Louis Braille, the inventor of the reading and writing system for the blind, was born exactly 200 years ago. I listened to an inspiring BBC podcast about him this morning. His genius was such that the system is used today unchanged, and allows the blind to read at some 120 words per minute. Braille invented his system at the age of 15, and died by the age of 43 of tuberculosis. Continue reading ‘Mathematics for the blind’

Second time I have been amazed with technology today! This is a clever ad for a mini. The magazine has a bold black and white pattern of circles. You go to a web page (in German), switch on your webcam and hold the magazine (or a print of the pattern from the web site) in front of the webcam. Continue reading ‘Amazing interactive 3D display’
Take a look at this:
What is special about it? Well, it is made automatically from a 3D computer model, using a 3D printer. That’s right, a printer that produces a 3D object. These have been around for a long time, often called “rapid prototypers”, but have been very expensive. At last they are becoming affordable. This “print” is a sample kindly given to me by Remco Hosman who has just started a bureau service for printing in Amsterdam. Continue reading ‘3D printer’
After the one day holography conference yesterday, I and others have a feeling holography is bouncing back. I can’t put a finger it, but there is definite interest from museum and gallery folk, and there is an air of confidence amongst holographers. I have not seen this in the last 20 years. Let’s hope it continues. We might have some exciting times ahead. Picture shows Jonathan Ross inaugurating the conference. Seated in the front row are Graham Saxby and Martin Richardson.

I have been waiting for years to see the holograms of Yves Gentet. He gave a talk this morning at the conference in Leicester and showed several of his holograms. I was absolutely amazed. He has set the standard for colour holography. Just take look at these holograms.
The “saint” hologram is actually digitally produced using a printer that Yves himself has developed.
