MIKE LASSITER (Refinery Supervisor, Barrick Gold Corporation): There's about a million and a half dollars there. DAVID POGUE: Oh, man! Watch out with the hammer. LAWRENCE L. DAVID POGUE: We live in a world of incredible material variety. Yet everything we know, the stars, the planets and life, itself, comes from about 90 basic building blocks,… You have a periodic table table. …all right here, on this remarkable chart: the periodic table of the elements. It's a story that begins with the Big Bang and eventually leads to us. Manganese! And we're made, almost entirely, of just a handful of ingredients, including one that burns with secret fire inside us all. Join me as I explore the basic building blocks of the universe… Oh! LINDSAY BAKER (Gatorade Sports Science Institute): …as hard as you can. …poisonous gases,… Isn't chlorine deadly?

Famous Scientists - Dmitri Ivanovich MendeleevDmitri Ivanovich Mendeleev Imagine if there was an element no one had ever seen before, but one day you announce that you know all its properties. People will call you crazy, won't they? But that's what Dmitri Mendeleev did! Mendeleev creates the Periodic Table The story goes like this. Mendeleev was studying the differences between the elements known then. a. their atomic number was nearly the same (like iron, cobalt, nickel and copper) b. their atomic number changed by an almost regular proportion (like chlorine, bromine and iodine) You could actually arrange them in a neat table. Here's what Mendeleev's table looked like: Today of course, it looks a bit different. But the best is yet to come. Mendeleev predicts new elements! He actually predicted that these gaps would be filled by elements yet to be discovered. ...and gets proved right! No one believed Mendeleev until a French chemist called Emile Lecoq came along. Mendeleev's Life Mendeleev's story is a very inspiring one. He died in 1907.
Amazing Rust.com - Hot IceHot Ice The picture to the left depicts pillars of Sodium Acetate Trihydrate which were created using Hot Ice solution. Supersaturated solutions of Sodium Acetate are used in certain types of hand-warmers. When a metallic button is pressed inside a plastic pouch, the supersaturated solution begins to crystallize, in the process releasing heat. Sodium Acetate is one of the products of the reaction between baking soda (Sodium Bicarbonate, NaHCO3) and vinegar (Acetic acid, HC2H3O2). The video below shows the Hot Ice phenomenon in action. Making Hot Ice In order to make Hot Ice, one must first create a supersaturated solution of Sodium Acetate. At a given temperature, only a certain amount of Sodium Acetate will dissolve in a certain volume of water. How will we create a supersaturated solution if we are only allowed to dissolve a certain amount of Sodium Acetate? Once the Sodium Acetate solution has become supersaturated the Hot Ice is ready to use. Videos What is happening?

Dmitri MendeleevDmitri Mendeleev revolutionized our understanding of the properties of atoms and created a table that probably embellishes every chemistry classroom in the world. Early Life and Contributions: Dmitri Mendeleev was born at Tobolsk, Siberia in 1834. He studied science at St. Petersburg and graduated in 1856. His greatest accomplishment, however, was the stating of the Periodic Law and the development of the Periodic Table. Legacy: Mendeleev was one of the first modern-day scientists in that he did not depend completely on his own work but rather was in correspondence with scientists around the world in order to receive data that they had collected. Besides his work on general chemical concepts as discussed earlier, Mendeleev spent much of his time working to improve technological advances of Russia. This work had been commissioned by the Russian Navy, which however did not adopt its use. Later Life:
