Sequences A sequence is a series of multiple posts on Less Wrong on the same topic, to coherently and fully explore a particular thesis. Reading the sequences is the most systematic way to approach the Less Wrong archives. If you'd like an abridged index of the sequences, try XiXiDu's guide, or Academian's guide targeted at people who already have a science background. Benito's Guide aims to systematically fill the reader in on the most important ideas discussed on LessWrong (not just in the sequences). It also begins with a series of videos, which are a friendly introduction, and useful if you enjoy talks and interviews. If you prefer books over blog posts, Thinking and Deciding by Jonathan Baron and Good and Real by Gary Drescher have been mentioned as books that overlap significantly with the sequences.

Have conferences like TED, and the explosion of the "Idea Class" run out of ideas? (Flickr/TEDxJakarta) Back in 1986, a guy named Richard Saul Wurman put together a meeting. A conference if you will. It was part show and tell, part 18th century salon. The astounding quantities of discarded plastic that end up in oceans each year tend to concentrate in ring-like swirls of currents called gyres, yet most of it can be hard to spot—not because it’s not there in great quantities, but because it often takes the form of fingernail-sized microplastics. “It looks like pristine ocean until you tow your net through the water,” researcher Erik Zettler at Sea Education Association (SEA) said about the North Atlantic Gyre. “That’s when you find the plastic.” The presence of so much plastic debris at sea poses dire threats to the marine life unlucky enough to ingest small bits of it or to become entangled in nets or plastic bags. But recent research has also revealed some of the surprising ways a few resourceful marine creatures use it to their own advantage. For some species, the tiniest scrap of plastic can offer transportation across the open sea, or access to dinner, or even an assist in reproduction.

Bubble 2.0 Is Popping I've discussed Bubble 2.0 -- the new crop of social media companies that have enjoyed sharp appreciation in the private markets, often funded by Goldman Sachs (GS) -- numerous times before, observing how many of these companies have outlandish expectations, no profits, and a flawed growth strategy that focuses on user acquisition rather than increasing key metrics such as revenue from assets or revenue per customer. The companies that I lump into Bubble 2.0 are Facebook (FB), Zynga (ZNGA), LinkedIn (LNKD), Groupon (GRPN), Yelp (YELP), Zillow (Z), and Pandora (P); others in the IPO pipeline include Twitter, Foursquare, AirBnb, and Spotify. There are some signs, however, that the bubble is beginning to pop. This could be an opportunity for short sellers looking for a quick profit, or a sign for bulls to take profits and close their position.

Learning and Memory From song lyrics to former addresses, our brains hold a seemingly endless supply of information. How are we able to learn, store, and recall information with such ease? Brain cells undergo chemical and structural changes during learning. By changing the number, or strength, of connections between brain cells, information is written into memory. Ongoing studies are helping scientists identify how different areas of the brain work together to enhance memory formation and storage. This insight could one day guide new treatments for learning disorders and memory loss. 25 Killer Websites that Make You Cleverer It’s easy to forget that we have access to a virtually limitless resource of information, i.e. the Internet.
