Julie Vinter Hansen

Julie Vinter Hansen 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 Julie Vinter Hansen rather than just read about it. In short: Julie Marie Vinter Hansen (20 July 1890 – 27 July 1960) was a Danish astronomer. She was the first woman in Denmark to earn an academic degree in astronomy.

Key takeaways

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

Reference excerpt

Julie Marie Vinter Hansen (20 July 1890 – 27 July 1960) was a Danish astronomer. She was the first woman in Denmark to earn an academic degree in astronomy.

Life

Early life Vinter Hansen was born in Copenhagen, Denmark.

Education While studying at the University of Copenhagen, she was appointed as a computer at the university's observatory in 1915. She was the first woman to hold an appointment at the university. She was later appointed observatory assistant and, in 1922, observer.

Career

Editor of Nordic Astronomy Review She was a very energetic worker, who, along with her normal work of observing and performing mathematical reductions of observations took on the task of editing the Nordisk Astronomisk Tidsskrift (Nordic Astronomy Review).

International Astronomical Union She later became Director of the International Astronomical Union's telegram bureau and Editor of its Circulars.

Work as Astronomer at University of Copenhagen By 1939, Vinter Hansen was the First Astronomer at the Observatory of the University of Copenhagen, widely known for her accurate computation of orbits of minor planets and comets.

Tagea Brandt Rejselegat Award In that 1939 she received the Tagea Brandt Rejselegat (travel award), given to women that have made big contributions on arts or science. With the award money (DKK 10.000 or 160,000 of actual US $) undertook a tour through the United States to Japan and back. On her return trip in 1940, the outbreak of World War II restricted her homeward journey.

Work in University of California She was awarded a Martin Kellogg Fellowship at the University of California which allowed her to work for a time in the United States. Also in 1940 she was awarded the Annie J. Cannon Award in Astronomy.

Return to Denmark Vinter Hansen was appointed Knight of the Order of the Dannebrog in 1956 and continued her career at the University of Copenhagen until 1960.

Death Julie Vinter Hansen died in 1960, from a heart-failure just days before her retirement, in her beloved vacation destination, the Swiss mountain village of Mürren, and was buried in Copenhagen. The minor planet 1544 Vinterhansenia, discovered by Finnish astronomer Liisi Oterma in the 1940s, was named in her honour.

Worked examples

Example 1 — a first encounter with Julie Vinter Hansen

Start with the simplest possible case. Write down what Julie Vinter Hansen 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 Julie Vinter Hansen 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 Julie Vinter Hansen 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 Julie Vinter Hansen

In research: Julie Vinter Hansen 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 Julie Vinter Hansen 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: Julie Vinter Hansen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1960 deaths, 20th-century Danish astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Julie Vinter Hansen 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.
