Arpan Gupta Data Scientist, IITian's video: Where do we exist We exist everywhere or nowhere Maths Behind Quantum Physics Spiritual Touch

Do you know where do we exist in this universe .If I ask you you would tell your location name .But actual scientific experiments shows that a particle can exist anywhere with certain probabilities.Only when someone else try to detect the particle it stops its wandering and become visible at some location . Likewise Monks like Buddha ,Kabir etc have found this truth long before and they say we exist everywhere .Just an intensity is needed inside you. Monks could time travel like a warmhole in physics .Even Einstein could realized these things around 200 years ago. In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle free to move in a small space surrounded by impenetrable barriers. The model is mainly used as a hypothetical example to illustrate the differences between classical and quantum systems. In classical systems, for example, a particle trapped inside a large box can move at any speed within the box and it is no more likely to be found at one position than another. However, when the well becomes very narrow (on the scale of a few nanometers), quantum effects become important. The particle may only occupy certain positive energy levels. Likewise, it can never have zero energy, meaning that the particle can never "sit still". Additionally, it is more likely to be found at certain positions than at others, depending on its energy level. The particle may never be detected at certain positions, known as spatial nodes. The particle in a box model is one of the very few problems in quantum mechanics which can be solved analytically, without approximations. Due to its simplicity, the model allows insight into quantum effects without the need for complicated mathematics. It serves as a simple illustration of how energy quantizations (energy levels), which are found in more complicated quantum systems such as atoms and molecules, come about. It is one of the first quantum mechanics problems taught in undergraduate physics courses, and it is commonly used as an approximation for more complicated quantum systems.
