Recycle Michael talks with Dieter Eckels of Cascadia Consulting Group on the absurd and fascinating topic of waste characterization; the process of sorting garbage to gather data to better understand it. Getting intimate with trash is important to understanding what it is we are wasting and recycling. This show talks about the brutal work passionate people do to work toward solutions to wasting.

Trash Talk Ep 09 - Dieter Eckels on the Character of Waste

For the first time, NASA released a sonification simultaneously with news results associated with two of its telescopes, the Imaging X-ray Polarimetry Explorer (IXPE) and the Chandra X-ray Observatory. The data cover the region near the supermassive black hole at the center of the Milky Way galaxy. The black hole, known as Sagittarius A*, is barely seen in the lower right-hand of the visual image that contains X-ray data from IXPE (red-orange) and Chandra (purple). In the sonification of these data, the cursor begins at Sagittarius A* and moves out as a growing circle toward the center of the image. As it encounters IXPE data, the volume of the notes changes according to the brightness of the X-rays. The brighter the Chandra data, the higher the musical pitch and vice versa. When the cursor travels over a large patch of X-rays both from Chandra and IXPE in the center of the image, a rushing sound is heard. This region is where scientists find a “light echo,” a high-energy relic left behind from an eruption from Sagittarius A* about 200 years ago.
