It’s almost Hallowe’en an time for some costume ideas. How about a physics theme this year?
For other ideas, there is Sheldon Cooper’s Doppler effect:
The Heisenberg Uncertainty Principle: As soon as you arrive, hide in a secluded place and remain perfectly still. If anybody sees you, run really fast in a random direction.
The Pauli Exclusion Principle (Requires two people): Dress in identical outfits, and refuse to be in the same room with one another. If circumstances force you to be close together, one of you must stand on your head.
Schrödinger’s Cat: Wear an ordinary cat costume, but when you get to the party, go hide in a closet. When somebody opens the door to check on you, flip a coin, and if it comes up heads, pretend to be dead.
The Doppler Effect: Wear an outfit that’s blue in the front and red on the back. Answer questions from people in front of you in a high-pitched voice, questions from people behind you in a deep voice. Bonus points if you carry small bottles of helium and sulfur hexafluoride to inhale for the appropriate pitch.
Bell’s Theorem: Requires two people. Go to a party, stay on opposite sides of the room at all times, but use spooky Leverage/ Burn Notice earpieces and microphones to ensure that your conversation is perfectly correlated with your partner on the other side of the party. Alternatively, write down conversation topics in advance, and work off that script. See if the other guests can tell which you’re doing.
The Second Law of Thermodynamics: Trash the place like a coked-up rock star. Potential drawback: often mistaken for Charlie Sheen (or Keith Moon, if you want to skew old).
Quantum Information: Any time somebody asks you a question, reply with a superposition of all possible answers at the same time. Potential drawback: often mistaken for Mitt Romney.
Gravitational Time Dilation: Red shirt, blue pants. Go to a party in a multi-storey dwelling, set the clocks on the top floor back an hour, and when they throw you out, insist that the party hasn’t ended yet.
The Global Positioning System: Requires at least four people. Go to a party dressed like satellites, then stand on chairs in the corners of the room and yell out the time at regular intervals: “Nine-oh-five and ten seconds!… Nine-oh-five and twenty seconds!…”
The comments sections of both posts have some more great ideas.
The easiest costume would be a naked singularity. However, in some areas that might lead to incarceration, definitely limiting your event horizon.
