## What is N-body calculation?

In physics and astronomy, an N-body simulation is a simulation of a dynamical system of particles, usually under the influence of physical forces, such as gravity (see n-body problem).

## What are N-body simulations used for?

Gravitational N-body simulations, that is numerical solutions of the equations of motions for N particles interacting gravitationally, are widely used tools in astrophysics, with applications from few body or solar system like systems all the way up to galactic and cosmological scales.

**Can you solve the three body problem?**

No general solution of this problem (or the more general problem involving more than three bodies) is possible, as the motion of the bodies quickly becomes chaotic.

### Is the 3 body problem solvable?

The inclusion of solar perturbations of the motion of the Moon results in a “three-body problem” (Earth-Moon-Sun), which is the simplest complication of the completely solvable two-body problem discussed above.

### Is 3 body problem unsolvable?

As a lot of scientists try to solve three body problem and are wasting their time. It is believed to be unsolvable, yet commonly observed in the universe.

**Can we solve the 3 body problem?**

There is no general closed-form solution to the three-body problem, meaning there is no general solution that can be expressed in terms of a finite number of standard mathematical operations. Moreover, the motion of three bodies is generally non-repeating, except in special cases.

#### Why is the 3 body problem so hard?

The fundamental problem is to predict the motions of three bodies (such as stars or planets) mutually attracted by gravity, given their initial positions and velocities. It turns out that a general solution to the problem is essentially impossible due to chaotic dynamics, which Henri Poincaré discovered in 1890.

#### What do you need to know about body physics?

Body Physics sticks to the basic functioning of the human body, from motion to metabolism, as a common theme through which fundamental physics topics are introduced.

**What’s the real name of N from VIXX?**

N real name is “Cha Hak-yeon” (Hangul: 차학연). He was born on June 30, 1990 in South Gyeongsang Province, South Korea. He has an older brother and two older sisters.

## Who is in charge of visuals in VIXX?

Hongbin is the member in charge of visuals, and it’s not for just any reason. Boasting an incredible, naturally well-structured face, gorgeous skin, and a rocking body, he has been lighting up the stage and TV since the beginning of VIXX. Hongbin is incredibly active within the drama community.

## Who is the lead singer of the band VIXX?

“N” (Hangul: 엔) is the Leader, Lead Vocalist and Main Dancer in VIXX. He debuted with VIXX on May 25, 2012 with their 1st single album ” SUPER HERO “. He debuted as an actor in the drama “Hotel King” as Noah in 2014. He debuted as a musical actor in the musical “In The Heights” as Benny in 2016.
