Reference excerpt

Sonic the Hedgehog is a character created by the Japanese game designers Yuji Naka and Naoto Ohshima. He is the protagonist of the Sonic the Hedgehog franchise and the mascot of the Japanese video game company Sega. Sonic is an anthropomorphic blue hedgehog who runs at supersonic speed. He races through levels, collecting rings and avoiding obstacles, as he seeks to defeat his archenemy, Doctor Eggman. He is accompanied by supporting characters, such as his sidekick Miles "Tails" Prower, admirer Amy Rose, and rival Knuckles the Echidna. Sonic made a cameo in the arcade game Rad Mobile (1990) before starring in Sonic the Hedgehog, a platform game for the Sega Genesis, in 1991. Sega sought a mascot to compete with Nintendo's Mario, and Ohshima designed Sonic based on a prototype programmed by Naka. Sonic's design was influenced by a variety of sources, including Felix the Cat, Mickey Mouse, Michael Jackson, and Santa Claus; his pigmentation was chosen to match Sega's cobalt blue logo. Yuji Uekawa redesigned Sonic for Sonic Adventure (1998) to suit the franchise's transition to 3D computer graphics, with a more mature look designed to appeal to older players. Sonic media characterizes Sonic as an impatient, snarky drifter and daredevil who despises injustice. He frequently battles Eggman, a mad scientist who seeks to steal the mystical Chaos Emeralds and take over the world. Sonic can curl into a ball to attack enemies and use the Chaos Emeralds to become Super Sonic, a power-up transformation granting him greater speed and strength. He has appeared in over 100 video games, in addition to guest appearances in other Sega franchises and in crossover games such as Nintendo's Super Smash Bros. series. Jun'ichi Kanemaru voices Sonic in Japan, while his English voice has been provided by Ryan Drummond, Jason Griffith, and Roger Craig Smith. Sonic is one of the most famous video game characters and an established pop culture icon. Journalists regard him as one of the greatest video game characters and his popularity inspired many imitators. His likeness has been featured in merchandise and Sega sponsorships. The Sonic series is one of the bestselling game franchises and was key to Sega's success during the 16-bit era in the 1990s. Sonic has been adapted in comics, animations, and films, including a live-action film franchise distributed by Paramount Pictures in which he is voiced by Ben Schwartz.

Worked examples

Example 1 — a first encounter with Sonic the Hedgehog (character)

Start with the simplest possible case. Write down what Sonic the Hedgehog (character) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Sonic the Hedgehog (character) 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 Sonic the Hedgehog (character) 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 Sonic the Hedgehog (character)

In research
Sonic the Hedgehog (character) appears in science 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 Sonic the Hedgehog (character) 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
Sonic the Hedgehog (character) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Adoptee characters in film, Animal superheroes, Anthropomorphic hedgehogs, so understanding it makes those chapters shorter.
In everyday life
Look for Sonic the Hedgehog (character) 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.
