to the same number as the row and column sum.Bachet was famed as a poet, translator and early mathematician of the French Academy. He is best, known for his translation of 1621 of Diophantus' Arithmetica. This is the book which Fermat was reading when he inscribed the margin with his famous Last Theorem. Bachet, however, is also famed as a collector of mathematical puzzle which he published ...
했다. 1860년대에 프랑스와 이탈리아에는 코카인을 넣은 포도주가 인기를 끌었다. 또 'French Wine Cola'라는 상품이 있었는데, 초창기에는 인기가 없던 이 음료에서 술 성분은 빼고 코카인과 카페인으로 새로 만든 음료를 만들어 판 것이 바로 코카콜라(Coca-Cola)다. 이 음료는 1920년대 까지 팔리다가 ...

It acts on the circulatory, gastrointestinal and nervous system, and when given to humans causes sedation.The French mouse behaves normally until it is stressed by exposure to a laud noise and then put in a big space.

우린 스스로를 절멸시켜 쓰레기로 만들어버린 후일까?The word "garbage" may derive from the old French "garbe" for sheaf. Some people think it's from "garbelage" - removal of refuse. A 1942 dictionary dismisses garbage as "animal or household refuse," or "low or vile things collectively." The Oxford English Dictionary adds "worthless or foul literary matter" and a brand-new ...
to the Moon.In fact, this was the way in which the hero of "A Voyage to The Moon" began his trip through space. Some French soldiers strapped rockets to his vessel as a joke and set them off. When the rocket impulse died, our hero rubbed himself all over with bone marrow and that carried him the rest of the way.

It now has a population of about a million, mostly of Indian and African descent. With all due respect to the people of Mauritius, however, ...
show how atoms(if they existed) would bombard tiny particles in solution and cause them to move randomly. In 1913, a French scientist, Jean B. Perrin, used the equation to calculate how large atoms would have to produce the motion as observed. It turned out they were about 1/250,000,000-inch across. The fact that small particles in solution do move exactly as though atoms were hitting them ...
rays in 1985 and won worldwide fame and a Nobel Prize. Other physicists longed to make similar discoveries.In 1903, a French scientist, Rene P.Blondlot, was convinced he had. He reported certain mysterious "N-ray" (N for Nancy, his native city) that were very difficult to detect, but which he managed to see. Others excitedly repeated his experiments and confirmed them, especially in France. ...
but these represented only a small improvement. Still shorter waves could not be focused properly.But then, in 1923, a French scientist, Louis de Broglie, pointed out that subatomic particles ought to exist in wave form, too. In 1925, an American scientist, Clinton J. Davisson, was able to detect such waves produced by electrons. These electron-waves were much shorter than ordinary light ...
50여년간의 숙제를 푼 중요한 사건이었다. 1976년에는 미국 육군본부에서 프렌치(French)중령이라는 미생물학자가 우리의 연구결과를 직접 확인하러 왔다. 우리 연구소에서 1주일간 머문 후 그가 서울을 떠나면서 한 말은 지금도 잊을 수 없다."많은 미국학자들은 당신의 발견을 의심하고 있습니다. 특히 ...
