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.

Standing around 10 feet tall and weighing several tons, woolly mammoths seem like the stuff of legend, but ancient cave art indicated that unlike dinosaurs, woolly mammoths were contemporaries of early humans, with the last ones going extinct only about 4,000 years ago. All of that explains why people have long been fascinated by woolly mammoths and have even envisioned bringing them back to life via genetics sometime in the future.

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.

In 1977, two spacecraft were launched from Earth to explore the outer Solar System, and incredibly, the now-ancient technology from the 1970s is still working, sending daily reports back to the planet that sent the two robotic envoys on their way, over 40 years ago. Voyager 1 and 2 have done far more than accomplish their original missions. In fact, they are now exploring interstellar space, far beyond the outer planets, in the cold wasteland between the stars.

Tycho Brahe: The Life and Legacy of the Legendary Astronomer Who Mentored Johannes Kepler examines the life and work that made him one of history’s most important scientists. You will learn about Tycho Brahe 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.

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.

This quick but comprehensive primer, The Illustrated Guide to the Universe by Bill Andrews of Astronomy magazine, gives a complete overview of our universe, starting with our solar system before moving outward to explore the rest of the Milky Way Galaxy and beyond.

Machine Learning: The History of Automating Computers to Observe and Analyze Data looks at the attempts to develop machine learning, from successes to failures. You will learn about machine learning like never before.

They say that one is subjected to a sobering sample of what can only be described as an existential crisis when traversing the golden and seemingly infinite terrain of the Sahara Desert. If one climbed any of the countless sand dunes and twirled around in a place, particularly under the starlit sky, they would scarcely be able to tell east from west without a compass, for there would be nothing but dizzying carpets of indistinguishable sand hills unfurling into the distant horizon.

Ever since the human mind developed the capacity for thought, people have pondered not just the meaning of life, but the genesis of the world, the universe, and all the natural marvels and precious forms of life within it. To this day, all of these intricate subjects continue to be matters of great contention, and they are often best encapsulated in the debate between creationism and evolution. On the one hand are those who are adamant that it was God, or some other supreme being, that designed and crafted every detail of the universe.

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.

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.

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.

The oceans of the world have always had an air of mystery. About 71% of the Earth's surface is covered by water, and until the 20th century no one had plumbed its depths. Even today the bigger seas and oceans remain a largely unexplored frontier, with new species being discovered every year. Thus it comes as no surprise that countless legends have arisen of strange creatures lurking in the depths.

In 1676, Sir Isaac Newton famously wrote in a letter to philosopher Robert Hooke, "If I have seen further it is by standing on ye shoulders of Giants." By the time he died, Newton had become science's greatest giant, and every scientist who has followed him has stood on his shoulders. Newton is widely considered the most influential scientist in history, best known for the discovery of gravity and the subsequent laws of motion that he theorized.

The hurricane that struck Galveston, Texas, on September 8, 1900, killed between 6,000 and 12,000 people. Prior to advanced communications, few people knew about impending hurricanes except those closest to the site. In the days before television or even radio, catastrophic descriptions were merely recorded on paper, limiting our understanding of the immediate impact. Thus it was inevitable that the category 4 hurricane would cause almost inconceivable destruction.

Around eight o'clock a.m. on December 26, a massive earthquake registering 9.1-9.3 on the Richter Scale struck off of Sumatra, Indonesia, making it the third strongest earthquake ever recorded by seismographs. On top of that, the earthquake shook for nearly 10 minutes and generated incredibly strong tsunami waves. Thanks to the element of surprise, people in the region had virtually no warning of what was coming. The tsunami waves pulverized entire towns and swept away hundreds of thousands of people across Southeast Asia.
