The Birth of Algebra and Algorithms
Math without algebra would be like music without notes. The Persian mathematician Al-Khwarizmi, working in Baghdad’s House of Wisdom, wrote books that gave us the words algebra and algorithm. His step-by-step problem-solving approach, found in his famous text, made math easy to share and teach.
Thanks to Al-Khwarizmi:
- We use “algebra” (from his book al-jabr) for solving equations.
- His name inspired the word “algorithm” (a set of steps to solve problems).
- The decimal number system (what we now call Arabic numerals) replaced cumbersome Roman numerals and helped everyone from merchants to scientists.
His work influenced Europe for centuries. For more on his legacy and how numbers travel the world, visit this summary on Al-Khwarizmi.
Optics, Light, and the Scientific Method
If you’ve ever taken a photo, thank Ibn al-Haytham—his work sparked the science behind cameras. Living in Cairo around 1000 CE, he wrote the Book of Optics. He didn’t just guess how light worked; he tested ideas, measured results, and used experiments.
Key advances from Ibn al-Haytham:
- Explained vision and light reflection using experiments, not just theory.
- Described the camera obscura, which led to the invention of cameras.
- Used what we now call the scientific method—observation, hypothesis, experiment, and proof.
His habit of questioning and testing changed science forever. Dive into how he shaped both optics and research in the Book of Optics.

How the Ottomans Rose and Spread Their Power
In the late 1200s, Turkic warriors built a small state on the edge of the crumbling Byzantine Empire. Their leader, Osman, gave his name to the new Ottoman dynasty. Over the next few centuries, the Ottomans expanded thanks to strong sultans, advanced armies, and clever alliances. When they conquered Constantinople (now Istanbul) in 1453, they not only ended the Byzantine Empire, they sparked a new era.
The empire’s reach soon spread across:
- Southeast Europe (including the Balkans, Greece, and Hungary)
- North Africa (from Algeria to Egypt)
- The Middle East (all the way to the Persian Gulf and Red Sea)
At its height, the Ottoman Empire controlled lands on three continents. These regions became linked by trade routes, roads, and strong rule that united cities and markets from Cairo to Budapest.
Carrying Forward a Proud Heritage
The Ottomans saw themselves as inheritors of the Umayyad, Abbasid, and other earlier Muslim civilizations. They protected major holy sites and welcomed doctors, poets, and builders from across the Muslim world. They built schools and supported scholars in fields like astronomy and medicine.
This legacy was more than words. Ottoman Istanbul, with its grand mosques, became a symbol of cultural blending. The famous architect Mimar Sinan designed hundreds of buildings with beautiful domes and sweeping arches, carrying forward ideas from Damascus and Cairo but making them Ottoman.
Governing a Diverse Empire
One of the Ottomans’ greatest strengths was their ability to rule many different peoples. Christians, Jews, and Muslims all lived within the empire, each following their own laws and traditions. The Ottomans used the “millet” system to organize communities by faith, giving each group a measure of autonomy.
This approach allowed:
- Freedom of worship across many cities and villages
- Religious courts to settle community disputes
- Teachers and scholars to share knowledge across languages and faiths
This mix created a mosaic of cultures—bazaars bustled with goods from Asia and Europe, while poets and mathematicians exchanged ideas in busy coffeehouses.
Ottoman Administration, Law, and Trade
Ottoman rulers understood the power of clear rules and good administration. They split the empire into provinces, each led by a governor (called a “pasha”) who answered to the sultan. Civil servants and scribes, trained from a young age, made sure that taxes were fair and justice was served.
The Ottomans gave the world a legal code called the “Kanun,” which complemented Islamic law (sharia). This allowed courts to solve everyday disagreements about business, land, and families. Their postal networks, roads, and ports kept goods and ideas flowing smoothly.
Ottoman traders moved silk, coffee, and spices along ancient routes. Istanbul became a crossroads where European merchants and Asian traders met—sometimes competing, sometimes cooperating, but always exchanging new products and inventions.

Decline and the Shift of Global Power
By the late 1600s, the Ottomans faced growing problems. Europe’s new trade routes, rising armies, and changing technology put pressure on the old empire. After centuries of rule, corruption and costly wars strained the treasury. European rivals blocked trade and pushed borders back.
As the Ottomans weakened, countries like Britain, France, and Russia claimed more shares of global trade and power. Old centers like Istanbul slowly gave way to new financial and political hubs in London and Paris. When the empire finally ended after World War I, it marked a clear shift—world power now centered in Europe.
If you want to know more about why the Ottoman decline changed history’s course, the BBC’s Ottoman Empire overview offers a useful timeline and perspective.
The Ottoman Empire, with its years of steady rule, creative government, and rich culture, shaped the modern world in ways that live on today—in law, art, cuisine, and daily life from the Balkans to the Middle East.
Art, Culture, and Everyday Influence
The Muslim world didn’t just build empires and make inventions; it shaped culture and everyday life in ways that still resonate today. Art, literature, music, and architecture were interwoven with daily customs, expressing faith, identity, and creativity. These cultural contributions created a shared language of beauty and function that crossed borders and influenced many societies around the world.
Timeless Art: Geometry, Calligraphy, and Symbolism
One of the most striking features of Muslim art is its use of intricate geometric patterns. These designs weren’t just decoration; they reflected a deep respect for order, balance, and infinity. Think of a mosaic tile that seems to stretch endlessly in every direction. This repetition and symmetry symbolize the infinite nature of creation.
Calligraphy—the art of beautiful writing—held special significance. Because depicting living creatures was often avoided, words became the primary artistic expression. Arabic script flowed across walls, pottery, and textiles, turning holy texts into moving visual poetry. The elegance of calligraphy combined with geometric patterns created mesmerizing works that invite contemplation.
Vegetal motifs, with stylized leaves and vines, added life and softness to the often rigid geometry. Together, these elements show how Islamic artists turned mathematics into art, bringing harmony between the spiritual and physical.
