The oblique helicoidal cholesterics can precisely reflect light at specific wavelengths (bandwidth < 30 nm) by adjusting the internal layered structure gap in response to external stimuli, such as ...

It seems there was a bend somewhere that caused this. [Limpkin] did get around the issue by using a helicoidal coupler. This small success finally got his mill up and running. So this Fail post ...

The watches also incorporate a new shock-absorbing system consisting of helicoidal stainless steel springs between the movement and the case that are crafted by laser and offer better elasticity.

It's fundamental that architects know about structures, not only to bring their designs to reality but also to be able to discuss their projects with engineers in order to find the best solutions ...

doubled back on itself like a helicoidal twist. If you can’t find them – though they’re very much worth seeking out – then substitute casarecce or, easier still, fusilli.
