From ancient Egyptian sarcophagi bathed in lapis lazuli to a synthetic pigment accidentally created in a lab that’s already being patented and marketed as ‘the bluest blue ever,’ blue is the rarest—and perhaps the most celebrated—color on earth. But why is it so hard to make and why are we are so enamored with it?
[Plant Pigment Analysis] Hello. Thank you for joining me today for today’s video on Plant Pigment Analysis. My name is Cynthia Sargent, and I’m the biology curriculum developer here at PASCO scientific. I want to show you how you can enhance a traditional lab activity using two sensors: a Colorimeter and a Spectrometer. A lot
If you look at a map of the US power grid, it looks like a spider web blanketing the entire country. It’s a patchwork that formed after communities that got their power locally were slowly stitched together to create a massive network. So could we scale that up even bigger? Could we connect the entire

Finally we are going to hear from Doug Kell, who is the CEO of the BBSRC, and he is going to just tell us about how we make sure that this report, which you’ve all got I hope, will influence the Research Councils’ thinking and where we go to next. Thanks very much indeed Robert.
EVERY physical variable (distance, time, mass, speed, energy, and so on) has units of measurement. For example, the agreed-upon international unit of speed (and of velocity) is the meter per second, abbreviated m over s. Sometimes international units are inconvenient. For example, if you happen to be speeding in the United States, you might need
