Subtle Differences

By Anupum Pant

Who’d have thought that a fun website like 9gag could teach you something useful. This is an artwork that I first saw on 9gag and wanted to find where it originated from (to give the artist its full credit). I believe, I Raff I Ruse is the blog which published it first. I could be wrong, but then the apparent source itself attaches no text that could confirms anything. And then it probably went on NPR, and consequently spread all over the web.

The artwork illustrates subtle physical differences between certain kinds of animals which look very similar to the untrained eye. It’s a very simple thing to know and you should definitely know it. The whole list includes differences between:

  • Ape and Monkey
  • Frog and Toad
  • Dragonfly and Damselfly
  • Ant and Termite
  • Wasp and Bee
  • Turtle and tortoise
  • Alligator and Crocodile

The Turtle and tortoise difference was one of these seven differences which I knew for sure. Then, I can definitely tell a wasp from a bee, an ape from a monkey, and an ant from a Termite, I still wasn’t very confident about the others. I bet you also knew at least one of these differences. And I hope you didn’t know at least one because I wish you learn something from this post.

The Leaping Shampoo Trick – Kaye Effect

By Anupum Pant

This is really interesting and I can’t explain why. You’ll have to see it for yourself.

Long time back, researchers at the University of Twente in The Netherlands thought of something very weird. They decided to drop a thin stream of shampoo from a height of about 20 cm, ended up discovering an absurd physical effect and winning great accolades for it – The Kaye effect.

The seemingly weird effect can fairly easily be achieved at home by dropping a thin stream of shampoo on a relatively hard surface. In individual steps, this is what happens when you do it:

  • As the stream gets collected, it forms a little shampoo heap.
  • Amazingly, and counter-intuitively, a secondary stream ejects off the heap.
  • The mythical secondary stream becomes bigger, shoots further.
  • And finally hits the incoming stream – this collapses the Kaye effect.

Of course, everything happens really fast. But, if you look at it on extremely slowed down film, you’d see the individual steps happening one after the other.

True, the secondary stream collapses too quickly, scientists weren’t happy about that either. So, they tried tilting the hard surface slightly to achieve a stabler version. Lo! And they had a stable Kaye effect.

This happens because due to certain physical forces the viscous liquid becomes slightly less viscous temporarily – they call it shear thinning. As a result, it causes a new stream to emerge. May be the same effect could be achieved with other thicker liquids like lava, ketchup, whipped cream, blood, paint, and nail polish. But, then lava is too dangerous, and others (barring blood and paint) seem to be too thick. I’m guessing, dropping thicker ones from a higher place could make this happen.

If you find this interesting,you’d definitely love the egg and milk effect, also the chain of beads defying gravity.

Do Not Paint Your Walls Pink

By Anupum Pant

Like I’ve told you once, there is no pink. Still, we do see the colour pink and there’s no denying that. Don’t call me a sexist for saying this, but it’s true that the colour pink is associated with femininity. Otherwise the colour is also known to generate feelings of caring, tenderness, and love. If everything we know about pink is somewhat positive, then why isn’t it a good idea to paint your walls pink?

Let me start with a little story.

Hayden Fry and the Pink room

Hayden Fry was an American football player and later he went on to become a coach. In the late 70s he started coaching the University of Iowa football team. Now, the particular thing to note about Fry was that in the year 1951 he had graduated from Baylor with a degree in psychology.

Since he had graduated in psychology, Fry probably knew some good ways that he could use to mess with the opposing team’s brain. And then he decided to paint the walls of the visitor’s locker room at Iowa’s Kinnick Stadium, with the colour pink. The walls, floors, toilets, ceiling and everything else in the locker room was painted pink. As a result, the home team started doing significantly well at football games (later the practice of painting locker rooms pink was outlawed).

Some say, he used pink to paint the visitor’s locker room because he knew that the colour pink had a calming effect on people. But I think he was relying on something deeper. He was probably trying to cash on the results of a study that was done by Prof. Alexander Schauss in the year 1979.

The Effect of Pink Colour

Prof. Alexander Schauss started a study with a couple of volunteers. He divided the group into two equal halves. All of their strengths were measured by asking them to use their arms against a counter-force and by asking them to squeeze a device called a dynamometer.

After this, for a minute, the first half had to stare at a dark blue colour and the other half stared at pink. Their strengths were recorded again.

A remarkable decrease in physical strength was recorded among the people who were given the colour pink to stare at. The participants were not aware of the effect it had on them.

Probably it were those pink walls and pink floors at the visitor’s locker that made the opposing team physically weaker and helped Iowa win.

Conclusion

Colours certainly are one of those subtle forces which change the way we think, feel, and behave. Pink has been proven to make you weaker physically. So, unless you wish to be weaker, you wouldn’t want to paint your walls pink! How about blue? It is a simple choice.

Now I think even writing an article about pink and having your brain think about the colour makes you weaker. Seriously, I feel like I need rest after writing this. Phew!

Hit like if you learnt something.

Cute Aggression – Hugging The Life Out of Your Puppy

By Anupum Pant

Don’t you feel like pinching the cheeks of a chubby little baby or hugging the life out of your puppy? Even if a kid might find it unpleasant you pinching its cheeks really hard, or even if you’d not want to hurt a little kid, you’d still be bubbling to do it. What is it that forces you to vent out a physical reaction towards cuteness?

Most of us do and science proves that intense cuteness can often manifest itself as aggression. Rebecca Dyer, a graduate student in psychology at Yale University, has coined the phrase cute aggression for this feeling. Scientists are not yet sure on what causes this. According to them:

“It might be that how we deal with high positive-emotion is to sort of give it a negative pitch somehow”

Or probably you, in some way, want to take care of something by ensconcing it in your arms. And when you see and are not able to do it, you vent it out on bubble wrap?

Researchers carried out a study involving bubble wraps. It was found that people who were shown slides/videos of cute animals popped higher number of bubbles than the people who were shown something not so cute, funny or neutral videos.

A YouTube channel, SoulPancake, actually recreated the experiment in their studio and recorded positive results. It was found that cuteness evokes a physical reaction in most people.
