  • Carrara Marble - Carrara marble is a type of white or blue-grey marble quarried in the Carrara region of Tuscany, Italy. It is prized for its beauty, durability and the ease with which it can be worked. The marble has been used for thousands of years for sculptures and architectural details, and was particularly popular during the Renaissance period. Some of the most famous sculptures in the world, such as Michelangelo's David, were carved from Carrara marble. It is also widely used in the construction of buildings, floors, and countertops, both indoors and outdoors. This marble is known for its unique veining which gives it a distinctive look, and it's a popular choice for interior design, especially bathrooms and kitchens.
  • Pendulum - The pendulum was discovered around 1602 by Galileo Galilei, and was adopted for time keeping by the Dutch mathematician and natural philosopher, Christiaan Huygens, who excelled in astronomy, physics, and horology.

    The pendulum comprises a metal rod usually of brass or steel with a metal disk, known as a bob, at the end. The movement of the pendulum is driven by weights or a spring, and as a pendulum swings in a regular arc, it was found accuracy could be controlled to within a few seconds a week.

    Timekeeping can be adjusted by changing the height of the bob on the rod, making the pendulum either swing slower or faster.

    The disadvantage of the pendulum was that changes in temperature also changed the length of the pendulum, interfering with the accuracy of the clock, and so in the 18th century two types of mercurial pendulums were invented which countered the movement in the steel rod.

    The pendulum was the world's most accurate timekeeping technology until the invention of the quartz clock, regulated by a quartz crystal, in 1927.
