51William James Sidis — (April 1, 1898 ndash; July 17, 1944) was an American child prodigy with exceptional mathematical and linguistic abilities. He first became famous for his precociousness, and later for his eccentricity and withdrawal from the public eye. He… …
52Tape head — For the album by King s X, see Tape Head. A tape head is a type of transducer used in tape recorders to convert electrical signals to magnetic fluctuations and vice versa. Contents 1 Principles of operation 1.1 Reversibility 1.2 Head g …
53Spirometry — TLC Total lung capacity: the volume in the lungs at maximal inflation RV Residual volume: the volume of air remaining in the lungs …
54Irreversibility — In science, a process that is not reversible is called irreversible. This concept arises most frequently in thermodynamics, as applied to processes. Irreversibility is also used in economics to refer to investment or expenditures that involve… …
55Receptor antagonist — This article is about the biochemistry term. For other uses, see Antagonist (disambiguation). Antagonists will block the binding of an agonist at a receptor molecule, inhibiting the signal produced by a receptor agonist coupling. A receptor… …

57Glass electrode — A glass electrode is a type of ion selective electrode made of a doped glass membrane that is sensitive to a specific ion. It is an important part of the instrumentation for chemical analysis and physico chemical studies. In modern practice,… …
58Nitroaldol reaction — The Henry Reaction (also referred to as the nitro aldol reaction) is a classic carbon–carbon bond formation reaction in organic chemistry. Discovered in 1895 by L. Henry, it is the combination of a nitroalkane and an aldehyde or ketone in the… …
59GIK — The Great Invention Kit (or GIK) is a construction kit, like Lego, but using a different type of assembly principle. It was first developed by Grace and Eli and Neil Gershenfeld at the MIT Media Lab.Two GIK parts are assembled by turning one of… …
60History of entropy — The concept of entropy developed in response to the observation that a certain amount of functional energy released from combustion reactions is always lost to dissipation or friction and is thus not transformed into useful work . Early heat… …
