from the world's big
Khan Academy founder Salman Khan explains how always dreaming big and setting audacious goals got him to where he is today.
Salman Khan is an American educator and founder of the Khan Academy, a free online education platform and not-for-profit organization. He has produced over 2200 popular videos elucidating a wide spectrum of concepts, mainly focusing on mathematics and the sciences, in his home. His official channel, 'Khan Academy' has, as of March 2011, attracted more than 45 million views.
Set audacious goals
Salman Khan: In the early stages of Khan Academy, the passion and the ability to just execute directly were super important. Because my background was in software I didn't have to kind of get other people or get funding to start building prototypes. And sometimes I get obsessed with things and it allowed me to create just a ton of content and give it a critical scale so that it could be useful. It has a critical breath.
As Khan Academy then grew and became — more people knew about it, I think it was important — and I attribute a lot to just reading science fiction books and thinking on larger scales in the next four years or 10 years or even my lifetime — is, what could this be? If we're really allowed to dream, what could this be? It feels like we're at an inflection point in history. And when you're at these inflection points, there's new opportunities and there's new problems, but it's often the case that you can take advantage of the new opportunities, the technological opportunities, to solve the new problems.
And I had this lens of, well, maybe this Khan Academy thing instead of it just being a one-off collection of videos or a one-off software app that I tried to do as a venture-backed business, maybe this could be the next Stanford, the next Harvard, this new type of institution that people haven't visualized quite yet, but it could help empower millions or billions of students for the next 500 years. And as soon as you start thinking on those scales, you go after a bigger problem and you phrase things differently and, frankly, you inspire more people. More amazing people are going to want to be part of that audacious goal.
And I think because Khan Academy didn't aspire to just to be a business, so to speak, we have been able to attract some of the very best talent around the planet for this mission. And so I think that's kind of the — you know, execute, build something, make it real, articulate a big bold vision, but one that people can believe that is possible because of the traction that you've just had, and then leverage those pieces to get just the best people around you that you can. And I think if you're able to pull that off, then you're off to the races.
In this Big Think Edge preview, Khan Academy founder Salman Khan explains how always dreaming big and setting audacious goals got him to where he is today. Ambition gets other people excited in your ideas. That's why it's vital to always keep reaching for the stars.
Andy Samberg and Cristin Milioti get stuck in an infinite wedding time loop.
- Two wedding guests discover they're trapped in an infinite time loop, waking up in Palm Springs over and over and over.
- As the reality of their situation sets in, Nyles and Sarah decide to enjoy the repetitive awakenings.
- The film is perfectly timed for a world sheltering at home during a pandemic.
A recent analysis of a 76-million-year-old Centrosaurus apertus fibula confirmed that dinosaurs suffered from cancer, too.
- The fibula was originally discovered in 1989, though at the time scientists believed the damaged bone had been fractured.
- After reanalyzing the bone, and comparing it with fibulas from a human and another dinosaur, a team of scientists confirmed that the dinosaur suffered from the bone cancer osteosarcoma.
- The study shows how modern techniques can help scientists learn about the ancient origins of diseases.
Centrosaurus apertus fibula
Royal Ontario Museum<p>In the recent study, the team used a combination of techniques to analyze the fibula, including taking CT scans, casting the bone and studying thin slices of it under a microscope. The analysis suggested that the dinosaur likely suffered from osteosarcoma, a type of bone cancer that affects modern humans, typically young adults.</p><p>For further evidence, the team compared the damaged fibula to a healthy fibula from a dinosaur of the same species, and also to a fibula that belonged to a 19-year-old human who suffered from osteosarcoma. Both comparisons supported the osteosarcoma diagnosis.</p>
Evans et al.<p style="margin-left: 20px;">"The shin bone shows aggressive cancer at an advanced stage," Evans said in a <a href="https://www.rom.on.ca/en/about-us/newsroom/press-releases/rare-malignant-cancer-diagnosed-in-a-dinosaur" target="_blank">press release</a>. "The cancer would have had crippling effects on the individual and made it very vulnerable to the formidable tyrannosaur predators of the time."</p><p style="margin-left: 20px;">"The fact that this plant-eating dinosaur lived in a large, protective herd may have allowed it to survive longer than it normally would have with such a devastating disease."</p><p>The fossilized fibula was originally unearthed in a bonebed alongside the remains of dozens of other <em>Centrosaurus </em><em>apertus</em>, suggesting the dinosaur didn't die from cancer, but from a flood that swept it away with its herd.</p>

It also shows that dinosaurs suffered through some of the same terrestrial afflictions humans face today.</p><p style="margin-left: 20px;">"Dinosaurs can seem like mythical creatures, but they were living, breathing animals that suffered through horrible injuries and diseases," Evans said, "and this discovery certainly makes them more real and helps bring them to life in that respect."</p>
