How do you know you’re real? Is existence all just a big dream? Has some mad scientist duped us into simply believing that we exist? James Zucker investigates all of these questions (and more) in this mind-boggling tribute to René Descartes’s “Meditations on First Philosophy.”
Is it possible to be scared to death?
The presentation was made at the Hawking Radiation conference, which was co-hosted by the theoretical physics institute, Nordita, and the University of North Carolina, on the campus of KTH Royal Institute of Technology in Stockholm. Nordita is driven by both KTH and Stockholm University.
Although one third of the population suffers from motion sickness, scientists aren’t exactly sure what causes it. Like the common cold, it’s a seemingly simple problem that’s still without a cure. And if you think it’s bad on a long family car ride, imagine being a motion sick astronaut! Rose Eveleth explains what’s happening in our bodies when we get the car sick blues.
Are video games good for you?
Turn water into wine! This simple science experiment demonstrates how fluids with different density can switch places. Fun to use as a magic party trick or as a demonstration for a physics experiment. Watch as the water switches place with the wine, because water has a higher density then wine. You could try using a playing card instead of the thin plastic spacer.
