Weyl integration formula

Okay kiddo, so there's a thing called integration which helps us add up little pieces of something to get the total of everything. It's like if you have a bunch of Legos and you want to know how many Legos you have in total, you can count them one by one or you can group them into sets and add up the sets. Integration is like grouping the Legos and adding up the sets.

Now, there's a man named Hermann Weyl who came up with a special way of doing integration called the Weyl integration formula. This formula helps us add up not just regular numbers like 1, 2, 3 but something called eigenvalues.

Eigenvalues are like special numbers that tell us about something called a matrix. A matrix is like a big table of numbers that helps us do some special math called linear algebra. It's like if you have a bunch of numbers and you want to know how they relate to each other, you can put them in a matrix.

Now, the Weyl integration formula helps us add up all the different eigenvalues in a matrix. It's like if you have a big table of numbers and you want to know the total sum of all the numbers in it, you can use the Weyl integration formula to help you.

So basically, the Weyl integration formula is a special way of doing integration that helps us add up eigenvalues in a matrix, which is like a big table of numbers that helps us do some special math called linear algebra.
