algy Posted July 24, 2012 Report Share Posted July 24, 2012 Would someone care to take a guess as to what these two photos are of ?. Quote Link to comment Share on other sites More sharing options...

asperity Posted July 24, 2012 Report Share Posted July 24, 2012 Atomic explosions (or the initial stages of)? Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted July 24, 2012 Report Share Posted July 24, 2012 Possibly grains of pollen as seen under an electron microscope? On further inspection may just be the start of an atomic explosion. Quote Link to comment Share on other sites More sharing options...
Dizzy Posted July 24, 2012 Report Share Posted July 24, 2012 Absolutely no idea but there does seem to be somthing that looks like a fence in the dark on the first one, and what looks like some sort of scaffolding type construction under the second one with again 'what looks like' 3 supporting ropes coming frot it or the 'thing'. Have you made the images black and whit Algy as for some reason I am thinking along the lines of a thermal image of something with the colours changed to grey scale. Maybe a hot air balloon on a big stick Quote Link to comment Share on other sites More sharing options...
algy Posted July 24, 2012 Author Report Share Posted July 24, 2012 Brilliant Asp!, The top image captures two common elements: the spikes (called "rope tricks") and an uneven surface shape. At this stage of the detonation the surface of the fireball has a temperature of 20,000 degrees, three times hotter than the sun's surface. At such temperatures the amount of thermal radiation (light) given off is so enormous anything it touches is vaporized ahead of the expanding fireball. The three spikes in this image result from the guide wires supporting the tower on which the bomb was located absorbing enough heat to turn into light emitting plasma. Because thermal radiation travels faster than the fireball, the spikes extend out ahead of it. The bottom photo was taken 0.001 seconds (1 millisecond)after the control operator pressed the "fire" button, the bottom photo also shows the tower that contained the 'bomb'. Trivia. The problem with getting a nuclear bomb to explode is bringing the fissionable materials together fast enough. Done too slowly they melt and vaporize before the runaway chain reaction can take place. The required rapid combination is achieved by surrounding the core segments with chemical explosives. While these explosives create the speed of combination required, they also create another problem: uneven detonation. To get a sphere of explosives to detonate all at once many detonators have to be used. These have to be timed to all go off at exactly the same time. Doing so required numerous problems such as variations in detonator reaction time, delays caused by detonator cable lengths, uneven local explosion forces caused by minor variations in the explosive and a host of other issues to be solved. Think of trying to wrap jelly with rubber bands and you get a feel for the problem. In theory it's possible, but doing it in the real world is a challenge. Making an atomic bomb is not the simple task it's made out to be in television thrillers. So folks no spies carrying nuclear bombs around in a brief case then!. :grin: Quote Link to comment Share on other sites More sharing options...
Dizzy Posted July 24, 2012 Report Share Posted July 24, 2012 Blimey Asp, Well done I should at least get 0.001 of a point though Algy for mentioning the word 'thermal' Quote Link to comment Share on other sites More sharing options...
algy Posted July 24, 2012 Author Report Share Posted July 24, 2012 Blimey Asp, Well done I should at least get 0.001 of a point though Algy for mentioning the word 'thermal' Yeh! right, Dizz you might have been referring to underwear. :grin: Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted July 25, 2012 Report Share Posted July 25, 2012 Only if she had been reading the Damart catalogue again :oops: Just finished posting this and there only appears to be one photo. what happened to the other one Quote Link to comment Share on other sites More sharing options...
Dizzy Posted July 25, 2012 Report Share Posted July 25, 2012 Ha ha you cheeky pair PS try specsavers Evils.... there are definately still two photos Quote Link to comment Share on other sites More sharing options...
