Zooming In: Visualizing the Relative Size of Particles

Lately, the world’s biggest threats have been microscopic in size.

From the global COVID-19 pandemic to wildfires ripping through the U.S. West Coast, it seems as though our lungs can’t catch a break, or more aptly, a breath.

But just how small are the particles we’re currently battling? And how does their size compare to other tiny molecules?

Specks Too Small to See

While the coronavirus that causes COVID-19 is relatively small in size, it isn’t the smallest virus particle out there.

Both the Zika virus and the T4 Bacteriophage—responsible for E. coli—are just a fraction of the size, although they have not nearly claimed as many lives as COVID-19 to date.

Coronavirus particles are smaller than both red or white blood cells, however, a single blood cell is still virtually invisible to the naked eye. For scale, we’ve also added in a single human hair as a benchmark on the upper end of the size range.

Particles	Average Size (microns, μm)
Zika virus	45nm
T4 Bacteriophage	225nm
Coronavirus COVID-19 (SARS-CoV-2)	0.1-0.5μm
Bacterium	1-3μm
Light dust particle	1μm
Dust particle: PM2.5	≤2.5μm
Respiratory droplets containing COVID-19	5-10μm
Red blood cell	7-8μm
Dust particle: PM10	≤10μm
Pollen grain	15μm
White blood cell	25μm
Visibility threshold (Limit of what the naked eye can see)	10-40μm
Grain of salt	60μm
Fine beach sand	90μm
Human hair	50-180μm

On the other end of the spectrum, pollen, salt, and sand are significantly larger than viruses or bacteria. Because of their higher relative sizes, our body is usually able to block them out—a particle needs to be smaller than 10 microns before it can be inhaled into your respiratory tract.

Because of this, pollen or sand typically get trapped in the nose and throat before they enter our lungs. The smaller particles particles, however, are able to slip through more easily.

Smoky Skies: Air Pollution and Wildfires

While the virus causing COVID-19 is certainly the most topical particle right now, it’s not the only speck that poses a health risk. Air pollution is one of the leading causes of death worldwide—it’s actually deadlier than smoking, malaria, or AIDS.

One major source of air pollution is particulate matter, which can contain dust, dirt, soot, and smoke particles. Averaging around 2.5 microns, these particles can often enter human lungs.

At just a fraction of the size between 0.4-0.7 microns, wildfire smoke poses even more of a health hazard. Research has also linked wildfire exposures to not just respiratory issues, but also cardiovascular and neurological issues.

Here’s an animated map by Flowing Data, showing how things heated up in peak wildfire season between August-September 2020:

What’s the main takeaway from all this?

There are many different kinds of specks that are smaller than the eye can see, and it’s worth knowing how they can impact human health.

Visualizing Countries by Share of Earth’s Surface

There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.

Today’s visualization uses data primarily from the United Nations Statistics Division (UNSD) to rank the world’s countries by their share of Earth’s surface.

Breakdown of Countries Share of Earth’s Surface

The largest countries by surface area are Russia (3.35%), Canada (1.96%), and China (1.88%).

Together they occupy roughly 7.2% of Earth’s surface. Russia is so big that even if we divided the country between its Asian and European sections, those new regions would still be the largest in their respective continents.

Country / Dependency	Total in km² (mi²)	Percentage of Earth's Surface
Russia	17,098,246 (6,601,670)	3.352%
Antarctica	14,000,000 (5,400,000)	2.745%

Antarctica, although not a country, covers the second largest amount of land overall at 2.75%. Meanwhile, the other nations that surpass the 1% mark for surface area include the United States (1.87%), Brazil (1.67%), and Australia (1.51%).

The remaining 195 countries and regions below 1%, combined, account for the other half of Earth’s land surface. Among the world’s smallest countries are the island nations of the Caribbean and the South Pacific Ocean. However, the tiniest of the tiny are Vatican City and Monaco, which combine for a total area of just 2.51 km².

The remaining 70% of Earth’s surface is water: 27% territorial waters and 43% international waters or areas beyond national jurisdiction.

Areas Beyond National Jurisdiction

In the past, nations adhered to the freedom-of-the-seas doctrine, a 17th century principle that limited jurisdiction over the oceans to a narrow area along a nation’s coastline. The rest of the seas did not belong to any nation and were free for countries to travel and exploit.

This situation lasted into the 20th century, but by mid-century there was an effort to extend national claims as competition for offshore resources became increasingly fierce and ocean pollution became an issue.

In 1982, the United Nations adopted the Law of the Sea Convention which extended international law over the extra-territorial waters. The convention established freedom-of-navigation rights and set territorial sea boundaries 12 miles (19 km) offshore with exclusive economic zones up to 200 miles (322 km) offshore, extending a country’s influence over maritime resources.

Does Size Matter?

The size of countries is the outcome of politics, economics, history, and geography. Put simply, borders can change over time.

