Much of the luxuries which have become necessities of modern life have been provided to us by the Russian scientists. Be it the yoghurt that owes its root in Bulgaria or television that was the result of engineering of Vladimir Zworykin, Russians have been responsible for much of our daily existence. Imagine life without modern day transportation vehicles, car, bus or helicopter? Vehicles today would have been mere objects of display if not for the petrol and the tyres. Cracking is a process that allows petrol to be produced in enormous quantities. Almost 70% of crude oil can be turned into petrol through the process of cracking, which was invented by Russian engineer Vladimir Shukhov. Synthetic rubber which is used to make tyres for vehicles and aircrafts was first developed by Russian chemist Sergei Lebedev. Helicopter was the brainchild of Russian inventor Ivor Sikorsky who is also credited with inventing the first hydroplane of the world and the first multiple-engine aircraft. Other scientific inventions that owe their root in the Russian soil include solar cell, videotape recorder, transformer and grain harvester.
