Nature wiki:
>For alternative meanings, see nature (disambiguation). Nature (also called the material world, the material universe, the natural world, and the natural universe) is all matter and energy, especially in its essential form. Nature is the subject of scientific study, and the history of the concept is linked to the history of science. The English word derives from a Latin term, natura, which was in turn a translation of a Greek term, physis (ÏÏÏιÏ). Natura is related to the Latin words relating to "birth", while physis relates to Greek words relating to "growth". In scale, "nature" includes everything from the universal to the subatomic. This includes all things animal, plant, and mineral; all natural resources and events (hurricanes, tornadoes, earthquakes). It also includes the behaviour of living animals, and processes associated with inanimate objects - the "way" that things change.

Summer wiki:
>For other uses, see Summer (disambiguation). Summer is a season, defined by convention in meteorology as the whole months of June, July, and August, in the Northern hemisphere, and the whole months of December, January, and February, in the Southern hemisphere. In some Western countries, the first day of summer (in the Northern hemisphere) falls either on, or around, June 21 or on June 1 (the former is the astronomical start; the latter, the meteorological). Summer is commonly viewed as the season with the longest (and warmest) days of the year, in which the daylight predominates, through varying degrees. In the northern latitudes, twilight is known to last at least an hour, sometimes leading to the famous white nights found in St. Petersburg and Scandinavia.
