LEARNING LOG 1: Observe, Connect and Reflect on Your Learning
To gaze is to think. Salvador Dali
PART I – Concepts in Symmetry
Period

Question
Your Observations
(20 - 30 words) (2 marks)
Describe the symmetry of the Viking shield.
The rotational angle is 360°/4 = 90°
There are 4 mirror lines whereby 2 are unique.

What was the most surprising or interesting fact you learnt from
Week 1 lectures
Surprising fact was that I realized almost most objects around us have reflection and rotation operations and I wasn’t aware of it all these years, till I learnt it recently
(20 - 30 words) (2 marks
Describe the symmetrical elements you see in this
Japanese embroidery.
No mirror lines; 3-fold rotation (triad); point symmetry is 3 whereby the rotational angle is 360°/3 = 120°)

Can you add anything to your Week 1 description of the Viking shield?
There is a 4-fold rotation (tetrad).

You can’t criticize geometry. It’s never wrong. Paul Rand
PART II – Plane (2D) and Space (3D) Symmetry

Question
Your Observations
(up to 40 words) (2 marks)
Use the formal descriptors of plane symmetry to describe this bathroom tile tessellation. This is a p4mm (No.11)
The tile has Mirror lines, glide lines, 2-fold rotation and 4-fold rotation

Image 3
(up to 20 words) (2 marks)
How are you now more observant of symmetry in your surroundings? Use examples. I now notice that most of the things around us are symmetric. For example, observed the bricks of my HDB house are c2mm (No.9).

The triangle in Image 4 is weird. Was Paul Rand correct – geometry is never wrong?
Paul Rand is right. Geometry is never wrong but art can deceive. Artist can
