Dark Energy Stars

The picture of gravitational collapse provided by classical general relativity cannot be physically correct because it conflicts with ordinary quantum mechanics. For example, an event horizon makes it impossible to everywhere synchronize atomic clocks. As an alternative it has been proposed that the vacuum state has off-diagonal order, and that space-time undergoes a continuous phase transition near to where general relativity predicts there should be an event horizon. For example,…

Second Life Teaches Life Lessons

Another project, called Second Future, was undertaken by nine adults with cerebral palsy, and seeks to provide a forum in which they can share in the everyday personal interactions that most people take for granted. The group of nine, who share a single Second Life avatar known as Wilde Cunningham, get to experience being around other people without being judged. “Many of the real-world challenges are bypassed in Second Life,”…

Toothing

It‘stechnically possible, and it‘snot going to happen. That made it…

Ambush the White Rabbit

I fancy myself a pretty good sadist when it comes to generating shame and self-loathing in the tardy. If I spot a repeat offender in the hallway before class, and find that they’re not in attendance even after I’ve given them a comfortable buffer of time, I might push trashcans and desks in front of the door, constructing something of an obstacle course between the doorway and the desk so…
