  2. Capacitor experiments?

    Thanks too for the good reply. Do you have a link or info to reinforce getting me on track there. E.g. both polarities moving in a wire? I though only electrons (if they can be called that) hopped around because the heavy nuclei were bound (=bonded) as solid. I suspect the 1990s confusion was the vast amount of older literature with conventional flow sabbotaging progress. All literature (that made any reference to electricity) needed review. For then mission impossible. But I don't know the issues. Now (it looks to me like) we close an eye (& make a compromise) to get around the (polarity confusion) problem. (?)
  3. Yet another possibility for Fermi's Paradox

    Why wouldn't there be? I don't think we (humans) have a definition for life which could be applied beyond earth. All life on Earth has the same number of DNA base pairs. We only know of one type of life and any thing which deviates from earth life would possibly be either unrecognizable or classified as some sort of autonomous chemical machine. This is a point which has always stuck me. Why hasn't there be other genesis of life here on earth? If we are truly in a "Goldilocks" zone and "Earth-like" planets are most ideal places life might form than why has it only happened once here on earth? This points to one of your arguments; no shame in admitting we don't know.

  5. Yet another possibility for Fermi's Paradox

    Let's try this again! Lost it all last time... Exactly! We have one data point, you cannot deal in probabilities with one data point. To me the Fermi Paradox is more an admission of ignorance than a genuine attempt at determining the probability of life on other planets. We should get used to saying "We don't know" no shame in not knowing, the shame lies in saying you do know when you cannot know... Again, we have one data point, a curve cannot realistically be drawn from one data point. Until we get more data saying that one alternative is more probable than another is nothing but baseless speculation. Now if we find life in our solar system, life that points to a second genesis of life, then we will have reason to at least be hopeful. But if we find a second genesis of complex life here in our own system then all bets are off...

  7. I found out that the votes for the statewide youth and government program were tampered with. Voter fraud! In a youth and government program!

  8. Nice. You made me think about it a bit more as I hurtle down the motorway. I did a quick search and found a paper that estimated the mass of iron around one supernova to be about half a solar mass - which sounds like a lot of iron. Not sure how typical it is though. That is about 150,000 earth masses. The earth is about 1/3 iron, so enough for 450,000 earths. There are about 100 billion planets in the galaxy so (if they were all earth-like) that would need more than 200,000 supernovae. Does that sound about right?

    Also, conviction differences tells us nothing about the likelihood of persecution. In cases of sexual assault and rape there are two major elements. First,is the low rate of actual reports, which is roughly comparable between males and females (<10%). Regular assault has a reporting rate of ~40% in North America. Second, even after reporting cases, conviction rates are very low for a number of reasons, including lack of evidence and high attrition rates (again, <10%). In other words, victims have a hard time to have perpetrators convicted. When we look at when charges are actually filed rather than final convictions, we find that (again using Canadian and US statistics) ~20-30% of all reports result in charges (again, not convictions). Interestingly though ~20% of cases are dismissed as unfounded. That is interesting, as depending on study, the estimated rate of false accusations is somewhere between 2-8%. Moreover, the rate of dismissals is higher than e.g. for non-sexual assault (~10%). In other words, sexual assaults allegations, once reported, are dismissed at a higher rate than other crimes. There are studies looking into these aspects and one (forgot the author) indicate that the characteristics of the victim, more than the circumstances determine whether police starts investigations. This includes judgement of the "moral" character of the victim, rather than, surprisingly, witnesses or injuries. I think the study was limited to a specific region and may not be universal, but it is interesting, nonetheless.
  10. Yet another possibility for Fermi's Paradox

    "Unlikely" is probabilistic terminology. Indeed, the so-called Fermi Paradox is said to be based on probabilistic argument: Drake equation - https://en.wikipedia.org/wiki/Drake_equation Lets have a look how the probability in question is calculated. From wiki: We can see immediately, or we can read it in wiki, that number of parameters are speculative with ranges varying greatly. Then the question to me is, how useful such estimation of probability is and if its possible to base any sound argument, the so-called Fermi Paradox in particular, on it.

    The thing is they don't have to be big and scary. I have been trying to teach leprechaun who does my washing up to write my posts for Scienceforums.
  12. Powerful Men, Beautiful Women, and Sex

    Thanks for sharing, Raider. In order to be context relevant, however, we should instead be looking at the metrics relating to how often women are believed when speaking up about sexual harassment and assault versus how often men are believed when denying it (ideally against a backdrop of numbers clarifying times when it actually happened and times when it was a false accusation, but that's a statistic that's obviously quite impossible to find). Given this, we need to look at motives, and is SO many (most?) of these cases there's simply no good reason for the female to lie (there are exceptions, but I'm referring to the majority), and practically EVERY reason for the male to lie.
  13. Yet another possibility for Fermi's Paradox

    If in that very unlikely chance that we were alone, it would certainly raise far many more questions then the more likely alternative.
  14. Yet another possibility for Fermi's Paradox

