100 years ago: Mystery of magnetism

1. At a Glance

• The article is a "100 years ago" archival reprint from The Hindu (dated 17 Sept 1926 issue, republished 17 Sept 2026), reporting Prof. C.V. Raman's Calcutta research on magnetic anisotropy of liquid molecules [1].
• Significance for UPSC: illustrates pre-Independence Indian scientific achievement, and links to Raman's broader career culminating in the 1928 discovery of the Raman Effect and the 1930 Nobel Prize in Physics — the first Indian/Asian science Nobel laureate [2][3].
• Tests both history of science (GS-I/Art & Culture) and ability to connect an obscure primary-source snippet to well-known static facts.

2. Why in the News

• The Hindu's "100 Years Ago" column reprinted its original 17 September 1926 report on Raman's magnetism research, appearing in the 17 September 2026 print edition [1].
• Otherwise a static/historical topic — no independent contemporary scientific trigger.

3. Background & Evolution

• 1926: Raman and associates in Calcutta demonstrate, using sensitive optical methods, that molecules of common liquids (e.g., paraffin) orient themselves in a strong magnetic field, aligning favoured molecular directions parallel to the field — establishing a link between magnetism and molecular chemical structure [1].
• This magneto-optic work fed into Raman's wider investigations of light scattering and molecular optics at the University of Calcutta through the 1920s [1].
• 28 February 1928: Raman (with K.S. Krishnan) discovers the Raman Effect — inelastic scattering of light — published as "A New Radiation" in the Indian Journal of Physics (founded by Raman in 1926) [1].
• 1930: Awarded the Nobel Prize in Physics "for his work on the scattering of light and for the discovery of the effect named after him" — first Indian Nobel laureate in the sciences [2][3].
• 1933: Moved to Bangalore as Head of Physics, Indian Institute of Science.
• 1934: Founded the Indian Academy of Sciences.
• 1948: Founded and directed the Raman Research Institute, Bangalore, after retiring from IISc [2].

5. Multi-Dimensional Analysis

• Historical: Represents the peak of indigenous Indian scientific research during the colonial period, predating major state-funded science institutions (CSIR founded 1942, DAE 1948).
• Scientific/Technological: The 1926 magnetism work used refined optical methods to probe molecular structure — an early example of structure-property correlation in physical chemistry, later feeding into spectroscopy as a diagnostic tool used across chemistry, materials science, and medicine.
• Ethical/Governance: Raman's establishment of independent institutions (Indian Academy of Sciences, Raman Research Institute) reflects early efforts at building self-reliant Indian scientific infrastructure outside colonial university control.
• Administrative: Demonstrates the role of universities (Calcutta, later IISc Bangalore) as the primary vehicles for scientific research in India before dedicated national labs existed.

6. Recent Developments (last 12-18 months)

• No new scientific development; sole "recent" event is the The Hindu's archival republication of the 1926 report in its 17 September 2026 print edition under the "100 Years Ago" feature [1].

7. Prelims Hooks

• The 1926 report on molecular magnetism was made in Calcutta, not Bangalore [1].
• Raman's associates demonstrated liquid molecules (e.g., paraffin) orient in a strong magnetic field [1].
• Raman founded the Indian Journal of Physics in 1926 [1].
• The Raman Effect was discovered on 28 February 1928, commemorated as National Science Day in India.
• Raman's Nobel-winning paper was titled "A New Radiation" [2].
• C.V. Raman won the Nobel Prize in Physics in 1930 — first Indian science Nobel laureate [2][3].
• Raman was born on 7 November 1888 in Tiruchirappalli, Tamil Nadu [2].
• Raman moved to Bangalore in 1933 to head Physics at IISc [2].
• He founded the Indian Academy of Sciences in 1934 [2].
• He founded the Raman Research Institute in 1948 after retiring from IISc [2].
• Raman's key collaborator in this era was K.S. Krishnan, later known for work on magnetic anisotropy of crystals [1].
• The Nobel citation recognized work on "scattering of light" and the effect named after him [3].

8. How a Magnet Twisting Molecules Pointed the Way to the Nobel

• The 1926 work was really about a method, not about magnets
• Nobody can see a molecule. Raman's group used light to find out how molecules in a liquid were sitting inside a strong magnet [1].
• The idea: shine light in, study the light that comes out, and work backwards to what the molecules are doing.

• Two years later he used that same habit of thought on scattered light, and found the Raman Effect [1][2]. The 1926 report is the method being tried out before the famous result.

• It was curiosity research with no use in sight at the time

• In 1926 there was no product and no customer. Paraffin lining up in a magnetic field answered a question, nothing more [1].

• Today the same light-scattering idea is a routine testing tool in chemistry and medicine. This is the standard argument for funding science that has no visible use yet — and this article is a clean example to quote for it.

• Useful exam point: the Nobel citation rewards scattering of light, not magnetism [3]. So the 1926 article is a step on the road, not the prize-winning work itself.

