Technologies have often been observed to improve exponentially over time. In practice this often means identifying a constant known as the doubling time. Moore’s law is, classically, the empirical observation that the number of electronic components that can be put on a chip doubles every 18 to 24 months. Today it is frequently stated in terms of the number of computations available per unit of cost, a formulation promoted by Kurzweil. Different doubling times describe the rate of advancement in many technologies.
A frequently noted competitor to Moore’s law is known as Wright’s law, which has aeronautical roots. Wright’s law expresses the idea that performance of a technology—price or a quality metric—improves by a constant percentage for every doubling of the total number produced. Does exploration of outer space conform to behavior like Moore’s law or Wright’s law? Our results are broadly consistent with these laws. (More)
Isaac Asimov was one the world’s most celebrated and prolific science fiction writers, having written or edited more than 500 books over his four-decade career. The Russian-born writer was famous for penning hard science fiction in his books, such as that in I, Robot, Foundation and Nightfall. Naturally, his work contained many predictions about the future of society and technology.
We’re not living in space, but the Russian science-fiction author foresaw the rise of intelligent machines and the disruption of the digital age.

The first direct evidence of white dwarf stars solidifying into crystals has been discovered by astronomers at the University of Warwick, and our skies are filled with them.
Observations have revealed that dead remnants of stars like our Sun, called white dwarfs, have a core of solid oxygen and carbon due to a phase transition during their lifecycle similar to water turning into ice but at much higher temperatures. This could make them potentially billions of years older than previously thought.
The discovery, led by Dr. Pier-Emmanuel Tremblay from the University of Warwick’s Department of Physics, has been published in Nature and is largely based on observations taken with the European Space Agency’s Gaia satellite.

SAN DIEGO (Reuters) — Boeing Co unveiled a speedier and higher-flying version of a concept plane on Tuesday aimed at sharply reducing fuel use thanks to its elongated ultra-light wings.
The so-called Transonic Truss-Braced Wing aircraft boasts a 170-foot (52 meter) wingspan that sits atop the fuselage and is braced from underneath by a truss in a design reminiscent of biplanes from the early years of aviation.
The world’s largest planemaker and U.S. space agency NASA have been studying the concept plane for nearly a decade as part of the Subsonic Ultra Green Aircraft Research program. Boeing unveiled a reconfigured model or prototype and artist’s rendering at an aerospace conference in San Diego.

Its spin axis is tilted by a whopping 98 degrees.
Venus takes 243 Earth days to rotate once on its axis – the slowest rotation of any planet – and its rotation is retrograde to its orbital path. Combined with its orbital period, this means that a single solar day on Venus (the time between one sunup to the next) is 117 Earth days.
