Enriched uranium is uranium processed to increase the concentration of the fissile isotope uranium-235 (U-235) beyond its natural abundance of 0.7%. Fissile refers to a material—specifically a nuclide—that can undergo nuclear fission when it absorbs a low-energy (thermal) neutron. This property is crucial because only fissile materials can sustain a self-sustaining nuclear chain reaction with…

Four researchers from the Institute of Photonics at Leibniz University Hannover have created a new transmitter-receiver system for sending entangled photons through an optical fiber.

One of the most basic ideas in physics is that the different properties of mass – weight, inertia and gravitation – always stay the same in relation to each other. This is really important because if it wasn’t true, Albert Einstein’s theory of relativity would be wrong and we’d have to rewrite our physics textbooks.

The study of fluids and physics with buoyancy involves some important principles: buoyancy, fluid motion, fluid resistance, and a Reynolds number.

A group of scientists from Ohio University, Argonne National Laboratory, and the University of Illinois-Chicago, among others, led by Ohio University Professor of Physics, and Argonne National Laboratory scientist, Saw Wai Hla, have achieved a groundbreaking feat – capturing the world’s first X-ray signature of a single atom.

The energetic universe as seen with the eROSITA X-ray telescope

In the 1920s, Edwin Hubble made a groundbreaking discovery while observing distant galaxies: the universe is expanding. However, it wasn’t until 1998 that the observation of Type Ia supernovae led to the further discovery that the universe is not just expanding, but also experiencing accelerated expansion. Astrophysicist Joe Mohr from LMU explains that to account…

Have you ever experienced time slowing down or speeding up? A new study suggests that our moment-to-moment perception of time is not continuous but may stretch or shrink with each heartbeat.

Wavefunctions of the electron in a hydrogen atom at different energy levels

A recent study published in the journal Nature by researchers from the Weizmann Institute of Science introduces a new tool that makes use of the wave-particle duality of electrons.

Caltech engineers have discovered that Leonardo da Vinci’s understanding of gravity, although not entirely accurate, was ahead of his time by centuries.

Quantum computer modules being aligned so atoms can transfer between quantum computer microchips

Researchers have demonstrated for the first time that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking speed and accuracy.

In the early 1500’s, Leonardo da Vinci explored gravity as a form of acceleration and modelled the gravitational constant to around 97% accuracy.

Breakthrough! Scientists demonstrate that quantum bits can directly transfer between quantum computer microchips allowing chips to slot together like a jigsaw puzzle.
