The Story of the Largest Lens Ever Made
by chm

The article discusses the largest lens ever made, which was a 40-foot-wide correcting lens for the 200-inch telescope at Palomar Observatory. It also covers the discovery of the fifth moon of Saturn by John Herschel in 1834 and the first jet-powered aircraft designed by Henri Coanda in 1923. The article also mentions the first rocket-powered aircraft, the V- 2, which was designed by Wernher von Braun and flew in 1942. Finally, the article discusses the Hubble Space Telescope, which was launched in 1990, and the James Webb Space Telescope, which is scheduled to launch in 2018.

The World's Biggest Telescopes
by chm

The article covers the biggest telescopes in the world in each of the three main categories: optical, radio, and infrared. The Gran Telescopio Canarias is the largest optical telescope, the Five hundred meter Aperture Spherical Telescope is the largest radio telescope, and the James Webb Space Telescope is the largest infrared telescope. There are over 10,000 known exoplanets, and the average person can see about 2,000 stars with the naked eye. A telescope can magnify objects up to 2,000 times their actual size.

How quantum computers work and why they're so powerful
by chm

Quantum computers are able to solve certain problems much faster than classical computers because they can take advantage of the fact that a quantum bit (qubit) can represent both a zero and a one simultaneously. Although quantum computers are still in their early stages of development, they have great potential for solving complex problems in a variety of fields in the future.
