The New Petzval (D)SLR Lens
Lomography's New Petzval Art Lens — a reimagined version of Josef Petzval's 1840 portrait lens design, crowdfunded on Kickstarter for DSLR and SLR cameras. Known for its distinctive swirly bokeh and sharp central focus characteristic of the original Petzval optical formula.
5D 'Superman Memory' Crystal — Unlimited Lifetime Data Storage
University of Southampton researchers demonstrated 5D optical data storage in quartz glass using femtosecond laser writing — 360 TB per disc, theoretically stable for billions of years. An early result from the lab that eventually led to Project Silica.
Physicists Store a Two-Frame Movie in an Atomic Cloud
NIST researchers stored two sequential image frames — a functional two-frame 'movie' — inside a cloud of ultracold rubidium atoms using quantum optical techniques. A proof-of-concept for quantum memory, storing light itself as atomic spin states.
