The current view of science is that Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life on Earth, and then the first single-celled life-forms, early bacteria and algae, began to emerge. It’s unknown where they came from or even if they originated on this planet at all, but this gradual development continued until suddenly (in relative geological terms), more complex forms of life began to emerge.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit. By the time the Hubble telescope reached orbit, it was already the world’s most famous telescope, but it was also the most scorned. The telescope cost nearly $2 billion more to complete than anticipated, and to make matters worse, the first images it sent back were skewed.

When people look up into the night sky, the stars seem fixed and immutable, as unchanging as the darkness of space itself, but the truth is that stars are born, live, and die in a never-ending cycle of creation and annihilation. These cycles stretch over such vast spans of time that to short-lived humans, they seem to last forever. No one knows just how many stars there are, but their number is almost beyond comprehension.

Today the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 “winning” the Race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the Solar System.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold.

The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans.

Mankind's obsession with felines is an enigma in and of itself. Unlike dogs, famously known as man's most excitable, trustworthy, and loyal friend, cats are oftentimes indifferent, guarded, and yet finicky little furry creatures that only yearn for attention and affection when one is neck-deep in work or otherwise preoccupied. And still, people adore them all the same.

The acrid stench of asphalt and sulfur singes the hairs of people’s nostrils, and when the blustering winds subside, the potent miasma lingers in the air. To the untrained eye, the La Brea Tar Pits seem to be nothing more than simply pools of thick, viscous black sludge...The pit’s contents have spelled the doom for a countless number of creatures both large and small, from legions of insects to mighty mastodons, mammoths, and snarling saber-toothed cats from the Pleistocene Era. La Brea Tar Pits are considered by many scientists to be among the greatest finds in modern history.

Today, the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 "winning" the race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the solar system. Moreover, the notion that America "won" the Space Race at the end of the 1960s overlooks just how competitive the Space Race actually was in launching people into orbit.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. The Triassic Period: The History and Legacy of the Geologic Era that Witnessed the Rise of Dinosaurs looks at the development of the era, the extinction events that preceded it, and how dinosaurs began to evolve in the Late Triassic. You will learn about the Triassic Period like never before.

One of the most famous, and important, intellectuals to hail from Denmark is Niels Bohr, a world-famous physicist and one of the patriarchs of quantum theory. Given the vibrant, peaceful haven that is Denmark today, it’s somewhat ironic that Bohr played an instrumental role in the development of the atomic bomb. Even so, the truth and depth of the matter, much like the self-professed pacifist himself, is far more complex.

Discover the the life and accomplishments of Max Planck, theoretical physicist whose revolutionary discovery of energy quanta and formulation of fundamental quantum theory allowed for countless others to expand on the knowledge of atomic processes.

Desde que la mente humana desarrolló la capacidad de pensamiento, las personas han considerado no solo el significado de la vida, sino la génesis del mundo, el universo y todas las maravillas naturales y formas de vida preciosas dentro de él. Hasta el día de hoy, todos estos temas intrincados continúan siendo asuntos muy discutidos, a menudo mejor encapsulados en el debate entre el creacionismo y la evolución.

The Curie name is without question a household name in the world of science, and even those unfamiliar with radiation have heard of Marie, the matriarch of the prodigious family, and the multiple glass ceilings she shattered with her literally radioactive findings. While this recognition is certainly well-deserved, many have neglected to acknowledge the momentous contributions made by her colleague and husband, Pierre.

The tens of millions who perished in the First World War – not to mention the horrendous turmoil that culminated in the outbreak of its successor – understandably marred the conception of the first decades of the 20th century. However, during that time, unparalleled minds from all over the globe unsnarled age-old mysteries and perfected prevailing theories, conjuring up wave after wave of breakthroughs that catapulted the world of science to unprecedented heights.

The tens of millions who perished in World War I understandably marred the conception of the first decades of the 20th century. However, during that time, unparalleled minds from all over the globe unsnarled age-old mysteries and perfected prevailing theories, conjuring up wave after wave of breakthroughs that catapulted the world of science to unprecedented heights. Owing to this influx of novel ideas and innovative concepts, conferences had to be assembled to keep the relevant scientific spheres apprised of the latest advances.

While it would be impossible to name every individual who has contributed to the ever-advancing field of science, it almost goes without saying that one of the most important was Louis Pasteur, father of microbiology and modern immunology. Apart from propelling the field of vaccination to new heights, this visionary scientist would also revolutionize a significant part of the beverage industry, and highlight the importance of sterilization. These are only some of the extraordinary achievements on Louis' glaring résumé, one so well-rounded and extensive that it beggars belief.

Dr. Stephen William Hawking, British mathematician, theoretical physicist, and cosmologist, is the face of twenty-first century physics, and yet cannot speak directly to his audience. He is no longer able to move his limbs due to the incapacitating effects of ALS, Amyotrophic Lateral Sclerosis. The affliction is better known in the United States as "Lou Gehrig's Disease," named after the great American baseball player. Since 2009, in fact, Hawking can no longer operate his wheelchair.
