The Brain—Information about the Brain 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. It is vital to our existence. Our brains enable us to think, as René Descartes so skillfully pointed out nearly 400 years ago. The brain makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we consume. Scientists have worked for many years to unravel the complex workings of the brain. Despite these and other significant advances in the field of brain research, most of the processes responsible for the integrated functioning of billions of brain cells remain a mystery. An essential aspect of any scientific research is communicating results to the public in a way that is easily understood. To correctly interpret the information transmitted through these venues, we need a better understanding of basic concepts related to the brain. 2 Myths and Realities about the Brain Figure 1.

Boss Gif – Swim Like A Dolphin In The Sea, Edition! « Anguished Repose "My friend.--Welcome to the Carpathians. I am anxiously expecting you. Sleep well tonight. 4 May--I found that my landlord had got a letter from the Count, directing him to secure the best place on the coach for me; but on making inquiries as to details he seemed somewhat reticent, and pretended that he could not understand my German. This could not be true, because up to then he had understood it perfectly; at least, he answered my questions exactly as if he did. He and his wife, the old lady who had received me, looked at each other in a frightened sort of way. Just before I was leaving, the old lady came up to my room and said in a hysterical way: "Must you go? "Do you know what day it is?" "Oh, yes! On my saying that I did not understand, she went on: "It is the eve of St. It was all very ridiculous but I did not feel comfortable. I tried to raise her up, and said, as gravely as I could, that I thanked her, but my duty was imperative, and that I must go.

Scientists Create Material More Insulating than the Vacuum (PhysOrg.com) -- With its complete lack of atoms, a vacuum is often considered to be the best known insulator. For this reason, vacuums are regularly used to reduce heat transfer, such as in the lining of a thermos to keep beverages hot or cold. However, in a recent study scientists have found a material even less able to conduct heat: a stack of photonic crystals layered within a vacuum can create a material with a thermal conductance just half that of empty space alone. Basically, heat can be transferred from one material to another in three main ways: convection, conduction, and radiation. Shanhui Fan of Stanford University and his colleagues wondered if any material could block infrared radiation better than a vacuum can. The scientists found that a 100-micron-thick structure made of a stack of 10 photonic crystal layers, each 1 μm thick and separated by 90-μm gaps of vacuum, could reduce the thermal conductance to about half that of a pure vacuum.
