From special relativity to condensed matter physics,
Digging into the core of all areas of physics

Part 1: The Fastest: What Would You See If You Traveled at the Speed ​​of Light?
We introduce the principle of relativity and the principle of constancy of the speed of light, which are the basic foundations of special relativity.
Based on these two principles, all the effects of special relativity can be logically derived.
However, special relativity is a logical deduction for ideal situations and does not apply to most realities.
We will learn about the famous ladder paradox, the rigid body paradox about the properties of materials, the Ehrenfest paradox showing the warping of spacetime, and the twin paradox.
Part 1 also provides a detailed introduction to aerodynamics based on real-world phenomena, exploring the technological hurdles that must be overcome to reach the speed of light.

Part 2: The Largest: The Origin of the Universe
In Part 2, we push the size of space and the length of time to their limits.
The largest size we can think of is, of course, the universe.
First, we will learn about the birth and development of the universe, and its future, based on the Big Bang theory.
And find out what's out there in space.
It organizes various celestial bodies such as stars, planets, satellites, comets, neutron stars, white dwarfs, red dwarfs, black dwarfs, red giants, and supernovae, and explains the mass class that determines the direction of evolution of celestial bodies.
Part 2 also explains the interactions of celestial bodies based on universal gravitation, and introduces the process by which Newton established the law of universal gravitation with the help of two scientists, Kepler and Galileo.

Part 3: The Most Massive: General Relativity
We will learn about Einstein's general theory of relativity to explain the larger dimensions of space and time that cannot be explained by the law of universal gravitation.
We will learn about the genius discovery of general relativity, which holds a 'lofty' position in the entire field of physics, and the birth of modern cosmology.
Based on the general theory of relativity, we can see that gravity is not a 'force' but an effect of accelerated motion caused by the warping of space.
We also explore gravitational waves, GPS, and black holes.

Part 4: The Tiniest: The Bizarre Microscopic World
Part 4 deals with the laws of physics at extremely small scales, that is, the microscopic world.
Even in modern physics, there is no conclusion regarding the smallest building block of matter.
First, we explore the world of atomic physics.
We will learn about how classical theory collapsed in the face of atomic structure and quantum mechanics was born.
Quantum mechanics can be used to interpret the motion of electrons inside an atom, and the Schrödinger equation and the Copenhagen interpretation can be used to understand the motion of electrons.
We also look at the nucleus, which is one-thousandth of a trillionth of an atom in size.
We also learn about the interactions between protons and neutrons that make up the nucleus and nuclear reactions.
Next, we take a look at the even more microscopic world of particle physics.
We introduce quarks, the smallest units that make up protons and neutrons, and learn about the Yang-Mills field theory and the Standard Model theory that explain elementary particles.

Part 5: The Hottest: The Real World of Order in Chaos
Part 5 looks into the world of multiparticle systems and ensembles, that is, the real world rather than the theoretical physical states of individual objects.
To do that, let's first find out what temperature is.
We define the concept of temperature as the average kinetic energy value of a large number of particles, and examine the relationship between various properties of matter and temperature.
The relationship between the physical properties of a system and temperature has developed into a discipline called thermodynamics.
We will examine the theory and laws of thermodynamics and also look at the definition of entropy established through the development of statistical mechanics.
Next, we will learn about the changes in the state of matter as temperature increases, and how to create a high-temperature environment that can cause nuclear reactions.
Part 5 also explains complexity science, discussing the three-body problem, the butterfly effect, and chaotic systems.

Part 6 The Coldest: Order in Low Temperatures
In Part 6, which corresponds to Part 5, we will learn about the phenomena that occur when the temperature is lowered from room temperature to absolute zero.
First, we explore the physical properties of solids based on the fact that substances universally exist in a solid state at relatively low temperatures.
By examining the mechanical, thermal, electrical, and magnetic properties of solids, you can understand the core of materials physics.
And we will summarize the various properties of solids based on quantum mechanics, that is, the contents of solid-state physics.
Finally, we introduce the field of condensed matter physics by learning about quantum mechanical phenomena that occur when the temperature approaches absolute zero: superfluidity, superconductivity, and the quantum Hall effect.


What if you don't have the basic physics skills you need, but don't want to open a textbook?
Extreme Physics is the answer!

It is said that freshmen in science and engineering colleges have difficulty taking classes due to their low basic science skills, and many of them even give up their majors.
Some universities even provide supplementary high school level physics and chemistry classes to freshmen.
It is said that the increase in elective subjects for the convenience of entrance exams resulted in students being reluctant to study difficult subjects.
A decline in basic science skills will inevitably lead to a decline in the overall capabilities of human resources in science and technology.

For science and engineering students reluctant to return to their high school textbooks or to studying for college entrance exams, Extreme Physics can be an alternative.
This is because the book covers all areas of physics while remaining faithful to the fundamental concepts, and the author's unique perspective in guiding the reader through the long journey makes difficult concepts accessible and engaging.
After experiencing all six extreme worlds of physics, 73 scientists, 47 physics principles and theorems, 25 physics experiments and thought experiments, 44 physics theories, and 541 physics and mathematics concepts will all be yours.
