The and that are common developments from the same Old English system. Old English had a definite article se, in the masculine gender, seo (feminine), and þæt (neuter). In Middle English these had all merged into þe, the ancestor of the Modern English word the.
In Middle English, the (þe) was frequently abbreviated as a þ with a small e above it, similar to the abbreviation for that, which was a þ with a small t above it. During the latter Middle English and Early Modern English periods, the letter Thorn (þ) in its common script, or cursive, form came to resemble a y shape. As such the use of a y with an e above it as an abbreviation became common. This can still be seen in reprints of the 1611 edition of the King James Version of the Bible in places such as Romans 15:29, or in the Mayflower Compact. Historically the article was never pronounced with a y sound, even when so written, although the modern, 19th and 20th century pseudo-archaic usage such as "Ye Olde Englishe Tea Shoppe" can be pronounced with a y sound.
Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Although black is sometimes described as an "achromatic", or hueless, color, in practice it can be considered a color, as in expressions like "black cat" or "black paint".
Black can be defined as the visual impression experienced when no visible light reaches the eye. (This makes a contrast with whiteness, the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors.)
Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".
This provides two superficially opposite but actually complementary descriptions of black. Black is the lack of all colors of light, or an exhaustive combination of multiple colors of pigment. See also Primary colors

In physics, a black body is a perfect absorber of light, but, by a thermodynamic rule, it is also the best emitter. Thus, the best radiative cooling, out of sunlight, is by using black paint, though it is important that it be black (a nearly perfect absorber) in the infrared as well.
In elementary science, far Ultraviolet light is called "black light" because, unseen, it causes many minerals and other substances to fluoresce.
On January 16, 2008, researchers from Troy, New York’s Rensselaer Polytechnic Institute announced the creation of the darkest material on the planet. The material, which reflects only .045 percent of light, was created from carbon nanotubes stood on end. This is 1/30 of the light reflected by the current standard for blackness, and one third the light reflected by the previous record holder for darkest substance. 
Summer is the warmest of the four temperate seasons, between spring and autumn. At the summer solstice, the days are longest and the nights are shortest, with day-length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, culture, and tradition, but when it is summer in the southern hemisphere it is winter in the northern hemisphere, and vice versa.
People take advantage of the warmer temperatures by spending more time outdoors during the summer. Activities such as traveling to the beach and picnics occur during summer months. Sports such as cricket, volleyball, skateboarding, baseball, softball, tennis, water polo, and football are played. Water skiing is a u

In the Northern Atlantic Ocean, a distinct tropical cyclone season occurs from 1 June to 30 November.  The statistical peak of the Atlantic hurricane season is 10 September. The Northeast Pacific Ocean has a broader period of activity, but in a similar time frame to the Atlantic.  The Northwest Pacific sees tropical cyclones year-round, with a minimum in February and March and a peak in early September. In the North Indian basin, storms are most common from April to December, with peaks in May and November.  In the Southern Hemisphere, the tropical cyclone season runs from 1 November until the end of April with peaks in mid-February to early March.  
In the interior of continents, thunderstorms can produce hail during the afternoon and evening. Schools and universities typically have a summer break to take advantage of the warmer weather and longer days.
Spinoza contends that "Deus sive Natura" ("God or Nature") is a being of infinitely many attributes, of which thought and extension are two. His account of the nature of reality, then, seems to treat the physical and mental worlds as one and the same. The universal substance consists of both body and mind, there being no difference between these aspects. This formulation is a historically significant solution to the mind-body problem known as neutral monism. Spinoza's system also envisages a God that does not rule over the universe by providence, but a God which itself is the deterministic system of which everything in nature is a part. Thus, according to this understanding of Spinoza's system, God would be the natural world and have no personality.
