The Obtain: AI’s math options, and brewing beer with daylight

[ad_1]

AI fashions can simply generate essays and different varieties of textual content. Nevertheless, they’re nowhere close to nearly as good at fixing math issues, which are likely to contain logical reasoning—one thing that’s past the capabilities of most present AI techniques.

However that will lastly be altering. Google DeepMind says it has skilled two specialised AI techniques to unravel complicated math issues involving superior reasoning. The techniques labored collectively to efficiently remedy 4 out of six issues from this yr’s Worldwide Mathematical Olympiad, a  prestigious competitors for highschool college students.

They received the equal of a silver medal, marking the primary time any AI system has ever achieved such a excessive success price on these sorts of issues. Learn the total story.

Why the US continues to be making an attempt to make mirror-magnified photo voltaic power work

The US is continuous its decades-long effort to commercialize a know-how that converts daylight into warmth, funding a collection of latest initiatives utilizing that power to brew beer, produce low-carbon fuels, or maintain grids working.

The Division of Vitality has introduced it’s placing $33 million into 9 pilot initiatives primarily based on concentrating photo voltaic thermal energy, MIT Expertise Evaluation can report solely. The know-how makes use of massive arrays of mirrors to pay attention daylight onto a receiver, the place it’s used to warmth up molten salt, ceramic particles, or different supplies that may retailer that power for prolonged durations.
