Absolutely. I do not know the current status, so don’t kill me if now is much better, because is just an example from many. But take fourier series. I remember going into the article, and instead of starting with something lime “helps to decompose functions in sums of sin and cos”, started with “the forier transform is defined as (PUM the integral for with Euler formula) continues: is easy to show the integral converges according to xxx criterion, as long as the function is…” you get the idea. Had I not know what FT is, I would’ve not undestand anything Articles in biology, from which I understand nothing, are a wall for me. I could never understand anything biology related. Also for example, in Spanish, don’t ask me why, any plant or animal is always under the latin scientific name, and you have to search the whole article to find the “common” name of the thing. |

> A Fourier series is a series expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series. By expressing a function as a sum of sines and cosines, many problems involving the function become easier to analyze because trigonometric functions are well understood.

> In mathematics, the Fourier transform (FT) is an integral transform that takes a function as input, and outputs another function that describes the extent to which various frequencies are present in the original function. The output of the transform is a complex valued function of frequency. The term Fourier transform refers to both the mathematical operation and to this complex-valued function. When a distinction needs to be made, the output of the operation is sometimes called the frequency domain representation of the original function. The Fourier transform is analogous to decomposing the sound of a musical chord into the intensities of its constituent pitches.
