“Modified gravity” could rule out both dark matter and Planet Nine

Our solar system officially houses eight planets, but some scientists say there could be a ninth. And that’s not just Pluto aficionados – evidence suggests a huge undiscovered world lurks on the dark fringes out there. Now, a new study has found the ou… Continue reading “Modified gravity” could rule out both dark matter and Planet Nine

Puzzling astronomical observations support alternative theory of gravity

Astrophysicists have observed some puzzling behavior in star clusters that seem to defy our current understanding of gravity at cosmic scales. Intriguingly, the observations fit with an alternative theory of gravity that could negate the need for dark … Continue reading Puzzling astronomical observations support alternative theory of gravity

Isaac Newton’s hand-written revisions to Principia fetch $2.35 million

Written in Latin and covering one and a half pages of 220 x 189-mm paper, the heavily-corrected draft is dated from May to July 1694 and features a total of 39 lines in Newton’s hand

One of the most valuable scientific documents in history changed hands this week, when an autographed Isaac Newton manuscript of revisions to three sections of the first edition of the Philosophiae Naturalis Principia Mathematica sold at Christie’s in London for £1,702,500 (about US$2,350,000).

Simulated Newton’s Cradle Makes A Flashy Desk Toy

Newton’s Cradle was once upon a time, a popular desk toy in offices around the world. For [TecnoProfesor], however, it wasn’t quite flashy enough. Instead, they built a simulated version with flashing LEDs. As you do.

Rather than relying on the basic principles of the cradle to make it work, …read more

Understanding Math Rather Than Merely Learning It

There’s a line from the original Star Trek where Khan says, “Improve a mechanical device and you may double productivity, but improve man and you gain a thousandfold.” Joan Horvath and Rich Cameron have the same idea about improving education, particularly autodidacticism or self-learning. They share what they’ve learned about acquiring an intuitive understanding of difficult math at the Hackaday Superconference and you can watch the newly published video below.

The start of this was the pair’s collaboration on a book about 3D printing science projects. Joan has a traditional education from MIT and Rich is a self-taught guy. This …read more
