nacturation writes "Everyone loves Gmail. But not everyone loves email, or the digital era. What ever happened to stamps, filing cabinets, and the mailman? Now with Gmail Paper, you can request a physical copy of any message with the click of a button, and it'll be sent to you in the mail. Photo attachments are printed on high-quality, glossy photo paper, and secured to your Gmail Paper with a paper clip. And it's totally free: the cost of postage is offset with the help of relevant, targeted, unobtrusive advertisements printed on the back of every print."
Mathematics deals exclusively with the relations of concepts
to each other without consideration of their relation to experience.
