The race to invest in high-end AI chips | DW Business

They are tiny, they are mighty – and they power the modern world. Computer chips run everything from our smartphones to our dishwashers. Over the years they’ve become ever more powerful – and today, it is their potential to steer Artificial Intelligence that is generating the most attention. But there’s a problem. Producing these super advanced chips is extremely expensive. And that is why Sam Altman – the founder of Open AI – that’s the company behind Chat GPT – is calling for a $7 trillion investment in the industry. DW Business speaks to Chris Miller, Associate Professor of International History at The Fletcher School and the author of a book called “Chip War.”

This Toxic, Drying U.S. Lake Could Turn Into the ‘Saudi Arabia of Lithium’ | WSJ

California’s toxic Salton Sea is a treasure trove of lithium – a critical ingredient for powering the country’s clean energy future. The estimated 18 million metric tons of lithium suspended in hot geothermal brine is enough to power more than 375 million EV batteries. So what kinds of new tech are companies using to get to this lithium despite the corrosive conditions? WSJ takes you behind the scenes to understand how companies are building entirely new ways to extract lithium from the area and what it means for the future of domestic lithium production.

Quantum simulation of a particle scattering in a lattice

The video shows a quantum simulation made by solving the Schrödinger equation for a particle scattering in three different lattices.

It can be seen that despite the complex behavior within the periodic lattice, the diffracted wavefunction at the output is well resolved, a well-known fact in electron crystallography.

This made QMsolve, an open-source python open-source package for visualizing and solving the Schrödinger equation.
