"current computational techniques time-consuming/ expensive, overcome by encoding equations in light wave's intensity property, then phase feeding them into diffractive optical neural networks/ optical matrix multipliers... as wave passes through, intensity gradually shifts/ changes until representing solution... takes the spatiotemporal data of an input physical quantity, which is a function of positions and time, to predict the spatiotemporal data of an output physical quantity as a function of positions and time"