    I can't say that, while I consider it to be unlikely we are alone that in of itself says nothing about the facts or lack thereof. I would be amazed if there is no other life in the universe, in fact I would be amazed if there is no life in our own solar system other than us but at this time I can't see how a belief says anything about the facts...
  15. Help me identify a bacteria

    its catalase +, oxidase +, ferments glucose and produces gas from the process, and is a gram + facultative anaerobe and its highly resistant to antibiotics and motile + and has been seen to grow up to temps of 103°F, colonies are white and turn slightly yellowish, orange after 2-3 days, small punctiform colonies. Colony elevation is raised. Colony margin varies from complete to irregular, odor is pungent and has an odor of ammonia after several days
  16. Yet another possibility for Fermi's Paradox

    I'm a firm "believer" that we certainly are not alone in the universe, despite any real empirical evidence to support that belief. I believe most cosmologists are also of the same opinion. The sheer enormity, scope and near countless numbers of galaxies and stars in our observable universe, plus the fact that the stuff of life being everywhere we have looked, supports that general belief. We are situated on a small terrestrial planet, orbiting a humdrum dwarf star, situated in the outer suburbs of an average size galaxy, among many billions of other galaxies in the observable universe.

    Well sure, Deepfoot is real, we know that. You'd be shy and elusive too if you were under such incredible pressure.
  18. The fact that the terrestrial planets are closer to the Sun then the gaseous and icy giants, actually support the accretion disk theory re planetary formation. And also in recent times, various stages of stellar system creation has been observed in distant systems. The heavier elements are more inclined to fall towards the center, [to create the terrestrial planets] along with the fact that closer to the Sun, the lighter elements such as Hydrogen Methane etc were prevented fro condensing due to higher temperatures. These lighter elements went into into creating the icy gaseous giants further out from the Sun, where temperatures were more conducive.

    Everyone knows they only hold nuclear wars on mars in the odd years...
  20. Capacitor experiments?

    Yes. The right sequence is to start by learning some science. If you can also learn how to stop your text appearing like this it will be a step forward too
  21. Fantasy beasts and where to find them.

    Many people seem to have a need for mystery, spookiness, and paranormal concepts in their life, that according to them, science is unable to explain. I belong to another forum that is fast losing respect as a science forum simply because it is dominated by weirdos who honestly believe in ghosts, goblins, Bigfoot and even some nonsense re a nuclear war having been conducted on Mars by Alien beings! I kid you not! https://www.express.co.uk/news/weird/745738/Life-on-Mars-wiped-out-nuclear-war-Dr-John-Brandenburg These types of people will always prefer the "u tube" video on the net as proof that mainstream science and "powers that be" are conspiring against the general populace. Popular TV series such as "The X-Files" and "Millenium" certainly have a lot to answer for, and the poor gullible and impressionable Idiots that they have gathered along the way. Yes sadly there are real people who still believe in this sort of nonsense.
  22. Galactic distribution of heavy elements

    OK, I will think about it. I have to admit I don't know much about them but here goes. Almost all the mass of the solar system is the Sun, and it hasn't got much iron in it (0.003% by number of atoms I believe) If I make the (dodgy) assumption that all the other stars and planets in the galaxy are similar then I conclude that the galaxy hasn't got much iron in it.
  23. Powerful Men, Beautiful Women, and Sex

    It also included how often men are convicted when accused, and how often women are. The system usually believes the women, whether they are accusing or defending. Hence, not a system that is automatically bent on disbelieving women. Sexual in nature or not.
  24. Fantasy beasts and where to find them.

    Perhaps these responses are a bit harsh and some humility is in order. I have been frankly amazed (along with many others) at the fantastic creatures shown on Blue Planet II by David Attenborough. Remember more people have walked on the Moon than the very bottom of the Pacific Ocean.
  25. That's where all the physics is. Why? They have opposite charge. Such a model ignores conservation laws (lepton number, for example). Failure indeed. What "model" are you using? A trajectory (positions and velocities)? Why can't you find the energy from the values you use? KE = 1/2 mv^2, and PE = kQ1Q2/r If your model doesn't predict the energy levels of the hydrogen atom, of what value is it?
  26. As I said, but you didn't acknowledge, when you start using words for the purpose for which they were intended, rational discussion can move forward. You have the germ of an idea which lies somewhere between the Thompson 1904 'plum pudding' model of the atom and the Bohr 1913 orbital model. Probably quite close to the Rutherford 1911 model. However, they all called Helium, Helium and Hydrogen, Hydrogen. That enabled discussion. There was a great deal of head scratching in those days to come up with these three models and the history is quite interesting and pertineent to your ideas.
  27. Fantasy beasts and where to find them.

    In the last few years we've quietly disproved most of these things. Almost everyone in the western world and many people in the world in general now all carry acceptable quality cameras with them all the time. Yet good photos just hasn't appeared.
