“I was taking an advanced calculus class and my instructor was reputed to be a fabulous researcher, but he barely spoke English. He was a very boring and bad teacher and I was absolutely lost and in despair.
So I went to the campus tutoring centre and they had Betamax tapes of a professor who had won teaching awards. Basically I sat with those tapes and took class there. But I still had to go to the other one and sat there and wanted to kill myself.
I thought at that time, in the future, why wouldn’t you have the most entertaining professor, the one with the proven track record of getting knowledge into people’s heads?
We’re still not quite there. In university you’re still likely to be in a large lecture hall with a very boring professor, and everyone knows it’s not working very well. It’s not even the best use of that professor’s time or the audience.”

"The cities are currently responsible for 75% of the worldwide consumption of energy and they reject 80% of worldwide emissions of CO2. The contemporary urban model is thus ultra-energy consuming and works on the importation of wealth and natural resources on the one hand, and on the exportation of the pollution and waste on the other hand. This loop of energetic flows can be avoided by repatriating the countryside and the farming production modes in the heart of the city by the creation of green lungs, farmscrapers in vertical storeys and by the implantation of wind and solar power stations. The production sites of food and energy resources will be thus reintegrated in the heart of the consumption sites ! The buildings with positive energies must become the norm and reduce the carbon print on the mid term."
"Bitcoin really is a tiny market in the scheme of things, and its recent gyrations mean that the dollar, euro and yen have nothing to fear from the competition. If a currency can lose 75 percent of its buying power in two days, it may not be the best store of value. But it also an important window into the strange and uncomfortable mystery of “What is money,” which is a harder question to answer than one might think."
A submarine cable is about 0.75 to 2.5 inches in diameter, or about the thickness of three ordinary garden hoses. The longest cable, called the Southern Cross, runs under the Pacific, stretching 18,500 miles.
"We needed to find a graphic style to communicate the beauty and intricacy of DNA. We wanted to create nostalgia; taking the audience back to the days of textbook diagrams and old science documentaries, such as Carl Sagan's COSMOS and IBM’s POWER OF TEN (1977). Using the double helix circular theme as a core design we focused on form, movement and colour to create a consistent flow to the animation, drawing on references from nature, illustrating how DNA is the core to everything around us."
"Ever since I created the first version of this video a year ago I've been wanting to try it again with more water and better lighting / footage. This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.
Sure, a 3-D printed car is cool, but it doesn’t go to space. And there’s probably a good reason for that, but now a competition is aiming to launch the newest manufacturing fad into the final frontier by challenging people to design 3-D printed rocket engines.
"I made these custom ‘mistake’ keys for my keyboard… Solid gold Command and Z keys. The ones we are constantly pressing to go back in time."
