When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...
Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...
In his discussion of accelerated motion on page 60 of "The Meaning of Relativity," Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein ...
Out with the old: Many undergraduate physics curricula need revamping. (Courtesy: iStock/Pobytov) Physics education has a high inertia towards change. While high-school students in today’s biology ...
A pair of scientists from the UK recently published a pre-print research paper discussing the theory of a universe with no beginning. Imagine it: our universe has always existed. The Big Bang either ...
If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...
Physicists in Australia have become the first researchers to levitate a macroscopic object using lasers. The physicists used three lasers to form a levitational "tripod" that could hold a small mirror ...
Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...
