Everyone knows Newton's apple tree which he found gravity.
But I didn't know where the tree is and whether it still is or not.
Then I found that the apple tree is in Cambridge when I searched
where to go in the city.
The tree is at front of Trinity college.
Many colleges are opened for tourists,
but the college is closed.
This is the Newton's apple tree I'd wanted to see.
Google map and a board pointed the tree is that one
but I can't say that surely.
Is this a apple tree.
While I was writing the posting.
Sadly the tree is not the original one.
I should have searched more about the tree.
