    Top-secret tech

    the bomber is that fat plane that flies at a high altitude(not shore this is required) and has a lot of bombs on it...it drops the bombs and leaves...some models even have machine guns on them(witch I find very unusefull,on a bomber...even if you have a fighter in your back,you can't expect to...

    Top-secret tech

    are you talking about that bombardier that costs 2 bilion$ a piece? the only stealth fighter I know came out in 1991(when I was born,to answer the age part of the question...I'm 17)but I don't remember the name at the moment... either way,seems like I'm right...there is not a "diferent...

    Medical Reading or studying while listening to music

    I had a book about how to increase your learning abilities.sadley,my dog ate it:) but from what I remember,music composed by mozzart has this good efect,if you listen to it at a very low volume...it is called the mozzart efect! other tips are clear your desk of ANY objects besides the sheet of...

    Top-secret tech

    we all are familiar with this "top-secret" thing...some of us belive it,some of us don't...personaly I don't. but this question came to me,to sustain my point of view: if you want to research something that involves top-secret technology,don't you need to hire scientists that know in detail...

    why would you ingest something radioactive? I don't see ANY scenario when someone ingests an uranium pill or contaminated water...exept mabey for suicids

    Can radiation be seen

    well,I gues that having so many eruptions on your skin that you allmost look skinless is a prety visible efect...not to mention other signs like hemoragia...but this is at a relative high energy radiation...for a few thousand dolars you can buy yourself a chemestry elemental set,including a bit...

    Nuke radiations

    if by "we" you refer to the USA,then I'll have to dissapoint you...there was a pact that said that if you want nukes,you can't build more then 6...Rusia didn't signed the pact,thow...but thousands seems like a SF film

    Medical How to teach?

    yes,I forgot to mention not to repeat the same thing over and over again,couse people are going to fall asleep...say the same thing(things) in diferent ways and combined is the key. I'm starting to like this online-online response...you are the first member I catch online:)

    Medical How to teach?

    I see...very elaborate,I must say,but I'm concerned of one thing...the human has a long memory and a short one...the long one is the permanent one,the info can last from a week to some years without refreshing,but quite hard to stock in the info,and the short one that lasts for 3-5 minutes and...

    Computer tech

    it is natural to evolve,but I find it very unlikley to have double power at every 18 months(also,it's kind of strange to consider this a law,because it dosn't have a certan background,it should be rather a prediction) imagine you buy a car with a top speed of 100 mph...in 18 months a new car...

    Rockets VS misiles

    quoting chayced "–noun 1. any of various simple or complex tubelike devices containing combustibles that on being ignited liberate gases whose action propels the tube through the air" quote ended. seems like the dictionary is rong:) it's action does nothing(or at least burn something)...it is...

    Computer tech

    how come some computer parts double they're power once in like 18 months or so? it's kind of weird...alwais +100% and in 18 months or so...for example take the RAM memory...they came like this(in MB): 8,16,32,64,128,256,512,1024,2048,4096,8192! I didn't cheked,but the 16 GB RAM stick might be...

    Rockets VS misiles

    what is the diference betwin a rocket and a misile? from what I can tell,a rocket is something small,like a bazooka,or at most an anti-air rocket,and a misile is something huge,like a torpilo,or a nuke,or something realy big,but I'm not shore,and there might be several "oficial" diferences...

    Nuke radiations

    that dosn't seem a very smart solution,couse it will also give the enemy those few minutes...enought to finish his cofee,watch some TV,get a nap,meditate on the problem and send an anti-rocket rocket or something,so the bomb will not be that eficient... the solution here should be a faster...

    Can fire produce shadow?

    no,a fire doesn't cast a shadow! first,for a shadow,you don't need a light source and an opac object...you simply need not to have photons in an area(or at least very very phew of them,or if you do have a source of light,block it with an object...if you turn of the lights at night,you will have...

    Nuke radiations

    when the nuclear bomb was droped(dosn't mater witch),has the pilot of the bombarder been iradiated? his only chance is to get out of the radius,witch is realy huge,so you need the speed of the bombarder,the altitute at witch was released,and the mass of the bomb(not only the U,you need the cover...

    E=mc^2 and the nuclear bomb

    actualy,nuclear bombs don't use the nuclar force...they rather fight it...all that destructive force comes from the electric energy! you see,protons are all positive,so the electric force makes them get away from each other! luckely,there is the nuclear force that keeps them togeter,but the...

    Antimatter bomb vs tsar bomb

    I didn't cheked if the calculations above are corect,but I saw at discovery that a teaspoon of antimatter is equivalent to 100 hidrogen bombs...of course,I realy don't trust discovery anymore...in a magasine they stated that at - 30 kelvin degrees(yes,with the simbol of degrees) life can be...

    How to learn chemistry?

    either way,I see the key-word for chemestry is "practical" and it isn't worth to consider all those details,and chemestry works even if you look at the atom as an undevided ball,at least at my level... thanks a lot for posting...seems I've gatherd a lot of posts here:) any further comments are...
