## Welcome to Mathematics Educators Stack Exchange

Mathematics Educators Stack Exchange is a question and answer site for those involved in the field of teaching mathematics. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about teaching mathematics.

We're a little bit different from other sites. Here's how:

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

# Earliest real-world uses of Calculus and Linear Algebra

I want to illustrate in class that real-world applications of mathematics might take time to come to fruit. In this context, I want to find what the earliest real-world applications of Calculus and Linear Algebra were. By real-world application, I mean a device, instrument or technology which made lives better and would have been simply impossible without Calculus or Linear Algebra.

Maybe Archimedes' figuring out that the volume of a sphere is 2/3 the volume of the smallest cylinder surrounding that sphere? This work was performed some time in the third century BCE.

Back in Greece long ago around 400 to 200 BC by Eudoxus and Archimedes according to Wikipedia calculating the area under a parabola for instance.

## Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

• Specific issues with teaching mathematics
• Real problems or questions that you’ve encountered

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

• Anything not directly related to teaching mathematics
• Questions that are primarily opinion-based
• Questions with too many possible answers or that would require an extremely long answer

## Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.
