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

Happy New Year to those who have been kind enough to read or share my posts, and to everyone involved in adding to my knowledge and life in 2019. May 2020 be your best year ever and… #LetsLearnTogether.

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

Reading a bit about the history of algebra in  The Joy of x: A Guided Tour of Math, from One to Infinity, I was inspired to prove the quadratic formula I was originally taught in high school (and had reiterated this past semester in two courses at Indiana University East). The Arabic Santa is a

I recently purchased the GAOMON PD2200 drawing monitor from Amazon to create math tutorial videos (and for live tutoring). I have no artistic abilities, but my wife…who has an art degree…hopefully will push it a bit harder than me. (Quick note: please read the update at the bottom of the post. The monitor is not

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. Where I live on the high plains east of Denver, I consider it relatively temperate. However, my favorite mode of staying in shape, bicycle

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

Great, informative video from Mic Bergsma on how to clean you GoPro camera and accessories.

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! 🙂

We added two new pages to our site today. The first is of some of our favorite GoPro-related Youtubers. For instance, Mic Bergsma is our most favorite: Additionally, we’ve created a page to help you decide whether you should purchase a GoPro HERO8 Black. It will have links to reviews and information, but now it

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

So, admit it, you’ve always wondered what a car feels like in a car wash. 🙂 Well, here is your chance to find out!  Last night, around sundown, I put my GoPro HERO6 Black in a waterproof case, hooked it to the front of The Orangutan (what we call our VW Tiguan), and gave The

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).

Punishing the Class I’m going to assume two things of everyone here. First, that during school you were (or are) perfect angels. Never the troublemakers. Always the innocent, well-behaved bystanders. Second, that you’ll relate to this experience… You are just there, doing what the teacher wants, as white as snow…but the other kids in class

No bicycle video today, but how about seeing how the awesome sub I eat whenever I ride to the Byers Country Store is made?!: Actually, what you see there is two subs being made (kind of three actually). This time my wife and son met me at the store and we had lunch together. So,

You can see a longer post on Strasburg Rocks!, but I figured I’d share the time lapse I recorded this morning with my oldest son. One of my favorite features of my GoPro HERO7 Black is its Time Warp.

I spent quite a bit of time on Amazon comparing prices, features, et cetera for GoPro compatible selfie sticks, and finally settled on this aluminum Smatree Telescoping Selfie Stick.

My oldest son is in down for a few days, so he an I beat the heat today by heading for a bicycle ride before the temperatures got into the 90s. Yes, he made dad feel old. (I used to “pull” him along on bicycle rides back in New Hampshire. No longer.) Either way, here’s

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,

From yesterday, here is a quick bicycle Time Warp video from our home in Strasburg to the Byers General Store: Byers General Store has awesome food! 🙂 (And great people too…) This is the second trip where I enjoyed a meatball sub as my halfway reward. Hot day. Hovering around 90 degrees the whole time.

We previously had the Inaugural Chewie Bicycle Cam, but this is the Inaugural Chewie Cam (no “Bicycle”) thanks to a GoPro dog harness we purchased from…of all places…Circuit City (on eBay).

A week+ ago, my body was tortured into better shape by camping six days with Bennett Boy Scout Troop 30, so I am trying to keep my exercise up so as not to lose it. On Monday I rode back-and-forth from the General Store in Byers…and today it was McDonald’s in Bennett. This is a

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. 🙂

Yesterday, our Lucky Dog bicycle pet bicycle trailer arrived, and although it was late by the time I got home and had dinner, I had to try it out.

As I continue to try out the features of my GoPro HERO7 Black, here is an example of a Time Lapse Video (.5 seconds between images and 30 FPS). It was a very calm night…with stationary clouds. If you are able to watch it at full resolution, it’ll be 4K: It’s worth viewing full screen
