On this occasion, it is worth our time to consider a striking paradox in many organizations today, which can be understood through the lens of how a train operates.

This week on Behind The Lens, Louisiana reclassifies natural gas as “green energy” under a controversial new law signed by Gov. Jeff Landry. We also examine a major expansion of ammonia plants in ...

Conical in shape Fresnel zone (CFZ) lens of flat dielectric rings is introduced and studied in this research. It is contrasted to a plane Fresnel zone (PFZ) lens, a CFZ lens of conical rings and a ...

High-performance, ultracompact lenses are needed in the quest to miniaturize optical systems. It now seems that carefully engineered subwavelength gratings can function as almost perfect mirrors ...

In this study, we expressed recombinant αA- and αB-crystallin in E. coli and compared the polydispersity, structure and aggregation state between each other and native bovine lens α-crystallin.

I reckon the Sigma 17-40mm f/1.8 DC | A is a pretty epic lens. I’m not a fan of ‘trinity’ f/2.8 zooms for full-frame cameras as they’re generally big, heavy, expensive and not really that fast, ...
