When I was a child, many unusual questions used to trigger my mind, some I got the answers and rest are still unexplored. Human is a social animal with brains. We have got a special ability, we can reason. In our day-to-day life, we come across several stuff which we accept it without knowing the cause of that activity. But the question is why? How?
In this article, we will see the reason behind some of the activities that we see every day but never questioned about it.
Why the wheels of any vehicle are circular?
- Quite interesting! I noticed it when I was 12 years old. Well, everyone uses a cycle, bike or a car, watching the wheels every day. But, why can’t the wheels be rectangular or square? Why circular? There is the force that opposes every force called friction force. We can walk, run & stop; all due to this force. Wheels of the automobiles are made circular to reduce the frictional force. On a circular body, rolling friction acts which is less than the sliding friction (a type of friction that acts on all bodies other than circular) which is responsible for the wheels to be circular. If wheels would have some other shape, sliding friction would come into picture increasing the resistance in movement of automobiles.
Why tube light blinks before turning ON?
- Every day we come across this phenomenon but the reason remains unnoticed. A tube light has a low-pressure mercury vapour with a phosphorous coating, white in colour which we can see from our eyes. When the tube light is turned ON, it flickers. That flicker is caused because the gas inside the lamp is relatively cold and cannot establish glow discharge between the two electrodes. Once the heat is developed, gas ionizes and gives out the ultraviolet light enabling the phosphorous coating to glow.
Why the moon looks bright yellow at night?
- Moon is connected to humans involving different emotions and expressions. Moon does not have its own light. It is just an illusion. Then, how does it shine? That bright colour of the moon is due to the reflected light from Sun which bounces off the dark grey and bumpy surface of the celestial body, falling on our eyes. The shocking fact is that only 3% to 12% of light is reflected from the surface of the moon but still the brightness is more than a star. We can see the moon during day time but we can’t see the stars.
Why do stars twinkle at night?
- Twinkle- Twinkle little star….. The poem taught to every child always tickled my mind when I was 16. Our Earth atmosphere is very turbulent and made up of different layers of air moving in all directions at different intensities. Light from the stars travel a very long distance before falling on our eyes. When it passes through the atmosphere, it bends due to refraction which makes it appear to twinkle. The Scientific name of the twinkling of stars is ‘astronomical scintillation’. Thank God! The poem was not written by a scientist.
Why the sky is blue in colour?
- The rays of the sun are made of 7 colours (Violet, Indigo, Blue, Green, Yellow, Orange, and Red). As the white light passes through Earth’s atmosphere, it collides with particles of air. The different colours or wavelengths of light are scattered by this collision by different amounts. Blue light (shorter wavelength) is scattered more than red light (longer wavelength).When sun is high in the sky, blue light is scattered in all directions and sky appears blue.
How water comes inside the coconut?
- Clusters of coconut palms thrive on seashore outside the tidal zone provided there should be a plenty of subterranean fresh water. As the fresh water accumulated by the roots is conveyed right up to the crowns of the coconut palms through osmosis process, any dissolved salts which exist in that water is eliminated through natural filtration. The water inside the coconut is actually ‘endosperm’ or the food or the nourishment for the coconut’s growth. As the coconut ripens the water becomes less pleasant to drink.
How does water come on Earth?
- After the big bang almost 13.8 billion years ago, the energy that sparkled in the Milky Way galaxy lead to the formation of Earth. That time Earth was boiling at a very high temperature. The water we have today came into existence much after the formation of the blue planet (Earth). Comets and asteroids can contain ice. The collision of wet comets and asteroids is responsible for the existence of life-giving liquid, “water” on Earth. The study shows that meteorites from Vesta (a group of meteors near to Jupiter) have the same chemical makeups (rocks) as that of our Earth. The mystery is not yet solved, but suspects’ asteroids.
How a program recorded in a studio reaches our Television sets?
- We enjoy watching different programs on T.V but we never think of the engineering behind the telecasting of any program. There are three divisions of a Television station:-
- Earth Station
A studio is the action area of artists where they perform any act. When the program is recorded it is sent to the Earth Station via cables. Earth station is a terrestrial terminal station designed to uplink and downlink data (programs) to and fro from the satellite. Once the program is uplinked to the satellite it can be viewed in any part of the country using the transmitter and receiver unit (at home, DTH). The program is downlinked at a T.V tower unit, then the different frequency is embedded for different programs (for DD News= 224.5MHz) in the form of electromagnetic waves. These waves are then transmitted in the air through an antenna. Now the same frequency is identified by the T.V receiver, it decodes it and we can see the desired program.
Have you ever noticed the direction of your DTH antenna?
- Once I was standing on the terrace, I observed that all the antenna of DTH is pointing towards the same direction. I was amazed. That dish antenna points towards the satellite of the country from where it can receive the signals (Radio frequency). In India, every dish antenna points towards South-East.
We cannot solve the problems with the same thinking we used when we created them – ALBERT EINSTEIN

