It is, indeed, important to notice that my argument so far supposes no evil intentions on the part of the Humanitarian and considers only what is involved in the logic of his position. My contention is that good men (not bad men) consistently acting upon that position would act as cruelly and unjustly as the

Although the controversy over President Trump calling the current pandemic the Chinese Virus is the reason this post exists, I hope to use it to make some universal points. A friend of mine retweeted this: Hi. Yes, it originated in China, but the technical term is Covid-19 Your mom originated from the back of a

Robust learning requires humility and the ability to accept ambiguity… You see, one thing is, I can live with doubt and uncertainty and not knowing. I think it’s much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty

Earlier today, I ran into an interesting article, “The Ultimate Mystery? –‘Consciousness May Exist in the Absence of Matter’ (2019 Most Popular).” It, in part, discussed Andrei Linde‘s paper, “Universe, Life, Consciousness.” I’ll admit the majority of Linde’s piece was basically over my head, but it was a great read on the way to […]

“When am I ever going to use this?” has been asked about various parts of math by students through history. Come on. Admit it. You asked it before, didn’t you? 🙂 Ever used decibels? Then, my friend, you have used logarithms! From ”Understanding Decibels” on The SWLing Post: dB = 10 log10 (P2/P1) Okay, you

So, yesterday…yes, Christmas…I proved (or perhaps, better said “derived”) the Quadratic Formula. The fun didn’t stop there. 🙂 My oldest son (visiting for the holiday), seemed to enjoy what I was doing…so I figured I’d blow his mind with how polar equations act in graphs, first showing him a simple one. After a bit discussing

Woo hoo! It’s rough. It’s clearly done by a newbie. But we have produced our first “how to” tutorial video. Ever wondered how to solve the side-side-angle ambiguous case with a triangle? Haven’t we all?! Well, here is how to do it… See, I told you it was rough. 🙂 In many ways, this was

I debated which of my blogs to post this on…but settled here. Although I love what I do for work, “work/life” balance is important, and part of “life” should be exercising.

Today it is in the 70s. Tomorrow, the high is supposed to be 29. I’m not stupid. Well, not mostly, so I climbed on my bicycle today. 🙂 I figured it also would be a good chance to check out my new GoPro HERO8 Black, so I turned on Time Warp in auto mode. What

My GoPro HERO8 Black arrived earlier this week, but work, life, and school meant I didn’t really get to do more than just set it up prior to today. I had intended to take it on 12 mile round-trip bicycle ride (my usual trek to Byers General Store for a meatball sub), but it was

One of the greatest things about a GoPro is it can make a boring life interesting. 🙂 These are pictures taken during a water break on a bicycle ride to Byers General Store. And here’s a GoPro HERO7 Black Time Warp video at 15x: See?! Even my life is interesting at high speed! 🙂

What a beautiful fall day! Which means it was a great time to bring the RC car, with a GoPro on top, to the Strasburg Community Park. Key times for crashes: 1:55 (basketball court) 7:49 (baseball field #1) 9:06 (baseball field #2) P.S. The slow-motion isn’t near as smooth as I wish. I thought I

One of the problems I have doing math homework is wanting to take shortcuts (get ‘er done). I suspect, however, that it doesn’t save time in the end. Then, of course there are cases that prove that being meticulous is essential: “Spain builds submarine 70 tons too heavy after putting a decimal in the wrong

I started up college about 4 weeks ago, and in one discussion, a fellow student posited a 90° leftward phase shift to convert a cosine function to a sine one.  It made sense, but I told him that without proving it, our professor might come up with an exception. Well, yesterday on the way to

It was a teacher workshop day, so we quickly snuck over to the zoo for a quick visit. Augie got a bunch ‘o Pokemon in Pokemon Go along with hanging out with a friend.  It was a beautiful day, and although the GoPro isn’t zoomed in, you’ll still see some neat views (close and distant).

I just returned from another bicycle ride (and a yummy Byers General Store meatball sub midway). As I was cleaning up the remains of my lunch, I received a storm warning for Strasburg. Now, the adult thing to do would have been to wait it out. Instead I unpacked the GoPro, climbed on my bicycle,

I love riding my bicycle…and I love our four dogs. Speaking of love, our largest dog Chewie (65 pounds) loves going out and about whether for a walk or a ride in the car. Thanks to Amazon, Discount Ramps, and Lucky Dog (who actually makes the trailer), Chewie now loves joining dad on his rides. 🙂
