Quantum forces used to automatically assemble tiny device

Quantum forces used to automatically assemble tiny device

[ad_1] Triangular gold flakes can be manipulated using mysterious quantum forces George Zograf Tiny gold devices for controlling light have been built using strange quantum effects that hide in seemingly empty space. In 1948, physicist Hendrik Casimir theorised that some objects experience a very weak attraction when they are held close to one another in space because of the imperceptible flickers of quantum fields in the gap between them. Researchers have since confirmed this Casimir effect in the lab. Betül Küçüköz at Chalmers University of Technology in Sweden and her colleagues have now found a way to make it useful. They wanted to build a light-trapping cavity using two pieces of gold positioned parallel to one another, between which light would bounce back and forth, unable to escape. First, they created the lower end of the cavity by imprinting a triangular gold flake between 4 and 10 microns in size onto a small piece of glass. The upper end of the cavity also comprised a triangular gold flake, but instead of holding it in place …

Power players assemble for the World Economic Forum – POLITICO

Power players assemble for the World Economic Forum – POLITICO

[ad_1] As the World Economic Forum gets underway in Davos, many of the world’s most powerful business leaders, politicians and tech gurus — and even the odd veteran pop star — have arrived in the Swiss Alps hoping to set the agenda for the year ahead.  This week we present four episodes of Power Play with an array of interviews and analysis. Today, host Anne McElvoy brings together three of POLITICO’s keenest Davos watchers to chart the week ahead. She’s joined by Alex Ward, a national security reporter based in Washington; Nahal Toosi, a senior foreign affairs correspondent; and Suzanne Lynch, author of POLITICO’s Global Playbook, your must-read each morning to keep up with the latest news from Davos. Together they’ll explore a range of topics including how the prospect of a Trump return is impacting discussions, as well as Ukraine President Volodymyr Zelenskyy’s in-person push to regain the spotlight for Kyiv.

Elon Musk reportedly rushing to assemble a rival to OpenAI

Elon Musk reportedly rushing to assemble a rival to OpenAI

[ad_1] Not satisfied with dismantling Twitter, Elon Musk is reportedly planning to take on his erstwhile ally OpenAI, and is currently attempting to collect the money and people necessary to do so. The busy billionaire may tap the resources of his several companies to accelerate the work, but there is good reason to be skeptical of this endeavor. Rumors and circumstantial evidence of Musk building an AI company to pit against OpenAI have been around pretty much since he divested from the company — which he helped fun in its early days — back in 2018. He has made no secret of disagreeing both with their choice to pursue profits rather than act as pure R&D, and also their attempt to build ethical guardrails AI, which he seems to consider too “woke.” How this perspective fits into the worldview that AI is a danger to humanity and must be limited in the long term and perhaps paused in the near term is not clear. That position may already have been abandoned, as Musk has abandoned …
