In its simplest form, the equation of time is defined as the difference between the time displayed by the position of the sun (as by a sundial) and the time displayed by any modern clock or watch. But that’s just the beginning, and watchmaker Ashton Tracy explains more.
Given Panerai’s origins in Florence, it should come as no surprise that the Italian watchmaker created a horological tribute to the insatiably curious father of modern science Galileo Galilei, who was once a resident of the Renaissance city. The Jupiterium is a one-of-a-kind geocentric planetarium with perpetual calendar.
In the Real Moon Tides, Christiaan van der Klaauw’s watchmakers incorporated an indication of the phenomenon that is the most real-world expression of the moon’s effects towards life on earth: tides. The most incredible aspect of tides is how variable they actually are when you really get into the nitty-gritty details. And this watch reflects them in a beautiful way.
While we see Polaris as the North Star for now, our descendents twenty generations down the road from now will not. This is due to an astronomical process called precession. There is something that mimics precession that you can wear on your wrist and pass on to those descendents: the Jaeger-LeCoultre Duomètre Sphérotourbillon Moon, the most recent addition to Jaeger-LeCoultre’s already stacked Duomètre collection.
It’s a story that could have come out of a thriller novel, and it’s about the oldest known watch in the world, which was made in 1505 by Peter Henlein. The Pomander Watch (‘Bisamapfeluhr’), as it is known, was confirmed by committee of experts as having been the work of Peter Henlein in 1505.
How much time one could survive in space without a suit, whether there are truly 24 hours in a day, why dinosaurs cannot live in the present day (shock: ‘Jurassic Park’ is complete fiction), where most of the volcanos are, if there is a river beneath the Amazon, how long since it has rained on the driest place on earth, and what percent of the world’s species we have discovered (hint: not many), and much more more.
Here are 50 things you should know about the planet we live on.
The peacock’s iridescent colors are not actually pigment colors at all, but are reflections off the structure of the feathers, which have patterned nano-fiber components. Slight changes in the spacing of the nano-fibers produce different colors much in the same way as iridescent colors reflect off a film off brown/black oil or a butterfly’s wing. But they are none less beautiful for that.
This article I focuses on Selective Laser Sintering (SLS), which utilizes a high-powered laser to heat a powdered material and sinter it into a solid structure. This is the process most likely to change the watchmaking industry, as it is able to print with metals and ceramics.
I went to the theater recently and saw a typical raunchy comedy called ‘Neighbors.’ Much to my surprise, I saw something I cannot remember ever seeing in a mass-marketed movie: a 3D scanner and 3D printer being used by the main characters in a funny circumstance. (For said circumstance, please watch the movie because it cannot be discussed here.)
Contemplating the 30-meter-high ancient pyramid at Mayan archeological site Chichén Itzá in the blazing Yucatán sunlight, I was awestruck by the structure’s complexity. Not just because of the pure historical ramifications of the pyramid and temple , but also because of its timekeeping capabilities. Chichén Itzá’s most famous structure was actually built to be the world’s largest calendar And this at a time when calendars didn’t even exist!
