Kew's  Palm  House is a wonder of the  Victorian age . When it opened in 1848, it was the largest glass house ever constructed. But the hot and  humid  conditions inside that are  essential  for the tropical plants it houses have  taken their toll  on the building. Its  ornate  painted metalwork is  rusting , and 16,000  panes  ...

Use of technology in sports is supposed to be able to provide accurate and instant feedback, with better decision-making and reduced errors compared to human intervention. But is that always the case? 1在体育中使用技术应该能够提供准确，即时的反馈，与人干预相比，决策更好，并且错误减少。 但是总是这样吗？ The annual tennis tournament Wimbledon made the decision this year to replace their line judges....

The logic of common knowledge and social relationships explains why we all deplore the hypocrisy and white lies and role playing of everyday social interaction, but we wouldn't want to live without them. 公共知识与社会关系的逻辑，解释了为什么我们一方面都厌恶日常社交中的虚伪、小谎言以及角色扮演，但另一方面又不愿意没有它们的生活。 As dystopian comedies like "Liar Liar" play out. 就像反乌托邦式喜剧《...

Or laughter, where an unignorable noise can expose the common assumptions among everyone who gets the joke. 或者是笑声，那种无法忽视的声音能够揭示所有明白这个笑话的人之间的共同假设。 Conversely, when we worry about upending a relationship, we might go to great lengths to repress common knowledge. We might avoid looking someone in the eye, or pretend to ignore the elephant in the room or mumble wit...

This can set off cycles of exuberant recursive mentalizing, as investors desperately search for focal points, each one buying an investment not because of its inherent productive value but because they hope to unload it at a profit on future investors, greater fools. 这会引发一种亢奋的递归心理博弈循环——投资者拼命寻找“焦点”，他们买入一种投资并不是因为它本身具有生产价值，而是希望将它高价转手卖给未来...

At larger scales, common salience or focal points and conventions, drive a lot of our legal and financial coordination. An everyday example is driving on the left, or on the right. It doesn't matter as long as everyone agrees to drive on the same side, as in the joke about the woman who calls her husband during his morning commute and says, "Be careful, honey. The radio says that there's a maniac...

When the little boy said the emperor was naked, he wasn't telling them anything they didn't already know. But he added to their knowledge nonetheless. By blurting out what everyone could see within earshot of the others, he ensured that everyone knew that everyone else knew what they knew, that everyone knew that, and so on. And that changed their relationship with the emperor from obsequious defe...

Archaeological evidence indicates that ancient Egypt and Mesopotamia may have been in contact at least 10,000 years ago, when people in Mesopotamia began to farm and domesticate animals, and so making the transition from hunter-gatherers to an agricultural society. Many scholars believe that this social and technological revolution may have influenced similar developments in ancient Egypt, but the...

Surprisingly, severed tissues can survive for a few hours without these resources. And keeping them cool further slows the rate of tissue death, generally giving surgeons a 6-to-12-hour window for reattachment. But once the tissues die, reconnecting them won’t bring them back to life. 令人惊讶的是，断裂的组织即使没有这些资源，也能存活几个小时。而将其保持低温则能进一步减缓组织坏死的速度，通常可以为...

After a long day helping patients in the emergency room, Priya is prepping dinner when her knife slips and neatly severs her finger. Fortunately, being an ER doctor, she knows exactly what to do. 在急诊室忙碌了一整天帮助病人后，普莉娅正在准备晚餐，突然刀子一滑，干净利落地切断了她的手指。幸运的是，作为一名急诊医生，她非常清楚该怎么做。 First, she cleans the wound with a wet paper towel and bandages...

They're not the same, are they? The smiles you see when you meet your friends and family compared with what you see from salespeople trying to get you to buy something or management consultants pretending that the bad news they're giving you is actually good news. How can we tell that someone really means it when they're smiling?1他们不一样，是吗？ 与您从销售人员那里看到的东西相比，您会看到您的朋...

Most of the food on the space station is standard packaged fare, full of goodness, no doubt, but lacking that culinary je ne sais quoi which any self-respecting French astronaut so badly needs. But astronauts can bring with them a certain quantity of their own food. 国际空间站上的大部分食物都是标准的预包装食品，毫无疑问，营养丰富，但是缺少那种让人回味无穷的美食风味，这是任何一位体面的法国宇航员都...

