Several weeks ago, I went to a lecture at Jewis Hospital with Eriko, Khuloud and Alex. The topic was Alzheimer disease. I already knew a little beat about this diasease, but the lecture helped me to improve a lot my knowledge, even sometimes wasn't easy to follow.
The speaker presented very well, in a manner that even we as ageneral public were able to understand the main ideas. He used a lot of examples and even few jokes to make it more interesting.
I enjoyed this project, it is exciting to go out to find information and then go back and let the others know about it.

The term "skyscraper" was used in 1880; after the first tall buildings were build in the
Before there were towers made of heavy stone. Towers had thick walls and the rooms were dark and overcrowded. Windows weren’t very common, it could disadvantage the structure.
With the discovery of the steel begin the new era of modern skyscrapers. The
New structural designs made skyscrapers even lighter and stronger.
As skyscrapers get taller and taller, engineers were faced with a new problem: the wind. Today's tallest skyscrapers, which are almost 1,500 feet tall, must be 50 times stronger against wind than the typical 200-foot buildings of the 1940s.

Skyscrapers represent the big issue for the population explosion in our days. In my opinion skyscrapers is a good think because it permits to locate a big number of people in one place into the profit of green spaces that can be saved.
