Why did Golf balls get dimples?

Golf Balls

The first ball with which Golf was ever played was a ‘hairy’ ball (though mostly forgotten now). Most people would say that Golf was played with ‘feathery’ or ‘featherie’ ball when it was introduced.  and had dominated golf for over 200 years. In the first four hundred years of golf, there were four types of balls used – the Hairy, the Feathery, the Gutty and the Haskell.

The invention of golf ball dimples happened accidentally. In the mid-1800s, the most widely-used golf balls then were known as gutties, which were first created by Robert Adams Paterson using molded tree sap of Gutta Percha tree getting the name Gutty from the name of the tree.

When golfers inevitably dinged up these balls, they found that the damaged ones had more consistent ball flights than the new, undamaged balls.

After that discovery, golf ball makers began etching raised protrusions into balls. In the early 1900s, another inventor found that indentations in golf balls performed far better than raised protrusions. In 1905, an English manufacturer named William Taylor registered a patent for a golf ball dimple design. Before long, all golf balls featured dimples that would be more or less recognizable today.

As ball technology advanced, so too did dimple science. In the modern era, dimple patterns are thoroughly tested using high-tech equipment to find the optimal design for distance and control.

So why are dimpled balls better than the smooth ones?
Golf ball dimpled
As a lay person we would think that smooth golf balls would travel farther than the dimpled ones we use today. But that would be wrong. And there’s actually some fun physics behind the dented ball design. As a smooth ball, without ‘dimples’ flies through the air, the air comes in contact with its front, travels smoothly over it and separates from it at the back.  That separation leaves a “turbulent wake region” behind the ball, which creates a drag on the ball. If ‘dimples’ (small hollows which are present on the surface of a golf ball are called ‘dimples’). are added to this imaginary smooth ball, the drag reduces because the turbulent wake is minimised.
A smooth, solid ball won’t fly nearly as straight or far as a golf ball with dimples. The dimples on a golf ball “create a thin turbulent boundary layer of air that clings to the ball surface and allows a smooth flow of air. Due to the thin layer of turbulent air, the dimples create on a golf ball in flight it travels straighter and farther.  Dimples also help with the lift.

While on the subject of Gold balls, let us seek answers to a few curious queries a few of us might have:
Q. How many Dimples are there in a Golf Ball?
A. There cannot be a simple number as the answer to this question. The number of dimples varies depending on the model and manufacturer. Most often, the number of dimples per golf ball falls between 300 and 500. The 2017/18 model of the popular Titleist Pro V1 has 352 dimples on it, while Titleist’s other flagship ball from the same year has 328 dimples. A  manufacturer created a record of sorts with a whopping 1,070 dimples on a golf ball.

Q. What size and shapes are the ‘dimples on a Golf Ball?
A. The size of golf ball dimples is  measured by their depth. The average depth of a golf ball dimple is roughly 0.010 inch. The circumference of dimples also varies from model to model. While most dimples are spherical in shape, they don’t have to be. Some even have hexagon-shaped dimples. Golf ball dimples, essentially, are required to have a symmetrical arrangement and must be within a specific range of radius and depth for optimal performance.

Q. What is the weight of a Golf Ball?
A. The weight of a Golf ball varied dramatically for the most part of the game’s history. With older golf ball designs dating back hundreds of years, the most consistent thing about their weights, shapes, and sizes was the inconsistency. But in the modern era, as with all the Games played professionally sizes of almost all things are strictly specified. Golf’s governing bodies have set out clear regulations for how much a golf ball shall weigh.  As per current regulation, a golf ball is required to have a mass no more than 1.620 ounces, or 45.93 grams.

Q.What is the size of a Golf Ball?
A. The general size of golf balls has a  history similar to the golf ball weights. In the past, there was great variation among golf balls. But now balls are required to have a consistent size. According to the existing rules, the diameter of a golf ball must not be less than 1.680 inches, or 42.67 mm.

Why does Facebook have a blue color scheme?

Here I am to quench your curiosity about :

Why does Facebook have a blue color scheme?

Please be prepared to know the shocking surprising answer!

Mark Zuckerberg is redgreen color blind!

