Emerging areas in physics

Physics, at its core, is the study of the natural world. It is about understanding the fundamental rules that govern everything around us – from the smallest particles to the largest galaxies. As science progresses, new fields of physics emerge, exploring unknown territories and offering innovative approaches. Let’s take a deeper look at some of these emerging fields, keeping our explanations simple and straightforward.

Quantum physics and quantum mechanics

Quantum physics studies the behavior of matter and energy at the microscopic level. It is primarily concerned with the smallest particles, such as atoms and subatomic particles, and the way they interact. Quantum mechanics is a part of quantum physics that focuses on the mathematical framework describing these interactions.

Visual example

Imagine you are watching a movie frame by frame. Every frame is like an observation in quantum mechanics, and the whole movie is based on the behavior of particles over time. Let's imagine:

The strange nature of quantum mechanics is summarized by famous experiments such as the double-slit experiment. In this experiment, particles pass through two slits and create an interference pattern, demonstrating the wave-particle duality of nature.

Interference Pattern: This is the pattern formed when waves overlap and combine. In the case of the double-slit experiment, even singular particles can form this pattern.

String theory

String theory attempts to unify all the fundamental forces of nature, suggesting that particles are not zero-dimensional points, but one-dimensional strings. These "strings" can vibrate at different frequencies.

Visual example

String theory proposes a multi-dimensional universe, suggesting the existence of up to 11 dimensions, as opposed to our usual perception of three spatial dimensions and one time dimension.

Dark matter and dark energy

Dark matter and dark energy are two of the deepest mysteries in physics. While dark matter holds galaxies together, dark energy is believed to be the cause of the accelerated expansion of the universe.

Visual example

Consider this simple visual representation:

Despite its name, dark matter is not "dark" but invisible and interacts with normal matter through gravity.
On the other hand, dark energy makes up about 68% of the universe, while dark matter accounts for about 27%. The rest, less than 5%, is everything else, including planets, stars, and galaxies.

Nano

Nanotechnology involves manipulating matter on the atomic or molecular scale, particularly sizes ranging from 1 to 100 nanometers. This emerging field of physics paves the way for creating new materials and devices with unprecedented properties.

Visual example

Think about rearranging the building blocks on a smaller scale:

Nanotechnology is used in many fields such as medicine, electronics and energy. It is about manipulating atoms and molecules to create new structures that can perform incredible functions, such as targeted drug delivery systems in the medical field.

Astrophysics

Astrophysics studies the behavior, physical properties and processes of celestial objects and phenomena. It combines theories from different fields such as classical mechanics, electromagnetism and quantum mechanics.

Visual example

Imagine looking at a star and the planets orbiting around it:

Astrophysicists attempt to understand phenomena such as black holes, neutron stars, and the overall life cycle of stars.

Biophysics

Biophysics uses the principles of physics to study biological systems. It creates models and experiments to understand the function and structure of biological molecules, cells, and ecosystems.

Visual example

Picture of DNA being analyzed from a structural perspective:

Applications of biophysics include understanding how enzymes work, designing nanoparticles for drug delivery, and creating artificial organs or tissues through tissue engineering.

Conclusion

From the very tiny building blocks of the universe to the unfathomable vastness of galaxies, emerging fields of physics open the door to a deeper understanding of everything around us. By exploring these innovative fields, physicists attempt to answer some of the most fundamental questions and solve some of the biggest mysteries. Whether through the strange behavior of tiny particles in quantum physics or the vast scale of the universe in astrophysics, these emerging fields constantly expand our horizons and enrich our knowledge.
