Thai National Observatory

Thai National Observatory 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 Thai National Observatory rather than just read about it. In short: Thai National Observatory (TNO) is in Doi Inthanon National Park, Chom Thong District, Chiang Mai Province, Thailand. Atop Thailand's highest mountain, Doi Inthanon, this observatory is part of the National Astronomical Research Institute of Thailand, and is its main facility.

Key takeaways

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

Reference excerpt

Thai National Observatory (TNO) is in Doi Inthanon National Park, Chom Thong District, Chiang Mai Province, Thailand. Atop Thailand's highest mountain, Doi Inthanon, this observatory is part of the National Astronomical Research Institute of Thailand, and is its main facility.

Facilities The TNO has of two sections—the main observatory, and an auxiliary station lower on the mountain with offices and lodging for astronomers, facilities for public outreach activities (like school groups), and a small permanent exhibition for the public. Because the observatory is located in a national park, it was built to minimize environmental impact.

Equipment 2.4-meter reflecting Ritchey–Chrétien telescope with altazimuth mount, known as the Thai National Telescope (TNT). The telescope control system also controls movement of the dome automatically. The telescope itself was manufactured in Tucson, Arizona at EOS Technologies, Inc. (EOST). The primary mirror was fabricated and polished at the Lytkarino Optical Glass Factory (LZOS) in Russia. It is the largest optical telescope in the region. The TNT is used for research by NARIT astronomers and visiting researchers. 0.5-meter Schmidt-Cassegrain robotic telescope. This is similar to the type used at NARIT's regional observatories. It is used for training and education, testing new instrumentation and techniques, supporting the main telescope, and research that does not require the use of the main telescope. 2k x 2k CCD photometer with an BVRI filter system A research-grade 4k x 4k CCD photometer with an BVRI filter system A high-resolution echelle spectrograph (scheduled for use in 2014)

Worked examples

Example 1 — a first encounter with Thai National Observatory

Start with the simplest possible case. Write down what Thai National Observatory 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 Thai National Observatory 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 Thai National Observatory 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 Thai National Observatory

In research: Thai National Observatory 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 Thai National Observatory 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: Thai National Observatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical observatories in Thailand, Astronomical observatory stubs, Thailand stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Thai National Observatory 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.
