Historical Antecedents of Science and Technology Flashcards
Science
➢ Derived from the Latin word:
o Scientia -
means
Knowledge
It is described as “A discovery of regularity in
nature (principles and law of natural
phenomena)” – J. Heilbron (2003)
→ This pertains to the explanation or the
study about our physical world.
Science
It is defined as a systematized body of
knowledge based on facts, observation, and
experimentation.
→ There should be a system of acquiring
knowledge by following the scientific method.
SCience
Technology
➢ Derived from the Greek word:
o Techne or techno –
means
Art or skil
It is the application of scientific knowledge.
Technology
it indeed play a major role in
everyday life.
Science & Technology
most significant development in science and
technology.
o It is the most significant since people
need to go from one place to another
(e.g., trading of goods in the ancient
times)
Transportation
to go places and discover new horizons.
➢ for food and to find better locations to
settle.
➢ to trade their surplus goods in exchange
for the things they lacked.
Transportation
assisted them in their journeys.
o Example: the discovery of the
development of maps, compass,
GPS, and satellites to monitor the
places na pupuntahan natin.
- Navigation
to facilitate trade and prevent possible conflicts.
o It is important na nagkakaintindihan
sila so starting from their own
development of their own language
until they learn the language of
others.
Communication
to remember the places they had been to.
➢ to document the trades they made.
➢ so they could establish their identities as they
tried torelate with other culturesand civilizations.
o Another important part in our history
is record keeping so that the different
technologies they used, learnings,
knowledge, and discoveries will be
recorded
Record Keeping
number of nations = demand for food and
necessities
➢ people need to produce their needs using limited
resources.
- Mass Production
➢ use of weapons and armors (development of
these are considered as their major
achievements).
➢ to prevent common conflicts especially in
different groups or cultures.
- Security and Protection
“conservation of life” (pertaining to health and
medicine)
Health
given this predicament, science and technology
played a major role in discovery of cures and
prevention of illnesses.
Health
➢ focuses on the construction (transportation,
establishments for protection, different
infrastructures).
➢ addresses their specific needs and wants.
- Engineering
by combining soot from wood smoke and
animal fat, thickened with gelatin from skins or different
chemicals to produce inks of different colors. It must withstand
the elements of nature and tamper proof.
Ink
The study and practice of making maps.
Cartography
Anaximander was the first of the ancient Greeks to draw a map
of the known world and as such he is considered to be one of
the first cartographers.
Cartography
Inventor/s: Ancient Egyptians
For writing purposes: Important because it was use for record
keeping (most common)
Papyrus
Functions:
- Metal shaping
- Agriculture
- Milling = to grind grain
Water/Wind Mill
Function: indicates the time of the day and for the sake of hemicycle, it specifies seasons as well as the time of day.
Sundial
2000 years old Earthquake Detector: Invented by Chinese
astronomer Zhang Heng in 132 AD.
Doomwatch dragons
-used to protect the skin from the sun (kohl was believed
to
repel flies and ward off infections, among other things)
-offer protection against evil (eyes without makeup
were thought to be vulnerable to the evil Eye)
Egyptian Eye
Makeup/KOHL
Inventor: Johannes Gutenberg
Function or Purpose:
● To address the need for publishing books that would spread
information to many people at a faster rate
● Also made works accessible to individuals who could not even
write
Printing Press
inventor: Ancient Chinese Alchemist
Around 850 AD, ancient Chinese alchemist were
experimenting with potassium nitrate, charcoal, and sulfur, as
they were trying to find
a potion for immortality but ended up creating an explosion. It
was initially used for
fireworks before used in warfare.
Gunpowder
Inventor: Alessandro Della Spina
Function or Purpose:
● The ground quartz magnifying lenses could help people with ong and
short sight
* Used for the treatment of Myopia in the Middle Age
Eyeglasses
Inventor: Zacharia Janssen
Function or purpose: Humans can see smallest things as wide as
a hair, suddenly we
saw a new world of living things in our water in our food and etc
Microscope
Paper bills were first used by the Chinese, who started carrying
folding money during the Tang Dynasty (A.D. 618-907) — mostly
in the form of privately issued bills of credit or exchange notes.
They made paper money because their devalued coins were
becoming too heavy to carry.
Paper Money
Inventor: Liutprand (French Monk - 8th Century AD)
Function or Purpose:
● Used to measure the passage of time
● It was ideal for ocean travel because the bobbing
waves didn’t affect its accuracy
Hourglass
Inventor: Shu Han, Zhuge Liang
Function or purpose: Wheelbarrow is designed to be pushed and
guided by a single
person using two handles to the rear or a sail may be used to
guide the ancient
wheelbarrow by wind. The modern user of the wheelbarrow lifts
up the handles and
pushes the device forward, using the wheel to lighten the load.
Wheelbarrows may be
used to transport garden soil.
Wheelbarrow
Inventor: James Hargreaves
Function or purpose:
Early machine for turning fibre into thread or yarn which also
symbolizes freedom for the Indian people.
Spinning wheel
Invention: Light-emitting Diode
Inventor: Nick Holonyak invented the first visible LED light (color
red) in 1962
Function / Purpose: It is a semiconductor device made up of
gallium arsenide phosphide that emits visible light when an
electric current passes through it. The output can range from
red to blue-violet according to its wavelength.
LED Light
Inventor: Raymond Vahan Damadian
Function or Purpose: Radiologic way of forming images of the
anatomy and physiological processes of the human body in both
health and disease.

The idea of the credit card came to Frank McNamara in 1949
while he was having dinner at a restaurant in New York City.
When it was time to pay the bill, McNamara realized he had
