Have you ever published in a peer-reviewed journal? How is?
swansont replied to Wigberto Marciaga's topic in Other Sciences
Yes. The requirements are specific to the journal. As I recall, the process generally took several months for peer review, revisions and publication. Submission dates might be included in the article so you can check for yourself e.g. a recent one from Phys. Rev. Lett. Published in April “Received 7 September 2023 Revised 11 January 2024 Accepted 26 January 2024”- 1 reply

do you believe in future and useful h2-airship?
swansont replied to harlock's topic in Other Sciences
In what situations? -
Clouded over - nothing but a diffuse bright blob, at best, and it got kinda dark for a while.

Did contaminated fuel cause the Baltimore bridge disaster ?
swansont replied to toucana's topic in Engineering
Another cargo vessel lost power near a bridge but was being escorted by tugs. https://abc7chicago.com/verrazzano-narrows-bridge-new-york-apl-qingdao-cargo-ship-loses-power/14634032/# “The U.S. Coast Guard confirmed the container ship "had experienced a loss of propulsion" Friday night as it traversed a waterway in New York Harbor.” I’m guessing this happens relatively often but we just weren’t aware because near-misses usually don’t make the news -
Can you provide evidence of quantum transitions at such low energies? Neutrinos do not interact electromagnetically. You’re building speculation on top of more speculation, and give the appearance of just making it up as you go. ! Moderator Note The charade has gone on long enough. This doesn’t fulfill the requirements of speculations, despite ample opportunity to comply. Don’t bring this topic up again

No, I want to know how photons are generated in a solid given your model. Photons don’t just sit there - they move at c - so they are either absorbed, or they leave the material. We can know the rate at which they leave, since it’s dictated by the Stefan-Boltzmann law. But once the photons are absorbed inside the material, which will happen quickly, how do you get new ones? (Once we can calculate the heat capacity, we can find out how many photons there must be)

Who measures time in such experiments with a spring-driven clock with gears? Mechanical clocks lack the necessary precision. But time dilation is symmetric. Clock 1 will run slow compared to clock 2, from clock 2”s perspective. How can a mechanical effect have a clock run both fast and slow? It can’t. Time dilation isn’t a mechanical effect It sounds like you think there is an absolute rest frame.

I just moved, and am a few hours outside the totality region, but was too occupied to arrange to get inside the zone. And am too wiped out to contemplate travel at this point.

That’s still radiation, and I’m talking about conduction transfer from one material to another, not through a material. When two materials touch the heat transfer rate is much larger than if they are separated by a small amount (especially if that is a vacuum gap) This is inconsistent with the heat transfer being radiative. You burn yourself when you touch the hot water. What does the S-B law say is the heat flow from touching your 1 cm^2 fingertip to the coffee?

Particle Accelerator Breakthrough
swansont replied to grayson's topic in Modern and Theoretical Physics
Free electrons can’t absorb photons; you can’t conserve both momentum and energy if that were to happen. They scatter photons, giving you a lower-energy photon. (Compton scattering) You can absorb a photon in the photoelectric effect because the atom is there to let you conserve momentum. But: acceleration of electrons with light has been done, in various ways https://www.nature.com/articles/s41598-019-55472-5 https://physics.aps.org/articles/v6/106 -
Self-made means you did it yourself, with minimal outside help. Not just help from parents. It suggests that anyone can do it if they just work hard enough. There’s a baseline of support that anyone can get, but most uber-wealthy get far more than that, such as subsidies or tax breaks for individuals or companies not available to the average person. If someone hands you a million dollars and you can parlay that into a bigger fortune, good for you. But since most people don’t have access to a million dollars, it’s a tad insulting to imply that it’s a path to wealth accessible to all.
