What does a weather vane do and how does it work?
A wind vane has a horizontal bar (sometimes it's a tube or shaft), which is mounted upon a circular pivot point that allows the bar to freely spin around in a horizontal plane pointing in any direction of the wind. A tail is placed at one end of the bar and the other end is used as the direction indicator (the pointer). The tail has more wind resistance than the small pointer, so a wind will always force the tail. This points the indicator (the pointer) into the wind to correctly show the wind direction. Often this pivot point is placed just slightly close toward the point than the tail. This adds leverages to the mechanical energy of the wind force placed upon the tail, which allows the indicator to correctly point into the wind even with low wind speeds. A windsock, often seen at airports or near helicopter pads points the opposite way of a weather vane - a windsock points into the direction where the wind is going, not from where it came like the wind vane.The wind vane rotates freely on a veritical rod and becomes aligned by the direction of the wind.
Who came up with the Coriolis Effect?
Obviously a scientist named Coriolis or someting similar. By the way another scientist named Ferrell ( l9th century ) working for the Coast and Geodetic survey labs came up with an identical theory accounting for the direction of cyclones in different directions in the northern and southern Hemispheres. Mr. Ferrell also invented a tidal-prediction machine using mechanical clockwork- one wonders if one of these survives as a museum piece, do not confuse with Tide timers superimposed over some maritime clocks. The name of the effect-and force has no connection with Burlesque actress Ann Corio.
What is the main direction of stress on blocks of rock at normal faults reverse faults and strike-slip faults?
At normal faults, the main direction of stress is extensional, with the hanging wall moving down relative to the footwall. At reverse faults, the main direction of stress is compressional, with the hanging wall moving up relative to the footwall. In strike-slip faults, the main direction of stress is horizontal, with the blocks of rock sliding past each other horizontally.
How did alkaline earth metals get their names?
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
What came after the Stuart Period?
