Learn about the mathematical concept of four-dimensional space (4D), its history, geometry, and applications in physics and mathematics. Explore the visualization methods, examples, and analogies of 4D objects and phenomena.
14 Απρ 2023 · Learn how to visualize the fourth dimension by extruding a cube in a direction perpendicular to the third dimension. Explore the properties and implications of tesseracts, the 4D analogues of cubes, and how they differ from our 3D world.
30 Ιαν 2023 · In a new video, a physicist reveals what the fourth dimension looks like—and where it may be.
Thinking of the Universe as four-dimensional ‘space-time’ proved incredibly powerful, and led to a host of insights about how the Universe and the forces at work in it. For example, according to Einstein, gravity is best understood as being the result of the warping of space-time by matter.
15 Ιουν 2022 · Time is a universal whose nature we all fail to grasp. It is a physical, dynamic thing, fused with space to form space-time, but it also has a block-universe view and a quantum structure that challenges our intuitions.
26 Απρ 2017 · Learn how to create and project a 4D hypercube, a 4-dimensional analogue of a cube, using stereographic projection. Explore the mathematical and physical implications of higher-dimensional space and time with examples and resources.
1 Φεβ 2017 · How do physicists explain the nature of time and its relation to space? This article explores five different approaches, from quantum mechanics to entropy, from illusions to asymmetry, from snapshots to equality.
