Absolute hot. Absolute hot is a concept of temperature that postulates the existence of a highest attainable temperature of matter. Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has the value 1.416785(71)×1032 kelvin.[3] This value is assumed to be the highest temperature because conventional quantum physics relies on Planck's law which implies a lower limit for the wavelength of electromagnetic radiation.
The models of the origin of the universe based on the Big Bang theory assume that the universe has passed through this temperature about 10−42 seconds after the Big Bang as a result of enormous entropy expansion.[3] Above ~1032K, particle energies become so large that there is no existing scientific theory for the behavior of matter at these energies. Gravitational forces between them would become as strong as other fundamental forces, requiring a hypothetical theory of everything for description.[4] See also[edit]
Absolute zero. Absolute zero is the lower limit of the thermodynamic temperature scale, a ficticious state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0. The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15° on the Celsius scale (International System of Units),[1][2] which equates to −459.67° on the Fahrenheit scale (English/United States customary units).[3] The corresponding Kelvin and Rankine temperature scales set their zero points at absolute zero by definition. The laws of thermodynamics dictate that absolute zero cannot be reached using only thermodynamic means,[clarification needed] as the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically.
A system at absolute zero still possesses quantum mechanical zero-point energy, the energy of its ground state. The kinetic energy of the ground state cannot be removed. Biology. Launching Anvils 200 Feet Into the Air. (YouTube Link) Gay Wilkinson likes launching iron anvils high into the air. He's not entirely sure why and has a lot to say about how men and women respond differently to his hobby.
Anyway, he places one anvil on top of another and fills the reservoir in between with gunpowder. Next Wilkinson herds the crowd to a spot about 50 feet from the loaded anvils and delivers a well-rehearsed introduction. "It'll be loud, but ya won't hardly remember that 'cause there'll be so much else goin' on," he says. "There'll be a slight second of fear after that anvil goes shootin' up and starts comin' back down.

Lateral Science - Galvanic Reanimation of the Dead - Galvanic Reanimation of the Dead The exploits of nineteenth century scientists with electrical batteries and corpses. In 1803 Giovanni Aldini (Galvani`s nephew) performed experiments, in public, upon the severed heads of "malefactors" despatched in Bologna and at Newgate, London. A few accounts of these horrific demonstrations - A very ample series of experiments were made by Professor Aldini which show the eminent and superior power of galvanism beyond any other stimulant in nature. In the months of January and February last, he had the courage to apply it at Bologna to the bodies of various criminals who had suffered death at that place, and by means of the pile he excited the remaining vital forces in a most astonishing manner. George Forster was hung at 8am on 18th January 1803 at Newgate Prison, for the drowning of his wife and youngest child in the Paddington Canal.
After hanging for an hour in sub-zero temperatures, Aldini procured the body and began his galvanic experiments.
