The idea is that this is a truly halfbaked invitation to a
halfcon, in Brisbane, Australia.
Heads up for anyone in the Brisbane area on Tuesday 19
June, 2012. There will be a halfcon in the lobby at the
Brisbane Hilton Hotel.
Of course, this time may have already passed, in your part
of
the world, so you can think of it as a Heisenberg Halfcon, if
that is the case.

Ooooh, oooh! I think I can just make that one. You will recognize me as I won't be wearing a carnation in my lapel. [+] |
|
| |
Apologies, I won't be able to have made it. |
|
| |
I was there tomorrow, where were you guys? |
|
| |
They would have been being happy at the likely
participation of their online friends. |
|
| |
You'll be laughing on the other side of your face in around six
centuries' time when the Arabs have taken over Australia and
there really is a halfcon there. I have no explanation for their
adoption of Gregorian month names though. |
|
| |
I plan to be dead in six centuries from now. |

Nah. When it's 2012 in the UK, it'll still only be about
1957 in oz. |
|
| |
I'll make an effort to send some nutrinos that passed briefly through me in that direction. If I'm really extraordinarily lucky I might deflect one. |
|
| |
I'll also make an effort to pop some particles in and out of existence there that may or may not have any association with my person whatsoever. |
|
| |
Ah, you poor insubstantial and tiny person who is not
a neutronium sphere a parsec in diameter,
[RayfordSteele]. |
|
| |
Will Schrödinger be there? |
|

//'ll make an effort to send some nutrinos that passed briefly through me in that direction.// |

Hmmm.
Apparently the primordial neutrino flux is 3*10^12 (neutrinos per square centimeter per second.
Or 3*10^16 per square meter per second.
Presumably these are evenly distributed.
Consider a sphere with the surface area (in m^2) of the neutrino flux (per sec per m^2). Each square meter of the surface will pass a neutrino from that central square meter on average once a second.
Therefore, the range at which you can reliably emit a neutrino from a 1m^2 'source' to a 1m^2 target in a few seconds is:
sqrt(3*10^16/(4*pi))=2.4*10^15 meters |

UnaBubba, I'm sending you more neutrinos than you'll ever need. Use them wisely. |

We're sending you a cat, a detector and a radioactive source in a sealed box. Second class. Via Bulgaria, Tristan da Cunha and Solihull. Don't open the box, it will probably smell baaaaaad ... but you won't know, unless you open the box. |

_possibly_ fixed. Think I neglected a bracket in the written formula, so I put one in. I might have made other mistakes in the calculation (it took longer than I had to write the anno, so I was in a hurry). I've still not checked it properly though - hope to get back to it. |
|
| |
Do people from here meet up for halfbakedness or was this a one-off? |
|
| |
Usually we just meet in small groups and laugh about
those not in on the joke, [Phront]. |
|
| |
I can see why there aren't many. |
|
| |
There's a certain satisfaction in seeing someone prove me right :) |
|
| |
I wasn't there again, today. |
