The Life of Thomas Alva Edison

As we know Edison was an American inventor. Edison was born in 1847 in Milan, Ohio. He developed many electrical devices such as electric power generator, mass communication, Sound recording device, motion picture camera and long-lasting practical electric light bulb.

Edison was married twice, his first wife died young. Both wives complained that he spent most of his time in the lab and had little time for his family.

While he was working for Western Union, America’s leading electrical enterprises at the time, Edison became famous for his ability to cure ‘bugs’. He frequently worked all night at the company’s headquarters and was described by the company’s operating chief as a ‘genius’ and a ‘friend for work’ who had ‘unfailing self-confidence.’

Edison worked up to 18 hours a day. His ability to live off four hours of sleep a day – and the occasional catnap – was widely known. Edison used to say, Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time vitality and also opportunities.”

He strongly believed that “accomplishing something provides the only real satisfaction in life”.




Do you know what is AFM?

AFM stands for atomic force microscope. Gerd Binnig, Calvin Quate and Christoph Gerber invented the first atomic force microscope in 1986. It is a type of high-resolution scanning probe microscope that has a resolution that you can measure in a fraction of a nanometer.

The AFM ‘feels’ the atoms rather than ‘sees’ them. The AFM is one of the foremost tools for imaging, measuring, and manipulating matter at the Nano scales. It is very versatile, and this versatility has led to an explosion in the number of scientists using the instrument.

Mr. Nano

Eric Drexler is often described as ” the founding father of nanotechnology ”. He was the first to publish a technical paper, and book on molecular nanotechnology. For this reason, he is also called Mr. Nano.
