NASA To Launch Deep Space Atomic Clock For Precise Timing Off-World
Image Credit: NASA/JPLNASA’s Deep Space Atomic Clock (DSAC) is one of the most important timing instruments ever developed, and it will serve as a foundation for long-distance travel and communication off our home planet, Earth. How accurate is it? Accurate to one second every 9,000,000 years. Having said that, understanding the larger importance of precision timing instruments requires education in a number of areas, including physics, navigation and, of course, horology. For example, it is not obvious to many people that a precise clock is necessary for precise navigation. Also, many people don’t immediately appreciate that the effects of relativity change how the measurement of time is experienced in two different points in space. Suffice it to say that long-distance space travel and communication require extremely precise, local timing machines.Image Credit: NASA/JPLAtomic clocks (history on best watches here) are the most precise form of timing instruments currently kn
Bremont Supermarine Waterman Limited Edition Watch Hands-On
The first instructions during our breathing exercise with Mark Healey-a world renowned freediver, big-wave surfer, and ocean environmentalist-were?"Breathe in and fill your butt with air."The breathing exercises were a quick intro to some of Mark's breathing techniques that he uses to prep himself for a free dive. Truth be told, it would most likely help me during the daily grind and work schedule to release some stress and to literally "take a breather."And, while I wasn't able to experience freediving in the warm California waters off Santa Monica Pier, I was able to get my hands on the new Bremont?Supermarine Waterman during its quaint launch event at Shutters on the Beach.All images by John KimBremont's new Limited Edition Waterman extends the lineup of their already well received and distinctly designed dive watches with a few updates and is limited to 300 pieces. The Waterman is released in collaboration with Mark Healey, and will have a percentage of its sales proceeds contribut
