I was watching the London Marathon and saw one runner dressed as a chicken and another runner dressed as an egg...
I thought, "This could be interesting."
Powder metallurgyIn 1828, the Bakerian Lecture at the Royal Society in London, was presented by William Hyde Wollaston wherein he described the method of powder metallurgy he had devised in 1805 to produce platinum from its ore. This provided the means to produce the metal in a malleable and ductile form, though he had kept the process a commercial secret, and had made a comfortable living providing the metal in a useful form. He took a uniform powder after carefully removing impurities, compressed it in a powerful toggle press, dried it, and forged it at high heat. Now in ill-health, he ceased business operations and was making the process public. His paper won him the Royal Medal of the Society. He died the following month, on 22 Dec 1828.« |
