When a thick lava flow cools it contracts vertically but cracks perpendicular to its directional flow with remarkable geometric regularity – in most cases forming a regular grid of remarkable hexagonal extrusions that almost appear to be made by man. One of the most famous such examples is the Giant’s Causeway on the coast of Ireland (shown above) though the largest and most widely recognized would be Devil’s Tower in Wyoming. Basalt also forms different but equally fascinating ways when eruptions are exposed to air or water.
KNOWLEDGE Knowledge is a familiarity with someone or something, which can include information, facts, descriptions, and/or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic.In philosophy, the study of knowledge is called epistemology, and the philosopher Plato famously defined knowledge as "justified true belief."
