Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Educational video for children to learn what senses are and how they work: taste, touch, sight, hearing and smell. The sense of taste allows us to identify and recognize the flavor of food. The sense of touch allows us to detect, identify and distinguish among the qualities of an object and the world around us. Thanks to the sense of sight we are able to see the objects that surround us. The sense of hearing allows us to hear sounds and the sense of smell helps us detect smells. All senses are related to different organs and each one of them helps us to understand the world and enjoy the things we like or identify potential dangers. This is a video compilation of the five senses for kids, perfect for elementary school.

Perhaps even more harrowing than the progression towards these new weapons, was the regression back towards the basic weapons from the past. In stark contrast to the advancing technology of the twentieth century, many soldiers who were stuck in the close-corridors of trench warfare found themselves back in the medieval era.

Aprende a conjugar verbos en español. Tiempo pasado, presente y futuro.
Los verbos pueden estar en pasado, presente o futuro según el momento en que sucede la acción que se relata. Así si la acción ha sido en el pasado se dirá diferente que si ha sido ahora mismo (presente) o en el futuro.
Los verbos también tienen "personas" como "tú", "yo, "ellos", etc. En este caso al ser un video para aprender español nivel principiante, todos los verbos están en primera persona, "yo".
También hay muchos tiempos verbales, en esta oportunidad vemos los básicos, pasado, presente y futuro.
Los verbos utilizado en esta clase son : Comer, hacer, poder, amar, decir, estudiar, conocer, dormir, correr, mostrar, olvidar, leer, apoyar, gritar, perdonar que son de los verbos más utilizados en el idioma español.
En próximos videos haremos más verbos, más tiempos y más personas.

In this video, we will learn how plants feed and how they are classified into four groups: algae, mosses, ferns and phanerogams.
Hello friends! Welcome to a new Happy Learning video.
Today, we are going to learn about the importance of plants, their main characteristics and also, their classification. Presenting… The plant kingdom!
You already know that plants can’t move from one place to another, as you can see in these images, the great majority are held to the ground by roots, but they fulfill the vital functions of all living things: they are born, they grow, reproduce and die.
As you can see in these images, there are many types of plants, but… Do you know how many types there are? Well, according to scientists there are approximately 9 million different species. Some are gigantic, like this tree, that’s capable of producing shade for 100 people, at the same time! Others are tiny, like this miniscule flower… but although they may be different, they all have something in common… they are able to make their own food.
Plants don’t feed off other living creatures, like animals do, but they make their own food, thanks to photosynthesis, a process that transforms sunlight and inorganic matter in their surrounding, into food.
Photosynthesis is super important for plants, but for all living things too! Because in that process they release oxygen into the world… and without oxygen, none of us would be here today watching this video. Are plants important or what?
Plants were one of the first forms of life that appeared on earth, thanks to their capacity not to depend on other living creatures to survive.
Their most predominant colour is green, and this colour is called chlorophyll, an essential substance to perform photosynthesis.
PLANT CLASSIFICATION
As we said, there are many types of plants, and we can classify them in four large groups to get to know them better: algae, mosses, ferns and phanerogams.
Algae don’t have roots, stems or leaves. They live in water, both in rivers and seas, and they are the simplest plants.
Mosses are also simple plants. They live on solid ground but need a lot of humidity. They don’t have roots to absorb water in the ground because they live in very humid and bleak places.
Ferns are higher plants and their body is divided into roots, which is where they absorb water from the soil, stem, which is where the water circulates, and leaves, that grow upwards from the stem.
Phanerogams, despite their name, are the most common plants, because they reproduce through their flowers. They are higher plants and their bodies are divided into roots, stem and leaves. Trees are an example that belong to this group.
Well, now we know a bit more about plants and their importance towards all other living things. So you know that we need to take care of them, and respect them.

Recommended video: 5 things you didn’t know about eyes
https://www.youtube.com/watch?v=KsdYjtdpZtE&t=5s
-----------
1 - Do you know what the difference is between seas and oceans?
The most important difference between seas and oceans is that seas are a loot smaller. and they belong, to the oceans. actually, they are a part of them; the seas, are the part of the oceans, which are closest to land. We all know that on our planet we have, 5 oceans: Atlantic, Pacific, Indian, Arctic and Antarctic. But… do you know how many seas there are? Well there are 57. and the largest are the Arabian Sea, the South China Sea, Caribean Sea, Mediterranean Sea and the Bering Sea.
2- Did you know that at the bottom of the sea, there are volcanoes, and large plains?
Although a lot of people think that the bottom of the sea is flat, it’s not true. Actually, the bottom of the Sea is like land, it has mountains, volcanoes, caves, great planes and even waterfalls!!. It’s so deep and big, that although it may seem incredible, there are many places where humans have not reached yet. Actually, 95% of the sea, remains unexplored. There’s so much to discover!
3- Do you know that the Everest isn’t the largest mountain in the world?
Well no! The largest mountain on Earth is in the sea and it’s called Mauna Kea. This inactive volcano, located in a Hawaiian island, measures from the sea surface to its tip, 4207 meters. But if we measure it from its base, which is at the bottom of the ocean, it measures ten thousand meters high, and if we compare this to the 8 thousand 848 meters of the Everest, they turn the Mauna Kea into the largest mountain in the world. What is true, is that the Everest, is the highest point on Earth.
4- What do you think we know more about? Planet mars or the oceans?
Well, although it may seem incredible, we know Mars’ surface more and better than the bottom of the sea. Human beings know very little about species which habitat the oceans, and there are still many to be discovered. It’s probable that most of these species are very small organisms but scientists believe there are still fish, and mammals which have not been discovered yet. Each year we discover a mean of 2000 new species.
5- Did you know that the sea is the biggest rubbish dump in the universe?
Yes, sadly, the sea has been used for a long time, as a dump, without realising oceans are the lungs of our planet. More than 50% of the air we breathe is produced at sea. The Mediterranean Sea,, is the most contaminated in the world, but sadly, most oceans are at an alarming stage. Plastics, pesticides , chemical substances, oil… all affect the sea’s health and living things within it. More than 100 thousand marine animals like penguins, whales, dolphins, turtles, fish and birds... die every year, only because of the plastic in the sea…
Please respect and take care of nature, don’t throw rubbish to the sea or rivers and always recycle. If we take care of the water, if we take care of the sea, we will make all living things live in a better world, cleaner and happier.
