Today two elements with names derived from places. In fact they are named after the same place. The University of California, Berkeley has been the home of many element discoveries (see Lawrencium and Seaborgium) including berkelium in 1949 and californium in 1950. I have represented berkelium with the most recognisable building at UC Berkeley: theContinue reading “Berkelium, Californium”

Curium is named for Marie and Pierre Curie, pioneers in the field of radioactivity (a word they coined). When we think of the Curies we tend to think of Nobel Prizes. It is easy to forget the hard grind of the bench chemistry that went into their achievements, and in particular the discovery of theContinue reading “Curium”

Despite having made a start on the f-block, I’m still pondering Group 3 and where to place scandium and yttrium. I like the suggestion Kit Chapman made to me, that I somehow represent the dilemma in my table. While I do want to settle on one way or the other for the table as aContinue reading “Mendelevium – the Periodic Table 152 years on”

I have almost completed the d-block and it’s come together nicely. The patterns take their inspiration from a wide time-span: from alchemy and classical mythology through to modern technology and applications. Many are pictorial; others are closer to the geometric patterns of traditional blackwork embroidery. As is befitting the transition elements, there are several referencesContinue reading “The Group 3 question”

Technetium caused me something of a headache. I struggled to think of a design, and found myself with a gap in the middle of my Periodic Table just as Mendeleev had over 150 years ago. For Mendeleev, the problem was never solved – technetium was not discovered until thirty years after his death – butContinue reading “Technetium”

America was not the only country involved in element discovery in the middle of the 20th Century. Russian scientists too were intent on adding to the Periodic Table and their contribution was initiated by Soviet physicist Georgy Flerov. Like Seaborg in America, Flerov had been involved in developing his country’s first atomic bomb. In fact,Continue reading “From Russia…”

Today two more elements named after scientists – two giants of 20th Century nuclear chemistry, Ernest Lawrence and Glenn Seaborg. The 1939 Nobel Prize in Physics was awarded to Lawrence for his invention of the cyclotron – a device that produces high-energy particles by accelerating them in a spiral path. The energy of these particlesContinue reading “Lawrencium and Seaborgium”

Given the hugely significant advances made by Ernest Rutherford and Niels Bohr in our understanding of the atom, they were obvious choices when it came to naming some of the more recently discovered elements. But the right to name these new elements was controversial and rooted in the Cold War. They remained without definitive namesContinue reading “Rutherford and Bohr”

Iridium is the first element I stitched, and though it got a mention back in the beginning it had little in the way of explanation. So, what better time to feature an element named after Iris, the Greek goddess of the rainbow, than in February – LGBTQ+ History month? And framing my pattern of miniContinue reading “All the colours”

Titanium was named for the Titans of Greek mythology, following the naming of uranium after Uranus, father of the Titans. It shares with the Titans the property of strength, and in combination with its low density and heat resistance, this makes it ideal for use in aircraft and spacecraft, often alloyed with aluminium, zirconium, nickelContinue reading “Titanium toilets”
