Even in summer the double period is not prominent in the arctic climate of Karasjok or on the top of the Eiffel Tower.
The engineer under whose direction the tower was constructed was Alexandre Gustave Eiffel (born at Dijon on the 15th of December 1832), who had already had a wide experience in the construction of large metal bridges, and who designed the huge sluices for the Panama Canal, when it was under the French company.
Erected for the exposition of 1889, the Eiffel Tower, in the Champ de Mars, Paris, is by far the highest artificial structure in the world, and its height of 300 metres (984 ft.) surpasses that of the obelisk at Washington by 42 9 ft., and that of St Paul's cathedral by 580 ft.
In the distance was a dark swath of park leading up to the lit-up Eiffel Tower, which was larger than she'd imagined.
Here a tower was begun on the lines of the Eiffel Tower in Paris, and projected to exceed it in height, reaching 1200 ft., but only a short stage was completed.
The room was dark, the floor-to-ceiling windows displaying the incredible views of the Eiffel Tower, whose frame was outlined by lights against the dark Parisian sky She was about to step onto the balcony when a knock at the door drew her attention.
The town, which is quite modern, contains many churches and chapels of all denominations, a town hall, public libraries, the Victoria hospital, three piers, theatres, ball-rooms, and other places of public amusement, including a lofty tower, resembling the Eiffel Tower of Paris.
From the Bureau Central and the Eiffel Tower, and the reduction of e 2 at the latter station, are unquestionably significant facts; but the summer value for c 2 at Karasjok - a low level station - is nearly as small as that at the Eiffel Tower, and notably smaller than that at the Sonnblick (3100 metres).
Chauveau points to the reduction in the 12-hour term as compared to the 24-hour term on the Eiffel Tower, and infers the practical disappearance of the former at no great height.
So again, in the case of the Paris curves, the absolute value of the diurnal range in summer was much greater for the Eiffel Tower than for the Bureau Central, but the mean voltage was 2150 at the former station and only 134 at the latter.
