This free promotion has ended. The books are available on Amazon.

Sunday evening pick. A Python book covering AI assistants is free on Kindle, with three other titles, until Tue 10 Nov 23:59 PT. Time remaining: ends Tue 10 Nov, 11:59 pm PT.

This analysis was published during a free Kindle week for four engineering books in November 2026.

Ask an AI assistant for a beam deflection function and you'll have tidy code in seconds, complete with comments. It may well be right. It may also use the wrong boundary condition, mix units or quote a formula that doesn't exist, and it will look just as confident either way.

Where assistants help

The strongest use is for the parts of programming that aren't engineering. Assistants are very good at reading a file format, cleaning up a table, drawing a plot or explaining an error message. For an engineer who knows the physics but not the syntax, that removes a real barrier. Getting useful results depends on clear prompts that state units, assumptions and the required method.

They're also useful for writing a first draft of tests, and for explaining unfamiliar code.

Where they go wrong

Risk rises as a task moves towards judgement. An assistant has no real notion of which method applies to your part, or whether a material value is suitable for design. It may pick a plausible number from memory. Unit slips are a particular concern, and the Mars Climate Orbiter loss in 1999 remains the classic warning about mismatched units between software.

Niche topics are the weak spot. The less often something appears in public sources, the more likely an assistant is to invent a plausible version.

A safer workflow

Treat generated code like work from a capable new graduate: helpful, and in need of review.

  1. Decide the method yourself and state it.
  2. Have the assistant write the code.
  3. Test it against a known answer you obtained independently.
  4. Read it line by line, checking each formula.
  5. Never paste proprietary data into a tool your employer hasn't approved.

That last point matters in aerospace, where drawings and data may be export-controlled or commercially sensitive. Running a model locally is one option, and our comparison of local and cloud AI covers the trade-offs.

Responsibility stays put

If an analysis is wrong, "the AI wrote it" won't help. The engineer who signs it remains accountable, which is the best reason to stay able to do the sum by hand.

Each book is free on Kindle for 5 days only, and only the Kindle ebook is free. Once you download it, it stays in your Kindle library. After the promotion it returns to its paid price, and nothing is asked in return.

Readers outside the US: the offer runs in every Amazon store that sells Kindle ebooks; check the price shows 0.00 before you click Buy.

Already read it?

If you read it and it helps, an honest rating or review on the Amazon store where you downloaded it would mean a lot. It is entirely optional.
