It’s weird to think that we perceive two equal curves meeting at a point at the bottom and a cusp at the top, or the combination of the less than sign and number three, like a heart.
Sure, it’s a symbol, the origins of which are nested back in the 6–5th century BC, that we all now assume as being the heart, though an actual human heart looks nothing like it.
But, regardless, it’s a cute symbol that we immediately recognize anywhere as the symbol of love. Well, turns out, nature approves of this symbol, as seen in this amethyst geode that some miners recently found.
This may be an arbitrary shape of a heart that we humans came up with, but turns out nature uses it too
