Nano technology deals at the micro level and concerns itself with the atom level functions of materials. Simply put – Nanotechnology is the study of small things. Things at this scale can behave very differently than what we expect. Think about carbon, arrange it one way you get diamonds, arrange it another way you get graphite, arrange it randomly you get soot. Scientists are experimenting with nanotechnology that can arrange and organize themselves. In the nano scale you start with atoms and build your way up. It’s currently in its infancy as a study, but will increasingly become more useful and advantageous in innovating the way we do things.
A nice little primer on how your inkjet printer works. Some pretty interesting information in here, such as an ounce of ink is worth 30 times the cost of a drop of a good champagne.
C Hewing Gum dates back to the ancient Greeks, who chewed resin from trees. Modern gum patented in the US by a dentist in 1869. Bubble Gum was later invtented in 1928. Earlier gums were created from tree resin, but today’s gum are made synthetically from plastics and rubbers which are edible but presumably you wouldn’t want to swallow it since the body has a hard time processing and breaking it down. Contrary to popular belief, swallowing gum will not stay in your body for 7 years.
You likely use or encounter them everyday (at least I would hope so), but for something so inconspicuous we really don’t give much thought to how exactly light bulbs work. Well if you’ve ever wondered, here’s a rather nice explanation on what exactly occurs when you flip a light switch.
