From the editor Lewis Page:
"Here on the pages of the Reg the word 'boffin' is a title of honour accorded only to researchers we respect - generally from the proper sciences and able to do hard sums. Lesser practitioners (for instance business-studies or psychology professors purveying dubious surveys and statistical analyses) are generally known as 'eggheads' or 'trick-cyclists', for instance.
We get a fair bit of positive mail from people we have dubbed boffins, so we're fairly sure most of them know this, but it never hurts to be sure."
