Explanation :On November 7, 1867, the woman the world would know as Marie Curie was born as Maria Sklodowska in what is now modern-day Poland.
Pierre(Marie Curie husband) and Marie Curie set about working to search for the unknown element. They ground up samples of pitchblende, dissolved them in acid, and began to separate the different elements present, using the standard analytical chemistry techniques of the time. Eventually, they extracted a black powder 330 times more radioactive than uranium, which they called polonium. Polonium was a new chemical element, atomic number 84. When the Curies investigated further, they found that the liquid left behind after they had extracted polonium was still extremely radioactive. They realised that pitchblende contained another new element, far more radioactive than polonium, but present in even smaller quantities. In 1898, the Curies published strong evidence supporting the existence of the new element – which they called radium but they still had no sample of it. Pitchblende is an expensive mineral, because it contains valuable uranium, and Marie needed a lot of it.In 1902 Marie eventually isolated radium (as radium chloride), determining its atomic weight as 225.93. The journey to the discovery had been long and arduous.

Explanation :Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and water makes it useful for food packaging.As well as food packaging, cellophane is used in transparent pressure-sensitive tape, tubing and many other similar applications.
Cellophane was invented by Swiss chemist Jacques E. Brandenberger. It took ten years for Brandenberger to perfect his film. His chief improvement over earlier work with such films was adding glycerin to soften the material. By 1912 he had constructed a machine to manufacture the film, which he had named Cellophane, from the words cellulose and diaphane (“transparent”).

They managed to attach small petroleum based combustion engine to the wooden bicycle frame. This motorcycle called “Daimler Reitwagen” is today regarded as the first true motorcycle and it was a starting point for all future motorcycle based innovations and improvements.
During the one of the first test runs seat of the motorcycle caught fire from the heat emanated from the nearby engine. Daimler and Maybach patented during August 1885, and the final version of “Reitwagen” was presented to the public in 1886.
Original models of the “Daimler Reitwagen” were sadly lost in 1903 factory fire at Cannstatt, Germany. Several replicas exist in museum collections in Germany, USA, Australia and Japan.
