The document discusses the challenges that Indian students face in learning English for technical subjects like engineering, mathematics, and physics when studying independently without teachers or courses. It provides examples of scientific formulas and expressions that are difficult for ESL students to read aloud correctly in English due to unfamiliar mathematical symbols and operators. The author argues that the teaching of English for science and technology needs to account for the specific needs of Indian students and improve syllabus design, teaching methods, materials, and training for teachers to better equip them for scientific English.
