I invented Matrix in 1960.

It was published as Matrix in 1972 in Genii Magazine.

Since then there are countless routines called Matrix. Why?

The trick grew from a trick in Bobos book called Sympathetic Coins.

Why not call them Sympathetic Coin routines instead? The basic plot is even older. Chink-a-Chink is essentially the same effect and is far older. Why arent they called Chink-a-Chink routines instead? Yes, it used something extra that appeared as a shell. So do many present day Matrix routines?

The basic difference from Sympathetic Coins is that Matrix uses four cards instead of two. It could be said that that Sympathetic Coins consisted of penetrations and one transposition. On the other hand the moves of many Matrix routines differ so much from the Classic Matrix routine; penetrations do not seem to be that much different from what is now done.

Even coin routines using no cards are called Matrix. Many say, as I do, that these are not appropriate to call Matrix routines. But many build routines that resemble the initial plot little but are still called Matrix.

Why is this?

It has been said that Shadow Coins is a trick far superior than Matrix. Why arent these tricks then called Shadow Coin variations?

A guy named John Kennedy marketed a trick called Matrix. Some years ago I bumped into him and asked him why he is calling his trick Matrix since I published a trick called Matrix years previous. He said, Matrix is a public name! This is a peculiar response considering his trick used three cards covering three coins. Apparently he did not understand the mathematical sense of the word matrix. Someone came out with a book called, Matrix, Gods Way. I saw the routine. Hmmmmmm.

What is going on?
