Reference excerpt

Uzi Even (Hebrew: עוזי אבן; born 18 October 1940) is an Israeli professor emeritus of physical chemistry at Tel Aviv University and a former politician well known for being the first openly gay member of the Knesset (the Israeli Parliament).

Biography Uzi Even was born in Haifa during the British Mandate era. He earned a BSc and MSc in physics at the Technion, and a PhD at Tel Aviv University. His specializations are spectroscopy of super cold molecules, molecular clusters and cluster impact chemistry, and the quantum properties of helium clusters. He then worked as a scientist at the Negev Nuclear Research Center near Dimona. As a reservist in the Israel Defense Forces he reached the rank of Lieutenant Colonel. He conducted top-secret military research and served as an intelligence officer during the Six-Day War and Yom Kippur War. In 1968 he left his job at the reactor and joined Lekem, an Israeli intelligence agency responsible for collecting scientific and technical information from abroad. In May 1981, Even leaked the news of preparations to carry out "Operation Opera" to opposition leader Shimon Peres. Peres subsequently wrote a letter of protest to Prime Minister Menachem Begin, and the operation was delayed for a month. In 1982, Even had his security clearance revoked and rank lowered in the IDF reserves and was reassigned to a clerical position after his sexual orientation was discovered. At the time, the IDF's policy prohibited known homosexuals from holding security clearances. In 1993, he participated in the first Knesset hearing on gays and lesbians, and spoke about his ordeal in the IDF over his sexual orientation. His testimony led to Yitzhak Rabin's government changing the law and regulations to allow homosexuals to serve in the army in any position, including one requiring a high security clearance. In 1996, after Even's employer, Tel Aviv University, refused his then-partner, Amit Kama, spousal rights equal to those it granted to the spouses of staff in heterosexual marriages, he sued the university with help from the Association for Civil Rights in Israel. Even won the case, setting a legal precedent. In 2004, Even and Kama married in Canada. On 10 March 2009, the Family Court ruled that Even and Kama could legally adopt their 30-year-old foster son, Yossi Even-Kama, making them the first same-sex male couple in Israel whose right of adoption was legally acknowledged. In December 2012 Even set yet another legal precedent by divorcing Kama. The divorce was granted by the Family Court, since the Rabbinical Court does not recognize same-sex marriages. This might lead the way for straight couples to bypass the religious establishment as well, which - in Israel - holds monopoly on marriage and divorce affairs.

Political career A member of Meretz, he narrowly missed out on being elected to the fifteenth Knesset in 1999, but as the next placed candidate on the party's list, he became an MK when Amnon Rubinstein resigned in 2002, making him the first openly homosexual member of the Knesset. For the 2003 elections he was placed 15th on the party's list, and lost his seat when they won only six seats. In 2006, Even announced he was leaving Meretz and joining the Labor Party, feeling comfortable doing so after he noticed that Labor promised equality to all citizens in its election manifesto.

Worked examples

Example 1 — a first encounter with Uzi Even

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

In research: Uzi Even appears in astronomy 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 Uzi Even 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: Uzi Even is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 20th-century Israeli military personnel, 20th-century Israeli scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Uzi Even 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.
