Imagine you’ve got 5 masses connected to each other by springs and subjected to Brownian thermal perturbation, wobbling around, what is the probability distribution of their displacements y1 from y5? Well, you can work it out, and their inverse covariance matrix (K-1) is to do with who’s connected by springs. Each term in the energy gives you terms in this matrix, describing the couplings between these displacements: so the inverse covariance matrix is very sparse, very […]

10:34 PM | How alien cell membranes could form in methane seas
What might aliens look like? If Star Trek is to be believed, they would mostly look like jobbing actors with plasticene on their faces. But the environment which enabled a warm-blooded, two-legged ape to become the alpha organism is very specific to Earth – a myriad of different creatures could evolve on planets with a…

“Educators, generals, dieticians, psychologists, and parents program. Armies, students, and some societies are programmed. An assault on large problems employs a succession of programs, most of which spring into existence en route. These programs are rife with issues that appear to be particular to the problem at hand. To appreciate programming as an intellectual activity in its own right you must turn to computer programming; you must read and write computer programs—many of them. […]

6:20 AM | How photosynthesis is inspiring solar power research
SUMMARY: To meet humanity’s growing energy demands, scientists are taking lessons from plants, which perfected the process of capturing the sun’s rays and transforming that into starch. Might scientists be able to adapt the photosynthetic process pioneered by plants and adapt it to meet human demands? The impacts that people have upon the global environment has been a concern to scientists for more than 100 years. These impacts are due, in large part, to the fuels we use. To […]

“There are no algorithms or mathematics in the book. Most previous books start out at the layer of algorithms and work their way up. As a result, they don’t really have enough room to talk about the full suite of design choices. A lot focus much more either on information visualisation or scientific visualisation—that is, on abstract data or on spatial data—and they don’t really emphasise the way that they’re both visualisation.” - ~ 21m into an […]
