Spaced repetition is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect.

Tip: WordPress & Footnotes
StandardTo make linked footnotes [1], add the following (in text mode) just before your footnotes:
</pre> <h4 id="footnotes">Footnotes</h4> <pre>
Now you need to link each footnote number in the text by using the link of your post and suffixing it (after the /) with
#footnotes
To see an example hover your cursor over or click any linked number in the text and notice how the url of the post changes. It’s a manual labor but I think it’s sometimes worth it.

Tip: WordPress & LaTeX
StandardWordPress is known to support 
To embed equations using
$latex your-latex-code$
To change the size precede the last $ sign with &s=2 like this:
$latex your-latex-code&s=2$
where 2 is the size which could be any number (as far as I know). For example, the Schrödinger equation above is of size 2. It was generated using:
$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>&s=2$

Working backward to solve problems
StandardA while ago I stumbled on Farnam Street blog [1] somehow and I am glad I’ve followed this blog. It puts forth really interesting ideas based on the readings of the author. He attempts to “master the best of what other people have already figured out”.
Recently, Shane the author, shared a post [2] with a TED talk on inversion [3]. The summary of the talk is as follows
Imagine where you want to be someday. Now, how did you get there? Retrograde analysis is a style of problem solving where you work backwards from the endgame you want. It can help you win at chess — or solve a problem in real life. At TEDYouth 2012, chess grandmaster Maurice Ashley delves into his favorite strategy.
