"One of our visitors asked why Spirals have their shape."

Cause at the center of spiral galaxies (like our own, don't forget that!) is a giant sucking black hole that will eventually eat the entire galaxy....tell them they have enough time to get their affairs in order.......unless the sun burns out first.......

"Where does gravity come from?" from a 10 year old girl. I told her that if she figured that out, she'd be famous.

But then I shifted into a brief explanation of orbits, and mass, and why the sun is at the center of the Solar System, and why the things we were looking at (moon and planets) were always "moving around".

I actually get a lot of questions relating to the mechanics of orbits - why we can't see Jupiter now ("hasn't risen yet"), why we'll be able to see it much better in a few months; how these planets, just like the sun, rise in the east and set in the west; why conjunctions are temporary and wonderful. They're just not used to thinking about it.

Oh, and minions - do you get those from the same place you get henchmen? Or is that a different franchise?

Minions are smaller and more compact...and not necessarily human.

Excellent question... and answer. It's important to acknowledge what remains unresolved... the origin of mass?

I think that what gets people engaged and questioning is related to the ideas that you can get people to think about. And that's what makes outreach rewarding for me.




Bill, I think you've hit the nail on the head here. Outreach is an informal thing for me, usually among those friends that will listen. Your presentations are bound to generate more inquiry.

Yes, considerably more portable than henchmen... wage and hour laws don't apply either, although they've got a heck of a union...

I was doing an event last night with probably 500 people looking at the moon and Saturn. We got the normal "what power?", "how much", "how far", etc.

But I got a question I've never expected, pondered, or ever thought existed.

"This thing has great resolution. How many pixels does it have?"

I was taken aback by this, and didn't know how to answer this, so I just told him how the optical path works, etc.

Anyone else ever get that one?

An entertaining question... sort of like: What is the meaning of X0? The world of digital cameras has got people thinking about resolution in terms of pixels... even where they don't exist.

I honestly think that he thought there was a video screen in the eyepiece or mirror, so I proceeded to show him how the optical path worked. It is an interesting question, though.

My wife, super fan of Despicable Me I & II, who's had her share of interesting questions as a high school science teacher and sometime telescope operator at the Grand Canyon Star Party, just said "You have to grow your own minions...That's what grandchildren are for."

Cool question. In this case, your EYE is acting in place of the camera, so the each individual receptor cell is like a pixel. If you assume you are only using the rods (non-color sensitive cells on your retina) in the dark, then there are about 120 million rods. If a megapixel is 1 million pixels, that is about 120 megapixels. :-)

Man that is real inspiration. I will have to remember that response ha ha.
Dawkins is a real piece of work, and the real deal no doubt.

My standard answer to "how much did this cost?" is "Less than a bass boat or a Harley".

Overheard one night:

How long did it take to build that? (large homebuilt truss dob)

Billions of years.....he then went on to describe how all the elements in the universe were created by stars.....it always kind of stuck with me,,,thus the little blurb in my signature.

What's the magnification of that telescope?

Answer: It's arbitrary. Magnification is meaningless. I can make it as high as you want but it won't be useful magnification.
