Looking Glass Universe

Looking Glass Universe is made by Mithuna Yoganathan, who completed a PhD in theoretical physics at the University of Cambridge. The channel is mostly about physics, and in recent videos she has turned more towards artificial intelligence.

Her best known videos tackle quantum mechanics, one of the hardest parts of physics to picture. She explains ideas such as spin and the double slit experiment carefully, often correcting popular myths along the way. Some videos include experiments she has done at home. Others are more personal, about research life and why she made the choices she did.

Some highlights include:

She sets up the famous double slit experiment at home and shows what light really does when it passes through two narrow gaps.

A clear introduction to spin, a property of particles that has no everyday equivalent and underpins much of quantum physics.

She explains why she left quantum computing research, giving an honest view of what academic research is like.

The channel has around 470,000 subscribers.

Looking Glass Universe is a good fit for students taking physics or maths at A level who want to go deeper. Quantum mechanics underpins semiconductors, lasers and quantum computing, so these ideas matter in electronic engineering and physics research. The more personal videos also give a realistic picture of life as a researcher, which is useful for anyone weighing up a PhD or a career in science.
