A fine aerial

“The installation of a wireless plant by the Department of Electrical Engineering necessitated the erection of steel towers on Maxcy and University Halls to carry the aerial.”

– Edwin A. Burlingame, Report of the Superintendent of Grounds and Buildings, Oct. 1916.

In 1916 Brown University announced that it would soon offer a course teaching students about a new technology: practical and experimental wireless telegraphy. It was more common during this era to transmit messages by radio waves using Morse code. Voice communication and broadcast radio did not become common until the 1920s. Continue reading A fine aerial

“The Magic Voice of Science”

“This is truly scientific magic. Just think of it! You want to know the true time to the fraction of a second, and all you have to do in order to get it is to open your electric ear to these sounds, which seem to drop out of the sky, as if Old Time himself were speaking to you!”

– Garrett P. Serviss, Wireless Time Signals from the Eiffel Tower. Washington Post, September 7, 1913.

During 1913 the Washington Naval Observatory and the Observatoire de Paris attempted to exchange wireless time signals. The experiment was used to calculate the difference in longitude between the two locations more accurately than was possible with other techniques. They were also trying to measure the velocity of radio waves through space. The goal was to improve communication with ships at sea which used the time signals to calibrate the chronometers used for celestial navigation. For most of the year atmospheric conditions prevented the reception of the signals sent across the ocean. The conditions improved in November and the two observatories were then in regular contact by radio. Prof. Winslow Upton of Ladd Observatory was listening in on the transmissions.
