1: which pieces are warmer, which pieces are cooler, and are any pieces the same temperature as each other? 2: After the top pieces and bottom pieces have been touching for a while, will the two bottom pieces be the same temperature or different temperatures?

3: Explain how their temperatures will compare, and why.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
