3.3 Changes in science

Memorygame......

Before the 17th century, scientific knowledge mostly came from the Greeks, Romans and Arabs. Their texts were quite often wrongly translated or misunderstood. Philosophers in the 17th century decided they wanted to do their own scientific studies to see if the ancient texts were correct. They were inspired by the free thinkers of the Renaissance and the humanists. This changed the way they saw the world significantly and how people would look at mankind and nature. This new increased interest in knowledge is what we call the scientific revolution. Two new ways of approaching science came up: empirical thinking and rationalism.

Scientific Revolution

Rationalism: Research based on reasoning and logic.

Empirical thinking: Research based on observation and experiments.

Results of research led to knowledge about laws of nature (= how the world works).

Scientific Revolution

Galileo

Built a telescope. Found scientific evidence that the Earth revolves around the sun, heliocentrism.

Newton

Combined rationalism and empirical thinking. Discovered that the Earth pulls objects down with the force of gravity.

Scientific Revolution

Many scholars lived in the Republic in the 17th century. Science flourished.

• 1575 University of Leiden founded.
  
• No censorship, scientists were free to publish theories and ideas. New insights spread quickly.
  
• Many foreign scholars moved to the Republic.

Scientific Revolution

Huygens 

Discovered that light consists of waves. Invented the pendulum clock. Designed a telescope and discovered, for example, a moon near the planet Saturn. Famous mathematician.

Van Leeuwenhoek 

Discovered microorganisms, such as sperm cells and bacteria, using a homemade microscope.
