Otto F. Sankey

Otto F. Sankey 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 Otto F. Sankey rather than just read about it. In short: Otto Francis Sankey (11 January 1951 – 21 March 2020.) was an American physicist. He was Regents Professor at Arizona State University and a Fellow of the American Physical Society (elected in 2000).

Key takeaways

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

Reference excerpt

Otto Francis Sankey (11 January 1951 – 21 March 2020.) was an American physicist. He was Regents Professor at Arizona State University and a Fellow of the American Physical Society (elected in 2000).

Education Sankey received a B.S. in physics from the University of Missouri–St. Louis, and a PhD. in physics from Washington University in St. Louis under the supervision of Peter A. Fedders. After a postdoctoral appointment at the University of Illinois Urbana-Champaign, he spent the rest of his career at Arizona State University.

Career Sankey made important contributions to condensed matter theory, the most notable of which is the computer code FIREBALL, which enabled accurate and efficient simulation of complex materials. FIREBALL used local pseudoatomic orbitals as the basis set to solve the Kohn-Sham equations, which offered significant efficiencies in both computer memory and CPU use. The method has been generalized and extended into a number of DFT tight binding approaches and was a forerunner to the SIESTA program, particularly in its use of Sankey's compactly localized "fireball" orbitals. After his retirement, Sankey developed an interest in oncology and particularly the treatment of prostate cancer. He published the book Trouble with the Man Gland to explain the science of the disease and its treatment. Among many other original ideas, Sankey proposed a means of killing viruses through laser irradiation, essentially by exploding the capsid from a resonant coupling to the laser. His career was recognized by a Festschrift collection published in the journal Physica Status Solidi B. These papers included a Dedication in his honor and 13 scholarly papers contributed by peers celebrating his scientific achievements.

Death Sankey died of cancer in March 2020 at the age of 69. He is survived by his wife, Debbie; three daughters; and several grandchildren.

Worked examples

Example 1 — a first encounter with Otto F. Sankey

Start with the simplest possible case. Write down what Otto F. Sankey 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 Otto F. Sankey 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 Otto F. Sankey 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 Otto F. Sankey

In research: Otto F. Sankey 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 Otto F. Sankey 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: Otto F. Sankey is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, 2020 deaths, American condensed matter physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Otto F. Sankey 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.
