Kawah Putih Lake (x)
"The Kawah Putih site was opened to visitors in 1987. The lake is 2,430m (7970 ft) above sea level, so the local climate is often quite chilly (temperatures are frequently around 10 degrees celsius). This makes a brisk change from the humidity of the north Java plain and the capital city of Jakarta. Kawah Putih is a sizeable highly acid lake (pH 0.5-1.3) which changes colour from bluish to whitish green, or brown, depending on the concentration of sulfur and the temperature or the oxidation state. The sand and rocks surrounding the lake have been also leached into whitish colours through interaction with the acidic lake waters (with possible mineral precipitation as well)."
On 9th March 2008, historians have found what they believe is the first recording of a human voice. Predating Thomas Edison’s first phonograph recording of 1877. The “phonautograph”, created by etching soot-covered paper by Parisian inventor Edouard-Leon Scott de Martinville, was played by US scientists using a “virtual stylus” to read the lines. The recording was initially believed to be the voice of a woman or adolescent, but further research in 2009 suggested the playback speed had been too high and that it was actually the voice of Scott himself. This is the original recording.
