How Does Turbulence Work?
Everyone has gone through a flight where the pilot asks you to tighten your seat belts because of excessive turbulence, but even though it is so important to things like air safety, we just have no idea how it works. It has perplexed scientists to such an extent that Einstein once famously said, “Before I die, I hope someone will clarify quantum physics for me. After I die, I hope God will explain turbulence to me.”The problem is aggravated by the fact that wherever the need to study turbulence arises—like in jet propulsion—chemical reactions take place alongside the high pressure and extreme conditions, which makes it difficult for researchers to study the exact conditions needed to produce turbulence. If somehow we could figure it out, it could be applied to a variety of uses since turbulence occurs everywhere in nature. Maybe one day we’d even be able to predict hurricanes or other natural disasters with accuracy, thus minimizing the damage and finally scoring one over nature.
Why Do Cats Purr?
We’ve shown before that cats don’t always purr when they’re happy, but the mystery goes way deeper than that. There is no purring organ in the throat of a cat, and even though extensive research has been done on the function itself, the exact origin of the function in the anatomy of cats is still unknown.It’s theorized that they might do it by the constriction and dilation of the larynx, but no evidence has ever been provided to prove or disprove that theory. It was, however, found that the frequency of a cat’s purr falls somewhere in the range required to accelerate bone regeneration and healing, so it might just be a healing superpower that we had no idea even existed in the animal kingdom. That might also explain why we take it to be a happy sound, as the frequency is not just beneficial for the cat—it tends to make us happier as well.
