Screen durability and the distracting crease are the two biggest problems with foldables, so they are making a phone where a third of the screen is always unprotected, added an additional crease, and sharpened the radius of both creases. Hard pass for me (and most people), but this is more of a statement piece for their manufacturing and engineering prowess than a mass market product. Hopefully the advances they make will improve single fold devices.
Radiologist here. There are multiple safety zones (four to be precise) around the machine and extensive screening procedures are required to access the inner zones. The magnet of an MRI is always on and extremely strong. However, you need to be pretty close for it to pull a gun from your hands. Like, less than a few meters. That would be zone 4. He should never have been that close.
The button he pressed is called a quench. It’s for life threatening emergencies only. Think “patient trapped between the machine and a metal object.” It vents the liquid helium used to keep it superconductive and basically destroys the machine. There is a way to wind the machine down without destroying it in situations that aren’t life threatening, but it takes over 24 hours.
