Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the euclidean dimensions?Three spatial dimensions (length, width, height) forming a 3D space
2. What is the spacetime coordinates?Four coordinates (x, y, z, t) used in Einstein's theory of relativity
3. What are the three dimensions we see in everyday life?We see length, width, and height. These are the three directions that let us measure where things are and how big they are. We can use coordinates x, y, and z to describe any point in this space.
4. Why does Einstein add time as a fourth dimension?Einstein showed that time is not the same for everyone; it changes depending on how fast someone moves. By adding time as a fourth dimension, we can describe events in a single, four‑dimensional space called spacetime.

Manifold: A topological space that locally resembles Euclidean space, used to describe spacetime.
Compactification: The process of 'curling up' extra spatial dimensions to a very small size.
Vector Space: A mathematical structure where vectors can be added and scaled, defined by its dimension.
