The Pocket Scientist - Wallet Science and Engineering Ruler

Regular price $11.50 Sale

Carry your passion for science in your pocket.

This laser-cut and laser-engraved 0.5 mm enamel-coated stainless steel reference card engineering ruler is designed for passionate scientists and engineers who may find themselves needing a quick straight edge, wondering what's next to Technetium in the Periodic Table, pausing to double-check the 6th significant figure in the speed of light or who somehow forgot the 42nd digit of pi. Keep it in your wallet at all times so you're always ready to do some science!

Features:

1) Imperial and metric straight-edge to 85 mm with machinist ruler to 10-mil resolution (254 um)

2) 12 physical constants and 14 fundamental equations from physics and chemistry

3) Temperature, mass and pressure unit conversions plus trigonometry quick-reference

4) Arc and circle drawing protractor tools with 1/8th inch or 5 mm resolution

5) Full periodic table with atomic number reference in each period (row)

6) Phone stand slot (insert another sturdy credit card)

7) 42 digits of Pi (because we could)

8) QR code which links to rotating monthly Easter-eggs on a hidden GLG page

9) Fits any normal credit card or ID holder. TSA compliant and more compact than a standard 6" engineering scale ruler.

Makes for a perfect unique gift for scientists or engineers starting school or at graduation!

Very handy when you can't be tied to your desk or a device

This is unique and excellent tool. I am a general chemistry lab instructor and I'm always getting asked question that require me to go look up basic information. This will live in my lab coat pocket so I will allways have it handy as I move around the lab from student to student.
