# Signs of Science

Signs of Science is an evolving collection of illustrations, each inspired by one of the foundamental and famous scientific principles and formulas that defines our knowledge in physics and mathematics.

Each minimal infographic illustrates and tries to give a visual explanation of the scientific principle.

## Newton’s Laws Infographics

Newton’s First Law
The first law of motion states that if the net force (the vector sum of all forces acting on an object) is zero, then the velocity of the object is constant.

Here circles are the bodies that move through time following the straight lines of constant velocity.

## Newton’s Second Law

Newton’s Second Law
The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.

The curved lines show inverse proportionality between mass (x axis) and acceleration (y axis) for a given force.
In the animation, force varies, making the lines move.

## Newton’s Third Law

Newton’s Third Law
Newton’s third law states that to every action, there is an equal and opposite reaction.

Newton’s pendulum is a very good example that portrays this principle.

# Laws of Thermodynamics

## Zeroth Law of Thermodynamics

Zeroth Law of Thermodynamics

“If two assemblies are each in thermal equilibrium with a third assembly, they are in thermal equilibrium with each other.” – 1871, James Maxwell; 1939 Ralph Fowler.

Here the three square systems reach reciprocal thermal equilibrium. Thanks to Zé Nuno for the scientific support.

## First Law of Thermodynamics

First Law of Thermodynamics

“The increase in the internal energy of a system is equal to the amount of energy added to the system, minus the work done by the system.” – 1850, Rudolf Clausius

In the animated infographic, the triangle represents the isolated system. The line Q is the energy added to the system, which causes the internal energy to vary.

## Second Law of Thermodynamics

Second Law of Thermodynamics

“In an isolated system, entropy can increase only” – 1850, Rudolf Clausius .

In this animated illustration the circle is an isolated system, and it contains the lines of increasing entropy.

## Third Law of Thermodynamics

Third Law of Thermodynamics
The Third Law of Thermodynamics states that as a system approaches absolute zero, all processes cease and the entropy of the system approaches a minimum value.

I’ve visualized this scientific principle showing the varying intensity of the motion of the atoms when the temperature changes.
The animation is generative and coded with Processing.
