Wagons are believed to have been first created in western Asia around 3500 BC. Initially, because the wheels were disc-shaped, they were pulled by cattle due to their heaviness. However, after the invention of spoke wheels, horses could pull the wagons because they were lighter. Naturally, there was a big difference between the speed of a wagon pulled by cattle and one pulled by a horse. This led to a decrease in travel time. A minor adjustment to the spoke design sparked a significant change in human civilization. Nearly all innovations start small, but even the tiniest change can have enormous consequences. Many unseen factors contribute to this innovation in our lives. - Joseph’s “just my thoughts”
In September 1999, NASA’s unmanned Mars climate probe “MCO” exploded in Mars’ orbit. Manufacturer Lockheed Martin set up the data unit as a “yard,” but NASA mistook it as a “meter.” The MCO entered the atmosphere of Mars 100 km below the original orbit and exploded in friction. Communication error had blown away $ 125 million. With this opportunity, NASA decided that the units used in space development were “meters”. A slip of the tongue in business doesn’t end just a mistake accidentally. It must undoubtedly damage the “cash flow”. - Joseph’s “just my thoughts”
