Lasers are cool. Their insane etching resolution let us cram in every fundamental physics equation and basically the entire inner cover reference of a textbook. Avoid the distraction of Googling values and keep moving on that calculation with everything you need right there in your pocket.
Your lab's best friend
No more wasted hours scouring the lab for that one ruler. Quickly measure height offsets with the edge-zeroed ruler and sketch diagrams with built-in protractor. There's even a tiny flat head screwdriver on one corner!
