Thomas Landauer

Thomas Landauer is a astronomy 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 Thomas Landauer rather than just read about it. In short: Thomas K. Landauer (April 25, 1932 – March 26, 2014) was a professor emeritus at the Department of Psychology of the University of Colorado.

Key takeaways

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

Reference excerpt

Thomas K. Landauer (April 25, 1932 – March 26, 2014) was a professor emeritus at the Department of Psychology of the University of Colorado. He received his doctorate in 1960 from Harvard University, and also held academic appointments at Harvard, Dartmouth College, Stanford University and Princeton University. During his 25-year tenure as Distinguished Member of Technical Staff at Bell Labs and its successors, where he was the manager of an information science and human-computer interaction research group, he was one of the pioneers of Latent semantic analysis. His publications include:

The Trouble with Computers, a controversial analysis of the productivity paradox of information technology. Psychology: A Brief Overview published in 1972. Handbook of Latent Semantic Analysis, co-edited with Danielle S. McNamara, Simon Dennis and Walter Kintsch in 2013. In 1998, Landauer became the founding president of Knowledge Analysis Technologies (KAT), founded to commercialize his work in automated essay scoring and related technologies, based on latent semantic analysis. KAT was acquired in 2004 by Pearson Education, where Landauer continued to serve as executive vice president until his death.

Worked examples

Example 1 — a first encounter with Thomas Landauer

Start with the simplest possible case. Write down what Thomas Landauer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Thomas Landauer 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 Thomas Landauer 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 Thomas Landauer

In research: Thomas Landauer appears in astronomy 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 Thomas Landauer 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: Thomas Landauer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2014 deaths, 20th-century American psychologists, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas Landauer 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.
