Prince Philip was born Prince Philip of Greece and Denmark. There were two pages: HRH Prince William of Gloucester (aged 5) and HRH Prince Michael of Kent (aged 5). The Queen's wedding dress was designed by Sir Norman Hartnell. As an owner and breeder of thoroughbreds, she often visits other race meetings to watch her horses run, and also frequently attends equestrian events. She attends the Derby at Epsom, one of the classic flat races in Britain, and the Summer Race Meeting at Ascot, which has been a Royal occasion since 1911. The Queen's horses won races at Royal Ascot on a number of occasions. To formally greet the Queen men should perform a neck bow (from the head only) whilst women do a small curtsy.

Otto Wolff, from 1900 to 1909, produced the Reichsanstalt-type of resistance standards used at the National Bureau of Standards (NBS.) At the turn of the last century, many precision measurements had to be calculated because the measurement couldn't be made directly since many of the instruments we take for granted today hadn't been developed.
A known precision resistance allowed one part of the equation to be selected and the remainder was then calculated.
