Optimization: Adjusting something to reach its best state for a specific purpose. We often think that the fastest and strongest options are the best. The fastest way down a slope isn’t a straight line, but a parabola that naturally connects high and low points. A sniper can cause more lethal wounds at 400 meters than at 200 meters. Although the bullet travels faster at 200 meters, the wound size isn’t as large, and at 400 meters, the slower-moving bullet over a longer distance causes more friction as it passes through the wound, resulting in more severe injuries. In every situation, there is an optimal choice suited to the goal. Trial and error are useful for finding this optimization. - Joseph’s “just my thoughts”

Just my thoughts #0707

Milutin Milanković argued that the Earth’s Ice Age was caused by a change in the Earth’s orbit around the sun. This change is said to affect the inclination of the Earth’s northern and southern hemispheres and reduce the amount of solar radiation . However, the main reason is believed to be that summer isn’t hot enough. The ice kept accumulating as summer passed, and winter arrived before all the ice could melt. Even in our lives, things we neglect tend to build up and lead to big problems. Small, untreated chores can produce significant results over time. Good luck or bad luck, maybe that’s all there is. - 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”
