@ACuriousMind Show an error flag in case of such conflicts? Catch the error by making it mandatory to use the reply button OR pick the username from a list of usernames (which also shows the avatars alongside). That would prevent annoying pings (in those cases where it unintentionally pings another user sharing the same name string)

They already have a list of names followed by avatars. Like when I tying @acu already your name and avatar shows up

Just make it mandatory to click on it in case of name conflicts
@Blue It's of no use to provide the list - you'd have to change the entire way non-reply pings work - currently they work by matching the string after the @ to the start of usernames (e.g. that @acu also pinged me). In order to do what you want it to do, they'd likely have to work by user-id

I can already imagine the annoyance @rob has to face when a his inbox is filled with replies meant for another Rob
@Blue Also, what about people on mobile? Using the autocompletion on mobile is a pain depending on your screen size (and I'm not even sure it shows up in all versions).

The new chat UI for mobiles does have the autocompletion option and it's pretty convenient too. Tried it on several Android phones (ranging from small screen ones to 10" tablets)

As for what versions it supports, I'm not sure. But it should really work on all recent Android models as well as iOS

But if it doesn't support any of the modern OS's, then they should work on releasing new updates for them!
Hamilton's action for classical systems has the units Joule seconds ($\rm J\cdot s$), which in base units is $\rm kg\:m^2/s$.
Does the $\rm m^2$ have anything to do with area?
I'm having a hard time "reading" the units here.
Negatives are my enemy. I used to also have an issue with square roots losing or eating things, but then I started drawing a line down at the end of them
I do still sometimes get terrible confusion when computing things in different frames. At least I've realized that $\mathcal{S}, \mathcal{S_0}$ is a terrible pair of names for frames
@enumaris also do you know why these theories are built upon the idea of a time dimension? i never understood why we considered it a dimension as it is not something that we observe
naturally like we do geometry
actually nvm i guess we do observe the passage of time i'm mistaken
it's not as direct of an observation as our sensation of space like when we touch a sphere or look at stuff. it's more of a recognition that things are changing
That time is a "dimension" on equal footing as the spatial dimensions comes from special and general relativity
SR and GR posit space-time as a 4-D Lorentzian manifold. Pre-relativity physics space-time had more of a fiber bundle structure where space was fibers on a universal "time" axis
