Today's Google Doodle celebrates Teachers Day in India. Doodler Olivia Huynh has captured the relationship between an eager student and the teacher through a series of math puzzles.

Referring to a quote by Confucius, Google adds, 'A true teacher is one who, keeping the past alive, is also able to understand the present.'

It further adds, 'Teachers are our mentors, friends, and catalysts. They're the wild, eager sparks that can, with a word, set our passions ablaze. Not quite parents, they nevertheless raise us to be the very best versions of ourselves. And their impressions last lifetimes, as the lessons we've learned are passed down to others, like inheritances of wisdom. Today, let's celebrate teachers, one of the noblest and most selfless of callings, all across India.'

Google also added an early sketch and animation of the Doodle. Seems like Google just used the earlier serif version of the older Google logo instead of the new Google logo it unveiled a few days ago..
