Learn about the mathematical extension of three-dimensional space to four dimensions, and how it is used in physics, geometry, and art. Explore the history, properties, and examples of four-dimensional objects, such as the tesseract and the Minkowski space.
14 Απρ 2023 · Learn how to visualize and imagine the fourth dimension by extruding a cube in a direction perpendicular to the third dimension. Explore the properties and characteristics of tesseracts, the 4D analogues of cubes, and how they differ from our 3D world.
11 Νοε 2023 · Learn how Einstein's theory of relativity rejects the concepts of space and time as separate dimensions and unifies them into spacetime. Discover how mass and energy bend spacetime and create gravity, and how spacetime itself is a dynamic actor in the universe.
Why do scientists believe that our universe consists of more than three dimensions? And how can we even begin to conceptualize this? In this video, Michio Ka...
The 4th dimension can be an extremely confusing topic. In many ways it’s impossible to understand, but through simple analogies and explanations, it can be come one of the most fascinating topics you’ll learn about all year.
We’re familiar with three dimensions, where just three numbers are enough to pin down our location: longitude, latitude and altitude. We’re also surrounded by three-dimensional objects that we describe using length, breadth and height. For thousands of years, the existence of a fourth dimension was dismissed as ridiculous.
3 Απρ 2014 · Learn how physicists use mathematics and theory to explore the possibility of extra dimensions beyond the four of spacetime. Discover the evidence for three dimensions from gravity, the evidence for four dimensions from relativity, and the proposals for more dimensions from string theory and brane worlds.
