Bending Star Light - Thursday, March 27th 2014 21:02
This is another one of those entries that got started days ago, but wouldn't finish itself, so I had to step in and get it done as my energy and concentration allowed. At this...
The Weight of Light - Saturday, March 22nd 2014 21:47

The Narrow Gate - Tuesday, March 18th 2014 0:18

Who's on Second; What's on First - Thursday, March 6th 2014 21:42

Healing on the Sabbath - Wednesday, March 5th 2014 23:31
We had more snow again today! And the long-range forecast predicts some more next week. I'm sorry I'm stuck on the weather, but--then again--we're stuck with what we're...
A Fig Tree in a Vineyard - Tuesday, March 4th 2014 22:03
We've not given Luke his turn in several posts, so it's definitely time to return to the Bible passage. (I have the next entry on relativity laid out in my mind already, but...
Special Relativity and Clocks - Sunday, March 2nd 2014 18:40
How does relativity slow down clocks? I’ve phrased the question in a way that actually already embeds any number of misconceptions. However, judging by some Q&A sites...
The Speed of Light - Saturday, March 1st 2014 19:48
Just to get it out of the way, in case you’re interested, winter is still solidly ensconced here in Indiana. The forecast includes some temperatures at or below 0°F, and...
Babies, Ships, and the Ether - Monday, February 24th 2014 16:39
Student Bodies and Babies. Relativity is not a new idea. Nor is the idea that what we see is not necessarily what we get. Kenneth R. Atkins, the author of my undergraduate...
This and that--all important - Friday, February 21st 2014 22:14
The article that almost ate my life. So, I agreed a while back to write a chapter on Hegel for an upcoming anthology on modern philosophers and theology (edited by Ben Arbour...
Tumultuous Times - Tuesday, February 18th 2014 21:26
It wasn't quite a heat wave, but we actually had some thawing weather. It's going to take a while for all that snow to vanish, but at least we're heading in the right direction,...
Camels in the Ancient Near East - Sunday, February 16th 2014 16:20
I really hadn't intended to write about camels. But since the topic keeps coming up, I feel that I need to state my observations on this issue (or, really non-issue). The...
Einstein vs. Bohr, part 2 - Thursday, February 13th 2014 17:44
In the light of a rather unfortunate set of comments in Facebook, please let me reiterate what I said at the beginning of this series, which I'm assembling at a single site as...
Einstein vs. Bohr, part 1 - Wednesday, February 12th 2014 23:50
As the women's downhill ski event is on TV at the moment, a few thoughts on these Winter Olympics.June and I have watched a lot of the events so far. We don't have many places...
This little light of mine - Friday, February 7th 2014 22:12
Your industrious bloggist has been under the weather for a couple of days, just enough to keep from moving on from quantum mechanics to relativity. How did I ever get myself...
ISCA Call for Papers! - Wednesday, February 5th 2014 11:57
This post does not fall into either of the two series that I'm alternating at the moment. I've been remiss in promoting this year's ISCA program. I guess I got out of the rhythm...
Concerning Worrying - Sunday, February 2nd 2014 16:35
It's Groundhog Day. I don't know what the weather is like in Pennsylvania today, but if any local ground hog lacked the sense to remain in its hole and stuck its nose out, it...
Excluded Middle - Saturday, February 1st 2014 23:46
Before getting into the subject matter of tonight's entry, a couple of things. First, thanks to the anonymous encourager who emptied his or her piggy bank and mailed the...
The Rich Fool - Tuesday, January 28th 2014 22:43

The Philosophy of Physicist X - Monday, January 27th 2014 23:18

The Pressures of Persecution - Friday, January 24th 2014 21:50
I made a quick trip to Cox's, the local grocery store, late this afternoon (Friday) and found myself there with about half the population of Smalltown, USA (Alexandria,...
