Key takeaways

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

Reference excerpt

Jiří Drahoš (born 20 February 1949; Czech pronunciation: [ˈjɪr̝iː ˈdraɦoʃ]) is a Czech physical chemist and politician who has been the Senator of Prague 4 since October 2018. Previously, Drahoš served as President of the Czech Academy of Sciences from 2009 to 2017, and was a candidate in the 2018 Czech presidential election. Born in Český Těšín and raised in nearby Jablunkov, Drahoš studied physical chemistry at the University of Chemistry and Technology in Prague, and joined the Institute of Chemical Process Fundamentals of the Czechoslovak Academy of Sciences in 1973, which he later led from 1995 to 2003. In 2009, he was elected President of the Czech Academy of Sciences. His term as head of the academy ended on 24 March 2017. In March 2017, Drahoš announced his candidacy for President of the Czech Republic in the 2018 election. He ran on a moderate centrist platform, and is generally pro-European and supportive of NATO and Atlanticism. Drahoš lost the second round of the presidential election to his opponent President Miloš Zeman with 48.6% of the vote, but vowed to remain in public life. In October 2018, he stood for the Czech Senate in the Prague 4 district, winning the election outright in the first round with 52.65% of the vote. He is a member of the European Academy of Sciences and Arts.

Early life and career Jiří Drahoš was born on 20 February 1949 in Český Těšín to a Czech father originally from Skuteč in Vysočina, and a Polish mother from Jablunkov. He spent most of his childhood in Jablunkov, where his mother Anna lived and worked as a nurse. His father, also named Jiří, was a teacher in a local Czech school. Drahoš studied at the University of Chemistry and Technology in Prague and qualified as a scientist in 1972. He joined the Institute of Chemical Process Fundamentals at the Czech Academy of Sciences, and was later head of the institute from 1996 to 2003. On 13 March 2009, Drahoš was elected President of the Czech Academy of Sciences, defeating Eva Syková. During his tenure, he successfully opposed 50% budget cuts to the Academy proposed by the governments of Prime Ministers Mirek Topolánek and Jan Fischer as a consequence of the 2008 financial crisis. Drahoš later called it an "attempt to destroy my motherly institution". In 2012, President Václav Klaus awarded him the Medal of Merit in the field of science. His second term as head of the academy ended on 24 March 2017. He is co-author of 14 patents.

Political career

2018 presidential campaign On 28 March 2017, Drahoš announced his intention to stand in the 2018 presidential election. On 24 April 2017, he started gathering the signatures required to be registered as a candidate. In July 2017, after meeting with Drahoš, the leaders of Populars and Mayors, Pavel Bělobrádek and Petr Gazdík, announced that they would ask their respective parties' members to nominate and endorse Drahoš's candidacy. Mayors and Independents endorsed Drahoš on 25 July 2017 while the Christian and Democratic Union – Czechoslovak People's Party (KDU–ČSL) endorsed him on 14 November 2017. Young Social Democrats also endorsed Drahoš on 9 December 2017. Polls in late 2017 showed Drahoš as the second strongest candidate behind Zeman. Drahoš received campaign donations from several influential businessmen, including Dalibor Dědek, Jiří Grygar and Luděk Sekyra. Drahoš started gathering signatures for his nomination in May 2017. On 19 August 2017, Drahoš announced he had gathered 78,000 signatures. He submitted his nomination on 3 November 2017 with 142,000 signatures. On 4 November 2017 on Facebook, Drahoš criticized Mirek Topolánek, who had announced his candidacy that day, describing Topolánek as similar to Miloš Zeman and calling his candidacy a bad joke. The two candidates met during a presidential debate at Charles University; Drahoš reflected that the status he posted was "Topolánek-like", to which Topolánek replied that it was written either by "a woman or PR mage". Drahoš received media attention when he expressed his fear that the election could be influenced by Russia. He met outgoing Prime Minister Bohuslav Sobotka to discuss the matter and stated he would also meet the new Prime Minister Andrej Babiš. The incumbent president Miloš Zeman criticized Drahoš and compared his actions to Hillary Clinton's when she lost to Donald Trump. Drahoš received criticism when he published a status on social media about Václav Klaus' amnesty, when it was revealed that he had copied a similar status by his fellow presidential candidate Michal Horáček. Drahoš apologised and attributed the mistake to an external member of staff. The first round was held on 12 and 13 January 2018. Drahoš received 1,369,601 (26.6%) votes, and advanced to the second round against the incumbent president Miloš Zeman. In the second round, held on 26–27 January 2018, Drahoš received 48.63% of the vote and thus lost to Zeman. Drahoš conceded defeat to Zeman, telling a crowd of his supporters that "I would like to congratulate election winner Miloš Zeman".

Senate Following the 2018 presidential election, Drahoš vowed to remain in public life, and in March 2018 announced his bid for the Prague 4 Senate seat in the 2018 election, nominated by Mayors and Independents and supported by TOP 09, KDU–ČSL and the Green Party. He won the election outright in the first round, with 52.65% of the vote. At the beginning of November 2022, Drahoš was elected 1st Deputy President of the Czech Senate replacing Jiří Růžička, having received 67 out of 80 votes in a secret ballot. In the 2024 Czech Senate elections, he defended his seat as a non-party member of STAN in Senate District No.20 - Prague 4, with the support of STAN, Pirates, ODS, KDU-ČSL and TOP 09. He won the first round of the election, receiving 48.21% of the vote. On 30 October 2024, he was re-elected as the 1st Deputy President of the Senate, with 61 votes from the 79 senators present.

Worked examples

Example 1 — a first encounter with Jiří Drahoš

Start with the simplest possible case. Write down what Jiří Drahoš 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 Jiří Drahoš 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 Jiří Drahoš 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 Jiří Drahoš

In research
Jiří Drahoš 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 Jiří Drahoš 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
Jiří Drahoš is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 births, Candidates in the 2018 Czech presidential election, Czech chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Jiří Drahoš 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.
