Tell me something I don’t know.
This is not a sarcastic post.
There are lots of things I don’t know.
So, tell me something you know for a fact that you think I might not know.
I am on a learning spree. 
I already discovered one thing I didn’t know.
That the thread title appears in the body of the thread without me having to re-type it. :smack:
Next, please.
This reminds me of my days in “A” school in the Navy - just before we’d walk into class to take a test, one guy would go around asking everyone to tell him one fact about the material we were about to be tested on. Invariably, I’d hear something that I’d forgotten and it would show up on the test, and I’d get points I’d otherwise have missed.
Not that you just learned anything from that. OK, a fact: Female blue crabs mate only once in their lives, when they become sexually mature immediately following their pubertal molt (immediately following this molt, the female is known as a “sook.”) (from here.)
Almonds and pistachios are the only nuts mentioned in the Bible. 
Interesting.
Makes me feel thankful that I am not a female blue crab. 
I wonder where the word “sook” comes from.
The rhyme “On old Olympus terrace tops a Fin and German vaulted a hedge.” is a mnemonic for the 12 cranial nerves: Olfactory, Optic, Ocular-motor, Trochlear, Trigeminal, Abducens, Facial, Auditory, Vagus, Accessory, and Hypoglossal.
Are they the “religious nuts” I have heard being referred to?
No cashew nuts? 
No wonder there are so many atheists.
Given a particle’s position, you cannot know it’s velocity. Of course, if you know it’s velocity then you cannot know it’s position.
What I’m trying to say is that it’s hard to know what you don’t know if I don’t know what you don’t know. Or something like that.
Tapered pipe threads are angled 1º, 47’.
Isn’t that the Heisenberg “Uncertainty Principle”?
Ooooo, thank you!
Two things I don’t know in one sentence.
Never heard the rhyme and did not know it was a mnemonic for the 12 cranial nerves.
Definitely something I did not know.
And I still don’t know what it is useful for.
-The capital of Madagascar is Antananarivo
-Columbos didn´t sail the sea and stumble upon America in three caravels, it was two caravels and a nao (Santa Maria)
-The longest muscle of the human body is the Sartorium. Goes from the hip to the knee turning around the leg.
-My grandmother´s (from my father´s side) middle name was Otilia… well, I´m sure you didn´t know that!
The longer the playing time on an LP, the noisier the record is, and the less bass frequencies it contains. This is because they have to cut the master at a lower volume, so the grooves don’t modulate from side to side as much, and so, take up less space, to accomodate the longer playing time. And they have to reduce the bass so your stylus doesn’t jump out of the shallower grooves. This causes noises and clicks to sound more prominent, where they might otherwise be covered up by louder music on a shorter record.
Yaks give pink milk.
The letter “C” in Latin is pronounced as a “K” sound, and “V” is pronounced as “W”. Think about it next time you think of Cicero or Ovid.
Gandhi was buried in California.
I have exactly $3.85 in my pocket.
Bet you didn’t know that man has visited the deepest part of the ocean just once in 1960, for 20 minutes.
If you have an amplifier driving a set of speakers with say, 100 Watts, to get a slight increase in volume (i.e. when you “turn it up a notch”, or +3 dB) requires doubling the power, or 200 W. If you wanted to increase the volume to twice as loud, you would need ten times the amount of power, or 1000 W!
And tailor’s would sit cross-legged while they did their work, stressing this muscle. Another name for the muscle is the tailor’s muscle. It gives us words like sartorial. And that’s the rest of the story.
Only one British Field Marshal rose from the enlisted ranks: this one.
