Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Cun (unit)

The cun (Chinese: 寸; pinyin: cùn; Wade–Giles: ts'un; Japanese: sun; Korean: chon) is a traditional Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of all fingers side-by-side is three cuns. In this sense it continues to be used to chart acupuncture points on the human body in various uses of traditional Chinese medicine.

The cun was part of a larger system, and represented one-tenth of a chi ("Chinese foot"). In time the lengths were standardized, although to different values in different jurisdictions. (See chi (unit) for details).

In Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in) and is called a "tsun". In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in People's Republic of China and Taiwan it measures 3 ¹⁄₃ cm (~1.312 in).

In Japan, the corresponding unit, sun (寸（すん）, sun), was standardized at ¹⁰⁰⁰⁄₃₃ mm (~3.030 cm, ~1.193 in, or ~0.09942 ft).

Evolution (Baxter novel)

Evolution is a collection of short stories that work together to form an episodic science fiction novel by author Stephen Baxter. It follows 565 million years of human evolution, from shrewlike mammals 65 million years in the past to the ultimate fate of humanity (and its descendants, both biological and non-biological) 500 million years in the future.

Plot summary

The book follows the evolution of mankind as it shapes surviving Purgatorius into tree dwellers, remoulds a group that drifts from Africa to a (then much closer) New World on a raft formed out of debris, and confronting others with a terrible dead end as ice clamps down on Antarctica.

Evolution (Teddy Charles album)

Evolution is an album by jazz vibraphonist and pianist Teddy Charles recorded in 1953 and 1955 for the Prestige label.

Reception

The Allmusic review by Scott Yanow stated "Although somewhat overlooked in the jazz history books, vibraphonist Teddy Charles was for a period an important participant in the early Third Stream movement, using aspects of classical music to revitalize West Coast-style jazz... This session alternates cookers with sensitive ballads and is one of the better recorded showcases for Charles' vibes. Recommended".
