We’re Not Playing The Algorithm Game (And We Need Your Help)

You can help us reach more learners! https://complexly.info/CCcoin26-18 The 2026 Crash Course Coin is here! Each year we release limited-release coins that allow you to help us reach thousands of learners. For example, every hundred dollar coin helps us reach 2,000 learners. And every $500 coin helps us reach 10,000 learners. We’re also offering coins that help us reach 20,000, 100,000, and (for the first time ever) 200,000 learners! This year, the coin is inspired by our goal to be a signal in the noise. It shows a sound wave that, for us, represents our commitment to offering clarity, context, and meaning. And actually, features the sound wave of the words “knowledge weighs nothing,” which is part of a phrase we’ve printed on every Crash Course coin to date. “Knowledge weighs nothing: carry all you can.” These beautiful objects are minted in Arkansas from hand-engraved dies at Shire Post Mint. And they are only available for a limited time! Learn more about the coin and how to get one at https://complexly.info/CCcoin26-18 People like you make it possible for Crash Course to keep providing high-quality educational material that’s accessible and free.

Sovereign Citizen KAREN Skipped Her JURY TRIAL And Now She Is Paying For It With Her FREEDOM!

Hey guys, and welcome to today's video! Today, we have 2 Sovereign Citizen Karens in court! The first is a follow up to a Karen who got thrown out of court for her disruptive behavior. She's been arrested again, and is now in custody! Then we have a follow up to a sovereign citizen Karen I've covered previously, who thinks the court doesn't have jurisdiction over her, so she skipped her jury trial! So the police went to her home and arrested her, ensuring she makes it to her next court date! This is a great of example of what happens to you when you mix being pro se with sovereign citizen nonsense!

Why is getting bitten by a rabid animal so dangerous? - Charles Rupprecht

Take a look at what makes rabies the most lethal infectious disease, and what measures you should take if you're exposed to it. -- In 1885, Joseph Meister was bit in 14 places by a rabid dog. His mother rushed him to Paris for an experimental vaccine from Louis Pasteur, and he became the first rabies-vaccinated person to survive. Today, without proper intervention, rabies remains deadly in almost all cases. So, what makes it so dangerous to humans? Charles Rupprecht explores what makes this infectious disease so lethal. Lesson by Charles Rupprecht, directed by Anton Bogaty.

Sea Stars Use an Army of Tube Feet to Find Their Next Meal | #DeepLook #Shorts

They may look cute and colorful, but starfish are actually voracious predators. To sniff out and capture their prey, they rely on hundreds of water-propelled tube feet, each with a fiercely independent streak.

Who’s That Noisy Segment #3. Your Questions and E-mails Question #1: Lots of AI Consciousness Feedback Segment #4. Science or Fiction Each week our host will come up with three science news items or facts, two genuine, one fictitious. He will challenge our panel of skeptics to sniff out the fake – and you can play along. Theme: Ancient Medicine Item 1: The earliest direct evidence for suturing of wounds dates back 12,000 years in Gobekli Tepe in the region of modern-day Turkey. Item 2: Scientists have reported evidence for a successful surgical amputation of a lower limb 31,000 years ago, with the individual surviving at least 6-9 years afterward. Item 3: As early as 1,000 BCE, Indian and other ancient cultures used ant jaws as surgical staples to close wounds, allowing live ants to bite the wound edges. Segment #5. Skeptical Quote of the Week “Nothing more strikingly betrays the credulity of mankind than medicine. Quackery is a thing universal, and universally successful. In this case it becomes literally true that no imposition is too great for the credulity of men.” - Henry David Thoreau
