I got to join in on a great conversation this morning on Minnesota Public Radio's "The Daily Circuit", all about the Higgs Boson and what it means for the future of physics.
This is a fascinating issue. Finding the Higgs Boson (if that is, indeed, what scientists have done) means that all the particles predicted by the Standard Model of physics have now been found. But that's not necessarily good news for physicists. For one thing, it would have been a lot more interesting to break the Standard Model than to uphold it. For another, we're now left with a model for the Universe that mostly works but still has some awkward holes — holes that it might be hard to get the funding to fill.
Daily Circuit host Kerry Miller, Harvard physics chair Melissa Franklin, and I spent 45 minutes talking about what is simultaneously a beautiful dream and a waking nightmare for the physics world. And I got to make a "Half Baked" reference in a conversation about particle physics, so you know it's a good time, too.
The discovery of the particle that is most likely the Higgs Boson was met with wild-eyed excitement almost everywhere except CERN, writes physicist Glenn Starkman at Scientific American Blogs. That's because it means the theoretical Standard Model of Physics is probably on the right track. Which means there aren't any crazy inaccuracies leading to awesome mysteries that must be solved. Which means experimental particle physics haz a sad — and more than a little depressive ennui. (Via Alexis Madrigal at The Atlantic)— Maggie
Buttons glow in the control room of the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (CERN) near Geneva on April 5, 2012. At 0:38 CEST this morning, the LHC shift crew declared "stable beams" as two 4 TeV proton beams were brought into collision at the LHC's four interaction points. The collision energy of 8 TeV is a new world record, and increases the machine's potential to solve perplexing scientific questions.

Synchrotrons are a type of particle accelerator—a family of machines that includes the famous Large Hadron Collider.
Different synchrotrons do different jobs. The Diamond Light Source synchrotron in the United Kingdom focuses on producing high-energy beams of light, which are used to aid all different kinds of scientific research—from microbiology to archaeology.
In this short video, Harriet Bailey and Alice Lighton of Elements, a British science news page, explain how Diamond produces light to begin with and how synchrotrons work. They do this, using a model built out of donuts.
Data from Fermilab's shuttered Tevatron accelerator seems to support the data released by CERN last December. These two different accelerators are both seeing a signal that could be the Higgs Boson in roughly the same place. To quote the New York Times: "It has led to a joke in physics circles now: The Higgs boson has not been discovered yet, but its mass is 125 billion electron volts."

"They said when the collider goes on
Soon they'd see that elusive boson
Very soon we shall hear
Whether Cern finds it this year
But it's something I won't bet very much on."
