Image: Max Planck (1858-1947), Albert Einstein (1879-1955) and Niels Bohr (1885-1962) are scientists who played a key role in the development of quantum physics.
Max Planck is famous for discovering that the energy in electromagnetic radiation (like light) is emitted in discrete quantities called "quanta". This discovery led to the creation of quantum theory and paved the way for quantum physics.
Albert Einstein also made a significant contribution to quantum physics by developing the special theory of relativity, which introduced new ideas about the nature of space and time. He is also famous for his work on the photoelectric effect, which showed that light behaves like both a particle and a wave.
Niels Bohr created Bohr's atomic model, which explained how electrons orbit around the nucleus of an atom. This model was based on the work of Planck and Einstein, and used the ideas of energy quantization and wave-particle duality to explain the behavior of electrons.
Together, these scientists laid the foundations of quantum physics and opened up new avenues of research in physics, chemistry, technology, and other fields even today.
Quantum physics is a branch of science that studies the behavior of very small particles, such as atoms and electrons. This science is very complex, but we can explain it in a simple way for 10 year olds.
Everything is made of particles!
Everything around us, including ourselves, is made of very small particles. These particles are so small that it is impossible to see them, even under a microscope.
Very small particles behave differently from what we experience in our daily lives. For example, a particle can be in two different places at the same time. It sounds crazy, but it's true!
Particles are unpredictable, which means we can't always know exactly where they are or how they will behave. It's as if they were making their own choice.
Observation can change the behavior of particles!
When we observe the particles, it can change their behavior. For example, if we observe a particle moving from one place to another, it might suddenly change direction just because we watched it.
Quantum physics can help us understand certain things in the world around us. For example, computer, cell phone, and internet technology work through quantum physics.
