நாம் வாழும் இந்த உலகம் நம்பமுடியாத பல அதிசயங்களும், மர்மங்களும் நிறைந்தது. இந்த மர்மங்களைத் தேடிச்சென்றால் நாம் முடிவிலா ஒரு பயணத்தில் மாட்டிக் கொள்வோம். மர்மங்கள் மீது அ
Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound. The basis for an understanding of sound, music and hearing is known as Physics of waves. A sound wave is a pattern of disturbance caused by the movement of energy traveling through a medium, such as air, water, or any other liquid or solid matter. Sound waves are longitudinal waves
Modern computer technology is extremely sophisticated, and with the advent of quantum computing, it’s likely to become more so. With these more powerful machines, we’ll be able to perform large-scale simulations of more complex physical systems, including, possibly, complete living organisms, maybe even humans. But why stop there?
The idea isn’t as crazy as it sounds. A pair of philosophers recently argued that if we accept the even
Semiconductors made a strong way into display applications with the integration of LEDs in the early 2000s, allowing development of thinner and brighter electronic systems, and opening the way to a real display revolution. From traditional tube televisions to projectors, plasma screens to LCD and now O-LEDs, the consumer market has seen all manner of screen formats, definitions, and materials. As the smartphone, tablet, and high-def TV markets have exploded, t

Our expanding universe is filled with as many mysteries as we humans can imagine. These unexplored frontiers have beckoned the curious scientist for centuries, and mankind’s library of knowledge has increased because of it. But our knowledge is far from complete. Advances in space flight have spurred numerous discoveries; it can be expected that greatest ones will hinge on man’s ability to master rocketry’s te
Science is based on the measurement of physical quantities and reconciling them with theoretical formulations. Some of the major unsolved problems in physics are theoretical. Existing theories seem incapable of explaining certain observed phenomena or experimental results. In many cases, there are difficulties in creating experiments to test proposed theories, such as String Theory, or investigate some phenomena in greater detail, like the disappearance of ele
அண்டவெளியில் பூமியைத் தவிர மற்ற கிரகங்களில் உயிரினங்கள் வாழ்கிறார்களா இல்லையா என்பது பற்றிய ஆராய்ச்சிகள் நீண்ட காலமாக நடந்து வருகிறது. வேற்றுக்கிரகவாசிகள் இருக்கிறார்
If you are interested in the smallest things known to scientists, there’s something you should know. They are extraordinarily ill-behaved. But that’s to be expected. Their home is the quantum world. These subatomic bits of matter don’t follow the same rules as objects that we can see, feel or hold. These entities are ghostly and strange. Sometimes, they behave like clumps of matter. But in experiments, particles in the subatomic world sometim

A battery is a very important modern equipment. From the television remote control to the most expensive electric cars, these batteries are what keep them going. While batteries have been improving in recent times, at their core today’s batteries still operate on the same basic electrochemical principles developed in the 18th and 19th centuries. Some physicists are now wondering whether quantum phenomena may revolutionize conventional battery chemistry a
Time travel is a widely recognized concept in philosophy and fiction. The development of General Relativity was significant as it provided the theoretical backbone for how time travel could be conceived in scientific terms. This book covers a variety of topics including: the history of time travel in fiction, the fundamental scientific concepts of time the speculations of Einstein, Stephan Hawking, Richard Feynman and much more. This book explores the fascinat

Our universe is unimaginably big. Hundreds of billions, if not trillions, of galaxies spin through space, each containing billions or trillions of stars. Some researchers studying models of the universe speculate that the universe's diameter could be 7 billion light-years across. Others think it could be infinite but is it all that's out there? Science fiction loves the idea of a parallel universe, and the thought that we might be living just one of an infinit

Science is a beautiful gift to humanity. It can tell us what is true over mere assumptions by validating the theories with practical experiments have often led to important discoveries that eventually helped the mankind to live better life. Sometimes though, scientists in their quest for knowledge end up conducting experiments that are not only unethical but equally disturbing. The world has witnessed many of such spine- chilling and weird experiments that wen
The world's longest-lasting light bulb has been burning for nearly 120 years. The Livermore Centennial Light Bulb in Livermore, California, was installed in 1901, according to Guinness World Records, which recognizes it as the world's longest-burning light bulb. The hand-blown bulb was made by the Shelby Electric Company in Ohio in the late 1890s and donated to Livermore's fire department in 1901.This book describes the various lists of the Wonders of the worl
