Across millennia, cultures and civilizations have envisioned the ability to revisit the past, glimpse the future, or even rewrite fate. From ancient mythologies to modern science fiction epics, the allure of time travel persists as one of humanity’s most profound and enduring fascinations.

The internet has transformed our world in amazing ways. With just a few clicks, we can talk to friends on the other side of the globe, discover new music, explore our favorite hobbies, shop for just about anything, and even take entire college courses from the comfort of our couch. It’s no exaggeration to say that the internet is one of the greatest tools ever invented. But just like in the real world, not everyone you meet online has good intentions. Hidden among the games, chats, and cute cat videos are people who spend their time trying to trick others.

The world we live in presents itself as orderly, predictable, and governed by consistent rules—gravity pulls downward, the sun rises in the east, and time moves steadily forward. Our daily experience, guided by logic, memory, and sensory feedback, creates a sense of permanence and coherence that we seldom stop to question. We trust in this continuity because it is the foundation upon which our understanding of reality is built. But what happens when, for the briefest of moments, reality falters?

Our lungs are amazing organs! In fact, they’re some of the hardest-working parts of our bodies. Every moment of every day, our lungs draw in air, extract the oxygen we need to survive, and expel carbon dioxide, the waste product we don’t need. This exchange happens quietly in the background, without us even noticing most of the time. Whether we’re awake, asleep, walking, laughing, or simply sitting still, our lungs are constantly doing their job—keeping us alive and energized. Breathing is one of those things we take for granted—until something goes wrong.

Struggling to get a good night’s sleep? You’re not alone. Millions of people around the world wrestle with the same challenge—tossing and turning through the night, waking up groggy, and stumbling through their days in a fog of exhaustion. In our fast-paced, high-stress, and constantly connected world, restful sleep can feel like a luxury instead of the necessity that it truly is.

It’s thrilling… and overwhelming. But here's the good news: you're not powerless. You’re far more adaptable than you think. In The AI Future & You, psychologist and human resilience expert Dr. Robert Puff offers a deeply human roadmap for navigating this era of seismic change—not by resisting the wave, but by learning to ride it.

Micro-habits are exactly what they sound like: tiny, easily achievable actions that require little time or effort but, when repeated consistently, can lead to profound changes over time. Think of brushing your teeth while balancing on one leg to improve stability.

Quantum physics is the cornerstone of our world, offering a framework so expansive and precise that it underpins nearly every piece of modern technology. Yet, at the same time, it’s one of the hardest subjects to grasp. In Why Nobody Understands Quantum Physics, a leading scientist and a literary mind unite to explain the revolutionary discoveries and astounding phenomena at the heart of quantum physics. From the greenness of grass to the solidity of matter, they unravel why the universe behaves in the peculiar ways it does and why it's so important.

Cats. Those elegant, elusive, and often hilariously dramatic creatures that slink through our lives with an effortless grace. Whether they’re stretched out in a sunny patch on the floor, perched atop your refrigerator for no apparent reason, or staring at an invisible ghost in the corner of the room, cats never fail to be captivating, confounding, and completely in control of their domain. If you live with a cat, you know they’re never just “there.” They’re assessing, planning, communicating—in ways that are often too subtle or too strange for most of us to decipher.

Many scientists and doctors believe that there is no such thing as the soul. That there is no part of us that persists beyond death. We are not spiritual in any respect. We are made up of cells and tissue, and completely controlled by a material organ in our heads: the brain. In this groundbreaking book, Dr. Michael Egnor makes the case—based on 40 years of practice and over 7,000 brain surgeries—that science has gotten it all wrong.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

Nearly everyone is familiar with holograms - three-dimensional images projected into space with the aid of a laser. Two of the world's most eminent thinkers believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. University of London physicist David Bohm, one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, an architect of our modern understanding of the brain, have developed a remarkable new way of looking at the universe.
