Reference excerpt

Heinz Billing (7 April 1914 – 4 January 2017) was a German physicist and computer scientist, widely considered a pioneer in the construction of computer systems and computer data storage, who built a prototype laser interferometric gravitational wave detector.

Biography Billing was born in Salzwedel, in Saxony-Anhalt, Germany. After studying mathematics and physics in University of Göttingen he received his doctorate in 1938 in Munich at the age of 24. During the Second World War he worked in the Aerodynamics Research Institute in Göttingen. On 3 October 1943 he married Anneliese Oetker. Billing has three children: Heiner Erhard Billing (born 18 November 1944 in Salzwedel), Dorit Gerda Gronefeld Billing (born 27 June 1946 in Göttingen) and Arend Gerd Billing (born 19 September 1954 in Göttingen). He turned 100 in April 2014 and died on 4 January 2017 at the age of 102. Advanced LIGO detected the fourth gravitational wave event GW170104 on the same day.

Computer science Billing worked at the Aerodynamic Research Institute in Göttingen, where he developed a magnetic drum memory. According to Billing's memoirs, published by Genscher, Düsseldorf (1997), there was a meeting between Alan Turing and Konrad Zuse. It took place in Göttingen in 1947. The interrogation had the form of a colloquium. Participants were Womersley, Turing, Porter from England and a few German researchers like Zuse, Walther, and Billing. (For more details see Herbert Bruderer, Konrad Zuse und die Schweiz). After a brief stay at the University of Sydney, Billing returned to join the Max Planck Institute for Physics in 1951. From 1952 through 1961 the group under Billing's direction constructed a series of four digital computers: the G1, G2, G1a, and G3. He is the designer of the first German sequence-controlled electronic digital computer as well as of the first German stored-program electronic digital computer.

Gravitational wave detector After transistors had been firmly established, when microelectronics arrived, after scientific computers were slowly overshadowed by commercial applications and computers were mass-produced in factories, Heinz Billing left the computer field in which he had been a pioneer for nearly 30 years. In 1972, Billing returned to his original field of physics, at the Max Planck Institute's new location at Garching near Munich. Beginning in 1972, Heinz Billing became involved in gravitational physics, when he tried to verify the detection claims made by American physicist Joseph Weber. Weber's results were considered to be proven wrong by these experiments. In 1975, Billing acted on a proposal by Rainer Weiss from the Massachusetts Institute of technology (MIT) to use laser interferometry to detect gravitational waves. He and colleagues built a 3m prototype Michelson interferometer using optical delay lines. From 1980 onward Billing commissioned the development and construction in MPA in Garching of a laser interferometer with an arm length of 30m. The knowledge gained from this prototype was crucial to beginning the LIGO project.

Awards and honors In 1987, Heinz Billing received the Konrad Zuse Medal for the invention of magnetic drum storage. In 2015 he received the Order of Merit of the Federal Republic of Germany. In 1993, the annual Heinz Billing prize for "outstanding contributions to computational science" was established by the Max Planck Society in his honor, with a prize amount of 5,000 Euro.

Worked examples

Example 1 — a first encounter with Heinz Billing

Start with the simplest possible case. Write down what Heinz Billing 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 Heinz Billing 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 Heinz Billing 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 Heinz Billing

In research: Heinz Billing 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 Heinz Billing 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: Heinz Billing is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 2017 deaths, 20th-century German physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Heinz Billing 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.
