Thomas Edison
Thomas Edison and Nikola Tesla were two great inventors and innovators who ushered in the age of electricity. Their contributions laid the foundation for the electric systems we use today. However, they had significantly different approaches and philosophies regarding electrical technology, which led to the historic "War of Currents."
As previously explained, Thomas Edison developed the light bulb, phonograph, and power supply systems. One of his greatest contributions was the commercialization of the direct current (DC) electrical system. Edison established the first commercial power plant in New York, where he began supplying DC electricity to homes and industrial sites.
Nikola Tesla, a Serbian-American inventor and electrical engineer born in Croatia, is famous for developing the alternating current (AC) electrical system. Unlike Edison, Tesla believed that AC electricity was more efficient and suitable for long-distance transmission. His research led to inventions such as the electric motor, AC power transmission system, Tesla coil, and the foundations of wireless communication.

Spending a night observing celestial bodies in nature provides a unique and memorable experience for all participants. The lunar rover displayed in the corridor connecting the exhibition halls caught my attention. There are three types of telescopes on display : the Galilean telescope , the Keplerian telescope , and the Newtonian telescope . Among these, the Galilean telescope, even when you try to look through it from various angles, doesn’t show things clearly. The reason isn’t that the telescope is broken. Rather, it’s because this telescope was made exactly in the same way the Italian astronomer Galileo constructed his telescope 411 years ago in 1609 for his astronomical observations. This type of telescope is called a Galilean telescope , and to overcome its inconvenient observation difficulty, Kepler designed the two Keplerian telescopes that are displayed in the center. The museum has installed both types of telescopes side by side, allowing visitors to compare the two and experience the differences in observation. Detailed descriptions of each telescope’s characteristics are displayed in front of the telescopes. Additionally, there is an exhibit on Bohyunsan Optical Astronomy Observatory’s main telescope , which is also featured on the 10,000-won banknote —a frequent subject in Korean astronomical observation displays. The 10,000-won bill, which we commonly use, features some of Korea’s proud astronomical observation devices. Among them are the Cheonsang Yeolcha Bunyajido (a star chart including the Big Dipper ), the Armillary Sphere (Honcheonui) , and next to it, the Bohyunsan Observatory’s main telescope . A 1/6 scale model of the Bohyunsan main telescope is also displayed in front of the panel. This model represents the Bohyunsan Optical Astronomy Observatory’s main telescope , which is featured on the back of the 10,000-won bill. It is the largest telescope in Korea with a 1.8-meter aperture reflector , completed in 1996. It gathers tens of thousands of times more light than the naked eye can. Opposite the telescopes, there is a display panel featuring the Cheonsang Yeolcha Bunyajido , a star chart that offers a glimpse into the astronomical knowledge of our ancestors. (The original is housed at the National Palace Museum of Korea .) The cosmic distance comparison panel highlights the immense scale of the universe, comparing distances between celestial bodies. Alongside this, another exhibit focuses on the formation of Earth , detailing how our planet was born from cosmic dust and gases over billions of years, eventually becoming the life-sustaining planet we know today. Types of Electromagnetic Waves and Infrared Camera Experience Exhibit There are many different types of light, including gamma rays , X-rays , ultraviolet rays , visible light , infrared rays , microwaves , and radio waves —all of which are forms of electromagnetic waves. However, we can only see visible light . At this exhibit, you can use an infrared camera to capture infrared light, a type of light that our eyes cannot detect. Such displays are commonly found in science museums, but what made this one unique was not simply standing in front of the infrared camera to observe temperature differences based on body heat. What was particularly interesting here was the opportunity to use a cooling rod located to the left of the exhibit. After holding the cooling rod with one hand for 10 seconds, you raise both hands in front of the infrared camera to compare the temperature differences displayed on the screen, making the experience even more engaging! The panel that caught attention: "Star Lovers" . It features both domestic and international scientists, though most people are only familiar with the names of the foreign scientists. However, when you look closely, you'll realize that Korea’s astronomical knowledge, which began with ancient astronomy, is by no means inferior. (left) You can view real-time footage of Earth captured from the International Space Station (ISS) . There's also a display showing how the space shuttle is transported.
