## What is the problem of Einstein?

In plane geometry, the einstein problem asks about the existence of a single prototile that by itself forms an aperiodic set of prototiles, that is, a shape that can tessellate space, but only in a nonperiodic way.

## Did Albert Einstein take notes?

### What was Einstein famous for?

**What is an irrational number?**

### When did irrationality first appear in mathematics?

### How to tell if a decimal expansion is rational or irrational?

In the case of irrational numbers, the decimal expansion does not terminate, nor end with a repeating sequence. For example, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat. Conversely, a decimal expansion that terminates or repeats must be a rational number.

**Is 3 14 a rational or irrational number?**

Ans: The number 3.14 is a rational number as the given number can be written in the form of a fraction or it has a terminating decimal. Q.2. Is 5 an irrational number? Ans: The number 5 is not an irrational number as it can be expressed as the quotient of two integers: 5 = 5 1.
