How magic?

Wired reports - again - about an "impossible" engine technology called Emdrive:

"The Emdrive is an electromagnetic drive that would generate thrust from a closed system — “impossible” say some experts. To critics, it’s flat-out junk science, not even worth thinking about. But its inventor, Roger Shawyer, has doggedly continued his work. (...) While the argument over the drive’s impossibility continues, so does the engineering work. The problem is that nobody wants to talk about it."

Reading this, two of Clarke's technology laws come to mind:
- When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
- Any sufficiently advanced technology is indistinguishable from magic.
