00:00Einstein's universe, the genius who rewrote the cosmos in 1905, a young Albert Einstein

00:05shook the foundations of science with a series of papers we now know as his Annus Mirabilis,

00:10or Miracle Year. Among them, his work on the photoelectric effect proposed a revolutionary

00:15idea, light doesn't just behave as a wave, but also as a stream of discrete particles he called

00:20photons. With this concept, Einstein not only solved a puzzle in physics, but also opened the

00:26door to quantum physics. This discovery, though it may seem abstract, gave rise to technologies we

00:32use daily, from solar panels to light sensors in our cameras. For this work, and not for relativity

00:38as many believe, Einstein received the Nobel Prize in Physics in 1921. But that was just the beginning.

00:46That same year, his theory of special relativity shattered the notion of absolute space and time.

00:51His postulates were simple, but their consequences were astonishing. He showed that time and space

00:58are malleable, deforming based on the observer's speed. Concepts like time dilation and length

01:04contraction went from being science fiction ideas to scientific principles. A practical example of this

01:10is the twin paradox, which tells us that a twin who travels at near light speed would age more slowly

01:15than the one who stays on Earth. But this isn't just a theory, it's a key principle for how GPS works,

01:21ensuring our digital maps are accurate. From special relativity came the most famous equation in

01:27history, E equals mc squared. With it, Einstein revealed that mass and energy are not separate

01:33entities, but two sides of the same coin. This simple formula showed that a small amount of mass can

01:39release a colossal amount of energy. It's the engine behind the sun's energy, which has burned for

01:45billions of years. And on a human level, it is the basis for nuclear energy, both for reactors that

01:51power cities and for weapons that threaten the existence of civilization. Ten years later, in 1915,

01:58Einstein elevated his vision to a cosmic scale with the theory of general relativity, where gravity was

02:03not a force but a curvature of space-time. Imagine the universe as a huge trampoline. A massive planet

02:10like Earth deforms the fabric of space-time, and other objects simply follow the curves of that

02:15deformation. This idea was dramatically proven during a solar eclipse in 1919, when it was confirmed that

02:22starlight bent as it passed near the sun, just as Einstein had predicted. This event catapulted him

02:28to worldwide fame. Einstein's theories, which were purely conceptual in 1905, have become the backbone of

02:35modern technology. Special relativity is crucial for the operation of GPS and communication systems.

02:42The photoelectric effect is the basis for solar panels and photocopiers.

02:48And E equals MC squared not only explained the energy of stars, but also became the basis for

02:53nuclear power and nuclear medicine. However, Einstein's legacy also presents us with an ethical dilemma.

03:01The same formula that explains the energy of the cosmos was also the theoretical key behind the atomic bomb.

03:06This duality marked the second half of Einstein's life, as he became a fervent activist for nuclear

03:12disarmament. His figure transcended that of an isolated genius to become a global moral conscience,

03:18reminding us that scientific knowledge is a tool, and its use, whether to create or destroy,

03:23depends entirely on humanity. The genius who taught us to see the universe in a radically new way left us

03:29with a warning, with great power comes great responsibility. Money explainers.
