Finance and capital markets on Khan Academy: Interest is the basis of modern capital markets. Depending on whether you are lending or borrowing, it can be viewed as a return on an asset (lending) or the cost of capital (borrowing). This tutorial gives an introduction to this fundamental concept, including what it means to compound. It also gives a rule of thumb that might make it easy to do some rough interest calculations in your head.
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. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Imagine an ocean where water is constantly boiling, it’s boundless, there is no coast in sight. It stretches as far as the horizon, although this fact is evasive to the observer, because as far as the eye can see the horizon is constantly shrouded in dense fog. Thick clouds with not a chink between them hide a huge, but dim sun. Only negligible fluctuations in the level of light indicate transitions from nights to days and nights again. If it has stopped being pitch-dark and it’s deep grey all around you, it means sunrise. And deep down, under scores of kilometres of water, there lies a billion-ton core of scorching ice. This is what the unique and mysterious world of Gliese 1214 b must look like.

Tiananmen Square, in the heart of the Chinese capital Beijing, has been a place of enormous significance in modern Chinese history.
For seven weeks in the spring and early summer of 1989, it was the focus of unparalleled protests by students and workers against the political and economic system, leading to a brutal government crackdown and international condemnation of the communist regime.

How to memorize the periodic table 10X faster - Video 1. Start with the first 20 elements at https://www.memorize.academy/first-20-elements and then go for the entire periodic table of 118 elements at https://www.memorize.academy/m....emorize-the-periodic
How do you memorize the periodic table in the fastest and easiest way possible? You use the natural power of your visual memory.
We offer an easy way to memorize the periodic table. Memorization of the periodic table with our innovative animated video series takes just hours, so memorize the elements now!
Most people only know the typical techniques to memorize using your verbal memory – acronyms, acrostics, rhymes, associations and songs. Those techniques can be great for remembering small amounts of information, but they don’t take advantage of the dramatic improvements to your recall when you activate your visual memory.
We’ll begin by picturing a typical poster or chart of the periodic table. There are many small, colorful squares, each with a name, number and symbol of an element, and together they create a large irregular shape.
This image will act as an anchor in your memory, holding down the chain of images which link together all the elements.
Now we’ll take that colorful poster and attach it to the first element. Picture that poster of the periodic table and imagine it’s wrapped around a water hydrant.
Why a water hydrant?
1. Hydrogen
The 1st element in the periodic table is Hydrogen. Hydrogen sounds similar to hydrant and that’s how you’ll be reminded of it. Picture a water hydrant you see on the sidewalk. It’s short, stubby, red, and looks strong. The hydrant is like a little man with a small hat on top and stubby arms sticking out the side.
Imagine that hydrant with the chart of the periodic table wrapped around it. When you think of the chart of the periodic table, you’ll picture it wrapped around a water hydrant. Because hydrant sounds similar to hydrogen, you’ll know the 1st element in the table is Hydrogen.
2. Helium
The 2nd element is Helium. If you’re like me, when you think of Helium, you automatically think of a helium balloon. When you let it go, it’s the type that floats up into the sky. Now imagine an enormous helium balloon. Make it the size of a car and picture it attached to the water hydrant. Because the helium balloon is so big and has so much lifting power, it starts to lift the water hydrant up off the sidewalk. Together they slowly float up into the air and away into the sky. Now, when you visualize the helium balloon floating upwards, you’ll know the 2nd element is Helium.
3. Lithium
The 3rd element is Lithium. Lithium sounds a bit like “lithp”. People that have a lisp – a type of speech impediment – aren’t able to pronounce “lisp” and say “lithp”. Let’s pretend the large helium balloon has a lisp. It also has a small hole in it, causing the balloon to slowly deflate. Usually a balloon with a hole in it will make a slow “ssss” sound, but because this balloon has a lisp or “lithp”, it makes a “thhh” sound. Visualize the large balloon slowly deflating making a “thhh” sound. When you think of the balloon’s “lithp”, you’ll be reminded of the 3rd element, Lithium.
4. Beryllium
The 4th element is Beryllium. If you say Beryllium slowly, it sounds like “bee really yum”. Picture your slowly deflating balloon. Imagine an enormous bumble bee lands on the balloon. The bee is the size of a football and has bright yellow and black stripes and buzzes loudly. The bee licks the balloon to have a taste and says, “that’s really yum!” It really likes the taste of the balloon. When you picture the bee licking the balloon, you’ll think, “bee really yum”, and be reminded of the 4th element, Beryllium.
5. Boron
The 5th element is Boron. We can break up the word Boron into “bore” and “on”. The word “bore” can mean to drill a hole. Picture now the bee, after tasting the balloon. It uses its stinger, pierces the balloon and starts to spin around in a drilling motion. The bee has landed on the balloon, tasted it, and now it’s started to “bore on” the balloon. When you picture the bee begin to bore on the balloon, you’ll remember the 5th element, Boron.
