Diodes work on the concept of biasing. When reverse biased no current will flow as it acts as an open switch. When forward biased and with a voltage drop greater than ~0.6(this is required to close the "switch") it allows current to flow. There is a more in depth explication but this is the shortest I could come up with.

Doesn't work because it's wired in backwards. How's that for short? ;^P
