(1.) The guillotine is an instrument employed for the purpose of decapitation. It was officially introduced into France as the means of inflicting capital punishment in April, 1792. It was named after its reputed inventor, Dr. Joseph Ingace-Guillotin, who, contrary to popular belief, died a natural death, and not a victim of his own invention. The instrument consists of two upright posts held together at the top by a cross beam, the former being perpendicularly so grooved as to allow of the falling in a direct line a broad steel blade, whose edge is cut obliquely. The latter, sometimes weighted with lead, descends upon the neck of the criminal immediately after the cord which holds it up is released by the executioner.
(2.) A guillotine is a machine, similar in name and in general construction to the above, employed by bookbinders. It is used for cutting paper and trimming the edges of books after the sheets have been sewn together.

In Norse mythology, Nornagesta was fated by the three Norns: Urd, Verdandi, and Skuld. Urd and Verdandi gave him a rich, heroic life. Skuld said he would live no longer than a burning candle. Nornagesta kept the candle safe and hidden and lived to be 300 years old. King Olaf found the candle, burned it, and Nornagesta died.

The word "parachute" comes from "para", meaning "against" or "counter" in Ancient Greek, and "chute", the French word for "fall". Some modern parachutes are classified as semi-rigid wings, which are maneuverable and can make a controlled descent to break on impact with the ground.

"Thus, we have a cannon planted on a towwer at such a height that it would take four seconds for a ball to fall from it to the ground. Dropped from the cannon's mouth, in the first second a ball would reach A; in the next, B; in the third, C; and in the fourth D." —Quackenbos 1859

"See o'er this icy pathway pictured here, / Three sturdy travelers on foot appear; / One of them slips - he breaks his bones - / 'So much for hurrying,' thus he inward groans: / The man more wise and careful goes more slow, / Looks where he steps, and doth more surely go."—Barber, 1857

"When a water fall ranges between 10 and 70 feet, and the water supply is from 3 to 25 cubic feet per second, it is possible to construct a bucket wheel on which the water acts chiefly by its weight. If the variation of the head-water level does not exceed 2 feet, an overshot wheel may be used. The water is then projected over the summit of the wheel, and falls in a parabolic path into the buckets. With greater variation of head-water level, a pitch-back or high breast wheel is better. The water falls over the top of a sliding sluice into the wheel, on the same side as the head race channel. By adjusting the height of the sluice, the requisite supply is given to the wheel in all positions of the head-water level. The wheel consists of a cast-iron or wrought-iron axle C supporting the weight of the wheel. To this are attached two sets of arms A of wood or iron, which support circular segmental plates termed shrouds B. A cylindrical sole plate dd extends between the shrouds on the inner side. The buckets are formed by wood planks or curved wrought-iron plates extending from shroud to shroud, the back of the buckets being formed by the sole plate." — Encyclopedia Britannica, 1893
