Did you account for air drag, or did you only consider gravitational acceleration?

I took an average pebble out my garden. It weighs 10 grams and has a mean diameter of about 20 mm. If we assume it were perfectly spherical with a drag coefficient of 0.47, travelling through air with standard density of 1.225 kg/m^3, and plug the figures into the formula for terminal velocity we get: sqrt((2*0.01*9.81)/(1.225*(3.14*0.01^2)*0.47)) = 33 m/s or 119 km/h. If we pipe that into E = 1/2*m*v^2 for energy, we get ~5.5 J or ~4 ft-lb.

Or in other words, I need Bitcoin to do something exciting.

Yuh I'm dead impressed gentlemand didn't run off to Southend with Arriemoller's £1.60 +p&p. He could have settled with a gypsy woman and rubbed crystal balls while she cackled. But no, he did a trustworthy thing that one time.

He actually asked me to pay when the paper arrived, so I could have taken the paper and run.
Although he's got my address so he might have come for me.
And the post knows how to fleece you, total cost was over £7

don't know way but I think your OK from gentlemand.....

yeah right I do remember he told me once he could only walk for 15 straight minutes so not to much danger

Perfectly spherical bullets are way different to regular bullets that end up tumbling as soon as they lose the rotational speed with a way higher air drag.

Much of the penetration of a regular gunshot is thanks to its rotational speed. That's why pipeguns are not that effective, even at very short distance, unless properly directed against unprotected vital points (neck, eyes, temple, etc).

To the mooooooon!!! weeeeeeeeee

I fucking need some moon now that I am again mortgaged! Weeeeeeee!

Yeah, there's people that have been sent a hitman for way less than that. Good that you somehow managed to pay in due time!

Now safely deleted from my PMs and since I can't remember what happened an hour ago your opsec is safe again. Even if baddies roasted me for hours I couldn't tell them a thing. Try to behave just in case as they may not believe me.

always loved this moment @the simpsons the most, just those strangle scene's

Fire in front of the dog.

that would have very good odds of seriously hurting it via ricochet/spall, and hurting it is worse than killing it.

i have no wish to harm any animal, much less kill it. if it looks ready to attack, fine, dead dog. but if its pondering the situation ("hmm.. is that thing good to eat?") scaring it off is fine by me. scaring and hurting it via spall so it suffers is not.

Well firing in the air has a chance of killing a human, even if a small one.

Look there is no polite solution to dangerous situations like that. Pick the one that has the least chance of harming humans, not other animals.

as i said, in that direction there is nothing but trees for several miles. literally. nothing. at all. i could say more but it would give too much away. i fly my drone out that way sometimes. a over mile out and its the most uninteresting scenery ever.

anyway in a semi populated area its a consideration. here? ill not worry. especially as warning shots are pretty rare. the odds of one of those very infrequent rounds hitting anyone are about as zero as one can get.

Let's go down the rabbit hole of debate, shall we. Let's dispel the delusion.

Bitcoin: mostly speculation
Use: store of value, (up to certain level) payment network

Ethereum: mostly speculation
Use: decentralised computing, USP less clear than Bitcoin

why don't you say that bitcoin is sound money and ethereum is not?

Current use case for ethereum is scam coins, and it is merely a lame attempt to provide something that it proclaims bitcoin cannot, when bitcoin would also be able to provide such use cases, if ethereum were not already occupying that space in a decent (albiet likely temporary) kind of way.

To the extent that it matters, such information is already embedded in the original tweet, misaligned whiteknight trolling fucktwat.

Yeah, right.       Looking for a bit of opportunism here, I see.   Showing your true pouty colours.

HAHA no just a silly way of we already know that for weeks

A 'pebble' falling from several kilometers (without any acceleration except for gravity) will kill you I think. At least that's what I remember my calculation of over a decade ago.

Did you account for air drag, or did you only consider gravitational acceleration?

At that time it would have lost all of its rotation and probably would be just tumbling with added air drag. A parabolic shoot on the other hand.... But still most probably not deadly... if it was so unfortunate to hit someone in the head/eyes/neck. Which is like an extremely small probability in itself. A hit to the body of person with clothes would probably just bounce (not without some moderate impact pain depending on clothes thickness) and not penetrate.

Sigh..we have to get ya'll some more edjumacation..just saying.

Out of the more than 500 shots fired from the test platform only 4 falling bullets struck the platform and one fell in the boat near the platform. One of the bullets striking the platform left a 1/16 inch deep mark in the soft pine board. The bullet struck base first.

Based on the results of these tests it was concluded that the bullet return velocity was about 300 f.p.s. For the 150 gr. bullet this corresponds to an energy of 30 foot pounds. Earlier the Army had determined that, on the average, it required 60 foot pounds of energy to produce a disabling wound. Based on this information, a falling 150 gr. service bullet would not be lethal, although it could produce a serious wound.

We could dive into Stokes Law or Reynolds numbers but I think I will just leave it with this.

I dont know about you but a 1/16 inch dent in my skull sounds pretty painful...if not immediately lethal.

From your own data:

- Most of the bullets did not even hit the platform. (What I said about human pobablation density).
- 4 hit (out of 500), but only ONE left a 1.5mm mark on wood?

So even in that rare case most probably not deadly even if a head hit (surely painful) and, according to your own data: "Based on this information, a falling 150 gr. service bullet would not be lethal, although it could produce a serious wound"

It would not even penetrate the skull. There is hair, skin, meat, and bones all of which would cushion that 1.5mm dent better than wood. A serious concussion? Maybe. A slight probability of a deadly concussion? Yeah, but very slight indeed.

Anyway, no, I wouldn't want that random "lucky" bullet hitting me right in the middle of my fucking head or, even worse, an eye

In other words an unacceptable risk.

Unacceptable? It depends. How much would would I get for you to fire 500 rounds straight up in the air and me standing in place waiting for the more than improbable non-lethal head hit?

P.S.: I have good hair, mind you.

You'd have to pay me for it. I know how americans love lawsuits. Besides it's not about you mister narcissist. It's about the people it actually does happen to, especially those who did not consent to random falling bullets. The more it's accepted the more people will do it the more people will get hurt.

Wear a helmet and shoulder pads, for the sake of science.

out in the wild west of BTC I have been reading many people of bought the DIP, sometimes with pray for me.... but nonetheless read some DIP buying post

cheers for them doing some smartmoney buying, also HM bought again, gives me joy (all WO buying gives me joy)
we must be on the greatest ride together brothers