"It opened up something in me that needed to be opened and needed to heal," says Elizabeth Russell, a teacher and librarian from the US state of Connecticut. She was going through a rough patch in life when she found bibliotherapy. Bibliotherapy is the use of literature to support people with mental health and wellbeing issues. The benefits of non-fiction, self-help books are well documented – res...

So a question that I always get asked is: How? How do we integrate different perspectives? Well, it's an art and a science and something that has been explored at length by thinkers from Georg Hegel to Ken Wilber. But for us here today, I'm going to distill it into three questions that I ask myself. Here we go. 我经常被问到的一个问题是：“怎么做？”——我们该如何整合不同的观点？ 这既是一门艺术，也是一...

As am I. I mean, our view will forever be inherently incomplete. But we can always strive to see more faces of the hyper dimensional shape that is reality. Be well. 我也是。我的意思是，我们对世界的看法永远都是不完整的。但我们始终可以努力去看到现实这个超维形体的更多面貌。保重。 So you might think that your way of seeing the world is right, but the three Bills and I are here to suggest that perhaps...

So ... Capitalism. Capitalism is the most powerful prosperity-generating force ever known. 所以……资本主义。资本主义是人类历史上最强大的繁荣创造力量。 Excuse me! Yes. Uh, sorry. I think you mean the most extractive force ever known. 打扰一下！是的，呃，抱歉。我想你是说“最具掠夺性”的力量吧。 Oh, hello. Well, it's lifted billions of people out of poverty and expanded access to food and literacy. It b...

Let me show you what we've built so far. So right off the bat, you can see how this -- it got the the overall aesthetic of the scene, right. You know, everything fits well globally. It got the environment, got the background. It got the pagoda to be the tallest structure. You have these houses next to it and you have the trees behind. So all of that sounds good. 让我给你们看看我们目前构建的成果。...

I'm excited to present a new way to design 3D games with AI. Now, many of you may have used AI to produce text or images or even code, but 3D, with that extra dimension, is incredibly hard. 我很兴奋地向大家展示一种用人工智能设计3D游戏的新方式。现在，你们许多人可能已经用AI来生成文字、图像甚至是代码，但3D，由于它多了一个维度，是非常困难的。 So today, in the next few minutes, you and I are going to c...

What we see here is Vancouver, a combination of tree height data, Landsat vegetation data and information from the affordable housing district, showing the blue dots right now. What we can start to identify is patterns, things that we can see about the city that affect the way that people live in it. You can tell that the areas that have a lot of trees protect us against heat. This is heat data sh...

I'm a digital cartographer by trade, and honestly, the last two, three, four presentations have been incredible. Maps, historically, they do really two things, and we've really seen an amazing amount of the first: understanding our world. But historically, maps weren't just about understanding. They were also about creating, about building, about shaping the built environment around us. They help...

It looks like some kind of underwater ballet: two killer whales rubbing their bodies together as they move through the water. What's trickier to see in this new research footage, that was captured by scientists using drones, is a piece of kelp between the bodies of the two animals. 这种看上去就像某种水下芭蕾舞的动作其实是两只虎鲸在水中移动时一起摩擦着身体。在科学家用无人机拍摄的这段研究画面中，更...

You can't beat a holiday, but would you ever consider going away for just one day? Extreme day trips are a new trend that squeeze international adventure into just 24 hours. It might sound exhausting, but for lots of people, the appeal lies in time efficiency, budget-friendly prices and the excitement of going somewhere and doing something completely new. 没有什么能比得上一场假期，但你有...

Now these are simple things for many businesses to do, but they're very hard for creative people to do. But artist corporations will take these same capabilities and put them in the hands of the entire creative community. And creative people are already leaders and entrepreneurs. We just don't think of them that way. The painter Mike Kelley once said, "I started out an anarchist and a hippie, and...

Eventually I got so frustrated, I started a new project to help creative people release work together. It's called Metalabel. And one of the first releases was by myself and 10 other writers who'd all independently written about the same subject. So I reached out to these people who I didn't know, and I proposed a way that we would work together. We would publish our pieces together in a book, and...

So if you want to understand how challenging the future could be for creative people, just look at what's happening with musicians right now. Up until the late '90s, people either listened to music for free on the radio or by buying a physical copy to listen to at home. But then the internet happened, and now Spotify and other streaming services give us access to an infinite catalog of music. We d...
