Answering casual dilemmas with

SCIENCE :D

Casual dilemma 1- Why is the sky blue?

• When you look at the night time sky, it's black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky doesn't remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear?

Why can’t it be red?

Or green?

Or even yellow?

But BLUE ?!

Rayleigh Scattering

What is that?

• A physical phenomenon that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light

• Thus, shorter wavelength will scatter more than the longer wavelengths

About Sunlight

• Sunlight is made up of all different colors of light.

• The colors of the rainbow are the "basic spectrum" from which all the light we see is composed.

So how does it give the sky its blue?

• Shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light)

• Thus, the result is a pale blue as violet is less efficiently detected by the human eye

So how does it give the sky its blue?

• Red and yellow light which are not scattered away are visible, giving the sun itself a slightly yellowish hue

Casual Dilemma 2 – Did the Chicken or the Chicken Egg come first?

• If there is no Chicken, there would be no Chicken Egg.

• But if there is no Chicken Egg, there would be no Chicken!

• Which came first?

The answer?

CHICKEN !

Why?

• Protein found only in a chicken's ovaries is necessary for the formation of the egg

• Therefore, a Chicken Egg can only exist if it has been created inside a chicken

However…

If its referring to EGGS and not specifically CHICKEN EGGS…

EGGS would have came first!

Why?

Assumption of evolution:Bird laid an egg that had a genetically mutated bird with this new protein. This mutated bird was the first chicken because it was the first bird to lay a chicken egg.

Why must it start with a egg?

Mutation doesn’t happen in full grown animal without negative effect because our body is designed to get rip of defective cell via apoptosis. Mutated cell that fail to trigger the apoptosis will develop into tumour.

Why must it start with a egg?

Its also a reason why people don’t wake up and find that he had a sixth finger, they have to be born with it.

Interesting Theory

• Tyrannosaurus Rex, evolved into the modern-day chicken with scientific backing with the discovery of some pre-historic collagen.

• Since Tyrannosaurus Rex lays eggs as well, it still supports that the Egg came first.

Why learn about answering the questions?

"Understanding how chickens make egg shells is fascinating in itself but can also give clues towards designing new materials and processes,""Nature has found innovative solutions that work for all kinds of problems in materials science and technology — we can learn a lot from them."
