Stephanie Singer

Stephanie Singer is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Stephanie Singer rather than just read about it. In short: Stephanie Frank Singer (born 1964) is an American mathematician and politician in Philadelphia, Pennsylvania. Singer was a professor at Haverford College from 1991 to 2002 before founding Campaign Scientific, a computer data business for political organizations.

Key takeaways

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

Reference excerpt

Stephanie Frank Singer (born 1964) is an American mathematician and politician in Philadelphia, Pennsylvania. Singer was a professor at Haverford College from 1991 to 2002 before founding Campaign Scientific, a computer data business for political organizations. She was elected as a Philadelphia City Commissioner in November 2011.

Early life and education Singer was born in 1964 to Maxine and Daniel Singer. Her mother was a molecular biologist and her father was an attorney for Fried, Frank, Harris, Shriver & Jacobson. Singer graduated from Yale University and earned a Ph.D. in 1991 at New York University. She spent a year in graduate studies at Stanford University for computer science.

Career

Academic Singer was a professor at Haverford College from 1991 to 2002, where she earned tenure. She experienced sexual harassment while at the school, which she discussed in a 2017 article in The Chronicle of Higher Education. She founded Campaign Scientific, which provided data services to political organizations and businesses. In 2002, she began requesting data from the Office of the Philadelphia Commissioners, which is responsible for conducting elections in the city, to post the data on an unofficial website for the city's Democratic party. The commission would only provide data in paper form until Singer threatened to sue them in 2008.

Politics Singer became increasingly active in politics after volunteering to work on election data for the 2004 presidential campaign of John Kerry. In 2008, she was elected Democratic Party committeeperson for Philadelphia's 8th Ward, an influential position representing Center City. In 2011, she was elected as a Philadelphia City Commissioner, defeating 36-year incumbent Marge Tartaglione. She ran an aggressive campaign, describing her opponent as "an embarrassment". Her campaign was endorsed by the Philadelphia Daily News and John Dougherty and his IBEW Local 98. She was sworn into office on January 3, 2012. During her time in office, she clashed with the other commissioners, Republican Al Schmidt and Democrat Anthony Clark, as well as the chair of the Philadelphia Democratic Party, U.S. Representative Bob Brady. The day after the city's handling of the November 6, 2012 elections led to criticism of the commission, Schmidt and Clark voted to remove Singer as chair of the commissioner and appoint themselves as co-chairs. The Philadelphia Inquirer reported that the removal did not appear related to the election, however, and noted that the commissioners "had been bickering for months at their weekly public sessions over seemingly small issues" as well as Singer's vocal opposition to the state's new voter ID law. Prior to their election, Singer and Schmidt had both run as progressive reformers, and Schmidt had initially voted with Singer to appoint her chair. Singer's reelection attempt in 2015 was challenged by three Democratic voters for failing to obtain the required 1,000 signatures on nomination petitions, falling four short. In March 2015, Common Pleas Court Judge Joel Johnson removed her from the Democratic primary ballot. Her term as city commissioner ended in 2016. In October 2018, Singer launched a podcast entitled Defend Democracy! where she reflects on her experience as a former election official, data strategist, and successful candidate, with advice to those who have interests in entering politics.

Personal life She is the daughter of molecular biologist and science administrator Maxine Singer and the sister of historian Amy Singer. Singer married Stephen Fischer in 1993 in a ceremony officiated by Ruth Bader Ginsburg, then a judge for the United States Court of Appeals for the District of Columbia Circuit.

Worked examples

Example 1 — a first encounter with Stephanie Singer

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

In research
Stephanie Singer appears in mathematics 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 Stephanie Singer 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
Stephanie Singer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 births, 20th-century American mathematicians, 20th-century American women mathematicians, so understanding it makes those chapters shorter.
In everyday life
Look for Stephanie Singer 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.
