300 Years of Element Discovery in 99 Seconds
Chemical elements are the building blocks of modern society.
Our fundamental understanding of the periodic table has allowed us to: build rockets that can withstand scorching temperatures; harness permanent magnets that can help us generate electricity; erect ultra strong and tall skyscrapers; and discover compounds that can eradicate disease around the world.
But while we take this elemental knowledge for granted today, there was a time not too long ago when the periodic table was mostly empty.
The Elemental Dark Age
Today’s animation comes to us from materials scientist Dr. Jamie Gallagher and it chronicles the last three centuries of discoveries for the periodic table of elements.
It starts in the year 1718, around time of Isaac Newton, when the scientific method was young and the knowledge we had around chemistry was still very incomplete.
At the time, we knew about elements like iron, copper, gold, silver, and lead – but the periodic table contained just 11% of elements compared to today.
A Flurry of New Discoveries
In the late 18th century and early 19th century, researchers started seeing patterns that allowed them to make new discoveries.
Specifically, the years between 1788-1825 were particularly fruitful – over this stretch, the periodic table more than doubled in size from 26 to 53 elements.
Lithium, calcium, titanium, vanadium, tungsten, palladium, silicon, niobium, and uranium were some of the elements to join the table during this critical time period.
Formation of the Periodic Table
In the 19th century, the French geologist Alexandre-Emile Béguyer de Chancourtois was the first to notice the periodicity of elements, and in 1862 devised an early version of the periodic table.
A few years later, in 1869, Russian chemist Dmitri Mendeleev created a table organized by atomic mass, which more closely resembles the one we use today.
Here were the elements known at the time:
While nowhere near complete, it includes many of the elements that are used in modern life today.
The Final Touches
By the 20th century, chemistry was becoming more formalized, as we knew more about atoms, protons, electrons, neutrons, and so on. This led to the fleshing out of the periodic table as we know it.
By this point, researchers were even creating radioactive, synthetic elements like unununium (Atomic number 111) which is now known as Roentgenium. Like many other late element discoveries, this one is not found in nature and the most common isotope has a half-life of just 100 seconds.
These final discoveries, some of which happened in recent decades, helped bring up the periodic table to its current size: 118 elements.
Visualizing 200 Years of U.S. Population Density
This animation shows the population density of U.S. counties between 1790 and 2010, showing the westward expansion of the country’s population.
Visualizing 200 Years of U.S. Population Density
At the moment, there are around 326 million people living in the United States, a country that’s 3.5 million square miles (9.8 million sq km) in land area.
But throughout the nation’s history, neither of these numbers have stayed constant.
Not only did the population boom as a result of births and immigrants, but the borders of the country kept changing as well – especially in the country’s early years as settlers moved westwards.
U.S. Population Density Over Time
From a big picture perspective, here is how population density has changed for the country as a whole over the last 200 years or so:[table “404” not found /]
But today’s animated map, which comes to us from Vivid Maps, takes things a step further.
It plots U.S. population density numbers over the time period of 1790-2010 based on U.S. Census data and Jonathan Schroeder’s county-level decadal estimates for population. In essence, it gives a more precise view of who moved where and when over the course of the nation’s history.
Note: While U.S. Census data is granular and dates back to 1790, it comes with certain limitations. One obvious drawback, for example, is that such data is not able to properly account for Native American populations.
“Go West, Young Man”
As you might notice in the animation, there is one anomaly that appears in the late-1800s: the area around modern-day Oklahoma is colored in, but the state itself is an “empty gap” on the map.
The reason for this? The area was originally designated as Indian Territory – land reserved for the forced re-settlement of Native Americans. However, in 1889, the land was opened up to a massive land rush, and approximately 50,000 pioneers lined up to grab a piece of the two million acres (8,000 km²) opened for settlement.
While settlers flocking to Oklahoma is one specific event that ties into this animation, really the map shows the history of a much broader land rush in general: Manifest Destiny.
You can see pioneers landing in Louisiana in the early 1800s, the first settlements in California and Oregon, and the gradual filling up of the states in the middle of the country.
By the mid-20th century, the distribution of the population starts to resemble that of modern America.
Population Density Today
The average population density in the U.S. is now 92 people per square mile, although this changes dramatically based on where you are located:
If you are in Alaska, the state with the lowest population density, there is just one person per square mile – but if you’re in New York City there are 27,000 people per square mile, the highest of any major city in the country.
The Top Earning Celebrities, Dead and Alive
Celebrity status can be a powerful tool for building a fortune. These infographics visualize the world’s top earning celebrities, both living and dead.
Wealth does not always follow fame, but when properly monetized, stardom can be a powerful tool for building a fortune.
The act of turning one’s self into a marketing machine is epitomized by 21-year-old Kylie Jenner, who was the fourth highest earning celebrity in 2018. Leveraging her massive social media following, Jenner has turned Kylie Cosmetics into a force to be reckoned with. Recently, Forbes valued her company at over $900 million.
Today, we look at not only the world’s top earning living celebrities, but also the estates of the celebrities who are no longer with us as well.
Fame and Fortune
With a nickname like “Money”, it comes as no surprise that 2018’s top earning celebrity was Floyd Mayweather. The boxer’s bouts in 2015 and 2017 are still the top earning pay-per-view fights of all time, with the respective payouts propelling him to the top of the celebrity earnings list. His most recent opponent – Conor McGregor – also cashed in big, ranking 12th on the celebrity rich list.
Here is a full look at last year’s top earning celebrities:

Many celebrities earn big sums of money on specific contracts, so it makes sense that the top 10 shuffles a lot from year to year. Despite this, soccer star Cristiano Ronaldo is the sole celebrity to remain on this list for every year covered by the visualization.
Ed Sheeran’s Divide album was a runaway success earning him $110 million last year. Not only did the singer sell 1.1 million albums – an impressive feat in the digital age – he was the most streamed artist of 2017.
One somewhat surprising entry into the top 10 is Judy Sheindlin – better known as Judge Judy. Sheindlin reaped a huge windfall after selling her extensive 5,200-episode library to CBS.
Some celebrities are so iconic that their influence extends well beyond their own lifespan.
Michael Jackson’s music is still thrilling listeners around the world, and as a result, his catalog is raking in the posthumous profits. In 2018, the late singer’s estate earned more money than any living celebrity, adding to the $2 billion already amassed since his passing in 2009.
Below is a full look at the top earning dead celebrities:

For the first time since 2006, Albert Einstein has fallen out of the top 10. The Hebrew University of Jerusalem owns the rights to Einstein’s likeness, and in the aughts the “Baby Einstein” brand helped them (and Disney) amass a fortune. The popularity of the Baby Einstein brand is waning, but other licencing deals could bump the famous physicist back into the list at some point in the future.
No Business Like Show Business
Even celebrities who passed away decades ago can continue earning a shocking amount of money. While income streams like song royalties continue rolling in automatically, some savvy companies purchase estates from family members and take the marketing of deceased personalities to the next level.
Companies like Authentic Brands Group, have turned timeless icons like Marilyn Monroe and Elvis Presley into full-fledged brands generating tens of millions of dollars per year through licencing and royalties.
Artists like Bob Marley and Dr. Seuss produced a body of work that still captures our imaginations today, so it makes sense that their estates continue to profit as time goes on.
