The Place of Value in a World of Fact

In a previous discussion the subject of does life imply some kind of awareness came up. I know it's a kind of taboo subject among scientists who want to keep their precious distance. But the subject came up. I don't know what awareness means really--it has something to do with a process of making de...

Thanks. It is very much a work in progress. You tube wouldn't take the file of a dozen pictures or so. It just referred back to You Tube. When I tried to upload to You Tube, the software only took one sequence (out of a dozen). Then when I tried it again to upload the whole thing, I got an error say...

Re: Internet Problem

Wow! Thanks a lot. I didn't know you could do that. With the aid of my son, I did find the old software just this afternoon and installed it. I think I'm back. If it doesn't work--or even if it does, I will try to get back up this afternoon. Thank God for friends and family.

Please Come

The ghosts
can only sneak up.
They're very hard to spot
from this vantage point
where things don't
see ghosts.

They don't try
to hide but
ghosts can't
will to be seen.
They may want to
grab a place in your
friendly world.

They weep
not because they are ghosts
but because
they are alone.

On a Day Off

It's an unpredictable misery. Even on a quiet day when there is no one to disturb you. A small switch is turned and the lights of day flicker and threaten. How long has it been since you were scared? It's a state in decline. It makes some demands. You have to be in a priveleged state of vulnerabilit...

When the doctor said, "You didn't die, Donny. There will be tomorrow." I looked at her with glazed eyes. "This place isn't so great but it made good children." The sun was shining. The Spring was going to start. I rubbed shoulders with fear and the contact felt good. Fear does not have a cold body. ...

Internet Problem

My internet provider decided to upgrade its services. I couldn't get the new site installed because I couldn't get the old password right (I guess I lost it). They are not patient about such problems. If anyone has any suggestions I would appreciate it. I am just an ditzy old man but I love you guys.

Carrot Peel

The carrot is technically part of the root system of the plant. It is not a typical root because it has a lot of sugar in it. The cell structure resembles that of a fruit. Anyway, the carrot occupies a category all its own.

Biofilm Here to Stay

I see the protists moving around but rarely see any direct contact between them. My guess is that they are absorbing nutrition from proteins floating freely in the water or they are being fed by invisible nutrients--perhaps absorbed directly from the water. In that way they act like plants. https://...

Ambiguity Complexity and Confusion in a Leaf

As amateur students of living structure, we sometimes find the structures we look at to be very straightforward and predictable. However, more often the structures are buried inside each other and under each other and are ducidly hard to see. In this small piece of rubber plant leaf, sometimes the r...

A small branch of one of the houseplants had been disconnected. The flow of its vital substances had been discontinued and it has been disowned by the plant.
