I'm asking for some useful links about non-commutitative geometry: some basics, related materials, anything. Something to start the subject with. Any explanations welcome as well.

Non-commutative geometry is a branch of mathematics that studies spaces and structures that do not follow the usual rules of multiplication. In traditional geometry, the order of multiplication of two elements does not matter, but in non-commutative geometry, this is not the case. Non-commutative geometry has applications in both mathematics and theoretical physics.
Non-commutative geometry is different from traditional geometry in that it allows for the multiplication of elements to not be commutative, meaning the order of multiplication matters. This allows for the study of non-commutative spaces, which are not able to be described by traditional geometry. Non-commutative geometry also uses tools from abstract algebra and functional analysis, making it a more abstract and complex field of study.
Non-commutative geometry has applications in many fields, including theoretical physics, coding theory, and cryptography. It has been used to study non-commutative spaces in quantum mechanics and string theory, as well as in the development of error-correcting codes for data transmission. Non-commutative geometry has also been applied to cryptography, specifically in the development of quantum-resistant cryptographic algorithms.
Some notable figures in the field of non-commutative geometry include Alain Connes, who developed the concept of non-commutative geometry in the 1980s, as well as mathematicians Maxim Kontsevich and Nigel Higson. Non-commutative geometry has also been influenced by the work of physicists such as Edward Witten and Stephen Hawking.
Current research topics in non-commutative geometry include the development of new methods for studying non-commutative spaces, such as the use of spectral triples and noncommutative integration. There is also ongoing research into the applications of non-commutative geometry in areas such as quantum gravity and topological insulators. Additionally, there is a growing interest in the connections between non-commutative geometry and other areas of mathematics, such as number theory and algebraic geometry.
