When baller shine one side of ball, that side of ball become smooth and other side became rough side compared to shined side. When the baller bowls the ball, it go through to air and an air flow flows around ball’s surface. since the ball has one side of ball’s surface is shiny and smooth and the other side is rough, the smooth surface passes through the air more faster while the rough surfaces passes slowly because the surface friction. . According to burnuellie’s theory the flow with low velocity have high static pressure than flow with higher velocity .the ball trends to move towards to the smooth side of ball. This movement create ball swing and make unpredictable path towards to the wicket.
In the game of Cricket , Have you seen that bowlers shine one side of the ball before bowling? What’s the reason to shine only one side of the ball?
Did you know that Burmese pythons, one of the largest snake species in the world, can regenerate their organs? After a python ingests a prey, it might be as long as a year before its next meal. In the meantime, basically its entire digestive tract atrophies, out of having no work to do. But when the python gets its next meal, all those organs regenerate within two days of feeding and its major organs grow up to 140–200% of their previous sizes.
Ever wondered why cancer patients who undergo chemotherapy lose their hair? Chemotherapy drugs kill rapidly growing cancer cells but also affect normal fast growing cells in the hair roots, making hair strands more likely to break from their roots itself.
Have you ever wondered how dimples are formed? Dimples are formed due to a variation in the facial muscle known as Zygomaticus major. The defect pulls on the skin when the person smiles, causing the facial indentation.
Avocado contains Omega 3 monounsaturated fatty acids (MUFA) which can reduce LDL (Bad) Cholesterol and increase HDL (Good) Cholesterol in the blood. Also It contains lot of vitamins such as A,D &K. Anti-oxidants such as Vitamin E and C which protect against carcinogenic agents and improve health. Avocados are particularly rich in potassium, good food to lower risk of kidney failure and heart disease. So nutritionist recommend Avocado as a healthy food.
Even though Avocado is rich in fat,Nutritionists says it is good for health.Why is that?
Can you recall a time when you were yawning and a jet of saliva erupted from under your tongue? This happens because there is a pair of salivary glands located under your tongue that could get squeezed with activities like yawning.
Do you remember the time when your baby sister or brother was learning to talk? Although you wouldn’t have understood the baby talk, you and your parents must’ve responded in your own words. This response is what’s valuable for a baby to learn faster and smarter. Although this feedback process was long thought to be human-specific, researchers have discovered it in another animal: marmoset monkeys. Their studies have proved that monkey babies who are exposed to more of the parental feedback develop adult-sounding calls more rapidly, just like human babies learning to talk faster when they get more vocal responses from their adults.
If you are a cat lover who has pet cats at home or who could spend hours watching cat videos online, you would’ve noted that those little feline friends love to play with boxes. They could spend all day hiding in and popping out of boxes. This behaviour is explained researching the way they’ve hunted throughout their evolution. When cats hunt, they hide and ambush their prey. Since boxes are perfect hiding spots for cats to do so, they love to play with them.
The major causes for low platelet count of Dengue patients are inducing bone marrow suppression by the Dengue virus,destroying platelets by dengue infected vascular endothelial cells with the combination of platelets and destroying platelets by antibodies which produced to defend the body from dengue virus
Dengue patients are generally identified with low platelet count than usual.What is the reason for lower platelet count in Dengue fever?
Shell tube heat exchangers in large scale industrial heating and cooling systems use a counter current configuration to maximize efficiency. Isn’t it amazing to know that these systems were inspired by the innovative adaptation of penguin’s blood circulatory system! Can you remember once we told you, what makes penguins survive in very chilly climates is this distinctive blood flowing pattern? It is very much similar to the flow pattern in above heat exchangers.
World has come up with an extraordinarily creative novel solution for the air pollution problem. It is none other than AIR INK: World’s first ink made out of air pollution! This is produced with the aid of a device that captures soot particles and turns it into safe high quality ink. Who knew pollution could create art?
An alternative design strategy for a novel antireflective coating which could absorb more solar energy and boost the efficiency of solar cells has been invented! Can you believe that this design was inspired by the nanostructures found on moth’s eyes? Nocturnal moths navigate under the dim light of moon and stars, thanks to these eyes covered with anti-reflective micro sized lenses. These structures absorb almost all incident light, thus reducing reflection that predators would notice.
Gas bubbles that evolve when opening a soft drink bottle is CO2. Solubility of CO2 in liquid is higher when the liquid is cooler. So once the bottles are opened if we keep them in a refrigerator where temperature is lower than room temperature, can retain more gas itself making the drink fizzier.
We all have experienced that when soft drink bottles are opened, fizzy gas bubbles evolve from it. Once these bottles are opened it is recommended to store them inside a refrigerator because chilled soft drinks taste fizzier than the ones kept in room temperature. What is the reason behind this?
Air-conditioning uses a tremendous amount of energy, but a new group of designers think they can solve this problem by mimicking Mother Nature’s craftiness. Capturing the forces of nature displayed in tornadoes and whirlpools have been the inspiration to design novel fans. These fans are known to have lower turbulence and higher efficiency for cooling.
Have you figured out the precise pattern displayed by trees when their branches are formed? A main trunk will grow until it produces a branch, which creates two growth points. Then only one of the new stems branches into two, while the other one lies dormant. This pattern of branching is repeated for each of the new stems. This gives adequate time for a new shoot to be strong enough to support branching and to be stable.
Have you ever heard of a bizarre beast born with an air conditioner in its body itself? Saiga antelope who is now a critically endangered species, has a fabulous nose that works a bit like an air conditioner! In summer it cools the air before it hits the antelope’s lungs, and in winter it warms the inhaled air.
Even though common tent materials have minute pores, surface tension of water can bridge these gaps. Also during rainy conditions normally inside of the tent is warmer than the outside, and this can cause condensation of water droplets on its inner surface. By touching the tent material with the finger, we break the surface tension allowing the rain drops to drip through.
