The Pocket Scientist - Scientific Ruler and Reference
$12.95
Carry your passion for science in your pocket.
This laser-cut, laser-engraved, 0.5 mm enamel-coated stainless steel scientific pocket 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!
STEM ESSENTIALS LASER-ETCHED INTO A WALLET-SIZED STAINLESS STEEL CARD:
- Imperial and metric straight-edge to 85 mm with machinist ruler to 10-mil resolution (254 um)
- 12 physical constants and 14 fundamental equations from physics and chemistry
- Temperature, mass and pressure unit conversions plus trigonometry quick-reference
- Arc and circle drawing protractor tools with 1/8th inch or 5 mm resolution
- Full periodic table with atomic number reference in each period (row)
- Phone stand slot (insert another sturdy credit card)
- 42 digits of Pi (because we could)
- QR code which links to rotating monthly Easter-eggs on a hidden GLG page
- 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 starting school or at graduation!

Great for field notes
"To start, I am the guy who has a pocket ref in my laptop bag. I bought this tool to go into my Field Notes wallet. It appears well made and amazingly enough it doesn't have a bottle opener (I was beginning to believe it was a law to have a bottle opener on any small bit of metal for sale). The finish is uniform, the print is legible and, there are no burs or other manufacturing defects.
I would recommend this to anyone who likes to have some basic scientific data on hand and small ruler as long as they don't intend to sit on it."

"You don't have to be a rocket scientist...
"...to appreciate this item. At first glance, it's the ultimate in science nerd gear and an interesting conversation piece. But it's more than that. It's a well-made item and I find the measuring scales to be accurate and useful. The physics formulas and constants are handy if you don't have them memorized. I find the periodic table to be useful when I come across a reference to a more obscure element (I have trouble recalling the location of the elements beyond number 40). I think this item will make a delightful gift for anyone who successfully completes (survives) a course in physics, chemistry,or engineering."

Customers praised this scientific ruler card as a high-quality, well-made tool perfect for STEM students and professionals. "Information clearly etched into the metal," noted shoppers who appreciate its durability. Features include formulas, periodic table, protractor, and measuring scales. Most loved it as a gift. Minor concerns: one periodic table typo and thin metal could bend if sat on.
- Information on these pocket scientists so clearly etched into the metal. Expect them to last!
- Perfect size, all the formulas he could ever want, and super useful for drawing lines.
- Great quality material and etching. Really easy to read, very solid.

Nice product, it was gift for my son he liked it a lot.
E
We purchases 3 of these. Our 14yr old loved them. He was so excited to find they were more than a measuring tool. The quality is spot on and I will definitely be buying more.
E
Excellent gift for stocking next Christmas!

It was too late arriving make sure about delivery times before ordering
C
I didn't expect the information on these pocket scientists to be so clearly etched into the metal. I expect them to last a while! Excited to use them for years to come.
E
I already had bought the pocket paleontologist for myself and loved it. I got an engineer friend of mine one for christmas and it was a hit.

Awesome Quality and Excellent Detail ! 4th item I’ve ordered from this Shop ! Wonderful and Superb timeliness ! Thank you so very much !

Ordered this for a small present for a teacher. such great quality material and etching. really easy to read, very solid. all the important notes that might be useful. just so neat and well designed.
There was a slight issue with postage, but once i contacted them everything got sorted out very proffessionally, and it even arrived in time still, so really pleased with the level of service too.

These are awesome. It’s important to have a card like this in my job. I have a plastic one and it worn out. These will be perfect in my job
S
Like others have said, its well made and designed, and just really cool. I would have made the periodic table a little bigger and the company name a little smaller, but I suppose thats a minor gripe. Still, the table on this one could be bigger, to compensate for the chemist one being smaller. I have all 3 and like them all.
H
This product works very great for when you need to take a quick measurement or when you forget an equation to accurately solve a problem regarding the electrics of a certain building or vehicle.
E
My daughter, a physics & math major, says this is going to be of SO much help during physics labs, so she won't have to look up all the functions anymore - she has this quick reference. The protractor and ruler will be helpful, too, she said. Thank you!
E
I love that this is out there. So handy. Great stocking stuffer for any student.
E
Love it! Wish it was slightly thicker though
