What are you waiting for? Did you know that a baby had more bones in its body than an adult?
An adult has 206 bones in their body whereas a newly born baby has almost 300. This is because newborn babies are born with some of their bones separated to make it easier for them at childbirth. If we were to touch a baby’s head very carefully, we would feel some softer parts called fontanel, where they are joined by cartilaginous tissues and with the passing of time these bones and tissues become the skull. The truth is, nature is very wise, don’t you think?
And did you know that the breath of newly born babies does not smell?
This is because they don’t have any teeth which is where the bacteria responsible for bad breath called halitosis, is found. So, as you are not a baby, you must clean your teeth very well after each meal so as not to have bad breath. Don’t forget, ok?
Did you know that most babies cry without tears?
The reason for this is a simple one. The tear duct in a baby’s eyes is not totally open at birth and so tears can’t pass through. In some cases these ducts don’t open until the baby turns four months old. Though this happens, we cannot think that when a baby is crying, it’s only pretending. During the first months of a baby´s life, crying is the most practical way of communicating, so when a baby cries, we must go to them or notify an adult so that they can find out what the baby wants. We must take great care of newborn babies, because don’t forget, we were all babies once.

Educational Videos and songs for Kids. Today we’re going to learn about mammals!
The diversity of mammals is amazing. They can be as huge as these whales,or as tiny as this cute little balancing mouse. They can be noisy like this howler monkey, or quiet like this hedgehog with its sharp, pointy spines.
Even though they’re amazingly diverse, all mammals have a number of common characteristics you should know about, so you can recognize and differentiate them.
All mammals are viviparous, they are born from their mothers’ womb. In their early stages of life, they feed on milk, which they get from their mothers' breasts where the mammary glands are. And that’s why they’re called mammals. And when they’re little, they’re so cute, aren’t they?
Mammals reproduce by internal fertilization when a sperm cell and an egg join inside the female.
As you can see, they have teeth inside their mouths, and lips around them so they can eat and suck milk.
Most mammals’ bodies are covered with hair, and all mammals breathe with their lungs, even if they live in the sea. Look at these dolphins coming to the surface for air.
The body temperature of mammals doesn’t depend on whether it’s cold or hot outside, because they can maintain their own internal temperature.
Almost all mammals are terrestrial, like camels, and jaguars. Some live in the sea and are called Marine mammals,like these dolphins,and these seals,There's even a flying mammal, bats are the only mammal that flies.
Mammals have four limbs, which vary depending on where they live. Land mammals have legs,so they can walk,and run when they need to,and Jump.,and sometimes even climb.
Marine mammals have fins so they can swim very fast...
And flying mammals have wings so they can fly through the sky...
Do you know which is the most wonderful mammal that lives on Earth?Human beings! People are mammals too...
How mammals feed
Depending on what they eat, mammals can be classified into different groups.
Herbivores only eat plants and their teeth are especially designed for grinding. Horses, sheep and llamas are herbivorous mammals. Some very special herbivores are called ruminants. They swallow their food almost without chewing it, and some of it is digested normally, but some of it is stored in their stomach, and when they want to, they regurgitate it into their mouth to digest it again. Cows, giraffes and goats are ruminants.
Carne means skin or meat in Latin, and that’s what carnivores eat: the flesh of other animals. Their teeth are large and sharp for hunting and tearing at their food.
Carnivores that eat insects and other invertebrates are called insectivores,like these anteaters.
Omnivorous mammals feed on both meat and plants. Bears, monkeys and humans are omnivores: we can eat a tasty burger with lettuce and tomato.
So, let's remember,
Mammals are viviparous, and in their early stages of life they feed on milk from their mother’s breasts,They have lips and breathe with their lungs,Their body temperature does not depend on the environment they are in, and depending on their food sources, they may be herbivores, carnivores or omnivores.
Easy, right?

📦📏 Did you know that volume tells us how much space an object takes up? In this educational video for kids, you’ll learn what volume is, how it is measured, and what the cubic meter means as a unit of measurement.
In Primary School, the subject of Mathematics focuses on developing five key senses: the numerical sense, to work with numbers and operations; the measurement sense, to measure and compare magnitudes; the spatial sense, to understand geometric figures and their properties; the algebraic sense, to identify patterns and use symbols; and the stochastic sense, to interpret data and probabilities. Additionally, the socio-affective sense encourages a positive attitude toward mathematics.

I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: https://starbucks.app.link/derekmuller
Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.
Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.
A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.
Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.
It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

We compare some of the most popular languages in the world, what are the odds and probability of speaking certain language, which language has the most alphabets. Which language has the most words? How many words does English, Spanish, Arabic or Hindi have? What is the most difficult language to learn? What are the major languages of the world? We visualize the animated scale of alphabets, characters and words.
Disclaimer:
Only words of languages with over 20 million speakers are included otherwise the video would get too long. The only exceptions are the top 5. Thus apologies if your language is not included.
Only Alphabets with a usage of above 50 million, according to World Atlas, are included, with some exceptions. Video makes no distinction between speech, dialect and literacy.
Number referenced for words tend to be the largest dictionary that can be found online. Dictionary referenced in video. There may be bigger dictionaries though.
Usage or number of words may be outdated, but are often after 2010. More info in references.
There is difficulty researching between different formal definition of letters, diacritics and circumflexes, whichever probability and number given for the Alphabets are stated in the sources. There may be unintentional mistake, kindly comment if spotted.
