Harold Furth

Harold Furth is a physics 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 Harold Furth rather than just read about it. In short: Harold Paul Furth (January 13, 1930 – February 21, 2002) was an Austrian-American physicist who was a pioneer in leading the American efforts to harness thermonuclear fusion for the generation of electricity. He died of a heart ailment on 21 February 2002.

Key takeaways

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

Reference excerpt

Harold Paul Furth (January 13, 1930 – February 21, 2002) was an Austrian-American physicist who was a pioneer in leading the American efforts to harness thermonuclear fusion for the generation of electricity. He died of a heart ailment on 21 February 2002.

Early life Furth emigrated to the United States in 1941. His father fled a POW camp during WWI, but returned to Vienna a few years later. In his later years, he ran a shoe-making business with his family. He also developed an interest for literature. In the summer of 1939, Harold's father had escaped to Switzerland. After studying at the French-speaking École Internationale in Geneva, Harold immigrated to New York City in 1941. He later graduated at the head of his class at The Hill School. He graduated from Harvard University with a bachelor's degree in 1951 and received his Ph.D. from Harvard in 1960. His PhD thesis is entitled Magnetic Analysis of K– Interactions in Emulsion Nuclei.

Career Furth worked at Lawrence Livermore National Laboratory from 1956 to 1967 before going in 1967 to Princeton Plasma Physics Laboratory (PPPL) where he would spend the rest of his career working in plasma physics and nuclear fusion. He was also a professor of astrophysics at Princeton University. In the late 1960s, Furth contributed some important theoretical work on resistive magnetohydrodynamics instabilities in a slightly resistive plasma. In 1981 Furth became the director at PPPL and led the laboratory until 1990 during record setting magnetic fusion energy experiments on the largest tokamak in the country, the Tokamak Fusion Test Reactor (TFTR).

Awards In 1983, Furth was awarded the James Clerk Maxwell Prize for Plasma Physics by the American Physical Society. In 1992, he was awarded the Delmer S. Fahrney Medal (now known as the Benjamin Franklin Medal in Physics) by the Franklin Institute. Furth was also a member of the National Academy of Sciences.

Worked examples

Example 1 — a first encounter with Harold Furth

Start with the simplest possible case. Write down what Harold Furth 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 Harold Furth 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 Harold Furth 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 Harold Furth

In research
Harold Furth 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 Harold Furth 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
Harold Furth is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 births, 2002 deaths, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Harold Furth 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.
