Towards the end of 1800s, images were transferred through fax machine for the first time. Soon after telephone came into being, electrically powered transmission of moving TV images, known as telephonoscope, was started. Science fiction writers were of the view that light would pass via wires like sound some day. And many people have worked hard to offer this exquisite instrument of entertainment. Revolutionary works of Michael Faraday and Joseph Henry in 1831, launch of pantelegraph by Abbe Caselli and works by inventors and scientists Sheldon Bidwell, George Carey, Edison, Bell and Eugen Goldstein, all made way to Nipkow invention.
World’s first ever satellite was launched on October 4, 1957 by Soviet Union. Weighing 183 pounds, it took around 98 minutes to orbit Earth. While launch of the satellite was just a single event, it marked the beginning of space age and steered new military, political, scientific and technological developments. White House declared plans of launching earth orbiting satellite and requested proposals from different governmental research agencies for undertaking development in July 1955. Vanguard proposal by Naval Research lab was picked for representing U.S during International Geophysical yr.
Since the time human beings saw birds soaring through sky, they wished to fly. Ancient Romans and Greeks portrayed many mythological animals and gods with wings. Around 100 BC, Hero of Alexandria, a Greek Inventor, introduced a device known as aeolipile. The device used mechanical interaction of water and heat to work. Steam generated through the two elements was its driving force. Towards the end of 17th century, scientific fundamentals were laid for the contemporary rocketry. Isaac Newton had worked on his perception of physical motion in 3 scientific laws. His laws give a peep into how the rockets functions and how are they able to work in vacuum of the outer space. His laws were soon seen to impact designing of the rockets.
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.
Rat race of collecting arms for the national détente is not new. Weapons have been used from time immemorial. Whether for purpose of self defense or offence, guns have a fascinating history. Robert Bacon is also known to be the inventor of gunpowder according to a theory. He is supposedly said to have found its recipe among the chemical formulas. Regardless of who gunpowder’s inventor was, mythical monk from Germany is believed to have given idea of propelling projectile with the gunpowder in the 1300s. And Arabs are known to be inventors of earliest cannon named madfaa. This cannon was a wooden bowl with gunpowder in it.
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.
