Cold and black

For some odd reason instead of being asleep in the wee hours of the morning I was thinking about how we often label as opposites what are really lesser and greater quantities of the same thing. The best examples I could think of were temperature and light.

In temperature we refer to hotter and colder but the quality 'cold' really doesn't exist outside of ourselves. It's purely a subjective relationship. Heat is a measure of how much kinetic activity there is in something. It can vary quite a bit. From zero (absolute zero) activity to the top end in plasma where all normal characteristics of a substance are lost. What we refer to as 'cold' is just a range on that continium. Similarly black isn't a color. It's just the absense of light. Light can appear in colors depending on how it's being filtered. White is merely all the colors combined. But pure black only exists in the absense of any light.

I guess it's mostly semantics...

Fights over semantics have caused wars. I know people that will argue all day long over semantics. You are most correct in your position, however. There is no cold, only absence of heat. There is no black, only absence of light.

Sure thing,we're just talking about comfortable heat,as we talk of the amount of light necessary to our eyes to see arount us. No heat at all or no light at all: we never had.
in a crowded universe hard to reach point zero.

Nitroflex at home

Image
I mentioned a few days ago that I'd purchased off of Craig's List an exercise machine. A Nitroflex, to be more specific, for the grand sum of $75. The boxes you see to the left were bought by the seller as discontinued merchandise over a year ago and stored in his back yard storage shed. You might be able to see some of the bugs and such that had made their homes on these boxes. I left them out on my deck for a few days before opening them to allow the insects to leave gracefully or die in the sun. The picture to the left is the pieces from the box, unboxed, and up in one of my upstairs bedrooms. For the most part it wasn't difficult to move it around though two pieces were heavy and a number of them were kinda long and bulky to be wandering about the house with. Surprisingly, this kit didn't require any extra tools. There were two allen keys and one combo wrench included in the boxes and that was all it took to put it together. The whole thing only took about half an h

flea!

Yep, that's one of those damn blood suckers. Renee's revenge on my neglecting her feelings, no doubt. We guys just have it so tough! LOL This here is a picture of my ankle and while it's not very obvious, I guess, there's a bunch of flea bites on there. Itches a bit, dammit. The annoying part is that the damn fleas can't use my blood--fleas are mostly species specific and don't have the proper enzymes to make meals out of blood from other critters--so they're not getting anything out of biting me. It's just frustration and starvation driving their biting. Well, I guess the real annoying part is the bites themselves, but I wanted to seem a little sensitive there for a moment. But no more of that. Kill the fleas! While most of the bites are on my ankles and calves, there's an occasional bite up higher like these 4 on my thigh. They're kinda hard to see through the hair but I wasn't able to focus on the skin with all the hair in the way. Sorry.

ankles: the sequel

Image
I've heard rumors that one post about my sprained ankle wasn't enough so here's more pictures to satisfy a public hungry for swollen flesh... This was taken the morning after I sprained the ankle. There's starting to be a black and blue mark from the blood vessels leaking At this point the swelling is still very localized to the lateral side of the left ankle and presumably that's the tendon that was affected (very likely since I really screwed it up 15 years ago and it's got extra play in it) In this picture, taken on Sunday evening about 25 hours after the injury, you can see the edema, or swelling, has spread out over the top and entire lateral side of the foot. There's also more evidence of hematoma at the skin above the metatarsals. At the same time, there's still significant swelling at the original site to the point that it totally eclipses the left ankle. Here's a lateral view taken at the same time as the photo above to show the hematoma bet
