Timeline of Scientific Discoveries — Master Reference for Pakistani Competitive Exams
The chapter Timeline of Scientific Discoveries is one of the highest-yield General Knowledge / Everyday Science topics in Pakistan’s PPSC, FPSC, NTS, CSS, PMS, OTS, CTS, BPSC, KPPSC and SPSC exams. Almost every Junior Clerk, Tehsildar, Assistant, Sub-Inspector, Lecturer and BPS-14 to BPS-17 paper carries 3–6 MCQs from this chapter — and it is core CSS Screening MPT (General Science & Ability) content. This page consolidates 65 solved MCQs covering ancient milestones (wheel — Sumerians 3500 BCE, paper — Ts’ai Lun 105 CE, gunpowder — China 1232), the scientific revolution (Galileo’s telescope 1609, Newton’s laws 1687, Volta’s battery 1800), 19th–20th century classics (telegraph, telephone — Bell 1876, X-rays — Röntgen 1895, airplane — Wrights 1903, photoelectric effect — Einstein 1905, nuclear reactor — Fermi 1942, DNA — Watson & Crick 1953, Sputnik 1957, integrated circuit 1958, microprocessor 1971, WWW — Tim Berners-Lee 1989) and the most recent breakthroughs (graphene 2004, iPhone 2007, quantum supremacy 2019, CRISPR Nobel 2020, ChatGPT-Bing 2023). For wider context, see Wikipedia: Timeline of Scientific Discoveries and the official Nobel Prize Laureate List.

Exam tip: Memorise year + person + thing as a single chunk — Bell-1876-Telephone, Wrights-1903-Airplane, Röntgen-1895-X-rays, Watson-Crick-1953-DNA, Berners-Lee-1989-WWW. Examiners commonly substitute the wrong year (off by 5–10) or the wrong person (Tesla vs Edison). Locking the triple eliminates both traps.
