Question two? Which nineteenth century inventor holds one thousand, ninety three US patents, including those for the phonograph, motion picture camera, and practical electric light bulb. Question three? What revolutionary communication technology was patented on March seventh, eighteen seventy six by Alexander Graham Bell, who famously first used it to say, mister Watson, come here. Question four?

Question five? Which computer scientist is credited with inventing the World Wide Web in nineteen eighty nine while working at Cerne, later making it freely

1:33 available without patent or royalties. Will be right back with these innovative answers after this break, Welcome back trivia fans. Let's reveal today's answers. Question one, what office supply was invented by accident in nineteen sixty eight? Answer post it notes doctor Spencer Silver, a scientist at three M, was a attempting to develop a super strong adhesive, but instead created a weak, pressure sensitive adhesive that could be repositioned multiple times without leaving residue. Initially, the company struggled to find a use for this failure. Years later, another three M scientist, Art Frye, was frustrated by paper bookmarks falling out of his hymnal at church and realized Silver's adhesive could solve his problem. The iconic yellow color was chosen simply because the lab had scrapped yellow paper on hand during development. Question two, which inventor holds one thousand, ninety three US patents? Answer? Thomas Alva Edison, Often called America's greatest inventor, Edison developed numerous devices in fields such as electric power generation, mass communication, sound recording, and motion pictures.

2:52 While he's best known for the practical electric light bulb, his lesser known inventions include the concrete piano, an electric pen precursor to the tattoo gun, and even the first talking doll. Edison's laboratories in Menlo Park and West Orange, New Jersey, were among the first industrial research facilities, pioneering the model of organized systematic research and development. Question three. What technology was patented in eighteen seventy six by Alexander Graham Bell? Answer? The telephone. Bell was granted US patent one hundred seventy four thousand, four hundred and sixty five for a device that could transmit speech and other sounds telegraphically.

3:34 Just hours after receiving his patent, Bell made the first successful telephone call to his assistant, Thomas Watson, who was in another room. Interestingly, Bell faced over six hundred lawsuits challenging his patent, including a notable one from Elisha Gray, who submitted a similar design on the same day as Bell, but hours later. Bell also refused to have a telephone in his study, believing it to be an intrusion on his work. Question four. Which scientist accidentally discovered penicillin in nineteen twenty eight Answer Alexander Fleming, the Scottish bacteriologist, returned from vacation to find that a mold Penicillium notatum, had contaminated one of his petri dishes of Staphylococcus bacteria. He noticed that the bacteria weren't growing near the mold, leading to his discovery of the world's first antibiotic. However, it took over a decade and the work of Howard Florey and Ernst Chain to develop penicillin into a usable medicine. Fleming, Flory, and Chain shared the nineteen forty five Nobel Prize in Physiology or Medicine for this groundbreaking work, which has saved countless lives. Question five Which computer scientist invented the World Wide Web? Answer? Tim berners Lee. While working at CERNE, the European Organization for Nuclear Research, in nineteen eighty nine, the British computer scientist proposed a global high hypertext project that would become the World Wide Web. He developed the first web browser, server and web pages at CERN. Critically,

5:09 berners Lee and CERN announced in nineteen ninety three that the web technology would be available to everyone royalty free, allowing it to flourish without commercial restrictions. In two thousand and four, he was knighted by Queen Elizabeth for his pioneering work which transformed global communication and commerce. That concludes today's five Daily Trivia questions.
