Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
A compass rose or compass star, sometimes called a wind rose or rose of the winds, is a polar diagram displaying the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is used on compasses (including magnetic ones), maps (such as compass rose networks), or monuments.
An interdisciplinary field that studies the origins, evolution, distribution, and future of living systems in the universe, encompassing research on organic compounds in space, abiogenesis and extreme-environment adaptation on Earth, the habitability of extrasolar planets, the possible existence of extraterrestrial life, and how humans might be ...
The average height of the high waters of the neap tides occurring at a particular location is called neap high water or high water neaps, and that of the corresponding low waters is called neap low water or low water neaps. [2] Compare spring tide. nearshore The part of a beach between the shoreline and the line at which the waves break. [2 ...
The branches of science, also referred to as scientific fields, scientific disciplines, or just sciences, can be arbitrarily divided into three major groups: The natural sciences ( biology , chemistry , physics , astronomy , and Earth sciences ), which study nature in the broadest sense;
Durotaxis is the directional movement of a cell along a stiffness gradient. Electrotaxis (or galvanotaxis) is the directional movement of motile cells along the vector of an electric field. It has been suggested that by detecting and orienting themselves toward the electric fields, cells can move towards damages or wounds to repair them.
The slope field of =, with the blue, red, and turquoise lines being +, , and , respectively.. A slope field (also called a direction field [1]) is a graphical representation of the solutions to a first-order differential equation [2] of a scalar function.
Karl von Frisch (1953) discovered that honey bee workers can navigate, and indicate the range and direction to food to other workers with a waggle dance.. In 1873, Charles Darwin wrote a letter to Nature magazine, arguing that animals including man have the ability to navigate by dead reckoning, even if a magnetic 'compass' sense and the ability to navigate by the stars is present: [2]
