Tibees

Toby Hendy, known as Tibees, is an Australian science communicator who produces mathematics and physics content on YouTube under a low-energy, methodical style. Her channel launched around 2013 and has grown to several million subscribers. She holds a degree in physics and has discussed her own experiences with mathematics education in her videos. Her delivery is notably quieter and slower-paced than the majority of educational YouTube content, which has attracted viewers who prefer that format.

Her most widely viewed format involves working through university entrance exams from different countries — including papers from Cambridge, MIT, the IIT-JEE, and the Japanese national university entrance exam — explaining each problem step by step. These videos function as both exam preparation resources and comparative illustrations of how different educational systems approach mathematics. She also produces videos on the history of mathematics, individual mathematicians and physicists, and the philosophy of science.

Hendy's channel occupies a specific niche in math and science communication distinguished primarily by its presentation style rather than its topical coverage, which overlaps with other math-focused channels. Her publishing frequency is moderate rather than high. Her background in physics provides grounding for the technical content she covers, and her explanations are generally considered accurate by viewers with relevant academic backgrounds.
