Jul 22, 2019 at 18:03 | comment | added | Alec Rhea | Whiteboard markers also have potential risks, but chemicals like xylene and methyl isobutyl ketone evaporate over very short time spans and distances from the board and are only really dangerous if you sniff the marker (or leave your face right up against the board as you write, like me). | |
Jul 22, 2019 at 17:55 | comment | added | Alec Rhea | @AsafKaragila On a slightly more serious note, chalk has potential adverse health risks (aaqr.org/files/article/569/9_AAQR-15-04-OA-0216_2596-2608.pdf) In particular, the linked study found that chalk use leads to "irritation to the eyes, skin, respiratory tract, mucous membranes, and digestive tract", and that for chronic users like mathematicians "the potential chronic health concerns are lung and liver damage resulting from exposure to calcium sulfate and calcium carbonate particles, respectively." I still use it, but view it like smoking (a guilty pleasure, not in classrooms, etc.). | |

When I need a break from tough questions like that, I like to relax with a nice, hot donut of coffee, and a maple glazed coffee mug, from Mathin' Donuts, visit today! For a limited time only, buy one, get one free, with code Banach-Tarski. | |

Jul 9, 2019 at 20:06 | comment | added | Somatic Custard | I don't have a strong opinion about blackboards vs whiteboards, but chalk is unquestionably superior to markers. Since chalk doesn't write well on whiteboards, I can only conclude that blackboards are the way to go, and users of whiteboards are heretics. | |

Jul 9, 2019 at 10:06 | comment | added | Alec Rhea | @AsafKaragila I will give my life in this holy war; whiteboards, just as god intended! | |
