<p>When you put a cube of ice ...

When you put a cube of ice in glass of water, you’re introducing two separate entities (the ice cube and the liquid water) to each other at two different temperatures.

Everyone knows that the water will get colder (that’s why we put the ice in there) and, over time, the ice will get warmer and turn into water. Eventually you’ll just have a glass of room-temperature water.

We call this process “thermal equilibrium .”

Most people are familiar with Newton’s first law of motion , it’s the one that says “an object at rest tends to stay at rest and an object in motion tends to stay in motion.”

MORE IDEAS FROM Google may have achieved a scientific breakthrough: Time crystals

Time Crystals

Eureka! A research team featuring dozens of scientists working in partnership with Google‘s quantum computing labs may have created the world’s first time crystal inside a quantum computer.

These scientists may have produced an entirely new phase of matter. I’m going to do my best to explain what that means and why I personally believe this is the most important scientific breakthrough in our lifetimes.

According to classical physics, the universe is always moving towards entropy . In other words: if we isolate an ice cube and a room-temperature glass of water from all other external forces, the water will always melt the ice cube.

The entropy (the movement towards change) of any system will always remain the same if there are no processes, and it will always increase if there are processes.

Since our universe has stars exploding, black holes sucking, and people lighting things on fire – chemical processes – entropy is always increasing.

Life Lessons from the Rubik’s Cube
  1. It is easier to create chaos than to create order. We prefer order, but creating it takes effort.
  2. Approaching order sometimes involves creating more chaos. Steps backward are often necessarily to move forward with integrity.
  3. You cannot resolve chaos all at once. Pick your battles. You cannot solve everything at once.
  4. Chaos is easier because there are more ways to be chaotic.
  5. To the uninitiated, systematic applications of complex patterns look like magic.

Absolute time does not exist

Time moves slower the closer you are to Earth. In his theory of general relativity, Einstein explained that the gravity of a large mass, like Earth, distorts the space and time around it.

In 2010, researchers placed two precise atomic clocks, one 33 centimetres higher than the other. Time moved slower for the clock closer to Earth. This confirmed that absolute time does not exist.
