General science teachers often claim that black objects absorb all light and white objects reflect all light. To demonstrate, they may ask students to feel the difference between a locked black car and a white one parked outside on a hot day. While walking out to the parking lot to test this, one might see desiccated earthworms on a hot, whitish cement sidewalk.

Sometimes people paint a dining room dark red (which can usually be accomplished with one coat of paint). A later resident may have to apply multiple coats of white paint to undo any reddish tinge. The surface of a white car does feel cooler than a black one, but is the thickness of the white paint (along with other properties) comparable? Does anyone have  experience with the process of painting cars?

Some general science labs use Leslie Cubes, and they seem to indicate only minor thermal differences (i.e., single digit percentages) for the color (black or a white) of a cube. Cake mixes seem to recommend similar slight reductions in cooking temperature when using black baking pans (as oppsed to shiny ones). How much of a temperature difference is there for a person sitting in a black  or a white car, a black- or white-shingled house.

Does loose black clothing in hot climates really produce noticeable cooling air currents?

Recently I have heard, from the new scientist mag, of a particle called a Higs Boson. I realise that it can be in more than one place at the same time. What I don't understand is, how is that physically possible.

Following the recent spell of cold weather, I noticed that there are still piles of dirty snow with sand or grit (but not salt) in them, but all the clean snow has melted.

The questions sort of has a rhyme to it. :) While talking to a friend of mine, I suddeny came to a dead end. Considering we have an infinite lenght of twine, how high will a kite go?

I have flown a kite with about a kilometre of twine attached, how much further can it go considering that domestic aircraft fly at about 30000ft?

Is this any different from two non-spinning objects colliding? For example take two spheres (made of eg. wood) x -> 1kg and y -> 2kg spinning with 100rpm and 200rpm respectively. Is there any other factors involved? A way to think about it may be to visualise two spinning tops colliding vs two spheres. By the way, how will friction be involved, and what will happen if this is done in a vacuum?

Is there any way that the effects of Quantum Spin Entanglement can be directly obseved?

Brownian Motion effects can be seen with the naked eye; you use a fluid suspension e.g. milk, and view it in direct sunlight, you can see the multi-coloured effects of the particles changing position. This changing 'speckle' doesn't happen with solids e.g. back of the fingernail under similar lighting.

Lasers, or other monochrome light, makes this effect more pronounced.

Even a single colour (red) LED lets you view the tracks on a CD (small magnifying glass helps) but you can't view the same pattern in ordinary daylight.

Is there any mechanism that lets you observe any of the effects of QSE?

From the smallest particle to the largest galaxy, and maybe even the universe itself, everything seems to be in a spin. What causes this spinning? Is it fundamental result of physical laws? How did it start? Can it be stopped?

After microwaving a plate of food for two minutes, when I removed the plate, I noticed a living, normal and healthy ant on the bottom of the plate.  Assuming I did not pick up the ant post microwaving -- something I am almost certain I did not -- how is it possible for an ant to survive being microwaved for two minutes?  Chiton exoskeleton?  Weird surface area effect?  Ants are from space a la Fred Hoyle? ;)

Any help is appreciated.

My childhood plan has been to become rich and famous so that I can then afford to become a space tourist and make a miniature world all of my own... however, it is possible that my dream is in fact impossible thus I pose this question in hope of rescuing myself from potentially wasting several hundreds of millions; if I took with me a sphere of dirt with a bar magnet through its middle to give it a north and south pole, and once in zero gravity gave it a little spin then threw a handful of iron filings at my miniature planet could I possibly create a tiny world with an orbiting ring like Saturn's?
