My wife made one during Bush II that says, in Japanese:

"I sincerely apologize that my President is an asshole. I didn't vote for him."

I remember a fellow in an elevator glanced at it, did a double-take, and guffawed.

When we next broadcast Star Trek, I'll send you an invitation. It's the original... with commercials and fanzine readings! :) The proper experience.

In many ways, M-5 was the opposite of an AI. Its problem is that it had a personality and independent thought...transplanted from an erratic creator:

And yes, the power source for Europan life has to come from somewhereโ€”either below or above!

Sadly, it is not open to the public (though I usually sneak my friend Francois in)

BUT my classes at CSUSM are open to the public for seniors 55+ through the OSHER program!

James, would widespread adoption of fusion power on Earth cause an appreciable rise of global temperature?

I wonder if bringing extra signs, and having a sign with a call to action ("Honk if you..." on one side, and "Join me if...") might grow your group.

I hate this idea.

And while gerrymanders suck, on the other hand, they're brittle. If we can make a wave, they're easy to flood. That's the way to fight gerrymanders, not to make more egregious gerrymanders.

Is it kosher to say "my series"? :)

I got a review recently that said #TheKitraSaga would make a great TV/Movie adaptation...

My favorite? Rosel George Brown is my reflexive answer, but Katherine MacLean, Miriam Allen deFord, Idris Seabright/Margaret St. Clair, Evelyn E. Smith, Kit Reed, Zenna Henderson, Carol Emshwiller, Pam Zoline, Madeleine L'Engle, and Andre Norton are also competitors. :) #WomenInSciFi

Did you know that the history of women in science fiction goes straight from Mary Shelley to Ursula K. LeGuin to Octavia Butler?

Are there even any other women who wrote science fiction before 1980?

For me, it was that the majority of published Star Trek novels/short stories was by women.
