Lifewire

Lifewire 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 Lifewire rather than just read about it. In short: Lifewire is a technology information and advice website. The website's owner is Dotdash Meredith, originally About.com, which launched Lifewire in 2016 as one of its spin-off vertical sites.

Key takeaways

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

Reference excerpt

Lifewire is a technology information and advice website. The website's owner is Dotdash Meredith, originally About.com, which launched Lifewire in 2016 as one of its spin-off vertical sites. As of April 2022, it had a global website ranking of 1432 by Alexa Internet.

History Lifewire was the third standalone brand of About.com, an IAC-owned media company, which broke up its collections of DIY and how-to information into branded vertical websites, and is a competitor to sites such as Techcrunch, Techradar, PCmag. Lifewire was preceded by Verywell, a health info website, and The Balance, a personal finance site. Lifewire became a top 15 technology website in the United States as it was launched in October 2016. It was a top 10 technology-information site in 2017, reaching 6 million monthly US unique users each month. The purpose of Lifewire is to offer advice and answers on common technology questions and problems in a simplified format. When it was launched, Lifewire featured 16,000 articles written by 40 people. Lifewire CEO described the website style "as if your BFF happened to be an iPhone expert."

Worked examples

Example 1 — a first encounter with Lifewire

Start with the simplest possible case. Write down what Lifewire 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 Lifewire 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 Lifewire 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 Lifewire

In research: Lifewire 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 Lifewire 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: Lifewire is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 establishments in the United States, American technology news websites, Internet properties established in 2016, so understanding it makes those chapters shorter.
In everyday life: Look for Lifewire 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.
