Inventions & Inventors Quiz — 7 Free Questions

Question 1

Who demonstrated in 1968 a hand-held wooden box on two perpendicular wheels that rolled a pointer around a screen, part of a landmark public showing of on-screen windows, clickable links and video calling decades before any of them were common?

Question 2

Which Edinburgh obstetrician found in 1847, by sniffing bottles of trial chemicals with two friends after dinner, that inhaling one of them brought swift unconsciousness, and began using it to spare women the pain of childbirth?

Question 3

Who wrote in 1952 the first working 'compiler', a program that turns instructions written in something close to human language into the raw numeric code a machine runs, an idea colleagues at first dismissed as impossible?

Question 4

Who unveiled in 1804 a loom attachment that stored a fabric's pattern as a chain of stiff cards punched with holes, letting a single weaver produce figured silk that had needed a boy pulling threads by hand, an idea later borrowed for calculating machines?

Question 5

Which American spent years and his family's savings hunting for a way to stop natural rubber turning sticky in summer and brittle in winter, then stumbled on the answer around 1839 when a lump mixed with sulphur fell on a hot stove and charred like leather instead of melting?

Question 6

Which civilisation first used a magnetised needle to find direction, employing a lodestone 'south-pointer' for divination by about the 1st century and for sea navigation by the 11th, long before such devices appeared in Europe?

Question 7

Who applied in 1608 for a patent on a tube holding two glass lenses that made far-off objects look three or four times closer, a device that spread across Europe within months and was turned on the night sky the next year by an Italian?

About Inventions & Inventors

An invention is the moment a want becomes a working thing. Somebody is annoyed that letters take weeks, that light means a candle, that surgery means being held down, and after a long stretch of tinkering, borrowing and failing, an object exists that did not exist before, and daily life quietly reorganises itself around it. The popular picture of a lone genius and a flash of insight is mostly a myth. Real inventions tend to arrive from several directions at once, lean on a stack of earlier work, and only look inevitable in hindsight.

This quiz runs across the whole span of that effort: communication, from the telegraph and telephone to the transistor and the integrated circuit; power and transport, from the steam engine and the electric battery to the bicycle and the pneumatic tyre; medicine, from anaesthesia to antiseptics; and materials, from vulcanised rubber to the first fully synthetic plastic. It also steps outside the usual Western list to take in paper and the decimal system with its number zero, two inventions without which almost none of the rest could have been written down or calculated.

Two traps come with the territory, and the answers try to handle both honestly. The first is disputed priority. The telephone, the light bulb, the integrated circuit, the sewing machine and the air-filled tyre each had two or more people arriving at nearly the same place at nearly the same time, and the name history keeps is often the one who patented, published or promoted first, not the one who was strictly earliest. Where a claim is genuinely contested, the explanation says so and names the rival. The second trap is the lone-inventor myth: many of these breakthroughs were the work of teams, backers and assistants whose names were left off the patent, and the answers put some of them back.

Each question describes an invention and the story around it without naming the person, country or thing responsible, and gives you four choices. The explanation then fills in the date, how the thing actually worked, who came a close second, what made it finally practical, and what it changed. Where a freely licensed photograph exists that shows the object or the setting but not the inventor's face, it is shown with the question; where the object itself would give the game away, the question is left as text.

The reason an inventions quiz sticks in the memory is that every answer is something you can hold in your hand or picture on a bench: a stack of metal discs, a bamboo thread glowing in a glass bulb, a ball rolling in the tip of a pen. Learn who built the first of each, and who nearly beat them to it, and you are also learning the shape of how a whole field moved from impossible to ordinary. The wording is kept plain, and every claim has been checked against reliable sources.
