Applications of ideas from physics to study situations in biology are not new. Pauling, Crick and Watson and other scientists right from Einstein had been applying physics to solve biological problems. However, since The structure of the genes was studied by X-rays, a host of the latest applications ranging from electron microscopy, NMR, ESR to laser and fibre optics have become quite common to study medical problems, Quantum theoretical applications are new to biology. Electrons moving through a green leaf as well as a green sulphur bacterial bloom have been observed to be effectively performing a quantum "random walk to seek the optimum path to solar energy. A parallel can be sought in the "random walk" of the conduction electrons choosing a particular path in an integrated circuit changing according to conditions- After all Einstein's earlier work was on Brownian motion.
