Reference excerpt

Rudolf Zahradník (20 October 1928 – 31 October 2020) was a Czech chemist in the field of quantum chemistry and molecular spectroscopy. He held research positions at the Institute of Occupational Medicine and went on to serve as the first director of the J Heyrovsky Institute of Physical Chemistry, president of the Czech Academy of Sciences and chairman of the Learned Society of the Czech Republic, after the Velvet Revolution. During the 1980s, he taught future German leader Angela Merkel, who was then on an internship in Czechoslovakia. He held a doctorate from the University of Chemistry and Technology, Prague.

Early life and career Zahradník was born in Bratislava (then in Czechoslovakia, now in Slovakia) on 20 October 1928. He was a member of the Junák scout movement and decided to study chemistry when he read an article on invisible ink at grammar school. He graduated from the University of Chemistry and Technology, Prague in 1952, one of his teachers there was Jaroslav Koutecký. Four years later he obtained a Ph.D. in chemistry from the same university. Having previously been considered a bad influence on his students, Zahradník was able to obtain a research position after the Khrushchev Thaw relaxed Soviet restrictions on Czechoslovakia. He studied the relations between chemical structure and biological activity at the Institute of Occupational Medicine and theory of chemical reactivity and molecular spectroscopy at the Institute of Physical Chemistry of the Czechoslovak Academy of Sciences before being awarded a Doctor of Science degree by them in 1967. In 1959, Zahradník joined the faculty of Natural Sciences at Charles University and in 1961 served as a head of the Applied Quantum Chemistry Group at the Institute of Physical Chemistry, Czechoslovak Academy of Sciences. In the 1980s he taught Angela Merkel while she was on an internship in Czechoslovakia several times. They stayed in contact and she also visited him on his ninetieth birthday.

Career after the Velvet Revolution Between 1990 and 1993 Zahradník served as the first director of the J Heyrovsky Institute of Physical Chemistry before joining Clarkson University. During this period he has been described as "pushing forward the frontiers of quantum chemistry" and helped to bring young chemists into the field. From 1993 to 2001 he was president of the Czech Academy of Sciences and in 1994 became founding chairman of the Learned Society of the Czech Republic, holding the post until 1997. He was awarded the Czech Republic's Medal of Merit in 1998 and the Austrian Decoration for Science and Art in 1999. Zahradník was a recipient of a doctorate honoris causa from the TU Dresden and University of Fribourg (both in 1993), and from the University of Pardubice and Georgetown University in 1994 and 1996 respectively. He was also honored with doctorate honoris causa degrees from Charles and Clarkson universities in 1998. He published more than 350 papers and 10 books especially on quantum chemistry problems. He died on 31 October 2020.

Worked examples

Example 1 — a first encounter with Rudolf Zahradník

Start with the simplest possible case. Write down what Rudolf Zahradník 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 Rudolf Zahradník 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 Rudolf Zahradník 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 Rudolf Zahradník

In research: Rudolf Zahradník 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 Rudolf Zahradník 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: Rudolf Zahradník is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2020 deaths, Academic staff of Charles University, so understanding it makes those chapters shorter.
In everyday life: Look for Rudolf Zahradník 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.
