The top one was done using armatures, which act like a chain of bones, in this case, 2 bones. The base of the chain is parented to the smaller gear so it follows it as it rotates. the other end of the chain is parented to an "empty" (essentially an invisible placeholder for an object). and that...

While a postulate is not a fact, it we can make predictions as what would happen if it were true. This, in turn allows us to devise real life experiment to test whether these predictions hold, and whether or not the postulate is valid. To date, all real life observations align with this...

A problem that arises when is comes to languages that are not native to you is that, not only do they have sounds that can be hard to properly form, they are sometimes even hard for your ear to distinguish, so you even hear it as the nearest equivalent in your language.

Yes, done with Blender.

Two methods I came up with from tracing out figure 8s. The first produces a somewhat uneven one as is, but you can slightly adjust the shape by fiddling with the lengths of the Arms at bit, and might get something better. The second method produces a more symmetrical path. It's overall...

We had my daughter and her partner over for dinner last night and had the TV tuned to a channel that was playing Christmas music on in the background. This is one of the songs they played.

The basic idea for the SOL in a vacuum is that it is invariant. Its speed relative to you as measured by you is always the same. So in the case of Doppler shift, this results in a different equation than one for sound. For sound, you use the form of (Vm±Vr)/(Vm±Vs), where Vm is the speed...

TIL that there are things even in your own "backyard" that you can be unaware of. For example, the local Portland International Airport has "support llamas" for stressed travelers during the Holiday season.

It's exceptionally high tides for the region. The contributing factors are 1. The Moon being near its perigee during a full or new Moon. 2.The Earth being near its perihelion. (So, this time of year is when they are going to occur.) 3. The alignment of the Moon's orbital inclination. Since...

Unfortunately, a over a month ago, at least two people who failed to take the King tide warnings seriously were caught by sneaker waves, and swept out into the ocean. You need to be aware at all times at the beach, but even more so during King tides.

As of late, we have been experiencing a good number of exceptionally high or 'King' tides. For example, this image is from video taken just recently at Cannon Beach, OR. My wife and I visit there often, and this particular ramp is an beach access we'll generally use. For comparison, this is a...

The store where we do the majority of our shopping does a "get a free turkey is you speed $125" deal in the week before Thanksgiving. It not too hard to spend that much when you are getting everything for the dinner. A few years ago it used to be $50 dollars, and I'd split the spending up over...

This reminds me of an episode of "Dharma and Greg". The main characters were discussing whose parents they would spend the holidays with. One of them responded, That's easy, we spend one with your family and the other with mine. That's the reason we even have two holidays where we eat the same...

As I might not have time tomorrow, this is for those who do celebrate it.
