Cells Cells are the fundamental structural and functional units of living organisms. All organisms, whether unicellular (such as bacteria and yeast) or multicellular (such as plants, animals, and humans), are composed of cells. Cell biology is the scientific discipline dedicated to studying cell structure, function, and behavior. Through advancements in microscopy, cell culture, and molecular […]

Fungi Fungi are eukaryotic, spore-producing, chloroplast-lacking organisms. They include molds, yeasts, mushrooms, and other well-known fungi. As of 2024, approximately 150,000 species of fungi have been discovered and documented by the scientific community, including yeasts, molds, and various types of mushrooms. Fungi are classified in a separate kingdom from animals, plants, and other eukaryotes. Their […]

Morse Code Morse code is a coding system used for transmitting textual information through a series of signals comprising varied lengths (commonly referred to as “dots” and “dashes”) that represent letters, numbers, and punctuation marks. Developed by American inventor Samuel Morse and Alfred Vail in the 1840s, it was initially employed for telegraphic communication. In […]

Gravity Gravity is a fundamental force of nature, where objects with mass attract each other. Universal Gravitation refers to the attractive force between any two objects or particles, which is related to their mass product and distance. Gravity is one of the most common forces in nature, with an infinite range, although it weakens rapidly […]

Geomagnetism Geomagnetism refers to the magnetic field surrounding the Earth, also known as the Earth’s magnetic field. It is generated by natural magnetic phenomena within the Earth, which can be perceived as a magnetic dipole, with one pole located near the geographic North Pole and the other near the geographic South Pole. The geomagnetic field […]

South Sea(南海): In Chinese, it is pronounced as: nán hǎi，Written as: The term “South Sea” can refer to different concepts. In the novel *Journey to the West*, it refers to the ashram of Guanyin Bodhisattva. In modern times, located in the southern part of mainland China, it is part of the western Pacific Ocean and […]

Coal Coal is a vital fossil fuel primarily composed of carbon, hydrogen, oxygen, sulfur, and nitrogen. It is formed through geological processes from the long-term burial of plant remains under high temperatures and pressures. The process of coal formation is known as coalification, which typically spans millions of years. Depending on its composition and combustion […]

3D Printing 3D printing, also known as additive manufacturing, is a technology that fabricates three-dimensional objects by incrementally adding material layer by layer. In contrast to traditional subtractive manufacturing methods (such as cutting and milling), 3D printing constructs products through the accumulation of materials. The applications of 3D printing are diverse, encompassing manufacturing, healthcare, architecture, […]

The Goldbach Conjecture The Goldbach Conjecture is a well-known unsolved problem in number theory. Its core content is that any even number greater than 2 can be expressed as the sum of two prime numbers. For instance, 4 = 2 + 2, 6 = 3 + 3, 8 = 3 + 5, and so on. […]

Ventilators A ventilator is a medical device designed to assist patients in maintaining normal respiratory function, particularly when they are experiencing breathing difficulties or respiratory failure. Ventilators mechanically deliver oxygen while expelling carbon dioxide, ensuring patients receive adequate oxygen supply. The basic operating principle of a ventilator involves providing positive pressure to facilitate airflow into […]

Lightning Lightning is a natural phenomenon accompanied by flashes of light and thunder, which is the process of neutralizing electric charges in the air. Lightning usually occurs in strong convective weather, especially in summer. It forms in cumulonimbus clouds with vigorous convection, where electric charges accumulate inside or between the clouds, creating a potential difference. […]

Gold Gold is a chemical element with the symbol Au (derived from the Latin word “aurum”) and atomic number 79. It is a precious metal with unique physical and chemical properties. Gold has a bright yellow color and a good luster. Its color is relatively unique among metals and is one of the most eye-catching […]

Solvents Solvents are substances that can dissolve other materials (referred to as solutes) to form a homogeneous solution. Solvents are typically liquids but can also exist as gases or solids. Depending on their molecular structure, solvents can be classified into polar solvents (such as water and alcohols) and nonpolar solvents (such as petroleum ether and […]

General Relativity General relativity is a theory about space-time and gravity proposed by Albert Einstein in 1915. It is an extension of special relativity and mainly deals with the effects of gravity, providing a theoretical description of how gravity influences the structure of space-time. In general relativity, gravity is regarded as the curvature of space-time, […]
