What is Data Science?

There’s no question that “data science” is becoming more and more popular. In fact, Booz Allen Hamilton (a consultancy) found: The term Data Science appeared in the computer science literature throughout the 1960s-1980s.

The Complications of Spoken Confidence

Sometime last year, I came across a speech from the 2015 Toastmasters World Champion, Mohammed Qahtani. If you have a few minutes, I really suggest you take the time to watch it.

To be honest — I underestimated how long it would take me to prepare for my seminar in International Relations. Aside: if you want to challenge yourself, […]
