Lesson 2: Historical Antecedents of Science and Technology Flashcards
It is defined as a precursor to the
unfolding or existence of something.
ANTECEDENTS
\_\_\_ of science and technology are factors that paved way for the presence of advanced and sophisticated scientific and technological innovations today
Antecedents
We can use the _____
of science and technology to come up
with proper decisions and applications
of science and technology to daily life.
historical developments
The historical antecedents of science and
technology is divided into three major eras:
the ancient, the middle age and the modern age.
They paved the way for
advances in science and technology.
Ancient civilization
These advances during the ancient
period allowed civilizations to
flourish by finding better ways of
communication, transportation,
self-organization and ways of living
People from ancient civilization used
____ as means of transportation long
before the invention of the wheel
animals
Ancient wheel grew out from a mechanical device
called the
“potter’s wheel” – a heavy
flat disk which is spun horizontally on
an axis.
The Sumerians invented the potter’s
wheel after
3500 BC thus, the invention
of the wheel is credited to them.
Around 3000 B.C., the ancient
Egyptians began writing on
a papyrus, a
material similar to a thick paper
Papyrus is made up of the
pith of the plant called Cyperus papyrus.
Before the invention of the papyrus,
writing was done on stones
With the invention of the paper,
record-keeping and documentation became efficient,
wide-spread and vast which also hastens
information dissemination during those
times.
A tool used and invented by ancient
Egyptians to irrigate land.
SHADOOF
It is a hand-operated device used for
lifting water.
SHADOOF
Its invention introduced the idea
of lifting things using counterweights
Discovered in 1902 and retrieved from
the waters of Antikythera, Greece.
ANTIKYTHERA MECHANISM
It is a mechanism similar to a clock for
it has a circular face and rotating hands.
ANTIKYTHERA MECHANISM
It is believed that this mechanism is
used to predict astronomical positions
and eclipses.
ANTIKYTHERA MECHANISM
It is believed that this mechanism is the
oldest known antecedent of modern
clockwork invented By
Greek scientists 150-100 BC.
Is also known as the Hero’s engine
and is believed to be the antecedent of
the modern steam engines.
AEOPILE
It is a steam-powered turbine which
spins as the water container at its center
is heated
AEOPILE
At first, it doesn’t serve any practical
purpose. It is believed to be one of the
“temple wonders” at that time
AEOPILE
The major advances in scientific and
technological development took place in
this period, the middle ages.
THE MIDDLE AGE
These advancements include constant increase if new inventions, innovations in traditional production and the emergence of scientific thinking and method.
THE MIDDLE AGE
Perhaps one of the most important
technological innovations during the
middle ages is the invention
of the
HEAVY PLOUGH
Because of the invention of it, northern Europe saw rapid economic prosperity
HEAVY PLOUGH
According to Thomas Andersen of the
University of Denmark,
“The heavy plough turned European agriculture and economy on its head. The fields with heavy, fatty soil became those that gave the greatest yields.”
Around 850 A.D., Chinese alchemists
accidentally invented the
GUNPOWDER
Prior to the invention of gunpowder,
swords and spears were used in battles
and wars.
The invention of gunpowder has
allowed
advanced warfare such as fiery
arrows, cannons and grenades.
I was first used by Chinese
in 17th century.
PAPER MONEY
Before the introduction of paper money,
merchants and traders used
precious
metals such as gold and silver.
The use of these paper many ease the
burden of merchants and traders
because
it is easier to transport compared to
other currencies
The development of it
helped the people in accurately keeping
the track of time
MECHANICAL CLOCK
The sophistication of clockwork
technology drastically changed the way
of spending the day and work patterns
were established
A machine used to transform fiber into
thread or yarn and eventually woven
into cloth
SPINNING WHEEL
It is theorized that the ___ are the
one invented the spinning wheel
between 6th and 11th century.
Indians
It sped up the rate of manually spinning
fiber by 10 to 100 times
SPINNING WHEEL
Historical period when people realized
the importance of the efficiency of transportation, communication and production.
THE MODERN AGE
Industrialization took place but with
greater risk on human health, food
safety and environment
THE MODERN AGE
Invented by a Dutch Zacharias
Janssen in 1590’s
Together with his father, they try to
experiment by putting several lenses on a tube
COMPOUND MICROSCOPE
This led to a discovery that an object
placed at the end of the tube can be magnified larger
compared to a simple magnifying lens.
COMPOUND MICROSCOPE
His invention was an important
progression to the
compound microscope which we are
using nowadays
Dutch Zacharias
Janssen
Invented by Galileo Galilei that can
magnify 20 times larger than a regular
glasses
TELESCOPE
It is one of the most important invention
in the study of ___ during the
modern age
astronomy
Galileo’s discovery made clear that
the universe is far larger than they imagine
Built by French weaver Joseph Marie
Jacquard
JACQUARD LOOM
simplifies textile manufacturing.
JACQUARD LOOM
Prior to this invention, a draw loom is used which requires two persons to operate. This invention can be operated by one person which further simplified textile manufacturing
JACQUARD LOOM
The engine powered airplane Invented and designed by
Wright brothers, Orville Wright and Wilbur
Wright
They demonstrated that slightly-tilted
wings are the key features of a powered
aircraft.
Wright brothers, Orville Wright and Wilbur
Wright
Their discovery paved way to the
comprehensive understanding of the
aerodynamics and how aircraft wings
work
engine powered airplane
TV was Invented by
Scottish engineer John
Logie Baird in 1920s.
He televised objects in outline in 1924,
human faces in 1925, moving objects in
1926 and colored images in 1928.
Scottish engineer John
Logie Baird in 1920s.
British Broadcasting Corporation used
this for its earliest television
programming in 1929
television
This first television is
mechanical and
not the same as the television we have
nowadays
The e-jeepney was first introduced in
Manila And Bacolod City
The e-jeepney is the inventive response
to the problem caused
by traditional
jeepney such as noise and air pollution.
E-jeepney are designed to be
environmental friendly, eliminating
noise and air pollution as they run on
electricity
Invented by Ilonggo scientist
Abelardo Aguilar out of strain of
bacterium Streptomyces erythreus.
ERYTHROMYCIN
It is an anti-biotic which prevents the
growth of bacteria and prevent infection
ERYTHROMYCIN
A world-renowned Filipino pediatrician
and national scientist Fe Del Mundo is credited for the invention of the
MEDICAL INCUBATOR
She is also credited for inventing the
medicine for jaundice.
Fe Del Mundo
It addresses the needs of the rural communities of the Philippines without electricity which needs aid in regulation of body temperature among newly-born babies
MEDICAL INCUBATOR
Rolando Dela Cruz is credited for the
invention of a product that can remove
unwanted moles and warts from the
skin.
MOLE REMOVER
This mole-removal method doesn’t need
surgical procedures.
MOLE REMOVER
His commercial product invention made
use of extract of cashew nuts
(Annacardium occidentale) which is
very common in the Philippines.
MOLE REMOVER
His invention is also highlighted for its
accessibility, affordability, and painless
and scarless procedure
MOLE REMOVER
A Filipino food technologist, Maria
Orosa, invented this variety of catsup
out of bananas
BANANA CATSUP
BANANA CATSUP was invented this during
World War II as there was a shortage of tomatoes during that time
This variation of catsup has a
brownish-yellow color but dyed with red
to resemble catsup’s original color
