The Zhoubi Suanjing is one of the oldest Chinese mathematical texts. "Zhou" refers to the ancient Zhou dynasty. The book is dedicated to astronomical calculation. "Suan Jing" or "classic of arithmetics" were appended in time to honor the achievement of the book in mathematics. This book dates from the period of the Zhou dynasty, yet its compilation and addition of materials continued into the Han dynasty, it is an anonymous collection of 246 problems encountered by the Duke of Zhou and his astronomer and mathematician, Shang Gao. Each question has stated their numerical answer and corresponding arithmetic algorithm; this book contains one of the first recorded proofs of the Pythagorean Theorem. Commentators such as Liu Hui, Zu Gengzhi, Li Chunfeng and Yang Hui have expanded on this text. At this early point in Chinese history the model of the ancient Chinese equivalent of Heaven, 天 Tian, was symbolized as a circle and the earth was symbolized as a square. In order to make this concept understood the adopted symbol of the heavens was the ancient Chinese chariot.
The charioteer would stand in the square body of the vehicle and a "canopy", the equivalent of an umbrella, stood next to them. The world was thus likened to the chariot in that the earth, the square, was where the charioteer stood, heaven, the circle, was suspended above them; the concept has thus been termed "Canopy Heaven", 蓋天. The populace began to turn away from the "Canopy Heaven" concept in favor of the concept termed "Spherical Heaven", 渾天; this was due to the fact that the people were having trouble accepting heaven's encompassment of the earth in the fashion of a chariot canopy because the corners of the chariot were themselves uncovered. In contrast, "Spherical Heaven", has Heaven, Tian surrounding and containing the Earth and was therefore more appealing. Despite this switch in popularity, supporters of the Gaitian "Canopy Heaven" model continued to delve into the planar relationship between the circle and square as they were significant in symbology. In their investigation of the geometric relationship between circles circumscribed by squares and squares circumscribed by circles the author of the Zhoubi Suanjing deduced one instance of what today is known as the Pythagorean Theorem.

As of November 2019, 300 venues have hosted at least one match of women's One Day International cricket. One Day Internationals were the second form of international women's cricket to be introduced, after Test matches; the first ODIs were played at the 1973 World Cup, over 900 ODIs have been played since, as opposed to nearly 150 Test matches and just over 300 Twenty20 International games. This imbalance in the number of games played in each format is reflected in the number of venues used – 73 grounds have been used for women's Tests, while 163 venues have hosted T20Is. Twenty-seven countries have hosted at least one women's ODI match. Note: venues marked with a dagger have had matches played on multiple grounds within the venue, but are counted as a single ground for the purposes of this list.

Sophora tomentosa known as necklacepod, yellow necklacepod, as silver bush, is a pantropical shrub or small tree in the family Fabaceae. It ranges in height from 4 to 10 feet and occurs in coastal conditions and near wetlands; the common name Necklacepod is derived from the characteristic string of seed pods that develop after its yellow flowers germinate into seeds. Necklacepod is a nectar plant for bees, in parts of the Americas hummingbirds as well, it is suggested for use by native plant enthusiasts in Florida as a good landscape plant for xeriscaping but it only occurs in coastal counties in the central and southern part of the state, while related varieties occur in Texas, the Caribbean. The variety of Necklacepod growing in Australia is considered an endangered species in some areas due to the clearing of coastal habitat and displacement by invasive species. In Sri Lanka, the plant is known as Moodu Murunga; the inedible pod has some similarities to the Murunga pod. It has been used to make fish poisons and spider repellents etc. esp in Africa.

Garden Walk Buffalo is a free, self-guided garden tour of more than 400 Buffalo, New York, USA, residential urban gardens. The event is held annually on the last full weekend of July; the event attracts thousands of visitors from across the U. S. and Canada. Garden Walk Buffalo extends from the Frederick Law Olmsted-designed Delaware Park to the urban core of Buffalo, New York. Most participating gardens are private, but community spaces, corporate gardens, religious institutions' gardens are included, it is noncompetitive, with no prior judging of gardens. The work of organizing and managing the event is done by the volunteers of Gardens Buffalo Niagara, a non-profit group. Financial support comes from contributions from participants and corporate sponsorships. Since 2005, Garden Walk Buffalo has provided Neighborhood Beautification grants for community gardening projects within the Garden Walk area; the group produced a Garden Walk Buffalo coffee table book and DVD in 2006, published by Buffalo Heritage Press, in its second printing.
In 1993, Buffalo, NY residents Marvin Lunenfeld and Gail McCarthy attended the Sheffield Garden Walk in Chicago, IL and decided it was a concept that could work well in Buffalo. They presented the idea to the members of the Norwood/West Utica Neighborhood Association, which represented their Westside community, by the summer of 1995 a group of volunteers from that organization had set up the basic structure for the first Buffalo Garden Walk, held on July 15 and 16, 1995; the event was open to anyone in the area. Twenty-nine gardens were entered, most in the area enclosed by West Ferry Street, Richmond Avenue, Summer Street, Elmwood Avenue; the front porch of Lunenfeld and McCarthy's home was the headquarters for the event for its first five years. In the intervening years, Garden Walk has grown beyond its original scope; the number of gardens participating in the Garden Walk has increased every year, growing to 355 in 2010, making the event one of the largest of its kind in the United States.
