A New Technological approach

Actually in present times advanced technology has been creating disasters.  So Pessimists are coming up with the idea that scientific research should not be encouraged. It is not correct to say in that manner. Without science we would not have been reached that stage. There is still need to scientific research as people are becoming so lazy to do any work. We need servants to do our work.  But now a day’s people attitude is becoming narrow. They just wanted themselves to develop. The “most generous people” of this generation will be thinking up to their country. So as long as the people’s attitude doesn’t change it is not appreciable to go against pessimists. As long as the governing bodies can’t control the selfish narrow minded politicians and technocrats it is not appreciable to encourage the upcoming scientific research. Let us motivate our generations and keep alive our scientific progress.

Accidental inventions 1



                
All think that there will be a great hard work and brain work and will power behind inventions. It may be true in many cases. But there are some inventions which are accidental. Some of them are as follows:-



1.     Ice cream cones: - An ice cream stall at the 1904 world fair in St.Louis, USA, ran out of dishes. The neighboring stall sold wafer thin waffles and stall holder came up with an idea of rolling them into a cone and topping with ice cream.

2.     X-ray:- While setting up cathode ray generator in 1895, Wilhelm roentgen discovered fluorescent effect on chemical coated screen in the room. He had discovered invisible X-rays, which pass through cardboard, wood, paper, but not through bones.


3.     Synthetic dye:- In 1856, William Perkin was attempting to produce synthetic quinine to treat malaria but the experiment produced a purple mess. Perkin spotted the opportunity at once and set up a factory to produce the first synthetic dye.
