Gabe and i just came back from a yummy dinner at bridge street after each of our respective long days.. It was great hanging out with gabe and talking. We got on the topic of calculus… There was no blackboard around.. So i picked up the closest thing.. A napkin and the squirt bottles of ketchup and mustard. I did my best to describe Reimann sum integration and derivatives using the condiments.. Not sure the waitress (our friend lauren) relished it much ….yuck yuck yuck
Nite all, nite sam
