Creation of Stickney crater on Phobos
“This animation shows one scenario for how the massive crater Stickney could have formed, with a 200-meter object impacting at 8 kps into the 20-km-wide moon. The colored material is moving fast enough to evacuate the forming crater, and the red is moving quickly enough to entirely escape Phobos.“

Johnson specialized in nuclear mathematics, first working at Lawrence Livermore Laboratory and later Oak Ridge National Laboratory, where she worked on the Manhattan Project and later went on to a career developing scientific software for the Atomic Energy Commission.

IUPAC, Joint Institute for Nuclear Research, Lawrence Livermore National Laboratory: Name new element 117 Octarine, in honour of Terry Pratchett's Discworld
This petition is to name element 117, recently confirmed by the International Union of Applied Chemistry, as 'Octarine', with the proposed symbol Oc (pronounced 'ook'), in honour of the late Terry Pratchett and his Discworld series of books. The Discworld series has sold more than 70 million books worldwide, in 37 different languages. Terry Pratchett died in 2015 and his final book, The Shepherd's Crown, was published in the same year. He was well-known as a lover of science and, with two well-known science writers, co-wrote a series of four books called The Science of the Discworld, which took a sideways look at 'roundworld' (Earth) science. Octarine, in the Discworld books, is known as 'the colour of magic', which forms the title of Pratchett's first ever Discworld book. According to Disc mythology, octarine is visible only to wizards and cats, and is generally described as a sort of greenish-yellow purple colour, which seems perfect for what will probably be the final halogen in the periodic table. Octarine is also a particularly pleasing choice because, not only would it honour a world-famous and much-loved author, but it also has an 'ine' ending, consistent with the other elements in period 17. Octarine is being counted as 'a mythological concept' under IUPAC rules, which state that elements must be named after "a mythological concept or character; a mineral, or similar substance; a place or geographical region; a property of the element; or a scientist". The Discworld stories are certainly stories about gods and heroes, and 70 million books surely count for something.

Like the idea? Go sign the petition. I did.

Via boingboing – There’s a petition to name one of the newest elements in the periodic table “octarine,” after the color of magic in Terry Pratchett’s books:

A new Change.org petition to the Joint Institute for Nuclear Research at Lawrence Livermore National Laboratory (which has naming rights for element 117) asks them to name the new element in Terry Pratchett’s honour, as a remembrance of his early death in 2015.

The petition asks that the new element be dubbed “Octarine” (the imaginary colour of magic from the novel of the same name), abbreviated Oc (pronounced “ook” in honour of Unseen University's librarian).

The fact that you’d pronounce it “ook” is just … chocolate on the frozen banana. I SECOND THIS MOTION!!

Inside an underground nuclear explosion created cavity, 1961.

Lawrence Livermore National Laboratory’s Project Gnome, the first nuclear Plowshare experiment, was designed to explore the feasibility of using a deeply buried explosion in a dry salt bed for energy recovery and scientific nuclear experiments. The 3.1-kiloton device was detonated at a depth of 360 meters near Carlsbad, New Mexico. A researcher explores the created cavity, 23 meters high with a diameter of 49 meters.

Sequoia Throws Petaflops at Fusion Simulation

by Txchnologist Staff

One of the world’s fastest supercomputers has performed a record number of simulations to help physicists in their quest to produce fusion energy.

Lawrence Livermore National Laboratory researchers set all of their Sequoia supercomputer’s 1,572,864 processors (known as cores) on a single problem: modeling the motion of charged particles after a powerful laser beam strikes a dense cloud of ionized gas, called plasma. Using all of its cores, Sequoia can process 16.3 quadrillion calculations per second.

The machine is letting the team follow the simultaneous evolution of tens of billions to trillions of individual particles and the electromagnetic interactions between them. Such simulations are used extensively in plasma physics.

Scientists are developing 3-D printed helmets to prevent concussions

A group of researchers at the Lawrence Livermore National Laboratory are currently engaged in an 18-month study in collaboration with Autodesk Research, part of a 3-D printing software company, to design the helmet of the future. The group is investigating whether 3-D printed microstructures within helmet design can absorb more of the momentum of a collision than current helmet technology. To design the structure of the helmet, they’re starting with one question.
