IDEA EXTRACTED FROM:
Sudoku has been identified as a classic meme - a mental virus that spreads from person to person across national boundaries. The puzzle is using our brains to multiply across the world.
Sudoku consists of 81 squares, divided into nine blocks of nine squares each. Some squares contain a number. The goal is to fill in the empty squares so that the figures 1 to 9 appear just once in every row, column, and individual block. The puzzle does not require general knowledge or mathematical skill.
In 1997, Wayne Gould, a man from New Zealand, was visiting Tokyo. While he was browsing a bookstore, he saw the squares and felt tempted to fill them in. Over the next six years, he developed a computer program that instantly makes up Sudoku puzzles.
Gould's wife published one of his puzzles in the local newspaper. It spread to Britain and was published in the Times, where it took off.

The current CEO of Tesla wasn’t the founder of the company and joined in 2004. His investments and lobbying provided the company with much-needed traction to build the first completely electric sports car, called the Roadster, which went into production in 2008.
The futuristic electric sports car was a technical marvel but out of reach for most people at USD 100,000, and also had a slow charge.
