Beer, Ale, Wine
Who drank the first beer? Getting buzzed definitely has very deep historical roots. The earliest evidence of any fermented beverage is fruit-based, aka wine, and comes from the Jiahu site in China and dates back to around 7,000 BCE (9,000 years ago). In addition to fermented beverage residue in China, we have grain-based, aka beer/ale,
Bread Making Pushed Back
The groundbreaking discovery that humans were making bread 14,000 years ago, before the advent of agriculture, was published in 2018. Since grain is easy to grow, does this suggest agriculture might have started a few thousand years earlier? Under study, but the discovery of bread-making from around 14,000 years ago indeed suggests that humans were experimenting

The Invention of Bread
Since grain is easy to grow, does this suggest agriculture might have started a few thousand years earlier? Under study, but the discovery of bread-making from around 14,000 years ago indeed suggests that humans were experimenting with grains before the widespread adoption of agriculture, which is traditionally dated to about 12,000 years ago with the

The Domestication of Rice
In the lush, fertile lands of the Yangtze River Valley in ancient China, early inhabitants achieved a milestone that would revolutionize human society: the domestication of rice. Around 8,000 BCE, these innovative communities began to cultivate wild rice, laying the groundwork for sedentary agriculture and complex civilizations. This agricultural breakthrough not only provided a stable

Discovery: Neanderthal Symbolic Thought
It’s clear: neanderthals created art. The discovery of cave paintings in Spain, dated to over 64,000 years ago, marked a profound shift in our understanding of Neanderthals. This corrected the longstanding perception that Neanderthals lacked symbolic thought and artistic expression. To learn more, check out Beyond Human Bias: Reassessing Neanderthal Intelligence.

The Invention of Calculus
Invented by Newton in the 1660s (pub. 1687) and independently by Leibniz in the 1680s (pub. 1684). Both built on Galileo’s popularizing the idea of the infinitesimal. Calculus, the mathematical study of continuous change, introduced the concepts of differentiation and integration, providing tools to model and analyze motion, growth, and the infinitesimal. Newton, working primarily

The Birth of Logic
In the vibrant intellectual climate of Ancient Greece, the 6th century BCE marks the embryonic stage of formal logic, attributed to the philosopher Thales of Miletus (around 624-546 BCE). Thales, recognized as the first of the Seven Sages of Greece, embarked on a quest that laid the foundational stones of logical thought. He shifted the

Rediscovery of the Library of Ebla: circa 2350 BCE
In 1975, Italian archaeologist Paolo Matthiae and his team unearthed the remarkable Library of Ebla at Tell Mardikh, Syria, revealing a trove of around 20,000 clay tablets and fragments. This discovery dramatically expanded our understanding of ancient Near Eastern civilizations, introducing Eblaite as a previously unknown Semitic language and providing unprecedented insights into the culture,

Hourglass
Hourglasses, also known as sandglasses or sand timers, were first used in the 14th century, although it is unclear exactly when they were invented. The earliest written reference to an hourglass dates back to the early 14th century in Europe, but they may have been used earlier in other parts of the world. Hourglasses were
Spherical Earth
The Greeks knew the Earth is spherical. For example, Pythagoras (570-495 BCE), Aristotle (384-322 BCE), and Euclid (circa 450 BCE) wrote about the Earth as a sphere. Eratosthenes (276-194 BCE) even calculated the circumference of the Earth to within 1%. He also wrote about the idea that India could be reached by sailing westward from
Man Made Glass
The earliest known man made glass dates back to circa 3500 BCE and to Egypt and Eastern Mesopotamia. Discovery of glassblowing around 1st century BC was a major breakthrough in glass making.
Electron Microscope = Nanoworld Discovered!
Starting in 1931 with the invention of the electron microscope, the nanoworld became visible to us. The nanoworld contains items as small in diameter as 1 micrometer (1 micron) to a diameter 1,000 times smaller, a diameter of 1 nanometer. The nanoworld includes the smallest single celled organisms, the smallest bacteria as well as viruses,

Earliest Known Magnification
The earliest known magnification dates back to the first century. These simple early magnification devices consisted of using natural crystals or a glass globe filled with water. It is reasonable to assume the use of natural crystals for magnification was around for many thousands of years. One possible specimen is the Nimrud lens dating back

Major Religion: Hinduism
Hinduism, one of the world’s oldest religions, emerged around 1100 BCE, several centuries after the Indus Valley Civilization collapsed. Hinduism has no known roots in the IVC, but it’s a topic to follow as we uncover clues. There was a several century gap from the collapse of the IVC to the rise of the early
