Unknown green insect
What is this insect? Which species, family, or order? The photo was taken in Gyeonggi-do, South Korea. -- Kjoon lee 03:24, 1 September 2006 (UTC)

If an injured swimmer was to drown and the red blood cells found in the lungs were swollen and had burst, did the person drown in fresh water or sea water? Given that the tonicity of sea water is greater than that of the cytoplasm of blood cells , and the tonicity of fresh water is less than that of red blood cells, explain how you reached your conclusion. What process has occured in this situation? thanks Johanna
Difference between PRECISION & ACURRACY?
What is the clear-cut distinction between precision & accuracy?
- Accuracy and precision. Weregerbil 12:58, 1 September 2006 (UTC)
Kid in a natural history museum: "Hey mister, how old is that dinosaur ?"
Guard: "200 million and 8 years old."
Kid: "You mean 208 million years old ?"
Guard: "No, I mean 200 million and 8."
Kid: "But how do you know so precisely ?"
Guard: "Well, it was 200 million years old when I started working here 8 years ago, so..."

Should this one be on the language RefDesk, Stu? :) Loomis 20:57, 3 September 2006 (UTC)
Another example: My chemistry teacher said that 1 litre and 1.00 litre of a particular liquid mean different things. The reason: 1 litre meant was that you had between 0.5 and 1.5 litres. 1.00 litres actually meant that you had between 0.995 and 1.005 litres. Maybe precision is whether you use 1, 1.0 or 1.00, and accuracy is whether you measure it to be 0.997, 1.001 or 1.003? -- Chuq 10:18, 6 September 2006 (UTC)
Cattle in a feedlot
I know that before slaughter, many cattle are housed in a feedlot to be fattened up. I would like to know about how long an animal will typically stay in the feedlot. ike9898 13:08, 1 September 2006 (UTC)
Acetone as an additive for gas and diesel?
I read that adding minimal amounts of acetone to gasoline and diesel would increase mileage considerably. My question is if that is really the case. Also, of course, the car should not get damaged if one were to do this (especially the catalyst). Last but not least, would this increase, decrease or not affect exhausts at all? Thanks for your answers, RichiH 13:25, 1 September 2006 (UTC)
If there are plastic parts or hoses which degrade, soften or dissolve in acetone but not in gasoline, you might be in for some expensive repairs. As an analogy, I had a 1970 GM engine which worked great until in the 1980's they started adding alcohol to gasoline. The alcohol ruined the plastic float in the carbureter and required replacement of the carb. And doesn't acetone react with copper? Gasoline is for burning in engines, alcohol is for drinking, and acetone is for removing nail polish. Edison 17:06, 1 September 2006 (UTC)

Article in Dec 2000 Cleo
I am looking for an article you had in Dec 2000 Cleo titled FLEX by Sam Murphy. It was four pages long and was about exercises for deep abdominal muscles. If there is anyway you could forward me a copy or put it on your website I would be most grateful. Thank you Ruth Kelly, Ireland.

mosquito
what does a mosquito have instead of blood is it hemolymph like all other insects?or anything else?--hima 13:56, 1 September 2006 (UTC)hima

Petrol additives
Is there anything that can be added to unleaded petrol to improve fuel consumption in a car with an engine management system?
Could it be my EMS sensors not working correctly?--Light current 15:51, 1 September 2006 (UTC)
Well, additives do reduce gasoline consumption in that they burn themselves, providing some fuel. So, if you add a pint of fuel additive to a tank of fuel, you might reduce the fuel consumption by up to a pint. Thus, they aren't lying when they say their additive "reduces gasoline consumption", they are technically correct. Of course, the cost of the additive greatly exceeds the cost of the saved gasoline, that part they don't tell you. StuRat 00:49, 2 September 2006 (UTC)
World spin
Ive often wondered what originally gave rise to the rotation of the earth and what its rotational energy would be. Any one know?--Light current 15:12, 1 September 2006 (UTC)

Can for example a cat become pregnant from human sperm and vice versa (a woman from horse)? --Brand спойт 16:55, 1 September 2006 (UTC)
Also supposedly lion and tiger. What about primates? Gorilla/chimp/orangutan combinations? Horse/zebra? Edison 17:11, 1 September 2006 (UTC)
I see a pattern emerging here. First, there was no precise definition of planet until last week (and it's still not fully accepted). Now, you're telling us there's not even a precise definition of species. Before we go any further, is there anything else the scientific world wishes to 'fess up about?

Citric Acid
Would diluted citric acid kill sperm?
Err...Part two; would citric acid kill a yeast infection?
Moon moons ?
Does any moon have it's own natural satellites ? I would expect they would, unless tidal forces from the planet would cause their orbits to be unstable.
If there are examples of moon moons, how about moon moon moons, etc. ? (Has the word lost all meaning yet ?) :-) StuRat 20:49, 1 September 2006 (UTC)
What conditions would be needed to have a stable moon moon ? Perhaps a huge planet/failed star at an extreme distance (say 40 AU) from the main star could have a moon at an extreme distance from it (say 1 AU), and a moon moon around it that would be stable (being far enough away from gravitational tidal forces of the planet and star) ? StuRat 00:34, 2 September 2006 (UTC)
Just to qualify everything... in the approximation that the moon's orbit is circular, then you can prove mathematically that certain orbits around the moon are stable, since they are completely encircled by the zero-velocity curves of their Jacobi integral. Such protective curves go all the way out to the nearest Lagrange points. So you don't have to worry about the planet pulling the particle away f
