Lasse Jensen

Lasse Jensen 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 Lasse Jensen rather than just read about it. In short: Lasse Jensen is a professor of theoretical chemistry at Pennsylvania State University whose works have appeared in such chemistry journals as the Journal of the American Chemical Society, Journal of Physical Chemistry A, Journal of Chemical Physics and the Chemical Society Reviews, among others. He got his bachelor's degree from University of Copenhagen in 1998 and two years later obtained master's from the same pla…

Key takeaways

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

Reference excerpt

Lasse Jensen is a professor of theoretical chemistry at Pennsylvania State University whose works have appeared in such chemistry journals as the Journal of the American Chemical Society, Journal of Physical Chemistry A, Journal of Chemical Physics and the Chemical Society Reviews, among others. He got his bachelor's degree from University of Copenhagen in 1998 and two years later obtained master's from the same place. Four years later he got his Ph.D. from the University of Groningen and till 2007 worked as a postdoc at the Northwestern University along with George C. Schatz. He is well-recognized by many honors and awards for the theoretical investigations of plasmon-enhanced vibrational spectroscopies and the development of a hybrid atomistic electrodynamics-quantum mechanical model. As of 2017 he is author or coauthor of over 100 peer-reviewed articles, generating more than 6400 career citations and an h-index of 45. Jensen is a recipient of the 2010 Presidential Early Career Award for Scientists and Engineers.

Worked examples

Example 1 — a first encounter with Lasse Jensen

Start with the simplest possible case. Write down what Lasse Jensen 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 Lasse Jensen 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 Lasse Jensen 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 Lasse Jensen

In research: Lasse Jensen 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 Lasse Jensen 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: Lasse Jensen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American chemists, American chemist stubs, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Lasse Jensen 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.
