The Golden Dome missile defence system was announced by U.S. President Donald Trump on May 20, 2025, as a comprehensive shield to protect the U.S. homeland from advanced missile threats. Initially referred to as an “Iron Dome for America” in a January 27, 2025, executive order, it was rebranded as the “Golden Dome” in February…
A semiconductor microchip, often referred to as an integrated circuit (IC) or simply a “chip,” is a small electronic device made from semiconductor materials (primarily silicon) that integrates millions to billions of electronic components—such as transistors, resistors, capacitors, and diodes—onto a single substrate. Microchips are the cornerstone of modern electronics, enabling compact, efficient, and powerful…
Semiconductors are materials that have electrical conductivity between that of conductors (like metals) and insulators (like glass). This unique property arises due to their energy band structure, specifically the presence of a small energy gap (bandgap) between the valence band (where electrons are bound to atoms) and the conduction band (where electrons can move freely…
Computers have become the backbone of modern civilization, powering everything from smartphones to space exploration.

Radioactive carbon dating, commonly known as radiocarbon dating or carbon-14 dating, is a scientific method that has revolutionized our understanding of the past. By measuring the decay of the radioactive isotope carbon-14 (¹⁴C) in organic materials, scientists can determine the age of artifacts, fossils, and environmental samples up to about 55,000 years old. Developed in…
