Optomechanical coupling between a multilayer graphene mechanical resonator and a superconducting microwave
Devices made from resonating graphene “drums” could be used as microwave amplifiers and memory chips in quantum computers. So say researchers at the Kavli Institute of Nanoscience at the Delft University of Technology in the Netherlands, who are the first to demonstrate optomechanical coupling between a mechanical resonator and a superconducting microwave cavity.

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we’ve ever known.

Lyrics (written by LH):
The sun burns bright on the playground today, not a student to be seen.
A kingdom of education, and Mrs. Hagan is our queen (she’s our principal)
I hear their voices like they were here just yesterday…
We can’t keep them out, they’ll be here Monday.

Don’t let them in, my room’s not clean,
I need more time to plan with my team,
Ready or not, they must be taught…
Ready or not…

Here we go! Here we go!
Let’s teach that Common Core! (or not?)
Here we go! Here we go!
With assessments galore!
I’m prepared for all the germs they’re gonna share!
Bring the school year on…
You get a little bored at home anyway.

It’s funny how a summer can make them forget how to walk in the hall,
And even with 10 weeks off, they didn’t read at all! (seriously?!)
It’s time to see what they can do, to test their knowledge, and hope we can break through!
It’s the honeymoon, they all get along…but not for long…

Here we go! Here we go!
Here’s hoping their pants stay dry!
Here we go! Here we go!
You know you’ll make someone cry.
Here I stand with lessons planned!
Bring the school year on…

(interlude)

Bring on the data, rubrics, and coffee by the pound,
My head is spinning fast with acronyms swirling all around!
Let’s hope we teach them more than just what’s on the test,
We’ll love and teach them well, at least we’ll try our best!

Here we go! Here we go!
As we rise at the crack of dawn,
Here we go! Here we go!
Our sweet summer freedom is gone.
Here I stand, class rosters in my hand,
Bring the school year on…
Admit it, we all love this job anyway.
