Are Engineered Nanoparticles Dangerous?

We'll be tackling the risks of nanoparticles and other particles more fully when Risk Bites launches formally in November. But until then, here's a roller-coaster ride of a video on what might be important when thinking about the risks and benefits or nanoparticles - or any other particles for that

08 The Types of Chemical Reaction

The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b

Raising an Obelisk: An Engineering Puzzle

In this NOVA video, two teams test out two theories put forth by archaeologists to explain how ancient Egyptians might have raised massive obelisks to stable, upright positions. While only one plan works in practice, both attempts demonstrate that difficult challenges require careful planning. This
