How to become famous to the chemist? Very simply! In honour him an open by him reaction, new substance or even reagent, can be adopted! But if it not enough, then for such scientist I am and another method to leave memory about itself : to work out tableware, device or other device that will be named his name.Through years the name of this tableware will dwindle simply to the last name of scientist - in a laboratory we talk the "refrigerator of Liebig" rarely, "attachment of Вюрца". Is it more often possible to hear something type: "And who вюрца unwashed in a shell gave" up? or: "Again at либиха someone broke" off a paw.The devices created by scientists in a help to the researches became the heroes of this book. Do many know, who such Petry, the cup of the name of that is used by both chemists and microbiologists, and who will say навскидку, who did invent such device, how a pipette is? Who to mention a kind word, when we bury to itself in eyes of drop?
