There are two primary approaches to creating something: bottom-up design and top-down design . Top-down design is often seen in architecture. People do not build bricks randomly; instead, they follow the design drawings created by the architect. This method executes a plan that has already been established. When asked why something is built in a certain way, the answer is usually that the blueprint dictates its design. Conversely, bottom-up design does not start with a fixed goal, but rather involves setting and implementing small, actionable rules. For example, termite nests follow this approach. Small termites have a simple rule: to pile up soil. They do this without knowing the reason, but over time, the finished structure is remarkable and sophisticated. The appearance of the Sagrada Familia church , designed by Antoni Gaudà and still under construction, closely resembles a termite nest, differing only in size. Setting goals and planning is one way to create, but actual achievem...
Here a product is being made by only three countries, South Korea, China, and Japan. It's not a semiconductor but a nail clipper. You might think that a nail clipper is not a big deal, but it's not as simple as that. Nail clippers are a combination of all sorts of advanced technologies. In the 1980s, South Korea could produce submarines and battleships, but they did not possess the technology to produce nail clippers. When the upper and lower teeth are in mesh, the chink must be 0.1 to 0.2 millimeters. When perfect engagement, the nail is not cut properly on the contrary, the outrange of this tolerance, is cut out coarsely. Today, thanks to technological advances, South Korea has been able to narrow this chink to between 0.05 and 0.08 millimeters. South Korea, to achieve this goal, produces a special steel called "15CM" through POSCO which is specially made for this nail clipper. Many different advanced technologies are combined in this tiny nail clipper. Don't ...
