Donald E. Knuth talks about New The Art of Computer Programming Book Chapter

Donald E. Knuth Talks about SAT SolversIn his latest talk about SAT solvers at the Johannes Kepler University Linz (JKU), Computer Science pioneer Donald E. Knuth gave a deep and quite emotional insight about his life-long, epic work on the book ‘The Art of Computer Programming’. The Art of Computer Programming, aka TAOCP  represents the one and only global reference on algorithms, their analysis and computer programming in general and is the standard work for all computer scientists worldwide.

Donald E. Knuth talked about his recent chapter within TAOCP on SAT solvers and how fascinating these satisfiability problems as well as the derived problem and number patterns are. Knuth invited the audiance to ask all kind of questions, which span detailed explanaitations on his love for TEX as well as for his CWEB language, to quite personal topics, such as Prof. Knuth’s love for organ music and that he might also write down his own organ composition. During his trip through Austria, Prof. Knuth also had the chance to play on famous local organs, such as the organ within the monastry of St. Florian where Anton Bruckner was playing in 1850.

To summarize, Prof. Knuth gave a fascinating and very inspiring talk about his actual work and it seems as if there will be a lot of topics and chapters within the coming years!

He also shared an interesting advice with his audience: “If you are not fascinated and interested in what you are doing, then you are the only person to blame for!”


Arduino Tutorial Video: How to design a motorized Pinwheel

In his latest Arduino tutorial video, Massimo Banzi explains how to control a motorized pinwheel without damaging your Arduino board. As DC motors can generate power spikes, that can damage electronic circuits, Massimo Banzi explains how to use a diode to overcome this issue. A DC motor works at a higher voltage than the Arduino. This means that it requires more current that an Arduino pin can provide. Within this video tutorial Massimo will also explain how to provide enough current to drive the DC motor.

TED: Daphne Koller speaks up for a revolution in online education

Daphne Koller is asking top universities, such as Stanford, to put their courses online for free, but not just as a service, but as a way to research how people learn. She tries to discover how knowledge is processed and absorbed by her audience, through tracking each keystroke, asking comprehension quiz and peer-to-peer forum discussion.

Daphne Koller is bringing courses from top colleges online, free for anyone who wants to take them. Her Website already has an impressive number of online students who follow her courses. Daphne Koller is working as a Stanford professor and founded her startup Coursera for sharing online courses.

She follows the same vision Peter Norvig has already presented before in his amazing TED talk on his experiences with his 100.000 student classroom on modern approaches of artificial intelligence last year.

Engineer Guy vs. The Microwave Oven

In his new video tutorial Bill the Engineer Guy explain the anatomy of a basic microwave oven, then come through with a great, memorable visualization that intuitively links the wave’s oscillating electric and magnetic fields to the rotational vibrations of water molecules, in the food, that actually heat it up. Other highlights include mapping the standing wave in the cooking cavity by heating a platter of grated cheese, and a cross-section of a real magnetron with overlays and a handy analogy explaining how it works.

TED Talk by Massimo Banzi – Inventing things with Arduino

Massimo Banzi one of the inventors of THE electronics prototyping system called Arduino spoke at TEDGlobal 2012 about the cool things people are making with Arduino. At the moment Arduino is one of the most popular prototyping platforms worldwide. Some weeks ago Massimo Banzi presented their new Arduino package design at the Maker Faire and he got a lot of interested people around him. The usability of the Arduino system is that good that even children are developing their first electronics project with it. And with a price around 20€ its definitely cheaper than the traditional PIC microcontroller programming enviroments i used.

The world needs young Scientists

View E.O.Wilson’s TED talk in which he states that the world badly needs young scientists. Previewing his upcoming book, he gives advice collected from a lifetime of experience — reminding us that wonder and creativity are the center of the scientific life. Biologist E.O. Wilson explores the world of ants and other tiny creatures, and writes movingly about the way all creatures great and small are interdependent.

In the attempt to make scientific discoveries, every problem is an opportunity — and the more difficult the problem, the greater will be the importance of its solution.” (E.O. Wilson)

Blue Economy: Sustainable Business and Entrepreneurship


Some days ago i heard an interesting interview with Gunter Pauli, one of the founders of Blue Economy. Gunter Pauli is running active businesses, is author of several books, including educational children stories and evangelist of a new way of doing business, called Blue Economy. One of Pauli’s first books was a biografy of Aurelio Peccei, one of the founders of the Club of Rome, which assistant Pauli was between 1979 to 1984. What he discussed in this interview was the impact of Blue Economy and how this new concept can solve the economic challenges and problems we see today. He argues that the way we are learning to do business today is driven by two major approaches Macroeconomics and Microeconomics, which were invented before World War II. He also argues that these two approaches are no longer adequat for our globalized markets today, which are full of technological possibilities.

It was good to hear that a crowd of smart people are believing that there are more positive directions beyound the actual chaos of our worldwide economic crisis.

In his TED talk, SETI researcher Seth Shostak bets that humans will find extraterrestrial life in the next twenty-four years, or he’ll buy you a cup of coffee. At TEDxSanJoseCA, he explains why new technologies and the laws of probability make the breakthrough so likely — and forecasts how the discovery of civilizations far more advanced than ours might affect us here on Earth. Seth Shostak is known as an astronomer, alien hunter and bulwark of good, exciting science.

Engineering Guy explains ‘How a laser works’

Many modern technologies, such as range finders, CD and Blueray players and even barcode scanners depend on lasers. The unique characteristics of laser light make all these things possible. In 1960, Ted Maiman demonstrated the first laser by taking a cylinder of ruby and surrounding it with a xenon arc flash lamp used in aerial photography. But do we really know exactly how laser technology works? Another interesting lession with the Engineering Guy William (Bill) S. Hammack will fill this knowlege gap for sure 🙂
