  • Suppose you're ambitious enough to try to describe everything in the observable universe

  • in one single mathematical equation. DONE.

  • OK, so that doesn't include gravity or a few other little thingsbut the point is, this

  • equation describes, with incredible precision, what the earth is made of, what keeps the

  • sun burning, what allows us to breath, taste, mow the lawn, blow things up, and watch internet

  • videosall in one equation. And it's humbly called "The Standard Model" - because even

  • when they discover the most accurate scientific theory known to man, physicists are modest.

  • Now, the universe is a pretty big place (maybe even infinitely big), so it's reasonable to

  • think that you might need a lot more than just one equation to describe it all - so

  • why is the standard model so simple? For starters, it's more like a recipe - and just as a recipe

  • for cake assumes you already know how to sift flour, beat egg whites, build an oven and

  • grow wheat, this equation assumes you already know about path integrals, gauge theories

  • and so on - so there's a lot more than meets the eye.

  • As for why an incredibly small set of mathematical rules appear to govern the universe? Well,

  • that's a deep and unanswered question. But the data show that math is the language of

  • the cosmospick a few elementary particles, set them on a high-energy collision course,

  • and BAM! When the sparks fly, the standard model will describe the fireworksto twelve-decimal

  • places of precision!

  • Anyway, in the next few MinutePhysics videos we'll explain all sorts of the cool ingredients

  • that make up the standard model, like quantum fields, fundamental forces, quarks, gluons,

  • ghost particles, and of course, the higgs field. It's an ambitious task, and I hope

  • you're ready for it!
