Why Sub-Zero Temperature Water Doesn't Become Ice

Water behaves in mysterious ways, especially below zero before it turns into ice. Physicists have recently observed the spontaneous first steps of the ice formation process, as tiny crystal clusters as small as 15 molecules start to exhibit the recognizab ...

Bang!! 13 TeV- The Highest Energy Ever Achieved By Mankind?!

The LHC has finally started to produce 13-TeV proton-proton collisions! The picture below shows one such collision, as recorded by the CMS experiment today. The blue boxes show the energy recorded in the calorimeter, which measures particle energy by " ...

Highest Energy Collisions? Not In My Book

Yesterday I posed a question- Are the first collisions recorded by the LHC running at 13 TeV the highest-energy ever produced by mankind with subatomic particles? It was a tricky one, as usual, meant to think about the matter. I received several tentative ...

2nd law of thermodynamics

Here is a wordy topic which also happens to be rich with physics and foundational in almost every aspect of engineering.   The 2 nd law of thermodynamics states that, you cannot build a device capable of extracting heat from something to do work without h ...

No Sign of Quantum Space-Time Foam from Quasar Light.

M ost models of quantum gravity propose or predict that at very short distances space is a frothing foam where distance and time intervals themselves fluctuate rapidly.  These models predict that if light can travel long distances there will be a cumulati ...

Conservation Of Energy

There are multiple conservation laws in nature meaning these are considered to be scientific truths which are fundamental and foundational to all modern science as we know it. Perhaps the most familiar or common conservation law in science is that of the c ...

Green Rays: Rare, From The Sun; And From The Moon?

The light we receive from the sun is composed of all visible frequencies, among others, and it therefore appears white to our natural detection system- the human eye. Apparently, evolution caused us to develop a vision which works best at the center of th ...

Is The New LHC Run The End Of Particle Physics As We Know It?

Physicists around the world (myself included) are hoping that this week will mark the beginning of a new era of discovery. And not, as some fear, the end of particle physics as we know it. After 27 months of shutdown and re-commissioning, the Large Hadron ...
