AS KIDS, YOU probably learned that matter — the stuff that makes up us and everything else — can come in three different states: solid, liquid, and gas.
In high school or college, more exotic forms of matter may have been added to the list like Bose-Einstein condensates and plasma, which form at very low and very high energies respectively. Like your eighth-grade science class that was mesmerized watching an ice cube sublimate into a swirling steam, many scientists have turned their professional curiosity to the study of matter states as well.
