In last a few decades, there has been discovery and synthesis of a new class of materials that has astonishing properties but that could not be fully explained by the laws of classical physics. These properties can only be explained by quantum mechanics.

The Border Between Classical and Quantum Worlds: When Does Physics Go Quantum?
The value of this constant is very small = 6.626 x 10−34 J⋅s. At the time, no one fully understood the significance of this extremely small constant, but later we learned that it is this constant that sets the boundary between classical and quantum mechanics. In other words, this seemingly insignificant constant, with the dimension of energy x time, determines whether we need classical physics or quantum mechanics to describe a system.
New Breakthrough on Solar Wind Unveiled by India’s Mars Orbiter Mission (MOM)!
You may wonder that based on their limited observation, in the early days, people thought the Sun had an atmosphere, like Earth, experiencing seasons and even forming clouds. These clouds were thought to be responsible for the dark spots observed on the Sun’s surface (now the same is known the sunspot, a dark spot appears on the sun’s surface due to low temperature region).

Quantum confinement effect: controlled dance of electrons at microscopic level
Every solid material is made up of atoms and atoms have electrons. The arrangement of electrons in a material determines the properties of the material. In bulk materials (when the size of the material is big enough, let’s say more than 100 nm), the electrons are free to move in all the three dimensions (similar to us, as we also live in 3D) and at this level classical physics can explain all the behaviour of the materials. However, if we reduce the size of the material to microscopic scale, where electron movement is restricted at least in once dimension, the properties of the material change dramatically
The Pauli Effect: A Nightmare for Experimental Physicists
One of the most famous stories of the Pauli effect occurred in 1950 at Princeton University. A complex device suddenly broke down for no apparent reason. Scientists at the lab later discovered that Pauli had just come into town! This incident further cemented the myth.
Chandrayaan-3 Offers Groundbreaking Findings on Water Ice Retention on the Moon
ChaSTE measurements have indicated that there is an impact of local topography on the temperature. The lunar surface temperatures show a significant spatial variability at metre scales at high latitudes, unlike at the equatorial regions, indicating towards the possible presence of widespread water-ice within the shallow subsurface of , even at high latitudes.
The Moon’s Magnetic Mystery: Chandrayaan-2 Just Changed Everything We Knew
A new study based on radio signal analysis of the Chandrayaan-2 (CH-2) orbiter, has yielded surprising information regarding the Moon’s ionosphere. The study reveals that the moon’s ionosphere exhibits unexpectedly high electron densities when it enters the Earth’s geomagnetic tail, which could be explained only by the presence of a lunar crustal magnetic field.
A Private Spacecraft (Blue Ghost) Landed Successfully on the Moon for the First Time in Human History: The Next Chapter in Lunar Exploration
Firefly Aerospace, an American private aerospace firm founded in 2017, has made a remarkable achievement by successfully landing a spacecraft called ‘Blue ghost’ on the moon for the first time in human history.
