Re: Good Vibrations

I read a couple paragraphs of your article and will come back to it soon. Your warning about the length of the article should be taken seriously. LOL WIkipedia is a source of information authored by the general public. You personally can go into their hrdroponics article and update it where you see ...

Re: Notes To Self

Immigration has been a political issue for many generations. It's only going to get worse as the political and geographical climates continue to change. As you must know there is an enormous problem in Europe. Most of the immigrants there come from Syria and Libya with the UK (England in particular)...

Re: Good Vibrations

Hydroponics is a subset of hydroculture , which is a method of growing plants without soil by using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite...

Re: Al + Hg = Hair

Mom would take me downtown Chicago around Christmas just to look at the store window decorations. They were magnificent but the only one I remember is from Marshall Fields. The store took up an entire block and the window displays were elaborate. All those things you mention about what trains can do...

I recall the Marx Brothers using "Dago" in some of their radio broadcasts. Of course, today that would not be Politically Correct.

Re: Notes To Self

Good to see you posting, Juan. I must apologize for the lack of organization these days. The neglect is due to the fact that we have so few people coming to read or post in our forums. We have become more informal in our structure. Reading through your comments points out exactly how informal we hav...

Re: not just US...

Different cultures have different ideas about race. I'm told there is only one race, by the way, the human race. The way "racism" is used today is purely a social construct. It has nothing to do with biology or science. Our own American history shows how our notions of race evolved out of the conser...

Re: Al + Hg = Hair

I definitely was not a model railroad hobbyist. Most of my playing with the American Flyer was at Christmas time under the tree. Lionel certainly dominated the market at the time, but I liked the idea that American Flyer didn't need a third rail to make things work. As a working teenager I took an i...

Re: Good Vibrations

I don't expect you need to be reminded, but nutrient supplements in the soil is only part of the battle. I found that pH makes a differences as well. I've seen charts that get pretty fine grained about the pH factor and I've always had trouble with it. Not being hydroponic oriented the soil can take...

Re: Al + Hg = Hair

My Gilbert chemistry set and my Erector set were my favorite toys. Lincoln Logs were up near the top as well. While packing things up to move down here we sorted out all the girls' old toys that were in the basement. My mom spoiled the hell out of them and bought everything that was popular at the t...

Re: Good Vibrations

I had a vegetable garden for a hobby at the first house we owned. It was only a couple hundred square feet at the back of the lot, but I grew a lot of different varieties of veggies. Any seed catalog that had something new was a challenge for me to grow. :mrgreen: It took several years for me to get...

Re: Good Vibrations

There are folks who try to tell us plants have feelings, or what you and I would call consciousness. Most of the testing I read about was done with a galvanometer. The researchers were able to demonstrate that tomatoes, for example, showed a sharp increase in the reading when stabbed with a knife. T...

Re: It's too quiet in here lately!

Inspectors are always a nuisance. On the other hand it's often what one thinks is inconsequential that can do the most damage. You know, a Zika infected mosquito can find it's way through that pencil sized hole in the screen door without anyone noting it until it's too late. I don't get the idea beh...

Re: Al + Hg = Hair

I think he ended up using HCl (hydrochloric acid) to prep the aluminum. I recall playing with the mercury from thermometers back when I was a kid and the dangers of doing that were unknown. I'd keep a safe distance from it now, although I do eat fish from time to time.

Al + Hg = Hair

I love science. Chemistry always fascinated me, but I never could master it. Too many weird sounding names. However, I did love the lab work and some of the movies we watched. This one is about 8-9 minutes long and shows the interaction between Aluminum and Mercury. I was amazed. https://imgur.com/g...

Re: I Blamed It On Putin

Corruption in politics has been around for as long as there have been politicians. Couple that with the power that is obtained with ownership of money, and you have a lot of temptation that is hard to resist. The sad truth is that people expect the powers that be to be corrupt to some degree. It's b...

Re: It's too quiet in here lately!

I think the only accurate barometer is the mercury in a cylinder device. Anything with mechanical moving parts is subject to deterioration over time and nonlinearity. Unless you are in need of critically accurate measurements the not so accurate variety of barometer does a good job. Most people are ...

Re: Good Vibrations

The answer to the gang of conscious lightning bugs question depends on how you define consciousness. It's pretty tricky and many people have been working on the idea for a long time; thousands of years, I would guess. One alternate explanation I read came from a neurological scientist. He claimed co...
