Most lasers are either friendly tabletop devices or so small that you don’t even notice them. But if you want to do something special like image the structure of a delicate protein, you need a very short wavelength and very high-power laser. That means a free electron laser (FEL).

I love FELs, but they’re expensive. A laser produces one beam, and that beam is usually limited to one or two users at a time. So competition for beam time at FELs is fierce. That may be about to change, though. An unexpected experimental result at the Linac Coherent Light Source may be the key to making multiple beams from a single FEL undulator line.

Enough gibberish

OK, time for some physics-to-almost-English translation. Let’s start with some FEL goodness.

Fractals are a source of endless fascination to me. Life itself relies on many of the concepts of fractals: trees are fractal, as are feathers, coast lines, and many other things in nature. Indeed, it was the realization that landscapes are fractal that made modern animated films possible.

But, what about fractional dimensions in quantum mechanics? It turns out that electrons in a Sierpiński gasket are also fractal, and that has some pretty cool consequences.

A fractal is a weird beast. A line is 1D, a square is 2D, and a cube is 3D: dimensions come in integer quantities. Except they don’t. For instance, it is possible to create a shape that has a finite area, but a perimeter that is infinitely long (the construction of such a shape is pictured below). A shape with these properties does not behave like a 2D object, but it’s not a 3D object. Instead, it is a two-and-a-bit-D object. That is a fractal.

Neural networks have a reputation for being computationally expensive. But only the training portion of things really stresses most computer hardware, since it involves regular evaluations of performance and constant trips back and forth to memory to tweak the connections among its artificial neurons. Using a trained neural network, in contrast, is a much simpler process, one that isn’t nearly as computationally complex. In fact, the training and execution stages can be performed on completely different hardware.

And there seems to be a fair bit of flexibility in the hardware that can be used for either of these two processes. For example, it’s possible to train neural networks using a specialized form of memory called a memristor or execute trained neural networks using custom silicon chips. Now, researchers at UCLA have done something a bit more radical. After training a neural network using traditional computing hardware, they 3D printed a set of panels that manipulated light in a way that was equivalent to processing information using the neural network. In the end, they got performance at the speed of light—though with somewhat reduced accuracy compared to more traditional hardware.

So how do you implement a neural network using light? To understand that, you have to understand the structure of a deep-learning neural network. In each layer, signals from an earlier one (or the input from a source) are processed by “neurons,” which then take the results and forward signals on to neurons in the next layer. Which neurons they send it to and how strong a signal they pass on are determined by the training they’ve undergone.

The 2017 Kia Optima PHEV adds plug-in capability and EV-only operation to the Optima hybrid’s already well-rounded attributes and agreeable personality. That said, its familiar shape does get a few touches shared with the Optima hybrid that are aimed at reducing drag: a slightly redesigned, model-specific front fascia with active grille shutters that close at speed, a reshaped rear bumper with a rear diffuser that shrouds the exhaust tip, and a more aerodynamic wheel design.
