The Final Countdown
Within one second of the detonation, a 20 pounds per square inch (psi) overpressure will be generated out to a distance of 0.4 miles from the Empire State Building. Everything in this circle is utterly demolished. Those within this circle will be exposed to sudden pressure effects that destroys lungs and ear drums, shrapnel from nearby objects, and a thermal emission of such intensity that immediate death results.
488 nm: A Review of FACS Technology and its Application in Biological Research
Fluorescent imaging depends on the physical principles behind the scattering of light. In a typical fluorescent microscope, a laser, usually of argon, shines through a sample at a wavelength of 488 nm. The sample, in turn, fluoresces according to how it was stained. Certain cells, and often even specific cellular structures, can be resolved, which results in a fluorescent image that is reflected into an optical lens or screen for visual analysis.
