Many insights of Albert Einstein are now part of popular imagination: black holes, time warps, and wormholes show up in movies and books.
Less famous, but probably the most revolutionary pa...
The most fundamental aspects of nature stay the same.
For example, Einstein's papers on relativity show that the relationship between energy and mass is invariant, ...
We often think of things as the heart of reality. But most often the relationship is more important, not the stuff.
We may think "stuff" like space and time are unchangeable aspec...
The relationship that mattered most to Einstein's ideas was symmetry. Scientists describe symmetry as changes that don't really change anything. More complicated symmetries...
Albert Einstein did not think about symmetry when he wrote his first relativity papers in 1905. He was considering several seemingly unrelated puzzles and connecting the dots.
Unified space-time starts to make sense if we think that the speed of light is a relationship between the distance traveled over time.
Because the speed of light can't change, your lase...
Einstein's special theory of relativity applies only to steady, unchanging motion through space-time, not accelerating motion like an object falling toward Earth.
After Einstein, the pull of symmetry became more powerful.
From the 1950s, invariances took on a life of their own. New symmetries, known as "gauge" invariances, became productive by requiring the existence of everything from W and Z bosons t...
Symmetry, as it is understood, seems not to answer the biggest questions in physics. In some cases, symmetries show the underlying laws of nature that do not show up in reality.
Duality is a closely related idea to symmetry. Wave-particle duality has been around since the beginning of quantum mechanics. But newfound dualities have shown interesting relationships. ...
The idea of symmetry proved very powerful. Giving it up would mean giving up on naturalness - the idea that the universe has to be exactly the way it is for a reason.
But inside black...

According to physicist Albert Einstein, time is not a constant phenomenon as it appears, but is an illusion, and can vary from different vantage points.
Space is three-dimensional, and Time, according to the famous physicist, is the fourth dimension. It also speeds up or slows down, so is actually subjective, as stated in his Theory Of Special Relativity.
Einstein's theory of general relativity says that Time can be bent, stretched and squeezed, and the four-dimensional fabric with a huge mass creates a dimple, or bending of Space-Time, causing gravity.
This effect of time dilation is proven using GPS satellite technology in space, making astronauts not only travel space but in a slightly different time than the earthlings.

A Paradigm theory is a general theory that provides a broad theoretical framework or "conceptual scheme." It offers underlying assumptions, key concepts, and methodology to scientists wor...
A paradigm shift occurs when one paradigm theory is replaced by another:
The term "paradigm shift" was coined by the American philosopher Thomas Kuhn (1922-1996). He argued that science couldn't advance until most people working within a field agree upon a paradigm. Before the agreement, collaboration and teamwork are restricted.
Once a paradigm theory is established, those working within it can start doing normal science. But now and then, normal science reveals anomalies that can't be explained within the dominant paradigm. When the inexplicable results start piling up, it eventually leads to a "crisis."

Genius is not about having an extraordinarily high IQ, or even about being smart. It is not about finishing Mensa exercises in record time or mastering fourteen languages at the age of seven.
Leonardo da Vinci believed you begin by learning how to restructure the problem by looking at it from many different angles.
In order to creatively solve a problem, the thinker should not use the usual approach that is based on past experience. Geniuses use several different perspectives to solve an existing problem and thereby also identify new ones.
Galileo revolutionized science by making his idea visible with diagrams, maps, and drawings. Einstein believed that words and numbers as they are spoken did not play a significant role in his thinking process.
Geniuses seem to develop a skill to display information in visual and spatial forms, rather than only mathematical or verbal lines.
