You'll recall that I wrote something about the American Cancer Society and fundraising a few weeks ago (here). That was a response to something Greta Christina wrote, and now, Greta has updated us on the situation and has this post that you must read: Has the American Cancer Society Been Caught…

Freethought Blogs is growing at an insanely fast rate. Glorious, says I! However, a lot of you may not be aware of all the authors on FtB. Even if you are, you may not know who their celebrity crushes are or what they think of Kim Kardashian's marriage. In an effort to acquaint everybody with…
You've heard about "ClimateGate." ClimateGate was a very successful but illegal campaign by anti-science to discredit climate science and climate scientists. Rest assured, the climate science is fine and the climate scientists are just trying to do their jobs, and doing quite well at that.…

The McGregor Museum is a complex building with several wings surrounding an inner court yard, a multi-layered roof, balconies everywhere, and numerous trees in the court yard close in to the building. So, a cat can spend the heat of the day in the shaded crown of a tree, and the cool of the…
Finally, without any further interruption ...
One morning I was up a bit earlier than usual, and I was in the bathroom shaving. It was an hour or so before sunup. The lighting in the bathroom was poor, but there was a security spotlight outside the window, as I recall, so I had opened the…
Since we are talking about geology, I do not want to give up the opportunity to bring up one of the coolest stories of geology ever, given the present day discussion of science and religion. You will be asking for a source for this story. Look it up in Wikipedia, where all knowledge resides, and…
One of the main reasons we were staying in Kimberley at all was to assist the museum staff with a particular, and rather singular, survey and excavation. The location and circumstances of this field project were quite remarkable.
This was on the location of an historic hunting reserve, where…
I wrote earlier about the graves that were dug daily to receive the dead. In truth, the details of this procedure are still being worked out by archaeologists at the McGregor Museum in Kimberley, but when we were there on this particular trip, part of the grave yard to which I refer had been just…
Well, we were living with this ghost who would walk up and down the hall in the middle of the night, invisibly leaving behind only the sound of its footsteps. But before I tell you how this all came out, I want to tell you a related side story.
As I had mentioned, I had the "hallway extension"…
So there we were in the Haunted Guest Quarters of the Old Infirmary, and I had already heard the ghost once. In the morning, my colleague and BFF Lynne who was staying with us for a couple of days noted that she had heard the mysterious footsteps as well....
"Greg, one, maybe both, of your…

What they say we get:
What we actually get:
1) 35% of every viewable surface of everything is an ad. Including the sky and the moon.
2) The technology pauses for several seconds every now and then because, well, it never works like on the ad.
3) A new EULA pops up several times a day asking you to…
The radiation at the Fukushima plants has gone up, rather than down, since June. This may be because contaminated water has become more concentrated due to evaporation. The release of radiation from the plant into the air continues, although a covering over Reactor 1 is almost completed. The…
More and more, nations are waging attacks with cyber weapons -- silent strikes on another country's computer systems that leave behind no trace. (Think of the Stuxnet worm.) At TEDxParis, Guy-Philippe Goldstein shows how cyberattacks can leap between the digital and physical worlds to prompt armed…
