What Does It Mean for AI to Understand?

Remember IBM’s Watson, the AI Jeopardy! champion? A 2010 promotion proclaimed, “Watson understands natural language with all its ambiguity and complexity.” However, as we saw when Watson subsequently failed spectacularly in its quest to “revolutionize medicine with artificial intelligence,” a veneer of linguistic facility is not the same as actually comprehending human language. Natural language… Continue reading What Does It Mean for AI to Understand?

A Wrinkle in Nature Could Lead to Alien Life – Issue 111: Spotlight

I grew up in a small village in a very rural part of England. It was a landscape capped with the huge skies of a low-lying coastal zone. Gently rolling fields, long hedgerows, and a lot of farms.

Detailed Footage Finally Reveals What Triggers Lightning

So Dwyer and his team turned to the Low Frequency Array (LOFAR), a network of thousands of small radio telescopes mostly in the Netherlands. LOFAR usually gazes at distant galaxies and exploding stars. But according to Dwyer, “it just so happens to work really well for measuring lightning, too.” When thunderstorms roll overhead, there’s little… Continue reading Detailed Footage Finally Reveals What Triggers Lightning

Astrophysicists Unveil Glut of Gravitational-Wave Detections

Gravitational-wave observatories have released their latest catalogue of cosmic collisions, bringing their total number of detections to 90. The new crop of 35 events includes one featuring the lightest neutron star ever seen, as well as two clashes involving surprisingly large black holes. The detections come from the two Laser Interferometer Gravitational-Wave Observatory (LIGO) sites,… Continue reading Astrophysicists Unveil Glut of Gravitational-Wave Detections
