The cookbook author Kenji López-Alt dives deep into a question of his own, with computer models and all.

The Takeaway
The most efficient, even way to dice an onion is to trim off the top, split it in half, peel it, then lay one half down on a cutting board.

If we call the radius of the onion one (that is, its height above the cutting board as it’s lying flat on its cut surface), you’ll want to start with a series of vertical cuts made with your knife aimed toward an imaginary point about .6 of an onion’s height below the surface of the cutting board.

Follow that up with a single horizontal slice and a series of crosswise vertical slices to divide it into dice.

I know how I like to do it and it's none of the methods described. What I found most interesting is the fact that the target point in their optimized cutting technique is the reciprocal of the square root of 3.
I'd like to see the function they were optimizing to see why that particular irrational number arose as the result.

I’m just happy I don’t cut my fingers. The onions get cooked, we eat, all is good.
