The Price of Metals

Jewelry making is getting more expensive! Gold has reached record prices as $1002.50/ounce, silver is at a whopping $20.68/ounce, and even our go-to base metal copper is creeping up at now $3.85/pound. According to NPR, representatives from the U.S. Mint were on Capitol Hill today to discuss using a new alloy for the penny since producing the one cent coin now costs 1.7 cents.

Happy Pi Day!

Today, on March 14, we celebrate pi, or 3.14…., the ratio of the circumference of a circle to its diameter. Not only is pi an irrational number (which can’t be expressed as a fraction and so is never-ending), it is also a transcendent number (meaning no algebraic operations can produce it). Coincidentally, today is also Albert Einstein’s birthday.
