How to use technology to teach undegraduate biology
Explanations by Stony Brook U. professor William Collins: it was fun to watch for me. The video brings up a lot of great points that would be useful for college degree courses online to implement. Technology will surely be an important addition to all college courses in the future.
Lithium problem
Apart from being a very nice review of Big Bang Nucleosynthesis (BBN), recent paper by Karsten Jedamzik and Maxim Pospelov discusses an important open problem in the physics of BBN. In short, the lithium problem in physics of Big Bang Nucleosynthesis is seeming underproduction of . What do we mean by that? Well, the lithium [...]
Michio Kaku on artificial intelligence
Nowadays, it is fashionable to hypothesize that an advanced AI, when it appears, will wipe pathetic humans out of the face of the Earth (risk of unfriendly AI, as transhumanists like to call it). I think, what’s not taken into account in these considerations is that humans will evolve as well, will be willing to [...]
How might one design a nano-machine?
Significant advances in laboratory techniques in tailoring and processing materials at the atomic level have resulted in nanotechnology becoming an increasingly mature field. One of the exciting goals of nanotechnology is the design of powerful nano-machines, i.e. functional entities at the nano-scale that work like macro-world machines. A simple nano-machine would be an entity that [...]
Vorticity generation in cosmological perturbation theory
Adam Christopherson is a PhD student at Queen Mary, U. of London working with Karim Malik on cosmological perturbation theory. Dmitry. In this blog post, I will summarize recent work on vorticity generation in cosmological perturbation theory, undertaken by Karim Malik, David Matravers and myself. The main result of the paper this is based on, [...]
Average life expectancy or more on data visualization
In continuation of my series of posts about data visualization (Dynamical maps and Gapminder), let me show you today another cool resource: interactive map of the world StatPlanet. Here is for example a map showing average age in different countries (data from 2006): Russia seems to be rather mature country on this map – average [...]
A bound on the speed of sound from holography?
This post is authored by Aleksey Cherman (on the left) and Abhinav Nellore (on the right). Aleksey is a graduate student in the nuclear theory group at the University of Maryland, College Park, working with Tom Cohen, and Abhi is a graduate student in Steve Gubser’s group at Princeton. Dmitry. We all know that sound [...]
Nanotechnology for fun and profit: video of the day
This is a 50 min lecture about new nanotechnologies (carbon nanotubes, in particular) by Ray Baughman given at Carnegie Mellon U. As you may know, Russian government plans starting large scale investing into nanotechnology and have already organized a company (Rusnano, formely Rosnanotech) to channel government investments. The head of the company is Anatoly Chubais, [...]
Self-improving artificial intelligence: video of the day
A lecture (colloquium, more precisely) by Steven Omohudro given at Stanford. If you don’t know about the lecturer, the guy has had quite an impressive career: he started as theoretical physicist, but switched eventually to AI and neural networks (among may other achievements on this field, he held an assistant professorship at U. of Illinois [...]
383. Puzzling kinetics of Bose-Enstein condensation
Just finished reading a really review “Magnon BEC and spin superfluidity” by Yu. Bunkov and G. Volovik, which left me with quite a bit of material to think about… Probably the thing that stroke me most after digesting the review is how poorly I (or in truth – it’s better to say “we”) actually understand [...]
