# Mathematicians’ Dilemma: anxiety vs. coffee

By tradition and for other reasons, some mathematicians spend some of their time wondering whether stress causes some of their sleeplessness or all of it, or whether coffee causes all of their sleeplessness or some of it, or whether they should direct their worry partly or fully toward something else. Next week, at a conference (the 2012 Joint Mathematics Meetings, at the Hynes Convention Center in Boston) several mathematicians plan to present their tentative findings on this multifarious question:

ABSTRACT 1077-VE-2350. Sumona Mondal [pictured here], Tina Norton, Sarah Andres, Hosana Mamata and Steven Foti. “Using Linear Mixed-Effects Models to Examine Correlates of stress, anxiety, depression to find the factors affecting psychosocial attributes,” The details:

“Caffeine is the most widely used psychoactive drug in the world. One objective of this study was to see what eects, if any, caffeine consumption had on depression, state anxiety, and stress levels of Clarkson students. A second objective was to examine the relationship between the previously listed psychosocial attributes and the participants’ reported average hours of sleep and quality of rest. In Phase one of this study, cross-sectional data was collected via survey from participating students in an Introductory Psychology course at Clarkson University. Phase two of this study examined longitudinal data on sleep, caeine consumption, and psychosocial factors over an 8 week period of time from a subset of students from Phase one. Mixed eects models were used to determine the association between predictor variables of caffeine consumption, average hours of sleep, how rested the participant felt, age of the participant, and sex of the participant, and response variables of stress, anxiety, and depression. Data analysis showed a stronger correlation with stress, anxiety, and depression for average hours of sleep or how rested the participants felt versus the amount of caffeine consumed.

When: The session is scheduled for Thursday, January 5, at 10:15 am.

BONUS: Likely the most famous thing any mathematician has said about coffee is “A mathematician is a device for turning coffee into theorems.” By most (though not all) accounts, Paul Erdos was the mathematician who first said it. And meant it.

BONUS: “A topologist is a mathematician who can’t tell the difference between a coffee mug and a donut — both are surfaces of genus 1. This Demonstration shows a continuous deformation-known as a homeomorphism-of a coffee mug into a donut, then back to a coffee mug.” So say the makers of this video:
