Hilgardia

Hilgardia is a biology 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 Hilgardia rather than just read about it. In short: Hilgardia was a peer-reviewed academic journal published by the California Agricultural Experiment Station, which was founded by the Agricultural Experiment Stations Act of 1887. The title honors Eugene W.

Key takeaways

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

Reference excerpt

Hilgardia was a peer-reviewed academic journal published by the California Agricultural Experiment Station, which was founded by the Agricultural Experiment Stations Act of 1887. The title honors Eugene W. Hilgard, who was from 1875 to 1904 Professor of Agricultural Chemistry at UC Berkeley and was also the California Agricultural Experiment Station's first Director. The journal, which was published from 1925 (volume 1) to 1995 (volume 62), published a total of 972 articles. The Hilgardia Project, launched in April 2011, has now made freely available all of the Hilgardia articles in online pdf format. Many of the articles, 71 of which deal with viticulture, are still of scientific and commercial interest. According to Janet White:

Although production ceased in 1995, Hilgardia editions include classic research that is still widely cited in scientific literature, and many are considered cornerstones of current agricultural, environmental and nutritional research.

Worked examples

Example 1 — a first encounter with Hilgardia

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

In research: Hilgardia appears in biology 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 Hilgardia 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: Hilgardia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic journals established in 1925, Agricultural journals, Agriculture stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Hilgardia 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.
