A watch that uses a quartz crystal to keep time. I think that's most of the watches in the world today. The way it works is... explained by the person replying to this comment who knows more about science than me.
So, the watch has this little quartz crystal in it. Quartz crystals vibrate at some certain frequency that is very reliable. So, the watch applies some amount of current to the quartz, which makes it vibrate a certain specific amount times per second, around 32,000 vibrations per second, I think. The watch counts the vibrations somehow (that's the part I can't remember) and changes the second on whatever number the quartz crystal vibrates by.
Edit: it's actually 32,768 times per second. So, every 32,768 vibrations, the watch changes the second.
Adding onto this great explanation... a key point is that the quartz crystal has to be carefully cut and shaped so that it vibrates at the desired frequency.
The amazing thing is, a cheapo quartz watch keeps time more accurately than super expensive "mechanical" watches, which keep time using gears and springs. Rolex brags that their fanciest mechanical "superior chronometers" drift no more than 2 seconds per day. Meanwhile a $16 quartz watch might drift about 0.5 seconds per day.
Nowadays, almost all timepieces (including computers and phones) use quartz crystals due to their accuracy, simplicity, low cost, and low power requirements. Quartz timekeeping was a true engineering revolution.
Got 10/10! Pretty rare occurance for me. Just to nitpick a little, herptology is the study of all reptiles and amphibians; ophiology is the study of snakes. Of course it doesn't really matter for the question, but I think it's always interesting to learn new ologies
I agree! But scientists like to name things using fancy Greek and Latin words because they sound cooler and more sophisticated. I think it's interesting having lots of different words though, it might get boring if we use the same words too often!
There used to be a commercial in the 1980s or '90s where a woman was talking about how reliable her watch was and said in an exaggerated Southern accent, "My husband's not around anymore, but my Seiko is!" That's the only reason I got that question right.
Incidentally (I just looked it up because I was curious), herpetology and herpes do come from the same root. In Greek "herpein" means "to creep." Reptiles are "herpeton" because they creep along the ground, but herpes creeps across the body, so they both ended up with the same root!
