Today’s generation is so much better informed than I was as a kid. With science and mathematics developing new ideas and techniques, children are learning more information at a younger age. The ability to explain something in a lecture style takes not only confidence but a sure understanding of the subject matter. This High School student definitely has both. The difference in spatial dimensions can be hard to wrap your head around so seeing a kid thinking so clearly is very neat. If you don’t know much about the difference in dimensions this is a great place to start. The young man is clear and concise.

This students explains the difference in dimensions starting at one dimension, working his way to the fourth. For reference, we are exist the third dimension. He explains very accurately how a viewer in each dimension has a profoundly different view of the visible universe. In the first dimension there is no height, only width and length. Movement by any potential inhabitant would be limited to movement along this one plane. The second dimension has height added to it but no depth. Beings in the second dimension could view and interact with the first dimension but one dimensional beings would have a hard time interacting back.

He explains how time is not the fourth dimension. The fourth dimension is a categorization of space and time is a separate element. The sad part is how we can’t imagine anything beyond our dimension. Theoretically there are infinite dimensions and all of them are curved. Gravity will always be present when there is mass. This force will cause warps in what is visible and what is not.
