A new origin for trigonometry

So who invented trigonometry? The Greeks according to many resources, articles and books. The Greek astronomer, Hipparchus, is often credited with compiling the first table of trigonometry in 140 BC, and is known as the father of trigonometry. There are however some references in early math history books that the Greeks may not be the first and they might’ve gotten their knowledge from much older civilizations. For example, David Eugene Smith notes in History of Mathematics, Vol II, states that according to the Greek historian Herodotus, the Greeks obtained their sundial (that relates to trigonometry), obtained from Babylon. Smith notes that “this is very likely true, for we know that the Egyptians used a sun clock as early as 1,500 BC.”

A classic song reinterpreted

Once in a while, you hear a familiar old song, and it’s as if you’re hearing it for the first time. That is exactly how I felt when I first heard the cover of classic song The Sound of Silence by Disturbed, recorded in their 2015 album called Immortalized. The singer is David Draiman, lead singer of Disturbed. Here is the official video music released in 2015. As of this writing in April 2017, it has more than 208 million views!

Let’s lose Colombus Day

Please lets LOSE this Columbus Day shenanigan. Most of it is based on falsified and twisted history fed to the kids and public. It’s nothing but a shameful reminder of the genocide, rape, slavery and destruction that Columbus and his gang committed in the supposedly newly discovered land.

Woody Allen on Life, Happiness & Love

I came across excerpts of an interview with Woody Allen (and Owen Wilson) about Midnight in Paris, Woody Allen’s wonderful 2011 romantic comedy, for which he won an Oscar for the best original screenplay. Midnight in Paris is the story of a Hollywood writer, Gil (played by Owen Wilson, essentially playing a younger Woody Allen) on vacation in Paris with his fiance. Gil who’s having trouble writing his book, is in search of that elusive happiness. He falls in love with Paris and as he drifts away from his fiance, he starts fantasizing about Paris in 1920s. Somehow every night after midnight, he ends up hanging out and partying with the literary and artistic greats of the early 20th century such as F. Scott Fitzgerald, Ernest Hemingway, T.S. Eliot, Edgar Degas, Henri Matisse, Pablo Picasso and Salvador Dali, among others, in the Parisian cafes and lounges of 1920s. Read more ›

Walking in the rain

It was raining hard when I left the bar late night. After a fairly long and warm summer, the Fall had finally arrived with the first rain of the season. I paused and contemplated for a moment by the door…it’s uncomfortable to get wet. I had intentionally parked my car fairly far earlier that eve to make myself walk. I started walking — down Montgomery, passed the pyramid and onto Washington. I could feel the big drops on my head. But after the initial discomfort and chill, it actually felt good.
