Musique et images fractales ; tout un monde à découvrir. Lire à nouveau le Gödel, Escher, Bach : Les Brins d'une Guirlande Éternelle (1979) de Douglas Hofstadter ?...

[VIDEO] Shrinking Glaciers—A Chronology of Climate Change

Analysis of Earth's geologic record can reveal how the climate has changed over time. Scientists in New Zealand are examining samples from the rocky landscape once dominated by glaciers. They are employing a new technique called surface exposure dating, which uses chemical analysis to determine how long minerals within rocks have been exposed to the air since the glaciers around them melted. Comparisons of this data with other climate records have revealed a link between glacial retreat and rising levels of carbon dioxide in the air, findings that are informing scientists' understanding of global climate change today.

Ramesh Raskar: Imaging at a trillion frames per second, so detailed it shows light itself in motion.

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.

[VIDEO] Michio Kaku: The Universe in a Nutshell

What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

Daniel Tammet - The Boy With The Incredible Brain

Tammet has been "studied repeatedly" by researchers in Britain and the United States, and has been the subject of several peer-reviewed scientific papers.Professor Allan Snyder at the Australian National University has said of Tammet: "Savants can't usually tell us how they do what they do. It just comes to them. Daniel can describe what he sees in his head. That's why he's exciting. He could be the 'Rosetta Stone'

to science." In his mind, he says, each positive integer up to 10,000 has its own unique shape, colour, texture and feel. He has described his visual image of 289 as particularly ugly, 333 as particularly attractive, and pi as beautiful. The number 6 apparently has no distinct image yet what he describes as an almost small nothingness, opposite to the number 9 which he calls large and towering. Tammet has described 25 as energetic and the "kind of number you would invite to a party". In his memoir, Tammet states experiencing a synaesthetic and emotional response for words and numbers, but not letters in algebraic contexts.

 

Tammet holds the European record for reciting pi from memory to 22,514 digits in five hours and nine minutes on 14 March 2004. Tammet has reportedly learned 10 languages, including Romanian, Gaelic, Welsh, and Icelandic which he learned in a week for a TV documentary.

Comprehensive Virology University Class (26 hours of VIDEO lectures)

Virology - Biology W3310 and W4310

 

The basic thesis of the course is that all viruses adopt a common strategy. The strategy is simple:

 

1. Viral genomes are contained in metastable particles.

2. Genomes encode gene products that promote an infectious cycle (mechanisms for genomes to enter cells, replicate, and exit in particles).

3. Infection patterns range from benign to lethal; infections can overcome or co-exist with host defenses.

 

The course will emphasize the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycles, the interactions of viruses with host organisms, and how these lead to disease are presented with examples drawn from a set of representative animal and human viruses, although selected bacterial viruses will be discussed.
