Professor Randy Pausch, well-known for his highly motivating Last Lecture, passed away yesterday morning.

If you’ve not seen his video, “Randy Pausch Last Lecture: Achieving Your Childhood Dreams” …

Feeling in this moment, I want to say, with all my heart, to those that I know and those that I don’t know yet, “I love you”. Would you plant these three words forward today, ensure they are placed in the sun, and continue to water them.

‘In this fiery and funny talk, New York Times food writer Mark Bittman weighs in on what’s wrong with the way we eat now (too much meat, too few plants; too much fast food, too little home cooking), and why it’s putting the entire planet at risk.’

‘Ocean explorer Robert Ballard takes us on a mindbending trip to hidden worlds underwater, where he and other researchers are finding unexpected life, resources, even new mountains. He makes a case for serious exploration and mapping. Google Ocean, anyone?’

‘While in Asia in 2007, TEDster Paul Koontz got the priceless chance to spend a few days in North Korea. He brought his two kids — and his camera, capturing both quotidian detail (like the military bearing of a lonely traffic warden) and the grand spectacle leading up to the Mass Games. It’s a rare perspective on a culture we know far too little about.’

‘Johnny Lee demos his amazing Wii Remote hacks, which transform the $40 game piece into a digital whiteboard, a touchscreen and a head-mounted 3-D viewer. A multi-ovation demo from TED2008.’

‘In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe — How did the universe begin? How did life begin? Are we alone? — and discusses how we might go about answering them.’

‘In Al Gore’s brand-new slideshow, he presents evidence that the pace of climate change may be even worse than scientists were recently predicting, and challenges us to act with a sense of “generational mission” — the kind of feeling that brought forth the civil rights movement — to set it right. Gore’s stirring presentation is followed by a brief Q&A in which he is asked for his verdict on the current political candidates’ climate policies and on what role he himself might play in future.’

‘Architect Norman Foster discusses his own work to show how computers can help architects design buildings that are green, beautiful and “basically pollution-free.” He shares projects from throughout his career, from the pioneering roof-gardened Willis Building (1975) to the London Gherkin (2004). He also comments on two upcoming megaprojects: a pipe to bring water from the Red Sea to the Dead Sea, and the new Beijing airport.’

‘Neuroscientist and inventor Christopher deCharms demos an amazing new way to use fMRI to show brain activity while it is happening — emotion, body movement, pain. (In other words, you can literally see how you feel.) The applications for real-time fMRIs start with chronic pain control and range into the realm of science fiction, but this technology is very real.’

‘Clifford Stoll could talk about the atmosphere of Jupiter. Or hunting KGB hackers. Or Klein bottles, computers in classrooms, the future. But he’s not going to. Which is fine, because it would be criminal to confine a man with interests as multifarious as Stoll’s to give a talk on any one topic. Instead, he simply captivates his audience with a wildly energetic sprinkling of anecdotes, observations, asides — and even a science experiment. After all, by his own definition, he’s a scientist: “Once I do something, I want to do something else.”‘
