![]() ![]() ![]() A position in spacetime is called an event, and requires four numbers to be specified: the three-dimensional location in space, plus the position in time (Fig. 1). In the Cartesian coordinate system, these are called x, y, and z. In ordinary space, a position is specified by three numbers, known as dimensions. : 214–217 General relativity also provides an explanation of how gravitational fields can slow the passage of time for an object as seen by an observer outside the field. In the context of special relativity, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer. Furthermore, it assumes that space is Euclidean: it assumes that space follows the geometry of common sense. Classical mechanics assumes that time has a constant rate of passage, independent of the observer's state of motion, or anything external. Non-relativistic classical mechanics treats time as a universal quantity of measurement which is uniform throughout space, and separate from space. This interpretation proved vital to the general theory of relativity, wherein spacetime is curved by mass and energy. In 1908, Hermann Minkowski presented a geometric interpretation of special relativity that fused time and the three spatial dimensions of space into a single four-dimensional continuum now known as Minkowski space. However, space and time took on new meanings with the Lorentz transformation and special theory of relativity. ![]() Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe (its description in terms of locations, shapes, distances, and directions) was distinct from time (the measurement of when events occur within the universe). Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur. ![]() Uttermost’s complete product line includes mirrors, art, alternative wall décor, accessories, lamps, botanicals, lighting fixtures, and accent furniture.In physics, spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. The Timeworks product line will be shown in Atlanta, Dallas, Las Vegas, and New York this month in the Uttermost showrooms. It’s a wonderful and natural fit and we look forward to helping Uttermost build the brand in the months and years ahead."Ĭo-founder Steve Kowalski had similar thoughts "As a product designer, I am thrilled about continuing to develop distinctive Timeworks clocks for Uttermost, knowing that their greater resources will allow me to expand the possibilities for creativity, and that Timeworks will maintain and expand it's reputation and standing as America's number one clock brand". Timeworks co-founder John Kowalski, added "we are so proud that the Timeworks name and product development will continue and the brand could not have found a better home than Uttermost. "The founders of Timeworks will be leading the way in product design and development of Timeworks, so this line will grow substantially from where it is today" according to Cooper. Per Mac Cooper, CEO, "I’ve been a fan of Timeworks for many years, and could not be more excited to offer this product to our customers." Uttermost is continuing almost the entire Timeworks assortment from 2010, along with new Timeworks introductions at the January markets. Uttermost has acquired the Timeworks brand name, product designs, etc, and now is available exclusively through Uttermost. Timeworks, Inc, a Berkeley California company and industry leader of innovative clocks, is now an Uttermost brand. ![]()
