Another excellent video. I'm looking forward to the rest of this series. Thanks!

Fantastic. Should we be faced with the apocalypse, then being able to build calculating machines like this will be a great skill to have. Thank you.

Thank You. That was exactly what I was thinking. The best part is, that once you have memorized the way the rods can be made( which is quiet simple), you can reproduce a set of Napier's Bones wherever you are.

I studied in Edinburgh, home of Napier University, named after the good man. Merchiston is a district of Edinburgh.

I envy you. I've been planning on making a trip to Edinburgh for some years now, but didn't make it there yet. From what I have seen in films and on pictures, it must have many beautiful buildings from the middle ages.

Great explanation

Amazing. I've seen such primitive mathematical devices before, but seeing some that I was not aware of is very exciting and interesting. I'm always interested in learning new things, even if they are "old". It shows that the past isn't irrelevant at all and that's pretty cool. Props on the video. Bravo!! Keep on teaching!!

this was really great... other videos of the series..???

Extremely interesting and super useful device, which I was not aware of. I'm convinced that our ancestors were much smarter than most are today. They could actually THINK for themselves! Great videos...! You have certainly earned my subscription and I look forward to your upcoming projects.

Interesting video, I had no idea about such a device even existing. It felt a bit out-of-place with the wind turbines, however.

Hey. I guess I will show a lot of stuff in this series that nobody knows ( at least not anymore). I have a lot of material about wind turbines that I never used in any video and since I simply needed an example for an interesting calculation, I brought that in :D

Interesting video. What science museum did you visit (where is it)? If you ever go to Vienna, there is a great technical museum worth visiting. With best regards, Arthur

Pure geeky goodness.

It was very cool, though writ by hand seems still just as fast or faster than napiers bones.

I don't know. It's also a matter of training and personal taste. I make very little mistakes while calculating with Napier's bones, while I often forget to wright down numbers when I do it by hand. Other than that it sure is possible to do long multiplication very fast too. But Napier's Bones can also be used to calculate square roots. For that you have to add a so called "root bone" and I guess there is no "manual" method that works as good as that for calculating square roots of large numbers.

It is all rather interesting though, it's funny how much work people will do and how creative they become, when trying to find shortcuts.

Love your videos, they are very insightful and spur me on to continue learning and creating as well. Thanx

Yes, I guess you could do it this way and be interesting, Or you could program an app in about the same time it would take to cut the cardboard :). Edit: Whoops, I'm sorry. I guess I should have watched the video all the way before posting. x)

I am not impressed by jacked up multiplication table.
