Atomic Hydrogen Welding
Atomic hydrogen welding (AHW) is a welding technology invented in the early twentieth century, primarily for combining metals such as aluminum and magnesium. It is…
Variable-frequency Transformer (VFT)
A variable-frequency transformer (VFT) transmits electricity between two (asynchronous or synchronous) alternating current frequency domains. A Variable-Speed Drive (VSD) or Adjustable-Frequency Drive (AFD) is a…
Mathematical Developments enable Advancements in Seismic Activity Detection
Scientists have overcame mathematical hurdles in traditional Spectral Matrix analysis, which is used to evaluate three-component seismic signals, by incorporating time-delay components. The novel technology…
Quantum Tornadoes give a path to Comprehending Black Holes
Scientists have generated a gigantic quantum vortex in superfluid helium to simulate a black hole, allowing them to study in greater detail how simulated black…
Tesla Coil
Nikola Tesla invented the Tesla coil, which is an electrical resonant transformer circuit, about 1891. It is used to generate high-voltage, low-current, high-frequency alternating current…
Spark-gap Transmitter
A spark-gap transmitter is an early type of radio transmitter that generates radio waves to communicate. It is an old type of radio transmitter that…
How an Ignition Coil Works
An ignition coil is an essential part of an internal combustion engine’s ignition system. It is used in the ignition system of a spark-ignition engine…
New Detecting System Tries to Warn about Landslides and Tsunamis
Researchers at the University of Alaska Fairbanks have developed a method for remotely detecting massive landslides within minutes of their occurrence and determining whether they…
Root Microorganisms might be the key to a better Tasting Cup of Tea
You’d expect that the rich flavor of a high-quality cup of tea would be mostly determined by the tea kinds utilized. However, a study published…
Urban Climatology
Urban climatology is the study of urban climates. It is a subfield of climatology that investigates climate in urban contexts. It is a subfield of…
Oceanic Trenches
Oceanic trenches are long, narrow, and very deep depressions in the ocean floor. They are the deepest sections of the Earth’s oceans, generated mostly by…
