Searching For Meaning In Randomness
What do we mean when we call an event random?
Most people view randomness as a fundamental property of the universe, but is it just a label for our own lack of knowledge? Whether it is a weighted coin toss, a scratch card, or the digits of Pi, unpredictability usually emerges from rules and patterns that sit just beyond our perception.

What We Said To Aliens
What happens when humanity dares to shout a cosmic “hello”? Could it help alien civilisations decode human mathematics, our DNA, the blueprints of who we are? And why did we blast the 3-trillion-watt message into the stars in the first place…only to never try anything like it again?
This is the story of the Arecibo message.
