John Abraham (engineer)

John Abraham (engineer) is a engineering 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 John Abraham (engineer) rather than just read about it. In short: John P. Abraham is a professor of thermal sciences at the University of St.

Key takeaways

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

Reference excerpt

John P. Abraham is a professor of thermal sciences at the University of St. Thomas School of Engineering, Minnesota in the United States of America. He teaches and carries out research in mechanical engineering in the thermal sciences, biomedical engineering, renewable energy, climate change and with other engineered devices. In 2009 he started to analyze misrepresentations being used to promote climate change denial, and from 2010 became a prominent defender of science in the global warming controversy. In that year, he helped to launch the Climate Science Rapid Response Team.

Career Abraham is professor of thermal science (thermodynamics) and fluid mechanics at the University of St. Thomas School of Engineering, Minnesota. His area of research includes thermodynamics, heat transfer, fluid flow, numerical simulation, and energy. After gaining his doctorate at the University of Minnesota in 2002, he joined St. Thomas as an adjunct instructor, later becoming a full-time member of the faculty. He has published over 450 papers in journals and conferences, and since 1997 has also been an engineering consultant working on industrial research in aerospace, biomedical, energy and manufacturing industries. He has also served as an expert witness in numerous scald and injury lawsuits and for intellectual property (patent) cases. He works on clean and renewable wind and solar projects in the developing world, and has also produced numerous books, such as a 2014 text on small-scale wind power and a 2010 groundbreaking text on laminar-to-turbulent fluid flow.

Refutation of climate change denial Abraham felt it was necessary to respond to a talk given to the Minnesota Free Market Institute in October 2009 by a well-known denier of human-caused global warming, Christopher Monckton. He thought "this guy is a great speaker and he is very convincing. If I didn't know the science, I would believe him. Frankly, the nonscientists in the audience didn't have a chance. They had no way of knowing what he said was not true. I felt Monckton took advantage of them and he knew he was taking advantage of them." In the following months he carried out research, contacting scientists cited by Monckton, and in late May 2010, he posted online an 83-minute video rebutting Monckton's statements. This attracted little attention at first, until it was highlighted by an article George Monbiot published in The Guardian. Abraham's presentation and the response from Monckton subsequently received world-wide attention. More recently, Abraham and a number of colleagues including Michael E. Mann submitted a document to the United States Congress which set out to refute nine errors in Christopher Monckton's May 6, 2010, testimony. In November 2010, Abraham (and two colleagues, Scott Mandia and Ray Weymann) launched the Climate Science Rapid Response Team, to provide rapid, high-quality scientific information to the media and government decision-makers. The intention of this group is to enable scientists to share their work directly with the general public. This effort has been covered by many media outlets. The effort has an online page for media to submit their questions. Abraham estimated early in 2012 that since beginning his rebuttal he had put around 1,000 unpaid hours into work on climate change and the controversy. He has given numerous speeches to publicize global warming issues, but does not accept funding for climate research or ask for an honorarium for speeches: if payment is given he asks that it goes to St. Thomas or to charity.

Worked examples

Example 1 — a first encounter with John Abraham (engineer)

Start with the simplest possible case. Write down what John Abraham (engineer) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 John Abraham (engineer) 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 John Abraham (engineer) 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 John Abraham (engineer)

In research
John Abraham (engineer) appears in engineering 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 John Abraham (engineer) 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
John Abraham (engineer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American mechanical engineers, 21st-century American physicists, American climate activists, so understanding it makes those chapters shorter.
In everyday life
Look for John Abraham (engineer) 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.
