Various sensors can be attached to (or included in) multimeters to take measurements such as: 1  light level. 2  sound pressure level. 3  acidity/alkalinity(pH) 4  relative humidity. 5  very small current flow (down to nanoamps with some adapters) 6  very small resistances (down to micro ohms for some adapters)
The 1800s: Modern Golf Takes its Form: The 19th century is considered by many to be the period when the truly modern game emerged. The changes that primarily spurned this modernization were to the equipment of the game. Up to 1848, golf balls, as previously stated, were featheries, made of feathers and leather.
Although the first noted use of the word par in golf was in Britain and predates the bogey, today's rating system does not and the par standard was not further developed until later. It was the Ladies Golf Association, who, from 1893, began to develop a national handicapping system for women. It was largely in place by the end of the Century.
