Wilfrid Noel Bond

Wilfrid Noel Bond is a chemistry 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 Wilfrid Noel Bond rather than just read about it. In short: Wilfrid Noel Bond (27 December 1897 – 25 August 1937) was an English physicist and engineer known for his work in fluid mechanics. He received his Doctor of Science from the University of London, and was a lecturer at the University of Reading from 1921 until his death.

Key takeaways

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

Reference excerpt

Wilfrid Noel Bond (27 December 1897 – 25 August 1937) was an English physicist and engineer known for his work in fluid mechanics. He received his Doctor of Science from the University of London, and was a lecturer at the University of Reading from 1921 until his death. The Bond number, used in fluid mechanics to characterize the shape of bubbles and drops, is named after him. Bond is also known for having described, in 1922, an improvement to the first fisheye lens setup, previously proposed by Robert W. Wood in 1908. Consisting of an hemispherical lens glass in a pinhole setup, it offered a much simpler and portable setup than its predecessor (which relied on a rectilinear lens installed inside a sealed tank of water) and reduced exposure times. The focal length depended on the refractive index and radius of the hemispherical lens, and the maximum aperture was approximately f/50; it was not corrected for chromatic aberration and projected a curved field onto a flat plate. Bond noted the new lens could be used to record cloud cover or lightning strikes at a given location.

Worked examples

Example 1 — a first encounter with Wilfrid Noel Bond

Start with the simplest possible case. Write down what Wilfrid Noel Bond claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Wilfrid Noel Bond 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 Wilfrid Noel Bond 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 Wilfrid Noel Bond

In research: Wilfrid Noel Bond appears in chemistry 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 Wilfrid Noel Bond 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: Wilfrid Noel Bond is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1897 births, 1937 deaths, 20th-century English engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Wilfrid Noel Bond 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.
