Choose one: (A) Science gives us objective knowledge of an independently existing reality.... or (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world.Made your choice? Welcome to the science wars. This long-running battle over the status of scientific knowledge began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has reemerged in today's conflict between science and religion over issues like evolution.

Scientists put things into groups so they are easier to study. Materials have different properties. What are they, and how they are grouped? Let’s investigate materials!

The prospect of living to 200 years old isn’t science fiction anymore. A leader in the emerging field of longevity offers his perspective on what cutting-edge breakthroughs are on the horizon, as well as the practical steps we can take now to live healthily to 100 and beyond.

One of the greatest scientific feats of our era is the astonishing progress made in understanding biology-the intricate machinery of life-a progress to which the period we are living in right now has contributed the most.As you read these words, researchers are delving ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative products that are already changing the world.

In this fascinating 36-lecture exploration of scientific growth filled with ideas, anecdotes, and insights. You'll see how 20th-century scientists have built on crucial 19th-century concepts such as energy, natural selection, atoms, fields, and waves to assemble a body of knowledge to stun even the most farsighted scientific thinkers of that not-too-distant past.

Books are made with paper. But what if we tried to make a book with metal? Copper, tin, gold, silver—would any of those materials work to make a book? Find out more about metal, its properties, and how it is produced. Then decide if you really could make a book out of metal.

In this podcast, Taylor and Andrew investigate the past, present, and future of materials science and engineering. Topic areas ranging from cutting edge materials technology, the history of different materials, the commercialization of new materials, and exciting advances in processing and characterization are all covered in detail. Our episodes include things like the unlikely discovery of superglue or teflon, the fascinating backstories about modern biomaterials like dialysis filters, and updates on new technologies including wearable electronics, next generation batteries, and nanomaterials...

Ernest Rutherford, who grew up in colonial New Zealand and came to Cambridge on a scholarship, made numerous revolutionary discoveries, among them the orbital structure of the atom and the concept of the “half-life” of radioactive materials, which led to a massive re-evaluation of the age of the Earth―previously judged just 100 million years old. Above all, perhaps, Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces―forces, as Rutherford himself predicted, that would bring us the atomic bomb.

In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions - clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips - and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer.

In February 1971, as Apollo 14 astronaut Edgar Mitchell hurtled Earthward through space, he was engulfed by a profound sense of universal connectedness. He intuitively sensed that his presence and that of the planet in the window were all part of a deliberate, universal process, and that the glittering cosmos itself was, in some way, conscious. The experience was so overwhelming, Mitchell knew his life would never be the same.
