What is the 3rd dimension? - Relativity - Science Forums
2020年10月14日 · The third dimension is equally pictured as height, depth, and thickness, and lends a quality to objects we think of as solid. Time (t) is a temporal dimension in a continuum with the spatial dimensions (spacetime).
What is the 5th Dimension exactly? - Science Forums
2013年9月23日 · The second dimension has two axes, the [math]x[/math]-axis and the [math]y-axis[/math] forming the [math]xy[/math] plane. Likewise, the third dimension has three axes forming an "xyz space" (very informal wording). When we go beyond the 3rd spatial dimension, things get hard to visualize, but conceptually it all follows the same basic principle.
euclidian geometry vs. Cartesean coordinates - Science Forums
2005年12月31日 · So you have inspired me to get a copy of Euclid's Elements, thank you for that. But I still do not see what Descartes added to Euclid's spatial models of X and Y coordinates, and in turn as I understand it a third dimension Z. Was it simply the algebra that defined the nature of lines, curves and shapes within this three dimensional space?
New! 3D Mnemonic diagram for filling orbitals. - Science Forums
2008年6月30日 · I'd like to share with you new, three dimensional diagram, where the third dimension shows magnetic quantum number "ml", in addition to "n" and "l": 3D Mnemonic Diagram. 3D diagram illustrates well how all three quantum numbers are interconnected in a single geometric construction known in mathematics as the tetrahedral close sphere packing.
Can you make a concept of the 5th dimension?
2011年8月21日 · If you were a Flatlander, the fourth dimension (height) would be ordinarily invisible, except as it leaves a footprint in Flatland. Flatlanders would know time, so the fourth dimension for them is height. Now take this a step further with existence in 3-D spacetime. The extra dimension would only be evident by its footprint in 3-D spacetime.
Kip Thorne's take on Gravity - Relativity - Science Forums
2017年3月29日 · Consider a 2D representation of 3D space, and stack these sheets, or foliations, on top of each other in the third dimension ( as time advances ). If time is advancing at different rates in different areas of these 2D foliations, we notice a 'depression' in the stack of foliations where time is advancing slower.
Non-unifying Geometrized Newton-Cartan Gravity
2018年4月6日 · A third dimension has time dilated to a stand still, but this fractal counterpart has time contracted as a dynamicalized version of that static temporal state. Time in this theory isn’t being thought of as a third dimension moving through the 4th dimension .
4th dimension and light - Speculations - Science Forums
2011年8月26日 · When massed together the combined reduction in the fourth dimension combines to attract other atoms which combine to form molecules and so on. It is the combination of all these fourth dimension reductions that is responsible for gravity. The fourth dimension theory poses some questions about the way atoms and subatomic particles react.

2005年5月18日 · Could a two dimensional universe even exist without the third dimension to relate the first two (after all, how could two infinately thin pieces of matter be beside each other)? Even pencil drawings have graphite in them. Where do you stand on two dimensional life? Four, above? Is three dimensions the be all and end all for the existance of life?
How do planets orbit in the same plane if the orbital space is …
2021年12月4日 · The second image is an analogy which visualizes space as being 2 dimensional and bent through a third dimension. It is not representative of reality. In it all of space is the surface shown as a grid. And while the diagram shows the Sun and planets as solid objects sitting on that grid, they would better be represented as circles on the surface.
