The second law of thermodynamics, part 1
A reversible Carnot engine operating between two given temperatures is the most efficient engine possible
Using the Michelson interferometer to detect gravitational waves
The Michelson interferometer is what rests in the heart of LIGO, that detected the gravitational waves for the first time. Here's how it works.
The first law of thermodynamics
According to the first law of thermodynamics, work spends energy and gives rise to heat.
The zeroth law of thermodynamics and basic definitions
If two systems are each separately in thermal equilibrium with a third, then all three systems are in thermal equilibrium with one another.
Newton's third law
Forces always come in pairs with every action cancelled by an equal and opposite reaction.

The theorising and discovery of black holes: the 2020 Physics Nobel
With increasing evidence being gathered about their existence, the 2020 physics Nobel finally recognised work done on black holes—but too late for Hawking.
Topological phases and transitions: the 2016 Nobel prize in physics
The 2016 Nobel prize in physics was awarded for work on topology in condensed matter physics. What exactly does it all mean? Physics Capsule explains.
LIGO detects gravitational waves
LIGO made the first direct detection of gravitational waves. What is LIGO, what are gravitational waves and why does this matter? Physics Capsule explains.
Why the BICEP2 results are important to physicists, part 2
How physicists use BICEP2, a telescope in the remote South Pole, to study polarisation of CMBR; and how some believe it should be verified first.
Why the BICEP2 results are important to physicists, part 1
Has the hunt for primordial B-modes in the far corners of our universe finally given us a proper reason to celebrate?

Reaffirming our support for LGBT+ people
Scientists identifying as LGBT+ have long shaped our view of the world. We support gender identities and believe they have no bearing on the science we do.
Series 2 of the Physics Capsule podcast is here
After a long gap necessitated in part by the COVID-19 pandemic, our editors are back to host the second series of our well-loved podcast.
Welcome to a new, learn-centric online magazine
Here are some things we have lined up for 2015, a few small changes, some radical ones, all targeted to making Physics Capsule even better than before.
