     Petitionary Prayer

    I was raised in a culture of petition, inculcated from an early age with a repertoire of formulaic prayers addressed to God, his angels, or his saints. All of the prayers assumed a response: Here I am, Lord, deserving of your attention, favor, heating, forgiveness. Never did it pass my mind that my prayers were not heard. My education was hemmed about with a huge body of stories affirming God's intervention in human affairs. Had not every religious person experienced firsthand the power of pr...

     Energy from the Sun to Earth

    It is a feature of the way the world is made that two protons together have less mass than two protons separately. This is a startling but indisputable fact. Weigh two protons separately, then weigh them together: the numbers don't match. The numbers differ by about 1 percent. This curious difference is not to be explained by some law of nature; it is a law of nature, as basic to the way the world works as any fact in our possession. The mass discrepancy is equivalent to an amount of energy g...

     The Matter / Antimater Imbalance in the Universe

    Physicists have long pondered the problem and may have an answer. It seems that just before the universe was one millisecond old, matter and antimatter annihilated each other in a sweeping extinction. But a tiny asymmetry was built into the universe so that matter dominated over antimatter by one part out of 100 billion. Why the built-in asymmetry? In the first 100 billion-billion-billionth of a second of the universe's history, particles called X particles and their antiparticles were create...

     Humans Are Shmoo's to Bacteria

    Remember the shmoo? The shmoo w^as invented by Al Capp in the comic strip "Li'l Abner": a wobbly, tenpin-with legs sort of creature with the misfortune (or good fortune) of being almost totally consumable. Broiled shmoo tasted like steak; fried, like chicken. Shmoos gave eggs, butter, and Grade A milk. The shmoo's skin was a versatile fabric, the eyes made perfect buttons, and even the whiskers served as toothpicks. Most important, shmoos reproduced in prodigious numbers and delivered themsel...

     Why Plants Evolved to be Green

    why is green the dominant color of terrerestrial plants? That's easy. Chlorophyll molecules absorb light at the red and blue ends of the spectrum. It is the middle of the spectrum (the green part) that is reflected and gives plants their characteristic color. A more efficient photosynthetic pigment would be black, absorbing all colors, soaking up all the energy of sunlight, reflecting nothing. The reflected green light of plants is wasted energy. So perhaps the real question is. Why isn't gra...

     The Zodiacal Light

    The zodiacal light is caused by sunlight reflecting from meteoric dust that orbits the sun in the plane of the solar system, remnants of the vast nebula of dust and gas out of which the solar system was born more than four billion years ago. Like the planets, this diffuse stream of particles reflects light, although faintly and rarely seen. Moonless nights of winter are the best time to see the zodiacal light. and nowhere better than here, on the Tropic of Cancer, where the plane of the solar...

     Prayer is Silent Observation

    Learning to pray, then as I understand it, is learning to listen with the mind and the heart – making oneself attentive to each exquisite detail of the world. It is a fearsome exhilarating task, best suited to solitude and silence. Such prayers are answered not with miracles tagged with our names, or those of our loved ones, but with beauty and terror. For the prayerful listener, the world becomes the sublime scripture, full of stories of structure and chaos, law and chance, complexificatio...

     The Energy Game in a Dead Moth

    The moth moves across the porch, millimeter by millimeter, a brief stage of a longer journey of energy from the core of the sun to the table of the ants. Protons fuse at the center of the sun, releasing energy. The energy diffuses upward, taking several million years to reach the sun's surface, where it is released as heat and light. The light streaks across ninety-three million miles of space, reaching the Earth eight minutes later, where it falls upon the green leaves of plants. The plants ...

     The Journey of a Fossil

    One hundred million years ago, an ammonoid lived in the sea that then separated India from Asia. It died and fell into limy sediments on the seafloor. These sediments grew deeper and hardened into rock. The shell calcified, becoming part of the rock, though maintaining every detail of its structure. India was on the move, drifting on a slab of the Earth's mobile crust toward Asia. The floor of the intervening sea was forced under the Asian continent, back into the hot interior of the planet. ...
