White boards are good because you can reorganize stuff very easily. Writing on paper with a pencil leaves a mess when you want to tweak the same diagram over and over again.

You may ask, why not just draw it over again on another page or why not just draw it right the first time. The issue with these is that sometimes you'll find yourself dealing with really complex diagrams and you'll want to refactor parts of it at a time while leaving the rest untouched. Many times you have no idea how the structure will turn out from the get go and as you refactor things you'll find the structure changing in unexpected ways.

I've found whiteboards invaluable for programming, design, database design, and a bunch of other applied stuff. I'm actually in pure math though and to be honest I haven't found them as useful in the field unless I need to explain something to someone else (in which case they are again invaluable). That's not to say that there aren't times when whiteboards aren't useful. Geometry, Graph Theory, any of those seem easier to work with on a whiteboard. For example if you're doing group theory with graph theory and you're given a set with the intent of finding generators (again, more applied) then the cayley diagrams of any generators you choose can change and vary a lot. Isomorphisms, normal subgroups, etc.. all of those are also easier to approach on a whiteboard.

whiteboards are excellent for brainstorming. you don't fucking write essays on it, that's retarded. you write a formula or a draw a diagram, then step back, and consider what the fuck you just did and where you could go from that.

but you don't understand that, because you're a lawnmower.

As in the only reason people do it is because they saw John Nash in that movie doing it and thought he was a genius. If John Nash had drawn his math on the tiles in the shower then you'd have idiots doing that too.

I don't think he actually even wrote on glass. There were a ton of discrepancies between the movie and John Nash's real life. The different women he'd been with were combined into one wife, the estranged son, the many bouts of craziness, etc.. Even the game theory argument in the movie is retarded.

His schizophrenia in general had a very different nature, for example it made him believe that everyone who was wearing a red tie was actually a communist agent.

The movie is well, just a movie.

>> No.5726011

>>5726000
yeah i used rustoleum.

staetdler markers are very stubborn to erase on this board...and staedtler is a decent brand right?

in general most marks would not erase w/o serious elbow grease. we e-mailed rustoleum and they suggested using a mr clean wipe. works quite well (don't even need to wet it) now but it was annoying at first.

also you really have to sand the wall thoroughly under the area where you're going to apply--i did not do this and i feel it lead to some of the erasing troubles.

may have misspoke saying i would never do it again, but i would for sure not recommend rustoleum brand. the massive amount of space is quite nice though.

you can get rustoleum for 35 bucks at home depot, but my experience was not optimal. i would recommend sanding the surface thoroughly if you use rustoleum and/or shopping around for another brand. check reviews on amazon, stuff like that.
