The Sears–Haack body is the shape with the lowest theoretical wave drag in supersonic flow, for a slender solid body or revolution with a given body length and volume. The mathematical derivation assumes small-disturbance (linearized) supersonic flow, which is governed by the Prandtl–Glauert equation. The derivation and shape were published ...
Body hacking. Body hacking is the application of the hacker ethic (often in combination with a high risk tolerance) in pursuit of enhancement or change to the body's functions through technological means, such as do-it-yourself cybernetic devices [1] or by introducing biochemicals. [2]
Bioelectrical impedance analysis. Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
The Hacker's Diet (humorously subtitled "How to lose weight and hair through stress and poor nutrition") is a diet plan created by the founder of Autodesk, John Walker, outlined in an electronic book of the same name, that attempts to aid the process of weight loss by more accurately modeling how calories consumed and calories expended actually impact weight.
Electrical impedance myography, or EIM, is a non-invasive technique for the assessment of muscle health that is based on the measurement of the electrical impedance characteristics of individual muscles or groups of muscles. The technique has been used for the purpose of evaluating neuromuscular diseases both for their diagnosis and for their ...
Power supply. 4 AAAs, 1 CR1616 or CR1620. The TI-82 is a graphing calculator made by Texas Instruments. The TI-82 was designed in 1993 as an upgraded version of and replacement for the TI-81. [1][2] It was the direct predecessor of the TI-83. It shares with the TI-85 a 6 MHz Zilog Z80 microprocessor. Like the TI-81, the TI-82 features a 96×64 ...

The chronaxie values for mammalian ventricles at body temperature range from 0.5 ms (human) to 2.0 to 4.1 ms (dog); this is an 8.2/1 ratio. It has been reported that large-diameter myelinated axons have chronaxie times ranging from 50 to 100 μs and 30 to 200 μs, and neuronal cell bodies and dendrites have chronaxie times ranging from 1 to 10 ...
