Mathemagic for error detection and correction

Junior_U

The ANU College of Engineering and Computer Science is hosting a series of free workshops designed for primary school students in years 3-6 and their parents and carers. These hands on workshops will introduce participants to exciting concepts in a fun and educational way and provide many opportunities to have their questions answered about engineering, computing and technology.

How do you know that the happy emoji you just sent to your friend won’t end up being an angry one?

When data is stored on a disk or transmitted from one computer to another, we usually assume it doesn’t get changed in the process. But sometimes things can go wrong and the data is changed accidentally, or perhaps on purpose.

This activity uses a mathemagic trick to show how to detect when data has been corrupted. We’ll also see how to use codes to correct corrupted data, and how it is used in real life.

We have reached the maximum number of registrations for this session.
