About 71% of our planet is covered in water, so our planet is sometimes called a water world.

Unfortunately, only one planet in our solar system can boast so much liquid water. Nevertheless, let’s fantasize and imagine that Earth is not the only planet covered with water.


Mean radius: 2,440 km (1516 miles) / 0.3829 Earths
Length of the equator: 15,329 km (9,525 miles)

Surface area: 7.48×107 km2 (2.89×107 mi2) / 0.147 Earths
Mass: 3.3011×1023 kg / 0.055 Earths

This topographical map created by PythonMaps using Python libraries: raster, NumPy, and matplotlib show the first planet from the sun, with the ocean covering ~71% of the surface, like Earth. Data comes from NASA observations.

Coffee is loved worldwide, not only for its taste and versatility but also because it helps us wake up and feel more productive.

But every nation has its own unique relationship with the caffeinated drink, meaning consumption and cost vary a lot from country to country.

To find out just how much these costs vary, personal finance experts at SavingSpot conducted comprehensive research to reveal the cheapest and most expensive cities for buying a coffee.

SavingSpot used TripAdvisor to gather the price of an americano (or espresso), a latte, and a cappuccino from five cafés based in the capital city of each country.

Cities without five cafés that had menus were omitted. Researchers then averaged the price of coffee. All costs were sourced from local menus before being converted into US dollars.

You have to spend money to make money — so goes the conventional wisdom.

But this is not just good advice for the entrepreneur looking to expand their business. It’s a legal and practical necessity to establish your business in the first place. That’s because, contrary to popular belief, the most challenging part about running a business may not be finding customers; it’s getting one started.

Depending on your country’s public policies and application processes, you might need more or less cash to be able to get a business up and running.

New business owners must shell out for approvals…

U.S. citizens spend in bed an average of 7 hours and 18 minutes each night. They go to bed at 11:39 p.m. and wake up at 7:09 a.m.

But most Americans have conflicts between social clock time and natural solar time. According to the Journal of Health Economics, living on the wrong side of a time zone’s boundary can negatively affect a human’s sleep cycles, health, and even wallet.

The map below shows how time zones shape human behavior. The further West you get in each time zone generally gets bluer. For example, If sunrise in Nashville (Tennessee) is 6:30 a.m., it’s about 7:30 a.m. in Amarillo (Texas). Thus, if sunset in Nashville is 8 p.m., it’s about 9 p.m. in Amarillo. Yet, both these cities are located in the Central time zone.

Reddit user desfirsit made a curious map of what Europeans feel most attached to — their region, country, or Europe.

Average values for the map below got from the answers to three questions from the 2021 European Quality of Government Index.

This map shows the highest attachment in EU countries.

Coal-fired power plants are the U.S.’s most significant industrial polluters. The air pollutants from power factories — carbon dioxide, nitrogen oxides, sulfur dioxide, small particles, mercury, and other air toxins- harm public health, produce harmful ozone smog levels, and fine particulate pollution that damages lungs and shaves years off people’s lives.

Since the year 2000, the Clean Air Task Force has published studies based on work by Abt Associates, U.S. EPA’s health benefits consultant relying on peer-reviewed, posted methodology to quantify the deaths and other adverse health consequences attributable to the fine particle air pollution resulting from power plant emissions…

The Roman Empire reached its largest territorial expanse during the reign of Trajan (AD 98–117), encompassing an area of about 5 million sq km (1.93 million sq m).

The maps below show The Roman Empire at its territorial height.

The topography of the Roman Empire

The Roman army mainly was infantry based, which was great in hilly or mountainous terrain but at a critical disadvantage to cavalry on the open flats. As a result, the Roman Empire’s frontiers mainly situated on one of the following:

  • Coast (the entire Mediterranean basin, Iberia, most of northern and western Europe)

Since its inception in 1989, the internet has been in a phase of endless flux as millions of various sites emerged and then fell by the wayside. Many monstrous corporate players have arisen from this first chaos over the decades and have since become dominant in their niches. This trend has been notably visible in the last decade. As Google, Youtube, Amazon, and Facebook have swallowed most of their former contestant on a global scale. Frequently, this has started rising blame for monopolistic behavior, censorship, and misuse of user data.

Many nations still have many flourishing national websites and social…
