### Our Random World—Probability Defined

While it’s nice to think that our challenge in life is to get rid of uncertainty and be in complete control of everything, that is not going to happen. One of life’s real challenges is to deal with the uncertain and the unknown in some sort of an effective way; and that is the realm of probability. […]

### Understanding Big Data: The Three V’s

Big data is often defined as having three v’s: volume, velocity and variety. We stand in a data deluge that is showering large volumes of data at high velocities with a lot of variety. With all this data comes information and with that information comes the potential for innovation. Let’s take a closer look at these “3 V’s” of big data and how they help us understand this highly complex field. […]

### The Nature of Randomness
