5 GREAT LEGO CREATORS

Read Full Article: http://buff.ly/1rCwSLB

When most of us think of Lego, we remember a childhood spent sat on the living room floor creating multicoloured and structurally unsound homesteads. We remember spaceships and castles and cottages and sculpted gardens, and we enjoy the happy breath of nostalgia before continuing with our block-free adult lives.

Wow!!
We got so lucky last night! We spent our first 4th July as Las Vegas residents being treated to hundreds of firework displays around the valley just as a big thunder storm rolled in around the mountains surrounding the Las Vegas area. By the time the main show started around Caesars Palace and the Stratosphere, the lightning was getting pretty intense. Eventually, the rain passed through just before the finale. 

Luckily I was able to capture a few exposures that showed some of the craziness around us. The photo below is 5 shots from approximately 1 minute of the show. You can see a bigger version on my +SmugMug - http://www.tony.photography/New-releases/i-bqkVXjW/A

New Record For a Trapped Magnetic Field in a Superconductor

My last post was about the record for blackness, this one is about the breaking the record for a trapped magnetic field in a superconductor.  Seems to be a week for Materials Science breakthroughs.

Remember that a superconductor:
Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.  
http://en.wikipedia.org/wiki/Superconductivity

First discovered in 1911, superconductors are a class of materials including mercury and lead which, when cooled down to temperatures near absolute zero (–273 °C), can conduct electricity with zero resistance. Today, these materials are used to build the powerful electromagnets that go inside MRI machines, maglev trains and magnetic confinement nuclear reactors (tokamaks). In the future, they could be used to increase the efficiency of the power grid by carrying large amounts of electricity with very little loss.  ⓐ

In the late 1980s, scientists discovered a new class of materials that displayed superconductive properties at temperatures of up to 130 K – well above absolute zero. These so-called high temperature superconductors (HTS) are very attractive for real-world applications because they can be cooled with liquid nitrogen rather than liquid helium, making them much easier and cheaper to operate.  ⓐ

A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china.   ⓑ

The Cambridge researchers managed to ‘trap’ a magnetic field with a strength of 17.6 Tesla - roughly 100 times stronger than the field generated by a typical fridge magnet - in a high temperature gadolinium barium copper oxide (GdBCO) superconductor, beating the previous record by 0.4 Tesla. The results are published today in the journal Superconductor Science and Technology.  ⓑ  

The current carried by a superconductor also generates a magnetic field, and the more field strength that can be contained within the superconductor, the more current it can carry. State of the art, practical superconductors can carry currents that are typically 100 times greater than copper, which gives them considerable performance advantages over conventional conductors and permanent magnets.  ⓑ

The new record was achieved using 25 mm [≈ 1 inch] diameter samples of GdBCO high temperature superconductor fabricated in the form of a large, single grain using an established melt processing method and reinforced using a relatively simple technique. The previous record of 17.24 Tesla, set in 2003 by a team led by Professor Masato Murakami from the Shibaura Institute of Technology in Japan, used a highly specialised type of superconductor of a similar, but subtly different, composition and structure.  ⓑ

“The fact that this record has stood for so long shows just how demanding this field really is,” said Professor David Cardwell of Cambridge’s Department of Engineering, who led the research, in collaboration with Boeing and the National High Field Magnet Laboratory at the Florida State University. “There are real potential gains to be had with even small increases in field.”  ⓑ

While they are high quality superconductors with outstanding potential for practical applications, the cuprates can be as brittle as dried pasta when fabricated in the form of sintered ceramics, so trying to contain a strong magnetic field within bulk forms of the cuprates tends to cause them to explode.  ⓑ

In order to hold in, or trap, the magnetic field, the researchers had to modify both the microstructure of GdBCO to increase its current carrying and thermal performance, and reinforce it with a stainless steel ring, which was used to ‘shrink-wrap’ the single grain samples. “This was an important step in achieving this result,” said Dr John Durrell who led the experiment in Florida  ⓑ

“This work could herald the arrival of superconductors in real-world applications,” said Professor Cardwell. “In order to see bulk superconductors applied for everyday use, we need large grains of superconducting material with the required properties that can be manufactured by relatively standard processes.”  ⓑ

The story behind Stories!

If you love our recently announced Stories here on Google+ as much as we do, then you have to check out the truly wonderful story that +The Atlantic wrote on how Googlers +Joseph Smarr, +Brett Lider, +Clement Ng, and the entire Boswell team came together to help us share our stories in novel and memorable ways.

How 'bout that story?! ;)
