Fornax Chimiæ: May 2015
http://fornaxchimiae.blogspot.com/2015_05_01_archive.html
Sunday, May 10, 2015. Boy Genius Blocks Navy Wireless. Commander Albert C. Gleaves U.S.N. of the Torpedo Station in Newport, Rhode Island, had a problem. The government had installed a new wireless station for ship-to-shore communication but in 1906 they were experiencing interference from a nearby amateur radio operator. My sign was GR. GR GR GR, they said, if you dont stop operating that coil, you will find yourself in the jug shortly. I answered by sitting on the key. I was such a nice boy! Magazine&#...

Fornax Chimiæ: About Me
http://fornaxchimiae.blogspot.com/p/about-me.html
In the dome with the 12". I'm the Curator of the historic Ladd Observatory. The Observatory opened in 1891 and is part of the Department of Physics at the Brown University. There is a weather station on the roof that includes a lightning detector and an all sky camera. I setup the system for making the data from these sensors available on the web. Repairing an A/D channel on the pdp-12. Photo by Dave Fischer. We collect, restore, and preserve computers from as early as the 1960s. Our collection prima...

Fornax Chimiæ: August 2014
http://fornaxchimiae.blogspot.com/2014_08_01_archive.html
Sunday, August 10, 2014. As we saw in part 1. Of this series the typical measurements of sky brightness in Providence are between about 4.1 - 4.3 nelm (naked eye limiting magnitude) on clear nights. Here is a graph that shows a typical hazy summer night. The readings were taken on the night of July 1st into the morning of July 2nd of 2014 and are in the range that we commonly see. The dashed horizontal line is a somewhat arbitrary. Links to this post. Saturday, August 9, 2014. In my previous post. To jud...

Fornax Chimiæ: Sky Brightness 2
http://fornaxchimiae.blogspot.com/2014/08/sky-brightness-2.html
Saturday, August 9, 2014. In my previous post. Location: Ladd Observatory, 210 Doyle Avenue, Providence, RI 02906, USA. August 15, 2014 at 2:35 PM. In regard to that feature at 04:00 UTC, perhaps you could separate the data based on whether standard time or daylight savings time is in effect. Comparing the two graphs might show whether the feature is correlated with UTC (astronomical) or local time (human made). Subscribe to: Post Comments (Atom). View my complete profile.

Fornax Chimiæ: Trilobite Detritus
http://fornaxchimiae.blogspot.com/2015/03/trilobite-detritus.html
Friday, March 27, 2015. The Craigleith area of Ontario is well known for its abundance of fossils. In 1992 I visited this locality on the southern shore of the Georgian Bay to search for them. There was a railway cut through the shale near Collingwood. The first slab of rock that I cracked open revealed a cluster of trilobite carapaces. They date to the late Ordovician which is about 445 million years ago. Closeup of trilobite tail pieces. Are extinct marine arthropods. The carapace. Location: Craigleith...

Fornax Chimiæ: As the Bubbl Bursts
http://fornaxchimiae.blogspot.com/2014/08/as-bubbl-bursts.html
Monday, August 4, 2014. As the Bubbl Bursts. The invention of magnetic bubble memory was once seen as a revolutionary computer development - the wave of the future. It is now a nearly forgotten technology. Many persons expect that the most dramatic changes in digital systems will result from magnetic-bubble chips that could well hold a million or more bits in the not-too-distant future. Along with charge-coupled devices, these memories show promise of replacing magnetic tape and disks. The Bubbl-Board &#...
