「ChatGPT」（チャットジーピーティー）は⽂章⽣成AIです。⼈間が⼊⼒した質問に答える形で⽂章を返してくるので「対話型AI」とも呼ばれています。

ウイルス学者は、ウイルスを作り出すことができます。感染細胞から、ウイルスのタンパク質の設計図が書いてあるDNAをとってきて、それをプラスミドという大腸菌内の環状DNAに入れて増殖させるのです。

In 2021, when the gavel fell at Christie’s on the sale of Mike Winkelmann’s Everydays series—a compilation of 5,000 digital artworks—it made a thunderous announcement: Non-fungible tokens had arrived. The ludicrous world of CryptoKitties and Bored Apes had just produced a piece of art worth $69.3 million (at least according to the highest bidder). On that day, the traditional art market—the largest unregulated market in the world—put its stamp of approval on a very new and carnivalesque digital reality. But what did it mean for these two worlds to collide?

「勝手気まま」に生きるのが、健康寿命を延ばすコツ！60代・70代・80代・90代の心身の変化と過ごし方を、「老い方」の見取り図で分かりやすく解説。

The US healthcare system excels in research, innovation, and clinical care, but is failing to keep up with the operational challenges of the digital age. Today’s healthcare organizations face immense financial challenges, and their most valuable resources - people, rooms, and equipment - are being used inefficiently. The result? Long wait times for patients, overstressed staff, underused assets, and poor ROI for organizations.

Fourteen-year-old Nephele used to have friends. Well, she had a friend. That friend made the adjustment to high school easily, leaving Nephele behind in the process. And as Nephele looks ahead, all she can see is three very lonely years. Nephele is also a whip-smart lover of math and science, so she makes a plan. Step one: invent time travel. Step two: go back in time, have a do-over of ninth grade, crack the code on making friends, and become beloved and popular. Does it work? Sort of. Nephele does travel through time, but not the way she planned - she’s created a time loop.

Nous vivons dans un monde rempli de préjugés. Et cela ne doit rien au hasard. Notre cerveau, fabuleuse machine à appréhender le monde, fabrique sans cesse des stéréotypes et fait de nous, que nous le voulions ou non, de parfaits discriminateurs. Mais, ne vous en faites pas car nous allons vous expliquer pourquoi ce processus est parfaitement normal et comment en limiter les effets néfastes.

American democracy is at risk. Fueled by partisan news and emotion-stoking social media, Americans are becoming less and less able to think rationally about the challenges facing the country. For self-governance to succeed, citizens must analyze issues objectively, engage with one another respectfully, and ground their disagreements in reason and facts. At this precarious moment in our history, we need a renaissance in critical thinking. It can start in the math classroom.

The Cold War seemingly ended in a decisive victory for the West. But now, Noah Feldman argues, we are entering an era of renewed global struggle: the era of Cool War. Just as the Cold War matched the planet’s reigning superpowers in a contest for geopolitical supremacy, so this new age will pit the United States against a rising China in a contest for dominance, alliances, and resources. Already visible in Asia, the conflict will extend to the Middle East (U.S.-backed Israel versus Chinese-backed Iran), Africa, and beyond.

Once you know how to see them, numbers are all around us - buried in the dimensions of buildings and encoding the data on our favourite gadgets. They’re a beautiful system of patterns and codes but also an essential tool that can guide our daily decisions, change our behaviour and even predict the future - if we can just learn how to use them right.

The ACT is a standardized test designed to show colleges how prepared you are for higher education by measuring your reading comprehension, knowledge of writing conventions, and computational skills and then comparing you with the rest of the high schoolers who take it. This ACT prep audio program is designed for busy students like YOU who want step-by-step and affordable guidance for this entrance exam.

Just prior to the end of the previous millennium, Dr. Bread accepted a full-time position to do research at the Los Alamos National Laboratory in New Mexico. While she is prohibited from revealing classified information, Janet Bread can and does describe the evidence of a miscarriage of justice in the nation’s most notorious espionage case from the 1940s. As a compassionate individual with a sense of purpose and loyalty to the truth, she found the callous mistreatment of certain participants in a disinformation project to be deeply disturbing.

Who knew solving math problems could be this much fun? Many kids struggle with math, especially as they move on to more and more abstract concepts. It’s harder to understand an idea when you can’t visualize it and see how it applies to you. By making math concepts more relatable, children may find that math can actually be enjoyable and relevant. With this collection of math riddles and brain teasers, carefully created by Cooper the Pooper, you won’t get the same old math problems that only cover what’s taught in school.

Our universe has multiple origin stories, from religious creation myths to the Big Bang of scientists. But if we leave those behind and start from nothing—no matter, no cosmos, not even empty space—could we create a universe using only math? Irreverent and boundlessly creative, The Big Bang of Numbers invites us to try.
