Keywords

💡Scientific Revolution

The Scientific Revolution refers to the period from the 16th to the 18th century during which there was a significant transformation in scientific ideas and methodologies. It marked the shift from religious authority to scientific authority and laid the groundwork for modern science. In the video, the Scientific Revolution is highlighted by the work of figures like Copernicus, Kepler, and Galileo, who challenged the geocentric model and introduced the heliocentric model of the solar system.

💡Heliocentrism

Heliocentrism is the astronomical model that positions the Sun at the center of the universe with the Earth and other planets revolving around it. This concept, introduced by Copernicus, was a radical departure from the then-accepted geocentric model and is a cornerstone of the Scientific Revolution discussed in the video.

💡Empiricism

Empiricism is a philosophical approach to knowledge that emphasizes experience and observation, particularly through the senses, as the primary source of knowledge. In the video, Francis Bacon is mentioned as a pioneer of empiricism, advocating for the scientific method that relies on systematic observation and experimentation, which is central to the Scientific Revolution.

💡Rationalism

Rationalism is a philosophical view that emphasizes the role of reason and logic in acquiring knowledge, often in contrast to empirical evidence. Rene Descartes, referred to in the video, is a key figure associated with rationalism, distinguishing between knowledge derived from reason alone and that which requires experience.

💡Scientific Method

The Scientific Method is a systematic approach to investigation that involves observation, hypothesis formulation, experimentation, and the collection and analysis of data. It is a central theme in the video, illustrating the shift towards evidence-based knowledge during the Scientific Revolution and the establishment of a structured approach to scientific inquiry.

💡Universal Gravitation

Universal Gravitation is the physical phenomenon that attracts all objects with mass towards one another, as described by Isaac Newton. In the video, Newton's formulation of the laws of motion and universal gravitation is highlighted as a unifying theory that built upon the work of Copernicus, Kepler, and Galileo, significantly influencing the Scientific Revolution.

💡Industrial Revolution

The Industrial Revolution refers to the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. It marked a shift from agrarian, rural societies to industrialized, urban ones. The video discusses the Industrial Revolution as the second wave of technology, characterized by the invention of machinery, the rise of factories, and significant changes in work and society.

💡Information Revolution

The Information Revolution is a period during which there was a significant shift from traditional computing and information processing techniques to those based on digital electronics and communication.

hi everyone

welcome to the second chapter of this

sts course i am ian de la cruz

and this is the first part of this

chapter the scientific revolution

and to give you a head start of this

topic please watch and enjoy

this short video

during this times scientific authority

began to displace religious

authority and several disciplines

considered as legitimate at that time

such as alchemy and astrology

lost scientific credibility the

scientific revolution

laid the foundations for the age of

enlightened by the power of sea faders

and circumnavigation lands that were

previously unknown to europe

were discovered also the invention of

printing machines

brought the proliferation of new

information across the different regions

of the old world while the dates of the

scientific revolution are disputed the

copernican theory

of heliocentrism marks the beginning of

scientific revolution

nicolas copernicus argued that indeed

earth

the stars and other planetary bodies

revolve around the sun

contrary to the widely accepted

geocentric system

at that time johannes kepler has then

continued the theory and developed the

loss of planetary motion

one of these laws showed that the

planets revolve around the sun in

elliptical orbits instead of circular

galileo galilei came after and developed

his own telescope with enough

magnification to allow him study the

planet venus

and the faces of the moon galileo's

findings threatened the religious

leaders

because they went against the church

teachings and authority

later on galileo stood before the court

and knelt before the cardinals

under the threat of torture during the

scientific revolution

the value of evidence through

experimental method

led towards a scientific methodology in

which

empiricism has played a huge role

[Music]

