Schrödinger's Kittens and the Search for Reality

Schrödinger's Kittens and the Search for Reality 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 Schrödinger's Kittens and the Search for Reality rather than just read about it. In short: Schrödinger's Kittens and the Search for Reality is a 1995 book by John Gribbin, in which the author attempts to explain the mysteries of modern quantum mechanics in a popular-scientific way. It is a sequel to his earlier book, In Search of Schrödinger's Cat (1984).

Key takeaways

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

Reference excerpt

Schrödinger's Kittens and the Search for Reality is a 1995 book by John Gribbin, in which the author attempts to explain the mysteries of modern quantum mechanics in a popular-scientific way. It is a sequel to his earlier book, In Search of Schrödinger's Cat (1984). In his epilogue, Gribbin touches on what were then the most recent developments of string theory, and introduces the transactional interpretation of quantum mechanics as the new "mythology" of our time. His argument does not refute the theory, but demonstrates how all theories can be true and mythological (depending on one's perspective).

Worked examples

Example 1 — a first encounter with Schrödinger's Kittens and the Search for Reality

Start with the simplest possible case. Write down what Schrödinger's Kittens and the Search for Reality 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 Schrödinger's Kittens and the Search for Reality 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 Schrödinger's Kittens and the Search for Reality 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 Schrödinger's Kittens and the Search for Reality

In research: Schrödinger's Kittens and the Search for Reality 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 Schrödinger's Kittens and the Search for Reality 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: Schrödinger's Kittens and the Search for Reality is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1995 English-language non-fiction books, 1995 non-fiction books, Books by John Gribbin, so understanding it makes those chapters shorter.
In everyday life: Look for Schrödinger's Kittens and the Search for Reality 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.
