Do you go to Princeton University by any chance?

I'll be there! Looking forward to it :)

Agreed, but wouldn't a true cloak of invisibility still be a good thing to have while fleeing? Hiding in a corner of your house would be stupid, since everybody knows that's where you live, but if the Death Eaters aren't quite sure what city you're in, it would be good to be able to walk into the supermarket without anybody recognizing you.

In Escalation of Conflicts

Fully two dozen different Charms must have been spoken, then, but no more invisible people showed up. One of them in particular made Hermione's heart sink; she recognized it as the Charm which had been listed alongside the description of the True Cloak of Invisibility, which would not reveal the Cloak, but would tell you whether it or certain other artifacts were nearby.

In Multiple Hypothesis Testing

"That eye," said Harry Potter. There was a strange fierce light in the boy's eyes. "That isn't any ordinary device. It can see right through my invisibility cloak. You dodged my Transfigured taser as soon as I started raising it, even though I didn't speak any incantations. And now that I've watched it again - you spotted all my Time-Turned selves the moment you Flooed into this room, didn't you?"

James must have known that it wouldn't be very long before Voldemort found Lily and Harry even with the Cloak, given Voldemort's legendary powers. Trying to hold him off despite this was still a better idea, as it would at least give Lily and Harry the chance to flee rather than hide.

The Potters did not know that Voldemort was after their son specifically, only that they were in general danger from the Death Eaters by being opposed to them and also active members in the Order of the Phoenix. At this time, they were hidden by the fidelius charm, which is some pretty serious magics: "As long as the Secret Keeper refused to speak, You-Know-Who could search the village where Lily and James were staying for years and never find them, not even if he had his nose pressed against their sitting room window!"

Voldemort only went for their son after Snape told him of Trelawney's prophecy, which was immediately after it was spoken, making very little time for McGonagall to inform Dumbledore and for the OotP to react. (Even supposing they could decipher the prophecy instantly.)

Also, the note from Dumbledore specifically says that James left the cloak in Dumbledore's possession before he died. (Maybe to prevent it from getting into Voldemort's hands.) This explains why the cloak was not available when then Potters needed it the most.

If the invisibility cloak is so good at shielding people from death AND the Potter/Peverell family is focused on defeating death, why didn't James put baby Harry and Lily under the cloak as soon as they knew Harry was a target?

Harry is going about his daily life under cloak w/ broomstick now; surely his parents--who spent more time with Mad Eye than Harry has--would appreciate the need for constant vigilance when Voldemort wants to kill your baby.

Looks great! I'll be there.

So I hear the Megameetup is now February 4th/5th.

I would be happy to speak about a topic in Neuroscience if people are interested.

I will be back at college on the 17th, in Radnor. I have a regular schedule, and can say right now that Thursdays and Sundays I will be busy every week. Friday and Saturday I am almost always free all day, but the rest of the week I get out of classes at 4, so I would be unable to meet earlier than around 5 (depending on public transportation).

I assume other people will come to this, so their schedules need to be taken into account as well, but a Friday or Saturday would generally be best for me.

I live in Philadelphia and I'm interested in meet-ups.
