Dear Pikachu, of course you are surprised. Learn how to expect and evade Team Rocket first.

Also punched cards had around 80 columns, which put a hard limit on the number of characters per line.

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.

 

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?

I started with kickstart.nvim. It was good to understand Lua and how neovim works. Now following LazyVim for Ambitious Developers because distros good, less breakage.

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).

Harder. Stronger. Faster.

Depends on the culture and time if you ask me.

I read Stephen Hawking and I was like, "sure, maybe it helps with the ALS and see the universe".

TLDR: To remove by shaking one would need accelerations high as 24g, which can damage the ear. A couple drops of vinegar or alcohol in the ear will lower the surface tension and make the fluid easier to remove

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!

 
  • Top: is based on votes or comments or both?
  • What is the difference between Hot, Active, New, Most Comments, New Comments?

The Feynman Lectures on Physics (www.feynmanlectures.caltech.edu)
 

The classic transcripts of Feynmans Lectures are now open and free! Some chapters are great to get a different perspective on theoretical fluid mechanics.

 

The JFM webinar series which was a great source of high quality research-based open seminars during the pandemic continues to thrive. It is now hosted in a different platform. It runs every first Friday of the month at 4pm.
