Gamma Ray Spectroscopy - An introductory review of germanium gamma ray detectors, and the spectroscopic methods used in the measurement of x-ray escape peaks, annihilation photons, peak summing, energy resolution, and total and photopeak efficiency.

Why are high energy particle accelerators, such as the LHC at CERN, required to study modern particle physics? What are the different types of particle accelerator? Do particle accelerators have other benefits to society outside of scientific research?

So many different versions to consider. Will you be the one to come up with a new solution?

The mathematical notion of "nothing" is actually quite enormous. There is more emptiness in the universe than there is physical substance. Follow along with me as I clarify this concept.

TRIUMF is a facility for research in particle physics and accelerator-based science. It contains the largest cyclotron in the world and produces medical isotopes.

Time is a real component of physical reality, non-spatial and immaterial. It's a core dimension of the universe, underlying change and causation. Time is unique and indispensable, embedded in everyday experience and science's conceptualization of the universe.

Do you believe that time exist, or do you believe that it is an idea in our minds?

Sound is a physical and psychological experience. If the brain goes without stimuli, it will produce its own in the form of hallucinations. Even deaf people experience tinnitus, but is this technically sound. This article defines sound and examines what an experience of true silence might be like.

Galileo not only spotted new objects in the sky but also laid the groundwork for advancements in physics. What were they?

Sounds made up, doesn't it? But in reality, it could be a missing key to physics.

With billions of galaxies in the universe that may have the potential for Earth-like planets in their solar systems, the chance of intelligent life elsewhere must exist. But there are reasons why we may never find it.

Quantum Mechanics is quite intimidating but also very intriguing. However, the whole quantum theory stands on the shoulders of Heisenberg's Uncertainty Principle. Let's see its perilous existence and the need of Heisenberg's Uncertainty Principle.

Physics aims to give elegant explanations for the phenomena observed within in our universe. These explanations are encoded in the mathematical language of equations. What are the most important and beautiful equations in physics?

Students have an excellent chance of doing well on a physics exam if they work efficiently throughout the physics course and follow some tips for writing exams.

Are atomic bombs ethical? This article debates the morality and ethical principles that surround the controversy about nuclear weapons.

Why does time only go forward? Is there some kind of gravity that relates to time? The gravity of time, or time gravity, is my theory that affects the direction of time—keeping it going only in one direction.
