My answer is no. The reason is that we can never perform any measurement whose result is an irrational number. In this sense, **perfect geometrical entities, such as spheres, squares, circles, etc… do not exist in nature**.

## Are complex numbers found in nature?

**Nowhere**. They are a mathematical convenience – but in absolutely EVERY calculation, they magically cancel out and turn into real numbers when the calculation is completed and produces a “real world” answer.

## Are there irrational complex numbers?

By the way, the definition in that paper is convenient for use in that paper, but by the standard definition, **every complex number with non-zero imaginary part is irrational**. Irrational simply means not rational, and the rationals are a subset of the reals, so if it’s complex and not real it’s irrational.

## Why irrational numbers exist?

**They don’t seek to make things harder for themselves, they seek to make them easier**. Irrational numbers simplify. They fill in all the holes that exist in the set of rational numbers and make it possible to study limits, continuity, derivatives, integrals and so on. None of that is doable without irrational numbers.

## Who was the father of complex number?

The idea of a complex number as a point in the complex plane (above) was first described by Danish–Norwegian mathematician **Caspar Wessel** in 1799, although it had been anticipated as early as 1685 in Wallis’s A Treatise of Algebra.

## Are imaginary numbers real?

Numbers thought to have no analogue in the real world have meaning at quantum scales. Imaginary numbers have a real physical meaning, according to a new set of studies.

## Do irrational numbers exist in real life?

Irrational numbers exist in exactly the same way as Rational numbers, or Integers, or Natural numbers — as mathematical abstractions. **Whether that counts for you as existing “in real life” I can’t really say**, but if blue, love, or age exists “in real life” I don’t see why not.

## Are irrational numbers natural numbers?

Real numbers include natural numbers, whole numbers, integers, rational numbers, and irrational numbers. **Irrational numbers are those real numbers that cannot be represented in the form of a ratio**. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

## How did early mathematicians discover that irrational numbers exist?

Ancient Greece. The first proof of the existence of irrational numbers is usually attributed to **a Pythagorean (possibly Hippasus of Metapontum), who probably discovered them while identifying sides of the pentagram**.

## How complex numbers are used in real life?

Imaginary numbers, also called complex numbers, are used in real-life applications, such as **electricity, as well as quadratic equations**. In quadratic planes, imaginary numbers show up in equations that don’t touch the x axis. Imaginary numbers become particularly useful in advanced calculus.

## Are complex numbers rational?

Complex numbers are a separate set of numbers from the real numbers. Rational numbers are a subset of the set of real numbers. So **complex numbers are not rational**.

## Are imaginary numbers the 4th Dimension?

**The imaginary number with its imaginary axis acts as a fourth dimension**. The time substitution for the imaginary number is therefore valid. There is no dimensional inconsistency. The imaginary axis is at a right angle to the real axis for current, and the pythagorean theorem is used to calculate current.

## Why are there no 3D complex numbers?

There are no three dimensional numbers because **it’s impossible to construct such a system that behaves like ‘numbers’**. The real, complex, quaternion and octonion numbers are the only ‘normed division algebras’.

## Can time be a complex number?

This is an interesting question that can simply be answered as “**Yes, in general, time could be a complex number**”, however there are a number of nuances to be considered: In isolation, by itself, time is just vanilla.

## Is 3D a complex plane?

The complex plane is a **two dimensional real vector space** (using the natural identification (x,y)=x+iy).

## Is there anything beyond complex numbers?

Complex numbers include both real numbers, whose imaginary part is zero (such as pi and zero), and imaginary numbers, whose real part is zero (such as the square root of negative one). All numbers are of these types, so **there is nothing beyond complex numbers**.

## Is the complex plane real?

In mathematics, **the complex plane is the plane formed by the complex numbers**, with a Cartesian coordinate system such that the x-axis, called real axis, is formed by the real numbers, and the y-axis, called imaginary axis, is formed by the imaginary numbers.

## What is the argument of Z?

In mathematics (particularly in complex analysis), the argument of a complex number z, denoted arg(z), is **the angle between the positive real axis and the line joining the origin and z, represented as a point in the complex plane**, shown as. in Figure 1.

## How do i get ARGZ?

Arg z in obtained by **adding or subtracting integer multiples of 2π from arg z**. Writing a complex number in terms of polar coordinates r and θ: z = x + iy = r cosθ + ir sinθ = r(cosθ + i sinθ) = r eiθ . For any two complex numbers z1 and z2 arg(z1z2) = arg z1 + arg z2 and, forz2 = 0, arg (z1 z2 ) = arg z1 + arg z2.

## What is Argmin in math?

argmin(f(x)) simply **returns the value of x which minimizes f(x) over the set of candidates for x as opposed to the minimum value itself**.

## What is polar form?

The polar form of a complex number is **a different way to represent a complex number apart from rectangular form**. Usually, we represent the complex numbers, in the form of z = x+iy where ‘i’ the imaginary number. But in polar form, the complex numbers are represented as the combination of modulus and argument.

## What is mod Z?

Here, the modulus of z is **the square root of the sum of squares of real and imaginary parts of z**. It is denoted by |z|. The formula to calculate the modulus of z is given by: |z| = √(x^{2} + y^{2}) Modulus of z is also called the absolute value of z.

## What is R in complex numbers?

In the case of a complex number, r **represents the absolute value or modulus** and the angle θ is called the argument of the complex number.
