Used khanacademy for learning SQL I think for my GCSE, pretty good site as I recall.

I use it a lot for revisiting things I should know. I have only looked at the math stuff yet, but that one is very good.

You find it on youtube as well.
:nice: Awesome Thaine. Thanks for the tip. Lots to learn here. I'll be a rocket scientist in no time once I pass the first test

Maybe the most important lesson there is, if you want to work as a scientist. The basis of the scientific method.

Alternatively skip all that and be a well paid job a clairvoyant or homeopathy practitioner because we all know the dead can circumvent the second law of thermodynamics and reducing an active component in a drug to 1:1000000000 makes it highly effective. Ooh, homeopathy? Step right this way, Sir.

Love it, especially the last one about the contact problem.

One of the best analogies I've read in a long time.


An Interactive Guide To The Fourier Transform
Home›Math, Popular›

The Fourier Transform is one of deepest insights ever made. Unfortunately, the meaning is buried within dense equations:

Yikes. Rather than jumping into the symbols, let's experience the key idea firsthand. Here's a plain-English metaphor:

What does the Fourier Transform do? Given a smoothie, it finds the recipe.
How? Run the smoothie through filters to extract each ingredient.
Why? Recipes are easier to analyze, compare, and modify than the smoothie itself.
How do we get the smoothie back? Blend the ingredients.

Here's the "math English" version of the above:

The Fourier Transform takes a time-based pattern, measures every possible cycle, and returns the overall "cycle recipe" (the amplitude, offset, & rotation speed for every cycle that was found).

codys lab pretty interesting channel he processes small amounts of materials to extract Iron gold silver
this video pretty cool, old school when people made things for their loved ones.
