i'm not against smartphones in general, just the iphone.

i use it quite often actually. its good for quick 'back of the napkin' calculations if i'm responding to a post on the forum and i need a ballpark figure or soemthing to compare it to. it also allows you to link to your working for it and let the other user see for themselves. it only gets better as time goes on. in short, i love it.

ah forgot about neutrons(despite me just doing an asignment on neutron capture cross section)

yes you can have some particles that can exist in the same place at once, but not all particles. most importantly, the particles we are made of. also, when atoms get close enough to each other, they fuse. so everytime someone walks through a doorway that has already been used, KABOOM. although as there is no time, they would be thrown back by the explosion before they got close resulting in them never getting there in the first place ultimately leading to a paradox and internal inconsistency with the theory that there is no time. so, either you cannot walk through doors or there are more paradoxes than lost socks. so again you come back to the same conclusion, time is necessary. you either need it or something indistinguishable from it (in other words, you need time or time).

not really. you get cosmic radiation which can be iron nuclei. lightning won't really cause too many high ions. you might get some +3's and +4's but i seriously doubt anything more than that. anyway, the point is moot as electronegativity really only applies to neutral atomic/molecular species.

Alright then SFN. My old phone (a samsung D500) has decided that the battery is low even when on external power and the battery removed. swapping battery doesn't help either. as the only way to stop the alarm is to mutilate the speaker(and make it useless as a phone) i'm going to be getting another. so as my knowledge of mobile phones would be hard stretched to fill a post-it note i'm going to be asking you guys for recommendations. the requirements are:- -can make phone calls -can send texts -has bluetooth -has good battery life(current phone went a week and a half without recharge looking for similar or better) -cheap(-ish parents are buying so i can go above my usual miserly value) -some decent camera functionality(not necessary but would be a nice little bonus) Anyone who suggests an iPhone will be not so politely told to go do some very rude things with a tent-pole, porcupine, bucket of lard and a cricket bat.

no, a -94 charge would be impossible as the electrons would experience a repulsive force capable of ejecting them. a +94 charge is perfectly feasible as we have the good old strong nuclear force to counteract the electrostatic repulsion.

not only that but we have existing rocket designs that could do the job pretty easily. so it isn't a case of design a new one from scratch, but manufacture more of an existing one.

First off, i'm going to make a few comments about your posting style, please, don't take it as a personal attack or anything, just some suggestions that would make your posts better. 1/ you don't need to start off with 'REPLY:' we can see it's a reply and its a bit redundant and annoying. 2/ paragraphs. they are wonderful things indeed. a few little blank lines in your post would do wonders for the readability of the post. i'm not long awake and finding it exceedingly difficult to read you post. not because of content but formatting. i would be grateful if you introduced these changes to future postings. now, onto the analysis! alpha particle carry a large electric charge, they are moving fairly fast considering normal human experience, but not so fast considering radiation. they interact with nearly every particle the get within a few micro meters of. even gasses will slow them down. when they reach a solid such as skin, there's plenty of particles for them to interact with and lose energy to. and since the interactions are so strong due to the high charge, they lose all their energy very fast. not making direct particle to particle contact does not mean that there is no interaction. pretty much the same thing happens when you 'touch' something. the molecules in your hand aren't actually contacting the molecules of the surface but the electron shells are repelling each other from a distance. once it stops, yes. before that its moving too fast to capture electrons from stationary atoms into its orbitals. on its way how ever, it will dislodge a few thousand electrons from their parent atoms. well you can get a naked nucleus of any element really as the electrons don't contribute much to nuclear stability. so the nucleus of a greater atomic number element like uranium or so would be more electronegative. they are immensly destructive if they occur in living tissue. about 20 times more dangerous than other types of radiation. however, the dead skin you're covered in is dead. it can't form cancer as it doesn't reproduce or live. the only thing that could happen is with a truely immense alpha dose it could heat up enough to burn you.

40 frames a second. sounds an awful lot like you need a time component for the motion. i'm going to give you an example of why motion without time is somewhat absurd. lets take a door. there are two many people who want to use this door. now, in a universe with time, this is an easy situation to resolve, they all take a turn at going through the door at different times. now, in a universe without time they do not have to option of going through at different times so they'd all collide at the door(before the door depending on how many there are. the usual way people claiming there is no time get round this, is claiming that there is 'something' that behaves exactly like time in every description but they insist it isn't called time. which is equally absurd. so. the existance and function of doors(also chairs, tv's, cars, roads, tunnels, locks, keys etc.) pretty much proves that there is a physical phenomenon known as time.

no, not really. and it is far far from being the strongest acid

its not really an acid as it has a pH of 7 and hence neutral.

it still isn't a good definition, as oxygen can be the thing being oxidised

the top layer of your skin is dead, it is also thick enough to stop a ver large proportion of the alpha particle radiation. an alpha particle will not cause fission(paricularly in the lower atomic masses) because it will never get close enough to the nucleus to actually hit it. it will change its direction and velocity by virtue of an electrostatic repulsion and rip a few electrons off but it won't cause fission.

3 doesn't hold all the time. redox reactions frequently don't have oxygen involved at all. and example would be reacting sodium with chlorine. the sodium is oxidized and the chlorine is reduced. oxygen wasn't involved at all.

but we are not talking about another universe(and if there is an other one then you are misaplying the word universe) we are talking about this one. and in this one has time. and motion does require time by its very definition

stick your fingers down your throat and have a measuring bucket standing by to find out. i'm pretty sure you have the appropriate body parts to find out for yourself.

only if you eat it. its primarily an alpha emitter so as long as it stays outside your body and it isn't a critical mass then there isn't much harm it can do.

actually for quarks they looked at the different compinations of quarks(not just protons and neutrons) and done some fancy mathematics to derive the unbound mass algebraicly.

flashdrives already have an longer mean time between failure than mechanical harddrives. by an order of magnitude in some cases. it used to be they went down pretty quickly but that has changed. mainly due to advanced wear-leveling algorithms used in the controller and advances in the design allowing for more erase-write cycles to occur before failure.

its hardly disorderly conduct though. its not as if they done a drive-by on the guy at the window, the just gave their order in an unconventional and utterly benign manner. if the person taking the order didn't understand it, they could have asked for them to repeat the order in a more conventional manner and if they refused to do it then they should have been told to move on and that'd be the end of it. they weren't out to cause trouble, they were just copying a youtube video because they thought it was cool(and i have a similar viewpoint there even though i'm not really a fan of rap at all). the only person who did ANY harm was the person who called the cops on them. also, on the point of them holding up the line, i've seen people speaking normally taking far longer to complete an order. and you don't know if there was a line at all so you can't really make that assertion.

i don't see how that merits a 'but'. there isn't anything incompatible. i suspect that you may be confusing matter and mass.

and H2+O2 mixture has a higher energy state than H2O when the bonds are reconfigured to the lower energy state of H2O this energy is released and hence mass. before the energy is released it is in the form of potential energy. it is a ridiculously small amount of mass lost though. 5.3ng per mole of water produced or 0.294ng per gram of water produced.

what do you mean that proves what? have you got any solid numbers or just more numbers you arrived at by magic.

to determine the behaviour and performance of a gas seperation membrane when a novel type of filler particle is used. although it could be used for other purposes as well. none of this relates to the thread though. you came up with any calculations yet?
