Okay, here are the steps to find the 16th term:
1) 12th term is given as 144
2) 10th term is given as 55
3) 11th term is 144 - 55 = 89
4) 14th term is 89 + 144 = 233
5) 15th term is 144 + 233 = 377
6) 16th term is 233 + 377 = 610
So, the 16th term of the Fibonacci sequence is 610.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

13. The Elephant and the blind
men by James Baldwin
There were once six blind men who stood by the
road-side every day, and begged from the people who
passed. They had often heard of elephants, but they
had never seen one; for, being blind, how could they?
It so happened one morning that an elephant was
driven down the road where they stood. When they
were told that the great beast was before them, they
asked the driver to let him stop so that they might see
him.
14. The Elephant and the blind
men by James Baldwin
Of course they could not see him with their eyes; but
they thought that by touching him they could learn
just what kind of animal he was.
The first one happened to put his hand on the
elephant's side. "Well, well!" he said, "now I know all
about this beast. He is exactly like a wall."
The second felt only of the elephant's tusk. "My
brother," he said, "you are mistaken. He is not at all
like a wall. He is round and smooth and sharp. He is
more like a spear than anything else."
15. The Elephant and the blind
men by James Baldwin
The third happened to take hold of the elephant's
trunk. "Both of you are wrong," he said. "Anybody
who knows anything can see that this elephant is like
a snake."
The fourth reached out his arms, and grasped one of
the elephant's legs. "Oh, how blind you are!" he said.
"It is very plain to me that he is round and tall like a
tree."
The fifth was a very tall man, and he chanced to take
hold of the elephant's ear. "The blindest man ought
to know that this beast is not like any of the things
that you name," he said. "He is exactly like a huge
fan."
16. The Elephant and the blind
men by James Baldwin
The sixth was very blind indeed, and it was some time
before he could find the elephant at all. At last he
seized the animal's tail. "O foolish fellows!" he cried.
"You surely have lost your senses. This elephant is not
like a wall, or a spear, or a snake, or a tree; neither is
he like a fan. But any man with a par-ti-cle of sense
can see that he is exactly like a rope."
Then the elephant moved on, and the six blind men
sat by the roadside all day, and quarreled about him.
Each believed that he knew just how the animal
looked; and each called the others hard names
because they did not agree with him. People who
have eyes sometimes act as foolishly.
17. The Elephant and the blind
men by James Baldwin
To work mathematically, you need to smell the whole
elephant, hear its roar - and take pleasure in its
beauty, strength and also its surprising grace
and subtlety. And if we don't want to scare the
children? Well, who can resist a baby elephant?

