Jacob Barnett is a physicist working in one of the most abstract areas of modern science: quantum mechanics.

His academic work belongs to a world of concepts most people rarely encounter in everyday life - locality, pseudo-Hermitian physics, non-Hermitian systems, exceptional points, and the mathematical structure of quantum theory.

As a child and teenager, Jacob was often presented in the media as a prodigy. Stories focused on his age, his early university-level studies, and his reported progress through advanced mathematics and physics.

At the age of two, Jacob was diagnosed with autism. Early in life, his communication and development did not follow a typical pattern. To people around him, what was happening inside his mind was often difficult to understand.

A child may not respond in an expected way, but still be observing, processing, and building an inner map of the world.

A child may focus deeply on details that others overlook and that focus may be mistaken for disconnection instead of recognized as attention.

Jacob could spend hours focused on patterns. Light filtering through blinds, shadows shifting across the floor, the movement of dust motes in a sunbeam. To most therapists, this was stereotypy - self-stimulatory behaviour to be interrupted and redirected.

But what if it was a window into the way his mind processed information?

Books with complex geometric designs were left where he could find them. Puzzles, building blocks, and maps were brought into his play. Instead of being pulled away from his fixations, he was given ways to follow them - and what first looked like a limitation began to reveal itself as a path forward.

Social skills were the hardest piece. Jacob did not read faces or tone. He did not grasp playground politics. His family invited neighbourhood children over and engaged them in Jacob's interests: building huge structures with wooden blocks, mapping the backyard, creating mazes. Jacob was not trying to keep up with the other kids; they were joining him in his world. Communication happened naturally because there was something he wanted to share.

During evening walks, Jacob suddenly showed a deep interest in the stars. He became completely fascinated by them. 

And one day, he was taken to a planetarium.

At the end of a long and difficult lecture, the speaker asked the audience, “Does anyone know why the moons around Mars look like potatoes?”

Jacob immediately raised his hand:

The moons around Mars do not have enough mass and gravity to become round.

That moment changed everything for his family. They realized how different Jacob was from others. 
And when he was allowed to follow what brought him joy, the constant frustration eased - and communication began to appear.

He went to a public school. He would come home and curl up, he didn't play with his friends. By the time he turned ten, his mother decided to pull him out of school and began homeschooling without standard curricula and with letting him pursue what fascinated him.

Jacob tore through textbooks. He studied calculus, physics, astronomy. At nine, he began auditing university courses.

At twelve, he was formally enrolled at Indiana University - Purdue University Indianapolis, where he sat alongside students a decade older.

At thirteen, he published his first research paper with Yogesh Joglekar.

In his TEDxTeen talk, “Forget What You Know,” Jacob explained one of his central ideas in simple language:

“In order to succeed, you must think in your own creative way.”

He also said:

“Instead of being a student of that field, be the field.”

These sentences reveal a great deal about how he understood learning.

Jacob Barnett’s path continued into serious academic work. 

Mathematics and physics became serious fields of study, places where his way of thinking could develop.

At the age of sixteen, he completed the Perimeter Scholars International master's program at the Perimeter Institute.

At this Institute, he was mentored by Lee Smolin, a renowned theoretical physicist who helped guide him during his first serious steps in academic science.

“He’s done an excellent job at shaping me into a young scientist,” said Jacob in one of his interviews, “encouraging me to develop my own research tastes while answering questions and bringing me up to date on various physics topics.”

In 2023, his doctoral thesis, “Locality and Exceptional Points in Pseudo-Hermitian Physics,” was listed by the University of Waterloo.

Today, his academic profile places him in quantum mechanics research at the Basque Center for Applied Mathematics in Spain.

He taught a graduate-level math course there, and his lectures are available on YouTube.

In addition to his work in mathematical physics, Jacob also competed professionally in foosball. Ranked in the top 10 of the ITSF rankings in 2025, he competed internationally and won events in Europe and North America.
