“It’s Like a Choir”

This has no bearing on your life and won’t change how you think about your drive to work.

“It’s like a choir, with all these supermassive black hole pairs chiming in at different frequencies,” Chiara Mingarelli, a NANOGrav scientist who worked on the new findings, said in a press release.

However, this is a HUGE deal. And those of us who follow these things are FREAKING OUT. Science is amazing. Life is amazing. This Creation that we get to participate in briefly is AMAZING!

Scientists Find the Gravitational Wave Background: What It Means:

Well, here it is. And it really is the big one!

Scientists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) have officially made the first detections of the gravitational wave background.

They made the first detections of what? Fair question, especially if you haven’t, in fact, been extremely tuned in to physics and astronomy Twitter. So let’s back up…

“What’s next is everything,” she said in a press release. “This is just the beginning.”

Chalk Apocalypse

So, when Hagoromo announced that it was going out of business in 2014, it caused a rupture in the math community.”

I referred to it as a chalk apocalypse,” Conrad said. In a panic, mathematicians across America began stockpiling resources in preparation.”

I calculated how many boxes I would need to last 10 to 15 years and I bought that many boxes,” says Lieblich.Dave Bayer took things even further. “I single-handedly bought the rest of the Amazon supply in the middle of the night,” he said.

I was gifted with an old sliding blackboard in my 2nd year of teaching (and my first year of teaching Physical Science). I loved that board and was sad to leave it later in my career when I went to a new school.

There’s something special about chalk covered hands and the feel of writing on a blackboard to make a point about F=MA or the structure of an atom.

Now I want to go stock up on some Hagoromo and find a good blackboard for my children.
