Math Art Project Reflection

Sorry for missing this art project reflection.  The image shown above is the our replica of Mergerate’ art work which is the work we investigate in this project. I would like to thank my group member Kyle for setting up the project on LaTeX. Then we finished coding as a group. In this work, the triangular grids are numbered sequentially beginning with 1 at the centre and continuing outward along a spiral path to 486 at the far left. A triangle is coloured cyan if it is prime, magenta if it is a happy number, and yellow if it is a triangular numbers. The Fibonacci number is represented as a transparent white triangles layered on top. A blended colour is used for integers belonging to more than one sequence.  Following is our extended art work. After group discussion, we decided to include perfect squares and lucky numbers in our extended art work.  We found that the perfect squares produced an interesting "spiral galaxy" pattern with 5 arms that was sim...

The scales puzzle

By -
My first though is to figure out 4 numbers from 1 to 40 that can be added together to obtain any whole numbers from 1 to 40. So, one of the 4 weights must be 1g, which is the smallest weight. Should the next be 2g? There is only one whole number can be obtained by combining 1g and 2g, which is 3g. What about 3g? The combinations of 1g and 3g give us 2 whole numbers, which are 2g (3g-1g) and 4g (1g+3g). What about 4g? But any combination of 1g and 4g won't give me 2g. Now, 1g and 3g are the two of the 4 weights in my mind. And using a similar pattern, I figure out 9g is one of the 4 weights: Combination of 1, 3, 5: 3-1=2 3+1=4 5-1=4 5-3=2 Obviously, 5g is not a choice since numbers obtained by combining 1,3 and 5 can be obtained by combinations of 1 and 3 as well. New numbers produced by combining 1, 3 and 6 6-1=5 6+1=7 6+3+1=10 Now we have 1,2,3,4,5,6,7 and 10 New numbers produced by combining 1, 3 and 7 7+3=10 7-1=6 7+1=8 7+3+1=11 7+3-1 7+1-3 Now we have 1...
