Art of Schrodingers Cat experiment

Schrodinger's Cat. Computer artwork depicting the famous "Schrodinger's Cat" thought experiment. The image shows a cat both dead (grey) and alive (ginger) inside a box on a starfield background. The orbitals of a radioactive isotope are superimposed over the cat. In this hypothetical situation, the cat is thought to be both alive and dead until observed. This is because a quantum event (the decay of a radioac- tive particle) is set up to trigger the release of a lethal poison from a vial (not seen here) that kills the cat. According to quantum physics, the unstable particle exists in an intermediate "probabilistic" state until it is observed

Computer screen showing a human genetic sequence

DNA sequencing. Computer screen showing a sequence of base pairs forming part of the human genetic code. The three billion base pairs that form the genetic code of human DNA (deoxyribonucleic acid) are collectively known as the human genome. Each of the coloured bands represents the position of one of the four nucleotide bases that form the code. As each person's genetic code is unique this sequence is called a DNA fingerprint. Photographed at the Joint Genome Project (JGI), part of the Human Genome Project, in Walnut Creek, California, USA
