Periodic table of shapes

Periodic table of shapes is a mathematics 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 Periodic table of shapes rather than just read about it. In short: The periodic table of mathematical shapes is the popular name given to a project to classify Fano varieties. The project was devised by Professor Alessio Corti, from the Department of Mathematics at Imperial College London.

Key takeaways

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

Reference excerpt

The periodic table of mathematical shapes is the popular name given to a project to classify Fano varieties. The project was devised by Professor Alessio Corti, from the Department of Mathematics at Imperial College London. It aims to categorise all three-, four- and five-dimensional shapes into a single table, analogous to the periodic table of chemical elements. It is meant to hold the equations that describe each shape and, through this, mathematicians and other scientists expect to develop a better understanding of the shapes’ geometric properties and relations. The project has already won the Philip Leverhulme Prize—worth £70,000—from the Leverhulme Trust, and in 2019 a European Research Council grant. While it is estimated that 500 million shapes can be defined algebraically in four dimensions, they may be decomposable (in the sense of the minimal model program) into as few as a few thousand "building blocks".

Worked examples

Example 1 — a first encounter with Periodic table of shapes

Start with the simplest possible case. Write down what Periodic table of shapes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Periodic table of shapes 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 Periodic table of shapes 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 Periodic table of shapes

In research: Periodic table of shapes appears in mathematics 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 Periodic table of shapes 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: Periodic table of shapes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Algebraic geometry stubs, Geometric shapes, so understanding it makes those chapters shorter.
In everyday life: Look for Periodic table of shapes 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.
