Illustration from De Homine by Rene Descartes Featured 6 Jan 2004 Print

Illustration from De Homine by Rene Descartes

Illustration from a book by Rene Descartes De Homine, published after his death in 1662. It is regarded as the first textbook of physiology. The picture shows the supposed relationship between the sensory perception of an image & muscular action. The image is relayed from the eyes to the pineal gland (H). The reaction between the image & the pineal gland determines the motor action, driven from c. Descartes concludes that "the relationship between b (reception of the signal) & c (action) is an insoluable mystery, wrapped up in the very nature of the soul". Descartes, a French philospher & mathematician, lived from 1596-1650

Water on Mars in its past Featured 6 Jan 2004 Print

Water on Mars in its past

Water on Mars. Image 2 of 4. Artwork of water and clouds on Mars billions of years ago. It is thought that liquid water existed on Mars early in its history, but was lost to space over time. This may have been due to Mars weak gravity, thin atmosphere and weakening magnetic field. If liquid water did exist on Mars, there is the possibility that life may have begun there. Numerous probes have so far failed to find any evidence for this, however. In the future, it may be possible to return Mars to this wet state artificially, and create an environment suitable for life once again. This process is called terraforming. For a sequence of Mars drying, see images R350/214-217

Iris scanning Featured 6 Jan 2004 Print

Iris scanning

Iris scanning. Conceptual computer artwork of the scanning of a human eye. Iris scanning images the iris, the coloured part of the eye, which is unique in each individual. A computer divides the iris scan into areas from which it recognises unique iris features. The data can then be used to identify the individual if the eye has been previously scanned. Alternatively, this image may represent surveillance of computer use
