What is the importance of Eiffel Tower?
Eiffel realised that the height of the tower could be utilised as an observatory. In 1889, he started using the peak of the tower as an observation station for the measurement of the wind speed. Other scientists also conducted experiments at the tower. Subsequent to experimentation in the sphere of meteorology, Eiffel began to observe the relationship and the effects of wind and air resistance. This science was later on classified as aerodynamics, which has now become an essential part of military and commercial aviation as well as rocket technology. In 1910, Gustave Eiffel achieved extraordinary results in measuring the wind resistance of a flat plate by using the Eiffel Tower as a test platform. To overcome the lack of available measuring instruments, Eiffel proceeded on to a quest for more sophisticated knowledge of aviation which ultimately led to wind tunnel experiments. In order to safeguard the tower from wear and tear, huge maintenance work is essential. This programme includes applying 50 to 60 tonnes of three graded tones of paint once every seven years to protect against rust. At each occasion when it is required to paint, the shade of paint is changed. Currently, the tower is painted with a shade of brownish-grey - the darkest layer is painted on the top which gets lighter towards the bottom. The Eiffel Tower has played a role in communication since the first decade of the preceding century. French radio, though regular transmission was started in 1922, maintained an aerial on the tower, and began transmissions from the tower in 1918. For FM (Frequency Modulation) and TV transmission, the Eiffel Tower has been an important platform since 1957. Lee de Forest, a French engineer and scientist who wanted to pioneer wireless telephony, broadcasted a phonograph record show from the Eiffel Tower on January 12, 1908, for an audience of less than 50 people; the show was heard over 500 miles from the tower. This occasion is marked as the first ever experience of long-distance radio message transmission. Eiffel Tower also has the distinction of being an active part of the first transatlantic and transcontinental radio telephone call. On October 21, 1915, radiotelephone communication was made between Naval radio station NAA at Arlington, Virginia and the Eiffel Tower.
How did immigrants get to Australia in the 1960's?
Air planes were starting to take over from the traditional migrant ships.
From what Alcinous says about Phaeacia's ships is there any chance that they will fail to get Odysseus home?
No, not at all. They are a sea-faring folk, and sail the seas by the grace of Poseidon in ships that glide along like thought, or as a bird in the air.
What taxied the plane to the runway?
Air Traffic Control - usually on the ground frequency for that airport. Switching to tower, when ready for takeoff.
Radar and sonar originally develped for?
Detecting and ranging (measuring the distance of) enemy craft in air (planes) and water (ships and subs).
Which french landmark rises more than 300m into the air?
Eiffel Tower
How has pollution affected the Eiffel Tower?
Eiffel Tower is one of the most celebrated landmarks in the world and represents Paris .The Eiffel Tower now generates its own power with new wind turbines. The turbines are expected to produce about 10,000 kilowatt hours (kWh) of electricity per year.
Is the Washington Monumet taller then the Eiffel or the Eiffel?
The actual monument is taller than the actual Capitol, but the Capitol is on top of Capitol Hill. Therefore, the US capital is higher in the air than the Washington Monument. No buildings in DC are allowed to be higher than the Capitol on top of Capitol Hill.
Who designed the Eiffel Tower?
It was Alexandre-Gustave Eiffel.
How is the Eiffel Tower weathering?
The Eiffel Tower, made of wrought iron, is weathering primarily through a process called corrosion. Corrosion occurs when the iron in the structure reacts with oxygen and moisture in the air, forming iron oxide (rust). This process weakens the iron structure over time, leading to maintenance efforts such as regular painting and rust removal to preserve the iconic landmark.
Why is Eiffel tower higher in Summer?
The Eiffel Tower is very slightly (i.e., mere centimeters) taller during the summer than during the winter. The reason for this is due to thermal expansion. During the summer, the structure is heated by the sun for more hours during the day, and the warm air of the summer makes it harder for the tower to stay as cool as it gets in the winter. Therefore, the molecules in the structure expand, causing the entire tower to grow by a few centimeters.

How do people depend on the environment in Paris?
People in Paris depend on the environment for clean air and water, access to green spaces for recreation and relaxation, and a sustainable ecosystem that supports biodiversity. The environment also plays a role in shaping the city's culture and identity, such as the presence of iconic landmarks like the Seine River and the Eiffel Tower.
When was Tower Air created?
Tower Air was created in 1982.
When did Tower Air end?
Tower Air ended in 2000.
How much does a Macbook Air Dock cost?
435
What does steak eat?
steak eats people named Zach, Orion, Max, Michael and Bob. It also eats oxygen or air. It also eats grilled bacon that has been in Belgium and Italy and up the Eiffel tower and back.
