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.
What Causes Hypnic Jerks?
Often when we are about to fall asleep, we experience a kind of a falling sensation which causes us to wake up with a start. It happens to almost everybody, and the sensation is known as a hypnic jerk. It also sometimes happens when you tilt the chair you’re sitting on too far—somehow you can sense when you’re about to fall, and you wake up with a hypnic jerk. We really have no idea what causes them or whether they serve any modern purpose, but science has come up with some interesting theories.One hypothesis suggests that our bodies developed this mechanism when we used to sleep on branches or high ground, and it was meant to help us avoid a fall. But there is no evidence to support it, and humans rarely slept on trees or precarious cliffs as a matter of habit. Other theories suggest that it happens because of the slowing down of the body’s processes when you fall asleep, but again, there are no scientific studies to support that claim either.
1) Do not bring your phone to bed
Smartphones are a double-edged sword. As cool as it is to surf the web at your convenience, it can take up a lot of your time and attention, particularly how we do it in bed.
We go to bed with the intention of sleeping, but we tell ourselves, “Just a little Facebook-ing” or “Let me see what’s on Buzzfeed”. Not only does this spoil your eyesight (because we switch off the lights first right?), but unknowingly tires us out as we get less sleep.
Stop it. Go to bed without your phone from now on. Just go to sleep. You’re going to have way more energy the next day.
2) Delete social media apps
There has been a trend of people staving off social media. It’s a great habit, but doing it cold turkey may be a little too much.
Instead, delete the mobile apps. Instagram, Twitter, Facebook or whatever. Get rid of them. You can use them at home in your computer.
This habit is going to open up your eyes, your mind as you start connecting with both people and the world when you head of the house. You’d be surprised how much you’re actually missing out.
3) Break routine
The idea here is to constantly try something different at random parts of your lives. It could be taking a different route to work or listening to a different playlist that’s not your favourite in your phone.
When you break routine and do something different, you automatically grow in life.
