Reference excerpt

Julius Timoleon Ducatel (June 6, 1796 - April 23, 1849) was an American chemist.

Education and Paris years He was educated at St. Mary's College, and then became associated in business with his father, long the principal pharmacist in Baltimore. His experience in this direction developed a fondness for the study of the natural sciences, and he turned to Paris, where for several years he was occupied in this pursuit.

Academic career

Professorships and varied interests Soon after his return to Baltimore he became professor of natural philosophy in the Mechanics' institute, and later professor of chemistry and geology in the University of Maryland, Baltimore. His ability as a scientist and his success as a lecturer afterward led to his election to the chair of chemistry in the medical department of the university. From 1832 till 1841 he held appointments in connection with the State geological survey, at first in the preliminary work, and then as geologist. Meanwhile he had been made professor of chemistry, mineralogy, and geology in St. John's College, Annapolis, but he resigned both of these posts in 1839 in order to devote more time to his specialty of geology.

Geological exploration In 1843 he made a geological exploration of the upper Mississippi in connection with an expedition sent to that region, and in 1846 visited the Lake Superior district for persons interested in the industrial development of that country. He delivered an interesting series of lectures on his return, giving an account of his experiences.

Membership of scientific organisations, publications Ducatel was a member of scientific societies at home and abroad, and regularly contributed scientific articles to the Baltimore Times and the American Farmer. His principal work was a Manual of Toxicology (Baltimore, 1848).

Worked examples

Example 1 — a first encounter with Julius Timoleon Ducatel

Start with the simplest possible case. Write down what Julius Timoleon Ducatel 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 Julius Timoleon Ducatel 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 Julius Timoleon Ducatel 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 Julius Timoleon Ducatel

In research: Julius Timoleon Ducatel 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 Julius Timoleon Ducatel 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: Julius Timoleon Ducatel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1796 births, 1849 deaths, American chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Julius Timoleon Ducatel 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.