Yes! You read it correctly, Mark is colour blind. Zuckerberg being red-green colour blind,  means the color he can see best is blue. And that happens to be the colour that dominates the Facebook website and mobile app. He had in an interview very candidly accepted:
“Blue is the richest color for me, I can see all of blue.”

Another important commercial factor for using blue colour may be the fact that most colours tend to distract the viewers. Blue on the other hand acts as a transparent background to the main content as visible to the human brain due to which many popular websites tend to use the blue colour. It can easily be called a webmaster’s favorite colou r. Blue colour is also sometimes referred to as ‘Nirvana’ for the brain.

All these factors make blue a prominent colour on Facebook.

Can an inanimate object grow?

Can an inanimate object grow? Sounds kind of a silly question, isn’t it? Then why am I asking it publicly? Is there a catch or is it a trick question?  Please read on to quench your curiosity…..

Please answer, ‘True’ or ‘False’ for the following statement:
eiffel tower true false
My answer is : TRUE! What say you?

You may call it a trick question because The Eiffel Tower does gain height and it does not!

Tour_Eiffel_Wikimedia_Commons_(cropped)

Yes, it is because Steel expands on getting hot and contracts when cold.
Believe it: The Eiffel Tower is 17 centimeters, yeah, full seventeen cm taller in summer daytime than winter. The height of the Eiffel Tower is 324 meters on average-changes depending on the season. Did you notice that the height of an inanimate object is written as ‘on an average’! When the hot summer sun beats down on it, thermal expansion causes the metal to grow. Well, and it is back to its original height when it cools down!

 

 

 

 

So, we all know metals expand when heated and contract when cooled. Mostly we read it in academic books but never perceived it in real life as the expansion is not perceptible to naked eyes. We all know all metals rather all materials expand (increase in size) in a certain measure when subjected to high temperatures — and contract when cooled. This is a basic thermodynamic fact: molecules always vibrate and when heated, this vibration increases, slightly expanding the bulk of the material. Mostly we read this in academic books but never perceive it in real life as the expansion is not perceptible to naked eyes. The increase in height of The Eiffel Tower cannot be perceived by just looking at it. It is scientifically measured.

However, there is an area where we can ‘see’ this expansion phenomenon.

Remember the clickety-clackety sound we hear when traveling by train. This sound is due to the joints we have in rail tracks duly joined by fish plates. When a train passes over them, we hear that sound. The sound comes in a rhythm as the joints are almost at the same interval because track lengths are mostly fixed.

trainline gap

 

At this joint, a very small space is left between two rail-track ends. This gap at the joints is to compensate for the expansion in rail-tracks made of steel. These metal rails expand due to summertime rise in temperatures and also due heat generated when a train passes over the track. People in the know claim that the gap gets partially filled in summers and is visibly perceptible. It reverts to slightly bigger gaps in winters.  

I must add that with the advent of new technologies in construction techniques and building material, tracks no longer need to have a gap when constructed with special alloys formulated for this purpose as the same remains unaffected due to temperature.

However, our Eiffel Towers still continues to stand tall and slouch a bit!

Ohh!! It is too spicy…

chilly mouth

Had a bite of spicy food & it’s burning your tongue and setting you mouth on fire! You lunge for water but water hardly seems to help. Why?

And
What would be a better remedy? Are you eager to quench your curiosity and be prepared for the future? Read on….

greenredchillyFirst let us understand what causes the ‘fire’ in our mouth when we eat spicy food. Spicy foods contain a substance called ‘capsaicin’ which comes from chillies. Capsaicin stings taste buds and brings on the ‘hot’ sensation.

cold water

Cold water is not effective to mitigate spiciness because water like liquids spread capsaicin and are likely to increase the burning sensation.

So what to do?

Glass of milk

Have milk!

Yes, have milk! Milk binds with the hot capsaicin oils to disperse them.

Are you willing to quench your curiosity about the title number? Read on…

Okay, here is a hint: This is related to the puzzle: SUDOKU!!!
Well, theoretically this is the number of total possible solutions or for that matter  number of Sudoku puzzles possible!

There is a further clarification however:
When mathematicians took away rotations, reflections, permutations and relabeling, which takes away the same puzzle in just a different form, the number of solutions was drastically reduced to just 5,472,730,538 though still a very large number!

Stay tuned for such interesting curiosity quenchers!
