Albert Einstein’s influence deeply permeates many aspects of modern society.
His theories and ideas have significantly impacted not only the advancement of science and technology but also our daily lives and, ultimately, our worldview.
Now, let me talk a bit more about this influence.
1. Influence on Science and Technology
1-1. GPS Technology
The navigation systems on our smartphones, which we use daily, wouldn’t work accurately without Einstein’s theory of relativity.
GPS satellites orbit the Earth at high speeds, and according to special relativity, time moves slower for them compared to clocks on the ground.
Additionally, general relativity tells us that since satellites are in weaker gravitational fields away from the Earth, time runs faster for them.
These effects combined result in the clocks on GPS satellites running about 38 microseconds faster per day.
If this tiny time discrepancy weren’t corrected, the GPS location data would drift by about 10 kilometers each day.
However, by applying Einstein’s theory to correct this discrepancy, we can now obtain precise location information.
1-2. Nuclear Energy
Einstein’s famous equation, E=mc², demonstrates that mass and energy are equivalent, explaining how immense energy can be extracted from the splitting or fusion of atomic nuclei.
In nuclear power plants, energy is extracted by splitting heavy atomic nuclei like uranium.
A tiny bit of mass is lost and converted into a huge amount of thermal energy.
For example, it is said that when just 1 gram of Uranium-235 undergoes fission, it releases energy equivalent to 20,000 tons of TNT.
However, this principle was also applied to nuclear weapons, a development Einstein deeply regretted.
1-3. Space Research
General relativity explains gravity as the warping of spacetime, and this theory predicted the existence of black holes and gravitational waves, forming the foundation of modern astrophysics.
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) succeeded in detecting gravitational waves for the first time.
This discovery captured the phenomenon of two black holes merging about 1.3 billion light years away, distorting spacetime.
It was a groundbreaking event that proved Einstein’s theory after 100 years.
Today, the field of gravitational-wave astronomy is rapidly developing, offering new insights into our understanding of the universe.
2. Influence on Philosophy and Worldview
2-1. Revolutionizing the Concept of Time and Space
Einstein’s theory of relativity overturned the traditional notions of absolute time and space.
According to special relativity, the flow of time changes based on the observer’s motion, and general relativity shows that time passes more slowly in strong gravitational fields.
These theories greatly influenced how we view the world.
The concept of simultaneity became relative, bringing new perspectives to philosophical debates on causality and free will.
2-2. Challenge to Scientific Determinism
Although Einstein famously said, “God does not play dice,” his theory ironically contributed to the development of quantum mechanics, a probabilistic worldview.
The uncertainty principle in quantum mechanics demonstrates that events at the microscopic level cannot be predicted with complete certainty.
This challenged the notion of a fully deterministic world, sparking new discussions about free will and chance.
3. Influence on Society
3-1. Peace Movements and International Cooperation
In his later years, Einstein became deeply aware of the dangers of nuclear weapons and worked for world peace.
In 1955, he signed the “Russell-Einstein Manifesto” with Bertrand Russell, warning of the dangers of nuclear weapons.
This manifesto eventually led to the Pugwash Conferences, laying the foundation for the nuclear disarmament movement.
Einstein’s pacifist stance has deeply influenced modern scientists.
3-2. Influence on Education
Einstein emphasized the importance of creativity and critical thinking in education.
His famous quote, “Imagination is more important than knowledge,” is still frequently cited in educational contexts today.
This idea contributed to the development of education that fosters problem-solving abilities and creative thinking, rather than mere memorization.
Even today, Einstein’s educational philosophy continues to exert a strong influence.
3-3. Anti-Racism Movements
Having faced discrimination as a Jew, Einstein was a lifelong advocate against racism.
He supported the civil rights movement and worked for the rights of African Americans.
In a 1946 lecture at Lincoln University, Einstein referred to racism as “a disease of white people” and called for its eradication.
His stance influenced the civil rights movement and contributed to the realization of social justice.
4. Influence on Modern Culture
Einstein’s image is widely recognized as a symbol of “genius” or “scientist.”
His wild white hair and serious expression often appear in pop culture and have become part of the public image of scientists.
The widespread recognition of formulas like E=mc² has also helped raise interest in science.
His words and anecdotes continue to convey the importance of science.
In this way, Einstein’s influence extends far beyond science and technology, shaping our worldview, ethics, and society as a whole.
His life and achievements teach us the importance of curiosity, the courage to challenge established concepts, and the responsibility to use science for the betterment of humanity.
