What is plank?   The plank exercise is a core strengthening exercise that involves holding a position similar to the top of a push-up, with the body straight and supported by the forearms and toes. The exercise is named after the plank, a long, flat piece of wood or other material used in construction. To perform a plank, you would start by lying face down on the ground or a mat, then place your forearms on the ground with your elbows directly below your shoulders. Next, lift your body up off the ground, supporting your weight on your forearms and toes, and hold the position for a set amount of time, typically between 30 seconds to several minutes, depending on your fitness level. Variations of plank exercise include side planks, reverse planks, and plank jacks. How does it benefit our health?    The plank exercise is a popular exercise for strengthening the muscles of the core, including the abdominals, obliques, and lower back. It can also help improve posture...

Pi  (π)  day  Happy Pi Day! Pi Day is celebrated on March 14th (3/14) every year to honor the mathematical constant pi (π), which represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number, which means it cannot be expressed as a finite decimal or fraction. Pi has been known for thousands of years, and its value has been calculated to trillions of digits. Although it is commonly approximated to 3.14, it is actually an infinitely long decimal number that never repeats. Pi is used in many areas of mathematics and science, including geometry, trigonometry, calculus, and physics. Pi Day is celebrated in many ways, such as by eating pie, participating in math competitions, and reciting the digits of pi. It is a fun and educational way to appreciate the beauty and complexity of mathematics.

  SVB Crisis: What led to fall of Silicon Valley Bank? On Friday, the banking regulators in the US shut down the "financial partner of the innovation economy", as the  Silicon Valley  Bank (SVB) called itself after it suffered a swift collapse. It has sent shock waves across the tech and banking industries. Undoubtedly, the bank catered to a very specific crowd of start-ups, venture capitalists (VCs) and tech firms, but before its collapse, SVB was the 16th biggest bank in the US. Moreover, it is the second bank, after Silvergate, that collapsed last week. It was followed by the US banking regulators shutting down the Signature Bank on Sunday, the third bank to close its doors in a week. Interestingly, it is the second-largest bank failure in the history of the US and the first such incident after the 2008 depression. Before this, Washington Mutual Bank had collapsed in September 2008. It had assets worth $307 billion and deposits of $188 billion. SVB, just before its col...

Optical fiber is a type of cable that is used to transmit digital information in the form of light pulses. It is made up of thin strands of glass or plastic that are designed to carry light over long distances. Here's how optical fiber works: Light source: A light source such as a laser diode or LED is used to generate a beam of light that is sent into the optical fiber. Core: The core of the fiber is a thin strand of glass or plastic that is designed to carry the light signal. The core is surrounded by a cladding layer that helps to reflect the light back into the core as it travels down the fiber. Total internal reflection: As the light signal travels down the core of the fiber, it undergoes a process called total internal reflection. This means that the light signal is reflected back into the core at the boundary between the core and the cladding layer. This reflection ensures that the light signal stays within the fiber and does not leak out. Data transmission: The light signal...

 Tomorrow Island (Big Diomede) and Yesterday Island (Little Diomede). The Diomede islands are just three miles apart but the bigger island is almost one day ahead of its smaller neighbour (21 hours) because they sit on either side of the International Date Line which passes through the Pacific Ocean and marks the boundary between one calendar day and the next. They sit in the Bering Strait between mainland Alaska and Siberia Big Diomede is located on the Russian side while Little Diomede is on the US side. The ice bridge that forms between the two islands in winter makes it possible, although illegal, to walk the short distance between them and 'travel through time'.
