The first transistor was handmade at Bell Labs in 1947. It didn’t look quite like what we are used to today, but it worked! -Thanks, Bill Hammack!

If you haven't had your big breakthrough yet, try one of these simple strategies: 1. CRACK OPEN A CAN OF BEER
Several nights later, while suffering from insomnia, Fraze went down to his workshop. By the next morning, he'd developed a built-in, tear-off opener for cans. Over time, Fraze refined the idea, and by 1965, 75 percent of American brewers were using Fraze's ring-pull design for their beer. 2. SHAVE YOUR STUBBLE
As a traveling salesman, he understood that the key to financial success was to create something that people would have to buy over and over again. But his big idea didn't hit him until he started shaving one morning in 1895. At the time, Gillette was using a traditional safety razor, which had to be sharpened after almost every use. So, Gillette imagined a blade that could simply be thrown away when it became dull. By putting a sharp edge on a thin piece of sheet steel, he created the first disposable razor. It took him eight years to get the invention to market, but once it hit stores, Gillette quickly became a millionaire.
In 1913, he retired to California to grow fruit and pursue his utopian dream of founding a city called Metropolis, where everyone would live in perfect harmony. Let's just say the shaving venture went more smoothly. 3. TAKE A COLD SHOWER
One morning, Hoerni was taking a shower when he noticed the way the water flowed over his hands, and it gave him an idea. If the transistors could be coated in the right substance, then dust and moisture would just flow right over them. He then thought of silicon dioxide, the perfect material for the job. His solution eventually led to the integrated circuit, the silicon chip, and almost everything else to come out of Silicon Valley. (Photo: Fairchild Semiconductor) 4. WALK THE DOG
A few weeks later, he was walking his dog in the woods when he noticed that his pants were covered in burrs. When he got home, he examined one of the burrs under his microscope and noticed that it was covered with tiny hooks that stuck to the small loops of thread in his clothes. By replicating the idea using little hooks and loops made of nylon, de Mestral developed Velcro. He eventually sold the rights to the patent and made millions in royalties, never to deal with zippers again. (Photo: Francoise and Charles de Mestral) 5. DREAM A LITTLE DREAM
Then one night, he awoke from a nightmare about being captured by cannibals and stuffed into a stew-pot. The dream nagged at him until he realized that the cannibals had each carried a spear with a hole in the tip. This was the breakthrough that Howe needed. Traditional sewing needle were designed so that the hole carrying the thread went through the fabric last. For Howe's machine to work, he needed the hole to go through first. He patented his sewing machine in 1846, but other manufacturers, including Isaac Singer, stole his design. After a lengthy court battle, Howe was finally awarded royalties on all sewing machine sales until both he and his patent expired in 1867. |

Take a look at the image above and tell us what do you see. A field of mushrooms? A series of tubes a la Super Mario Bros.? Actually they’re a crop of silicon nanowires, grown by IBM researcher Frances Ross. The gray columns are the wires and the black blob are liquid droplets that catalyze the growth of the nanowires.
One day, these mushroom-shaped wires just may replace today’s transistors:
In Dr. Ross’s laboratory at I.B.M., researchers are concentrating on more near-term technology. They are exploring the idea of constructing FinFET switches in a radical new process that breaks away from photo etching. It is a kind of nanofarming. Dr. Ross sprinkles gold particles as small as 10 nanometers in diameter on a substrate and then suffuses them in a silicon gas at a temperature of about 1,100 degrees Fahrenheit. This causes the particles to become “supersaturated” with silicon from the gas, which will then precipitate into a solid, forming a wire that grows vertically.
I.B.M. is pressing aggressively to develop this technology, which could be available commercially by 2012, she said. At the same time she acknowledged that significant challenges remain in perfecting nanowire technology. The mushroom-shaped wires in her laboratory now look a little bit like bonsai trees. To offer the kind of switching performances chipmakers require, the researchers must learn to make them so that their surfaces are perfectly regular. Moreover, techniques must be developed to make them behave like semiconductors.
