NASA’s Perseverance Took The Cutest Selfie With Ingenuity
NASA’s Curiosity rover has used some of our incredible selfies in its many years of service. Now that perseverance is also on Mars, NASA is…
The Fabled ‘Fuel-less’ EmDrive May Not Work, After All, Suggests New Studies
4 years ago, a radical new engine designed by NASA to create wave science science said it created thrust without using any fuel reported. The…
Difference between Balanced and Unbalanced Forces
Forces have a magnitude (strength) and a direction. Balanced forces are equal in size and opposite in direction. It implies the force which does not…
Anti-Matter From Beyond The Milky Way Proves 60-Year-Old Theory
A tiny electron anti-neutrino has traveled incredible cosmic distances at almost the speed of light, colliding with an electron on the ice of Antarctica. This…
Physicists Have Measured The Smallest Gravitational Field Yet
Scientists at the University of Vienna have now measured the smallest known gravitational field. As revealed in nature, the researchers measured the gravitational pull two…
Ferroelectricity – a spontaneous electric polarization
Ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field.…
Quantum tunneling – a quantum mechanical phenomenon
Tunneling is a quantum mechanical effect. A tunneling current occurs when electrons move through a barrier that they classically shouldn’t be able to move through.…
Magnetoresistance – the tendency of a material to change the value of its electrical resistance
Magnetoresistance, the change of a material’s resistivity with the application of a magnetic field, is a well-known phenomenon. Magnetoresistance is the tendency of a material…
Precision X-Rays Reveal Contents Of Sealed And Folded 17th Century Letters
Long before digital encryption, a wide range of methods used to hide the content of letters from Prize’s eyes. Centuries after the deaths of both…
Tunnel Magnetoresistance
Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field. Tunneling magnetoresistance (TMR)…
Memristor – a non-linear two-terminal electrical component
The term Memristor is a passive device that provides functional relation between charge and flux. It is a non-linear two-terminal electrical component relating to electric…
