GOCE – Gravity Field and Steady-State Ocean Circulation Explorer
GOCE 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...
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.
When 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…
The United States have one. The Danish used to have one, and so did the Brits, but no longer. France remains the only country in Europe to have one. So, what exactly is the GEIPAN?
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?
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…
The human nervous system contains roughly 100 billion nerve cells. Worth pausing for an instant… and read it again. That’s right, 100 billions! To give an idea of the scale, the Milky Way, our own galaxy, contains roughly 100 billion stars. And although human beings are way smaller than galaxies, we begin to appreciate how each one of us is as complex, as mysterious, and as magnificent in its own right, as any large astronomical entity in the physical Universe.
Earlier 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.
What is the difference between heat and temperature? Heat is thermal energy. Temperature is a measurement of the average kinetic energy of the particles which compose the matter being tested. When heat flows into a material, one of two things happen: either the temperature of the material can rise, or there may be a change in its state (such as from ice to liquid, or liquid to vapour).
Helium is the second most abundant element in the Universe, after hydrogen. On Earth, helium is relatively rare, because it is one of the few elements that can escape gravity and leak away into space. Therefore, helium exists as a finite resource. But as our reserves of the precious element steadily decreases, helium is in increasing demand. In medicine, helium supports the fight against cancer…
They are found everywhere in Nature. From the leaf arrangement in plants, to the pattern of the petals of a flower, the bracts of a pine cone, or the scales of a pineapple. The Fibonacci numbers are applicable to the growth of every living thing: a single cell, a grain of wheat, a hive of bees, all of mankind. From sunflowers to sea shells, the same recurrent mathematical pattern can be observed in Nature, again, and again, and again…
Break a magnet into two pieces, and what do you obtain? What you get, unsurprisingly perhaps, are two new magnets – each one with two sides of opposite polarity. You don’t get a north half and a south half. Back to square one, it seems…
January 20, 2014. 500 million miles from Earth. 09:59:58… 09:59:59… 10:00:00 GMT. After spending two and a half years into deep-space hibernation, Rosetta awakes…
Commander Chris Hadfield ascended to international stardom when he released his cover version of David Bowie’s 1972 Song ‘Space Oddity’ from the International Space Station.
An Essential Molecule for the Sustainability of Life
Water. H2O. The chemical formula is simple. Two atoms of hydrogen H and one atom of oxygen O, held together by covalent bonds, are all it takes to make what is perhaps the most fundamental substance to life on Earth.
Just when you had high hopes of getting your hands on the latest gizmos and trendy gadgets in time for Christmas… and Boom! You’re being given a comet! Not just any comet. Comet ISON (C/2012 S1). It’s 4.6 billion years old! And it will pass within 40,000,000 miles of Earth.
Just nine months ago, a massive asteroid blew up above the city of Chelyabinsk in Russia. The explosion of the Chelyabinsk asteroid on Friday 15 February 2013 was thelargest explosion on Earth since the one that occurred over the Tunguska region of Siberia in 1908.
Back in May 2013, scientists announced that they had managed to capture a photo of an electron’s whizzing orbit within a hydrogen atom, using a unique new technology of ‘quantum’ microscopy. Ladies and gentlemen, let’s take a short trip into the infinitesimally small! Here is the first photograph of a hydrogen atom!
The Physics Nobel Prize was awarded on 8 October 2013 to Edinburgh University-based scientist Peter Higgs for the theoretical discovery of a mechanism crucial to our understanding of the origin of everything…
According to the current understanding of Physics, there is as yet no uniform field theory. No all-encompassing well-rounded theory that would enable all the known fundamental forces and elementary particles to fit neatly into one simple model, and to be expressed in terms of a single field.
Over 50,000 deaths each year in the UK are attributed to air pollution. Physicist, entrepreneur and father Mark Richards is concerned about the environment and in particular the air pollution that we expose our children to. He has developed a handy machine which can monitor air quality. He wants people to see how bad air pollution is, so that we all think more carefully about our lifestyles and travel methods.
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.
Glasgow Science Festival 2013 begins today with a busy schedule of events for all ages!! Highlights include “Science Sunday”, a free event taking place at the University of Glasgow, Hunter Halls on June 9th between the times of 10:00 and 16:00.
