Multivariable Calculus on Khan Academy: Think calculus. Then think algebra II and working with two variables in a single equation. Now generalize and combine these two mathematical concepts, and you begin to see some of what Multivariable calculus entails, only now include multi dimensional thinking. Typical concepts or operations may include: limits and continuity, partial differentiation, multiple integration, scalar functions, and fundamental theorem of calculus in multiple dimensions.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more.

Grade 7th on Khan Academy: 7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)

One of the most famous swords was the Cutlass, used by naval men for centuries but made famous by pirates.
The overall build of the Cutlass made it extremely popular among seafarers in the 17th and 18th centuries.
As a short broadsword, generally around 28 inches in length, the Cutlass was ideal for use on ships, where space was limited.

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.

The Bicycle: Great inventions that changed history.

Hello friends! Welcome to a new HAppy Learning Video! Today, in our section great inventions of history, we’re going to get to know… the bicycle.

The bicycle is one of the most fun means of transport there is! Also, it is very ecological, and very healthy! Since when we ride a bicycle, we do physical exercise!
But… do you know who, and when the bicycle was invented? No? Well, let’s find out!

The truth is, that alike many other inventions, the bicycle was invented in various phases and it was various people who intervened in its evolution until reaching the bicycle we know today!

Here you can see the first bicycle in history! It was invented by Karl Drais in 1817 but, it doesn’t look a lot like contemporary bikes, it didn’t have pedals and you had to push it with feet on the ground.

In 1861, the Frenchman Ernest Michaux thought of putting pedals on the front wheel, but because it didn’t balance correctly, people fell off and his idea didn’t succeed. But it was useful so in 1873, James Starley, an English inventor, would manufacture a bicycle with the front wheel a lot bigger than the back one. Although the falls from so high up were dangerous, he made it easier to drive them, so in 1873, Thomas Steven commenced the first trip around the world. He took three years to finish it.

In 1885, John Kemp Starley, James Starley’s nephew invented a safe bicycle. Because it had breaks, and was a lot lower, falls were less frequent and less dangerous. Exactly, it was more secure… he had created a contemporary bicycle. From this moment on, the bicycle became famous throughout the whole world. And it started to be used for Cirque shows, to travel or just to do sports. But… the bicycle’s history hasn’t ended, there are still new bikes being invented, like mountain bikes, race bikes, electric or some which won’t move no matter how fast you pedal, like at the gym… There are a lot of curious bicycles, like all of these… It’s clear that the bicycle is an invention which runs smoothly! So everyone let’s ride a bike!

Many of California’s K–12 students are English Learners. Some have been in US schools since kindergarten, while others are new to US schools and may be refugees or unaccompanied minors. Laura Hill, a senior research fellow at PPIC, and Megan Hopkins, an assistant professor of education studies at the University of California, San Diego, summarize new research on academic progress among English Learners in middle school and high school and the factors associated with their successes and struggles.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

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.

This physics video tutorial explains how to solve complex DC circuits using kirchoff's law. Kirchoff's current law or junction rule states that the total current entering a junction is equal to the total current leaving the junction. Kirchoff's voltage law or loop rule states that the sum of all the voltages around a loop must add to zero. You need to be able to distinguish a voltage drop from a voltage lift. In addition, you need to be familiar with ohm's law when dealing with loop rule using kirchoff's law. This video contains plenty of examples and practice problems on KCl & KVl circuit analysis.
