I bought a couple of 10mm cubes, one of Nickel, one of Cobalt, because I read that cobalt and nickel are ferromagnetic, strongly attracted to magnets. I could not distinguish the two cubes based on density. I’m documenting my effort to distinguish them based on magnetic attraction.
My son, Everett, helped me with experiment design and execution.
I’ve got what Amazon sells as Sunnytech Mini Hot Live Steam Engine Model Education Toy DIY (BJ001)
Some very simple assembly is required.
Is tungsten carbide magnetic?
You can’t use the World Wide Web to find a definitive answer!
It turns out you can buy little cubes of various elements from sketchy Amazon marketplace vendors.
Naturally, I wanted some Tungsten, because of its incredible density.
Long about 1996, I read The Text of the New Testament (subtitled Its Transmission, Corruption and Restoration) by Bruce M. Metzger, 3rd edition.
Optimal Smurfing in English and Greek Catherine Chatzopoulos, 2008, University of Chicago, Aristotle University of Thessaloniki
I found a PDF version of the paper.
I read an interesting paper:
A Smurf-based Approach to Placeholder Expressions, July 2021, by Manfred Sailer and Annika Dörner
which apparently appeared in:
Proceedings of the 27th International Conference on Head-Driven Phrase Structure Grammar, Online (Berlin/Seattle), 2020.
This summer, we rode the 1880 Train, from Keystone SD to Hill City SD, and back. Easily worth the price of tickets, lots of fun, and you get to see South Dakota’s Black Hills in a way you won’t otherwise.
I watched a YouTube video that gave a great definition of the Engineering Method.
