# What is the problem of Einstein?

## 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?

Einstein actually had friends take notes for him in class while he was out reading about physics and math.

How did Einstein take notes?

### What was Einstein famous for?

### Did Albert Einstein fail math?

1. Einstein didn’t fail math as a child. When later presented with a news article claiming he’d failed grade-school math, Einstein dismissed the story as a myth and said, “Before I was 15 I had mastered differential and integral calculus.”

How many hours does Einstein sleep?

What is an irrational number?

An Irrational Number is a real number that cannot be written as a simple fraction. Irrational means not Rational Let’s look at what makes a number rational or irrational…

### When did irrationality first appear in mathematics?

It is suggested that the concept of irrationality was implicitly accepted by Indian mathematicians since the 7th century BC, when Manava (c. 750 – 690 BC) believed that the square roots of numbers such as 2 and 61 could not be exactly determined.

### 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.
