Q & A
What is the Fibonacci sequence?
-The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. It goes 0, 1, 1, 2, 3, 5, 8, 13, and so on, continuing indefinitely.
How is the Fibonacci sequence generated?
-The Fibonacci sequence is generated by adding the last two numbers in the sequence. For example, starting with 1 and 1, the next number is 2 (1+1), then 3 (1+2), then 5 (2+3), and so on.
Why is the Fibonacci sequence significant in nature?
-The Fibonacci sequence is significant in nature because it appears in the arrangement of many natural structures, such as the spirals in galaxies, the pattern of seeds in sunflowers, and the branching of trees.
How does the Fibonacci sequence translate into physical geometry?
-The Fibonacci sequence translates into physical geometry by using squares whose sides are the Fibonacci numbers. These squares can be arranged to form larger patterns, such as spirals, which mimic natural forms.
What is the purpose of using graph paper when drawing the Fibonacci sequence?
-Using graph paper when drawing the Fibonacci sequence helps ensure that the squares are evenly and symmetrically placed with consistent measurements, which simplifies the process of creating accurate geometric representations.
How are the squares connected to form a Fibonacci spiral?
-The squares are connected by drawing lines that form perfect squares, with each subsequent square having a side length that is the next number in the Fibonacci sequence.
What is the role of circles in constructing the Fibonacci spiral?
-Circles are used to construct the Fibonacci spiral by drawing a circle that is divided into four equal parts by a cross, with each arm of the cross being the length of the current square. The spiral is then drawn within one quarter of this circle.
Why is the method of using circles to construct the spiral considered to closely match nature?
-The method of using circles to construct the Fibonacci spiral is considered to closely match nature because it replicates the organic, curving patterns found in natural phenomena such as the spirals in galaxies and the arrangement of leaves on a stem.
What is the significance of the cross when drawing the Fibonacci spiral?
-The significance of the cross when drawing the Fibonacci spiral is to ensure that the circle used for the spiral is properly aligned with the square, with each arm of the cross being the length of the square's side, ensuring that the spiral fits within the square.
How does the completed Fibonacci spiral relate to the twisting motions of a galaxy?
-The completed Fibonacci spiral relates to the twisting motions of a galaxy by mimicking the logarithmic spiral patterns observed in the arms of galaxies, which are believed to be influenced by the arrangement of stars and interstellar matter.

Transcripts
this is Gareth Manfred graph with
restore the planet and today I'm here to
share with you about the Fibonacci
sequence and spiral the Fibonacci
sequence is a series of numbers that go
from one to 1 to two to three to five to
8 and then to 13 and 21 and on and on in
fact it will continue like that forever
you might wonder is this some sort of
Arcane mathematics that doesn't make any
sense
absolutely not this number sequence is
very easy to understand you simply add
back the last two numbers for example we
start with one the smallest total unit
that we can have there's nothing before
one so we simply have to duplicate it so
we get another one but the next time we
perform this process we get one and one
which makes two to perform this process
again you'll have to add two and one to
produce three then two and three to
produce five then three and five to make
eight and eight and five to make 13 and
so on unto Infinity nature uses this
extraordinarily simple number sequence
to construct so many of her forms
everything from galaxies to sunflowers
and now I'm going to show you how this
number sequence translates into actual
physical geometry if you're just
starting out it's best to begin with a
surface like graph paper meaning that
it's easiest if you draw on something
that has evenly and symmetrically placed
square units of measurement that are all
of the same size to make it simple we'll
have one of these units represent one
and we'll trace it out in red then we
need another one unit so we'll draw that
one next to the first one then on the
top or in this case the bottom we can
can draw a line connecting both of the
two squares that we made we can then
duplicate that line three more times and
produce a perfect square then we can
duplicate that process as many times as
we like or as many times as the canvas
that we're using will allow and as you
can see the 5 square is 5 units by 5
units the 8 square is 8 units by 8 units
and so on now I'm going to show you how
to add the more feminite curving lines
there are various ways that I've seen
different artists do this but I'm going
to show you the method that I like the
best because I feel that it most closely
matches nature this method allows you to
use circles to construct the spiral to
begin with draw a perfect cross whose
every arm is the exact length of the
square that you're working in the center
of this cross should be placed furthest
from where the spiral will end up being
now all you've got to do is draw a
perfect circle which by virtue of its
size and positioning is cut into four
equal pieces by the cross this means
that the square that you're working on
should take up one quar of the circle
that you're using to produce a spiral
within it now all we've got to do is
erase the other 3/4 that we don't need
but in this case either side is the same
so we can simply add back in one quarter
now all we've got to do is repeat this
process again and again until all of the
zero curvature scaffolding for our
Fibonacci spiral is filled and as you
can see in its completed form it very
closely matches the twisting motions of
a galaxy thanks so much for watching and
wanting to understand our universe have
by far the absolute best day ever
