  1. Soap lowers the surface tension of water so the molecules break up more, making both the water and soap more efficient at cleaning.
  2. Help me with this, please. Are you talking about the ring that's left when you twist the top off a bottle of water or soda? If you're going to worry about that to the point of wanting it disinfected, why don't you just cut it off with a knife or scissors?
  3. Or some thing. Drones could carry some small weights, but I don't think most can lift an air tank. How 007 would it be to swim up to the boat and have a fleet of drones take your SCUBA gear from you, like aerial butlers?
  4. If you learn to be the best oatmeal raisin cookie baker ever, I'll place a monthly order. I loved the episode in the first season of Friends where Phoebe claims to make the world's best oatmeal raisin cookies in the world, and Rachel is amazed when it's true. Phoebe tells her "Oh, I don't make them very often. It's not fair to the other cookies."
  5. But with the black hole, the EH represents an area where gravity curves spacetime intensely. I was wondering if, approaching a neutron star, there would be a similar but less intense curvature. I remember Larry Niven's fictional life on a neutron star, and dealing with a surface gravity billions of times stronger than Earth, but I can't remember if he wrote about any Earthlings trying to approach it.
  6. I had assumed (bad, bad!) that having 1.3 - 2.5 solar masses squeezed into a 12 mile radius sphere would generate an area where the gravity would become suddenly intense, similar to what happens when the matter overcomes neutron degeneracy as well. If one were to approach a neutron star in a space vehicle, would it feel the same gravitationally as approaching a normal star of such mass?
  7. From the link: The "intense gravity" comes from the matter that has overcome electron degeneracy, right? Does a neutron star have a calculable event horizon at which point this gravity becomes "intense"? Does the "high-speed rotation" create the "powerful magnetic forces"? I'd always thought a neutron star was inactive, a dead star, but a magnetar seems capable of quite a bit of illumination.
  8. We tell ourselves stories about ourselves in order to deal with our lives, and when those stories are good and positive ("student who's excited about applying knowledge learned in studying Computer Engineering to real life situations"), they can be motivating and inspiring. When we tell ourselves bad and negative stories, they can be depressing and draining. Sometimes it can be as simple as changing the story you tell yourself. It's true that we often tell ourselves there are things we don't feel like doing, and if we keep thinking that way we'll probably not do them. We tell ourselves we'll get burned out if we study too much, or we tell ourselves it's too much trouble to get dressed up for that party we'll probably be bored at. But we've all experienced those times when we tell ourselves something different, something positive, and suddenly we're motivated enough to do the thing we've been avoiding, and then we find it wasn't so bad after all. In fact it was pretty great. What you obviously need to avoid is letting this "I don't feel like doing this" feeling be random. Set aside some regular time when you do absolutely nothing, instead of allowing yourself to goof off at a time when you really need to be studying. Tell yourself you're now "student who gets their studying done early so they can spend the rest of the day watching YouTube videos without guilt". If necessary, print out some inspirational phrases and hang them up where you can see them regularly. Many people tell themselves awful stories about themselves in the privacy of their minds, and they forget to remind themselves how utterly awesome they are, and how far they've come, and how much they've learned in so short a time. Don't forget that your brain came at great sacrifice to the rest of your body. Birds gave up much of their physiology in order to fly, and your species did the same to evolve that brilliant brain of yours. Tell yourself better stories.
  9. ! Moderator Note I want you to understand that what you're doing is NOT discussion. You've adopted a stance, and you've presented it, but when confronted with replies that refute what you're saying, using mainstream science understanding, you choose to ignore them instead of researching their validity and taking them on board to adjust your arguments accordingly. This shows us you don't understand what the refutations are explaining, which is further supported by your initial misunderstandings. You don't seem to know enough science to understand why it's unreasonable to make the assertions you make. In other words, you aren't listening, you're soapboxing. You're continuing to make the same claims even though they've been shown to be wrong. You seem to be caught in a loop where you can't learn why you can't learn these things, and unfortunately this behavior breaks a few of our rules. Nobody wants to waste their time if you aren't going to listen, yet EVERYBODY would love to see that you actually learned something from these discussions. Fair warning that folks are starting to report your posts as a waste of time, so if you can figure out a way to support your ideas better, or actually reply to what the other members are trying to tell you, it might keep you from getting banned for rule-breaking. And let's be clear, if you're banned it will be because you broke the site's rules, not because you broke Einstein's theories.
  10. If you can suggest he was corrupt and intellectually dishonest, you don't have to actually study his work. Huge time saver for the ignorant.
  11. The model it's based on takes us back to a point just after t=0, but nothing about either model or theory says that's when time itself started. It's just the beginning of a universal evolution from an extremely hot, dense state to our present configuration. Beginning of an era, rather.
  12. But how can this argument rise above the No True Scotsman fallacy? With over 9000 recognized sects, which contexts in Christian belief are thoughtful and which aren't?
  13. Vane efforts are like building a turbine. Vain efforts don't yield the expected outcome. Vein efforts are when we see blood vessels stand out on your skin.
  14. The signal we're looking for is always buried in noise, and alone we can only sift through so much. Discussion helps a lot, and your contributions are welcome.
  15. Unless you prefer the simplest cookie over anything else, or think the baked color is the most important part of the cookie, I don't think this is possible. A default sugar cookie is only ever going to be satisfactory if you're looking for any other factors. But perfecting a simple cookie is going to teach you some mad baking skills along the way. Someday you may want to go nuts, or spice things up, and you'll know how to think outside the oven because you learned the oven so well. Let us know how well they turn out. Yum! We may need a whole other thread for what to have with them, milk or tea?
  16. Computer or phone? I've noticed my phone OS is much more aggressive lately with ad tabs that cover what I'm trying to read, but nothing like that on my computer.
  17. When I read studiot's post, he seems to suggest your conclusions were adversely affected by mistaken assumptions. He does NOT seem to suggest that ignorant people should stay away from the forum, or that one should only ask questions one knows the answers to. In fact, he includes some information to help dispel some of the ignorance you admit to having about the subject. Ignorance is NOT stupidity, it's simply a lack of knowledge about a specific subject.
  18. You DID pull that off, way to go! I recently had an epiphany about bicyclists. In my area, they often give bicycles about 8 inches of asphalt to the right of the solid line on major, one-lane roads. My apophenia lumped all these cyclists together as "exercisers" and "hobbyists" and "those practicing for a tour/race", so I got annoyed that they often chose early morning commute times to cycle in their clingy outfits with sponsor ads all over them. Then someone pointed out that many offices have showers for employees that cycle commute great distances. As soon as I realized these cyclists were probably fellow commuters instead of hobbyists just out for the exercise, my whole attitude towards them changed. I had misinterpreted their presence.
  19. Are you actually trying to pull off an Appeal to Age fallacy in this thread? Bold move, Methuselah.
  20. Our Guidelines link to RationalWiki for logical fallacies: https://rationalwiki.org/wiki/Logical_fallacy
  21. Staring into the shadows can cause imaginary predators, so I'd imagine there is a comforting corollary for imagining angels.
  22. Do you really think ALL decisions need to be respected? Perhaps you're using definitions of "respect" or "anyone" with which I'm unfamiliar.
  23. I refuse absolutely. Some ideas should never merit anyone's respect.
  24. Fear, stupidity, and Vitamin Duh. I wonder if I can market some heated boots for those worried about falling through the ice when fishing? Or maybe a special red cape to identify those who don't want to be near bulls?
