Reference excerpt

Julian Phillip Heicklen (March 9, 1932 – March 11, 2022) was an American chemist and civil liberties activist.

Early life and education Heicklen was born on March 9, 1932, in Rochester, New York. Heicklen received a BA in chemical engineering from Cornell University in 1954. He received a PhD in chemistry from the University of Rochester in 1958.

Career After receiving his PhD, Heicklen moved to Los Angeles to work for a defense contractor. Heicklen became a professor at Pennsylvania State University in 1967. He was well liked by the students for his unorthodox style of instruction. To increase interest in his classes, he would hand out campaign buttons and appear in class wearing a cape. To demonstrate chemical reactions, he invited school gymnasts. He retired in 1992.

Activism While working in Los Angeles, Heicklen became active in the local chapter of the Congress of Racial Equality. He was involved in activism throughout his teaching career but became more active after his retirement. After he retired in the early 1990s, he openly smoked marijuana in public in State College, Pennsylvania, as a protest against marijuana laws and to intentionally be arrested, which happened about five times. He did not smoke marijuana recreationally and did so only as a protest. Heicklen was arrested multiple times by U.S. Department of Homeland Security federal police officers while distributing Fully Informed Jury Association (FIJA) literature at the United States District Court for the Southern District of New York. On May 25, 2010, he was arrested after refusing to stop handing out pamphlets about jury nullification at a U.S. District Courthouse in New York City, and was indicted for jury tampering. Because of previous failures to appear in court, he was remanded to Rikers Island until his June 8 arraignment. His arrest gained national attention over the following year due to the First Amendment implications of arresting a citizen for handing out educational pamphlets. Heicklen was arrested or fined multiple times related to distributing pamphlets on nullificiation. Heicklen wrote that during one arrest he chose to fall to the ground limp and silent; an ambulance was called and he signed his hospital release form as "John Galt." Another activist was arrested for filming on federal property without permission while recording Heicklen's November 9, 2009 arrest. Fellow nullification activists held a protest in his defense. On April 19, 2012, District Court Judge Kimba Wood granted Heicklen's Motion to Dismiss the Indictment as legally deficient.

Worked examples

Example 1 — a first encounter with Julian Heicklen

Start with the simplest possible case. Write down what Julian Heicklen 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 Julian Heicklen 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 Julian Heicklen 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 Julian Heicklen

In research: Julian Heicklen 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 Julian Heicklen 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: Julian Heicklen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2022 deaths, American chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Julian Heicklen 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.
