Mini Appendix of Off Season 2（extra ２）～ 

"What's the Golden Angle?"

1.  Now, welcome to the Grand Corridor.

It is a magnificent road, isn't it?

This time, let's talk about the Golden Angle.

The golden ratio is well known, but the golden angle is also more or less well known. 

It is known as the regularity of angles, which is mainly seen in the way leaves are arranged on plants.

When the circumference of a circle is divided by the ratio of 1 to Φ, that is, when the entire circumference is 1 + Φ, the central angle corresponding to the 1 part is called the golden angle, and is said to be about 137.5 degrees (Figure 1).

( Fig. 1 )

2.  Even though it is said to be a regularity of plant leaves, the reason why it is so is not clear to us,

So everyone says.

“Wow, that's interesting!”

“I didn't know that!”

.....But let's think about it carefully.

If you think about it, the circumference of a circle is 1 + Φ,
Φ = 1 + 1/Φ,
One circumference is 1/Φ + 2

So, one full circle can also be written as 1/Φ + 2.

Now, the circle corresponding to this “1” is 137.5°.
Corresponding to 1/Φ is approximately 85°.

Given a triangle whose bottom two angles are each 1/Φ (0.618033988), the angle at the vertex is,
(1 + φ)/2 - 2/Φ, which is approximately 0.072949018, or about 10° in angle.

( Fig. 2 )

This is a very sharp angle, but if we measure the angle of the wall of the Grand Corridor of the Pyramid, it would be something like this.

The inclination of the Grand Corridor is well known, but the angle of the walls is not so well known.

It is not a straight slant, but rather, as it gets higher and higher, it seems to be gradually pushed into the center of the corridor.

Of course, this is Tanu-chan's imagination!

It's totally my delusion!




3.   Now, why did they use such an extremely sharp angle?

 Any Hints?

.... Oh, there is a building in NYC with similar angles!

( Fig. 3 )

No way!!

.......I guess I'm overthinking it!


Well, that's all for today.

I'm not sure if there will be more stories to come about the Golden Angle.
