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
Nobel laureate Sir Paul Nurse tells the story of another great idea in biology – genes as the basis of heredity – in a lecture at the Royal Institution in London. It all started with the gardening monk Gregor Mendel and his peas in the 19th century and reached a key milestone with the unravelling of the molecule of heredity, the DNA double helix, by James Watson and Francis Crick in 1953
The great ideas of biology covered are
- the cell
- the gene
- natural selection
- Life as chemistry
- Biology as an organized system.
Similarly to “A Brief Introduction to Genetics” David Murawsky (as mentioned around here before, but hey, they repeat stuff on TV all the time, and not only the goodies) put another impressive clip out there: “18 Things You Should Know About Genetics“. Enjoy!
As said before, I am getting deeper into graph-databases, specifically “neo4J “. The pace of development is breathtaking, it’s hard to keep up with the new versions and amazing features. In preparation of attending a “Cypher Hands On” (Meetup-Graph), I finally got round to updating to the latest 1.8M03 Milestone. By now, there are a couple of nice introductory videos available:
You might want to check out the videoGraphy @ neo4J. I also recommend the following Intro to Graph Databases (on vimeo) which has a nice explanation on what the buzz/whole point is all about plus some real world examples and history:
To deepen our understanding of the graph-theoretic foundations, I came across these books via blog.postmaster.gr:
“Graph Theory and Complex Networks: An Introduction” by Maarten van Steen. It is very interesting to note that this book is also available electronically as a personalised PDF. As the author notes: “When you write a book containing mathematical symbols, thinking big and acting commercially doesn’t seem the right combination. I merely hope to see the material to be used by many students and instructors everywhere and to receive a lot of constructive feedback that will lead to improvements. Acting commercially has never been one of my strong points anyway”.
– Reinhard Diestel: “Graph Theory“.
It is fun, indeed. Enjoy!
Google started to roll out the Knowledge Graph, intended to be more about things rather than just strings. Delivering and disambiguating related content based on semantic network associations sounds great, if this really is a step forward to move out of the filter-bubble remains to be seen. Overall, it seems to be related to the idea of a conceptual graph, and wikipedia forms a big chunk of the underlying knowledge-base.

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.
In case you wondered (like me) who is doing that awesome tune used in the M$-IE-TV-ad: It’s ALEX CLARE with “TOO CLOSE”.
For several years I’ve been a big fan of Top Gear – the guys have been entertaining my inner child. Seen rationally, the petrol-based internal combustion engine is a dead end, but getting from A to B is hardly the point, or is it? I like the irreverent, playful and fun approach to how things actually work – by taking them apart, blowing them up or whatever else seems suitable – they have an immense imagination in that department. You know, what distinguishes the men from the boys is the size of their toys. In this regard, the top gear presenters are the real grown-ups, thinking big and out of the box. Some of their projects on science and engineering are among my all-time favourites, so I am happy to see Richard “Hamster” Hammond back on the screen again.
First, there’s the recently launched “Crash Course” :
And then I have to mention his series “Engineering Connections” on the National Geographic Channel where Hammond
looks at how engineers and designers use historic inventions and clues from the natural world in ingenious ways to develop new buildings and machines.
And if you still can take some more, there is some really stunning footage in the “Invisible worlds” – series (2010). Definitely something to go into my DVD collection, here’s a teaser:
