In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

During the middle ages, the majority of people lived in rural villages rather than urban cities or large towns.
But what was everyday life like in a medieval village?

Natural resources can be classified as renewable and nonrenewable resources. Natural resources can be classified as renewable or nonrenewable
A renewable resource can be replaced at the same rate in which the resource is used
Common renewable resources used to produce energy include,
Solar, like these solar panels converting solar energy into electricity. A nonrenewable resource is a resource that forms at a rate that is much slower than the rate that it is formed. Coal is an example. It takes millions of years to create coal and once it is used up it is no longer available
You can use CON to remember three popular nonrenewable resources.
This stands for
Coal
Oil
Natural Gas

We all know Charles Darwin's theory of evolution, right? Natural selection? But what about his lesser-know theory of evolution: sexual selection. Let’s talk about how animals like peacocks, whose eye-catching physical traits make them evolutionarily stronger even though their flashy looks make them more vulnerable to predators. Hint: it’s all about the chemistry.

This physics video tutorial provides a basic introduction into motion graphs such as position time graphs, velocity time graphs, and acceleration time graphs. It explains how to use area and slope to calculate the velocity, acceleration, displacement, and whether if the particle is speeding up or slowing down. It also explains how to determine if the velocity is increasing or if the acceleration is positive.

This is a math video lesson to help you with new math, math tricks, and or simple math questions you may have.

You've probably heard of the big bang theory at some point. But do you know what it actually is? In The Big Bang Theory for Kids, you will learn what exactly this idea for how the universe began came to be in the first place. You will also learn a little about our own galaxy and solar system along the way.

The big bang theory was first suggested by a cosmologist and priest named Georges Lemaître in the 1920s. He estimates that the universe started out as a single atom at the beginning of time. Rather than by an explosion, the universe simply started to expand in a fraction of a second due to matter and energy. Over time, the expansion slowed, but Lemaître and many other scientists believe the universe is still expanding today.

The force of gravity plays a huge role in everything when it comes to the universe. All the objects in space form when particles and gases from the universe's expansion pull together (through gravity). When small amounts of dust and gas pull together, planets form and start to orbit the star. Another force called dark energy or dark matter is also important. We don't have a lot of information about it, but scientists think it's what causes cosmos apart faster and faster.

We hope you and your student(s) enjoyed learning about this cool idea! If you want to learn even more, head over to our website and download one of our many free lesson plans about the universe, full of activities, worksheets, and more!

You have scored 7 out of 10 in your test. How does you teacher represent your marks? She uses a slash in between these numbers. But do you know what this slash actually represents?
Well it is a fraction. A fraction represents a part of the whole. The number on the top of the slash is called the numerator whereas the number at the bottom is the denominator. The denominator tells us the total parts whereas the numerator tells us the parts used.
There are five types of fractions - Like, unlike, proper, improper and mixed fractions. Let’s learn all the types in detail.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Mosquitoes are attracted to me and it's likely due to my genes.

Huge thanks to Prof. Immo Hansen and team: http://ve42.co/hansen

References:
Genome Wide Association Study for self-reported mosquito attractiveness:
http://ve42.co/MossieGWAS

The twin study showing correlated attractiveness is stronger for identical twins:
http://ve42.co/MossieTwins

Some things we know make mosquitoes more attracted to you:
Exercising, higher metabolism, higher body temperature, more body odor, being pregnant, type O blood, infrequent bathing, lactic acid, ammonia, acetone.

There are a number of folk remedies people believe protect them from mosquito bites like drinking alcohol, eating garlic, or taking vitamin B. These do not appear to provide any benefit in lab studies and in fact drinking alcohol is associated with increased mosquito activity because it causes blood vessels near the surface of the skin to dilate.

And apparently some of your attractiveness to mosquitos is simply genetic. This may be mediated through your immune system, which is what a lot of the genes identified were associated with.
