Uwe Mèffert

Uwe Mèffert is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Uwe Mèffert rather than just read about it. In short: Uwe Mèffert (28 November 1939 – 30 April 2022) was a German puzzle designer and inventor. He manufactured and sold mechanical puzzles in the style of Rubik's Cube since the 'cube craze' of the 1980s.

Key takeaways

  • Uwe Mèffert belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Uwe Mèffert to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Uwe Mèffert from memory before moving on to harder problems.

Reference excerpt

Uwe Mèffert (28 November 1939 – 30 April 2022) was a German puzzle designer and inventor. He manufactured and sold mechanical puzzles in the style of Rubik's Cube since the 'cube craze' of the 1980s. His first design was the Pyraminx – which he had developed before the original Rubik's Cube was invented. He created his own puzzle company and helped bring to market the Megaminx, Skewb, Skewb Diamond and many other puzzles.

Puzzle history

Invention of the Pyraminx In the early 1970s, Mèffert was interested in whether pyramids, cubes and other shapes might influence one's health and bio-energy flows. Mèffert constructed balsa wood polyhedra and found the gentle stroking of the apexes of the various shapes had a gentle massaging and stimulating influence and instilled a sense of peace, relaxation, and calm. After playing around with this idea for a while, he cut the solids into symmetric slices and attached them with rubber bands to a center ball. With the aid of his brother (an engineer), he was able to develop a simple mechanism that allowed the parts to move relative to each other. He made a few such devices and found them soothing to play with and helpful for meditation:

"I made five basic polygon objects, a tetrahedron, icosahedron, dodecahedron, etc, out of balsa wood, by cutting pieces and connecting them with some rubber bands and hooks. They didn’t have any colours because they were not toys. They were just things that I could use for several days and see if the different shapes had an effect on the human body." He did not think anyone else would be interested in the idea, and put the shapes away and forgot about them until Ernő Rubik's Cube became a worldwide sensation in the early 1980s. Mèffert's friends persuaded him to travel to Hong Kong in early 1981, where he met Dennis Ting Hok-shou of the Hong Kong Toys Association. Ting selected the pyramid puzzle and helped Mèffert produce an acrylic prototype. After meeting with Japanese toy companies, Tomy Toys agreed to market the brainteaser. The resulting puzzle, the Pyraminx, sold more than 10 million units that year, and 90 million within three years.

Puzzle company Uwe Mèffert became deeply involved in the production and marketing end of his Pyraminx, and came into contact with other inventors, and decided it would be a good idea to help manufacture and market their puzzle ideas. Mèffert established his own company in Hong Kong: Meffert’s Puzzles & Games. Mèffert bought the patent rights for the dodecahedron puzzle, and released it under the name of the Megaminx. Similarly he produced the first Skewb (invented by Tony Durham). Since that time, Mèffert and his associates have created more than 350 rotating mechanical puzzles and modifications. Mèffert has produced puzzle designs by Tony Fisher, including the Golden Cube, and Oskar van Deventer, including the Gear Cube. More recently he licensed and re-released designs from other manufacturers, such as Dogic. Mèffert also created his own version of sudoku. In addition to the standard sudoku rules, the two major diagonals must also contain the numerals from 1 to 9. Additionally, a Chinese magic square is hidden somewhere in the solution. He named this puzzle Kokonotsu, Japanese for nine.

Biography

Mèffert was born in Wernigerode in the Harz Mountains of Germany on 28 November 1939. Mèffert was the son of Otto Oscar Wilhelm Rudolph Mèffert and Emmy Johanna Frieda Von-Vorkauf. He was educated in Heidelberg, Germany, Geelong, Australia, and Bern, Switzerland. He resided in Hong Kong since the early 1980s, as well as spending much time in Australasia researching human and animal nutrition. He was married to Jing Mèffert; they have three children: Michelle, Andrew and Ulrich, and at least two grandchildren. Mèffert died 30 April 2022 due to complications while recovering from COVID-19.

Worked examples

Example 1 — a first encounter with Uwe Mèffert

Start with the simplest possible case. Write down what Uwe Mèffert 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 Uwe Mèffert 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 Uwe Mèffert 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 Uwe Mèffert

In research
Uwe Mèffert 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 Uwe Mèffert 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
Uwe Mèffert is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 2022 deaths, 20th-century German designers, so understanding it makes those chapters shorter.
In everyday life
Look for Uwe Mèffert 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.
