"Science is fun. Science is curiosity. We all have natural curiosity. Science is a process of investigating. It's posing questions and coming up with a method. It's delving in."
-- Sally Ride
If scientists from the future were to be asked about the significant discoveries of the 2010s, the term 'time crystal' would probably be at the top of that list.
Time crystals are solid compounds in which some atoms have been observed to "tick" regularly when exposed to electromagnetic fields.
The definition may sound a little underwhelming. However, it is the first example of atoms behaving in this manner.
In addition, time crystals may have many important roles in the electronics and engineering of the future.
