After a longer than expected summer break, we bring you the seven best popular science videos of the last two months. Actually in the next few episodes you can expect videos older than a week, as two months' time is way more than we could cover in just one episode.

Computerphile: what does entropy have to do with information? This video may not be the most spectacular way to present an amazing new channel of Brady Haran, but I kept coming across videos about entropy, so it has become kind of like a theme. Sixty Symbols explains how entropy is the basis of our notion of past, present and future, and how the understanding of entropy is connected with the Big Bang. At the same time Crash Course! also had an episode on entropy.

MinuteEarth: the ecology of craft beer and microbreweries.

Sixty Symbols: the physics of people moshing at heavy metal concerts. (And here's an intro to ideal gases in this, related Crash Course! Chemistry video.)

TED-Ed: do you really wanna live forever? TED-Ed's 6 episode series about superpowers gives you a few sobering things to consider, if you're dreaming of invisibility, flying, being a giant, super speed, super strength and immortality:

Numberphile: 1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1...=

Veritasium: how does a quantum computer work? Two additional videos were made by 2Veritasium to further explore this topic: how does a transistor work and what is spin in quantum mechanics?

Smarter Every Day: Smarter Every Day packed their high speed camera and went on a journey to the rainforest to make videos which simply blow your mind off: they filmed dragonflies taking off, they made ants carry their sign, they investigated the secrets of a strange cocoon with the help of a butterfly farmer, and they bumped into this heap of caterpillars moving in a jaw dropping way:

Vihart: this is quite enough to watch so far with all the extra links and all, but here's a bonus video for the two months break. Let me know in the comments what's your take on this brilliant philosophical piece!
