Beautiful Chemistry trailer

This is something I’ve wanted to do for many years, which we discussed when I was at the Royal Institution but never quite got around to: careful macrophotography of chemical phenomena and reactions.

The Institute of Advanced Technology at the University of Science and Technology of China and Tsinghua University Press have teamed up with photographer and science visualisation specialist Yan Liang to film a series of reactions, and from the looks of this trailer they’ve made a really good job of it. There’s a ‘Beautiful Chemistry’ project website and blog, and I suspect I’ll be posting again when the main project goes live next month.

Extracting audio from video. Without a microphone.

We’ve all winced at those scenes in CSI:Nowheresville when somebody in a lab coat ‘enhances’ an image until you can see the reflection of the room in the pupil of somebody’s eye, or whatever.

This video is like that. Clearly implausible, most likely witchcraft.

Alternatively, a group of researchers at MIT really have found a way of extracting temporal information from CMOS sensor skew, sufficient to reconstruct audio up to around the 400Hz range from pictures alone.

Damned impressive, even if ‘sorcery’ is a more plausible algorithm.
