The fourth state of matter, plasma, is involved in several aspects of how modern microelectronic components are manufactured. Jeremiah Williams, a professor at Wittenberg University and a program director at the U.S. National Science Foundation, discusses how plasmas are used in semiconductor manufacturing and how understanding plasma physics spurs industrial innovation.

Small tremor of magnitude 2.7 just reported 5 km northeast of Fira, Greece

An earthquake of magnitude 2.7 occurred only 14 minutes ago 5 km northeast of Fira, Greece, the National Observatory of Athens (NOA) reported.
The quake hit at a very shallow depth of 5. km beneath the epicenter near Fira, Kykládes, South Aegean, Greece, late at night on Monday, July 21st, 2025, at 11:04 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by The Aristotle University of Thessaloniki Geophysical Lab. (AUTH), which listed it as a magnitude 2.7 earthquake as well. Other agencies reporting the same quake include The Seismological Laboratory of the University of Athens (UOA) at magnitude 2.8, and the citizen-seismograph network of RaspberryShake at magnitude 2.7.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Monolithos (pop. 180) located 2 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Fira (pop. 2,400) located 5 km from the epicenter,