Along with the undeniable natural beauty, the Kashmir valley has developed a reputation for adventurous activities like trekking, hiking, and river rafting. Kashmir has maintained its charm, allowing us to time-travel into beautiful destinations which make one forget about the stress and worries of life. The hikes in Kashmir offer adventurers to go on a self-discovery trip through nature's lap over the mountains while taking in the breathtaking scenery that surrounds them on their journey. In addition to the hikes, there are many thrilling adventure activities, like rock climbing, rope climbing, etc. Trekking across the region of mountains and lakes will allow you to experience living in the "Paradise on Earth," and you wouldn't want to return to your regular life after that.
The following are some of the finest hiking destinations in Kashmir:
#1: Kashmir Great Lakes Trek: You will be transported to a heavenly and unseen aspect of Kashmir on the Kashmir Great Lakes Trek. In addition to three high-altitude passes and five river valley crossings, this is the only trip in the Himalayas that includes seven alpine lakes, each of which is a stunning shade of green, blue, or turquoise. The extravagance is limitless and breathtakingly stunning every day: infinite blue sky, a larger-than-life backdrop of the Rocky Mountains, colourful meadows overflowing with wildflowers, river crossings are just a few examples of what you will encounter during the trek.

#5: Kolahoi Base Camp Trek: The Kolahoi Base Camp trek in Kashmir has been famous since the early 1900s and has been a goal for many seasoned hikers from across the world. While Srinagar serves as the beginning point for the trip, it is in Aru Valley that the actual hiking begins. The Kolahoi Base Camp Trek is a gentle adventure that is ideal for novices and families with children. The breathtaking sight of the peaks rising into the sky on the horizon of the Pirpanjal and Karakoram ranges is certainly worth capturing. It is considered to be one of the most popular treks in the Kashmir valley.

The Pitru Paksha starts after the Full Moon day, and this day marks the beginning of the waning phase of the Lunar cycle. This event is roughly of 15-day period, and is of great significance. From this day, rituals like Tarpan or Tarpanam and Shradh are carried out to pay respects to dead relatives and ancestors.
It is believed that from the very first day till the last day, the unhappy souls of the deceased return to the Earth to see their family members. So, in order to ensure that the dead attain Moksha, i.e. to get liberation, family members of these souls quench their thirst and satisfy their hunger by performing the Pind Daan, which includes offering food consisting of cooked rice and black sesame seeds. The literal meaning of Pind Daan is the act of satisfying those who no longer exist physically.
For fifteen days, prayers are offered in temples and rituals are performed to help the souls get free from the cycle of birth, life, and death, and attain salvation.
At the same time, the Pitru Paksha is also an important period for people with Pitru Dosha, which means the curse imposed by the ancestors. Hence, in order to ask forgiveness, people perform Shradh rituals and offer food to the crows, who are considered as living beings that represent the dead. It is believed, if the crow eats the offered food, the ancestors are happy and pleased. But, if the crow doesn't eat the offered food and flies away, the ancestors are not happy.
The event of Pitru Paksha is widely observed by Hindus from all over the world, and they perform prayers and rituals in order to gain their ancestors blessings.
At the heart of Bangalore city, a large 300-acre space of lush greenery and heritage stands as a symbol of the city's past, present, and future. Cubbon Park is every child's favourite park, every Bangalorean's haven of fresh air, and altogether, the city's pride.
It stands testament to the past, in terms of the diversity of flora it houses. Bangalore traffic in the recent past has grown into a menace, but the stretch between MG Road and Cubbon Park is always a pleasurable place to stop and wait for the signal to turn green. The gust of wind that blows here, and the smell of mud, coupled with floral scents instantly transports citizens to Old Bangalore, where the weather was fine, and the trees loomed over roads with thick canopies that did not even allow rainwater to penetrate. Cubbon Park is also a historical site, and one of the few remaining monuments of colonial heritage in Central Bangalore. It houses many statues and among them, the most famous is that of Queen Victoria, which faces the St. Mark's Square.

At present, Cubbon Park is known for the cultural hub that it is. It houses Jawahar Bal Bhavan, which is a large theatre that hosts film festivals through the year. Festivals, poetry open mics, and other such shows are conducted on the lawns every Sunday. A small stream runs through the park, where boat rides are held occasionally when the water level is high enough. There is a children's park on one corner, and a government-maintained aquarium, two-storeys tall, with exotic fish.
The Park has been renamed many times in the past. It was originally named Meade's Park, after Sir John Meade, the acting commissioner of Mysore in 1870. It was later changed to Cubbon Park after Sir Mark Cubbon, who was the longest-serving commissioner of the Mysore state. In 1927, the park was renamed after the Mysore Maharaja Sri Krishna Wodeyar, to celebrate his silver jubilee, since the park was developed during the reign of his ancestors. Even though it is officially named Sri Chamrajendra Park, it is still known as Cubbon Park all over the city. In fact, Bangalore was alluded the sobriquet of 'Garden City' because of the rich botanical diversity of this park.

In many parts of the country, governments have renamed structures, places, and cities to remove traces of colonialism. But, in a city like Bangalore, there is too much evidence of the British rule. Many of the most prominent attractions of the city are known by their British identities despite the change in name. Even the city's name continues to be Bangalore, despite having been changed to Bengaluru. Last year, the British era and its achievements were celebrated in Cubbon Park when Sir Mark Cubbon's statue was moved from the grounds of the Karnataka High Court and placed in the Park.
