Helena Sheehan

Helena Sheehan is a astronomy 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 Helena Sheehan rather than just read about it.

Key takeaways

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

Reference excerpt

Helena Sheehan is an Irish philosopher, historian of science, philosophy, culture and politics. Sheehan is professor emeritus at Dublin City University, where she taught media studies and history of ideas in the School of Communications. She was a visiting professor at the University of Cape Town and Peking University on several occasions. She has been active on the left since the 1960s. She has given many conference papers and public lectures in universities and other bodies in USA, USSR, GDR, Mexico, Canada, Ireland, UK, France, Germany, Italy, Czechoslovakia, Yugoslavia, Greece, China and South Africa.

Biography Born in the United States in 1944, Sheehan describes her childhood as Catholic and conservative, She began her university studies and taught primary school as a nun. She left the convent in 1965 and became an agnostic and liberal, then an atheist and radical. Sheehan graduated with a BS in 1967 from St. Joseph's University in Philadelphia, followed by an MA in 1970 from Temple University in Philadelphia. Sheehan attended the International Lenin School in Moscow, Soviet Union in 1977-1978. She earned a PhD in 1980 from Trinity College (Dublin) in philosophy. Sheehan became active on the new left in the US in the 1960s. In Ireland, she joined Sinn Féin (Official) in 1972 and then the Communist Party of Ireland in 1975. She chaired the Trinity College Dublin Communist Society. She joined the Labour Party in 1981, where she was a founder of Labour Left. Since 2011, she has belonged to no party, but has remained active on the left. She organised Occupy University during Occupy Dame Street in 2011. She travelled often to Greece and became involved with Syriza, writing about this in The Syriza Wave published in 2017. An autobiographical work entitled Navigating the Zeitgeist was published in 2019 with a sequel Until We Fall published in 2023. As a philosopher and historian of science, Sheehan writes from a Marxist perspective. She argues that Marx and Engels shared fundamentally the same view on the philosophy of science and written critically of Lysenkoism and Stalin's impact on scientific development, while stressing the necessity of understanding such trends in full socio-historical context. She is a strong critic of both positivism and postmodernism. Sheehan has lectured at the Humanist Association of Ireland. In her personal life, Sheehan was the partner of the trade unionist Sam Nolan.

Quotes On her life:"Sometimes I feel as if I have lived eons in a matter of decades. The wave of historical change, such as swept over centuries in the past, seem to have swept through my world several times over already. And who knows what I have yet to see? I am perhaps only halfway through the time I may expect my life to be." [1988] On Marxism:"Whatever Marxism is, it is systemic analysis and historical perspective. It is a totalising (not totalised) philosophy of history. It is the only mode of thought able to give a coherent, comprehensive, and credible account of the complexity of contemporary experience. It is the only coherent analysis of the capitalist mode of production and how it structurally generates, not only the maximum expropriation of surplus value, but maximum dissolution of social bonds, involving decreasing access to totality and increasing atomisation of thought processes. It is the only credible analysis of an alternative mode of production, proposing socialism, not only as a radical restructuring of the relations of production, but as a fundamental transformation of patterns of thought and forms of social organisation." On Marxism and science:"Marxism has made the strongest claims of any intellectual tradition before or since about the socio-historical character of science, yet always affirmed its cognitive achievements. Science was seen as inextricably enmeshed with economic systems, technological developments, political movements, philosophical theories, cultural trends, ethical norms, ideological positions, indeed all that was human. It was also a path of access to the natural world." On Lysenkoism:"What went wrong was that the proper procedures for coming to terms with such complex issues were short-circuited by grasping for easy slogans and simplistic solutions and imposing them by administrative fiat. On the fall of communism:"These are the days of our defeat, we ought not to pretend otherwise, but defeat is not death. On the death of communism:"The socialist experiment has been portrayed as having played itself out and finally thrown up leaders who have seen the superiority of the capitalist way and decided to go for it. The world is 'going our way', the leaders of 'the free world' have declared. The iron curtain has come tumbling down. The Kremlin has been conquered without a single marine opening fire, without a single ICBM being launched. It unravels before me like a nightmare. No more the red flags flying. No more the heads held high and the fists clenched and the voices raised to the strains of The International. No more the larger-than-life murals of workers and soldiers and peasants marching into the future shaping the world with the labour of their hands and hearts and minds. Now it is to be Mickey Mouse and Coca Cola and Michael Jackson and Sacchi & Sacchi."

Worked examples

Example 1 — a first encounter with Helena Sheehan

Start with the simplest possible case. Write down what Helena Sheehan 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 Helena Sheehan 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 Helena Sheehan 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 Helena Sheehan

In research
Helena Sheehan 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 Helena Sheehan 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
Helena Sheehan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Irish philosophers, 21st-century Irish philosophers, Academics of Dublin City University, so understanding it makes those chapters shorter.
In everyday life
Look for Helena Sheehan 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.
