Nature.com has a great article, How ‘magic angle’ graphene is stirring up physics (Misaligned stacks of the wonder material exhibit superconductivity and other curious properties).
AskAMathematician.com has a good answer to, Why was it so hard to take a picture of a black hole?
bbc.com has an interesting story about how and why Japan exploded a small bomb on an asteroid.
Popular Science put together their list of the 100 greatest innovations of 2018.
From their website: “The 2018 Engineering Gift Guide from Purdue University is filled with fun toys, games, books, and applications to engage girls and boys ages 3-18 in engineering thinking and design. Researchers looked for toys that would promote engineering practices ranging from coding and spatial reasoning to problem solving and critical thinking.”
Back in my day, aerospace engineering undergrad students had very little time to work in the wind tunnels at Texas A&M, but in the limited time I had I tried to look at what makes a knuckleball move erratically. Barton Smith at Utah State University did the same thing (presumably with much more wind tunnel time) looking at a baseball’s spin rate, spin axis, and orientation of the ball.
The most interesting story for me yesterday was that a mile-wide meteor hit Greenland, possibly as recent as 12,000 years ago, and created an impact crater 19.3 miles wide. The impact would have released 47,000 times the amount of energy that was released by the Little Boy nuclear bomb that was dropped on Hiroshima in 1945. The impact crater was hidden by a half-mile thick sheet of ice until recently. (The image shown comes from the article I linked to.)
I enjoyed this National Geographic article about the migrations of the first Americans.
Tim Logan of Texas A&M University has a nice little article on Why you can smell rain.
From eso.org: “Observations made with ESO’s Very Large Telescope have for the first time revealed the effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way. This long-sought result represents the climax of a 26-year-long observation campaign using ESO’s telescopes in Chile.”
