    The problem with a fixed price is you have to always calibrate it according to the economy of the user's geolocation. What is cheap for a person from a developed world may be unaffordable for a third world county.

  • Is there no electromagnetic force between the positively charged nucleus of an atom and the electrons?
  • The follow up question would be the opposing force which keeps them in orbit(als)? This balance of force was called the planetary model which has this shortcoming that electrons might fall into the nucleus.

    If electrons actually followed such a trajectory, all atoms would act is miniature broadcasting stations. Moreover, the radiated energy would come from the kinetic energy of the orbiting electron; as this energy gets radiated away, there is less centrifugal force to oppose the attractive force due to the nucleus. The electron would quickly fall into the nucleus, following a trajectory that became known as the "death spiral of the electron". According to classical physics, no atom based on this model could exist for more than a brief fraction of a second.

    I am trying to recall what kind of forces enable the orbitals of electrons according to Quantum Mechanics.

  • Is there no electromagnetic force between the positively charged nucleus of an atom and the electrons?

    Or in other words which forces keep electrons in orbitals and prevent it from flying away or crashing into the nucleus according to modern understanding?

    Why are so many people so fixated on Lemmy's growth?
  • The flagship communities are quite alive, but the niche communities have not really taken off. I am talking from both the absence of such communities, and my experience trying to migrate !fluidmechanics. The subreddit has around 10k humans (or bots).

  • We are free to learn, but learning is not free.

    Freedom vs cost. One cannot pickup a skill without time, effort and more importantly access to guidance and a vast library of content. Same applies to man or machine. The difference is how corporations have essentially reinvented piracy to facilitate their selfish ends after decades of dictating what's right with DMCA, DRM and what not.

    > Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are: > > - computation fluid mechanics > - scientific programming and HPC > - nonlinear shallow water equations > - statistical description of turbulence: spectra, energy budget etc. > - experimental methods: PIV > - stratified turbulence > - academia > - navigating your career pre- and post-Ph.D. > > Ask away!
