    I'm just curious if anyone actually carries a slide rule as part of their edc. I'm currently an engineering student and now that I've replaced my Ti-89 with an nspire cx cas, I can't just carry an extra pair of batteries in case the calculator dies in the middle of a test. My solution was to start carrying an old Pickett slide rule. I don't have to worry about not being able to do trig or square roots anymore.

    Not sure if a smartphone is allowed for test taking, but they have great calculator emulator apps for phones these days.. I use an HP-12c on my iPhone.

    I don't exactly EDC, but, keep one in my toolchest at work next to the calipers and micrometers. More than once I've relied on it when the calculators have been destroyed.

    When I was a kid, I was the only person in the 3rd grade who knew how
    to use a slide rule. I was such a geek that I brought one school
    every day. My father taught how to use one.

    Maybe if you know you have a test coming up you could ensure you have fresh batteries by replacing them beforehand?

    Haven't used a slide rule since I was a young engineering student, back then we weren't allowed to use calculators for tests because using a calculator was cheating. Even had to use the old logarithim books.

    I am not sure if I should feel disgusted in myself for the fact that I am an engineer, yet I have never used a slide rule in my life...

    The problem is that some of the fancy new calculators are moving towards using dedicated rechargeable batteries (like a mobile phone or computer) rather than generic batteries. With my TI-83+ for example it just uses AAA cells, so I can easily keep a spare set in my bag and if it dies on me, it takes a matter of seconds to replace them and get it working again. On the other hand if you take zackplanets nspire with its rechargeable battery, if it runs out of power you are completely out of luck unless you have the charger with you and a plug handy. I would hope most would be prepared enough to remember and charge it before something important like an exam, but I also expect the sight of students flustered and calculatorless mid class because they forgot to check the batteries beforehand not to be an entirely uncommon sight.

    weird, it won't let me edit the post.

    it was supposed to be a pic of my citizen nighthawk, which has a slide rule in the bezzel.

    Own a slide-rule, want a watch with one in the bezel, but definitely don't EDC one currently. My TI-89 actually ran out of power before an exam once. The instructor had spare calculators for just such an emergency. Was a bit harder using an 83+ though.

    Bezel slide rule for a watch is cool. I use a scientific calculator app. My father was the last in our line to actually carry a slide rule.

    precisely. I'm usually pretty good at making sure its charged, but theres still the possibility that i will forget one of these days. The slide rule is just cheap insurance. Its not like its a big deal to carry it around.

    I have a couple of watches with slide ruler bezels; nifty feature but I can never remember how to use them
