Pressure points The Institute of Physics says that recent errors in A-level physics unfairly perpetuate the myth that physics is a difficult subject. (Courtesy: shutterstock/monkey business images) ...
The New Scientist Book Club made a jump backwards through time for our latest read, Alex Foster’s Circular Motion, moving from the millennia-ahead future of Adam Roberts’s Lake of Darkness to a world ...
Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.
The interactive activity on this page is designed to visualise the states of matter and what happens when substances change state. You can use it to help your revision. There are three main states of ...
Top A* grades at A level in Wales have risen in the second "normal" exam year since pandemic disruption. More than one in 10 results achieved the gold star, but numbers taking A levels this summer are ...
Abstract: Video Motion Magnification (VMM) aims to reveal subtle and imperceptible motion information of objects in the macroscopic world. Prior methods directly model the motion field from the ...
The Future Circular Collider is profiling itself as the next flagship project at CERN. Its ambitious program would be a unique opportunity to fuel the field of high-energy physics for several decades ...
Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very ...
Zero-point motion capture: Ultrashort, high-intensity X-ray laser pulses trigger controlled explosions of molecules, making it possible to capture high-resolution images of molecular structures.
Recently, text-to-motion models have opened new possibilities for creating realistic human motion with greater efficiency and flexibility. However, aligning motion generation with event-level textual ...
Physicists have, for the first time, shown that even a single photon obeys one of nature’s strictest rules: conservation of angular momentum. Achieved only once in a billion attempts, this needle-in-a ...
