Albert Einstein
Albert Einstein, born in 1879 in Ulm, Germany, is often the first name that comes to mind when we think of “genius.” His general theory of relativity, published in 1915, redefined how we understand gravity—not as a force, but as the warping of spacetime. This radical concept forever changed how we view the universe.
In addition, Einstein’s explanation of the photoelectric effect, where light can eject electrons from a material, earned him the 1921 Nobel Prize in Physics. His famous equation, E=mc², revealed that mass and energy are interchangeable—laying the foundation for nuclear energy and, later, nuclear weapons.
Despite his towering intellect, Einstein was a pacifist and humanitarian, advocating for civil rights and global peace throughout his life.
Interesting fact: As a child, Einstein was thought to be slow because he didn’t speak until he was four. Today, that speech delay is known as the “Einstein Syndrome.”

Stephen Hawking
Born in Oxford in 1942, Stephen Hawking rose to prominence despite being diagnosed with ALS at just 21. Doctors gave him two years to live, but he defied the odds and lived for over five decades—continuing to work, write, and speak through a computerized voice.
Hawking’s most influential discovery was that black holes emit radiation—now called Hawking radiation. This challenged the belief that nothing could escape a black hole. His bestselling book, A Brief History of Time, helped millions of people grasp complex cosmological theories.
In addition to science, Hawking was a cultural icon. He made appearances in The Simpsons, Star Trek, and The Big Bang Theory—always with a sense of humor.
Interesting fact: Despite being almost entirely paralyzed, Hawking experienced zero gravity on a special NASA flight, floating weightlessly like an astronaut.

Marie Curie
Marie Curie, born in 1867 in Warsaw, broke barriers as both a woman and a scientist. After moving to Paris to study at the Sorbonne, she teamed up with her husband Pierre Curie to discover two new elements: polonium and radium.
Her groundbreaking research led to the development of the concept of radioactivity, which has since completely revolutionized medicine, especially in cancer treatment. She became the first woman to win a Nobel Prize—and the only person to win in two different sciences: Physics and Chemistry.
Curie often carried radioactive materials in her pockets, unaware of the long-term dangers.
Interesting fact: Her notebooks from the 1890s are still so radioactive that they’re stored in lead-lined boxes and require protective gear to handle.
Note: If you’d like to know more about fascinating Marie, we’d recommend following book, written by her daughter Eve Curie: “Madame Curie: A Biography”.
Leonardo da Vinci
Leonardo da Vinci, born in 1452 in Vinci, Italy, wasn’t just an artist—he was a true Renaissance man. While most people know him for Mona Lisa and The Last Supper, his notebooks reveal a mind fascinated by anatomy, physics, architecture, and flight.
He sketched designs for helicopters, tanks, and even a robotic knight—centuries ahead of his time. His anatomical drawings are so detailed that modern doctors still reference them.
Da Vinci wasn’t only a thinker; he was deeply curious, observing everything from how birds fly to how water flows. He never stopped asking “why.”
Interesting fact: Leonardo wrote many of his notes in mirror writing, which can only be read using a mirror—possibly to keep his ideas secret or simply because he was left-handed.

Nikola Tesla
Nikola Tesla, born in 1856 in Smiljan (modern-day Croatia), revolutionized how we use electricity. He championed alternating current (AC), which is still the standard for electrical power today. His invention of the Tesla coil and induction motor paved the way for wireless power and modern electronics.
Tesla also envisioned wireless global communication long before the internet existed. He once claimed he could create a “world wireless system” to transmit messages, images, and even power wirelessly.
However, Tesla died nearly penniless, often overshadowed by more commercially successful figures like Thomas Edison.
Interesting fact: Tesla was obsessed with the numbers 3, 6, and 9, believing they held the secrets to the universe.
Isaac Newton
Born in Woolsthorpe, England, in 1643, Isaac Newton is renowned for his formulation of the three laws of motion and the law of universal gravitation. His seminal work “Philosophiæ Naturalis Principia Mathematica,” published in 1687, laid the groundwork for classical mechanics, providing a mathematical framework to describe the motion of objects and the forces acting upon them.
Newton’s methodical approach to scientific inquiry, characterized by mathematical rigor and empirical observation, set a precedent for scientific methodology that endures to this day.
His laws of motion elucidated the fundamental principles governing the physical world, and his law of universal gravitation explained the force that governs the orbits of celestial bodies. Newton’s insights provided a unifying framework for understanding both terrestrial and celestial phenomena.
Interesting fact: Legend says he discovered gravity after watching an apple fall from a tree. While the story is probably dramatized, Newton did say the falling apple sparked his thoughts on attraction between bodies.

Richard Feynman
Richard Feynman, born in New York City in 1918, made profound contributions to the field of quantum mechanics, particularly in the realm of quantum electrodynamics (QED).
His development of the Feynman diagrams, a visual representation of particle interactions, revolutionized the way physicists approach complex calculations in the quantum world. Feynman’s deep insights into the behavior of subatomic particles earned him a Nobel Prize in Physics in 1965.
Beyond his scientific prowess, Feynman’s unique teaching style and capacity to demystify intricate concepts through relatable anecdotes endeared him to peers and students alike. His lectures, collected in volumes like “The Feynman Lectures on Physics,” continue to inspire a new generation of physicists and scientists.
Interesting fact: Feynman once picked up Portuguese just to give a lecture in Brazil—because he thought it would be fun.

Ada Lovelace
Born in London, England, in 1815, Ada Lovelace, often referred to as the world’s first computer programmer, left a huge mark on the realm of computing long before computers as we know them existed. Lovelace’s analytical brilliance emerged at a young age, fostered by her upbringing in a family that valued intellectual pursuits.
Lovelace’s collaboration with Charles Babbage on his visionary Analytical Engine yielded comprehensive notes that went beyond mere translation.
Her notes included an algorithm intended for the engine, which is now recognized as the world’s inaugural computer program. Her insights into the engine’s capabilities foresaw the potential for computers to perform operations beyond numerical calculations, effectively pioneering the concept of software.
Interesting fact: The programming language Ada is named in her honor.

John von Neumann
John von Neumann, born in Budapest in 1903, was a child prodigy who could divide eight-digit numbers in his head by the age of six. He later became a powerhouse in fields ranging from game theory to quantum mechanics to computer science.
He designed the von Neumann architecture, a computer framework that separates data and instructions—still used in most computers today. He also played a role in the development of the atomic bomb and laid the groundwork for artificial intelligence.
Von Neumann was known for his razor-sharp wit and photographic memory.
Interesting fact: At Princeton, his colleagues joked that he was the only human who functioned like a computer

Max Planck
Max Planck, born in 1858 in Kiel, Germany, revolutionized physics by introducing the concept of quantum energy. He proposed that energy is emitted in discrete amounts—called quanta—not in a continuous stream. This discovery challenged classical physics and gave birth to quantum theory.
Planck’s constant (h), introduced in 1900, is still a foundational element in quantum mechanics. He won the Nobel Prize in Physics in 1918 for this revolutionary idea.
Even during personal tragedies—including the loss of his son during WWII—Planck remained a steadfast advocate for science and truth.
Interesting fact: Planck was friends with Einstein and was one of the first to support Einstein’s theories when others were skeptical.
