Population genetics is the branch of genetics which studies the genetic composition of populations. It brings together genetics, evolution, natural selection, breeding, statistics and mathematics. It's one of those rare crossroads of multiple disciplines that gives a wider perspective to ourselves and nature.

It doesn't just answer the question of what we are, but also why we are as we are.

One of the most epic visualisations in literature must be the moment when Dr Frankenstein reanimates a dead body that is to be his monster. More than a century after Mary Shelly, the link between electricity, chemistry and biology still enthralls us. Some of the mystery was solved since, others have yet to.

But it does not take much time for us to learn the basics of how Frankenstein gave life to his monster...

If you dig down into the Earth far enough, you will notice the gradually decreasing complexity of life that came before us, interrupted now and then by periods of extinction. But what if there is a gap of complexity that can't be explained? A sudden, inexplicable layer of the strangest most alien creatures to ever walked (swam?) the Earth? And what's more, before that, there is practically nothing in comparison to them?

​Have we found the moment when God's hand meddles in Earthly matters?

Chemistry, to put it simply, is just another application of physics. It's what happens when nature uses the laws that governs it to form tangible things. Things that reacts upon and interacts with one another.

And since the most basic application of physics is the atom, we must first look into this fundamental building material to understand even the most basic of chemical principles.

Pi is one of those constants in the mathematical world. And because of that, it often appears in nature, particularly any that involves curves and ​spirals. But it would be too easy to derive pi from those very things - they are ordered, unchanging, predictable.

But what if pi can be derived from a series of improbable, unpredictable actions?
