I suspect it is time to explain "Umpire's Call" again. After the ball strikes the pad, what you see is a projection of where the ball might have been, it isn't the actual ball because that has met an obstruction. If more than 50% of the ball is projected to hit the stumps, you can be 100% sure it will. But if less than 50% of the ball is projected to hit the stumps, the current accuracy levels cannot state with 100% certainty that the ball would have hit the stumps. Hence, you go back to the Umpire's original decision because you cannot be certain enough to overturn his call. It is a very good and fair method. As cameras get better and the projected path more certain, we could reach a day when you can be certain that even if the projected path shows a ball merely clipping the stumps, it would in reality have hit them.
The 2023 chemistry #NobelPrize has been awarded to nanotechnology pioneers Moungi Bawendi, Louis Brus, and Alexei Ekimov for the discovery and synthesis of quantum dots. However, news of their win leaked about two hours before the official announcement.

Four engineers get into a car. The car won’t start.
Mechanical engineer: it’s a broken starter.
Electrical engineer: dead battery.
Chemical engineer: impurities in the gasoline.
IT engineer: hey guys, I have an idea how about we all get out of the car and get back in.
The 'eureka' moment of Archimedes is a famous story that illustrates how a sudden insight can solve a problem. According to the story, Archimedes was asked by King Hiero II of Syracuse to determine whether a crown made for him was pure gold or mixed with silver. Archimedes did not know how to measure the purity of gold without damaging the crown, so he was puzzled by this problem.
One day, he went to take a bath and noticed that the water level rose as he immersed himself in the tub. He realized that the amount of water displaced by his body was equal to the volume of his body, and that this principle could be applied to measure the volume of any irregular object. He then thought that by comparing the weight and volume of the crown with those of a pure gold sample, he could determine if the crown was adulterated or not. He was so excited by this discovery that he jumped out of the bath and ran naked through the streets, shouting “Eureka!” which means “I have found it!” in Greek.
This story is often used as an example of the eureka effect, which is the common human experience of suddenly understanding a previously incomprehensible problem or concept. The eureka effect is also known as the Aha! moment or insight. It involves a shift in perspective or a break in mental fixation that allows the solution to appear clear and obvious. The eureka effect is associated with positive emotions and a sense of confidence in the solution.
The eureka moment of Archimedes is also the basis of his famous principle, which states that when a body is immersed in a fluid, it experiences an upward force equal to the weight of the fluid displaced by the body. This principle explains how ships float, submarines dive, hot air balloons fly, and many other phenomena involving buoyancy.
Charles Darwin was elected a Fellow of the Royal Society in 1839 at the age of just 29. Here's Sir David Attenborough describing Darwin as "the founding father of scientific zoology and botany". See the full video here https://t.co/grMZ6Fhz1W #TheOriginOfSpecies#DarwinDay
In this experiment Dr Rob Thompson of @UniRdg_Met shows just how long it takes water to soak into parched ground, illustrating why heavy rainfall after a #drought can be dangerous and might lead to flashfloods.
