Eiffel Tower

A frequently cited example of protection from atmospheric corrosion is the Eiffel Tower. The narrow and, for that age, thin sections required a good priming of red lead for protection against corrosion. The top coat was linseed oil with white lead, and later coatings of ochre, iron oxide, and micaceous iron oxide were added. Since its constmction the coating has been renewed several times [29]. Modern atmospheric corrosion protection uses quick-drying nitrocellulose, synthetic resins, and reaction resins (two-component mixes). The chemist Leo Baekeland discovered the synthetic material named after him, Bakelite, in 1907. Three years later the first synthetic resin (phenol formaldehyde) proved itself in a protective paint. A new materials era had dawned. 

The long thin loaves of French bread are regarded in the rest of the world as an icon of France, alongside the Eiffel Tower. Their origin is said to be that one of the Austrian queens of France demanded the sort of loaf that she was accustomed to in Vienna. Possible candidates for the queen would be Anne of Austria, wife of Louis XIII, or Marie Antoinette, wife of Louis XVI. As central European wheat is hard, resembling North American wheat, this is a formidable problem with only French soft wheat available. A modern bakery technologist would find this difficult.

Symmetry is a phenomenon of the natural world, as well as the world of human invention (Figure 4-1), In nature, many types of flowers and plants, snowflakes, insects, certain fruits and vegetables, and a wide variety of microscopic plants and animals exhibit characteristic symmetry. Many engineering achievements have a degree of symmetry that contributes to their esthetic appeal. Examples include cloverleaf intersections, the pyramids of ancient Egypt, and the Eiffel Tower. 

The famous Eiffel Tower, built for the 1889 Paris Exposition, has inspired many crazy stunts, for example, in 1891 Silvain Dornon climbed the 363 steps on stilts.

Remarkably, subpicosecond injection rates were measured with Ru sensitizers anchored to a surface about 24 A from the semiconductor surface if the idealized Eiffel Tower-like orientation shown was achieved.118-120 Of course delocalization of the excited state onto the phenyl ethyne substituents of the bpy ligands would decrease the injection distance. Indeed, this bridge may act as a conduit for excited-state electron transfer to Ti02-12°...

France and studied history at the Sorbonne. During World War I, he was stationed in the Eiffel Tower as a radio engineer. Intrigued by his exposure to radio communications, he returned to school after the war, earned a Ph.D. in physics, and became a professor of theoretical physics at the Faculte des Sciences at the Sorbonne. He received the Nobel Prize in physics in 1929, five years after obtaining his degree, for his work that showed electrons to have properties of both particles and waves. In 1945, he became an adviser to the French Atomic Energy Commissariat. 

Our focus in this review is on the luminescence behavior of solid state lanthanide and transition metal systems over a pressure range extending up to 300 kbar. Since this magnitude of pressure is well beyond everyday experience, it is beneficial to consider how these pressures compare to those encountered in the physical world. Table 1 presents selected examples from a more comprehensive compilation presented by Jayaraman [68]. The pressures in Table 1 range from 10 bar in outer space to 10 bar at the center of the sun. The unit of pressure of relevance to this review is the kbar. From Table 1, we see that 1 kbar corresponds approximately to the pressure at the deepest point in the ocean. A pressure of 50 kbar would result if one were to invert the Eiffel tower and place it on...

Eiffel tower in Paris (Figure 1.1) is a good example of a new structure based on the principle of modern foundation engineering. Alexander Gustave Eilfel built the tower in 1889. Eiffel realized that a good foundation is vital for the tower in order not to suffer the same fate as the Leaning...
