Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Quantum physics tells us about the properties and behaviors of atomic and subatomic particles. But scientists have long held the belief that the rules that govern the microscopic world should also be ...

Nice writing, Mr. Lee! I wish you had been my prof for my quantum chemistry class back in grad school. I've always imagined aromatic carbon compounds (like this phthalocyanine and like the bases that ...

The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...
