Invention of dynamite
Alfred Nobel was a Swedish industrialist, engineer and inventor. He was into construction and that led him to perform an experiment to find out ways of blasting rocks. His research led him to nitroglycerine. He found out that mixing silica with nitroglycerine would make it easy to handle. This mixture is known today as dynamite.

How pure are Olympic gold medals?
The Olympic gold medals are mostly made of silver, not gold. Only six grams, or 0.19 ounce, of gold is required to coat the medal. The medal itself is made of 92.5 per cent or 550 grams of pure silver. The medals are usually circular with a diameter of a minimum of 60 mm and a thickness of a minimum of 3 mm. These specifications are as per the Olympic Charter. The last time a pure gold medal was awarded in the 1912 Olympics in Sweden.
