First predicted in the 1960s, like the Higgs boson before it, the pentaquark eluded science for decades until its recent detection at CERN’s LHCb collaboration. The discovery amounts to finding a new form of matter…
1/60 minute. 1/3,600 hour. 1/86,400 day. 1/1 hertz. The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of a 133 55Cs caesium isotope corresponds to one second. But what does it look like? And where might you find a second?

Deep down, in huge subterranean caverns… Underneath the Franco-Swiss border… 300 feet underground… lies a beast of unprecedented power… and mystery. The Large Hadron Collider (LHC) that man summons to explore the uncharted corners of the sub-atomic realm… After two years of a deep slumber, the mighty beast has awoken…

The Standard Model of Particle Physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces, providing precise predictions for measurable quantities that can be tested experimentally. Here’s the latest!! It’s hot!!! It’s exciting!!! At least, if you’re a particle physicist…

Should you ever have wondered what the Higgs boson sounds like… It’s… “AS LOUD AS A RIFF BY JOE SATRIANI. WHAT?! IT’S AS LOUD… AS A…” Oh, wait!! Here it is.

“Dark matter?” You cannot see it. But there is something there. As for what it is, it’s anybody’s guess! Dark matter does not interact with light. At all. Which makes it difficult to detect. “But if you cannot see it? How do you know it is in fact there?” Well, it does interact with gravity, and as it does so it bends the path of any light ray passing nearby...

That’s how this TED video on the Higgs boson begins. I say two guys… It’s more like one physicist working on the Large Hadron Collider at CERN – the European laboratory for Particle Physics – aka Dave Barney, and a Blues singer, aka Steve Goldfarb, in the guise of a pink slug…

Four states of matter can be seen in everyday life: solid, liquid, gas, and – somewhat more exotically – plasma. As a tightly bound combination of oxygen and hydrogen atoms, a water molecule is nothing out of the ordinary. Liquid water, steam or ice are still just water. Yet, it is intriguing to see how the very same building blocks of matter are capable of producing such broadly distinct states.

Ever since Francis Crick and James Watson brought Physics and Biology together in 1953 to unveil the molecular structure of DNA, the boundary between the two disciplines has continued to become increasingly blurred. In this genomic new era, ever more principles from Physics are being applied to living systems in an attempt to understand complexity at all levels. Although sometimes the best solution to a Physics problem lies in the macroscopic world of Biology…
What happened at time T = 0? is still anybody’s guess. At least, earlier observations of Planck’s radiation had suggested the first generation of stars were bursting into life by about 420 million years after the Big Bang. However, scientists from Europe’s Planck satellite mission now say the first stars lit up the Universe later than was previously thought…
Our planet has existed for 4.5 billion years, and it has been a busy lifetime. From amazing leaps and bounds forward into evolution to devastating asteroid impacts and other episodic extinctions, here are the biggest milestones in Earth’s history – the eventful journey that shaped our World today.
A friend of mine once casually asked me over a drink: “What is entropy?” Eeek! Interesting concept. But… How do you define entropy in a non-mathematical way? How can you sum up entropy in 30 seconds? In one mental image. In a single concept… In one word. A form of energy? A measure of disorder in the Universe? Randomness? All of the above? Tricky question. And then, I dropped my glass…

Ever since French physicist Louis de Broglie first described the wave-particle duality in 1926, scientists have struggled to come to terms with this strange particularity of our natural World when observed at the quantum level. Waves can be particles, and particles can be waves. But are entities waves AND particles all at the same time?

Scientists are currently exploring the concept of vacuum instability. What does this mean? Well, they believe there is a chance that… Billions of years from now, a new universe could open up into the present one and replace it. It all depends on some very precise numbers related to the Higgs boson particle that researchers are currently trying to pin down.
