今天我们来聊一个神秘的女人。从1970年开始到现在，50多年过去了。哪怕动用了国家情报机构的力量，哪怕是一个又一个科学团队，使用最先进的同位素分析，和DNA技术，到现在依然没有任何人知道她的真实身份。她只有一个代号：“伊斯达尔女人” 挪威拥有美丽的海峡, 气势磅礴的冰川，还有森林覆盖的山脉，所以这里是世界上最好的徒步旅行地之一。想想看，不用花一分钱，简单的就这样走进大自然，让自己沉浸在美丽的大自然中，暂时远离着生活中的一切的琐碎，这是多少便宜的幸福啊。所以建议大家也可以试一试。但是也请大家做好心理准备，远足并不一定都会看到美好的事物。 1970年11月29日，一个父亲带着两个女儿，在挪威卑尔根市附近的伊斯达伦山谷远足。然而其中一个小女儿则在一圈石头的中间，发现了一具烧的焦黑的尸体。 她的两臂在空中呈现出类似，拳击手的姿势，好像在抵御一个看不见的攻击者。后来法医说，这其实很常见，很多烧焦的尸体都会出现这样的姿势。 她面部焦黑，完全没有辨识度。甚至她看起来都有点不像人类了。当天晚上，这一家三口立刻向警方报告了他们的发现。于是调查立即展开，当时的人谁都没想到，他们正参与现代历史上最大的谜团之一。 长达数十年的探索才刚刚开始。 接着警方来到现场，发现了很多奇怪的地方。首先，她身体的正面，包括她的脸，被烧得面目全非，但是她的背面却没有烧焦。 另外在尸体的周围，发现了几件珠宝，一把破伞，一袋包好的午餐，一个火柴盒，一个空酒瓶，手表，尼龙丝袜的残留物，另外还有一双橡胶靴。等等 。 对于一个在山里徒步的女人来说 ，这些东西大部分听起来都是相当的正常。但是有趣的是，这些物品的发现的地方却很奇怪。 她既没有穿戴它们 ，也没有拿着它们 ，它们好像是被故意整整齐齐地排列在她的身体周围 ，就好像是某种奇怪的仪式一样。 另外还有一点很奇怪，她所有的物品，都被完好无损的排列在周围，身上一丝不挂，然而警方却发现，她却把那最重要的，证明他身份的护照故意烧掉了。 而且除此之外，还有一点非常奇怪。他衣服上的所有识别标签，已经被剪掉。包括尸体旁边的空酒瓶，上面的标签也被故意的撕掉。就像是她在故意隐藏自己的身份一样。 成为此频道的会员即可获享以下福利： https://www.youtube.com/channel/UCfkFEfvGzuMT4hK0suu_Q2g/join

Is chemistry truly everywhere? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer fan questions about chemistry with Kate Biberdorf, aka Kate the Chemist. Discover the chemical reactions that make our world work! What is fire? We break down combustion reactions and how– scientifically– dragons could breathe fire, if they existed, that is. We discuss Kate the Chemist’s fiction series as well as her new book for adults, It s Elemental: The Hidden Chemistry of Everything (https://amzn.to/3edaA3o). Dive into the periodic table through the eyes of a chemist and an astrophysicist. Astrochemistry anyone? We discuss where we can find lithium on Earth and why not all the iron is in Earth’s core. Did some iron get distracted? Why did many scholars practice alchemy? Was it just in the pure pursuit of science? Learn some fun chemistry experiments you can do at home. What is stoichiometry? What is catalysis? You’ll learn about functional groups and how an element’s state impacts its reactions. Why don’t we power cars using hydrogen? Find out about salt ionization and how salt water works. Does cooking food change its chemistry? What is caramelization? Are we on the cusp of discovering a new branch of chemistry? How does an atom work? As a society, have we reached a scientific plateau? We also discuss if there is a chemical solution to combating climate change? All that, plus, what element did astrophysicists discover on the sun before we discovered it on Earth? The answer might surprise you.

North America is preparing itself for the August Eclipse, so we thought it would be a good time to explain how eclipses work and what’s going on as the Moon briefly destroys the Sun.

