SOME INVENTIONS HAPPENED IN A VERY INTERESTING WAYS IN THE HISTORY OF SCIENCE.
THEORY OF DISPLACEMENT -
The Ancient Greek scientist was trying to find a way of determining whether a crown was made of pure gold.While pondering the problem ,Archimedes climbed into his bath and saw the water level rise.He realized that he could compare the volume of gold in the crown with a lump of pure gold of the same weight by submerging them in a fluid and comparing the rise in water level.He leap out of his bath and cried "Eureka ,Eureka."("I have found it")
"Archimedes' principle indicates that the upward buoyant force ,that is exerted on a body immersed in a fluid ,whether fully or partially submerge, is equal to the weight of the fluid ,that the body displaces.Archimedes principle is a law of physic 's fundamental to fluid mechanics. Archimedes ,the great Greek scientist formulated this principle."
X-RAY- While sitting up a cathode ray generator in 1895 Wilhelm Roentgen noticed a faint fluorescent effect on a chemical coated screen in the room.This way he had discovered invisible X ray ,which can pass through cardboard ,wood,and paper., but not through bones.
SYNTHETIC DYE- In 1856 , , William perkin was attempting to produce Synthetic quinine to treat malaria but the experiment produced nothing but a purple mess.Perkin spotted an opportunity at once and set up a factory to produce the first synthetic dye.
MICROWAVE - A chocolate bar in Percy spencer's pocket melted as he stood in the path of radiation from a radar generating machine in 1945.He put corn kernel in the path of the beams, and they, popped .Then ,he had discovered the principle behind the microwave oven.
ICE CREAM CONES- As it happened ,an ice cream stall at the 1904 world fair in st Louis , USA , run out of dishes. The neighboring stall sold wafer -thin waffles and the stall holder came up with the idea of rolling them into a cone and topping with ice cream.Thus ice cream cones or softy Ice cream invented.
POST - IT@ NOTES - In 1968 , Spencer Silver was trying to find a new strong adhesive and came up with a glue that didn't even hold pieces of paper together firmly.In 1974 his co-worker Arthur -Fry thought of a use for the non sticky adhesive and the post-it@note was born.
