Nikola Tesla and the world you didn’t know he built

Whether you know it or not, but every time you turn on a light, scroll through your phone, or stream music wirelessly, you’re living in the legacy of Nikola Tesla.

Most people know the name. Fewer know the man. And almost no one realizes just how much of our modern world quietly rests on his shoulders. Often remembered as a brilliant but eccentric inventor, Tesla’s real contributions run far deeper than the lightning bolts and dramatic experiments history tends to highlight.

He didn’t just imagine the future. He helped build it – quietly, profoundly, and in ways we’re only beginning to fully appreciate.

Does Reality Exist Without Observers?

If a tree falls in a forest and no one is around to hear it, does it make a sound? This age-old philosophical riddle has found fresh foundation in modern physics, where the question morphs into something even stranger: Does reality exist without an observer?

At first glance, you might think the answer seems obvious. Of-course reality exists independently of us; planets orbit stars, black holes devour matter, and the red spot storm on Jupiter goes on whether or not we’re watching. But quantum physics, with its counterintuitive effects and observer-based mathematics, complicates this seemingly simple answer. Let’s explore this rabbit hole.

Time – Why it only moves forward (or does it?)

Have you ever wondered why, we can’t rewind our lives like a video? Why spilled coffee on the desk doesn’t spontaneously return to the mug or why vapor doesn’t retrace its path into ice cubes? The everyday experience of time “flowing” in one direction feels so natural that we barely question it – until we pause to ask: Is time truly forced to march forward, or might there be cracks in the arrow that point otherwise?
