Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
Having four dimensions, typically the three dimensions of space (length, breadth, and depth) plus time.
- ‘One could imagine that, as a consequence of the dynamics, the extra six dimensions form a small compact space attached to each point in ordinary four-dimensional space-time.’
- ‘It's also possible to picture each card as a point in four-dimensional space, where each of a point's four coordinates assumes one of three possible values.’
- ‘The theory that Paul described in particular involves a four-dimensional space plus one time dimension, which he called the bulk.’
- ‘What exactly this means is hard to imagine, rather like trying to picture a four-dimensional cube.’
- ‘But the ultimate theory of gravity should explain why the universe is four-dimensional and how those dimensions arose, say researchers trying to unify the theories of quantum mechanics and relativity.’
- ‘For the extreme pathway matrix of this system, there are four singular values, indicating a four-dimensional cone residing in the nine-dimensional flux space.’
- ‘I like to know my place in four-dimensional space.’
- ‘They again use an extra dimension of space, imagining that our world is a three-dimensional ‘brane’ embedded in a four-dimensional space (plus one time dimension, as usual).’
- ‘In 1908, one of Einstein's mathematics lecturers, Hermann Minkowski, presented relativity theory in geometric form - in the four-dimensional geometry of space and time.’
- ‘Mathematicians also study what they call the three-dimensional sphere - the set of all points a given distance from a center in four-dimensional space.’
- ‘In classical relativity theory, space-time is a four-dimensional construction wherein the three dimensions of space and one dimension of time are welded together.’
- ‘Unlike ordinary three-dimensional objects, these shapes live in four-dimensional - or higher - space and curve in on themselves as the sphere and torus do in three-dimensional space.’
- ‘To discover significant elements in any given sociocultural system of body language, we need to start with the physical and logical possibilities and impossibilities of the human body in four-dimensional space.’
- ‘In the Theory of Relativity, time is no more an independent physical quantity - it is linked with space in four-dimensional space-time.’
- ‘Still later, in Los Angeles, he lectured as a ‘World-Famous Mystic’ on prophecy, vision, cosmic consciousness, and four-dimensional space.’
- ‘The full four-dimensional space, or five-dimensional spacetime, is referred to as the bulk.’
- ‘Is time just a fourth dimension which, together with the three dimensions of space, helps to comprise a unitary four-dimensional manifold in which all physical objects and events somehow reside?’
- ‘The real laws and their unchanging constants would exist in the four-dimensional space, and our three-dimensional section of it would not necessarily have unchanging constants associated with it.’
- ‘Thus, the entire geometry of a manifold can be formulated in terms of an atlas, so that it is not necessary to think of the manifold as really being a three dimensional surface lying in a four-dimensional space.’
- ‘Fortunately, in living systems certain conditions must be fulfilled for three-dimensional bodies to occur in four-dimensional space.’
