Mathematical meaning is not captured by meaning-as-use
In "Mathematical meaning is not captured by meaning-as-use," Phoebe Klett and W. J. Zeng argue that Wittgenstein's concept of meaning-as-use, while effective for language models, falls short for mathematical and symbolic reasoning. They assert that mathematical meaning is intrinsically tied to the physical world, not just its linguistic representations. The authors highlight that while language models can learn from context, they struggle with mathematical tasks because these require an understanding of the world itself. They propose that to truly grasp mathematical meaning, systems need access to physical reality, either through embodiment or simulation. This perspective challenges the view that mathematical meaning is purely syntactical, emphasizing the importance of the physical world in understanding mathematics. The unique insight here is the suggestion that mathematical understanding is deeply rooted in the physical universe, which could explain the "unreasonable effectiveness" of mathematics in modeling reality.

War-era sugar rationing boosted health of UK people conceived in 1940s
During World War II, the UK implemented sugar rationing, which unexpectedly improved the long-term health of individuals conceived during that era. Research led by Tadeja Gracner at the University of Southern California found that those exposed to lower sugar intake in the womb had a significantly reduced risk of developing type 2 diabetes and hypertension later in life. This suggests that early-life sugar consumption impacts adult health, potentially through epigenetic changes or lifelong dietary preferences. While the study highlights the benefits of reduced sugar intake, Scott Montgomery from Örebro University posits that overall lower calorie consumption during rationing might also contribute to these health benefits. Despite current dietary guidelines recommending similar sugar levels to wartime rations, actual consumption remains much higher, underscoring the need for reduced sugar intake. The study cleverly uses historical rationing as a natural experiment, though the exact causal mechanisms remain debated.
