A message from space to our blue marble:
And here is the executive summary: “Our Story in 1 Minute” (somewhat reminiscent of the BigBangTheory Intro Sequence) by melodysheep
Not that he won’t mind it was already yesterday. Since there are a couple of posts related to him on this site there is probably no need re-iterate how inspirational he was and even over 2 decades after his death still is. Just a welcome occasion to point out richard-feynman.net which has a great collection of videos, a photo gallery and quotes like this one on the ignorance of experts:
Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers in the preceding generation … Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts…
Let me refer you to this post with a bit more physics in it while leaving you with this scene from the movie “Infinity”, showing Feynman at the tender age of 6 learning a few things about science from his father.
Pearl‘s book on “Causality” has been on my shelf for a while now. I also read it, a few times, but never managed to get through it in one go, cover to cover. Consequently, I haven’t come to grips with all details, implications and equations yet. No reason to worry about my intellectual capabilities, it’s quite fundamental and takes time to sink in. Now Judea Pearl has been awarded the 2011 ACM Turing Award – Congratulations!
The annual Association for Computing Machinery (ACM) A.M. Turing Award, sometimes called the “Nobel Prize in Computing,” recognizes Pearl for his advances in probabilistic and causal reasoning. His work has enabled creation of thinking machines that can cope with uncertainty, making decisions even when answers aren’t black or white. […]
The UCLA computer science professor is widely credited with coining the term “Bayesian Network,” which refers to a statistical model ACM describes as mimicking “the neural activities of the human brain, constantly exchanging messages without benefit of a supervisor.” Bayesian networks have been used to, among other things, analyze biological data for studies of medicine and diseases.
Here is a chance to see him talk for yourself:
“I compute, therefore I understand” – More videos are here on theScienceNetwork.

There is this old story of the 3 wise blind guys who come to examine an elephant. They are lead up to it, and one of them gets to grab the ear, another the holds on to a tusk, and the third gets hold of the tail.
Later, they come to completely different opinions about the nature of the object under study – is it flat and flappy, thin and wriggly, or hard and pointy? And, obviously, later they spend a looong time arguing and beating each other up about their theories on what it really is like.

The pictures of the anisotropy of the cosmic microwave background radiation have been fascinating me since looking deeper into the relative spatial distribution of residue contacts in proteins and complexes. Now here is a beautifully produced documentary by the BBC that takes you to the edge of the universe and everyting else we know about – well – mostly nothing :

Via the Cambridge University Alumni Group I was made aware of the forthcoming event “Free Radicals: The Secret Anarchy of Science” at the Real Time Club Dinner on the 21st of June from 18:00 to 21:00 at the National Liberal Club, Whitehall Place, SW1A 2HE. You do not need to be a member of the club to attend this event: see http://bit.ly/iE5Hc8.
The speaker is Michael Brooks – an English scientist and author. It promises to be quite an interesting event, especially since Brooks takes a strong stance against political representatives of pseudo-science – more from him about himself can be found at http://www.michaelbrooks.org/.
