Coming from a middle class family from a

small town in India. Never had the luck and

guidance to reach Stanford for education.

Guess what? God has sent the opportunity

right across my door step! Heartfelt thanks to

the great team and teachers who made this

happen! (Akash Goswami)

I'm learning this from home because my 3

month old daughter was diagnosed with a

rare immune disease and is still receiving

her bone marrow transplant....[She] is doing

well, but our family cannot be in public.

(Ryan Murphy)

I've started a database management internship, based

partly on my knowledge I gained through your course…

The 2 Sigma Problem

"The 2 Sigma Problem: The Search for Methods of Group Instruction as Effective as

One-to-One Tutoring." B. Bloom, Educational Researcher (1984).

College is a place where a professor’s lecture

notes go straight to the students’ lecture

notes, without passing through

the brains of either.

—Edwin Emery Slosson

—Plutarch

from Ian Kidd's translation of Essays

The mind is not a vessel that

needs filling, but wood that

needs igniting.