one pioneering founder of empiricism is

francis bacon

described as the empiricist and

established the inductive methodologies

or simply called as the scientific

method other hand

another founder described as the

rationalist is rene descartes whom

distinguished between the knowledge that

could be attained by reason alone

such as mathematics and the knowledge

that required experience of the world

like physics under the scientific method

both natural and artificial

circumstances were abandoned

and the research tradition of systematic

experimentation was slowly accepted

throughout the scientific community

these were body of techniques for

investigating phenomena

through acquiring new knowledge or

correcting and integrating previous

knowledge

systematic observation measurement

formulation

testing and modification of hypotheses

an application of empirical or

measurable evidence

subject to specific principles of

reasoning to attain a strong and

concrete answer

now going back to the revolutionary

views of copernicus

kepler and galileo isaac newton brought

together

their breakthroughs under a single

theory of motion

newton has also formulated the universal

gravitation which dominated

almost all the scientist view of the

physical universe

including the principles that account

for the trajectories of comets

tides and precessions of the equinoxes

newton's key figure during the

scientific revolution

made himself acknowledge the works of

previous great minds before him

since then scientific revolution went

viral

to various fields and disciplines

including the first observation of

bacteria and protists with a microscope

by anton van leeuwenhoek

the groundbreaking were carried out by

william harvey

on a detailed analysis of the heart and

blood circulation

the pioneering experiments on the

physical properties of gases by the

founder of modern chemistry

robert boyle and charles darwin a

naturalist who publicly announced his

revolutionary theory of evolution

through his expeditions around the world

one of

darwin's breakthrough observations

explaining the similarities of organisms

is brought by the principle that species

evolved from common ancestors

he also posited the process of natural

selection

in which stronger species may adapt

successfully against the changing

requirement of the environment

his famous book on the origin of species

created a worldwide uproar an intense

debate everywhere

stating the concept of man evolving from

the common ancestors

along with apes and monkeys was

unacceptable due to the deep religious

belief that man was created by god

eventually further scientific

investigations and evidences from dna

technology

decades later proved that darwin's

theory of evolution was based in fact

and that's it the enlightenment by

science and through science

that has shaped our society today thank

you and i'll see you in a while

welcome back and here's the second part

of this chapter

the waves of technology again please

enjoy this video

the term wave of technology is described

as the succession

in change of human civilization across

history

these waves which are referred as the

era of change is also characterized by

the use of tools and machines that help

mankind flourish the earth

eventually these mere tools became

technology which is now a driving force

for social change

these waves of change were built on the

foundation of knowledge revolution

since knowledge itself became a powerful

tool in molding the course of

civilizations

the first wave is agricultural

revolution most historians have labeled

an agricultural revolution as the

transition period between hunters and

gatherers

into stationary farmers human

settlements have now learned how to

domesticate both plants such as corn

and practice crop rotation as an

efficient way of utilizing farmlands

as well as tame wild animals such as

wild cattle and wild boars

because of successful domestication food

was readily available to everyone which

has led to population growth

and demand of larger settlements leading

to problems of waste disposal

and proper sanitation consequently land

has now become the basis

of several criteria of both personal and

social

implications such as the status of an

economy

lifestyle conditions and even the

fundamentals of politics

land ownership has also become the key

figure of social stratification wherein

the elites are generally the feudal

lords

while the workers are labeled as

peasants and slaves often regarded as

the landless people and the poor

the beginning of the 19th century marks

the start of the second revolution

popularly known as the industrial

revolution

as food supplies increased and living

conditions improved the population in

europe boosted the demand for goods

such as textiles and many farmers became

factory workers

[Music]

cotton was primarily cultivated for

textiles

during this times cotton was labor

intensive making slavery

and child labor became widespread in

europe and u.s

tools such as the spinning jenny was

also invented and was one of the key

developments in the industrialization

of weaving during the industrial

revolution the introduction of steam

engines as the new source of power

was also one of the most important

factors in the development of our driven

machines

and as the demand for gold increased

miners dug deeper into coal deposits

the industrial revolution was the time

when many important inventions made work

easier and cheaper

establishment of factories as model of

efficiency for mass production

has also became common consequently the

industrial revolution

made negative impacts in the environment

as it concentrates population growth and

generate pollution

as well as encourage imperialism due to

domination of foreign lands and

political interests over various

resources

the third wave of technology is the most

recent information revolution

or also known as the computer age by the

end of the 20th century

computer technology has changed the

world the information revolution is

making a difference to millions of

people

while the nation's economic success is

already based on the control of ideas

this wave of technology is driven by two

factors

first the rise of dynamic new industries

based on scientific breakthroughs

and second to enhance manipulative

abilities via computers

personal computers had become widespread

in its ability to connect over local and

national networks

such as lisa which is the first apple

computer before macintosh

eventually the internet was also

developed by the us department of

defense for security purposes

as well as utilized by scientists to

communicate each

other also the development of fiber

optic cables

and companies like intel develop faster

microprocessors for a more rapid rate of

incoming signals in computers

in the late 1900s world wide web was

also developed for commercialization

new forms of communication were

introduced such as electronic mail or

popularly called as email for a faster

and more convenient tool for

communication

and prosumer platforms and social media

became rampant in the virtual world

now to sum it up technology has really

molded society

across history and became an essential

driving force for social change

so that's it i hope you have learned

something and enjoy the videos

at the same time again this is ian

saying that

scientific knowledge is a scientific

power and with great power

comes great responsibility in our

society

see ya
