Scientists set the stage for quantum chemistry in space on NASA’s cold atom lab

Posted by in categories: biotech/medical, chemistry, mobile phones, quantum physics

For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA’s Cold Atom Laboratory aboard the International Space Station, the achievement marks another step toward bringing quantum technologies currently available only on Earth into space.

Physicists at Leibniz University Hannover (LUH), part of a collaboration led by Prof. Nicholas Bigelow, University of Rochester, provided the theoretical calculations necessary for this achievement. While quantum tools are already used in everything from cell phones to GPS to , in the future, quantum tools could be used to enhance the study of planets, including our own, as well as to help solve mysteries of the universe and deepen our understanding of the fundamental laws of nature.

The new work, performed remotely by scientists on Earth, is described in Nature.

From concrete quarks to QCD: a personal perspective

Posted by in categories: materials, particle physics

The simple story line that ‘Gell-Mann and Zweig invented quarks in 1964 and the quark model was generally accepted after 1968 when deep inelastic electron scattering experiments at SLAC showed that they are real’ contains elements of the truth, but is not true. This paper describes the origins and development of the quark model until it became generally accepted in the mid-1970s, as witnessed by a spectator and some-time participant who joined the field as a graduate student in October 1964. It aims to ensure that the role of Petermann is not overlooked, and Zweig and Bjorken get the recognition they deserve, and to clarify the role of Serber.

Meta-reinforcement learning via orbitofrontal cortex

Posted by in category: robotics/AI

The authors show that neural activity and synaptic plasticity in the orbitofrontal cortex mediate multiple timescales of reinforcement learning (RL) for meta-RL, which parallels a form of meta-RL in artificial intelligence.

“Make It Real” AI prototype wows devs by turning drawings into working software

Posted by in categories: robotics/AI, security

On Wednesday, a collaborative whiteboard app maker called “tldraw” made waves online by releasing a prototype of a feature called “Make it Real” that lets users draw an image of software and bring it to life using AI. The feature uses OpenAI’s GPT-4V API to visually interpret a vector drawing into functioning Tailwind CSS and JavaScript web code that can replicate user interfaces or even create simple implementations of games like Breakout.

Users can experiment with a live demo of Make It Real online. However, running it requires providing an API key from OpenAI, which is a security risk. If others intercept your API key, they could use it to rack up a very large bill in your name (OpenAI charges by the amount of data moving into and out of its API). Those technically inclined can run the code locally, but it will still require OpenAI API access.

OpenAI CEO Sam Altman wants to build AI “superintelligence”

Posted by in categories: finance, robotics/AI

OpenAI plans to secure further financial backing from its biggest investor Microsoft as the ChatGPT maker’s chief executive Sam Altman pushes ahead with his vision to create artificial general intelligence—computer software as intelligent as humans.

In an interview with the Financial Times, Altman said his company’s partnership with Microsoft’s chief executive Satya Nadella was “working really well” and that he expected “to raise a lot more over time” from the tech giant among other investors, to keep up with the punishing costs of building more sophisticated AI models.

Emmett Shear Becomes Interim OpenAI CEO as Altman Talks Break Down

Posted by in category: robotics/AI

Breaking: sam altman will not return as CEO of openai.


Sam Altman won’t return as CEO of OpenAI, despite efforts by the company’s executives to bring him back, according to co-founder and board director Ilya Sutskever. After a weekend of negotiations with the board of directors that fired him Friday, as well as with its remaining leaders and top investors, Altman will not return to the startup he co-founded in 2015, Sutskever told staff. Emmett Shear, co-founder of Amazon-owned video streaming site Twitch, will take over as interim CEO, Sutskever said.

The decision—which flew in the face of comments OpenAI executives shared with staff on Saturday and early Sunday—could deepen a crisis precipitated by the board’s sudden ouster of Altman and its removal of President Greg Brockman from the board Friday. Brockman, a key engineer behind the company’s successes, resigned later that day, followed by three senior researchers, threatening to set off a broader wave of departures to OpenAI’s rivals, including Google, and to a new venture Altman has been plotting in the wake of his firing.
