Man and the Planets

Man and the Planets 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 Man and the Planets rather than just read about it. In short: Man and the Planets: The Resources of the Solar System is a book written by Duncan Lunan. Contents Man and the Planets is a book published in 1983 which studies the resources of each planet in the Solar System.

Key takeaways

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

Reference excerpt

Man and the Planets: The Resources of the Solar System is a book written by Duncan Lunan.

Contents Man and the Planets is a book published in 1983 which studies the resources of each planet in the Solar System.

Reception Dave Langford reviewed Man and the Planets for White Dwarf #41, and stated that "Lunan's enthusiasm is infectious, his research exhaustive; he's absolutely committed to the Dream of Space and has no time for the many equally learned people who fear that the expense of opening up this new frontier would wreck our world economy long before producing tangible benefits."

Worked examples

Example 1 — a first encounter with Man and the Planets

Start with the simplest possible case. Write down what Man and the Planets 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 Man and the Planets 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 Man and the Planets 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 Man and the Planets

In research: Man and the Planets 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 Man and the Planets 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: Man and the Planets is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomy books, so understanding it makes those chapters shorter.
In everyday life: Look for Man and the Planets 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.
