Little b (programming language)

Little b (programming language) is a computer 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 Little b (programming language) rather than just read about it. In short: Little b is a domain-specific programming language, more specifically, a modeling language, designed to build modular mathematical models of biological systems. It was designed and authored by Aneil Mallavarapu.

Key takeaways

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

Reference excerpt

Little b is a domain-specific programming language, more specifically, a modeling language, designed to build modular mathematical models of biological systems. It was designed and authored by Aneil Mallavarapu. Little b is being developed in the Virtual Cell Program at Harvard Medical School, headed by mathematician Jeremy Gunawardena. This language is based on Lisp and is meant to allow modular programming to model biological systems. It will allow more flexibility to facilitate rapid change that is required to accurately capture complex biological systems. The language draws on techniques from artificial intelligence and symbolic mathematics, and provides syntactic conveniences derived from object-oriented languages. The language was originally denoted with a lowercase b (distinguishing it from B, the predecessor to the widely used C programming language), but the name was eventually changed to "little b" to avoid confusion and to pay homage to Smalltalk.

Worked examples

Example 1 — a first encounter with Little b (programming language)

Start with the simplest possible case. Write down what Little b (programming language) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Little b (programming language) 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 Little b (programming language) 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 Little b (programming language)

In research: Little b (programming language) appears in computer 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 Little b (programming language) 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: Little b (programming language) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cross-platform free software, Dynamic programming languages, Dynamically typed programming languages, so understanding it makes those chapters shorter.
In everyday life: Look for Little b (programming language) 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.
