It is not certain when people first started wearing
clothes however, anthropologists give estimates that range between 100,000 to 500,000 years ago. When settled neolithic cultures discovered the advantages of woven fibers over animal hides, the making of cloth, drawing on basketry techniques, emerged as one of humankind's fundamental technologies.
Did you know that the
bikini was named after the Bikini Atoll in the Marshall Islands, the site of atomic bomb testing?
vacuum tube is a sealed glass or metal-ceramic enclosure used in electronic circuitry to control the flow of electrons.
Vacuum tubes go back to 1875 when American, G.R. Carey invented the phototube. The vacuum tube was made obsolete by the tiny and cheap
transistor invented in 1947. Until then, vacuum tubes were found inside every
computer, and almost all other electronic devices.
Needed to clean the tubes. Not! Just joking folks. However, did you know that early vacuum cleaners were large, horse-drawn and petrol-driven units that were parked outside the building to be cleaned with long hoses fed through the windows.

The first lamp was invented around 70,000 BC. A hollow rock, shell or other natural found object was filled with moss or a similar material that was soaked with animal fat and ignited. Sir Humphrey Davy of England invented the first
electric carbon arc lamp in 1801. A carbon arc lamp works by hooking two carbon rods to a source of electricity. With the other ends of the rods spaced at the right distance, electrical current will flow through an "arc" of vaporizing carbon creating an intense white light.
Device Records Smells
Ok kids, now you will be able to send someone the smell of the ink hot off the press. According to a NewScientist.com news article by Paul Marks, Pambuk Somboon and a team of engineers at the Tokyo Institute of Technology in Japan are building an odour recorder. Paul Marks describes Somboon's system as using 15 chemical-sensing microchips (electronic noses) to pick up a broad range of aromas. These are then used to create a digital recipe from a set of 96 chemicals that can be chosen according to the purpose of each individual gadget. When you want to replay a smell, drops from the relevant vials are mixed, heated and vaporised.
