Today we’re going to talk about confidence intervals. Confidence intervals allow us to quantify our uncertainty, by allowing us to define a range of values for our predictions and assigning a likelihood that something falls within that range. And confidence intervals come up a lot like when you get delivery windows for packages, during elections when pollsters cite margin of errors, and we use them instinctively in everyday decisions. But confidence intervals also demonstrate the tradeoff of accuracy for precision - the greater our confidence, usually the less useful our range. Crash Course is on Patreon!

For Formula E driver Sam Bird, driving an electric racecar is not just a career, but a passion that could have a positive impact on the environment. Leading-edge technology is vital to fast-forward these changes. Hewlett Packard Enterprise is providing Bird’s DS Virgin Racing Team with innovative IT solutions that will help these electric racecars operate more efficiently, ultimately informing sustainable transportation developments for future generations. As Bird puts it, “Racing is important, not only from a sporting perspective but from a life perspective. This is the catalyst for change.” This Great Big Story is by Hewlett Packard Enterprise: https://www.hpe.com/us/en/home.html SUBSCRIBE: https://goo.gl/vR6Acb Got a story idea for us?

I consider myself rather good at resisting a smooth tongued salesperson but on a warm day in India s northern state of Himachal Pradesh I met my match. These two young girls hustled me and hustled me good. Watch how they did it.

I have seen some strange things on my travels in India but nothing as mysterious as this bridge. Located in an empty Indus river valley in the Himalayas I came across it by chance and am still perplexed as to what it was all about. Was it cursed with some kind of voodoo magic or is there a simpler explanation? Would you dare cross it?

Adoringly known as “red gold,” paprika is the undisputed spice of Hungary. The 200-year love affair started when, seeking an alternative to expensive black pepper, people in the Szeged region of the country began grinding a readily available red pepper fruit into a delightfully hued seasoning. Today, it’s become a cultural touchstone, with museums and festivals dedicated to the spicy stuff, and new generations of top chefs securing its place in premium gastronomy.

It can be deeply painful to be the child of snobs. That is, to be someone who received a kind of love in our formative years that was heavily dependent on our performance, not on our essence. It can be enough to make a mess of our lives, unless we realise - and get on top of - the dynamics.

They are the people in the newspaper, or the ones who live in the other part of town or went to the school we didn’t go to – but it’s nice not to imagine them too near to home. Yet that’s to deny an obvious eventuality: snobs may lie closer to us. Snobs form couples; they have children. And we might be among them. However painful the unvarnished thought, we might be the children of snobs. It’s a situation it can be therapeutic to face up to and to try to make sense of…” You can read more on this and other subjects on our blog, here: https://goo.gl/cgQRoM MORE SCHOOL OF LIFE Visit us in person at our London HQ: https://goo.gl/PDrC4Z Watch more films on WORK and CAPITALISM in our playlist: http://bit.ly/TSOLcapitalism You can submit translations and transcripts on all of our videos here: https://www.youtube.com/timedtext_cs_panel?c=UC7IcJI8PUf5Z3zKxnZvTBog&tab=2 Find out how more here: https://support.google.com/youtube/answer/6054623?hl=en-GB SOCIAL MEDIA Feel free to follow us at the links below: am8qWH Facebook: https://www.facebook.com/theschooloflifelondon/ Twitter: https://twitter.com/TheSchoolOfLife Instagram: https://www.instagram.com/theschooloflifelondon/ CREDITS Produced in collaboration with: Kate Balchin http://www.katebalchin.com/ #TheSchoolOfLife

I m a huge fan of Filipino food. Street food in the Philippines is some of my favourite because a lot of it is so different interesting, and tasty. As a foreigner in the Philippines...Why go to a Filipino restaurant when you can get delicious Pinoy street food, and be eating Balut, Isaw, and other strange foods? Manila especially is great for this! Just a few days before getting my Kalinga Tattoo from Whang Od in Buscalan we visited an Igorot village elder to get his permission to visit his ancestors at a hanging coffin site in Sagada. He was smoking a very important type of Igorot food called Etag. Etag is used in ceremonies in this part of the Philippines, I was interested in trying it because the traditional way of preserving it, invited maggots, beatles and all other sorts of insects into the process. I m so happy I was able to spend such quality time with Lakay Wa-Ow, try on his ceremonial necklace, and also buy his Etag. I m excited to share the second part at Amir s Birthday Party. Stay tuned! Inspired by the Best ever food review show and their various interesting Filipino travel vlogs about foods like Catching and eating Wild Tamilok in Palawan.... Is this Philippines Strangest or Scariest Food? Where are my Filipino and Filipina subscribers at!?

In fantasy stories, charlatans in fancy robes promise to turn lead into gold. But real alchemists weren’t just mystical misers. They were skilled experimentalists, backed by theories of matter.

We started “travel hacking” and taking more trips together and finally decided we wanted to travel for one year. After 2 years of saving $ and travel hacking over 2 million miles and points, we sold our cars and apartment and left home January 10, 2016. We started this YouTube channel to share our experiences with friends and family, then decided we really liked vlogging and traveling. So we extended our 1 year trip to THREE years :) Now we have a goal of traveling to 100 countries before Nate turns 30 (which is March 20, 2019)! We are incredibly thankful to do something we love every day. :)
