HENRY MOSELEY – A LOST TALENT

With the 100th anniversary of the First World War being marked later this year, Alan Mason sends us this interesting post about the war but particularly Henry Moseley, a now somewhat forgotten physicist. – Deskarati During the nineteenth century, wars were mostly fought by professionals (1). That is, the officer class had chosen the military as a life-long profession, and the lower ranks had volunteered to take up arms, often to escape rural or urban poverty. One of the unusual … Continue reading

A new element has been confirmed

Australian scientists have helped to create a brand spanking new element that will soon be added to the periodic table. The super-heavy element 117 (for now, it’s also temporarily being named ununseptium) was created in a lab by a team of international scientists. Its atoms match the heaviest atoms ever observed, which are 40 percent heavier than lead. In a press release, David Hinde from the Australian National University Nuclear Physics Department explains: “Making element 117 is at the absolute … Continue reading

Einsteinium – Es

Einsteinium is a synthetic element with the symbol Es and atomic number 99 in the periodic table. It is the seventh transuranic element, and an actinide. It was discovered as a component of the debris of the first hydrogen bomb explosion in 1952, and named after Albert Einstein. Its most common isotope einsteinium-253 (half life 20.47 days) is produced artificially from decay of californium-253 in a few dedicated high-power nuclear reactors with a total yield on the order of one milligram … Continue reading

Evidence for Ununpentium boosted

Scientists have presented new evidence for the existence of a previously unconfirmed element with atomic number 115. Temporarily named Ununpentium. The element is highly radioactive and exists for less than a second before decaying into lighter atoms. First discovered by Russian scientists in 2004, the super-heavy element has yet to be verified by the governing body of chemistry and physics. The new evidence is published in journal Physical Review Letters. “This was a very successful experiment and is one of the most … Continue reading

The Periodic Table of Middle-Earth

Click for larger view The Periodic Table of Middle-Earth was put together by Emil Johansson — a devoted Tolkien fan and an aspiring chemical engineer. Which this awesome chart makes blazingly obvious. As you can see, Johansson has replaced the standard chemical elements with characters from Lord of the Rings and The Hobbit. Each character is organized according to race (including Gothmog, who belongs to no known race) and is given a unique symbol and number. Johansson has even added … Continue reading
