think there is much that is more important to the human race than discovery. It is "eating the apple" that makes us unique, after all. As far as I'm concerned, there are not many more worthy causes to sink some money into.

The Higgs boson represents the culmination of the physicists' biggest welfare project to date. It keeps them employed and they can but billions of dollars worth of equipment and instruments, which makes the suppliers happy. As far as I can tell, neither the Higgs boson nor knowledge about how the universe started with the Big Bang have any importance to daily life. So it's discovery is a non event with no significance except to the Nobel Prize committee; and what do they know? Years ago the Nobel prize in medicine went to the doctor who devised the frontal lobotomy. And more recently the Nobel Peace prize went to Yasser Arafat. Take it from a scientist, the Higgs boson means nothing.

This is one of the most short-sighted comments I've ever seen - and they abound on the internet. Your statements belie you assertion that you are a scientist. The computer and network that allowed you to post your comments were made possible by the work of physicists whose work was purely theoretical when it was new; but it was elaborated on and tinkered with and then applied by engineers to make the electronic world we live in.

You know I thought the neutron was simply a proton and electron fused together. From a mass and charge point of view that is true.
Yet the video didn't draw the neutron that way, instead using a combination of those u and d things.
The problem with this video is that it doesn't really tell me what the Higgs boson is. If it is a particle that gives other particles mass, that means every particle that has mass must be made up of Higgs bosons. But how?
