The week's engineering terms, one joke, and what's happening in the Tennessee Valley.
Plus 300 free engineering calculators, dB to delta-v — yours the moment you subscribe.
Is it really free?
The weekly Brief is free and stays free. So are all the calculators, the history pages, and every entry on the Reference Shelf. Subscribing doubles as your library card: the Huntsville history, the FE/PE quick-reference pack, and shelf privileges — for nothing but the email address.
What's this "library card" business?
The Reference Shelf (our engineer-first math reference) is free to read for everyone, always. Your subscription is your library card: pin entries to My Shelf, print clean one-page reference cards, search the shelf, and take the FE/PE quick-reference pack. The shelf remembers what you reach for.
Will you spam me?
One email a week (Mondays), four minutes to read, unsubscribe in one click that actually works. We don't sell the list, rent the list, or 'share with partners.' Ever.
What does a typical issue look like?
The week's five terms, each with its formula and why it matters, the Huntsville Pulse (lunch spots, lectures, meetups worth your time), one resource spotlight, and one dry joke at the bottom. The site posts a new term every weekday, themed — Failure Friday hits the hardest.
