Should I learn special or general relativity first?
Before learning general relativity you need to learn special relativity,classical mechanics,electromagnetism,fluid mechanics,tensors,differential geometry first. this is the way we physics majors learn general relativity.
Why is special relativity wrong?
The special relativity does not explain the correct relationship between the energy and momentum in the spacetime, so then the energy-momentum equation is incorrect. The potential energy of the three-dimensional particles is good evidence of the correctness of the multi-dimensional energy-momentum equation.
What is the difference between general and special?
When used as adjectives, general means including or involving every part or member of a given or implied entity, whole etc, whereas specific means explicit or definite.
What did I learn about special relativity?
Special relativity is an explanation of how speed affects mass, time and space. As an object approaches the speed of light, the object’s mass becomes infinite and so does the energy required to move it. That means it is impossible for any matter to go faster than light travels.
Do you need calculus for special relativity?
For special relativity, only calculus and vectors will do, but things like electromagnetism and Newtonian mechanics will be very useful.
How do you know if something is general or specific?
Specific ideas refer to particular individuals, ideas, or things and tend to express distinct characteristics that define those individuals, ideas, and things. General ideas usually express the main point or main idea of a piece of writing, often a claim that needs to be proven.
What is the general difference?
The constant difference between consecutive terms of an arithmetic sequence is called the common difference. Example: Given the arithmetic sequence 9,7,5,3,… . To find the common difference, subtract any term from the term that follows it.
How did Einstein come up with special relativity?
Chasing a beam of light Writing a half century later in 1946 in his Autobiographical Notes, Einstein recounted a thought experiment conducted while he was a 16 year old student in 1896 that marked his first steps towards special relativity.
What is special about special relativity theory?
Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object. It is the origin of the most famous equation in science, E = mc2, which expresses the fact that mass and energy are the same physical entity and can be changed into each other.
What are the problems with general relativity?
The two-body problem in general relativity is the determination of the motion and gravitational field of two bodies as described by the field equations of general relativity. Solving the Kepler problem is essential to calculate the bending of light by gravity and the motion of a planet orbiting its sun.
What is the formula for special relativity?
E = mc 2. One of the results of the theory of special relativity is Einstein’s famous equation E = mc 2. In this formula E is energy, m is mass, and c is the constant speed of light.
What is an example of general relativity?
A central idea in general relativity is the “principle of equivalence.”. An example is that two people, one in an elevator sitting on the surface of the earth, and the other in an elevator in outer space accelerating at 9.8 m/s 2, will each observe the same behavior of an object they drop from their hand.
What is the mathematics of general relativity?
The mathematics of general relativity refers to various mathematical structures and techniques that are used in studying and formulating Albert Einstein’s theory of general relativity. The main tools used in this geometrical theory of gravitation are tensor fields defined on a Lorentzian manifold representing spacetime.
