Hexagonal structures are commonly found in nature, such as in honeycombs, because they are very strong yet allow for efficient use of space. Symmetry and specific facial ratios are thought to contribute to perceptions of attractiveness according to some research. Simple math errors can have large consequences, as seen with the Titanic disaster where not accounting for the different behaviors of its propellers when reversing contributed to its sinking.

3. Elementary Maths in nature
Honey combs are made up of multiple hexagonal
structures
it is one of the strongest structures in nature,
many man made structures are inspired from the
design,structure and strength of the honey comb.
Square would also work but it won't be as rigid as
hexagon .
Triangles would be strong but it would be hard to
extract honey back

5. Science of sex appeal using math
Psychologist Dr. Lisa DeBruine of the University of Aberdeen in Scotland says
she's found that female faces become more attractive to men when the
women are ovulating. "We think that the women might look healthier, have a
bit of a healthier glow when they are ovulating," Dr. DeBruine says.
6. Symmetry is another factor that determines a face's
attractiveness. Dr. Kendra Schmid, an assistant professor of
biostatistics at the University of Nebraska Medical Center, says
there is a equation for the "perfect" face. She uses 29 different
measurements to determine someone's appeal on a scale of 1
to 10.
Dr. Schmid says the ratio of the length of the face to the width of
the face should be 1.6, also known as the "golden ratio."
7. Whose face is the most "perfect," according to Dr.
Schmid's measurements? No big surprise here! highest

An article in the Sunday times in June 2004
revealed the fact that you cant even assume
that buying larger bags of exactly the same
pasta would work out cheaper
the newspaper found that the difference can be
as much as 30%. The supermarket chains
may be exploiting the assumption people
have that buying is cheaper. But if you work
out it out quickly in your head you'll never be
caught out

15. Simple math failure which led to the titanic
ship disaster
The Titanic had three steam-driven propellers,
with the outer two driven by piston engines and
the center screw driven by a steam turbine.
Steam turbines have the advantage of generally
being smaller and more efficient than their
piston counterparts, but have the drawback of
being one-way; that is, the steam can only flow
forward and the shaft can only turn in one
direction.
16. So when First Officer Murdoch slammed the big girl into
full reverse in order to avoid the iceberg, the outer two
screws started turning the other way, while the center
one just stopped .It sort of makes sense; if you're trying
to go backward, you don't want one of your propellers still
pushing you forward.However, the center screw was
directly in front of the rudder, and shutting it down meant
less water was washing over the rudder, which crippled
the ship's handling.Had the center prop been designed in
such a way that it kept turning in the event of a reversal
(or if they hadn't reversed at all), it's pretty likely the ship
would have missed the iceberg completely, saving the
lives of 1,514 people and eight dogs.
