Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
A parlor-trick mystery explained at last.
- Two grape halves heated in a microwave produce light-emitting ionized gas, or plasma.
- The grapes collect and trap microwaves whose energy eventually bursts outward.
- The discovery could lead to passive microwave antennas.
Japan looks to replace China as the primary source of critical metals
- Enough rare earth minerals have been found off Japan to last centuries
- Rare earths are important materials for green technology, as well as medicine and manufacturing
- Where would we be without all of our rare-earth magnets?
Recipe for awe: Coat one egg with Starlite. Blast it with a ridiculous amount of heat until charred black. Crack it open.
- A professional hairdresser and amateur chemist invented an unbelievably heat-resistant coating called Starlite.
- Military applications brought governments running, but the inventor's odd negotiating style ruined discussions.
- Was Starlite lost when he died, or had it already been stolen?
Be glad your name isn't attached to any of these bad ideas.
- Some inventions can be celebrated during their time, but are proven to be devastating in the long run.
- The inventions doesn't have to be physical. Complex mathematical creations that create money for Wall Street can do as much damage, in theory, as a gas that destroys the ozone layer.
- Inventors can even see their creations be used for purposes far different than they had intended.
