Effect of temperature, density, and strength of electric current on the spectra of gases
(University of Missouri--Columbia, 1901)
Light may be defined as that vibration of the ether which, acting on the organ of sight, produces in us the sensation of vision. But when, on reflection, we realize that the sense of sight is the most useful of all man's ...
Electrolytic rectifiers
(University of Missouri--Columbia, 1912)
More than a half-century ago, Wheatstone, in experimenting with the electro-chemical behavior of certain elements, laid the foundation for the modern chemical rectifier. In the year 1855, he found that aluminum as anode ...
The [alpha]-rays and the [alpha]-particle : a study of ionization and allied phenomena produced by [alpha]-rays
(University of Missouri--Columbia, 1910)
As a result of experiments by M. Henri Beoquerel in 1896 we now know a certain class of chemical elements as Radio-active. A radio-active body gives off radiations that have the following effects: 1) they will affect a ...
Paramagnetic and diamagnetic substances and the effect of temperature on them
(University of Missouri--Columbia, 1901)
In the latter part of the eighteenth century only a few substances, such as iron, nickle, and cobalt were thought to possess magnetic properties. Little by little, research work has gone on until now, it is believed that ...
The acceleration of gravity : an absolute determination with a Kater's pendulum for Columbia, Missouri
(University of Missouri--Columbia, 1913)
Galileo Galilei (1564-1642) was the first to question the assertion of Aristotle that bodies fall with velocities proportional to their weights. He dramatically refuted this Aristotelian doctrine by dropping from the Tower ...
The absolute measurement of electrical capacities
(University of Missouri--Columbia, 1913)
Of the various methods in use at the present time for the absolute measurement of electrical capacities in electromagnetic units, none give the satisfaction desired. Only two of these methods are in common use and they ...
Cathode disintegration
(University of Missouri--Columbia, 1911)
It has been pointed out that the cathode disintegration depends upon the gas present as well as upon the metal of which the cathode is composed. Hence it was thought interesting to investigate whether the gas in which the ...
The atomic weight of lead from samarskite
(University of Missouri--Columbia, 1918)
Text from page 1: In the disintegration of the radioactive elements, since each a-transformation involves the loss of an atom of helium and nothing else which in weighable, the atomic weight of the product should be just ...
