Celebrate Pi Day and read about how this number pops up across math and science on our special Pi Day page. For more than two millennia, mathematicians have produced a growing heap of pi equations in ...

Infant formula is, rightly, one of the most strictly regulated foods on the market. Formula is an essential source of nutrition for millions of infants, and it’s absolutely crucial that the formula we ...

Abstract: The virtual synchronous generator (VSG) control has been recognized for emulating key characteristics of real synchronous generators (SGs). However, most VSG desgins stem from the ...

For the unfamiliar, high-frequency facial wands “use a glass electrode filled with either argon or neon gas and a mild electrical current that passes through the gas, which creates a soft tingling ...

A high-frequency wand may offer benefits for skin appearance, including reducing fine lines or wrinkles and acne. However, more research is necessary to support these potential benefits. Using a ...

This project made me feel a kind of kinship with Diogenes, although I was searching for the item described in the title rather than for an honest man. Figure 1 “Diogenes Looking for an Honest Man,” a ...

As global power grids transition from centralized fossil-based generation to decentralized, renewable sources, system stability has become a critical challenge. The phasing out of synchronous ...

It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

A massive power outage strikes Spain and Portugal, briefly affecting parts of France as well, on Monday, April 28, 2025. Street lights, traffic signals, and internet/mobile networks go down, leading ...

Abstract: The increasing integration of inverter-based resources (IBRs) alongside traditional synchronous generators (SGs) presents new challenges for maintaining stability and resilience in modern ...
