    We all have different ways to navigate (导航) when lost—whether asking a stranger for help, consulting an old-school map or simply following our nose. But on a bike, the risks are higher. One wrong turn or that you're in a traffic jam with two lanes between your bike and the nearest pavement may ruin your good mood. Although cyclists, of course, managed to navigate before smart phones, cyclists can make two choices: a few stay calm and embrace getting lost, and the rest turn to a navigation app.

    Google Maps added a directions function for cyclists in 2015 in the US and Canada, and two years later across Europe. And while there are dozens of other apps now offering a similar service, Google Maps has the demerits for many, so the app seems to be falling behind expectations.

    As someone with no sense of direction, I knew it wouldn't be easy when I started cycling earlier this year. I appreciated that the app gave me two warnings before I needed to turn off a road, and automatically recalculated my route if I accidentally went off course. But still, it wasn't a smooth process. Google Maps thought I could cut across a double carriageway with no breaks in its barrier, assumed I knew what it meant when it told me to “head west”, and thought nothing of taking me the wrong way down a busy one-way street.

    Cyclists don't just want safety—they want convenience. Londoner Robson Smith regularly cycles between Clap ham and the City of London and would like to see Google Maps calculate routes where his bike is allowed on public transport and more choice of the type of routes he can take. “Google tends to calculate the most common and comfortable cycle routes. It would be better to have an option which included the fastest route, regardless of comfort,” he says.

    For this reason, Robson says he uses the app Cycle Streets instead. It offers a choice of four different route modes, based on the type the user wants, and saves previous routes. It also tells you how many calories a route burns, how many traffic lights you wilt encounter, and how busy it is.

学问和智慧

罗家伦

    ①有人以为学问就是智慧,其实有学问的人,何曾都有智慧?世界上有不少学问渊博的人,可是食古不化,食今亦不化,不知融会贯通,举一不能反三,终身都跳不出书本的圈子,实在说不上智慧二字。这种人西洋便叫做“有学问的笨伯”,在中国便可称为“两脚书橱”或“冬烘先生”。反过来说,有智慧的人也不见得都有很好的学问。有一种人,读书虽然不多,但他对于人情事理,都很通达,凭借经验,运用心得,这样的人,你能说他没有智慧吗?

    ②学问是不能离开智慧的,没有智慧的学问,便是死的学问。有许多人从事研究工作,搜集了很多材料,但往往穷年,找不到问题的中心,得不到任何的结果,纵有结果,亦复无关宏旨——这便是由于没有智慧。而有智慧的人则不然,他纵然研究一个极小的问题,也能探骊得珠,找到核心所在;其问题虽小,而其映射的范围,却往往甚大。譬如孟德尔研究豆子的交配,居然悟出遗传的定律,奠下了遗传学和优生学的基础,就是一个例子。再说进化论的创立者达尔文。在达尔文以前,何曾没有富于学问的生物学家,看见过海边的蚌壳、山中的化石、类人的猩猿、初民的种族?何以不能发现物竞天择、最适者存的天演公例?等达尔文发现以后,赫胥黎慨然叹曰:“这个道理,傻子都应该知道,为什么我以前不知道?”当代的物理学家爱因斯坦,有人称他为牛顿后第一人,他的相对论是科学上一个稀有的创获,但是他自己却对人说:“我的发明其实很简单,只是你们看不见罢了!”他能看见别人所看不见的,便是他的智慧过人之处。

    ③学问固然不能离开智慧,同时智慧也不能离开学问。有学问的人,虽然不一定就有智慧,正和有智慧的人不一定有很深的学问一样,但是智慧却必须以学问做基础,才靠得住。无学问的智慧,只是浮光掠影,瞬起瞬灭的。他好像肥皂泡一样,尽管可以五光十色,但是一触即破。惟有从学问中产生出来的智慧,才不是浮光,而是探照灯,可以透过云层,照射到青空的境地。惟有从学问中锻炼出来的智慧,才不是瞬息幻灭的肥皂泡;他永远像珍珠泉的泉水一般,一串串不断地从水底上涌。也惟有这种有根底的智慧,才最靠得住,最为精澈,最可宝贵。

    ④若把学问譬做建筑材料,那智慧便是建筑师的匠心。有木、有石,甚至有水泥钢筋,决不能成为房子;就是懂得材料力学、结构原理,也只可以造成普通的房子,而决不能造成庄严壮丽的罗马圣彼得或巴黎圣母教堂。这种绝代的美术作品,是要靠艺术家的匠心的。但是材料愈能应手,匠心愈能发挥;构造的原理愈进步,艺术家愈能推陈出新。材料与技术对于作风的影响,整个美术史,尤其建筑史,都可以证明。所以学问与智慧是相辅为用,缺一不可的。我们不但需要学问,而且更需要智慧——需要以智慧去笼罩学问、透视学问、运用学问。(原文有删改)
