Hubble telescope uncovers black hole that shouldn’t exist

From NASA.gov: As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

The conundrum is that the disk shouldn't be there, based on current astronomical theories. However, the unexpected presence of a disk so close to a black hole offers a unique opportunity to test Albert Einstein's theories of relativity.

Can snakes see?

I’ve seen five rattlesnakes since I moved to Colorado, four dead and one that was quite upset with me. As I was walking yesterday I wondered, can snakes see? Here’s an answer from animals.howstuffworks.com.

LiveScience.com adds this information: “With the exception of a few species that have adapted to daytime hunting, most snakes do not see well. Generally they can see shapes but not details. Snakes called pit vipers can see well at night by an amazing trick. Their pits (one on each side of the head) sense heat (infrared light) like night vision goggles. These pits, not eyes, actually are thought to render images of prey in the snakes’ brains.”

Purdue University 2018 engineering gift guide

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.”
