The constipated mathematician...

My brother has a degree in engineering. Stacks of books and years of study. He tutored his oldest son in calculus and remembers how to use a slide ruler. He's designer and built bridges... even wrote a book on the subject.
One of his college buddies often talked about the story of the constipated mathematician.
They say he worked out with a pencil!

While on the topic of pencils, I found a really interesting video on the making of Faber-Castell pencils. The video claims they produce 2.3 billion pencils a year.

I think we've had a thread before on the invention making and cost of Astronaut pencils, have we not?
Ah, it is a pen in fact. Lead shavings are not welcome in space amongst electonic equipment.

The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
I would have guessed, that it would have been even more automated by now.
It seems there is still a lot of hands on transfers.

Damn ! I haven't seen a pre-sharpened pencil in a long time.
That's a nice touch.

People and not machines. I'm okay with that.
It's not broken, no need to fix it.
Those who are employed by Faber-Castell can surely appreciate that concept.
I'm not objecting to it. I'm just a bit surprised.
