The massive problem of trying to fully explain what mass actually is

21 June 2023

I can take it as a given that people have an intuition for the meaning of mass, but traditional explanations can feel unsatisfactory. Even the standard model doesn't give us all the answers, says Chanda Prescod-Weinstein


How can we prove the world is really quantum mechanical?

How can we prove the world is really quantum mechanical?

26 April 2023

A 2021 paper has got physicists discussing whether our inability to use classical physics to describe reality on a quantum scale is a human failing - and what proof is necessary to show that the world really is quantum mechanical, says Chanda Prescod-Weinstein

Why uncertainty is part of science - especially quantum mechanics

1 March 2023

Quantum mechanics had a disordered beginning in the 1920s, and is still developing today. Science is rarely a done deal, says Chanda Prescod-Weinstein

Why the most important topic in physics could be statistical mechanics

1 February 2023

Statistical mechanics helps relate the quantum world to objects that seem solid and not governed by the whims of observation, but there are still questions to be answered, says Chanda Prescod-Weinstein

Physicists should take time to ponder the strangest ideas

4 January 2023

There are other ways to explain wave-particle duality than Albert Einstein's, but we don't teach them. Excluding the conceptual challenges of quantum mechanics from the classroom limits our students, says Chanda Prescod-Weinstein

The blessing and the curse of the axion’s rise in US particle physics

23 November 2022

Since the Large Hadron Collider turned up nothing in its search for supersymmetry, physicists have turned their attention to the axion, says Chanda Prescod-Weinstein, a self-described superfan of this hypothetical particle

What does it mean when we say that space-time is expanding?

6 July 2022

When it comes to something as complex as space-time, intuition comes in different ways, depending on the level of science you have access to, writes Chanda Prescod-Weinstein

Why we can't always make sense of physics with words alone

8 June 2022

We physicists want to give everyone a feel for what we're learning, but the truth is that there is often no intuitive explanation for what our equations and their solutions are telling us, writes Chanda Prescod-Weinstein


Why I'm choosing dark matter over dark energy - for now at least

Why I'm choosing dark matter over dark energy - for now at least

13 April 2022

Dark matter is my focus these days, but the intractable problems of dark energy and cosmic acceleration are still on my mind, says Chanda Prescod-Weinstein
