How did the philosophical method of ancient Greek philosophers, like Thales of Miletus and Aristotle, differ from the modern scientific method?
- Ancient Greek philosophers heavily relied on empirical evidence obtained through experimentation, while the modern scientific method is based on theoretical speculation.
- Ancient Greek philosophers focused on systematic testing and evaluation of results, whereas the modern scientific method emphasizes thought and argument.
- Ancient Greek philosophers lacked the component of experimental evidence in their method, whereas the modern scientific method proposes a hypothesis, systematically tests it, and evaluates it on the strength of the results. (correct)
- Ancient Greek philosophers did not propose any hypotheses, while the modern scientific method begins with a hypothesis.

What was significant about Alhazen's studies of dissected bulls' eyes?
- They disproved the need for empirical evidence in scientific discovery.
- They validated existing theories of optics from ancient Greece.
- They were the first recorded instance of scientific experiments. (correct)
- They demonstrated the importance of mathematics in scientific research.
Why is the ability to revise previously held truths considered a mark of a true scientist?
Why is the ability to revise previously held truths considered a mark of a true scientist?
- It allows scientists to disregard empirical evidence in favor of theoretical arguments.
- It maintains the status quo of established scientific theories.
- It reflects an understanding that scientific knowledge is always subject to change and improvement. (correct)
- It ensures personal recognition and fame within the scientific community.

Study Notes
- Science is humanity's attempt to understand how the universe works, using research, insight, and discoveries in the search for truth.
- Humanity has always been driven to understand the world.
- Philosophers in ancient Greece were the first to explain what they observed.
- Early philosophical methods lacked experimental evidence, leading to inaccurate ideas.
- Thales of Miletus (6th century BCE) proposed that water is the primary substance of the cosmos because it is essential for life and found everywhere.
- Aristotle wrote on scientific subjects, from physics and biology to astronomy, laying the foundations for future work.
- Aristotle made errors due to relying on thought and argument rather than empirical proof, such as that heavier objects fall faster than lighter ones.
- Early thinkers made vital findings despite the lack of a reliable scientific method.
- Halley's comet was observed in China in 240 BCE.
- Zhang Heng explained eclipses and created a star catalog about 300 years later.
Scientific Dawn
- European progress in science stalled during the Middle Ages.
- Knowledge shifted to the Islamic world, inspiring advances in scientific thinking.
- Important writings from Greece and India were moved to The House of Wisdom in Baghdad as of the 8th century CE.
- Scholars nurtured at the House of Wisdom included al-Khwarizmi, a mathematician who wrote on trigonometry, algebra, and astronomy.
- Alhazen, an innovator in optics, conducted early scientific experiments through studies of dissected bulls' eyes.
Progression of Ideas
- A true scientist can evaluate and revise previously held truths.
- Science is never finished. Scientific work can be superseded.
- In 1590, Galileo Galilei disproved Aristotle's theory of falling bodies
- Instead, Galileo asserted that objects fall at the same finite speed regardless of mass.
- Galileo's support for Copernicus's heliocentric universe led to him being declared a heretic.
- Galileo paved the way for understanding of the Universe.
Science Comes of Age
- Hypothesis is proposed
- Systematically tested
- Evaluated on the strength of the results
- Early thinkers made vital findings
