As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they’re really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors, conductors, electric field lines, and how objects with net charge generate electric fields.
Electric Charge: Crash Course Physics #25
Moving on to our unit on the Physics of Electricity, it’s time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean? In this episode, Shini talks about electrostatic forces, electrical charge, Coulomb’s law, and the force between charged particles.
Muon experiment: Did scientists just discover a new force of nature? | DW News
Physicists are excited and say this could be a major breakthrough in our understanding of the universe. It all has to do with the behavior of sub-atomic particles called muons. Experiments at a lab near the US city of Chicago have shown that muons move at a rate that’s faster than expected – potentially unlocking the secrets of a previously undiscovered fifth force of nature.
Electricity: Crash Course History of Science #27
The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.
NFTs Are Fueling a Boom in Digital Art. Here’s How They Work | WSJ
Non-fungible tokens, or NFTs, have exploded onto the digital art scene this past year. Proponents say they are a way to make digital assets scarce, and therefore more valuable. WSJ explains how they work, and why skeptics question whether they’re built to last.
Billionaire Winklevoss Twins Talk The End Facebook, Bitcoin, And NFTs | Forbes
Tyler and Cameron Winklevoss didn’t grow up underdogs. But after losing an epic battle with Mark Zuckerberg over ownership of Facebook and being shunned in Silicon Valley, Cameron and Tyler Winklevoss are back—this time as budding Bitcoin billionaires at the center of the future of money, the creative economy and quite possibly a new operating model for Big Tech itself.
The 39-year-old brothers’ hottest venture, digital art auction platform Nifty Gateway, is basking in the glow of a sale at Christie’s, where the gavel is about to fall on the 255-year-old auction house’s first-ever sale of a nonfungible token (NFT) artwork, a one-of-a-kind computer file tracked on a digital ledger known as a blockchain. Nifty Gateway put the artist, Mike Winkelmann, who goes by Beeple, on the map through a series of “drops” starting last year. Before the day ends, Gemini’s custodial business, which houses digital assets securely, will receive a $69 million cryptocurrency payment for Beeple on behalf of Christie’s, making his “Everydays: The First 5,000 Days” the third-most-expensive work sold by a living artist, after Jeff Koons and David Hockney.
Much of the world still thinks of the 6-foot-5 twins as the crew-rowing chumps played by Armie Hammer in The Social Network, the hit 2010 movie about Facebook. At Harvard, classmate Mark Zuckerberg had swiped their idea for a social networking site, building an empire with 2.8 billion worldwide users and a personal fortune now worth $97 billion. A dozen years after they settled with Zuckerberg for $65 million in Facebook stock and cash, the Winklevii, as they are widely known, have emerged as leaders of a technological movement whose core operating principle involves digitizing the records of all assets globally, decentralizing control and cutting out gatekeepers—including Facebook.
The Winklevii say they’re just getting started. Through their holding company, Gemini Space Station, which owns their crypto exchange and Nifty Gateway, and via investments made by their family office, Winklevoss Capital, the duo have invested in no fewer than 25 digital asset startups. These fledgling companies are laying the foundation for what the brothers hope will be a new virtual world that they and others call the “metaverse,” in which digital assets like art, music, real estate and even entire businesses are created, bought and sold—and, most importantly, governed—by the blockchain. Many of the companies they’re backing are positioned to thrive in this three-dimensional version of the internet ruled via peer-to-peer computer networks, where participants rather than powerful companies profit.
“The idea of a centralized social network is just not going to exist five or 10 years in the future,” Tyler predicts when asked about Facebook. “There’s a membrane or a chasm between the old world and this new crypto-native universe. And we’re the conduit helping people transcend the offline into the online.”
What is Tokenomics Explained | Tokenomics 101: Everything You Need To Know
Nowadays, a lot of projects are popping up within the blockchain industry, claiming to be the next big innovation that will change the world. In reality, only a minority is really disruptive. Because of the innovative character of this technology, the number of used cases is unlimited: tracking ownership, the provenance of documents, supply chain management, insurance, and so on. In this video, I’ll introduce you to an important concept of tokenomics, or token economics. This new paradigm is shaking the traditional economy, but it includes many challenges. I’ll underline its key concepts, and its main pain points to keep in mind during the creation of a new token ecosystem.
IonQ to Become First Publicly-Traded Quantum Computing Company
Peter Chapman, chief executive officer and president at IonQ Inc, discusses his company going public via a special purpose acquisition company deal with dMY Technology Group Inc. that gives the combined entity a pro-forma implied market capitalization of about $2 billion. He also shares how soon quantum computing will become mainstream and what real-life issues it can solve. Chapman speaks to Emily Chang on “Bloomberg Technology.”

Why Tesla’s New Nanotech Battery Will Be Worth Trillions
Elon Musk’s Tesla is not just famous for its electric cars. Tesla also has a huge interest in making innovative batteries to power its vehicles. Right now, most electric cars use lithium-ion batteries like the ones used in phones and laptops. The problem is these batteries take a lot of time to charge, and they don’t last very long.
Now, there’s a solution. Graphene, a nanomaterial that has lots of potential applications, can be used to enhance batteries. With graphene, lithium batteries can charge faster, store more energy, and last much longer.
So, is Tesla working on a nanotech-enhanced graphene battery? Find out in today’s video.
