Yesterday, Jay-Z's streaming music service Tidal was launched. The press event featured over a dozen celebrity musicians as signing "owners" of the service (each reportedly received 3% equity in exchange for exclusive content), and, by some accounts, was a bit awkward and content-free. At $19.99, the subscription plan is double the cost of competing services like Spotify, and no "freemium" plan is offered. The justification is two-fold: 1. Artists should be compensated fairly for streaming; and 2. The service's high-fidelity, lossless streaming is far superior to the current standard (320 kbps AAC, as Spotify and Rdio currently provide.) You can take an online blind test between 320 kbps AAC and Tidal's lossless streaming, to see if you have the "equipment and ears" for lossless music. Is there really a noticeable difference, or is this snake oil? Will the artist-forward approach change the conversation and ingrained habits of streaming music listeners? Is Tidal a sort of streaming for the 1% rather than for struggling independent musicians? Is it a walled garden for artists at the expense of fans? Or is this all simply a great vertical move for Jay-Z's Roc Nation label? So many questions.
"The Earth tide is a little-known daily event, similar to the oceans' more familiar tides. But the sun and moon's gravity doesn’t just pull on water, it deforms the Earth itself, causing the ground beneath us to bulge toward the pulling heavenly body." [more inside]

Before, during and after. DigitalGlobe's QuickBird satellite imaged the coast of Sri Lanka at precisely the time the tidal wave hit the beaches. It was pure coincidence.
Mention Whirlpools, and people tend to assume you're talking about a Jacuzzi. But not all whirlpools man-made. When powerful tidal currents are forced between a narrow fjord, and then come up against another current traveling in a different direction, the result is a large water vortex. Being tidal means they are predicable. Some of the more famous whirlpools are the Corryvreckian(Scotland), "Old Sow" (Canada), Moskstraumen and Saltstraumen (Norway), and the Naruto (Japan). Notice how they each claim to be the largest of them all. ...Just one more thing to ponder the next time you pull the chain
