The eclipsing binary TV cassiopeiae
(University of Missouri--Columbia, 1917)
"The present discussion is based on 51 plates taken by Dr.Baker and the writer with the 5-inch camera during the period from July 1914 to October 1915. These plates where exposed about 1.5 mm. outside of focus, and were ...
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 ...
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 ...
Study of the spectroscopic binary [alpha] Andromedae
(University of Missouri--Columbia, 1912)
Spectrum analysis may perhaps be said to date from the year 1666 when Sir Isaac Newton discovered that rays of light of different colors are of different refrangibility. Later he discovered that a beam of white light coming ...
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 ...
The variable RS Cassicpeiae (108.1904)
(University of Missouri--Columbia, 1907)
The variability of this star was discovered by Madame Ceraski from plates made by Blakjo at Moscow, and was announced in A. N. No. 3953. The photographs indicated a variation from the ninth to the eleventh magnitude ...
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 ...
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 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 ...
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 [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 ...
Antalgol variable ST Ophiuchi (52.1907)
(University of Missouri--Columbia, 1911)
The variability of ST Ophiuchi was discovered at Harvard from an examination of31 photographs taken during the interval 1893-1904. Professor Pickering announced that the light variation was short duration, evidently about ...
