Visitor in our backyard
By the time I could run and grab the camera, it was out of the backyard into the woods.

This is how photocopies are made… It is a 3 step process:
1. light reflected from the white parts of the original is focused onto a charged printing “drum,” where it locally dissipates charge;
2. positively charged toner particles are attracted to the remaining charged areas that were dark in the original;
3. paper is run over the drum to pick up the toner to create an image of the original.

Global warming This article appreared

Global warming
This article appreared in The New York Times about 2 weeks ago. It talks about evidence of changes in the world due to global warming and what could happen if the warming trend continues. It is an interesting read. Here are a few lines from it…
Skeptics of global warming should come to this Eskimo village on the Arctic Ocean, roughly 250 miles north of the Arctic Circle. It’s hard to be complacent about climate change when you’re in an area that normally is home to animals like polar bears and wolverines, but is now attracting robins. A robin even built its nest in town this year (there is no word in the local Inupiat Eskimo language for robins).
…
The Okpilak River valley was historically too cold and dry for willows, and in the Inupiat language “Okpilak” means “river with no willows.” Yet a warmer, wetter climate means that now it’s crowded with willows.
…
Alaska has warmed by eight degrees, on average, in the winter, over the last three decades, according to meteorological records.
…
In the hamlet of Deadhorse, I ran into an Arctic native named Jackson Snyder, who said that winters were getting “a lot warmer; doesn’t get much below 50 below anymore.”
…
That may not seem so bad. But while there will be benefits to a warmer Alaska (a longer growing season, ice-free ports), climate change can also lead to crop failures, spread tropical diseases and turn Bangladesh into tidal pools. The pace of warming may be far too fast for animals, humans or ecosystems to adjust. My advice is that if you’re planning a dream home in New Orleans or on the Chesapeake, put it on stilts.
…
It predicted that in this century, the seas will rise 4 to 35 inches. Global warming is still an uncertain threat, but it may well become one of the major challenges of this century. Unless we act soon, we may find waves lapping the beaches of Ohio.
Thanks, Mayuresh.

Why do we hear a thunderclap?
The average temperature of lightning is 76000 F. In that split second when lightning appreas, the extreme temperature expands the air violently. This explosion of air creates the sound wave that we hear as a thunderclap.

If ‘Lord of the Rings’ is made in Hindi, they would not have to animate Gollum. Shah Rukh Khan is perfect to play that role. All the nervous twitches and shakiness match perfectly.

B-flat Black hole The numbers
September 11th, 2003
B-flat Black hole
The numbers in this article are just astounding… This supermassive blackhole is 250 million light years away. The frequency of the sound is 1 cycle per 9.5 million years. Whoooa!
After observing the Perseus galaxy cluster for 53 hours in August 2002, the Chandra X-ray Observatory revealed ripples in the hot gas that fills the cluster. These ripples appear to be sound waves that would register as a B flat if we could hear the deep tone. The team that discovered the waves determined their frequency by calculating the speed of sound in that environment and measuring the distance between wave crests. The frequency is about one cycle (or wave) per 9.5 million years or so; corresponding to a B-flat note about 57 octaves below “middle C” on a piano.
