5 More Bengali Geniuses Who Built Your Modern World — and Got Erased

Support the channel - https://ko-fi.com/withronny Between 1850 and 1924, five men in Calcutta and Dhaka did the foundational work behind a mountain, a medicine industry, the global wireless network, and quantum physics itself — and almost none of them got the credit at the time. The name on the tallest mountain on Earth belongs to a man who never climbed it. The Nobel Prize for the wireless went to Italy. And a whole category of matter in the universe — the boson — is named after a man who couldn't get a four-page paper past a London journal. This is the story of Radhanath Sikdar, Prafulla Chandra Ray, Upendranath Brahmachari, Jagadish Chandra Bose, and Satyendra Nath Bose — proved paper by paper, with the receipts. Everything in this video is real and checkable: the survey manual that dropped Sikdar's name in its 1875 edition; Ray's 1896 mercurous-nitrite paper and the Bengal Chemical & Pharmaceutical Works (still running in 2026); Brahmachari's urea stibamine and his seven Nobel nominations in the now-public Nobel archive; - US Patent 755,840, J.C. Bose's galena crystal detector, filed 1901; and S.N. Bose's 1924 letter to Albert Einstein, published in - Zeitschrift für Physik, the paper the 2001 Nobel (Cornell, Wieman, Ketterle) was awarded for confirming. ⏱ Chapters 0:00 The letter to Einstein 2:52 Radhanath Sikdar — the man who measured Everest 7:53 Prafulla Chandra Ray — the chemist who built an industry 11:26 Upendranath Brahmachari — the cure with no first name 16:12 Jagadish Chandra Bose — the patent that predates radio 21:35 Satyendra Nath Bose — the particle named as a consolation prize 27:33 The receipts are still switched on Sources & receipts: US Patent 755,840 (USPTO) · Emerson, IEEE Trans.
