Dan Meyer: Math class needs a makeover. What Is the Higgs? - Interactive Graphic. Imagine never having seen a snowflake. Now prove one exists by probing the slush and mist of melting snow. You can’t see a Higgs boson, and no sensor can pick one out from the Higgs field that it forms. For 50 years, physicists have been building larger and more powerful accelerators to vaporize particles and sift through the debris. In the tunnels at CERN, protons are sped along a track to within a breath of the speed of light, then smashed together in a violent explosion. The protons annihilate each other, releasing a burst of energy. But Einstein tells us that mass is energy, and physics tells us that energy can’t be destroyed. An array of new particles pours from the fireball, energy spun back into tiny specks of mass. A machine surrounds and tracks the debris, bending charged particles as they plow through layers of sensors.
Repeat this a million times, then tens of millions, before a second has passed. And keep going because you’re looking for something very rare.

Creationism Is Not Being Ignored On 'Cosmos' By Betsy Phillips, Guest Contributor "Creationism Is Not Being Ignored On ‘Cosmos’ — It’s Actually The Focus" CREDIT: Frank Micelotta/Invision for FOX/AP Images Danny Faulkner, a “scientist” working for the same group that runs Kentucky’s creation museum was complaining last week that Neil deGrasse Tyson’s Cosmos: A Spacetime Odyssey doesn’t address creationism.
From Mashable: Faulkner claimed the 13-episode series has a distinct “evolutionary bias,” and agreed with Mefferd’s concern that Cosmos doesn’t even present creationism as an alternative theory. This seems to be the prevailing sense on the other side as well. Actually, Tyson is deliberately and straightforwardly giving a whole lot of time to creationism. Another example: Why did Tyson spend so much time explaining the similarities and differences in how polar bears have evolved through natural selection vs. how dogs have changed in the time we’ve been breeding them for certain traits? Tyson isn’t ignoring creationism. Khan Academy. From kindergarten to calculus, Khan Academy is here to help.
