Questions of a weird mind

Also, from another angle, stirring is more effective when it's sitting in a lump as the lump is dispersed.

Like evolution: Not perfect, just barely good enough to not become extinct.

I seem to recall seeing this same effect in spinning car wheels? Maybe I'm mistaken, but if not how does the blinking light explanation work here?

I don't think that was answered yet so I'll try: You will see this effect at night, with artifical light. Since the light uses alternating current it flickers with the frequency of this current (usually 50Hz-60Hz, depends on country). This flickering let you see the stroboscopic effect (as it is called) on car wheels.

Of course, this is functioning only if you use fluorescent light, light bulbs don't cause this effect because the frequency is too fast for them to stop emitting light.

Might as well ask this here...

Why do girls feel softer than guys? And no, the answer can't be moisturiser or female products, because I don't ever use them and am still apparently "Made of Softs!".

Now, on a more pratical level, you wouldn't actually like a guy to 'feel soft' while you're hugging him, right? Right.

When they say pictures of stelar nebulars and galaxies are real photos and not simulated, do they mean actual visible light photos, or just composites of infared, visible light, and gama-ray photos that have been colorized to make them visible?

I would have thought they mean they're real photos taken with a camera, regardless of what frequency of ER radiation that camera is detecting. They usually use the phrase "false colour image" to indicate they've changed the colours in the image because it was taken in a range of the ER spectrum that isn't normally visible, not "simulated".
