Before 1974, if someone claimed to be a billionaire, you needed to confirm if they were talking about the American billion or the British billion.

Same with costs of large projects, country debts etc.

Hedy acted in 30 films and during the Second World War she co-developed a frequency-hopping guidance system for American torpedoes, the principles of which are used in Bluetooth and WiFi technologies today.

She was granted patent # 2,292,387 for a "Secret Communication System”

This is such a great nerdy joke - topical, scientifically correct AND funny.

This is the 50th issue of the newsletter. Here’s some fun facts about fifty:

• The atomic number of tin - Tin has symbol Sn (from Latin stannum). When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals.

• Fifty is the smallest number that is the sum of two non-zero square numbers in two distinct ways - 50 = 1² + 7² = 5² + 5² . It is also the sum of three squares and the sum of four squares. Hit reply and tell me which ones.

• 50 is a Narayana number - named after Canadian mathematician T. V. Narayana (1930-1987). More details about Narayana numbers at https://en.wikipedia.org/wiki/Narayana_number

• The fifth magic number in nuclear physics - a magic number is a number of nucleons (either protons or neutrons, separately) such that they are arranged into complete shells within the atomic nucleus. As a result, atomic nuclei with a "magic" number of protons or neutrons are much more stable than other nuclei. The seven most widely recognized magic numbers as of 2019 are 2, 8, 20, 28, 50, 82, and 126.

• 50 states in the United States of America.

• There is no country with international country dialing code 50 - because there are 10 countries with codes 500-509

That’s it for this issue.
