Already this article is beginning to sound like one of those sempiternal quizzes you so often get on social media… but it actually shows how science reality connects. Are you having a scientific identity crisis?
This blog is so cool. It’s spontaneous! It’s electric!! But not as cool as it has been at these cutting-edge laboratories on the outskirts of Europe. Scientists there are dealing with an entirely new type of solid matter – ‘spontelectrics’.
In the run-up to the 2015 physics Nobel prize, which was awarded on Tuesday 6 October, Physics World looked at how Nobel-prize-winning physicists have been moving around the globe over the past century.
Mars is not the dry, arid planet we once thought it was. Under certain circumstances, liquid water has been found. NASA’s announcement has the potential of turning some Red Planet theories on their heads…
Let’s talk about size… 😉 How big are the objects floating in our Universe and how big can they get? Starting with a “big” object, our very own Moon… Embark on a tour of space… A tour of our Universe…
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…
Taking a radically different experimental approach, EPFL scientists were able to take the first ever snapshot of light behaving simultaneously both as a wave AND as a stream of particles. You need light to take a photograph. But how do you take a photograph of light?
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…
It’s late o’clock at night. All alone in the night? Enjoy this amazing time footage flyover of the Earth from the International Space Station. Absolutely uplifting… Positively enthralling…
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…
Right on cue, day turned into a sudden eerie twilight as a great swathe of the Earth’s surface quickly plunged into transient darkness. The magic number is 400. For many observers, weather conditions were far from ideal. Clouds obscured the much awaited spectacle of the 2015 eclipse. Thankfully, alternatives were available to astronomers keen not to miss the big event…
On 20th March 2015, the Moon will pass in front of the Sun and exactly block out most of its light. It will be the first total solar eclipse of the 21st century that is visible from the northernmost regions of Europe…
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.
This mesmerising image of the Northern Lights over Scotland was captured by Baltimore-born NASA astronaut Terry Virts, a member of Expedition 42 from the International Space Station earlier this week, as it drifted over Europe.
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…
At the beginning of the 20th century, the discovery of the radiometric “clock” revolutionised our understanding of the Earth’s deep history, confirming what geologists had been claiming for decades. Nevertheless, newer and more accurate dating methods posed further problems in themselves. After all, how do we know our Earth is 4.5 billion years old, and not a mere few thousands of years as suggested by the Bible?
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…
… is pretty much the bemused reaction you’ll get if you allow yourself to answer casual questions about science over a drink with a non-physicist. AB-SO-LUTE disbelief. Your fault! Shouldn’t have gone there… Pretend you didn’t hear the question… Especially if the answer is ion propulsion!
