Holy Thursday

Holy Thursday

Is this a holy thing to see In a rich and fruitful land, Babes reduced to misery, Fed with cold and usurous hand?

Is that trembling cry a song? Can it be a song of joy? And so many children poor? It is a land of poverty!

And their sun does never shine,And their fields are bleak and bare, And their ways are filled with thorns: It is eternal winter there.

For where’er the sun does shine, And where’er the rain does fall, Babes should never hunger there, Nor poverty the mind appall.

Real life Star Wars.

Laser Towards Milky Ways Center.

The color of the laser is precisely tuned to energize a layer of sodium atoms found in one of the upper layers of the atmosphere — one can recognize the familiar color of sodium street lamps in the color of the laser.

This layer of sodium atoms is thought to be a leftover from meteorites entering the Earth’s atmosphere. When excited by the light from the laser, the atoms start glowing, forming a small bright spot that can be used as an artificial reference star for the adaptive optics. Using this technique, astronomers can obtain sharper observations. For example, when looking towards the center of our Milky Way, researchers can better monitor the galactic core, where a central super massive black hole, surrounded by closely orbiting stars, is swallowing gas and dust.

Dogfooding

After two happy years as a WordPress self-hosted install, I’m moving our 8th grade science class site/home/hub, GriffinScience, to Blogger:

GriffinScience: “Because we’ll be using Blogger as a main platform of interaction with the 8th graders next year due to our school Google accounts making that a no-brainer, I’ve gone ahead and moved GriffinScience from a self-hosted WordPress install to Blogger.”

I don’t think the students will mind or notice much, and it does make a good deal of sense to eat my own dog food if I’m going to encourage students to make use of our school’s Google Apps accounts and use Blogger (or Google Sites) as their digital portfolio’s home (of course I don’t mind if they want to venture out into WordPress or Tumblr or Posterous land as well).

For some reason, this makes me sad in a “but I’m a real geek!” way. It’s not that Blogger isn’t a proper blogging engine or geeky enough site… but I’ve always encouraged folks to dive into code and make their own templates or sidebars. Those are possible in Blogger, but it’s a little too graphical and “easy” in my mind. I need to get over myself, clearly.

Nevertheless, here’s to another few good years of GriffinScience.
