N. Jeremy Kasdin

N. Jeremy Kasdin 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 N. Jeremy Kasdin rather than just read about it. In short: N. Jeremy Kasdin is an American astrophysicist pursuing research into the detection and characterization of exoplanetary systems.

Key takeaways

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

Reference excerpt

N. Jeremy Kasdin is an American astrophysicist pursuing research into the detection and characterization of exoplanetary systems. He is the assistant dean of the engineering school at the University of San Francisco. Prior to this, he was a professor at Princeton University and vice dean of the School of Engineering and Applied Sciences. He is a pioneer of the starshade technique for suppressing starlight to enable the direct detection of Earth-like planets around nearby stars. He is also a recognized authority on orbital dynamics and optimal estimation of physical state, and co-authored the book "Engineering Dynamics: A Comprehensive Introduction". His earlier work included involvement with NASA's Terrestrial Planet Finder mission, a mission studied in the 2000s; an innovative concept for a planet-finding telescope with an unusual pupil, and Gravity Probe B. Kasdin has also been involved with developing a means of tracking birds or other migratory animals anywhere in the world. He is currently the leader of the coronagraph science (the Adjutant Scientist) for NASA's Nancy Grace Roman Space Telescope mission. Kasdin's work on shaped pupil coronagraphy, one of the techniques being developed for Roman, has demonstrated high contrast imaging over a restricted field of view near a bright object such as a star.

Worked examples

Example 1 — a first encounter with N. Jeremy Kasdin

Start with the simplest possible case. Write down what N. Jeremy Kasdin 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 N. Jeremy Kasdin 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 N. Jeremy Kasdin 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 N. Jeremy Kasdin

In research: N. Jeremy Kasdin 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 N. Jeremy Kasdin 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: N. Jeremy Kasdin is common in secondary-school and first-year university syllabi. It links to neighbouring topics American astronomers, Living people, Princeton University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for N. Jeremy Kasdin 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.
