Questions & Answers

Q: Why was there opposition to the use of pictures in mathematics during the 19th and early 20th century?

Some mathematicians and philosophers believed that pictures could be deceptive and undermine formal logic. They argued that relying on pictures as proof was unreliable and should be avoided.

Q: What role did illuminated manuscripts play in the use of pictures in mathematics?

Illuminated manuscripts were often the only versions of mathematical texts that included diagrams, as creating pictures was time-consuming and expensive. Students and less wealthy individuals would often receive copies without diagrams or with blank spaces to fill in.

Q: How did the use of pictures in mathematics change with the advent of printing?

With the invention of the printing press, books could be mass-produced with illustrations. This allowed for the inclusion of diagrams in mathematical texts, making them more accessible to a wider audience.

Q: What is the significance of the invention of graphs and charts in representing information?

Graphs and charts, first introduced in the late 18th and early 19th century, revolutionized the representation of information in mathematics and science. They provided a visual and intuitive way to display and interpret data, making complex information more accessible and understandable.

Summary & Key Takeaways

• Pictures and diagrams have been essential for visually understanding and visualizing mathematical concepts throughout history.

• In the 19th and early 20th century, there was debate and skepticism regarding the use of pictures in mathematics, with some mathematicians and philosophers arguing against their use.

• Advances in technology, such as printing presses and computers, have allowed for the creation of more complex and intricate mathematical pictures, such as fractals and particle physics simulations.
