SN UDS10Wil

SN UDS10Wil 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 SN UDS10Wil rather than just read about it. In short: SN UDS10Wil (SN Wilson) is a type Ia supernova, and as of April 2013, the farthest known. It has a redshift of 1.914, which strongly implies that it exploded when the universe was about a third of its current size.

Key takeaways

SN UDS10Wil belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SN UDS10Wil to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SN UDS10Wil from memory before moving on to harder problems.

Reference excerpt

SN UDS10Wil (SN Wilson) is a type Ia supernova, and as of April 2013, the farthest known. It has a redshift of 1.914, which strongly implies that it exploded when the universe was about a third of its current size. It was discovered with the Hubble Space Telescope's Wide Field Camera 3. The nickname SN Wilson is after the American President Woodrow Wilson.

Worked examples

Example 1 — a first encounter with SN UDS10Wil

Start with the simplest possible case. Write down what SN UDS10Wil 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 SN UDS10Wil 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 SN UDS10Wil 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 SN UDS10Wil

In research: SN UDS10Wil 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 SN UDS10Wil 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: SN UDS10Wil is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 2013, Cetus (constellation), Type Ia supernovae, so understanding it makes those chapters shorter.
In everyday life: Look for SN UDS10Wil 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.
