Which of these maps did you find most interesting?

In Turkey because everyone drinks tea they just give it to you without asking. People drink so much tea that you can drink tea in a hairdresser. Tea is like water in Turkey. You just drink it every day.

There are strong mathematical reasons for A4 papers. "A standard" serie is made so, that every time you cut in half a paper the ratio of the sides is the same (golden ratio) AND the first one A0 has a square meter surface

The fact that there's more Portuguese people in Brazil than in Portugal got me LOL And also half of Italy

Fun fact: Portugal was a main importer of tea to Europe but never developed a serious habit of drinking it. It was more like a high society snob thing. When Catarina de Bragança married the King of England in 1662 she brought with her the habit to have tea in the afternoon. British nobility loved all those exquisite Asian porcelain and etiquette. It became a hit in all Britain's high society and still is verifiable in 2021.

The most important map there was undoubtedly the platypus one.

I appreciate it that you always show the maps on the thumbnails at first! Think this just has to be said haha🎉

The dots on the lactose maps is not where they “conducted studies”, but where localised “pockets” of lactose tolerance are found in regions otherwise intolerant to lactose. Typically among herders ethnic groups who raise cattle, and co-evolve the ability to digest milk even through adulthood as it provided an evolutionary advantage as an additional food rich in nutrients. In Northern Europe, milk provided a different evolution advantage as a source of vitamin D in latitudes where there’s not enough sunshine for most of the year to produce it that way...

Romantic languages sounds nice and they probably are, however romance languages is the correct definition.

3:54 in ancient Greek and some other scripts it was common to alternate writing direction in each line. This style of writing is called Boustrophedon

In Turkey,tea wasnt popular before 1930s.Coffe was the most popular drink but we couldnt grow them in our lands so Atatürk brought tea from russia and planted them at black sea region.We gained nice drink and also less dependent economy

Our lebanese community is very strong in São Paulo state. Many fled Lebanon's Civil war, and most are christians instead of muslim. They are so integrated to brazillian culture that one will only notice their origin through their surname.

Charles University in Prague should be ahead of Vienna.

As someone who resides in central Wisconsin, the majority of people in this part of the country have Polish heritage. We even have the polish heritage highway. I have met a number of Polish immigrants fishing the Wisconsin river as well, they’re some of the nicest/ friendly people.

Fun fact: Paraná, the Brazilian state with high slavic descendence, is known in Brazil (mainly on the Internet) as “The Brazilian Russia”.

Actually, Prague's Charles University is older than Vienna's.

Nice soundtrack lol. I noticed Konigs March and Prussias Glory towards the middle and end.

6:18 how is Vienna, which was founded in 1365 5th, while Krakow with 1364 isn't ?

Besides the selection of maps being extremely interesting, the highlights for me are the comments, always showing precious insight.

6:20 Charles university is older than the university of Vienna

On the outlets - different countries in Europe have a different outlets however they should be compatible with one another hence the same colour

This is one of the very few channels to not have clickbait

"What type of outlet do you use?" "The angry robot."

8:50 People of lebanese (and syrian) ancestry are not common to *see* in Brazil despite their combined 13 million, simply because there are 210 million people in the country. Their contributions, however, can be seen more than the ones who brought it, specially in the culinary.

The reason the electrical outlets are color coded is because they are largely intercompatible. For an example, the type B is just a type A with ground. The type E, F, and K are all the type C but with different ways of implementing the ground connection. The type K decided to put an additional pin on the plug. While the E decided to put a pin in the outlet instead. While the type F uses a clip in the outlet that hugs around the plug. (partly to provide an even more snug fit to not have accidental disconnects.) The type E and F are also intercompatible in daily use, since most type F plugs support the type E as well. (While the type K that is only used by Denmark isn't intercompatible with anything... they if anyone should switch to the type F that all their neighbours use....) The reason a lot of the map is green is thanks to the abhorrent Europlug. The only plug that is worse than the type A as far as electrical safety is concerned... (Its "insulated" pins have a tendency to get snagged in the socket and leave some nice wires poking out with power still applied to them...) Also, the type B is upside down in the picture, the ground pin should officially be on the top, so that the ground pin protects the end user if anything reasonably thin falls and slides in between the plug and socket, since the socket isn't recessed nor is the pins on the plug insulated to stop someone from touching live metal. (And usually one can pull the plug out about 5 or so mm and still have electrical contact. The round type C derived plugs are recessed for a reason. (and that reason is actually so that one can hang a transformer onto them without the pins shearing off, back in the "good" old days when such weighed a few kg if one needed some actual power....)) The Brits made the type G with insulated pins, and also making the plug polarized, as well as stuff in a fuse into the plug itself. Polarizing the plug saved them from having an additional switch contact if one have an Edison screw lamp, but there were more practical concerns back in the day when there were a larger risk of metalwork becoming live. The fuse is to protect the cable, but the fuse in one's distribution-panel/fusebox is already going to trip regardless, a mains fault is a fairly energetic affair. But this plug side fuse is largely redundant, all appliances should have a mains side fuse regardless, at least if sold in the EU, USA, Canada, Australia, etc, etc. Though, the main issue I have with type G is how bulky it is, and that it complicates cable management. (Though, then there is also all the misconceptions surrounding square pins and contact resistance.... But this is true for the Type, A, B, H, I as well...) My own opinion is that the world should all just use the type F plug, except in applications where more than 16 Amps is needed. Since it already is the most common plug in the world, it is sturdy and compact, and can handle a fair bit of power. (For higher current needs, there is already IEC 60309 (or CEE form), these are though a complicated mess to be fair, and really bulky, since they are used in heavy industry, but can also be found at shipping-/air-ports.)

