Three Hundred Years of Element Discovery in 99 Seconds

In the vast landscape of scientific discovery, few achievements rival the elegance and impact of the Periodic Table of Elements. What began as a humble attempt to categorize the known elements has evolved into a cornerstone of modern chemistry, guiding our understanding of matter and its interactions. However, the road to uncovering this fundamental organization was not a swift one; it spanned over three centuries and involved the contributions of countless scientists, each adding a piece to the puzzle.

The story begins in the late 17th century when alchemists and natural philosophers first began to explore the properties of substances. One of the earliest attempts at classification came from German alchemist Hennig Brand, who in 1669, discovered phosphorus while experimenting with urine. This discovery, along with others, sparked interest in categorizing elements based on their properties.

Fast forward to the late 18th century, and we encounter the work of Antoine Lavoisier, often hailed as the "Father of Modern Chemistry." Lavoisier's meticulous experiments with combustion and the study of elements laid the groundwork for modern chemical nomenclature and the concept of chemical elements.

The early 19th century witnessed a surge of discoveries, thanks in part to the development of new analytical techniques. Swedish chemist Jöns Jacob Berzelius played a crucial role during this period, developing the modern system of chemical symbols and discovering several new elements, including silicon, selenium, and thorium.

As the 19th century progressed, so did our understanding of atomic structure. Dmitri Mendeleev, a Russian chemist, is perhaps the most famous figure of this era. In 1869, he published the first version of the Periodic Table, arranging elements based on their atomic weight and predicting the properties of yet-to-be-discovered elements. Mendeleev's table not only organized the known elements but also provided a framework for future discoveries, showcasing the power of scientific prediction.

The 20th century brought about a revolution in our understanding of atomic structure, with the discovery of the electron, proton, and neutron. This newfound knowledge led to the development of quantum mechanics, which further refined our understanding of atomic behavior and the arrangement of elements in the Periodic Table.

The animation presented below shows the process of discovering 105 elements over the past 300 years.


Today, the Periodic Table stands as a testament to human curiosity and ingenuity, highlighting the collaborative nature of scientific discovery. What began as a simple list of elements has evolved into a dynamic tool, guiding researchers in their quest to unravel the mysteries of the universe. As we celebrate the 150th anniversary of Mendeleev's Periodic Table, we reflect on the 300-year journey of discovery that brought us to this remarkable milestone, reminding us of the enduring power of science to illuminate the world around us.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population.     Via

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