19. 15 Incredible Examples of Mathematics in Nature
1. Snowflakes
The tiny but miraculous
snowflake, as an example of
symmetry in nature, exhibits six-
fold radial symmetry, with
elaborate, identical patterns on
each arm.
Snowflakes form because
water molecules naturally
arrange when they solidify. It’s
complicated but, basically, when
they crystallize, water
molecules form weak hydrogen
bonds with each other.
1. Sunflowers
Bright, bold and beloved by
bees, sunflowers boast
radial symmetry and a type
of numerical symmetry
known as the Fibonacci
sequence, 1, 2, 3, 5, 8, 13,
21, 24, 55, and so forth.
Scientists and flower
enthusiasts who have taken
the time to count the seed
spirals in a sunflower have
determined that the amount
of spirals adds up to a
Fibonacci number.
20. 15 Incredible Examples of Mathematics in Nature
1. Uteruses
According to a gynaecologist,
doctors can tell whether a uterus
looks normal and healthy based on
its relative dimensions – dimensions
that approximate the golden ratio.
When women are at their most
fertile, the ratio of uterus length
to its width is 1.6. This is a very
good approximation of the golden
ratio
1. Nautilus Shell
A nautilus is a cephalopod
mollusk with a spiral shell
and numerous short tentacles
around its mouth. Although
more common in plants, some
animals, like the nautilus,
showcase Fibonacci numbers.
A nautilus shell is grown in a
Fibonacci spiral. The spiral
occurs as the shell grows
outwards and tries to
maintain its proportional
shape.
21. 15 Incredible Examples of Mathematics in Nature
1. Romanesco Brocolli
Romanesco broccoli has an
unusual appearance, and
many assume it’s another
food that’s fallen victim to
genetic modification. However,
it’s actually one of many
instances of fractal
symmetry in nature. In
geometric terms, fractals
are complex patterns where
each individual component has
the same pattern as the
whole object. In the case of
romanseco broccoli, the entire
veggie is one big spiral
composed of smaller, cone-
like mini-spirals.
1. Pinecones
Pinecones have seed pods that
arrange in a spiral pattern.
They consist of a pair of
spirals, each one twisting
upwards in opposing directions.
The number of steps will
almost always match a pair of
consecutive Fibonacci numbers.
For example, a three–to–five
cone meets at the back after
three steps along the left
spiral and five steps along the
right. This spiralling Fibonacci
pattern also occurs in
pineapples and artichokes.
22. 15 Incredible Examples of Mathematics in Nature
1. Honeycombs
Honeycombs are an example of
wallpaper symmetry. This is
where a pattern is repeated
until it covers a plane. Other
examples include mosaics and
tiled floors.
Mathematicians believe bees
build these hexagonal
constructions because it is the
shape most efficient for storing
the largest possible amount of
honey while using the least
amount of wax. Shapes like
circles would leave gaps
between the cells because they
don’t fit perfectly together.
1. Tree Branches
The Fibonacci sequence is so
widespread in nature that it
can also be seen in the way
tree branches form and split.
The main trunk of a tree will
grow until it produces a branch,
which creates two growth
points. One of the new stems
will then branch into two,
while the other lies dormant.
This branching pattern repeats
for each of the new stems.
23. 15 Incredible Examples of Mathematics in Nature
1. Milky Way Galaxy
Symmetry and mathematical
patterns seem to exist
everywhere on Earth – the
Milky Way Galaxy was
discovered, and, by studying this,
astronomers now believe the
galaxy is a near-perfect mirror
image of itself.
Having mirror symmetry, the
Milky Way has another amazing
design. Like nautilus shells and
sunflowers, each ‘arm’ of the
galaxy symbolises a logarithmic
spiral that begins at the
galaxy’s centre and expands
outwards.
1. Faces
Humans possess bilateral symmetry.
Faces, both human and otherwise, are rife with examples of
the Golden Ratio. Mouths and noses are positioned at golden
sections of the distance between the eyes and the bottom
of the chin. Comparable proportions can be seen from the
side, and even the eye and ear itself, which follows along a
spiral. For example, the most beautiful smiles are those in
which central incisors are 1.618 wider than the lateral
incisors, which are 1.618 wider than canines, and so on.
24. 15 Incredible Examples of Mathematics in Nature
1. Orb Web Spiders
Orb web spiders create
near-perfect circular webs
that have near-equal-
distanced radial supports
coming out of the middle and
a spiral that is woven to
catch prey. Orb webs are
built for strength, with
radial symmetry helping to
evenly distribute the force
of impact when a spider’s
prey makes contact with the
web. This would mean there’d
be less rips in the thread.
1. Crop Circles
Crop circles are a sight to
behold because they’re so
geometrically impressive.
A study conducted by
physicist Richard Taylor
revealed that, somewhere in
the world, a new crop circle
is created every night, and
that most designs
demonstrate a wide variety
of symmetry and
mathematical patterns,
including Fibonacci spirals and
fractals.
25. 15 Incredible Examples of Mathematics in Nature
1. Starfish
Starfish or sea stars belong to
a phylum of marine creatures
called echinoderm. Other
notable echinoderm include sea
urchins, brittle stars, sea
cucumbers and sand dollars.
The larvae of echinoderms have
bilateral symmetry, meaning
the organism’s left and ride
side form a mirror image.
Sea stars or starfish are
invertebrates that typically
have five or more ‘arms’. These
radiate from an indistinct disk
and form something known as
pentaradial symmetry.
1. Peacocks
The peacock takes the
earlier principle of using
symmetry to attract a
mate to the nth degree.
Male peacocks utilise their
variety of adaptations to
seduce sultry peahens.
These include bright colours,
a large size, a symmetrical
body shape and repeated
patterns in their feathers.

1. Sun-Moon Symmetry
The sun has a diameter of 1.4
million kilometres, while his
sister, the Moon, has a meagre
diameter of 3,474 kilometres.
With these figures, it seems
near impossible that the moon
can block the sun’s light and
give us around five solar
eclipses every two years.
29. Fibonacci, also called Leonardo Pisano,
English Leonardo of Pisa, original name Leonardo
Fibonacci, (born c. 1170, Pisa?—died after
1240), medieval Italian mathematician who
wrote Liber abaci (1202; “Book of the Abacus”),
the first European work on Indian and
Arabian mathematics, which introduced Hindu-
Arabic numerals to Europe. His name is mainly
known because of the Fibonacci sequence.
HISTORY
30. Fibonacci Sequence, (1,1,2,3,5,8,13,21, 34…) each number from the
sequence is the sum of the two numbers that precede it. Is strongly related
to the Golden Ratio ( = 1.618). First introduced by an Italian Mathematician
Leonardo Pisano Bigollo also known as Fibonacci in the year 1202.
Fibonacci observed numbers in nature. His most popular contribution
perhaps is the number that is seen in the petals of flowers.

•In mathematics and the arts, two quantities are in the golden ratio if the
ratio between the sum of those quantities and the larger one is the same
as the ratio between the larger one and the smaller.
• In this case, we refer to a very important number that is
known as the golden ratio.
• The golden ratio is a mathematical constant
approximately 1.6180339887.

47. THE GOLDEN RATIO
Putting it as simply as we can (eek!), the
Golden Ratio (also known as the Golden
Section, Golden Mean, Divine Proportion
or Greek letter Phi) exists when a line is
divided into two parts and the longer part
(a) divided by the smaller part (b) is equal
to the sum of (a) + (b) divided by (a), which
both equal 1.618.
