This week on Crash Course Economics, we're talking about monetary policy. The reality of the world is that the United States (and most of the world's economies) are, to varying degrees, Keynesian. When things go wrong, economically, the central bank of the country intervenes to try aand get things back on track. In the United States, the Federal Reserve is the organization that steps in to use monetary policy to steer the economy. When the Fed, as it's called, does step in, there are a few different tacks it can take. The Fed can change interest rates, or it can change the money supply. This is pretty interesting stuff, and it's what we're getting into today.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Only a couple of decades after the end of the First World War--which was supposed to be the War that Ended All Wars--another, bigger, farther-flung, more destructive, and deadlier war began. Today, you'll learn about how the war in Europe progressed, from the Molotov-Ribbentrop pact and the invasion of Poland, to the Western and Eastern fronts, to VE Day and the atom bombs used in Japan.

Countdown to Kindergarten
by Alison McGhee
Illustrated by Harry Bliss
Read by Let's Read Stories

It's just ten days before kindergarten, and this little girl has heard all there is to know--from a first grader--about what it's going to be like. You can't bring your cat, you can't bring a stuffed animal, and the number one rule? You can't ask anyone for help. Ever. So what do you do when your shoes come untied, if you're the only one in the class who doesn't know how to tie them up again?
Told with gentle humor by Alison McGhee and brought to exuberant life by New Yorker cartoonist Harry Bliss, this lighthearted take on pre-kindergarten anxiety will bring a smile to the face of every child--and parent--having first-day jitters.
