Making Roman concrete produces as much CO2 as modern concrete

arstechnica.com Unknown 2025-12-22 14:41:33

Builders in ancient Rome used a special kind of ancient concrete to construct their aqueducts, bridges, and buildings. But is Roman concrete more sustainable than the Portland cement used in today's concrete? The answer is more nuanced than one might think, according to a new paper published in the journal iScience. Roman concrete produces as much CO 2 as modern methods, but fewer air pollutants. As we've reported previously, like today's Portland cement (a basic ingredient of modern concrete),

Hill Space: Neural nets that do perfect arithmetic (to 10⁻¹⁶ precision)

news.ycombinator.com Justin Dujardin 2026-01-25 09:37:48

When understood and used properly, the constraint W = tanh(Ŵ) ⊙ σ(M̂) (introduced in NALU by Trask et al. 2018 ) creates a unique parameter topology where optimal weights for discrete operations can be calculated rather than learned . During training, they're able to converge with extreme speed and reliability towards the optimal solution. Most neural networks struggle with basic arithmetic. They approximate, they fail on extrapolation, and they're inconsistent. But what if there was a way to m

Bunker Busters probably failed to penetrate Iranian concrete

news.ycombinator.com Unknown 2026-03-01 23:02:26

On Saturday, June 21, 2025, following a spate of unprecedented aerial attacks that Israel carried out against Iran just days before, the United States joined the war and used bunker-busting bombs to strike three key Iranian nuclear sites and their underground bunkers: the Fordow fuel-enrichment plant, the Natanz nuclear facility, and the Isfahan nuclear technology center. Operation Midnight Hammer, the Pentagon’s codename for the strikes on Iran, marks the first-ever use of the Massive Ordnance
