This is to be the first posting here. It features an illustration attempting to visually teach anyone the concept of statistical analysis using the Pie Chart. Essentially, we see two people at a table with 8 bottles. The pie chart helps summarize what's on the table.. or rather, in the bottles, by showing how we have 2 empty bottles, and 3 different drinks we might label A (dots), B (green), C (stripes) distributed across the remaining 6 bottles as such: A:2, B:3, C:1

Starting from this simple illustration, much of statistical analysis at any level can be taught to any student or learner at any level.

Before we proceed... Note that there's enough chalk, to take us for several lectures to follow... So, worry not. 😄

Other ways to apply/use blackboards?

**Dynamic Signage**

Basically, here we see an example of what JWL loves to call a "Blackboard Computer", or rather, "BC", being used to communicate to visitors at Menuza Bytes ( https://menuzabytes.com ) that where they've come is a shop 🤞😄

Another example of BC serving as signage...

A Unified Exam

Essentially, if anyone walks past this blackboard, they are invited to attempt to solve at least one of the problems given. The examiner had tried to split up the exams, based on level: University, Secondary, Primary and the one on the extreme right, left for babies or the unschooled ;)

Of course, someone at the level of for example Secondary, should likewise challenge themselves to answer correctly the lower level problems as well 🤞😄

That's a session at the Menuza Bytes BC some time in the past...

Exploring some ideas in architecture...

Cryptic Hand? Maths or Weird Hieroglyphics?

This is somewhat both Esoteric and Advanced

JWL calls this The Crypt of Medina (CoM). Not sure why. But, it is a key, first of all, to read and write in the somewhat strange, but useful _language between the lines_; essentially, any message can be rewritten using this language, and it would never make sense to anyone that doesn't understand or know about this key. Also, CoM could be used to put secrets in the face of the public without giving away the secrets, something known as cryptography in technical circles.

In this key, the first two lines on the left express the alphabet from A to N, while the second column expresses O to Z. This key is incomplete here because it says nothing about the numerals for example. But that's it for now.

So, we recently said something about boards that don't use chalk? Well... Here's a snapshot of JWL'S work on a whiteboard hahaha.. Yes! Year was 2011, and he had just completed his first degree from Makerere. Bachelor of Science (P, M, Cs major). His final project dealt with Crime Analysis, and here we see his work and ideas developing a method for predicting and classifying crimes using maths and some artificial intelligence...
