Introduction Albert Einstein said quotThe most incomprehensible fact about nature is that it iscomprehensible.quot Indeed physical phenomena are comprehensible.Weather changes chemicalreactions and molecular structures appear quite complex but their underlying principles areamazingly simple. All physical phenomena are governed by four fundamental forces - gravityelectromagnetism strong and weak nuclear forces. Recently these forces can further be unifiedby a single theory -- the string theory. What about the brain Is its ability of comprehension comprehensible In the seventeenthcentury Isaac Newton had discovered the gravitational law and Robert Boyle had formulated theequation for gas properties but human beings were still quite ignorant about physiologicalsystems. William Harvey a pioneer in blood circulation told Robert Boyle that it was thevalves in the veins which guided him to the next phase of his thinking. We now know that thoughts are not controlled by blood vessels and sorrow has nothing to do witha quotbroken heartquot. They come from our brain -- the only thing which can try to understanditself. With a size smaller than a microwave oven our brain contains more than 10 billions ofneurons. Each neuron is connected to many up to thousands other neurons.
