Surprisingly, the name of this bird seems to come, ultimately, via Anglo-Norman and Latin, from Ancient Greek πέρδεσθαι, perthesthai, to break wind. It’s believed to be imitative of the rapid whirring of a partridge’s wings as it takes off from the ground (if you have ever heard this sound you’ll recognise the resemblance). The word fart comes from the same root.
I found this quote today
“The important thing is not to stop questioning. Curiosity has its own reason for existence. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery each day.”
When icicles hang by the wall,
And Dick the shepherd blows his nail,
And Tom bears logs into the hall,
And milk comes frozen home in pail.

It seems counterintuitive that you can make a hole through a cube that will let a bigger cube pass through it. But you can.
The probem is named for Prince Rupert of Palantine (1619-1682), although he seems to have only asked about cubes of equal size. However it turns out that if the first cube has sides 1 unit long, a second cube of side just over 1.06 units can pass throught it.
The sketch below gives an indication of how this can be done.
A, B, C and D are each 1/4 the way along an edge and using Pythagoras we find AB = BC = CD = DA which is just over 1.06. If we bore a hole perpenidicular to square ABCD with ABCD as cross-section then a cube of edge 1.06 can pass through the hole in the cube of edge 1.
Interestingly the distances AB, BC, CD, and DA are also equal if we measure them along the edges of the cube. 3/4 + 3/4 = 1/4 + 1 + 1/4.
Even more amazingly other solids such as a tetrahedron have the same property. For example it's possible to pass a tetrahedron through a hole in a smaller tetrahedron.
In Philosophy you’ve got to tread carefully. It’s a mind field.

It seems the underworld have an award for the most successful attempt to influence a jury. It’s known as the nobble prize.

Not many people know this but the US has a heavily-guarded facility where enormous quantities of string are stored. It’s called Fort Knots.

I wrote a program to search for words that contain only the letters abcdefg used as musical notes. I found 124 in the wordlist CROSSWD.TXT (courtesy of Moby Words II by Grady Ward). A bigger wordlist might find more. The 124 words appear below. What's the longest meaningful sentence you can find using only these words? If we can use proper names like 'Abe' we could have
Aged Abe deeded a faded cabbage bed.
Q. What do call a race between sea snails? A. The limpet games.
Until yesterday I had no idea that you can freeze soap bubbles. But you can.
