WHY DO SNAKES HISS?

Snakes hiss primarily as a defense mechanism. Here's why they do it:

1. Warning signal: The hiss is meant to intimidate or scare off potential threats without resorting to a physical confrontation. 

2. Territorial behavior: Some snakes may hiss to assert dominance over a space, especially if they feel cornered.

3. No vocal cords needed: Snakes don’t have vocal cords. Instead, they produce the hissing sound by forcibly exhaling air through their glottis, which vibrates a small piece of cartilage to create that distinctive sound.

4. Camouflage enhancer: In some cases, hissing can mimic other sounds in nature (like a predator's growl or a larger animal's presence), adding a psychological layer to their defense.

Pine snake 

The pine snake (Pituophis melanoleucus) is known to have one of the loudest and most intense hisses among snakes. It's so powerful that it can sound like a high-pressure release of steam or even mimic the growl of a larger animal.

What makes it interesting is that the pine snake has a special flap of tissue in its glottis that enhances the sound, almost like a reed in a wind instrument. This allows it to amplify and control the pitch of its hiss—pretty sophisticated for a creature without vocal cords!

Other loud hissers include:

Bullsnakes (closely related to pine snakes)

Cobras (they also spread their hoods for extra drama)

Rattlesnakes (hiss along with their rattle for double threat effect)

How do snakes hiss?

Snakes hiss by forcibly exhaling air through their glottis, a small opening in the throat located just behind the tongue. Here's a step-by-step of how it works:

1. Air expelled from lungs: The snake forcefully pushes air out of its single functional lung (most snakes have just one main lung).

2. Glottis involvement: The air passes through the glottis, a slit-like structure in the windpipe.

3. Cartilage vibration: Inside the glottis, there's a small piece of cartilage that can vibrate as air rushes through, much like a reed in a wind instrument. This produces the hissing sound.

4. Mouth often closed: Unlike other animals that might open their mouths wide to vocalise, snakes usually hiss with their mouth closed or just slightly open.

5. Modulation: Some snakes, like the pine snake, can even modulate the sound to make it louder or change pitch, depending on the situation.

It’s all breath and no vocal cords—just clever use of air and anatomy.

The Spearhead of Indian Pace Attack

JASPRIT BUMRAH 

Jasprit Bumrah is a name that has redefined fast bowling in Indian cricket. Known for his unique action, lethal yorkers, and calm demeanor, Bumrah has emerged as one of the most dependable and feared bowlers in international cricket.

Born on December 6, 1993, in Ahmedabad, Gujarat, Bumrah’s journey to the top has been nothing short of inspiring. He made his debut for India in January 2016 during an ODI series against Australia. From there, he quickly rose through the ranks, making his Test debut in 2018 against South Africa.

Humble Beginnings: Bumrah’s Family Background

Jasprit Bumrah’s success story is rooted in a tale of resilience and determination. He was born into a middle-class Sikh family. His father, Jasbir Singh Bumrah, passed away when Jasprit was just seven years old, leaving his mother, Daljit Bumrah, to raise him and his sister alone. Daljit, a school principal, supported the family single-handedly and played a crucial role in Bumrah’s disciplined upbringing.

Despite financial constraints, his mother never let anything come between Jasprit and his dream of playing cricket. Her sacrifices and strength have been a major source of inspiration for him. Even today, Bumrah remains grounded and credits his mother for shaping his journey.

Rise to Stardom: What sets Bumrah apart is his ability to bowl consistently at high speeds with pinpoint accuracy. His unorthodox action initially raised eyebrows, but it has since become his biggest strength. Bumrah’s trademark toe-crushing yorkers, especially in the death overs, have won India many close matches. His variations and deceptive slower balls make him a complete package, especially in limited-overs cricket.

In Test cricket, Bumrah has proven that he is much more than a white-ball specialist. He has delivered match-winning performances in challenging overseas conditions, including memorable spells in England, Australia, and South Africa. His contribution was instrumental in India’s historic Test series wins in Australia in 2018–19 and 2020–21.

