卡片机傻拍2018（94）
佳能卡片机SX170 IS试拍。感谢您的指教！只裁剪、压缩，未做其它调整。
拍摄于 2018-07-13 14:34 ~ 14:44 许，天津大学卫津路老校区。
这是一颗成熟的天津大学第二代牛顿苹果，我等了5年，终于等到了红苹果。不久前，它从树上自行落下。
重复实验证明，该苹果的味道：
面、沙、软；
酸，持续的酸味。可以接受的好吃的酸。
树上似乎还有近 30 颗苹果，不知道还能不能收集到“自行落下的红苹果”？

[1] National Trust, Isaac Newton's apple tree
The orchard at Woolsthorpe Manor contains an apple tree with a special place in history. Newton's tree is intertwined with his discovery of the law of gravitation – a story Newton himself told.
In the orchard at Woolsthorpe Manor there is an apple tree which first put down roots around 400 years ago. For at least 240 years it's been known as the 'gravity tree' and shown to visitors as Isaac Newton's apple tree, the tree from which an apple fell and caused him to ask the question: 'Why do apples always fall straight down to the ground?'
He began to think about why everything always fell down - not sideways, or upwards - and came to the conclusion that there must be a power (now we call it a force) that draws them. 'How far would that power extend?', he thought. 'Why not as far as the moon?'.
It’s a bit of a scientific legend but there are many truths in it. Much later in his life, Newton told the story to both William Stukeley and John Conduitt, his biographers, and they recorded it in their writings.

[8] HindustanTimes, 2018-07-15, Newton’s apple tree, that inspired the theory of gravity, may find root in India
People have tried growing apple trees far and wide from the temperate, shady garden in Newton’s home in Lincolnshire, England. One such effort was made in India in 1997 by the director of Inter-University Centre for Astronomy and Astrophysics in Pune.
