While making Egyptian fattah in Episode 5.5, the wine that Elizabeth drinks is labeled "Omar Khayyam". While "Omar Khayyam Cabernet Sauvignon" is an actual wine, Omar Khayyam was an 11th -12th Century Persian mathematician, astronomer, and poet. One of his poems is called the "Rubaiyat of Omar Khayyam". This ending of this poem - Tamam Shud (translated, "Finished" past tense) - was found torn from a copy of the Rubaiyat on an unidentified man who was found dead on Somerton beach, South Australia, deceased from what looked like poison. He has never been identified, and is suspected of being a Soviet spy. The case is known as the Tamam Shud case.
Lotus 1-2-3 was the first big "killer app" in the micro computer industry of the early 1980s. At that time, personal computers were still very expensive (after adjusting for inflation, they would be about $6,000 a unit). It was difficult for companies to justify spending large sums on a large number of personal computers until applications like Lotus 1-2-3, which promised such a dramatic increase in worker productivity. It was apps like Lotus 1-2-3 that turned personal computers from a niche product into an indispensable must-have for businesses, and made companies like Apple and Dell what they are now. And without the success of the PCs in the early 1980s, there would be no tablet computers and smart phones now.
