Quantum theory was born in 1900 with an important paper by Max Planck on black-body radiation. In this paper, he introduced quanta of vibrational energy E which are proportional to their frequency ν, and his famous constant currently known to take...

The atomic model proposed by Niels Bohr in 1913 was an important milestone in the history of science for two quite different reasons. First, the Bohr theory answered some fundamental questions about the location and behavior of electrons in an atom. In...

Quantum theory is the basis of the modern understanding of most branches of physics. At the turn of the twentieth century, many physicists assumed that physics was almost totally figured out, with only a few small problems left to be solved. These...

Quantum physics is based on quantum theory. The first idea about quantum theory was from Max Planck in 1900. He proposed that energy was not emitted continuously but rather in quanta in black body radiation. He was awarded the 1918 Nobel Prize in...

Quantum computing is such an elusive goal that even the company claiming to have the "world's first commercial quantum computer" acknowledged it isn't entirely sure the machine is performing true quantum calculations.And independent quantum computing researchers said they are dubious of some of the claims...

Dear Theoretical Physicist: I met a terrific girl a few months ago, and things are starting to become serious. I like her very much, but she wants children quickly and I still don’t feel ready. What should I do? —Alexander F., East Village Dear Alexander:...

In this first part of a series of essays on quantum physics, I will explore topics on light, space, and time. According to relativity, it is said and proven that something with mass which approaches light-speed gradually gets smaller in the view of others, as it is mentioned that any moving object's (with mass) length decreases proportionately to its speed in the direction it was moving until it reaches zero at light-speed.