For the elctrics outlet it would also interesting what electrical current you get around the world. In Europe it is 220-240V while in the USA it is 120V I believe. That means when the world would switch to one kind of outlet also the Voltages and Amperes have to be adjusted so you really can use it anywhere

Belgium is wrong in the map of universities. Ghent is depicted as the oldest one, while it's actually the University of Leuven that is much older and just also very old compared to others.

US Letter is honestly Great. It’s the perfect size for pretty much anything except big drawings

My favorites were the paper size and outlet type maps. Really cool. Thank you.

@9:06 The reason why they are color grouped but look slightly different in North America, but similar enough to group (e.g., an extra, missing, or false prong) is the ground wire and dual purpose for partial reverse compatibility. All North American (A&B) electrical outlets require at minimum 2 wires (A), hot (+) and neutral (-), but if the device being used requires a ground-wire (B), then the plug will have 3 prongs. Think of two devices: your refrigerator (B/3-wire ) and cell phone (A/2-wire) could work using the B/3-wire outlet to work, but you could not plug a refrigerator (B) into a 2-wire (A) outlet because the manufacturer or electrical code requires the 3rd wire for grounding the device.

From the little I can remember about electrical outlets, any of the outlet types that are grounded (like type B) are ideal in most situations. Many older homes in the US use type A but all new homes use type B. So in the pursuit of universal outlets there should be an effort for an outlet that is grounded.

Definitely more map videos, please!

4:08 Taiwan is also highlighted

I love this video very interesting thanks for sharing

8:15 beautiful song starts playing

Don't know why the map at 06:00 shows Ghent 1817 in Belgium since the oldest and best known Belgian university is the KU Leuven (Catholic University of Leuven) first established in 1425.

I love these videos... Maps are so versatile!

8:55 yes, it is grouped that way because of compatibility. From experience i know that despite Portugal using type-C electric outlets and the most common in Switzerland being the type-J one, they're compatible and to make a type-J plug work in a type-C socket, you just remove the extra pin and it works just fine.

For plug outlets I understand grouping A and B because A can plug into B as well. They are both very common in the US. For example, in the room I'm currently in there are 4 outlets one on each wall, the north side has an A outlet, the west side has an A outlet, the south side has a B outlet, and the east side has a B outlet. Another room, my kitchen has 4 outlets 1 on the east, 1 on the west, and 2 on the south. They are A on the east, but B on the other 3.

Really cool maps is a great way to describe really cool maps!

5:45 In Wisconsing is a town called New Glarus. In Switzerland there is a canton (state) called Glarus.

More, please!

Yes more of these please!

I love how you play preussens gloria in the background❤️

9:00 - I lived in Italy 20 years ago and there were three different variations in the house. My electrical life depended on having the right combination of adapters.

The platypus map is indeed very useful. Platypus' rock - they're awesome animals.

8:20 people of Syrian and Lebanese ancestry are very often their countries "missing" christian community

Where did your signature bell at the sound of your videos come from? You’ve had it for years and it would be interesting to see why you included it!

In the USA the types A and B (brown) are both found. The third pin is an earth ground. A two prong cord can fit in a three prong outlet, but you need an adapter, hopefully with a grounded connection, to go the other way. Most new construction uses three prong outlets. There may also be a relationship with voltage levels and AC frequencies involved in the catagorization.

Big thumbs-up for the cool platypus map!

Wow that was cool please do more of these

2:14 man Illionis is such a great state i mean Illinois is kinda similar so yeah there's that

Awesome I always enjoy your videos, but that one specially was so light and broad, perfect! . Also your own comments sounded very reasonable and personal, great job, it was very fun to watch! Ótimo conteúdo, todos os seus vídeos são extremamente educativos, didáticos e de fácil compreensão, mas na minha opinião acrescentar mapas sobre a distribuição de ornitorrincos só porque são super interessantes ou o mapa sobre as tomadas deram um caráter menos circunspecto ao vídeo, mais leve e divertido!

I wonder what's up with all those Montenegrins in Alaska

Very interesting video!

Yes, the outlets are grouped by compatibility. The third holes in the orange and light blue are for grounding. If the plug has only two prongs, it can be used in all of those within the group. If it has three prongs, it requires the specific three-holed outlet. Also, some countries electrical systems operate on a 110-127 volt (some also have 230/240 available for higher voltage appliances). The majority only operate a 220-240 volt system. Fortunately, most modern computers, tablets, smartphones, etc. are dual voltage and work in either system. But if, for instance, you plug a 120 volt hairdryer into a 220 socket, it will fry the wires inside of hairdryer, and potentially catch on fire.

