    An AI System has reached Human Level on a Test for ‘General Intelligence’—here’s what that means

    December 26, 2024, Categories  Physics, Technology/Electronics

    A new artificial intelligence (AI) model has just achieved human-level results on a test designed to measure “general intelligence.”

    On December 20, OpenAI’s o3 system scored 85% on the ARC-AGI benchmark, well above the previous AI best score of 55% and on par with the average human score. It also scored well on a very difficult mathematics test.

    Creating artificial general intelligence, or AGI, is the stated goal of all the major AI research labs. At first glance, OpenAI appears to have at least made a significant step towards this goal.

    While skepticism remains, many AI researchers and developers feel something just changed. For many, the prospect of AGI now seems more real, urgent and closer than anticipated. Are they right?

    Twisted Edison: Filaments Curling at the Nanoscale Produce Light Waves that Twirl as they Travel

    Behind the bulb, a screen displays the temperature of the glowing filament. The wavelengths of light emitted by the filament depend on its temperature, and how well the filament twirls the light depends on how close the wavelengths are to the pitch of the filament’s twists.

    Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers at the University of Michigan have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.

    “It’s hard to generate enough brightness when producing twisted light with traditional ways like electron or photon luminescence,” said Jun Lu, an adjunct research i...

    A crystal with 171Yb+ -172Yb+ ions is trapped in an ultra-high vacuum system. The researchers use different lasers to perform the simulation: one pair of lasers (indicated by the purple arrows) is used to simulate the coherent part of the evolution, while another laser (the blue arrow) is used to simulate and control the environment.
