| Dear John, Happy Pi Day!
As an OCW learner, you’re an important part of the MIT community and our efforts to open up MIT’s courses and pedagogy to the world. If you are able, please consider a gift today during the MIT 24-Hour Challenge to help us sustain and advance this mission for learners worldwide. If 300 people support OCW before 11:59 pm ET today, we will unlock a gift of $5,000 from OCW learner Richard. Join alumni around the world and friends of MIT like Richard by supporting OCW during the MIT 24-Hour Challenge. |
