Jesse Sullivan

Jesse Sullivan is a science 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 Jesse Sullivan rather than just read about it. In short: Jesse Sullivan (born c. 1966) is an American electrician best known for operating a fully robotic limb through a nerve-muscle graft, making him one of the first non-fictional cyborgs.

Key takeaways

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

Reference excerpt

Jesse Sullivan (born c. 1966) is an American electrician best known for operating a fully robotic limb through a nerve-muscle graft, making him one of the first non-fictional cyborgs. His bionic arm, a prototype developed by the Rehabilitation Institute of Chicago, differs from most other prostheses, in that it does not use pull cables or nub switches to function and instead uses micro-computers to perform a much wider range of complex motions. It is also the first prototype which enables him to sense pressure.

History As an electrician, Jesse Sullivan accidentally touched an active cable that contained 7,000-7,500 volts of electricity. In May 2001, he had to have both his arms amputated at the shoulder. Seven weeks after the amputation, Jesse Sullivan received matching bionic prostheses from Dr. Todd Kuiken of the Rehabilitation Institute of Chicago. Originally, they were operated from neural signals at the amputation sites, but Jesse Sullivan developed hyper-sensitivity from his skin grafts, causing great discomfort in those areas. Jesse Sullivan underwent neural surgery to graft nerves, which originally led to his arm, to his chest. The sensors for his bionic arms have been moved to the left side of his chest to receive signals from the newly grafted nerve endings. While the prototype is being strengthened, Jesse Sullivan does day-to-day tasks using an older model.

Worked examples

Example 1 — a first encounter with Jesse Sullivan

Start with the simplest possible case. Write down what Jesse Sullivan 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 Jesse Sullivan 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 Jesse Sullivan 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 Jesse Sullivan

In research: Jesse Sullivan 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 Jesse Sullivan 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: Jesse Sullivan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s births, American amputees, American electricians, so understanding it makes those chapters shorter.
In everyday life: Look for Jesse Sullivan 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.
