  1. Why is cold fusion considered bogus? - Physics Stack Exchange

    Sep 22, 2011 · In the past, after Fleischmann and Pons announced their cold fusion results, in perfectly good faith, they were proven wrong by subsequent experiments. What are the …

  2. Why do whips hurt so much? - Physics Stack Exchange

    Oct 16, 2018 · The reason, a Whip hurts so much is that the tip of whip moves extremely fast, causing the skin to tear. The reasoning behind this is easy to analyze from momentum …

  3. physical chemistry - Widom-Larsen Theory - Physics Stack Exchange

    Oct 31, 2012 · The renaming is simply an attempt by Cold Fusion folks to politically distance themselves from Pons and Fleischmann, and people have a name for distancing the original …

  4. Is there any reproducible tested evidence for Ni-H cold fusion?

    Palladium Deuterium cold-fusion certainly exists, as tritium was detected by Pons & Fleischmann at Utah, at Bhabha, at Texas A&M by two independent groups (Wolf and Bocris) and also at …

  5. Is velocity defined in the instant a body hits the ground?

    4 days ago · Now, as the ball hits the ground, what would be its velocity? Intuitively, it feels right that it should be 0 ms−1 0 m s 1 since it comes to a halt as it lands. However, if we use the …

  6. Does heat flow from hot to cold here? - Physics Stack Exchange

    Dec 29, 2025 · Imagine there are two bars, one hot and one cold, and they are isolated, unless contacted with each other in which case they are in thermal contact. We both agree that if bars …

  7. Is the E-cat by Andrea Rossi et al. for real?

    Oct 11, 2014 · Rossi's device Unlike Pons/Fleischmann cells, or variants like Arata's or SPAWAR, Rossi is claiming fusion of ordinary hydrogen in Nickel. On the crazy-meter, Nickel-Hydrogen …

  8. optics - Virtual vs Real image - Physics Stack Exchange

    I'm doing magnification and lens in class currently, and I really don't get why virtual and real images are called what they are. A virtual image occurs the object is less than the focal length …

  9. What are the challenges to achieving cold fusion?

    while this is informative, it is wrong to demand "peer review" in this case, as peer review is just censorship. The stuff you link to, the "surface polaritons", the NASA stuff, the Rossi crap, this …

  10. Rotating disc and current? - Physics Stack Exchange

    Aug 25, 2024 · where E E is the total electric field. As a consequence of Maxwell's equations, the conservation of electric current (divJ = 0 div J = 0) holds, and we use Ohm's law J = σE J = σ …
