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.
During the 18th and 19th centuries, Scottish military personnel helped to bring the game of golf to the British colonies. Clubs such as the Royal Calcutta Golf Club and the Royal Blackheath Golf Club can trace their roots to the spread of golf in the 18th and 19th centuries. The Royal Calcutta Golf Club is the oldest golf club outside of the British Isles, and they serve as a reminder of the history of golf's beginnings.
