Bacteria is not likely to leave a residue. Again; check with your neighbors.

The suit is pressurized and so makes bending/joint movements stiff. Then too, the guy is falling over a bar and the suit is connected to hoses.

Could be stuff in the lines from non-use after the last occupant vacated. Many water supply lines are copper. Also, many cities publish water quality test results that tell what all is in the water. You might check with other apartment dwellers to see if they have similar pot staining.

It could be useful in ballistics to know how long it will take a projectile to reach the target, particularly if the target is moving.

Yes, regardless of medium and yes the cooler will reach equilibrium with the hotter. Here's a wiki on heat transfer: >>Heat transfer

Green is an indicator of copper. What material is the pot made of? What is the source of your water?

Cross-post: To expand on Externet's succinct reply, heat flow is always from hotter to cooler.

Something! I always recommend Hofstadter, but as far as I know I have had no takers. A strange loop is a terrible thing to waste. I Am a Strange Loop

There is no generally accepted exegesis of anything in the Bible and it's a snipe hunt to look for such a thing. Proverbs 18:2 A fool takes no pleasure in understanding, but only in expressing an opinion.

That's the crux of the matter Mike. Your getting it has no bearing whatsoever on whether or not it is true. Clearly others do get it and yet you have the temerity to argue with them. After all this time and many threads it appears that you never will get it; just let it go.

There would be a slight gain without the drag of air, but a net loss in height of jump due to the weight of the spacesuit.

John, John, John...to quote another here, getting a straight answer from you is like herding cats. To herd cats, one must focus their Chi qí. Edit: Correct speeling air and add link.

I don't buy it, but as John pointed out you can certainly sell it.

This is what I was looking for, relative to an explanation. Now to find out if this actually holds any truth. Since the energy delivered to the target is a function of the mass and speed of/in the punch, then that explanation strikes me as clearly inaccurate. Energy 'reabsorbed by your arm' makes no physical sense here. The puncher does not gain any mass which leaves speed as a factor and how does one absorb speed?

I bow to your superior intellect in explicating the matter for us.

No WIFI. It's L830; not 830L as I said. Here's the specs: >COOLPIXL830 Back on topic, besides an angled swing showing up as energy not straight onto the target, heavy bags are usually suspended by chains and any upward force in a strike will make the bag jump up and so swing out less. All-in-all, I think the "instant recoil after a punch delivers a stronger blow" idea is a myth. Happy punching!

Just joshin' ya Sensei. But yes, the more energy directed into the bag the further it swings out. You find the nicest equipment! A bit off-topic, but if I didn't say elsewhere, I ended up getting a Coolpix 830L. It doesn't have the interval record but it has great macro, panaorama vertical & horizontal, and HD video. Thnx for putting me onto it. Probably add at least a 3rd camera directly behind the bag looking toward the puncher to detect any angle in the swing other than directly away from the puncher.

Your thesaurus link is a dead-end. Anyway, what is called for is a dictionary. Of these listed definitions, science applies the first three and the rest constitute non-scientific definitions/applications of the word. Dictionary: theory

Are you suggesting my suggestion was not a real experiment! That's a good addition however. I would also suggest having the camera positioned so that the entire puncher is in the frame so that it's possible to gauge the speed of the punch and any differences in stance or arm position.

I suggest taking some actual measurements rather than trusting your impressions. Put a scale with vertical markings on one side of the bag and a video camera opposite and on the other side of the bag and then deliver your blows from 90º relative to the camera's line-of-sight. Make multiple recordings and carefully review the results and report back. There is no physical reason to expect a quickly withdrawn blow delivers more energy, though there is a physical reason that a quicker blow does. Hammer

Erhm...that's suffix. That's the $64000 question.
