Reference excerpt

The International Day for the Total Elimination of Nuclear Weapons, also known as Nuclear Weapons Elimination Day, is an international observance declared by the United Nations, held on 26 September every year. The day promotes the cause of nuclear disarmament. The observance was established in 2013.

History On 26 September 2013, the UN General Assembly held its first ever high-level meeting on nuclear disarmament; the resolution that convened the meeting stated that the UN was "Convinced that nuclear disarmament and the complete elimination of nuclear weapons are essential to remove the danger of nuclear war." On 3 December, the General Assembly passed resolution 68/32, affirming that the high-level meeting had endorsed the abolition of nuclear weapons, and declaring an annual International Day for the Total Elimination of Nuclear Weapons on the anniversary of the meeting. 26 September also corresponds with the anniversary of the 1983 Soviet nuclear false alarm incident, in which errors in a Soviet early warning system generated false reports of incoming ICBMs. However, the resolution declaring the observance did not make explicit reference to this co-occurrence. In March 2014, the Inter-Parliamentary Union passed a resolution calling on parliamentarians to "promote and commemorate" Nuclear Weapon Elimination Day and to work towards the abolition of nuclear weapons worldwide. The first observance took place in September 2014. In May 2018, following up on the 2013 high-level meeting and in accordance with resolution 68/32, the UN held the High-Level Conference on Nuclear Disarmament. NGOs and academics, as well as politicians from member states, were invited to participate. For the 2019 Nuclear Weapons Elimination Day, a ceremony was held at UN Headquarters in which 12 states signed and 5 ratified the Treaty on the Prohibition of Nuclear Weapons, which had been finalised in 2017. The treaty came into force in 2021. On the 2023 Day, UN Secretary General António Guterres said that "geopolitical mistrust and competition" had raised the risk of nuclear conflict back to Cold War levels. He again reaffirmed the UN's "commitment to a world free of nuclear weapons". In the UK, a group of activists from the Campaign for Nuclear Disarmament were denied access to the US Air Force-operated base RAF Lakenheath, where they planned to carry out an "inspection". No US nuclear weapons were based in the UK as of 2023, but there was speculation at the time that they could at some point be returned to Lakenheath, where they had been stationed from 1954 to 2007. In Japan, a group of NGOs and the UN Information Office held a symposium on nuclear disarmament, joined by officials from the Foreign Ministry.

Worked examples

Example 1 — a first encounter with International Day for the Total Elimination of Nuclear Weapons

Start with the simplest possible case. Write down what International Day for the Total Elimination of Nuclear Weapons claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Day for the Total Elimination of Nuclear Weapons before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Day for the Total Elimination of Nuclear Weapons ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Day for the Total Elimination of Nuclear Weapons

In research: International Day for the Total Elimination of Nuclear Weapons appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses International Day for the Total Elimination of Nuclear Weapons in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: International Day for the Total Elimination of Nuclear Weapons is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anti–nuclear weapons movement, Recurring events established in 2013, September observances, so understanding it makes those chapters shorter.
In everyday life: Look for International Day for the Total Elimination of Nuclear Weapons outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
