Nuclear fusion energy has great advantages. The latest discoveries in this field made by the National Ignition Facility in the United States have great scientific significance.
The purpose of this monograph is to introduce and promote recreational science and its uses to the general public. Deadline for submission (extended): 20 July 2023.
When a body descends in air or another fluid, what determines its acceleration is the gravitational force minus the friction, not its mass.
If we hang a magnet by a thread, it always aligns itself in the same direction, even if there is no other magnet nearby. This is a compass and responds to the Earth's magnetism.
The 2021 Nobel Prize in Physics has recognised the work in the study of complex systems in nature, but Ferran Martin looks at other complex systems in his particular look at this week's news.
In the 17th century, it was difficult to achieve and maintain a partial vacuum. In the 21st century, the challenge is to achieve an ultra-vacuum in the laboratory such as we could never have dreamed of.
Human eyes cannot perceive colours at night because cones, responsible for colour perception, are only activated under intense light conditions.
Ferrran Martin refers to Gravitational Wave Astronomy following the first observation of a binary system of a black hole and a neutron star.
For there to be sound, there must be a vibrating source, a transmitting medium that propagates the vibration at a certain speed, and a receiver that is set into vibration when the wave arrives.
There is no way to force a pendulum to oscillate at a different rhythm, determined exclusively by its length
