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.

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. 

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.

Many of us on Earth live in a home with a street address, city, and zip code. But we have another address, which astronomers and astrophysicists refer to as our "cosmic address": Earth, Solar System, Milky Way, Local Group, Virgo Supercluster, the Universe. Consider the vast scales that our cosmic address spans. Understandably, it's hard for our brains to truly imagine it. Our galaxy, The Milky Way, is populated with somewhere between 100-400 billion stars, one of which is our Sun, an average, run-of-the-mill star.

Albert Einstein (1879-1955) needs no formal introduction. He is remembered around the world as one of history's most brilliant geniuses, and one of its most influential scientists. Einstein is often regarded as the father of modern physics, and he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".

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.

The Mesozoic Era, which lasted from about 252 to 66 million years ago, is divided into three periods, the Triassic, Jurassic, and Cretaceous. During this era, one type of life came to dominate the planet more completely and for a longer period than had been seen before or since; this was the Age of Reptiles. Beginning in the Triassic but especially in the Jurassic period, reptiles came to dominate the oceans, the land and even the skies.

Thanks to the various components that have been put together, the International Space Station is bigger and brighter than all other artificial satellites. With relatively low power magnification, people can see the solar panels radiating outward from the numerous international modules which make up the ISS. The reality of that platform, at the edge of the ocean of space, is pretty astounding when looked at from the perspective of history. Only 120 years ago, mankind did not know if it was possible to fly in a heavier-than-air vehicle.
