cagraham writes "The Wall Street Journal reported this morning that Amazon will begin charging customers in Connecticut, Massachusetts, and Wisconsin sales tax today, after fighting against it for years. Amazon now charges sales tax in 16 states, affecting roughly 163 million Americans. Yet despite Amazon's continued fight against sales tax on the state-level, they support a Senate bill that would allow all states to tax online retailers. It seems like a contradiction, but it's actually a calculated move to undercut rivals like eBay (who would have a far harder time dealing with sales tax laws), and even an unequal playing field (many states that tax Amazon don't tax other online retailers)."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
