Ibn Al-Haytham, born in Basra, Iraq, is often called the father of optics. His groundbreaking work laid the foundation for the scientific method and transformed our understanding of light and vision. Beyond optics, he made important contributions to astronomy and influenced architectural design principles. Recently, Brother Mohamed Durgana highlighted Ibn Al Haytham’s legacy and assigned families a hands-on project: building a camera obscura. This simple device demonstrates the principles that Ibn Al Haytham studied and connects us to the scientific achievements of the Golden Age of Islam.
This post explores Ibn Al Haytham’s impact on science and architecture, explains the camera obscura project, and offers practical tips for families to engage with this fascinating history.
Ibn Al Haytham’s Contributions to Science
Ibn Al Haytham lived during the 10th and 11th centuries, a period often called the Golden Age of Islam. His most famous work, Kitab al-Manazir (Book of Optics), revolutionized the study of light and vision. Before him, many believed vision occurred because the eyes emitted rays. Ibn Al-Haytham proved that vision happens when light reflects off objects and enters the eyes.
The Birth of the Scientific Method
One of Ibn Al Haytham’s greatest legacies is his approach to scientific inquiry. He emphasized observation, experimentation, and verification. This method laid the groundwork for modern science. Instead of relying on assumptions or philosophical arguments, Ibn Al-Haytham tested hypotheses through experiments.
For example, he used lenses and mirrors to study how light behaves, carefully recording results and adjusting his theories. This approach influenced later scientists such as Galileo and Newton.
Advances in Astronomy
Ibn Al-Haytham also studied celestial bodies. He questioned the Ptolemaic model of the universe and suggested that the apparent movement of stars could be explained by the Earth’s rotation. Although his ideas were not fully developed at the time, they contributed to the gradual shift toward modern astronomy.
The Camera Obscura and Its Connection to Ibn Al-Haytham
The camera obscura is a simple optical device that projects an image of its surroundings onto a surface inside a darkened room or box. It works by allowing light through a small hole, which then casts an inverted image on the opposite wall or screen.
How Ibn Al Haytham Inspired the Camera Obscura
Ibn Al Haytham was the first to describe the principles behind the camera obscura. He explained how light travels in straight lines and how a small aperture can project an image. His observations helped artists and scientists understand perspective and vision.
The camera obscura became a tool for painters to capture realistic scenes and later influenced the development of photography and modern cameras.

Building Your Own Camera Obscura: A Step-by-Step Guide
Brother Mohamed’s assignment invites families to create a camera obscura at home. This hands-on project helps deepen understanding of Ibn Al Haytham’s discoveries and makes science accessible and fun.
Materials Needed
A room or box that can be darkened completely
A piece of cardboard or thick paper
Aluminum foil or a thin metal sheet
A pin or needle to create a small hole
White paper or cloth for the projection screen
Tape or adhesive
Steps to Create the Camera Obscura
Choose a Room or Box
Select a small room or a large box that can be darkened. The darker the space, the clearer the image will be.
Darken the Space
Cover windows and doors with blackout curtains or thick blankets. Eliminate all light sources inside the room.
Create the Projection Hole
Cut a small square from the cardboard and cover it with aluminum foil. Use the pin to poke a tiny hole in the center. This will act as the aperture.
Position the Screen
Tape the white paper or cloth on the wall opposite the hole. This surface will display the projected image.
Install the Aperture
Place the cardboard with the pinhole over a window or opening, ensuring no other light enters.
Fine-Tune and Observe
Adjust the distance between the hole and the screen to sharpen the image. Look for an inverted projection of the outside scene on the screen.
What to Look For
The image will appear upside down and reversed left-to-right.
The smaller the hole, the sharper but dimmer the image.
Larger holes create brighter but blurrier images.
This experiment shows how light travels and how our eyes receive images, just as Ibn Al-Haytham described.
The Influence of Ibn Al Haytham on Architecture
Ibn Al-Haytham’s work on light and vision also influenced architectural design. Understanding how light enters and moves through spaces helped architects create buildings that use natural light effectively.
Designing with Light in Mind
Windows and Openings: Architects learned to position windows to maximize daylight while minimizing glare.
Light Wells and Courtyards: These features bring light into interior spaces, improving comfort and visibility.
Shading and Reflection: Using materials and shapes that reflect or diffuse light helps control brightness and temperature.
These principles are still relevant today in sustainable architecture and building design.
Preparing for the Quiz and Sharing Your Findings
Next week’s quiz on Ibn Al Haytham will test knowledge of his life, discoveries, and impact. To prepare:
Review his contributions to optics and astronomy.
Understand how the camera obscura works and why it matters.
Reflect on how his scientific method changed the way we study nature.
When sharing your camera obscura project, consider these points:
Describe the setup and materials you used.
Explain what you observed and how the image changed with adjustments.
Connect your experience to Ibn Al Haytham’s discoveries.
