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.

The early history of our planet 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 current view of science is that planet 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 in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge.

Project Gemini is a neglected part of the US space program. Sandwiched between the excitement of Project Mercury and the sending of the first American astronauts to space and the euphoria of the Apollo Moon landings, Gemini was a step forward rather than a dramatic leap. However, this project achieved many important firsts, including the first spacewalk, the first rendezvous and docking between two spacecraft, the first flights of more than one week’s duration, and many more.

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.

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.

World War I, also known in its time as the Great War or the War to End all Wars, was an unprecedented conflict in terms of its sheer scale. Before 1914, flying machines were objects of public curiosity. By 1918, all the major belligerents were fielding squadrons of fighting aircraft. Bombs were dropped on Paris in August 1914, and Zeppelins bombed Belgian forces as the Germans advanced on Liège. Zeppelin raids on Britain would continue for nearly four years. These raids and the attempts to stop them would be carried out at the cutting edge of new technology.

In the list of popular American geological oddities and attractions, one sizeable phenomenon remains surprisingly unfamiliar to the average citizen. This may be due in part to its remote desert location, but perception of the Salton Sea in Southern California is also laden with environmental concerns and is in a constant state of flux. The extensive body of inland saltwater hides a glorious commercial past and has served as an important wildlife preserve but approaches a seemingly inevitable crisis in the coming decade.

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.

At 9:32 a.m. on July 16, 1969, time stood still throughout the world as thousands converged on the Kennedy Space Center and millions tuned in on live television. At that instant, the first rumbles began to shake the ground, as a small spacecraft attached to the giant Saturn V rocket several hundred feet tall started lifting off. Apollo 11 was on its way to a historic first landing on the Moon.

In virtually all fields of human endeavor, Athens was so much at the forefront of dynamism and innovation that the products of its most brilliant minds remain not only influential, but entirely relevant to this day. In the field of medicine, the great physician Hippocrates not only advanced the practical knowledge of human anatomy and care-giving, but changed the entire face of the medical profession.

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.

Pavlov's dogs are to Psychology 101 what Rome is to antiquity classes. This particular series of experiments and the concept of classical conditioning likely ring a bell for many readers and listeners because they have been referenced in countless texts, both scientific and otherwise, and they have seeped into various forms of pop culture throughout the years.

“My apparatus projects particles which may be relatively large or of microscopic dimensions, enabling us to convey to a small area at a great distance trillions of times more energy than is possible with rays of any kind. Many thousands of horsepower can thus be transmitted by a stream thinner...

In 1869, the Atlantic Monthly magazine published a new novella in serial form. This bizarre tale, The Brick Moon, was written by a historian (and Unitarian minister) named Edward Everett Hale, who had already written several well-received novels and articles. However, this was something completely different today, as it was in the genre of what is today considered science fiction. Many people compared the new work to the previous novels of French writer Jules Verne, including From the Earth to the Moon, but Hale’s work was presented as a genuine account of a previous experiment.

We take time for granted as it passes during every moment of our existence. Other things may change, but time remains constant and predictable. The past, the present, and the future exist within a harmonious, reliable, and never-changing system. Or at least that’s how it seems. It was Albert Einstein who, in 1905, first theorized that time might not be quite as straightforward as that. In one of the most influential papers on physics ever published[1], he proposed something called “time dilatation.” 

Mayan Astronomy: The History of the Maya’s Measurements of the Planets and Stars examines what is known and unknown about the Maya’s astronomy, and why their astronomy was among the most accurate in the world.
