To gain new insight, astronomers plan to observe a spiral galaxy that hosts a supermassive black hole at its center. They will gather the data through NASA’s James Webb Space Telescope, which is set to be launched in 2021. By evaluating...
Lasers are intense beams of concentrated light. These beams are powerful enough to cut through lumps of metal and zoom miles into the sky. Although laser technology seems new, it has been with us for nearly six decades: the first practical laser was...
Although Alexander Graham Bell is generally credited for inventing the telephone, it was the culmination of research done by many individuals. Antonio Meucci, Johann Philipp Reis, Innocenzo Manzetti, and Elisha Gray made significant contributions...
Roller coasters are a staple for amusement parks and theme parks around the world. It won’t be wrong to say that an amusement park is incomplete without a roller coaster. They are a popular source of entertainment. But have you ever wondered...
