No one knew that 2,000 years ago, the technology existed to build such a device. The Antikythera mechanism, pictured, is now widely regarded as the first computer. Found at the bottom of the sea aboard a decaying Greek ship, its complexity prompted decades of study, and even today some of its functions likely remain unknown. X-ray images of the device, however, have confirmed that a main function of its numerous clock-like wheels and gears is to create a portable, hand-cranked, Earth-centered, orrery of the sky, predicting future star and planet locations as well as lunar and solar eclipses. The corroded core of the Antikythera mechanism's largest gear is featured, spanning about 13 centimeters, while the entire mechanism was 33 centimeters high, making it similar in size to a large book. Recently, modern computer modeling of missing components is allowing for the creation of a more complete replica of this surprising ancient machine.

Just bought my own digital caliper/vernier instrument - I deserved to have my own. ±0.01mm is good enough for engineering stuff
digital readout and vernier scale are read very differently. the digitals hand you the answer and the vernier result is calculated.
https://en.wikipedia.org/wiki/Vernier_scale
go with the digitals if that is an option.

Right out of the box, the Mars Helicopter needs a software upgrade. Apple must have built it.

Still, AAPL is up 2.23% for the day while I'm typing this. Now, 2.24%.

I use work with both - I confused my entitling because we use both words inaccurately and interchangeablyLike all things analogue, you need to have a rough idea of your answer first or else be a mile out. I like that way if working - like margins of error that keep things real
my first question to the green apprentice is how long is the string that wraps around a 10 inch diameter pipe. if the answer is anywhere near 30 inches the kid has potential and can start cutting straps. if the answer is anything crazy high or low the kid is issued a broom and told to keep the fucker moving.
