If they were around today, they would have smiled at the thought of our children and grandchildren gluing their noses to tablet computer and smartphone displays for hours on end … We panic when we are shown spectral power distributions for tablet computers, such as those for the Apple i Pad® shown in Figure 3. Compared to incandescent lighting or even the spectral power distribution of daylight, it is horrific! Television in the 1950s was a technology in its infancy, something that was only possible with the development of a phosphor called JEDEC Phosphor P4-Sulphide. ” If only our parents knew the hazards they were exposing us to (in addition to the cancer-causing cocktail of chemicals in our TV dinners and desserts).
You could always tell if your neighbors were watching television by the blue flickering light emanating from their living room windows. Yes, the “white point” color temperature of P4-sulphide phosphors was an eye-searing 11,000 kelvins. There is, of course, no relation between the technologies of monochrome CRT phosphors and phosphor-based white light LEDs.
In systems where methane forms rapidly, microbial methane is neither in internal isotopic equilibrium nor hydrogen-isotope equilibrium with environmental waters.
A quantitative model of microbial methanogenesis that incorporates isotopes is proposed to explain these results.
When these songs come on, White People look at each other and say "Awwww yeah" or "Hell yeah" and are compelled to sing along.
Sometimes there’s also a corresponding stupid dance move.
We demonstrate that clumped-isotope based temperatures add new quantitative constraints to the relative amounts of biogenic vs.
thermogenic gases in the Antrim Shale indicating a larger proportion (∼50%) of thermogenic gas in the system than previously thought.

If ever there were a candidate for “Most Hyped Technology” during the late 90s and the current decade, it’s XML (though Java would be a close contender for the title).Sources of methane to sedimentary environments are commonly identified and quantified using the stable isotopic compositions of methane.
