During 1860s, James Maxwell, a Scottish physicist forecasted presence of radio waves. And in year 1886, Heinrich Hertz showcased projection of swift variation of the electric current into space in form of radio waves. Twenty years after invention of telephone, music was set down on telephone line and Guglielmo Marconi was responsible for the radio signals. Fascinated by Hertz’s discovery of the radio waves, he realized that it could be used for receiving and sending the telegraph messages, referring to it as wireless telegraphs.
History of electric light, which adds to our daily convenience, bears testimony of many scientists, physicist’s efforts. Some people who took a step forward in the field were James Lindsay, Frederick Moleyns, Heinrich Göbel, Humphrey Davy and Warren Rue and Thomas Edison. Humphrey Davy offered a miner lamp by working out on formulation for electric arc. In year 1802, he demonstrated workings of electric arc with the help of 2 wires- one attached to battery and other to the thin charcoal piece. In 1820, Warner Rue produced light bulb by using platinum coil in empty tube and passing electric current through it.
In October 1969, Willard Boyle and George Smith discovered Charged Coupled Device (CCD) which is known to be heart of every digital camera. By 1970, Boyle and Smith built CCD into earliest solid state video camera. And soon after, in year 1975, both of them showcased first CCD camera with sharp image quality for the broadcast TV.Not until 1981, Sony Corporation launched prototype digicam, Mavica electronic still camera. This camera recorded pictures as the magnetic impulses on small 2 inch video floppy. Capturing of these images was done through 2 CCD chips.
The history of ball pen can be traced back to 1880s, when the first patent on a ball pen was issued to John Loud.This leather tanner attempted to make a writing object with which he could write on the leather he tanned.The second innings for the ball pen began with the first and very famous stylized fountain pen. Invented by Cross, this fountain pen is identified as daddy to the ball pens. This invention triggered more of brainstorming that lasted till ball pen was born. Ever wondered, such a small item has given the world so much.
We all are a part of the tech savvy century where our lives are comforted by various machines. Whether it is cell phones, laptops, motion detectors, digital watches, ATMs or videogames, technology is all around us. The diverse inventions have certainly made our lives simpler, easier and entertaining. But do you know what is common in all these machines? The common thing is the electronic heart of these machines- integrated circuit. As vital as a heart is to human body, the integrated circuit is a lifeline of these machines. Let’s have a rendezvous with people who offered this electronic heart to the world. Jack Kilby is one of the heroes from the success story of microchip. Among very few who really thought of giving something to the society that could truly transform the way it works, Kilby was one of them. He had an important role in offering a breakthrough to the technological world.
