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.”
