Many people think that mathematics is a human invention. To this way of thinking, mathematics is like a language: it may describe real things in the world, but it doesn’t “exist” outside the minds of the people who use it.

But the Pythagorean school of thought in ancient Greece held a different view. Its proponents believed reality is fundamentally mathematical. More than 2,000 years later, philosophers and physicists are starting to take this idea seriously.

As I argue in a new paper, mathematics is an essential component of nature that gives structure to the physical world.

Keeping up with the first law of robotics: a new photonic effect for accelerated drug discovery. Physicists at the University of Bath and University of Michigan demonstrate a new photonic effect in semiconducting nanohelices. A new photonic effect in semiconducting helical particles with nanos.

California has more rooftops with solar panels than any other state and continues to be a leader in new installations. It is also first in terms of the percentage of the state’s electricity coming from solar, and third for solar power capacity per capita. However, former California governor Arnold Schwarzenegger has expressed concerns that California.

California has more rooftops with solar panels than any other state and continues to be a leader in new installations. It is also first in terms of the percentage of the state’s electricity coming from solar, and third for solar power capacity per capita. However, former California governor Arnold Schwarzenegger has expressed concerns that California solar — once the model for other US states — is on a precipice. In an opinion piece for the New York Times this week, Schwarzenegger has unpacked a new California Public Utilities Commission proposal which, if approved, would discourage progress being made in the transition to clean energy and grid resilience.

What’s the problem, then? The California Public Utilities Commission is threatening solar progress. But this “hard-earned and vitally important accomplishment” may succumb as the Commission considers a plan that has the potential to make California solar too costly for its citizens.

ASML President and CTO Martin van den Brink said:

“Intel’s vision and early commitment to ASML’s High-NA EUV technology is proof of its relentless pursuit of Moore’s Law. Compared to the current EUV systems, our innovative extended EUV roadmap delivers continued lithographic improvements at reduced complexity, cost, cycle time and energy that the chip industry needs to drive affordable scaling well into the next decade.”

Intel plans to start high-volume manufacturing (HVM) in 2025, which is also when the company will be using its 18A (1.8nm) fabrication technology. To do so, Intel has been experimenting for quite a while when it first obtained ASML’s Twinscan EXE:5000, which was the industry’s first EUV scanner with a 0.55 numerical aperture. Today, the company ordered ASML’s next-generation High-NA tool, the Twinscan EXE:5200.

High-tech missiles, sensors, aircraft, ships, and artillery all rely on atomic clocks on GPS satellites for nanosecond timing accuracy. A timing error of just a few billionths of a second can translate to positioning being off by a meter or more. If GPS were jammed by an adversary, time synchronization would rapidly deteriorate and threaten military operations.

To address this scenario, DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size, weight, and power (SWaP) that yield timing accuracy and holdover better than GPS atomic clocks and can be used outside a laboratory. ROCkN will leverage DARPA-funded research over the past couple decades that has led to lab demonstration of the world’s most precise optical atomic clocks. ROCkN clocks will not be as precise as the best lab optical clocks, but they will surpass current state-of-the-art atomic clocks in both precision and holdover while maintaining low SWaP in a robust package. https://www.darpa.mil/news-events/2022-01-20

At this rate the CCP will be launching everyday by the end of the decade. Wow.

China became the country that has carried out the most space launch missions in the world over the past year.

The country’s Long March series carrier rockets, Kuaizhou series carrier rockets, as well as those developed by private space firms have made 55 launches and sent over 100 spacecraft into space.

This tiny galaxy has a huge black hole at its center that’s churning out stars.

Scientists observed a black hole birthing new stars in a dwarf galaxy for the first time, providing evidence as to how these all-consuming objects can create stellar nurseries. The observations also reveal how ancient black holes may have formed shortly after the Big Bang.

The findings are detailed in a study published Wednesday in the journal Nature.
