  1. The possibility of resettlement on other planets. The problems are beyond counting. But, "never say never". This universe is not yet dead.
  2. No scientific exploration; just plain fun. "The times, they are a-changing". Since I don't like flying or heights, you all go and send back word of your experiences. Keep us posted.
  3. https://www.sciencenews.org/article/earth-plate-tectonics-volcanoes-earthquakes-faults Shaking Up Earth" by Carolyn Gramling. (from Science News, January 16, 2021) "Earth is the only known world with plate tectonics. It's also the only one known to harbor life." It is a long article about plate tectonics and the history of its discovery and proof. But, the part I want to point out is "Crucible of Life" about half-way down the screen. I have never heard this before and do not know if it is a new idea or not. The thought is that life "might have" or 'perhaps could have"
  4. John D hit the nail on the head. That is exactly the school system that I passed through. And I fell for it. Adults were perfect, knew everything and were never to be questioned. It took me a long time to outgrow that and I'm not sure I ever fully did. When I started teaching, it was like pulling eye teeth to get those children to think for themselves, to argue and debate and put out their own thoughts on topics. I fear I was a failure at the effort. Almost none "got it". Parents told them "teacher is always right". Well, this teacher was not always right. Nor were many of her fello
  5. This protest is purposely on this thread because this is where the problem is. Will someone PLEASE tell me what is going on? I have tried over and over and over to put one simple post here and all have been interrupted and lost. I have tried "Contact us" but I get no response. PLEASE?
  6. I bought a calculator that came with a zinc carbon battery, which I'd never heard of. I've read notes giving general explanation but they don't mean much to me since the notes use more "foreign" terms. Can someone tell more about zinc carbon batteries? I mean is there anything special I need to know? Also, when this battery dies, can I replace it with an alkaline battery? Thank you. hazel m

    Body Proteins

    I know about the proteins and their enzymes with all the work they do. My Question is "do scientists know exactly how many of these proteins there are?" I am wondering because they seem to have IDs. Maybe not all have IDs but I've read of several. For example, this morning I saw GPI1 and POU4F3
  8. There is no doubt that the changes in our culture started long before Covid but it didn't help. Also - what I think the article is getting at - they are showing that those who had not accepted and joined the new and changing culture felt even worse as they got shut down. This new culture is confusing enough without the sudden situation that none of us are used to. Every generation changes things and this latest was already drastic. Then came Covid. A double whammy.
  9. From Neuroscience News https://neurosciencenews.com/coronavirus-brain-16972/ Both interesting and helpful toward dealing with the problems.
  10. Yes, there is a place for rote. But, as you mention, process needs to come - I really believe - first. Just a good glimpse so the student realizes what it is he is memorizing. Skipping this is why so many don't get it. They never realize that multiplication is just a fast way of adding and division is nothing more than a fast way of subtracting. I do remember someone once telling me that learning the process made it unnecessary to memorize the tables. He/she was saying that they would automatically remember the combinations without ever going through the rote exercises. I could see t
  11. I am not sure I can agree with that, Thoth. Halfway up the "I'll try" scale are those who keep at it but end up doing a very mediocre job and no amount of more trying improves them. Each end: failure (giving it up) and success (fist class producer). No, if we all have given talents, then it stands to reason there are some things each of us cannot ever learn.
  12. Ah! Thank you, GAHD. Plasticity, of course. I seem to be analyzing the problem without considering the cause. Same as with the body. You can't cure (or learn to deal with) the problem if you do not know the cause. And that gets back to the doctor's (and my) complaint. We are bucking the trend and, as the doctor said, maybe it really is too late to"fix it". Should we even be thinking of fixing it? And I see that as my years advance. Early on, I had no trouble at all accepting what the next generation was doing. I actually defended them against complaints. Now? Don't even ask.
  13. I am hoping there is a teacher here. I have a question for teachers. I have been pondering the fact that young students take to the electronic technology with ease while older people struggle with it. Andy Rooney had a good answer for that. "The reason we elders have trouble learning new things is that our minds are already full of all the wonderful things we learned years ago." Very good. I do not think that is an alibi. Our memories are with us. Our brains are already working full time. However, there are also older people who take to this technology with relish and have no tro
  14. I used to argue with a doctor who felt the world was going to pot (and he did not mean the little green plant). I would tell him those of the sixties had straightened up and done great things. So would those with these new ideas. He would say "Not this time; it is too late.". I have now come to agree with him. This notion of turning ourselves into computer-controlled robots scares me. All I can say is thank goodness I will not be here in 2045. Pray that - as in Orwell's "1984" - you have a few renegades.
  15. I don't know, GAHD. Much as I respect your views, I go with Thoth on this one. Even parts of your posts seem to lean his way. Are we making robots of ourselves while we try to make humans of robots? And we lose much. The simple fun of learning and creating may not be the be all-end-all or our lives but do we want to give it up to a button plugged into our brains? That is not a big deal compared to other things you and Thoth are talking about but they are us. I do not really want to become a robot. And that is what we become with this implanted mini-computer plugged in. As in real li
