an Internet Treasure is a service on the Internet that is wide open, gets better when more people use it, and solves a need that many/all of us have。

物理学家确定吹出大泡泡的最优泡泡液配方
无论年龄多大，人人都爱吹泡泡，越大越好。但要吹出创纪录的大泡泡需要非常精确的泡泡液。根据发表在《Physical Review Fluids》期刊上的一篇论文，物理学家确定了混合不同链长聚合物的关键成分，它吹出的肥皂薄膜能伸展到足够薄，形成巨大的但不会破裂的泡泡。论文合作者、Emory 大学物理学家 Justin Burton 是在巴塞罗那出席会议期间看到街头表演者吹出巨大的泡泡而对此产生了兴趣。他的团队发现，聚合物链是产生巨大泡泡的关键，而不同长度的聚合物链比单一长度的聚合物链能形成更结实的肥皂薄膜。他们公布的配方包括：1 升水，50 毫升专业洗涤剂，2 到 3 克的瓜尔胶粉，50 毫升外用酒精，2 克发酵粉。Media

为什么学习历史是很重要的？
John Lilly: You also are known for reading a lot of history (including physical books), why do you think it's important to study history?
Patrick Collison: It’s a way to cheat. You could try to pound your head against the wall and think of original ideas — or you can cheat by reading them in books.

“We NO the Future.
本篇的副标题，起的有些暧昧。作者可能取了No和Know的谐音，于是这个副标题，就又被赋予了双关。
“我们知道未来”
“我们没有未来”

When you bought your first smartphone, did you know you would spend more than 1,000 hours a year looking at it?
Months later, can you remember how you spent those hours?
When you upgraded to a new smartphone, so you could spend more hours on it, did you think about how you had spent so much of your ‘free’ time the year before?
If we wasted money the way we waste time, we’d all be bankrupt.
