Mark Leon

Mark Leon 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 Mark Leon rather than just read about it. In short: Mark Leon (1962 – April 2018) was a former civil servant with NASA Ames Research Center. His primary work was in education and communication systems.

Key takeaways

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

Reference excerpt

Mark Leon (1962 – April 2018) was a former civil servant with NASA Ames Research Center. His primary work was in education and communication systems.

Early life Mark Leon grew up in a rather rough East San Jose neighborhood, and graduated from James Lick High School in 1980. He originally began taking a slightly more academic route to life when he began hiding in the library from other high school students who were attempting to beat him up. He also attended San Jose State University and won a silver medal in the 1985 Collegiate National Judo Championships. He received his bachelor's degree in electrical engineering in 1986.

Communications work In the 1980s Leon was instrumental in establishing trans-Atlantic communication between American, French and English space agencies. In the 1990s he completed the first audio/video link to Antarctica. This was thought to be impossible at the time.

Affiliation with FIRST Robotics For many years Mark Leon worked as a Master of Ceremonies in many FIRST robotics competition events both on and off season. He was particularly well known for wearing a bright blue NASA coat and dying his hair the same color for these events and coined the phrase "Do the math, Save the world". He was widely cited as an inspiration to many high school students to build robots and impacted many career choices. He is also credited with the existence of a large number of FRC teams.

Robotics Alliance Project Beginning in 1998 Mark moved to the Robotics Alliance Project at NASA Ames. This department works primarily in educational and outreach projects and was estimated in 2006 to have reached more than 100,000 middle and high school students. He also ran the Ames Robotics Academy every summer.

Worked examples

Example 1 — a first encounter with Mark Leon

Start with the simplest possible case. Write down what Mark Leon 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 Mark Leon 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 Mark Leon 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 Mark Leon

In research: Mark Leon 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 Mark Leon 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: Mark Leon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, 2018 deaths, American male judoka, so understanding it makes those chapters shorter.
In everyday life: Look for Mark Leon 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.
