Researchers finally figure out how tire sounds are made

Apparently we didn’t know until now. I highlighted this story because of: (a) the cool illustration; and (b) science.

With supercomputers capable of beating our best chess and Jeopardy players, you’d think that being able to simulate the sounds a tire makes while rolling on a road was easy—but it’s not. In fact, Yokohama had to team up with the Japanese equivalent of NASA to finally recreate how air and sound behave around the company’s tires.

Working with the Japan Aerospace Exploration Agency’s Institute of Space and Astronautical Science, Yokohama’s researchers used a detailed 3D model of a tire to finally simulate how the sounds it produces are created. And it turns out those sounds are not only produced by all the air turbulence around a rolling tire, but also by the constant compression of air in front of the tire where it meets the road, and as it circulates around it.

SURPRISE! Common Core Third Grade Text Book Portrays Obama as God-Like Figure

Gee, who could have predicted this?

On the heels of a controversial children’s book about Barack Obama – which stated “white voters would never vote for a black president” and that “Barack’s former pastor” said “God would damn the United States for mistreating its black citizens” – comes a new lesson that casts America’s 44th president in a messianic light. Literally.

And – surprise – it’s Common Core-aligned.

The lesson plan and accompanying visual presentation were authored by Sherece Bennett, and is for sale on TeachersPayTeachers.com. It’s all based on a book titled, “Barack Obama: Son of Promise, Child of Hope,” by Nikki Grimes.

…In one passage, a young Obama sees beggars and wonders, “Will I ever be able to help people like these?”

“Hope hung deep inside of him,” the book adds.

Another excerpt from the book reads: “Before dawn each morning, Barry rose – his mother’s voice driving him from dream land. ‘Time for learning English grammar and the Golden Rule. Be honest, be kind, be fair,’ she taught him.”

The story continues: “One morning, he slipped on the name he’d been born with. The name of his father, Barack. For the first time in his life, he wore it proudly – like a coat of many colors…”

Grimes’ book and Bennett’s lesson plan are more fitting for an authoritarian regime in which children are taught to deify and praise their dear leader. One can almost envision teachers in Cuba, Venezuela and Iran using similar books and lessons.

Any resemblance to real persons, living or dead, is purely coincidental.

The Democrat Party is lost. And it’s high time to flush them out of government, at every level of government, next November.
