Hi there Maths people or with an interest in maths

I have just read Eddy Woos book “Wonderful World of Maths ” PanMcMillan 2018

I really enjoyed the Chapter 07 ” What Sunflowers know about the Universe ”

Here Eddy talks about the Golden Ratio .  This is the term phi  Φ  which equals ( to 10 significant figures ) Φ = 1.6180339887  or  (1+√5)/2 or the larger root of  y=x^2 -x-1    or  (a+b)/b = b/a  from a linear term ( need to insert graphic to see this more )

Cant see how to insert image here , get to that later . I will now see how this post looks on Andriod Oreo V8

Bye for now . Just seen the image above 🙂
