Lenard (crater)

Lenard (crater) 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 Lenard (crater) rather than just read about it. In short: Lenard is the former name of a lunar impact crater located on the lunar far side near the northern pole. The crater forms some of the wall of the crater Hermite, and is located North of the craters Lovelace and Froelich.

Key takeaways

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

Reference excerpt

Lenard is the former name of a lunar impact crater located on the lunar far side near the northern pole. The crater forms some of the wall of the crater Hermite, and is located North of the craters Lovelace and Froelich. Lenard was named after German physicist Philipp Lenard by the IAU, formally adopted as such in 2008. In 2020, upon learning of Lenard's support for the Nazi Party, Charles Wood, the chair of the Task Group for Lunar Nomenclature at the IAU, recommended to the IAU that the name "Lenard" be replaced. The name was dropped on August 12, 2020. Since then, this crater is officially unnamed.

See also Stark (crater), another lunar crater whose name was dropped in 2020 due to Nazi connections.

Worked examples

Example 1 — a first encounter with Lenard (crater)

Start with the simplest possible case. Write down what Lenard (crater) 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 Lenard (crater) 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 Lenard (crater) 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 Lenard (crater)

In research
Lenard (crater) 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 Lenard (crater) 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
Lenard (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics LQ01 quadrangle, Lunar crater stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Lenard (crater) 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.
