Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of massive objects. The main source of detecting gravitational waves are the mergers of binary systems consisting of black holes and neutron stars. Till now, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo detector have successfully identified gravitational waves.

Biomimicry is the practice of imitating biological systems and processes. So far, it has been a valuable approach in robotics. By copying animals’ designs, engineers have tried to replicate billions of years of evolution. It has resulted in highly efficient and adaptable designs that nature has already passed on to. For instance, energy-efficient walking patterns inspired by animal gaits or bio inspired vision systems or lizard inspired four-legged robot.

Lately, there has been growing interest in creating brain-inspired hardware for enhancing efficiency of AI models. Conventional hardware architectures are specialized in three specific tasks, which are: Researches across the globe, however, are exploring the possibility of combining these functionalities into a single device. They aim to mimic the parallel and distributed nature of the human brain.

Researchers at Japan have discovered some new information about why all amino acids found on Earth are in a specific shape called “left-handed” or “L-form.” The team studied amino acids found in a meteorite called the Murchison meteorite. They also used computer simulations based on physics to understand how this shape came about.

The End of Faith: Religion, Terror, and the Future of Reason is a brilliant piece written by Sam Harris in 2004. Samuel Benjamin Harris (1967) is an American philosopher, neuroscientist, and an author. This book presents a stark difference between “faith” and “reason”. A profound stuff that is needed to be heard. Similar motif was also seen in Richard Dawkins’ famous book, The God Delusion. Why do religious ideas often look up to a unique level of respect? These ideas, are also exempted from scrutiny in many societies. While other…

In this post, we will be covering the second segment of Schrödinger’s famous book, What Is Life? with Mind and Matter. We have already talked about the first portion – What Is Life? Now, here, we will be focusing on Mind and Matter. (If you haven’t read, I’d recommend to go through the previous post – What Is Life? by Erwin Schrödinger. It will help in better understanding of his ideas. Thanks 🙂 In this series of the lectures, Schrödinger has tried to blend physics, evolutionary theory, and philosophy.

Erwin Schrödinger (1887-1961) was one of the renowned physicists and pioneer of quantum mechanics. He also had a deep interest in philosophy and metaphysics. What Is Life? with Mind and Matter by Erwin Schrödinger is a series of lectures. The lectures were delivered by him in 1943 and 1956 at Trinity College, Dublin. First part of the book explores the topic – What is life? The book on the same was first published in 1944. While the latter part is all about, Mind and Matter, the book on the same…

Juno is the famous space probe sent by NASA to study Jupiter. It was launched in 2011 and reached the gas giant planet in 2016. Instead of orbiting around the equator like previous missions, Juno entered a path that takes it over Jupiter’s poles. After its arrival, the space probe has been gyrating the planet in a specific orbit. With the help of special instruments on board, Juno is constantly collecting information from Jupiter’s environment. The main aim of the expedition, is to gather accurate data about the planet’s gravity…

Researchers at Stanford University have created a special kind of electronic skin that can sense things like heat and pressure and send signals to the brain. Electronic skin has been around for a while, but in the past, the devices used to convert these sensations into signals were bulky and inflexible. However, the new electronic skin is as soft and thin as real skin.

G.H. Hardy (1877-1947) was a prominent British mathematician who made significant contributions in various branches of mathematics, particularly in number theory and analysis. He collaborated with Indian mathematician Srinivasa Ramanujan and played an important role in recognizing and nurturing his exceptional talent. “A Mathematician’s Apology,” is a collection of his essays intended to peep into the mind and understand the perspective of a working mathematician.

Radiation belts are zones of charged particles, primarily electrons and protons, trapped by a planet’s magnetic field. They are typically found around planets with a significant magnetic field, such as Earth or Jupiter. These belts produce various radiations, including radio emissions, which can be detected and studied by radio telescopes.

Inspired by the natural design of our retinas, scientists at Penn State have created a sensor array using narrowband perovskite photodetectors to replicate the function of our cone cells. Cone cells in our eyes are responsible for color vision. And they are sensitive to red, green, and blue light wavelengths.

Friedrich Wilhelm Nietzsche (1844–1900) is known for his provocative and unconventional ideas. He often expressed views that were in direct opposition to prevailing religious, moral, and societal norms, particularly when it came to his criticisms of Christianity. He challenged many deeply ingrained beliefs and values of his time. His rejection of Christian morality and emphasis on individual will and self-assertion align with certain aspects of pagan thought and provide a philosophical foundation for those seeking to break free from Christian historical and social dominance.

When a star runs out of fuel, it eventually reaches the end of its life cycle and begin to expand. It swells to hundred or even a thousand times its original size. The process is called as a “red giant” phase. The progression enables the star’s outer layers to become less dense. Consequently, the star starts to swell outwards. In some cases, the star may expand so much that it engulfs any nearby planets.

Astronomers are always looking for exoplanets since it opens the door for better understanding of the formation and evolution of planetary systems beyond our own. With this aim in mind, NASA launched the Transiting Exoplanet Survey Satellite (TESS) in 2018. Primary parameter of this was to monitor the brightness of nearby stars. Till now, TESS has surveyed nearly 200,000 of the brightest stars near the sun. And so far, it has identified about 6,400 candidate exoplanets. To date, 330 of these candidates have been confirmed as exoplanets through follow-up observations…
