How good were you in Mathematics in schools
! : a²+b² =
(a+b)² - 2ab !! - how
much do you like Cabbage in your food ?
- the humble cabbage – encompasses several cultivars of Brassica oleracea, a
leafy green, red (purple), or white (pale green) biennial plant grown as an
annual vegetable crop for its dense-leaved heads. The word “cabbage” comes from the French word
caboche, which means “head.” That makes sense given the shape. And the metaphor
exists in English, where we talk about a head of cabbage.
Some
of its cousins are more interesting !! and tastier !!! - Cauliflower
is one of several vegetables in the species Brassica oleracea in the genus
Brassica. It is an annual plant that reproduces by seed. Typically, only the
head is eaten – the edible white flesh is sometimes called "curd"
(with a similar appearance to cheese curd). The cauliflower head is composed of
a white inflorescence meristem. Cauliflower heads resemble those in broccoli,
which differs in having flower buds as the edible portion.
Its much elitist cousin is - Broccoli an
edible green plant in the cabbage family
whose large flowering head, stalk and small associated leaves are eaten
as a vegetable. Broccoli is classified in the Italica cultivar group of the
species Brassica oleracea. Broccoli has large flower heads, usually dark green,
arranged in a tree-like structure branching out from a thick stalk which is
usually light green. The mass of flower heads is surrounded by leaves. Broccoli
resembles cauliflower, which is a different but closely related cultivar group
of the same Brassica species. It is
eaten either raw or cooked and is used in soups too.
Acharya Pingala was an
ancient Indian poet and mathematician, the author of the Chandaḥśāstra (also called the
Pingala-sutras), the earliest known treatise on Sanskrit prosody. Fibonacci (1170 – 1240) also known as Leonardo Bonacci, Leonardo of
Pisa, or Leonardo Bigollo Pisano was an Italian mathematician from the Republic
of Pisa, considered to be "the most talented Western mathematician of the
Middle Ages". The name he is commonly called, Fibonacci, was made up in
1838 by the Franco-Italian historian Guillaume Libri and is short for filius Bonacci ('son of
Bonacci').
Fibonacci
popularized the Indo–Arabic numeral system in the Western world primarily
through his composition in 1202 of Liber Abaci (Book of Calculation). He also
introduced Europe to the sequence of Fibonacci numbers,
which he used as an example in Liber Abaci.
In mathematics, the Fibonacci numbers, commonly denoted Fn , form
a sequence, the Fibonacci sequence, in which each number is the sum of the two
preceding ones. The sequence commonly starts from 0 and 1 - the first few
values in the sequence are:
0, 1,
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144.
The Fibonacci numbers were first described in Indian
mathematics, as early as 200 BC in work by Pingala on enumerating possible
patterns of Sanskrit poetry formed from syllables of two lengths. They are
named after the Italian mathematician Leonardo of Pisa, later known as
Fibonacci, who introduced the sequence to Western European mathematics in his
1202 book Liber Abaci.
Romanesco broccoli is an edible flower bud of the
species Brassica oleracea, which also includes regular broccoli and
cauliflower. It is chartreuse in color, and has a form naturally approximating a
fractal. Romanesco broccoli has a nutty flavor and a firmer texture than
regular broccoli when cooked.
The
Romanesco superficially resembles a cauliflower, but it has a visually striking
fractal form. It is chartreuse in color, with the form of a
natural fractal. Nutritionally, romanesco is rich in vitamin C, vitamin K,
dietary fiber, and carotenoids. The
inflorescence (the bud) is self-similar in character, with the branched meristems making up a logarithmic spiral,
giving a form approximating a natural fractal; each bud is composed of a series
of smaller buds, all arranged in yet another logarithmic spiral. This
self-similar pattern continues at smaller levels. The pattern is only an
approximate fractal since the pattern eventually terminates when the feature
size becomes sufficiently small. The number of spirals
on the head of Romanesco broccoli is a Fibonacci number.
Interesting ! - some photos of Romanesco broccoli taken from twitter.
