Keywords

💡Scientific Inquiry

Scientific inquiry refers to the process of investigating and discovering truths about the universe through systematic observation, experimentation, and analysis. In the video's theme, it is the driving force behind humanity's journey from ignorance to knowledge, as well as the catalyst for technological advancements and the resolution of societal issues. The script mentions how scientific inquiry has 'decreased the suffering of millions of humans' and led to the creation of gadgets once found only in science fiction.

💡Technological Wonders

Technological wonders are the remarkable innovations and devices that have been developed as a result of scientific discoveries and advancements. The video emphasizes how the world today is filled with such wonders, which were once considered the realm of science fiction. This concept is integral to the video's narrative, illustrating the tangible outcomes of scientific inquiry and their impact on human life.

💡Reproducible Experiment

A reproducible experiment is a scientific procedure that can be independently verified and repeated by other researchers to confirm the validity of the results. The video highlights the importance of this concept through the motto 'NULLIUS IN VERBA' of the Royal Society, which means 'on no one's word.' It underscores the idea that scientific findings should be testable and verifiable by anyone, not just accepted on authority.

💡Natural Philosophy

Natural philosophy is an early form of natural science that encompassed the study of nature and the physical universe, often intertwined with philosophy and sometimes with religious beliefs. The script explains that early scientists, who were not yet called 'scientists,' were natural philosophers. This term is significant in the video's exploration of the history of science, as it represents the precursor to modern scientific disciplines.

💡Scientific Method

The scientific method is a systematic approach to investigating and understanding the natural world, which involves making observations, formulating hypotheses, conducting experiments, and drawing conclusions. The video mentions Francis Bacon's influence on the Royal Society, which adopted practices that would later be associated with the scientific method. This concept is central to the video's theme, as it represents the structured process by which scientific knowledge is acquired.

💡Peer-Reviewed

Peer-reviewed refers to the process by which scientific research is evaluated, validated, and improved upon by other experts in the field before it is published. The script mentions the Society’s Philosophical Transactions as one of the world’s oldest peer-reviewed scientific journals. This concept is crucial to the video's message, as it exemplifies the collaborative and rigorous nature of scientific research.

💡Hypothesis

A hypothesis is a proposed explanation or assumption made on the basis of limited evidence, which can be tested through experimentation and observation. The video uses the example of Darwin's theory of evolution, which was developed through observing variations in different species. The hypothesis is a fundamental concept in the video, as it represents the starting point of scientific investigation.

💡Scientific Revolution

A scientific revolution refers to a significant shift in the understanding or paradigm of a scientific discipline, often triggered by the accumulation of new knowledge or ideas. The video promises to explore moments of revolution within the sciences, indicating that such shifts are pivotal in the history of science. This concept is integral to the video's theme, as it illustrates the transformative power of scientific progress.