I think the important part of the lactose map is the word "indigenous" and it shows the origin of milk consumption in Europe.

The outlets for the US, Japan and other orange countries have two because the older type, the two pronged, aren't grounded while the three pronged are. You can use a three pronged on a two with an adapter. That said we also have different plugs for our stoves and driers(and a few others) that have three but in a different layout from the 120v, their are even 4 pronged plugs.

I love interesting maps, and I love the way you present them. ^_^

The colour groupings on the electric plugs maps : voltage... 110 in US, 220 in Europe... as for tea drinking in the Middle East, it is a staple of local hospitality...

9:07, really USA uses A, B, and I. You will find I in RV parks and factories. Maybe slightly modified.

I love your vids herbal knowledge.

once again a great episode

Nice, especially the map with the platypus.

Excelente análise! Espero ainda poder conhecer a Universidade de Coimbra, nem que seja pra estudar um curso rápido.

Really cool and detailed information about each segment. Greetings from Ireland 🇮🇪

Saw the oldest university map on Reddit, loved looking at it. I was surprised how recent Iceland's university was.

DEFINITELY do one on universities, please! This would be cool for Africa, the Middle East and China as well ....

In Morocco, which is not an Arab country btw, this is a stereotype, we right from left to right too. In addition to Arabic and Darija, we use French and Tamazight, the last two languages are read from left to right

with electrical outlets, they are grouped because its literally the same outlet, just one might have a ground plug/no ground plug or if it does have a ground plug the placement of that ground plug. A & B are the same but B has a ground plug, C, D, & F are the same but D has the ground plug and F has clips on the side

The platypus one is the best part of the video

I always wondered what parts of Australia to find platypus. Now i know. Thank u.

Nice background music :)

Plz do make a part 2 of this video

3:27 That region of Africa is usually called "Central Africa", not "West Africa", though it does have an Atlantic coast. This is mainly because "West Africa" tends to refer to the further west and north region that has the Atlantic to the south and the Sahara to the North.

I always find it funny when eurasians refer North and South Americans as one continent while still separating Europe and Asia

At 2:16, we can tell the states that give the most are also the most populous.

It is always fun to hear German Marches in the background of your videos. Greetings from Northern Germany

9:05 They are grouped because they are compatible for plugs without earth (Like the plugs for smartphones, ...).

Oldest universities around the world would be cool. I went to University of Delaware, which was formed in 1833. It's direct predecessor was founded in 1743 and chartered in 1769. It has one of the strangest US mascots, the Fighting Blue Hen. I did my postgraduate work at University of Colorado Boulder, founded in 1876, and went back to school at Santa Fe Community College, now Santa Fe College in Gainesville, FL, which was established in 1965.

Different outlet shapes were partly designed to discourag the smuggling or piracy of electronic devices. Just how VHS and DVDs had separate regions where they would only work in their own region.

I love how he starts with the ones on the thumbnail.

The University of Helsinki was founded in Turku as the Royal Academy. Turku was the Capital during Swedish reign but after Russia conquered the capital was moved to Helsinki in 1829 and along came the university.

4:25 Historically some languages used to alternate every line between left to right and right to left. So you'd go from left to right, then go down to the next line and go right to left with inverted letters and go right to left, then at the end go down and left to right again. Not sure if the latin ones ever did that, possibly Carthagian? I don't remember, but I know it *was* a thing back in history...

These maps have been approved by a turtle

I live in Chile and I never would've thought that more than half of the world uses a different type of paper than us.

The Gregorian calendar comes from the 16th century CE. It is, however, an adjusted version of the Julian calendar, which was Roman.

Yes, the world should use the schuko plug, since most of the world is already compatible with it. But the child safety standard (mandatory in some of the countries) is better designed than the UK one, and is even adult safe. The schuko plug is reversable, like USB type-C. It has earth, it has no exposed pins, and it's built to withstand several kilograms of force and high voltage. It's a very clever design for a plug, and it's very understandable that so many countries use it.

A video about the oldest schools would be very cool!!

8:56 The reason they grouped them together is probably to reduce the number of countries that have to be mixed in color to being only China (that I can see). For example, both the A and B types are common in the USA, though B is much more common for outlets, even though many plugs are of type A, which can plug into either A or B outlets.

More maps please

1:10 "Don't just assume it's right because it's presented nicely and widely distributed online" ✅

6:58 it's the imperial measurement system, look at the inch sizes.

We use different outlets because innovators in each area invented their own outlets independently, without having any idea of what was being done elsewhere. Changing would require almost everyone replacing not just all their wall outlets but also either rewiring or replacing all their appliances.

Just got this in my recommendations

The final map is my favorite

Brazil used to have an outlet which was compatible with the flat American and the [most common] European one. Now we have a new type compatible with none, and which is based on vaguely technical grounds.

i like these videos, plwase do more of them

Would love to see the university video

The paper size map... It all makes sense to me now. Whenever I try to print my American documents in Germany it never fits the whole paper, it always gets cut off!
