Salad Growing… in Space?Ever since the early days of human space travel, back in the 1960s, astronauts have run experiments involving plants in space. Over a million seeds of rocket (two kilograms of rocket seeds) are shortly due to take off from Florida, bound for the International Space Station, as part of British ESA astronaut Tim Peake’s six-month Principia mission.

#BlueDotExpedition 43 astronaut Samantha Cristoforetti snapped this photograph of herself wearing the Starfleet uniform from TV series “Star Trek: Voyager” aboard the International Space Station, and posted it on her Twitter account @AstroSamantha last month.
LOUD!!!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. Continue reading The Sound of Physics
Eye on the Energy Sources of the FutureGeothermal energy prospectors have long used gravity meters in their search for the right subsurface characteristics. But these have been point measurements. GOCE now provides this information across the World at a resolution never before achieved on that scale. Continue reading Geothermics and Gravity – The IRENA Global Atlas for Renewable Energy
Dark Matter“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... “And did it really kill the dinosaurs…?” Continue reading That Mysterious Missing Matter – Cocktail Party Physics
Two Guys Walk Into a Bar…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… Continue reading The Basics of the Higgs Boson Explained
Orbiting SpheresRight 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… Continue reading 400 – Anatomy of a Solar Eclipse
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… Continue reading Celestial Rendez-Vous – An Equinoctial Total Eclipse of the Sun
#BlueDotThis 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. Continue reading Northern Lights over Scotland
Who, What, Where?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… Continue reading Planck’s Time and the “Oldest Light” in the Cosmos
Cross-Referencing Geological TimeAt 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? Continue reading Testing Times – Methods of Dating the Geological Past
Earth is BornOur 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. Continue reading Earth Creation – The Story So Far…
“That’s Star Trek stuff!”… 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! Continue reading The Ion Propulsion System – What the… #!$@*!!
Multiple Sclerosis? Is that contagious?We all know about diabetes, heart disease and cancer. Well, as much as any of us can learn from watching the news whether on TV or on the Web. On average, the advice is loud and clear. You’re told to: eat healthily, exercise moderately. Additionally, don’t smoke, don’t take drugs and go easy on your alcohol consumption. Overall, it makes good sense. Your heart, your lungs and your liver play a major role in keeping you alive and well. That little, everybody realises. But how much do we really know when it comes to illnesses of the nervous system? And without a healthy nervous system, well… This article deals with Multiple Sclerosis. It is an attempt to fill a gap in my own general ignorance and to inform others about this cruel condition…
GOCE – Gravity Field and Steady-State Ocean Circulation ExplorerGOCE succumbed to gravity – the force it had been sent up into space to study. Ironically. When the xenon fuel for this engine was exhausted, the satellite fell back to Earth in November 2013. The first of ESA’s Living Planet Programme satellites, GOCE was intended to map the Earth’s gravity field in unprecedented detail... Continue reading GOCE and Gravity – Looking Down at the Oceans Up Above
Lift-Off!Florida has Cape Canaveral, and now it seems the UK city of Sheffield has a new space port dubbed “Cape Kebaberal”. The name was inspired by the favourite student food of Alex Baker and Chris Rose, who run the Sheffield-based company SentIntoSpace. Continue reading It’s All Go at “Cape Kebaberal” in Sheffield…
Van Gogh’s Starry NightWhen Classical Physics and Post-Impressionist artists meet, few results are as hauntingly beautiful or as enchanting as one of Vincent van Gogh’s most famous masterpieces. The Starry Night embodies the inner, subjective expression of van Gogh’s response to Nature. And the churning night sky he depicted tells of the artist’s very unique perception of the World around him… Continue reading A Starry Starry Night or The Unexpected Maths in a Van Gogh’s Masterpiece
Falling from Outer SpaceSince October 24, 2014, Alan Eustace holds the World Records for vertical speed reached during freefall with a peak velocity of 1,321 kilometres per hour (822 mph) and total freefall distance of 123,414 feet – lasting four minutes and 27 seconds. Continue reading Four Minutes and 27 Seconds of Freefall Fun – Two Years after Baumgarten, a New Record!

It seems quiet at first, and even dull. Not much happening… Dreich, as one might say! Sad. Grim. Bleak. Not much to do… Not much to see here… Just sheep… But wait!! Look closer! Is that Dolly in this field? Now, that’s interesting! Oh, Aye, we’re in Scotland! It changes EVERYTHING… Continue reading Scotland’s Quiet Revolutions – One Nation with Sovereign Achievements… and a Pure Dead Brilliant Future!
The Industry Term is ‘Fracturing’Hydraulic fracturing, more commonly referred to as “fracking” in the media, is the fracturing of rock by a pressurised liquid. Some hydraulic fractures form naturally – certain veins or dikes are examples. However, induced hydraulic fracturing or hydro-fracturing is also a long tried-and-tested mining technique that has been most controversial recently… But let’s not panic! Continue reading The Craic about “Fracking” – Technical Facts on Hydraulic Fracturing
Gravity-Defying LanscapesOver millions of years, weathering and erosion of sandstone have produced unique landforms, such as arches, alcoves, pedestals and pillars. Until now, the natural process remained a mystery. It was difficult to study, because of the huge time-scales involved in the erosion of natural slabs of sandstone. Gravity-induced stresses had been assumed not to play any role in landform preservation. Instead gravity was thought to increase the rates of weathering and natural erosion… Continue reading Eroded Earth: The Forge of Gravity
Scotland’s First Nano-SatelliteEarlier this month, UKube-1, a satellite built by Glasgow-based technology firm Clyde Space, successfully launched on a test flight from Baikonur, Kazakhstan. It is the first ever spacecraft to be fully assembled in Scotland. Continue reading Satellite of Love – It’s Up, Up and Away for Scotland’s UKube-1
