Latest Pendulum Stories
A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position.
A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability.
Contemporary Heaven now stocks two new wall clocks from the Spanish designer brand Balvi, who provide funky modern wall clocks and home accessories.
In a groundbreaking new study, physicists from the University of California, Berkeley have used atomic matter to measure time.
An optical clock with neutral strontium atoms is considered one of the top candidates for the definition of a "new" second. The probabilities have increased considerably, since its frequency will now be determined more accurately (probably by an order of magnitude).
A clock accurate to within a tenth of a second over 14 billion years – the age of the universe – is the goal of research being reported this week by scientists from three different institutions.
As time passes, new technology evolves in order to keep time. Soon the trusty atomic clock may be replaced by a nuclear clock, which keeps time to 1/20th of a second in 14 billion years.
A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena.
Researchers have found that an atomic clock at the U.K.'s National Physical Laboratory (NPL) has the best long-term accuracy of any other clock in the world.
An astronomical clock is a clock with special mechanisms and dials to display astronomical information. This information can include everything from the relative position of the sun and the moon to major planets to zodiacal constellations. The term Astronomical clock is loosely used to refer to any clock that shows astronomical information. The clock could include the location of the sun and the moon, age and phase of the moon as well as other astronomical data. However, it should not be...
