Reference excerpt

James Michael O'Dwyer is an inventor who grew up in Muttaburra, Queensland, Australia, chiefly known for his Metal Storm weapon.

Biography O'Dwyer completed Year 12 education, then went on to be a manager at Woolworths before his inventions were able to provide an income. An American company, Breeze Technology Holdings, has the rights to one of his inventions – air-cooled sneakers.

Metal Storm

O'Dwyer spent 15 years developing a rapid-fire gun prototype called Metal Storm that uses stacked projectiles. Metal Storm can fire up to 1,000,000 rounds per minute, or 16,000 rounds per second, and was declared by Guinness World Records to be the world's most intelligent and fastest firearms. The technology was being commercialised by a company also called Metal Storm, but they requested their shares be suspended from trading on 20 July 2012 and later was placed into voluntary administration. In late 2015, DefendTex, an Australian-based defence R&D company, acquired the intellectual property, trademarks and other assets of Metal Storm.

Worked examples

Example 1 — a first encounter with J. Mike O'Dwyer

Start with the simplest possible case. Write down what J. Mike O'Dwyer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 J. Mike O'Dwyer 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 J. Mike O'Dwyer 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 J. Mike O'Dwyer

In research: J. Mike O'Dwyer appears in science 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 J. Mike O'Dwyer 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: J. Mike O'Dwyer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Australian inventors, Living people, Weapon designers, so understanding it makes those chapters shorter.
In everyday life: Look for J. Mike O'Dwyer 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.
