In this blog post, we will examine how the wave nature of electrons is localized in solids through various types and physical principles. Wave nature of electrons in solids and localization phenomenon Solids are three-dimensional structures formed by atoms arranged in relatively fixed positions, and are divided into regular crystals and irregular amorphous solids depending on the...
In this blog post, we will examine why signals can be transmitted accurately despite noise in wireless communications through modulation methods, reliability, and bandwidth concepts. Analog mobile phones first appeared in 1981. At that time, mobile phones were simply devices for voice calls, and they were quite large and heavy. Then, in 1991, 2G communications, which converted the existing...
In this blog post, we will examine the possibilities and ethical issues surrounding genetic engineering technology and its potential to cure human diseases and improve quality of life. What if we were born knowing our diseases, physical abilities, and talents through DNA testing? Now that we are in the 21st century, this is no longer the stuff of science fiction. In the 1970s, the Human...
In this blog post, we take an in-depth look at the ethical issues and social implications of designer babies born through genetic engineering, as well as the future we will face. On October 29, 2000, a test-tube baby named Adam Nash was born in Colorado, USA. The embryo implanted in Mrs. Nash’s womb was found to have no genetic defects that cause Fanconi anemia through pre...
In this blog post, we will examine why the endless debate about genetics and environment continues, and present a new perspective that will help us escape from this fatigue. Introduction A, who had always struggled with math, was studying math in the classroom during break time to prepare for the college entrance exam. Suddenly, his friend B came over and said, “Hey, I saw on the news...
In this blog post, we will look at various examples to explain why ethical guidelines are essential in this era of rapid advances in genetic engineering. In April 1953, biologists James Watson and Francis Crick discovered the structure of DNA. This was a great discovery that marked the beginning of genetic engineering. Since then, Dolly, a cloned sheep with identical DNA, was created by...
In this blog post, we consider whether it would be right for humanity to design children through genetic engineering if such a technology became available. With the advancement of genetic engineering technology, in the near future, it may be possible to manipulate a child’s genes to make them taller or smarter. Genetic engineering of children refers to the manipulation of a...
In this blog post, we acknowledge the dangers and limitations of nuclear power plants, but examine the need for their continued existence, focusing on their energy efficiency, economic viability, and potential as an environmental alternative. On March 11, 2011, a magnitude 9 earthquake and tsunami struck Fukushima, Japan, destroying nuclear power plants and causing a massive radioactive...
In this blog post, we take a multifaceted look at whether the construction of additional nuclear power plants, which is gaining attention as a realistic solution to climate change, is a safe choice or a challenge that poses new risks. We have reached an era where we cannot live without electricity and energy. Energy is generated by power plants. South Korea supplies electricity to a...
In this blog post, we take a multifaceted look at whether the construction of additional nuclear power plants is a safe and realistic choice in South Korean society, which is in desperate need of energy independence. The controversy surrounding the 7th Basic Plan for Electricity Supply and Demand announced by the Ministry of Trade, Industry and Energy some time ago continues to rage. This...
