"The National Sports Daily, on the one hand, is a long-dead and short-lived newspaper that, for 18 months, between January of 1990 and June of 1991, attempted to cover sports in a way that no other American publication would, could, or had ever even imagined. On the other hand, the paper is emblematic of the parts of culture and media that were not yet ready to converge. Typewriters and satellites. Mexican titans of industry and American daily news. Content in too many forms. Born from an impetuous whim only a billionaire would call a business plan, the paper quickly began its operations, grabbing all of the talent money could buy. Frank Deford, a writer who had achieved legendary status by the age of 50, was made editor-in-chief; columnists and a feature staff were gathered, poached, and lured from everywhere; every beat in the athletic spectrum was covered, charted, and ranked, from golf to professional wrestling.

"I've posted to YouTube a series of 22 short videos giving an introduction to quantum computing. Here's the first video:

Below I list the remaining 21 videos, which cover subjects including the basic model of quantum computing, entanglement, superdense coding, and quantum teleportation.

To work through the videos you need to be comfortable with basic linear algebra, and with assimilating new mathematical terminology. If you're not, working through the videos will be arduous at best! Apart from that background, the main prerequisite is determination, and the willingness to work more than once over material you don't fully understand.

In particular, you don't need a background in quantum mechanics to follow the videos."

"Clearly energy is an important topic. We all like to live with stuff that uses energy: driving, computers, the internet, lights, heating and cooling. So, where does all our energy come from?"

"It doesn't matter how much I sequester myself or how thrilling the event is -- if I know the game has finished, it's difficult to sustain authentic interest in what I've recorded. I inevitably fast-forward to the last two or three minutes (even when I have no vested interest in the outcome). Since I'm watching the game purely for entertainment, it shouldn't be any different from the real thing. It should, in fact, be better, just as it's more enjoyable to watch self-recorded episodes of Frontline or Storage Wars or any other traditional show that lives inside my DVR. In theory, I should be able to enjoy every single game I want to see, on my own schedule -- all I need to do is avoid the Internet for a few hours and not glance at the ESPN ticker on public TV screens. But it never works: I get home, I start watching the recent past, and I find myself rushing toward the present.

So why is this?"
