Learn the difference between an endothermic reaction and an exothermic reaction.
Endothermic reactions take in energy and might be cold to the touch. Exothermic reactions give off energy and will sometimes be warm or hot to the touch.
At @MooMooMath and Science, we end our videos with kindness multiplies kindness. In each of my #shorts I like to tell a quick Kindness story in order to inspire myself and others to practice kindness.
Acts of kindness make a lasting positive impact on the people around you.

I denne lektion gives en grundlæggende introduktion til brøkregneregler. Vi skal se, hvorledes man dividerer en brøk med et tal.
We have just seen the first image of a black hole, the supermassive black hole in the galaxy M87 with a mass 6.5 billion times that of our sun. But what is that image really showing us?
This is an awesome paper on the topic by J.P. Luminet:
Image of a spherical black hole with thin accretion disk
Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235
https://ve42.co/luminet
Using my every day intuition I wondered: will we see the "shadow" of the black hole even if we're looking edge on at the accretion disk? The answer is yes because the black hole warps space-time, so even if we wouldn't normally be able to see the back of the accretion disk, we can in this case because its light is bent up and over the black hole. Similarly we can see light from the bottom of the back of the accretion disk because it's bent under the bottom of the black hole. Plus there are additional images from light that does a half turn around the black hole leading to the inner rings.
What about the black hole "shadow" itself? Well initially I thought it can't be an image of the event horizon because it's so much bigger (2.6 times bigger). But if you trace back the rays, you find that for every point in the shadow, there is a corresponding ray that traces back to the event horizon. So in fact from our one observing location, we see all sides of the event horizon simultaneously! In fact infinitely many of these images, accounting for the virtually infinite number of times a photon can orbit the black hole before falling in. The edge of the shadow is due to the photon sphere - the radius at which light goes around in closed orbits. If a light ray coming in at an oblique angle just skims the photon sphere and then travels on to our telescopes, that is the closest 'impact parameter' possible, and it occurs at sqrt(27)/2*r_s

LIGNINGER og PARENTESER: I denne video kigger jeg på, hvorledes man løser ligninger med parenteser. Du skal stadig isolere X på den ene side og alle talene på den anden side.
Udover at behandle parenteser, så kommer videoen ind på, hvorledes du lægger X'er med hinanden fx: 3x+5x. For at det ikke skal forvirre, så kan du istedet for X blot tænke på fx bananer: 3 bananer + 5 bananer = 8 bananer. Dette er en nemmere måde at lægge X'er sammen på.

Leaving earth to find new homes in space is an old dream of humanity and will sooner or later be necessary for our survival. The planet that gets the most attention is Mars, a small, toxic and energy poor planet that just about seems good enough for a colony of depressed humans huddled in underground cities.
But what if we think bigger? What if we take Venus, one of the most hostile and deadly places in the solar system and turn it into a colony? Not by building lofty cloud cities, but by creating a proper second earth? It might be easier than you think.

Welcome our new video: Alphabet for Kids | Learn Letter A | Let's Learn Alphabet. Subscribe to our channel: https://goo.gl/iG2Bdr
Teaching kids the alphabets are the first step to their academic journey. This is the base of their education and it needs to be very clear from the beginning. Children start showing interest in learning the alphabet at about 2 years of age. They are learning to talk at this time and they are willing to grasp new ideas, new sounds and a brand-new start at their academics.
The speed at which a child learns the alphabet varies for every child. While some learn it fast and very easily others might take some more time and would the repetitions of alphabets to finally learn them by heart. Just because a child is slow does not mean that he/she is not intelligent enough. Every child is intelligent in their own way, it is the responsibility of the parents and teachers to discover the abilities of the child and let him/her learn the way he/she can.
There are many ways by which toddlers can be made to learn alphabets easily and very quickly. For a child at the age as young as 2 years, it is the responsibility of the parents to teach the child at home because when the child goes for the school admission he needs to be able to recognize the alphabets, repeat them, match the uppercase and lower-case letters and identify the sounds of the alphabets.
1. The alphabet song
It is classic. Sing the song around the house. When you introduce the alphabets to your child in a song form it will be more fun for him/her. They will recognize the tune and gradually will start singing along and in this way, the alphabets will start to become a part of his/her memory.
2. Use alphabet videos
Videos are very effective when it comes to teaching the child the alphabets. Because with videos the child will be engaged with both of their senses, the sight, and the hearing. They will be listening to the song while watching the alphabets appear on the screen simultaneously.
With the help of videos, the child will also be able to recognize the sound of the alphabet that is appearing on the screen. He/she will repeat the same sound and will eventually the song will be learned by heart by the child.
The videos will also be more fun for the child because of all the colors and animations that are mostly used in the videos created for kids. The colors and the animations will attract the child towards them and he/she will not feel bored with it. Choose a video that is interesting, colorful and has some animations to keep the child engaged in it. The child must enjoy while he is learning the alphabets because if he/she does not find it interesting enough, they will probably give it up and will not be interested and teaching them would become very difficult.
3. Read the alphabet book daily
The alphabet book is another great way to make your child familiar with the alphabets. Make your child familiar with the sounds of the alphabets as well. If your child feels interested in books than it will be very effective but if the kid is not very interested in books, like a lot of kids are not, then videos will be your day saver because every kid loves colors and fun things appearing on the screen.
4. Use toys
There are many alphabets toys available in the market. This will be a very fun way of teaching your child the alphabets because they will be learning while they are playing. Most of the things that kids learn are the things that they use and experience while they are playing. And the good thing is that it stays in their mind. So why not make alphabets also a new lesson while playing?
The first lesson for your kid

What is globalization? Is globalization a good thing or not. Well, I have an answer that may not surprise you: It's complicated. This week, Jacob and Adriene will argue that globalization is, in aggregate, good. Free trade and globalization tend to provide an overall benefit, and raises average incomes across the globe. The downside is that it isn't good for every individual in the system. In some countries, manufacturing jobs move to places where labor costs are lower. And some countries that receive the influx of jobs aren't prepared to deal with it, from a regulatory standpoint. Anyway, Jacob and Adriene can explain the whole thing to you in 10 minutes.

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.
Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.
The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.
I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.
Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!
Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.
Thanks for watching my channel.
Today we are introducing a new area of philosophy – philosophy of religion. We are starting this unit off with Anselm’s argument for God’s existence, while also considering objections to that argument.

For many of us in the modern world, a conveniently located toilet that efficiently and safely removes our bodily waste is a luxury that we take for granted. If we were to step back in time, to approximately 2000 years ago, we would see that life for the ancient Romans was not always quite so easy.
