CPUs make it look like multiple programs are running simultaneously by scheduling them to alternate execution at short time intervals. It does this by using work queues, interval execution, and alternating times, and the operating system performs context switching to store and recall the state of programs. As the number of programs registered in the work queue increases, the waiting time...
This article discusses whether rape is an evolutionary adaptation, exploring whether it helps individuals survive and reproduce, and whether it is a trait that has been subject to natural selection. Can rape be an adaptation? The topic may be uncomfortable to hear or even frowned upon, but as someone who has always been interested in the purpose of human behavior, I find it...
European art in the 13th century was influenced by Byzantine art, which used flat, static religious imagery, but Giotto di Bondone introduced three-dimensionality and animation through realistic observation and perspective to vividly depict human emotion. His innovations became the foundation of Renaissance art. In the 13th century, European art was influenced by Byzantine art. Byzantine...
Shipbuilding and marine engineering covers a wide range of fields, not only ships but also offshore plants, which play an important role in marine resource development, environmental protection, research, etc. It is essential to understand the importance and characteristics of offshore plants. When I tell someone that I’m majoring in shipbuilding and marine engineering, they usually...
The discovery of the cosmic background radiation by Penzies and Wilson in 1965 has had a profound impact on modern astronomy and cosmology, as it strongly supports the Big Bang cosmology and provides important clues to the origin and evolution of the universe. In 1965, Penzies and Wilson, researchers at the Bell Telephone Company, were using antennas to search for long-distance radio and...
When shooting with a digital camera, there are two technologies that minimize shake caused by hand shake or movement: optical image stabilization (OIS) and digital image stabilization (DIS). OIS physically moves the lens and sensor to compensate for shake, while DIS uses software to correct shake after the shot is taken. These technologies are used in a wide range of devices, including...
More than just a sense of smell, the sense of smell protects us by detecting dangers like spoiled food and gas leaks. It also plays a role in many aspects of our lives, with certain odors triggering memories and emotions, affecting our social interactions and health. It’s because we have a sense of smell that we can easily recognize spoiled food and gas leaks. As such, the sense of...
A work of art is composed of compositional elements such as point, line, surface, form, and color, and compositional principles such as unity, balance, and proportion, which have a visual and psychological effect on the viewer. Unity is divided visually and intellectually, and is achieved by methods such as adjacency, repetition, and continuity. A work of art contains a combination of...
Necking and strain hardening, the process of deformation and failure of a material, shows how stresses are concentrated in a specific part of the material, weakening it and eventually damaging the entire structure. This phenomenon can be used as an analogy to explain the recent ‘cutlery’ controversy and social inequality in South Korea. Recently, South Korea has been hotly...