Briefly. But don’t worry, the Sun will return. For the first time since 1991, the United States will experience a total solar eclipse. In fact, everyone in North America will get a chance to see some version of this epic event - 500 million people will see the Sun dim to some extent. But for the fortunate people on an epic path from Lincoln City on the Oregon Coast, to Charleston, South Carolina, they’ll see one of the most dramatic and awe inspiring events of the sky. If you’re one of the people along that path, and you’ve got the proper eye protection - make sure you’re wearing proper eye protection - you’ll see a bite appear on the side of the Sun. Over the course of over an hour, you’ll see more and more of the Sun disappear, blocked by the Moon. At the halfway point, the last remnants of the Sun will be completely covered, casting the area in darkness. The Sun’s mysterious corona will appear as a ghostly halo around the Moon, and the stars will come out. For a few brief minutes, you’ll experience totality. And that’s when the eldar Lovecraftian gods will come pouring forth from this eldritch rift in spacetime, to consume our planet in madness. Or, you know, maybe not, the ancient scrolls are unclear. What is clear is that the Sun will return, slowly but surely. Then there’ll be traffic jams as a huge population returns home, spiritually awakened by this momentous event. Will you be there? I will. But what’s going on? What are the underlying geometries that create such a spectacular moment for us to witness? Eclipses are caused because of the orbital alignments of the Earth, Sun and Moon. The Earth travels around the Sun, and the Moon travels around the Earth. When the Moon is in the Earth’s shadow, that’s a lunar eclipse, and when the Moon’s shadow falls on the Earth, that’s a solar eclipse. The Earth orbits the Sun at an average distance of about 150 million kilometers, and the Moon orbits the Earth at a distance of about 385,000 kilometers. But in one of the craziest coincidences, the size of the Moon and the size of the Sun are almost exactly the same from our perspective. The Sun is 400 times bigger than the Moon, but it also happens to be 400 times farther away. The Moon is slowly drifting away from the Earth, so in a few billion years, this will no longer be the case. The Moon will no longer be big enough in the sky to perfectly cover the Sun. We don’t get eclipses every month because the orbits of the Earth and Moon are slightly inclined from each other. Sometimes the Moon passes above the Sun, other times it passes below. From the Earth’s perspective, you’ll see the Moon chomp away and block the Sun. But seen from space, you’ll see a better idea of what’s going on. The Moon casts a shadow down onto the surface of the Earth. For the 2017 eclipse, the shadow appears out in the Pacific ocean, and then races across the surface of the planet. For anyone actually caught in the shadow, they’re able to see the complete eclipse, where the Moon fully blocks the Sun. For everyone else on either side of the shadow, you see a partial eclipse, where only a chunk of the Sun is blocked by the Moon. Every year, there are usually a couple of total solar eclipses, visible from somewhere on the planet, and there are larger chunks that can see a partial eclipse. The Earth follows an elliptical path around the Sun, and the Moon makes its own elliptical path around the Earth. So the size of both the Sun and the Moon can be slightly different sizes in the sky. When the Sun is at its largest, and the Moon is at its smallest, that’s an annular eclipse. The Moon doesn’t completely cover the Sun and create the special event of a total eclipse.

World s Most Dangerous Roads: Deadliest Journeys in Benin in 2016 Deadliest Roads - Vietnam: https://youtu.be/o62sk4600m8 In the far north of Benin, in the heart of an arid jungle, the Baribas people make their home. Historically warriors, they have now become farmers and gain their wealth principally from the cotton market. For months, the cotton trucks move to the rhythm of the inhabitants of North Benin. Dramane and Zachari maintain the traffic from the North to the South of the country, on track or pavement, in spite of the danger. On board trucks that they have named “Titans,” or aboard battered vans, they sidle along uneven roads, at the risk of toppling over at any moment due to the several tons of cargo that weigh down their vehicles. Dramane has 24 hours to cross the country with his foot firmly on the gas, trying to reach the Cotonou harbor. Cotonou, rather than being a reference to cotton, signifies ‘The River of Death,” which is an apt term for the route that he is traveling… ▬▬▬▬▬▬▬▬▬ Subscribe Free Documentary Channel for free: https://bit.ly/2YJ4XzQ Join the club and become a Free Documentary Patron: https://www.patreon.com/freedocumentary Facebook: https://bit.ly/2QfRxbG Twitter: https://bit.ly/2QlwRiI ▬▬▬▬▬▬▬▬▬ #FreeDocumentary #Documentary #MostDangerousRoads ▬▬▬▬▬▬▬▬▬ Free Documentary is dedicated to bringing high-class documentaries to you on YouTube for free.
