"Tell the chef, the beer is on me."

Die deftige Suppe mit dem gewissen Etwas - The hearty soup with a twist

Learnt an interesting thing today on this arabic course,

The original Arabic number system looked like this, the one we now use.

It was designed so each character had the corresponding number of angles to the number, so the number 1 has 1 angle, 2 has 2 angles, 3 has 3, 0 has none etc…

It is so obvious now, I’ve always assumed its one of those things that just is, with no logical explanation, but here it is, perfectly simple and satisfying

My jaw is legit on the floor right about now :D

OH MY LORD!!!!! I AM IN MATH NERD HEAVEN!!

“Let's face it; by and large math is not easy, but that's what makes it so rewarding when you conquer a problem, and reach new heights of understanding.”

Danica McKellar

As we usher in the start of a new school year, it’s time to hit the ground running in your classes! Math can be pretty tough, but since it is the language in which scientists interpret the Universe, there’s really no getting around learning it. Check out these gifs that will help you visualize some tricky aspects of math, so you can dominate your exams this year.

Ellipse:

Solving Pascal triangles:

Use FOIL to easily multiply binomials:

Here’s how you solve logarithms:

Use this trick so you don’t get mixed up when doing matrix transpositions:

What the Pythagorean Theorem is really trying to show you:

Exterior angles of polygons will ALWAYS add up to 360 degrees:

If you’re studying trig, you better get pretty comfortable with circles. Check out this visualization that shows what you’re really looking at when you deal with pi:

If an arc of a circle is the same length as its radius, the resulting angle is one radian:

Visualizing sine (red) on the Y axis and cosine (blue) on the X axis. The relative position of the circle is shown in black:

This shows the same thing, but a bit more simply:

Here’s how sine and cosine apply to triangles:

Cosine is the derivative of sine:

Tangent lines:

Flipped on its side, the shape begins to make more sense:

Converting a function from Cartesian to Polar coordinates:

Drawing a parabola:

The Riemann sum is the approximate area under a curve:

Hyperbola:

Translating that into 3D, you get a hyperboloid. Believe it or not, it’s made with completely straight lines:

Seriously. You can even make it do this:
