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”

Lawrencium and Seaborgium

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”

I find the spiral form fascinating, and love how all the women are wearing bobby socks! It was actuallyContinue reading “Festival of Britain Periodic Table”
