Infants experimentant amb un pèndol de Newton

A brief history of recreational physics

One way to stimulate interest in physics is to expose people to experiences that arouse their curiosity and lead them to seek explanations for phenomena.

Science anywhere and anyhow

Today, citizens interested in science have many ways to access it, from the classic formats of books and journals, to television and radio programmes, to social networks and other internet platforms.

Fighting gender bias at the speed of light

Full Professor of Physics Pas García takes a gendered approach to her field, which involves the diffraction and polarisation of light. She points out that women in physics represent only around 20–22% of researchers.

‘Tenet’ and the arrow of time

Could there be a universe where the laws of physics were different and there was no second law of thermodynamics? Christopher Nolan's film Tenet (2020) explores this new reality.

On the road to nuclear fusion energy

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.

Why does the fall speed of a body (attracted by gravity) not depend on its mass?

When a body descends in air or another fluid, what determines its acceleration is the gravitational force minus the friction, not its mass.

At their own pace

In resonance, the force transmitted to the object may be relatively small, but when it is transmitted with the right frequency, it oscillates with great amplitude.

Finding north

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.

Complex systems

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.

Vacuum-packed, please

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.
