The physics of how the contents of a microwaved pastry can become “hotter than the Sun” is the subject of an entertaining and informative blog entry by Ethan Siegel. He looks at the physics of heating “microwave pockets”, those roof-of-your-mouth-scalding savoury treats that appeared on shelves in the 1980s. He explains why the outer portion of a pocket can be extremely hot, while the interior remains frozen – and why pockets often explode when heated through.
Siegel’s been a bit cheeky and republished this entry from 2009, but I suppose it’s timeless and I’m sure you can still buy microwave pockets somewhere! His blog is called Starts With a Bang and the entry is entitled “Throwback Thursday: The physics of hot pockets”.
As the crisis in the Ukraine drags on, scientists are beginning to worry about the effect it could have on scientific collaborations involving Russia and the West. Several websites are reporting that Russia is threatening to ban US astronauts from the shuttles that travel to the International Space Station (ISS). Indeed, the Independent quotes Russia’s deputy prime minister Dmitry Rogozin as saying that it would be possible for Russia to independently operate its portion of the ISS, while the US would not be able to do so. Indeed both toilets on the ISS are Russian, so it could get very messy up there!

Fire and ice will mix together in a sporting cauldron this Sunday. The Seattle Seahawks are taking on the Denver Broncos in the Super Bowl at the MetLife Stadium in New Jersey, and all weather forecasters agree that it’s going to be rather chilly. In fact, some have criticized the National Football League (NFL) for electing to play the game in a stadium without a roof, rather than opting to stage the match under cover. Bear in mind, the Super Bowl is the sporting event of the year in the US and people take it very seriously indeed. To address some of the concerns, The Huffington Post published this article to analyse how the mechanics of the game can change under cold conditions. The entertaining article considers everything from the reduced bounciness of the ball, to the increased propensity of helmets to break due to changes in material pliability.
