  1. The Golden Ratio By Akshat Rajan

  2. What is Golden Ratio? • The golden ratio is an irrational number. If a person tries to write it, they will never stop and never be the same again and again, but it will start this way- 1.6180339887...(approximately) An important thing about this number is that a person can subtract 1 from it or divide 1 by it. Either way, he will find the same number. Math is related to everything. In this presentation you will learn how its related to beauty. You can call somebody beautiful using math too. The golden ratio is 1:1.6.

  3. MY FACE Bridge Width=15mm Eye Width=14 mm Bridge/Eye Ratio=15:14 Mouth Width=18mm Teeth Width=16mm Mouth/Teeth Ratio=9:8 The 2 ratios are not same but are a bit close.

  4. Comparing Faces (9 classmates)

  5. Class Mates • Total B/E Ratio=66:60 • Average=11:30 • Total M/T Ratio=120:78 • Average=20:13 • These ratios were mostly different but a few were similar.They were little different. The average is 20:13. In one, Nishna’s its exact the others are similar but not all.

  6. Adult Face My Mom Bridge Width=15mm Eye Width=14 mm Bridge/Eye Ratio=15:14 Mouth Width=18mm Teeth Width=16mm Mouth/Teeth Ratio=9:8

  8. The result is not that different. • My moms and the actresses aren't far apart! So maybe because my mom is beautiful.

  9. In Nature • Ancient Greek- Partheron

  10. IN THIS STAMP, This stamp is proportional! It is exactly made according to the golden ratio!

  11. This is the sunflower which is in the golden ratio! When it’s a simple fraction The pattern of seeds are spirals.

  12. Many Paintings too! Her face is exactly the golden rectangle!! the ratio of the width of her forehead compared to the length from the top of her head to her chin. So math is even used while making a painting! (Interdisciplinary)

  13. The human body!! • We have 2 eyes 2 pairs of limbs, a nose etc. All these parts can also be divided up in terms of the golden ratio! So imagine the amount of things with math behind it. This power point simply proves the math is everywhere, even when we don’t want to be there, its THERE!!

  14. Places like the Pyramid of Giza, the UN building in New York! Are also in golden ratio! Every 10 floors are in the golden ratio! Math even comes in Architecture!

  15. Reflection • I think this investigation was very essential it actually showed us how math is ‘the’ most important subject in our lives. Even if we hate it, its there and if we don’t learn now we will never! So I think this investigation was beyond ratio and proportion as it explained the importance and significance of math and all the different parts of it like ratio! I did not have any difficulties in this but was a bit confused. This is related to our AOI Human Ingenuity as golden ratio is created by us!
