It also reminds everyone that Functional Analysis is about more than just Hilbert and Banach spaces. An additional resource that would be helpful if you're interested specifically in distributions is Distributions: Theory and Applications , by Duistermaat and Kolk. The book " History of Functional Analysis " by J. Dieudonne connects functional analysis to its roots in differential equations, harmonic analysis and distribution theory.
It connects many of the standard theorems in functional analysis to the applications that inspired them. In prime number theory, density of primes in some interval has prime importance since primes generate the composites most efficiently. Therefore, it is a key metric. And density functional analysis involving primes is a fruitful and fertile research topic in pure mathematics.
Although the following links considers density functional analysis from a physical perspective, I believe they will help you gain valuable insights on some key ideas of functional analysis Good luck! One field where functional analysis is brought close to applications is inverse problems. This is a branch of mathematics concerning indirect measurements.
For a concrete example, consider X-ray tomography. The physical problem is to find the position-dependent attenuation coefficient from measured intensity drop along every line through the object. A machine shoots an X-ray through the object and compares the initial and final intensity. This is repeated for a great number of trajectories. Is the function even uniquely determined by this data? This problem becomes more tractable within a functional analytic framework. The mathematical X-ray tomography question can be reformulated: Is the X-ray transform injective?
If it is injective, it has a left inverse. What happens if one only has some kind of partial data, perhaps with errors? Is there perhaps a good pseudoinverse that is optimal in some way? A weaker version of the adjoint is needed. These endeavors can be taken in a number of different directions. One can study the fine details of stability using microlocal analysis, or extend the theory to geodesics on a manifold which has applications in seismic imaging, for example , or study converge of numerical approximation schemes, or find a way to get a decent X-ray image with minimal radiation dose, or….
I wrote introductory lecture notes on the topic with very little prerequisites: Analysis and X-ray tomography. There are a number of books on different aspects of X-ray tomography. The classics of the mathematical theory are by Helgason and Natterer. There are still open problems in this field, and even more so in the whole field of inverse problems.

A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation; methods for low-rank matrix approximations; hybrid methods based on a combination of iterative procedures and best operator approximation; and methods for information compression and filtering under condition that a filter model should satisfy restrictions associated with causality and different types of memory.

Instead, much of numerical analysis is concerned with obtaining approximate solutions while maintaining reasonable bounds on errors. Ordinary differential equations appear in celestial mechanics planets, stars and galaxies ; numerical linear algebra is important for data analysis; stochastic differential equations and Markov chains are essential in simulating living cells for medicine and biology.
The vast majority of classical mechanics , relativity , and quantum mechanics is based on applied analysis, and differential equations in particular. Functional analysis is also a major factor in quantum mechanics. When processing signals, such as audio , radio waves , light waves, seismic waves , and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection or removal.
A large family of signal processing techniques consist of Fourier-transforming a signal, manipulating the Fourier-transformed data in a simple way, and reversing the transformation. From Wikipedia, the free encyclopedia.
