1. At a Glance

The Hindu's "Daily Quiz" is a recurring general-knowledge feature; today's edition (6 Aug 2026, Chennai print edition, p.22) marks the 81st anniversary of the atomic bombings of Hiroshima and Nagasaki [1].
Topical hook for UPSC: nuclear weapons history recurs in Prelims (World History, disarmament) and Mains GS-I/GS-II (WWII, nuclear non-proliferation) [1][2].
Tsutomu Yamaguchi, featured as the quiz's "visual question" subject, is UPSC-relevant as the only officially recognised double hibakusha — survivor of both bombings [1].
The quiz format itself demonstrates the value of daily current-affairs practice for Prelims factual recall.

The Hindu published its 6 August 2026 Daily Quiz built around the 81st anniversary (6 & 9 August 1945) of the Hiroshima and Nagasaki atomic bombings [1].
Anniversary coincides with recurring UN commemorations on nuclear disarmament, keeping the theme in current affairs annually [2].

6 August 1945: "Little Boy," a gun-type uranium bomb, dropped on Hiroshima from B-29 bomber Enola Gay (pilot Col. Paul Tibbets Jr.) at 8:15 AM [3].
9 August 1945: "Fat Man," an implosion-type plutonium bomb, dropped on Nagasaki from B-29 bomber Bockscar [3].
Bombings preceded Japan's surrender (15 August 1945), ending WWII [1][3].
Post-war, the events catalysed the global nuclear disarmament movement, later institutionalised via UN forums (NPT Review Conferences, disarmament resolutions) [2].

Item	Detail
Bomb on Hiroshima	"Little Boy" — gun-type, uranium-235, ~12.5 kilotons TNT equivalent [3]
Bomb on Nagasaki	"Fat Man" — implosion-type, plutonium-239 [3]
Delivery aircraft	Enola Gay (Hiroshima), Bockscar (Nagasaki) — both B-29 Superfortress bombers [3]
Casualties	Hiroshima: ~120,000 dead within first four days; Nagasaki: 75,000+ instant deaths; combined estimated ~250,000 immediate deaths, further ~200,000 later from radiation [2][3]
Term "Hibakusha"	Japanese term for atomic bomb survivors [1]
Notable hibakusha	Tsutomu Yamaguchi — unique as a confirmed survivor of both Hiroshima and Nagasaki bombings [1]
Fireball temperature	~4,000°C at Hiroshima detonation point [2]
Official flower of Hiroshima	Oleander — first plant to bloom on scorched earth post-bombing (per quiz question) [1]

Historical: Marks the only wartime use of nuclear weapons; central event in 20th-century military history and WWII endgame [1][3].
Geopolitical/Strategic: Catalysed the Cold War nuclear arms race and subsequent non-proliferation architecture (NPT 1968, IAEA) [2].
Ethical/Governance: Raises questions on just-war theory, proportionality of civilian targeting, and continuing global debate on nuclear disarmament led by UN [2].
Scientific/Technological: Demonstrated practical application of nuclear fission (uranium vs plutonium bomb designs), reshaping physics-policy interface [3].

UN continues annual commemorations and disarmament messaging around 6-9 August dates, reiterating "never again" appeals from hibakusha survivors at review conferences [2].
The Hindu's 6 August 2026 Daily Quiz revisited this history with a themed quiz, reflecting continued media/editorial focus on the anniversary each year [1].

Hiroshima bombed 6 August 1945; Nagasaki bombed 9 August 1945 — three days apart [1][3].
Bomb dropped on Hiroshima code-named "Little Boy"; on Nagasaki, "Fat Man" [3].
Little Boy was a uranium-235, gun-type bomb; Fat Man was a plutonium-239, implosion-type bomb [3].
Delivery aircraft: Enola Gay (Hiroshima) piloted by Col. Paul Tibbets Jr.; Bockscar (Nagasaki) [3].
"Hibakusha" = Japanese term for atomic bomb survivors [1].
Tsutomu Yamaguchi is the only officially recognised person to survive both atomic bombings (double hibakusha) [1].
Three additional Japanese cities were reportedly on the initial target shortlist besides Hiroshima and Nagasaki (per quiz) [1].
Estimated immediate deaths from both bombings combined: ~250,000; further ~200,000 died later from radiation effects [2].
Fireball temperature at Hiroshima detonation reached ~4,000°C [2].
Bombings directly preceded Japan's surrender, ending World War II in August 1945 [1][3].

GS-I: World History — events leading to end of WWII, causes and effects of the war.
GS-II: International Relations — global nuclear non-proliferation regime, UN's role in disarmament.
Possible question stems:
"Discuss the strategic and humanitarian consequences of the atomic bombings of Hiroshima and Nagasaki on the post-WWII global order." (GS-I)
"Examine the role of the United Nations in advancing the cause of nuclear disarmament since 1945." (GS-II)
"Nuclear weapons pose an existential ethical dilemma between deterrence and humanitarian catastrophe. Comment." (GS-IV)

Nuclear Non-Proliferation Treaty (NPT), 1968 — direct institutional response to the nuclear age ushered in by 1945 bombings.
India's nuclear doctrine and No-First-Use policy — comparative angle for GS-III/GS-II.
IAEA and global nuclear safeguards — international governance mechanism.
UN Conference on Disarmament — multilateral forum tracking this history.
Manhattan Project — scientific/administrative background to the bombs' development.
Cold War arms race — direct historical consequence.
Comprehensive Nuclear-Test-Ban Treaty (CTBT) — later disarmament milestone.

Confusing bomb names with aircraft names (Little Boy/Fat Man are bombs; Enola Gay/Bockscar are aircraft) [3].
Mixing up bomb types: Hiroshima bomb was uranium-based (gun-type), Nagasaki bomb was plutonium-based (implosion-type) — commonly reversed in error [3].
Assuming both bombings happened on the same day; they were three days apart (6 and 9 August) [1][3].
Misattributing Tsutomu Yamaguchi's significance — he is notable specifically as a double hibakusha, not merely a survivor [1].
