Featured Article: Tritium
Tritium (chemical symbol T or 3H) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (the most abundant hydrogen isotope) contains one proton and no neutrons. Tritium emits low-energy beta radiation that cannot penetrate human skin, so this isotope is dangerous only if inhaled or ingested. The properties of tritium make it useful for various applications: self-illuminating watches, compasses, key chains, and gun sights for firearms.
Popular Article: Chinese dragon
The Chinese dragon is a Chinese mythical creature that also appears in other East Asian cultures, and thus is also sometimes called the Oriental (or Eastern) dragon. Unlike the Western dragon of Europe that is representative of evil, the many eastern versions of the dragon are powerful spiritual symbols, representing seasonal cycles and supernatural forces. The Chinese dragon is easily recognizable for its long serpentine body that is generally wingless, and its anthropomorphic face, complete with beard.
