When we look at an object from a certain direction, what we see is called a view of the object.

Also called probability, it’s a core concept in math used to measure and describe how likely random events are to happen.
Probability is a branch of mathematics used to study the rules and possible outcomes behind random events. In real life, we often run into situations where we need to predict results, and probability theory was created to solve these kinds of problems.
A real solution, simply put, is when the result of an equation is a real number, meaning it's a number we can find on the number line, not an imaginary number.
Real numbers are the most basic set of numbers in math, including all rational and irrational numbers. Simply put, they are the numbers that can fill up the entire number line.
In math, spacetime is defined as a four-dimensional continuous manifold. It's a geometric structure that combines three-dimensional space with one-dimensional time. The main math tools for it include the Minkowski metric (for special relativity) and Riemannian geometry tensors (for general relativity).
The concept of time includes moments and periods. Time is a parameter humans use to describe the process of material movement or the occurrence of events.
An hour is the internationally used unit of time, and 1 hour equals 60 minutes or 3600 seconds.
A hendecagon is a flat shape with 11 sides and 11 angles, and it’s a type of polygon.
A pentadecagon is a flat polygon with 15 sides and 15 angles, and the sum of its interior angles is fixed at 2340 degrees.
