Adox

A photographer shared a 35mm film image of Prague marking the end of the sunny season, shot on a Pentax ME Super with Kentmere 400 film pushed one stop and developed in Adox XT-3 chemistry. The picture is resonating with film photography enthusiasts who appreciate analogue techniques and seasonal city scenes.

A new analysis argues that armed forces worldwide are acquiring advanced technology faster than their institutions can adapt. The piece contends that modernization programs focused on hardware often stall because doctrine, training, bureaucracy and organizational culture lag behind, leaving militaries with sophisticated equipment but outdated structures. It warns that closing this institutional gap is as critical as the technology itself for real military effectiveness.

A new article examines the black hole information paradox, explaining why quantum unitarity conflicts with Hawking's thermal radiation and how the Page curve frames the problem. It also covers island and replica-wormhole calculations that reproduce the Page curve in simplified models, along with firewall arguments and the ER=EPR conjecture, offering a consolidated overview of recent theoretical progress.

Iran's science olympiad system trains some of the world's brightest students in physics and mathematics, yet many medalists ultimately emigrate for better opportunities abroad. The pattern highlights a gap between the country's investment in elite scientific education and its ability to retain that talent, raising questions about brain drain from Iran's universities and research institutions.

The 1935 Einstein-Podolsky-Rosen paradox argued that quantum mechanics was incomplete. In 1964, John Bell showed the question could be tested experimentally. Experiments between 1972 and 2015, including a Delft test measuring entangled electron spins 1.3 kilometres apart, found correlations that no local hidden variable theory can explain, settling the debate in favour of quantum mechanics.

HydraX, a deep-tech startup, is weighing whether to enter a first market that could be stronger commercially but demands significantly more research and development before launch. The case highlights a common tension for deep-tech founders: the most promising market opportunity may not be the fastest or cheapest path to a first product, forcing trade-offs between timing, funding and technical readiness.
