Hooke's Law vs. Ampere's Law
Hooke's law of elasticity is an approximation that states that the amount by which a material body is deformed (the strain) is linearly related to the force causing the deformation (the stress). Materials for which Hooke's law is a useful approximation are known as linear-elastic or "Hookean" materials.
In physics, Ampère's circuital law, discovered by André-Marie Ampère, relates the circulating magnetic field in a closed loop to the electric current passing through the loop. It is the magnetic equivalent of Gauss's law.

Hooke in my booke.
No disrespect to Ampere, in fact I would never have received an 'A' in physics with out using his law, but Hooke would take him.
Hooke's Law is simple, and is used in many primitive forms of weapons, bows and arrows, sling shots, and most importantly, the "Red Rider BB gun." Ampere quickly gets his eye shot out; followed by the other one.
From there it will have a sound track much like that of "The beating of a High School Science Teacher" by Adam Sandler.
I'm going to go with Hooke on this one also. Both for the reasons you mention and to stand up for laws that are 'useful approximations' in general.
But to give Ampere here proper due remember this - electricity kills from amps (named for Ampere), not volts. And, as you point out, Ampere's Law allows you to build coil guns 0 which rock hard core. But coils guns suffer from the same problem as Guass Cannons and Rail Guns - power supply/storage. So while Ampere is charging his capacitors, Hooke is filling his tender little hiney with arrows and crossbow bolts.
I didn't like Gauss, so I have no reason to like Ampere.
Outside of that, I'll stick with my practicality reasoning. Besides, anyone who knows me knows that I have spent hours firing bows and arrows, even if only virtually. Give props to the man who explained why they work!
Incidentally, I believe Hooke's Law explains why my mouse buttons and keyboard keys pop back up after I depress them. Hence, if not for the Law Hooke explains, we would not be having this conversation.
As for depressed keyboard keys, well, they probably just need more Prozac.
tommy, you are incorrect in your second comment of your double post. Hooke's Law describes how the depressed buttons recover, not why. Most keyboards and mice use polymeric springs,and not metallic springs. Metals bend due to bond stress causing distortions. To understand why buttons with polymeric springs recover you must look at entropy. In an over simplification engineers out there must love, as the polymer is distended the chains become aligned which decreases entropy, causing the material to try to recover it's original position. The end result is it's springy nature.
However, it is odd that entropy, which will eventually kill us all, gets rid of depressions. One would think it would just make things worse.
I call Hooke on this one. Seriously, who ever heard of someone being killed by a single Ampere?
Actually beanholio, you are partially correct. 100 milliamps across the heart is sufficient to cause cardiac arrest.
That said, the lack of oxygen to the brain is what causes death, not the current.
So, can one amp kill? I suppose that depends on how literal you fell like making it.
Thank you for the clarification, Badanswer. However, the interrogative was asking if you had heard (not read) of anyone being killed by a single Ampere, not what is or isn't possible. I learned this method of deduction from one of the greatest chemists of our time: Mitchell Hedburg. His experiments with hallucinogens and barbituates is legendary. Hedburg utilized the aforementioned method of deduction in devising a clever home AIDs test in which Hedburg asked his friend if he knew anyone with AIDs. If the friend answered "No" then Hedburg was confident that he was lacking the disease. How did he know? The answer lies in Hedburg's words to his friend, "and you know me, right? Cool."
Cool indeed. Hooke wins.
beanholio, I never disagreed with your final assessment of Hooke winning.
As far as 'hearing' vs 'reading;' in the vernacular reading can be regarded as "hearing of." Additionally, if I still read aloud like a first grader (not saying I do) I would both read and hear of such an item.
Additionally, some of your facts or spelling may be off. I do not claim to know all famous scientists, but have never heard of a Mitchell Hedburg. Mitchell Hedberg has an entry in wikipedia, but is silent on his chemic achievements (if any), focusing instead on comic achievements.
I apologize for any spelling, grammatical, or factual errors in my postings on this illustrious forum. I currently work a graveyard shift and generally post my responses at unreasonably early hours so my mental faculties aren't always running at top efficiency, i.e., my spell cheker is broken.
Additionally, it is a generally accepted fact by those who know me that I am stupid, which may also contribute to the inanity of any statements I may make.
Once again, Hooke wins.
