[ 1 ] [ 2 ] He wrote Science and Human Transformation , a book about concepts such as subtle energies beyond the four fundamental forces , which he believes act in concert ...
A tiller is a shoot that arises from the base of a grass plant. The term refers to all shoots that grow after the initial parent shoot grows from a seed. [1] [2] Tillers are segmented, each segment possessing its own two-part leaf. They are involved in vegetative propagation and, in some cases, also seed production.
Agriculturalism, also known as the School of Agrarianism, the School of Agronomists, the School of Tillers, and in Chinese as the Nongjia (simplified Chinese: 农家; traditional Chinese: 農家), was an early agrarian Chinese philosophy that advocated peasant utopian communalism and egalitarianism.
Modern agricultural science has greatly reduced the use of tillage. Crops can be grown for several years without any tillage through the use of herbicides to control weeds, crop varieties that tolerate packed soil, and equipment that can plant seeds or fumigate the soil without really digging it up.
The plant Arabidopsis thaliana is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. [41] Space stations or space colonies may one day rely on plants for life support .
The Museum of Life Sciences is a life science and natural history museum that is part of King's College London in London, England. It is housed on the Guy's Campus, adjacent to the Gordon Museum of Pathology in the Hodgkin Building. It was founded in 2009 and is the first new museum in King's College for over 100 years. [1]
Tiller blocked by two lines Stern compartment containing the tiller of Swedish 17th century warship Vasa. A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder.
The hoedad, hoedag or hodag is a hoe-like tool used to plant trees. [13] According to Hartzell (1987, p. 29), "The hoedag [was] originally called skindvic hoe... Hans Rasmussen, legendary contractor and timber farm owner, is credited with having invented the curved, convex, round-nosed hoedag blade which is widely used today" (emphasis added). [14]
