The world is full of strange, amazing, terrifying, weird, interesting things. I like random facts, and I think it's fun to share them. There are also things it's just cool to know. So this is my world of expanding knowledge.

If you, too, like random facts and have some to share, you can always ask to be a guest poster.

And if you want more random facts, I'm on Tumblr more often than here and tag related posts with "now you know". Check that tag out here.

What the hell are "cockles"

So I was on Tumblr and I read the phrase, "warms the cockles of the heart" followed by someone asking, "What the hell are cockles, anyway?" So I googled it and this is what I found.

Something that "warms the cockles of the heart" or "warms the cockles" for short elicits pleasure or affection. So what are cockles? The expression began in the middle of the seventeenth century in a slightly different form that went something like "rejoice the cockles of the heart".
"Cockles are a kind of bivalve mollusc, once a staple part of the diet for many British people (you may recall that Sweet Molly Malone once wheeled her wheelbarrow through Dublin’s fair city, crying “cockles and mussels, alive, alive oh!”). They are frequently heart-shaped (their formal zoological genus was at one time Cardium, of the heart), with ribbed shells."
It's speculated that that the shape and the spiral ribbing of heart ventricles reminded surgeons of cockles, but the source was not entirely sure that this explanation was correct.
There is another possible explanation. In medieval Latin, heart ventricles of the heart were called cochleae cordis, where the second word is an inflected form of cor, heart. In Latin, Cochlea means 'snail' "(from the shape of the ventricles — it’s also the name given to the spiral cavity of the inner ear), so if this story is right we should really be speaking of warming the snails of one’s heart".

My own note to add to this: I now know why Cochlear implants are so named.

Cockles is still a weird word.

Blue whale

So I'm not sure if this is true or not.

Google says its true but the one Youtube video showed a bunch of small bubbles, which I find much more believable. Okay, so I actually searched this. I'm immature and bored, so sue me.

The quietest place

It's been a while since I posted here. I have to start finding more facts for you guys. I hope that people actually start checking these out, because...I don't know...because it's cool to know this stuff.

According to some myths, birthmarks are where you were killed in a past life. Interesting theory...
