Ever wondered why frogs 🐸 croak so much during the night? Those sounds we find soothing (or sometimes irritating) are actually a fascinating mix of biology, love, & a touch of competitive spirit!
Long story short, it's all about romance for frogs. Male frogs croak to attract females and to claim the best real estate in their town. These amphibian Romeos even have croaking competitions, where the biggest croak usually wins the lady's heart.
Nighttime provides a safer stage for their performances. Cooler, humid conditions prevent frogs from drying out, and predators are too sleepy to spoil the mood. 😛
So, next time when you hear this nighttime orchestra, just know it's frogs giving their all to find their one true love! 🫰

Linus Torvalds humorously named Git after himself. In British slang, "git" is a derogatory term meaning an unpleasant person. Torvalds has been quoted saying, "I'm an egotistical bastard, and I name all my projects after myself. First Linux, now git.
Why are clouds normally white or darker in a rainy day? Why the sky looks blue? Here's the story:
Clouds are made up of millions of tiny water droplets & ice crystals. These particles are incredibly small, about 10 to 20 micrometers in diameter, which is roughly the size of the wavelengths of visible light. When this sunlight hits the tiny water droplets in the cloud, it gets scattered in all directions. This scattering is called Mie scattering, it treats all the colors of sunlight equally. So, instead of scattering just the blue light (like what happens with the sky), it scatters all the colors together making them appear white.
On a rainy day, clouds look gray or dark because when clouds accumulate more water droplets they become more efficient at absorbing & blocking sunlight. Instead of the sunlight passing through and scattering evenly, as it does in thinner clouds on sunny days, the water droplets in rainy clouds absorb more light. This absorption makes the clouds look denser & darker from the ground.

Ever wondered what really happens inside popping popcorn? It's really fascinating 😬
So inside each corn kernel, there's a germ & endosperm - basically, a tiny plant & its food which contains about 14% water. When heated, the water inside turns to steam, causing pressure to build up within the shell.
Picture the shell as a mini pressure cooker, containing the steam until the pressure becomes too great. At around 180°C, the internal pressure reaches nearly 10 times the normal air pressure, & the starch granules turn into a pressurized gelatinous goo.
Eventually, the pressure causes the shell to burst, releasing the steam & causing the goo to expand explosively. This is the moment when the kernel transforms into the fluffy popcorn we all love. As it cools, the fluffy foam solidifies, ready to be munched on during your favourite movie. 😇

Fun fact: The lighter was invented before the matchstick!
In 1823, Johann Dobereiner came up with the first lighter, it was known as "Dobereiner's lamp" and used a chemical reaction involving hydrogen and platinum to create a flame but it was bulky & expensive. Then in 1826, John Walker was like, "I can do better!" and invented the matchstick.
It was cheaper, portable and way less likely to explode in your face!

Ever wondered why we eat popcorns at the movies? 🤨 Let’s uncover the story!
In the early 1900s, the first movie theatre was known as "nickelodeons". As movie theatres gained popularity, they modeled themselves after grand opera houses, aiming for a sophisticated atmosphere by prohibiting food inside. Meanwhile, popcorn was already a favorite street snack thanks to Charles Cretors’ steam-powered popcorn machine introduced in 1885.
During the Great Depression of the 1930s, theaters faced financial strain and turned to popcorn as a solution. Selling this affordable treat became a significant revenue stream, helping theatres survive tough economic times. Today, popcorn and other concessions generate more profit for theatres than ticket sales do.
