Today in class we first started to talk about flow charts. After a brief discussion with Andy I soon remembered that I too had used this kind of format when I was doing programming in engineering, we would always start off with seudu code which would help is structure our programs. I also remembered these from when I was in school. After a few more examples I realized that flowcharts can be used for almost any task that needs executing. Its just a method of organisation. We then moved on to graphs. We talked about how they can be used to represent data. However, we also talked about how they can be used to intentionally mislead people. For example, a bar graph in a 3D view can be rather deceiving. A smaller bar can be made to look 'fatter' and on first glace it looks more prominent than the other taller bar. After this we talked about sequences and relations, which was translated to mean a set of ordered pairs. All throughout my history of mathematics I have always struggled to find patterns in maths. I may be fairly good at maths but when it comes to these kinds of problems I am horrible. Probably because I am a very visual learner. And numbers just don't supply any visual value for me. Andy told us to try and draw the patterns in different ways. I thought this would help but to no avail. Even still I gave me new perspective as to how I can view problems rather than just stopping when I hit a dead end.
We also were given isometric paper for us to draw on. I've done 4 years of graphics so this was nothing new to me as i don't really have issues visualizing 3D objects. The last exercise that we did was to try and fit 11 squares within a single square. I don't know why but I really had trouble with this, (although I only made 2 attempts). After Andy revealed the solutions I really felt stupid. It was really easy I just didnt think about my approach. I should have thought of the solution as 5+5+1 = 11. Make 1 big square and the rest smaller. Overall, once again I did not feel as though I benefited much from this lecture. I want to be doing more exciting things that have more relevance to me.