In 1946, there were 76 independent countries in the world, and today there are 195. There are forces that push together or pull apart landscapes over time. While physical geography plays a role in the identity of nations, Sheikh Zayed bin Sultan Al Nahyan, the former ruler of UAE, a tiny Gulf nation, put it best:

“A country is not measured by the size of its area on the map. A country is truly measured by its heritage and culture.”

Ever since Apple and other Big Tech companies hit a market capitalization of $1 trillion, many sectors are revving to follow suit—including the automotive industry.

But among those car brands racing to reach this total valuation, some are closer to the finish line than others. This visualization uses data from Yahoo Finance to rank the world’s top car manufacturers by market capitalization.

What could this spell for the future of the automotive industry?

A special hat-tip to Brandon Knoblauch for compiling the original, regularly-updated spreadsheet.

The World’s Top Car Manufacturers

It’s clear one company is pulling far ahead of the pack. In the competition to clinch this coveted title, Tesla is the undoubted favorite so far.

The electric vehicle (EV) and clean energy company first became the world’s most valuable car manufacturer in June 2020, and shows no signs of slowing its trajectory.

All data as of January 15, 2021 (9:30AM PST)

Tesla’s competitive advantage comes as a result of its dedicated emphasis on research and development (R&D). In fact, many of its rivals have admitted that Tesla’s electronics far surpass their own—a teardown revealed that its batteries and AI chips are roughly six years ahead of other industry giants such as Toyota and Volkswagen.

The Green Revolution is Underway

The sheer growth of Tesla may spell the inevitability of a green revolution in the industry. Already, many major brands have followed in the company’s tracks, announcing their own ambitious plans to add more EVs to their vehicle line-ups.

Here’s how a selection of car manufacturers are embracing the electric future:

Toyota: Ranked #2

The second-most valuable car manufacturer in the world, Toyota is steadily ramping up its EV output. In 2020, it produced 10,000 EVs and plans to increase this to 30,000 in 2021.

Through this gradual increase, the company hopes to hit an expected target of 500,000 EVs by 2025. Toyota also aims to debut 10 new models internationally to achieve this goal.

Volkswagen: Ranked #3

By 2025, Volkswagen plans to invest $86 billion into digital and EV technologies. Considering the car manufacturer generates the most gross revenue per second of all automakers, it’s no wonder Volkswagen is looking to the future in order to keep such numbers up.

The company is also well-positioned to ride the wave of a potential consumer shift towards EVs in Europe. In response to the region’s strict emissions targets, Volkswagen upped its planned sales proportions for European hybrid and EV sales from 40% to 60% by 2030.

BYD and Nio: Ranked #4-5

China jumped on the electric bandwagon early. Eager to make its mark as a global leader in the emerging technology of lithium ion batteries (an essential component of any EV), the Chinese government handed out billions of dollars in subsidies—fueling the growths of domestic car manufacturers BYD and Nio alike.

BYD gained the interest and attention of its billionaire backer Warren Buffett, while Nio is China’s response to Tesla and an attempt to capture the EV market locally.

General Motors: Ranked #7

Also with a 2025 target year in mind, General Motors is investing $27 billion into electric and fully autonomous vehicles. That’s just the tip of the iceberg, too—the company also hopes to launch 30 new fully electric vehicles by the same year.

One particular factor is giving GM confidence: its new EV battery creations. They will be able to extend the range of its new EVs to 400 miles (644km) on a single charge, at a rate that rivals Tesla’s Model S.

Stellantis: Ranked #9

In a long-anticipated move, Fiat Chrysler and Peugeot S.A. finalized their merger into Stellantis N.V. on January 16, 2021.

With the combined forces and funds of a $52 billion deal, the new Dutch-based car manufacturer hopes to rival bigger brands and race even more quickly towards the electric shift.

Honda: Ranked #11

Speaking of fast-paced races, Honda has decided to bow out of future Formula One (F1) World Championships. As these competitions were usually a way for the company to show off its engineering prowess, the move was a surprising one.

However, there’s a noble reason behind this decision. Honda is choosing instead to focus on its commitment to become carbon neutral by 2050. To do so, it’ll be shifting its financial resources away from F1 and towards R&D into fuel cell vehicle (FCV) and battery EV (BEV) technologies.

Ford: Ranked #15

Ford knows exactly what its fans want. In that regard, its electrification plans begin with its most popular commercial cars, such as the Mustang Mach-E SUV. This is Ford’s major strategy for attracting new EV buyers, part of a larger $11.5 billion investment agenda into EVs through 2022.

While the car’s specs compare to Tesla’s Model Y, its engineers also drew from the iPhone and Netflix to incorporate an infotainment system and driver profiles to create a truly tech-first specimen.

Speeding into the Horizon

As more and more companies enter the racetrack, EV innovation across the entire industry may power the move to lower overall costs, extend the total range of vehicles, and put any other concerns by potential buyers to rest.

While Tesla is currently in the best position to become the first car manufacturer to reach the $1 trillion milestone, how long will it be for the others to catch up?
