in 1903, unbreakable or bulletproof glass was invented by the French chemist Edouard Benedictus.


As is the way with most great inventions, his discovery
was made quite by accident. He was on a ladder
reaching for something on a high shelf when he knocked
a glass flask to the ground.

 Did you know that "Semen contains small amounts of more than thirty elements, including fructose, ascorbic acid, cholesterol, creatine, citric acid, lactic acid, nitrogen, vitamin B12, and various salts and enzymes.   Semen contains small amounts of more than thirty elements, including fructose, ascorbic acid, cholesterol, creatine, citric acid, lactic acid, nitrogen, vitamin B12, and various salts and enzymes. Let's go back to the inside of the head of the sperm. All normal cells have 46 chromosomes but sperm have half that number or, 23. If and when the sperm joins ups with the female's, egg (ovum) which also has 23 chromosomes, together they add up to 46 chromosomes. The middle section controls the sperms activities. The sperm or (spermatozoa -- which are the little swimming critters) make up only about 5% of what a man ejaculates each time he ejaculates. This represents about 100 to 400 million of them! Therefore, they are very, very tiny, in fact a singl...

 Did you know the Eiffel Tower was originally intended for Barcelona, Spain, but the project was rejected.   on May 6, 1889, the Eiffel Tower was opened to the public.  The  Eiffel Tower was originally supposed to be in Barcelona. But thinking the thing would end up looking like an eyesore, the city rejected Gustave Eiffel's plans, and he was forced to repitch the project elsewhere. Luckily, Eiffel found a home for his idea in Paris, where the Tower could serve as the main archway for the 1889 International Exposition. Amazingly, the Tower didn't exactly go over well with the Parisians, either. The enormous iron structure was immediately belittled by critics, and one especially harsh reviewer referred to the thing as a "metal asparagus." Truth be told, the Eiffel Tower wasn't supposed to stay up for very long. In fact, it was offered for sale as scrap and was spared only because it proved useful to the French army. (They found that its 984-foo...

(1953) NNAMDI AZIKIWE, “SPEECH ON SECESSION” As one who was born in the North, I have a deep spiritual attachment to that part of the country, but it would be a capital political blunder if the North should break away from the South. The latter is in a better position to make rapid constitutional advance, so that if the North should become truncated from the South, it would benefit both Southerners and Northerners who are domiciled in the South more than their kith and kin who are domiciled in the North.  There are seven reasons for my holding to this view. Secession by the North may lead to internal political convulsion there when it is realized that militant nationalists and their organizations, like the NLPU, the Askianist Movement, and the Middle Zone League, have aspirations for self-government in 1956 identical with those of their Southern compatriots. It may lead to justifiable demands for the right of self-determination by non-Muslims, who form the majority of the ...
