    A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College and Santa Clara University. Research describing the effect shows that superposition—the ability of an atom to exist in more than one state at the same time—leads to a correction in atomic clocks known as "quantum time dilation." The research, published in the journal Nature Communications, takes into account quantum effects beyond Albert Einstein's theory of relativity to make a new prediction about the nature of time. In the early 1900s, Albert Einstein presented a revolutionary...
  • Why is Jeff Bezos building a giant ‘millennial' clock inside a mountain? [$42M!]

    The Long Now Foundation’s clock is a symbol for multi-generational thinking Jeff Bezos wants us all to be good ancestors. The Amazon supremo just tweeted that installation has begun on one of his pet projects of the last decade, the 10,000 Year Clock, also called the Clock of the Long Now. Designed to stay accurate for that huge time period, the giant clock will tick once a year, moving its century hand every 100 years, and send out a cuckoo once a millennia – just 10 times in its life. And it costs US$ 42 million. What is Bezos thinking?...
