This famous painting by Caspar David Friederic is entitled Wanderer above the Sea of Fog. To me it's a kind of commentary on the human condition, but also a perspective on what may have inspired Newton, Einstein, and so many others.

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.”

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.

Q. What would you call rice arranged in a column? 

A. Pillar rice. 

I find ironing clothes so tedious nowadays. I guess I’m just ironing bored.

“I forbid you to go to the dance contest”, said Tom strictly.

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

E was just an ordinary vowel really. Much like U and I.

My vacuum cleaner should suck.

It doesn’t suck.

Therefore, it sucks.
