Key takeaways

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

Reference excerpt

William Samuel Bialek (born 14 August 1960) is a theoretical biophysicist and a professor at Princeton University and The Graduate Center, CUNY. Much of his work, which has ranged over a wide variety of theoretical problems at the interface of physics and biology, centers around whether various functions of living beings are optimal, and (if so) whether a precise quantification of their performance approaches limits set by basic physical principles. Best known among these is an influential series of studies applying the principles of information theory to the analysis of the neural encoding of information in the nervous system, showing that aspects of brain function can be described as essentially optimal strategies for adapting to the complex dynamics of the world, making the most of the available signals in the face of fundamental physical constraints and limitations. Bialek received his AB (1979) and PhD (1983) degrees in Biophysics from the University of California, Berkeley. After postdoctoral appointments at the Rijksuniversiteit Groningen in the Netherlands and at the Kavli Institute for Theoretical Physics in Santa Barbara, he returned to Berkeley to join the faculty in 1986. In late 1990 he moved to the newly formed NEC Research Institute (now the NEC Laboratories) in Princeton. He is currently the John Archibald Wheeler/Battelle Professor in Physics at Princeton University, and a member of the multidisciplinary Lewis–Sigler Institute. In addition, he serves as Visiting Presidential Professor of Physics at CUNY Graduate Center. Bialek has made contributions to shaping the education of the next generation of scientists, such as organizing the Princeton Lectures on Biophysics, a series of workshops that provided many young physicists with an introduction to the challenges and opportunities at the interface with biology. The textbook he coauthored, Spikes: Exploring the neural code has also been similarly used by many young physics students as an introduction to neuroscience. He is currently involved in a major educational experiment at Princeton to create a truly integrated and mathematically sophisticated introduction to the natural sciences for first year college students. Most recently, he published Biophysics: Searching for Principles, a textbook based on his course for PhD students.

Honors

Bialek received the 2013 Swartz Prize for Theoretical and Computational Neuroscience from the Society for Neuroscience. A member of the National Academy of Sciences (US), he has also been honored for his teaching with the Phi Beta Kappa Prize and the President's Award for Distinguished Teaching at Princeton. In 2017, he won the Max Delbruck Prize, which is given by the Biological Division of the American Physical Society.

Worked examples

Example 1 — a first encounter with William Bialek

Start with the simplest possible case. Write down what William Bialek 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 William Bialek 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 William Bialek 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 William Bialek

In research: William Bialek 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 William Bialek 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: William Bialek is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, 21st-century American physicists, American theoretical physicists, so understanding it makes those chapters shorter.
In everyday life: Look for William Bialek 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.
