Meet Ahmed El Ghandour. He may just be the most popular teacher in Egypt.

The self-confessed physics lover hosts a science series that has clocked up more than 19 million views on YouTube since its launch in 2014.

As Al Daheeh, an insecure nerd, he covers topics ranging from evolution to war and blockchain.

El Ghandour’s aim is to make science fun and accessible to millions. “I love all scientific subjects,” he says. “I can’t stick to learning only one.”