Record-Breaking Achievements

Bumrah's career has been full of remarkable milestones:

First Asian bowler to take five-wicket hauls in South Africa, England, and Australia in the same year (2018)

Fastest Indian pacer to reach 100 Test wickets

Best bowling figures by an Indian pacer in a World Cup match

Most wickets for India in a debut calendar year in ODIs (2016)

Only bowler to bowl 10 maiden overs in a World Cup match (2023)

Fastest Indian to 50 T20I wickets

Top performer in the ICC World Test Championship (2021–2023)

These achievements reflect not just his skill but his consistency and dedication to the game.

Calm Under Pressure: 

Bumrah’s temperament is another standout feature. He rarely shows emotion on the field, instead focusing on outsmarting the batter with skill and strategy. Even under pressure, he remains composed, making him a leader in the bowling unit.

Despite battling injuries at times, Bumrah has always made strong comebacks. His recent performances after returning from a long injury layoff have shown that he continues to be a force to reckon with. 

Jasprit Bumrah is married to Sanjana Ganesan. They tied the knot on March 15, 2021, in a private ceremony held in Goa. Sanjana Ganesan is a well-known sports presenter and a formal model from Pune, Maharashtra. She has hosted various sports events, including the Indian Premier League, IPL and Cricket World Cups.

They have a son named Angad.

In a country traditionally known for its spinners, Jasprit Bumrah has brought about a fast-bowling revolution. With many more years of cricket ahead of him, he is poised to leave an enduring legacy. His story—rising from humble beginnings to becoming a world-class bowler—is an inspiration to young athletes everywhere.

HOW DO INSECTS LIKE MOSQUITOES WALK ON WATER?

Insects like mosquitoes can walk (or more commonly, stand) on water due to the following reasons:

1. Surface Tension: Water molecules are strongly attracted to each other, especially at the surface. This creates a sort of "film" at the surface that resists external force—called surface tension. Small, lightweight insects don't exert enough force to break through this tension.

2. Hydrophobic Legs: Mosquitoes and other water-walking insects have hydrophobic (water-repellent) legs. Their legs are covered with microscopic hairs and waxy substances that repel water, helping them stay on top without sinking.

3. Weight Distribution: They have long, spread-out legs that distribute their tiny body weight over a wider area. This reduces pressure on any single point on the water surface.

So, they're not really walking in the usual sense—they're kind of “floating” on water.

Scientist who discovered neutral particle in an atom

JAMES CHADWICK

 

Neutrons, along with protons, are subatomic particles found inside the nucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge, with slightly more mass than positively-charged protons.

Pioneering British physicist James Chadwick discovered the neutron in 1932. His work not only expanded our understanding of the atomic structure, but also laid the groundwork for the development of nuclear physics and the atomic age. Chadwick’s discovery changed the way scientists viewed the nucleus of an atom, leading to revolutionary advances in energy production and atomic weaponry.

Born on October 20, 1891, in Bollington, Cheshire, England, Chadwick showed early academic promise. He attended the University of Manchester, where he studied physics under Ernest Rutherford, a mentor who had a profound influence on his career.

Rutherford’s research on atomic structure inspired Chadwick’s curiosity about the fundamental building blocks of matter.

After completing his studies in Manchester, Chadwick worked with prominent scientists, including Niels Bohr and Otto Hahn. Itwas during his time at the Cavendish Laboratory in Cambridge that Chadwick made his groundbreaking discovery. 

In 1932, he discovered the neutron by bombarding beryllium with alpha particles, resulting in the emission of highly energetic, uncharged particles. This neutral particle, which Chadwick identified as the neutron, was crucial in explaining the stability of atomic nuclei and provided a missing piece in the puzzle of atomic structure. 

Chadwick’s discovery of the neutron revolutionised the understanding of the atom. Before his work, scientists had identified protons and electrons, but they had not fully understood the role of neutral particles in the nucleus. 

Chadwick’s neutron theory allowed for a more complete model of the atom and paved the way for the development of nuclear reactors and weapons. 

In recognition of his monumental achievement, Chadwick was awarded the Nobel Prize in Physics in 1935. He continued to make significant contributions to nuclear research throughout his career, including work on the Manhattan Project during World War II. 

He passed away on July 24, 1974, in Cambridge, England.