9. Two Names on the Paper, One Name on the Prize

• What actually happened
• The magnetism work of this period, and the 1928 discovery, were done by Raman together with K.S. Krishnan [1].

• The 1930 Nobel Prize in Physics was given to Raman alone [3]. The Nobel rules allow a physics prize to be shared by up to three people, so a share for Krishnan was possible.

• The fair counter-argument, stated honestly

• Raman built the laboratory, chose the problem, ran the research programme at Calcutta and founded the journal the result was published in [1][2]. The direction of the work was his.

• Krishnan was the junior partner in that programme. Prizes across the sciences have almost always gone to the person who set the direction.

• Why an aspirant should still keep the point

• It gives you a real, non-copied line for any answer on "recognition in science": credit tends to collect at the top of a team.
• Krishnan's own later career answers the question in part — he went on to head the National Physical Laboratory (NPL), one of India's main national laboratories.
• Do not write this as a scandal. Write it as how scientific credit works.

10. One Science Nobel in 1930, and the Research Money Gap Since

• The plain fact to hold on to: Raman's 1930 award remains the only Nobel in the sciences won for work done in India [2][3]. That is ninety-six years. The interesting question for Mains is not who was great, but why the record stops there.
• India spends very little on research compared to its size
• GERD (Gross Expenditure on Research and Development — all money spent on research in a year, by government plus industry) was about 0.64% of GDP in 2020-21, and has stayed in the 0.6–0.7% range for years [4].
• This is below the world average and below China, South Korea and the United States [4].

• Basic science — the kind Raman did, with no product at the end — is the first thing cut when the total pot is small, because it cannot show a return.

• Indian industry barely funds research at all

• Government puts in roughly 64% of GERD; private industry only about 36% [5].
• In most advanced economies the position is reversed — companies fund most research, which frees public money for open-ended science.

• So in India the same government rupee has to pay for both applied work and curiosity work, and applied work wins.

• Why this connects back to the article: Raman's strength was a single university department with a clear head and a free hand [1]. That model does not grow by itself — it needs steady money and long time horizons, which a 0.6% share cannot give at national scale [4].

11. Who Should Pay for Curiosity-Driven Science in India Now

• ANRF must actually raise the private money it has promised
• The Anusandhan National Research Foundation (ANRF) — the new national body set up to fund and steer research — was created by the ANRF Act, 2023, which came into force on 5 February 2024 [4].
• It plans ₹50,000 crore over 2023-28, but only ₹14,000 crore comes from the Central Government. The rest must come from non-government sources [4].
• That is the weak joint: the same private sector that funds only 36% of research today is being asked to supply about 72% of ANRF's target [4][5].

• So the test of ANRF is not its launch, it is whether company money shows up. Watch that number, not the announcements.

• DST should report basic research separately in its statistics

• DST's R&D Statistics at a Glance reports totals by sector — government, industry, higher education [5].

• It does not let a reader see how much goes to open-ended science with no product in view. Without that line, nobody can say whether the Raman kind of work is being funded or quietly starved.

• Universities, not only national laboratories, need the research money

• Raman's Nobel work was done in a university department at Calcutta, before India had national laboratories at all [1][2].
• Today most public research money runs through national institutes, while ordinary state universities teach with almost no research budget.
• ANRF's stated aim of seeding research in universities and colleges is the right target — the thing to check is what share of its grants actually leaves the elite institutes [4].

12. Anchors for Answers

• Data: India's GERD was about 0.64% of GDP in 2020-21, and has stayed between 0.6% and 0.7% — below the global average and below China, South Korea and the US [4]
• Data: Government funds about 64% of India's R&D, private industry only about 36% [5]
• Data: One science Nobel for work done in India — Raman, Physics, 1930 [3]
• Law/Act: Anusandhan National Research Foundation Act, 2023 — in force 5 February 2024; ₹50,000 crore target for 2023-28, of which ₹14,000 crore from the Centre [4]
• Comparison: In most advanced economies business funds the larger share of research, the reverse of India's 64:36 split, which frees public money for basic science [5]
• Scheme/Institution: Raman Research Institute (1948) and Indian Academy of Sciences (1934) — scientist-founded bodies built outside state funding, a contrast with today's ANRF-led model [2]

15. Common Errors / Trap Areas

• Confusing the 1926 magnetism research (this article) with the 1928 Raman Effect discovery — they are distinct, though related, pieces of Raman's optical/molecular work.
• Assuming Raman's Nobel-winning work was done in Bangalore — it was actually done at the University of Calcutta; Bangalore/IISc came later (1933).
• Mixing up K.S. Krishnan (Raman's collaborator, later NPL Director) with other contemporaries like Meghnad Saha or S.N. Bose.
• Misdating National Science Day — it marks the 1928 discovery announcement, not the 1930 Nobel Prize year.
• Assuming the Indian Journal of Physics was a government/university body — it was founded by Raman himself as an independent scientific journal (1926) [1].
