HERE’S THE REAL MEANING OF E = MC^2

Here’s a weird fact for you – a hydrogen atom has less mass than the combined mass of the proton and electron that make it up. Okay, it’s not just hydrogen – ALL elements on the periodic table weigh less than the sum of their parts. Here’s another mind-bender: if you have two objects are made up…

Battery can be recharged with carbon dioxide

The pH-gradient flow cell has two channels: one containing an aqueous solution sparged with carbon dioxide (low pH) and the other containing an aqueous solution sparged with ambient air (high pH). The pH gradient causes ions to flow across the membrane, creating a voltage difference between the two electrodes and causing electrons to flow along…

Physicists unveil new form of matter—time crystals

Following a blueprint created by UC Berkeley physicist Norman Yao, physicists at the University of Maryland made the first time crystal using a one-dimensional chain of ytterbium ions. Each ion behaves like an electron spin and exhibits long-range interactions indicated by the arrows. Credit: Chris Monroe, University of Maryland Normal crystals, likes diamond, are an…

UNIVERSE WITHOUT A BIG BANG- EINSTEIN’S LOST THEORY

  Einstein with Edwin Hubble, in 1931, at the Mount Wilson Observatory in California, looking through the lens of the 100-inch telescope through which Hubble discovered the expansion of the universe in 1929.

Quantum Theory 03

Discovery of Atomic Nucleus Ernest Rutherford discovered the nucleus in 1911. This discovery was based on Geiger Marsden experiment or commonly known as the gold foil experiment. He discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated. They deduced this by measuring how an alpha particle…

Physicists have found a metal that conducts electricity but not heat Defying one of the most fundamental laws of conductors.

Researchers have identified a metal that conducts electricity without conducting heat – an incredibly useful property that defies our current understanding of how conductors work. The metal contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is why things like motors…
