Scientists Discover Subatomic Particle

 

Physicists working at the Fermilab Tevatron particle collider in Illinois have discovered a heavier relative of the neutron that they´re calling the neutral Xi-sub-b.

Smashing atoms produced the neutral Xi-sub-b, which lasted just an instant before decaying into lighter particles. Such particles are discovered by racing larger particles around a 4-mile ring at near light speed.

The Standard Model predicted the existance of neutral Xi-sub-b, but the Fermilab experiment is the first time the particle has been observed firsthand. The particle joins the three-quark baryon family which also includes protons and neutrons.

  I met the Baryon family once.  
 
Nice folks. Kids are kinda crazy but that´s how it is with leptons these days.

  Wait a sec...  
 
Who gives a crap about Xi-sub-b?! After nanoseconds it was obsolete due to the even smaller particles! Stupid self-deprecating subatomic particle...

The importance is, at the moment, not in the particle itself, but in the fact that it exists. This is true of many particles we´ve found.

The Standard Model of Particle Physics is a theory of particle(both mass and energy) behavior and composition. A number of particles are currently predicted by it, but have yet to be found. Finding a Xi baryon gives greater confirmation of The Standard Model.

  Atom walks into a bar  
 
... says, "I think I´ve lost one of my electrons!"

Bartender says, "Are you sure?"

Atom says, "I´m positive!"

"just a beer"
He replies
"What´ll you have?"
and says
The bartender looks at him
he sits down
Head to the bartender and
A tachyon walks into a bar

I´d never heard that, that´s hilarious! :)

Another physics joke:

Heisenberg gets stopped by a police car.

Officer says, "Sir, do you know how fast you were going?"

Heisenberg replies, "No, but I know where I am."

  I need a punchline  
 
Erwin Schrödinger walks into a bar.
The bartender says "Erwin, What´s with the dead cat?"


Come on. There´s got to be a joke in there.

Haha. Love that one. The other version of that joke has Schrodinger in the car as well.

After talking to Heisenberg, the officer decides to search the car and finds a dead cat in the trunk. He comes back around and says "Do you realize you have a dead cat in the trunk?!"
Schrodinger replies, "well, I do NOW."

  Bada boom  
 
A neutron walked into a bar and asked, "How much for a drink?" The bartender replied, "For you, no charge."

LOL! Thanks for that.
