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.

Many users, however, will have to add more memory if they want to run Mac OS X: It requires a minimum of 128 MB of RAM, which is more than Apple included in most of its consumer models until recently. The operating system runs even better with twice as much memory. (Fortunately, RAM is at record low prices, with many vendors now offering 256-MB modules for $50 or less.)

Ah, the good ole days…
