The second article of “Data Science for Everyone,”: an article series to address data literacy in the community.

The previous articles in this series (Getting To Know Your Data — Part 1) laid the foundation for understanding some fundamental concepts on data.

Let’s continue discussing different perspectives we can look at data to enhance our understanding of it.

In the timeline of human history, we almost took data for granted. However, with the advent of computer and information technology in the late 20th century, the value of data became more pronounced. With the advancement of big data analytics, data mining, artificial intelligence, and machine learning our appreciation of data significantly increased and continued to be rising. This lead…

Celebrating Pi Day (March 14th), the annual celebration of the mathematical constant π, and International Day of Mathematics having some fun with computer programing.

Why do we celebrate Pi Day?

March 14th of every year is a special day for the science community. The day is written in month/date format (3/14) resembles the first three significant digits (3, 1, and 4) of the mathematical constant π≈3.14.

In 1988 Larry Shaw, a physicist at the Exploratorium, organized the first known Pi Day Celebration. The United States House of Representatives in March 2009, supported Pi Day with the resolution titled“H. RES. 224 Supporting the designation of Pi Day, and for other purposes,” and March 14th is recognized as National Pi Day. …

Mentorship has a long history in our human civilization. In education, religion, governing, professions, and families, the mentorships helped carry forward the knowledge, wisdom, and good virtues from one generation to another. In other words, mentorships are the critical links connecting generations in the timeline of our civilization. When those links are broken or weakened, the progression of humanity is hindered.

“You cannot hope to build a better world without improving the individuals. To that end, each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty…
