Physicists Finding Perfection...in Biology June 1, 2009 Biologic Staff When we think of simple, elegant, unifying principles in science, we think of physics. It’s not surprising then that physicists who examine living systems are looking for principles of this kind.And it seems they have found one. Simply stated, it is that biological processes tend to be optimal in cases where this can be tested. Life’s complexity can make it hard to pinpoint what “optimal” means, but sometimes physical limits provide a crisp definition. Because these limits cannot possibly be exceeded, they serve as an objective standard of perfection. Interestingly, in...
