Encoding the World. The Metaverse will some day very real. This lesson students will learn how we are able to represent real world things into a form a computing can understand.
Understanding the modern human's number system: Decimal
In this lesson students will learn the names of number systems and their latin prefixes.
Octonary? Really? It's just Octal, also known as Base 8. Nanonary is Base 9.
Base 5 - Quinary, Quinquenary
Base 6 - Senary/Sexenary
Base 7 - Septenary
Base 3 - trinary, ternary
Base 4 -quaternary
Understanding hexadecimal as well as any number system
Finally, Base 2. What we've been waiting for.
It's helpful to use our hands for counting. We've done it for years but how would you do that if it's not a BASE 10 number system, since we have 10 fingers.
Not going to lie. This lesson might hurt your brain. This is where it all comes together.
What is data and how do we convert the world into useful information?
No Additional Charge
If data is the facts about the world around us we need to learn about all the various types in comes in.
Students now understand types of data but how do we store that data on a computing device.
Computer Scientist can only work with data that is measurable: Discrete Data
We rarely work with Finite Data.
What's the difference
Lessons on the various character encoding standards used today like ASCII, UTF-8 and Unicode
Our first images on a computing device were only in black and white, aka Monochrome.
Encoding color as part of the digital pixel.
Black and white, on and off, zero and one. Now we encode with 16 symbols.

Lossy, Glossy and Lossless image compression
Understand how Vector graphics are different to raster images (pixel graphic images).
We want to discuss how we encode the data time of music but before we do that we need to understand these 2 concepts
After the previous lesson, students understand digital vs analog allowing us to discuss digital music.
What does Encoding a Video Mean? What is Video Compression? What are Codecs? Video Encoding vs. Transcoding: What’s the Difference?
How do we classify "Big Data" from little data?
Bit, Byte, Kilobyte, Megabyte, Gigabyte is our small data but what about the really big stuff?
If we can measure data and store data we have to know how much we can hold.
A deeper dive into how image size is determined?
Challenge Time. The entire lesson will be purely focused on recall.
In order to turn all the data in the world into useful information, we have to learn to sort it.
Okay, let's dig in. Time to learn how to sort data using the technique called "Bubble Sort".
