Ignition by Sunlight [PDF]

Nature, 1883
WHEN driving along the Beaumaris Road on Tuesday last at half-past three, I observed smoke issuing from the top of one of the carriage lamps. I stopped to examine the cause, and found that the reflector had concentrated the sun's rays on the wick of the candle lamp and caused it to smoulder.

Materials structure–property factorization for identification of synergistic phase interactions in complex solar fuels photoanodes

npj Computational Materials, 2022
Properties can be tailored by tuning composition in high-order composition spaces. For spaces with complex phase behavior, modeling the properties as a function of composition and phase distribution remains a formidable challenge.

Sunlight and Culture

Journal of Economic Behavior & Organization, 2021
Abstract The effects of the individualism vs. collectivism cultural dichotomy on economic outcomes have been widely recognized in the literature. We propose and test the hypothesis that individuals and populations located in areas exposed long-term to more ultraviolet radiation (UV-R; sunlight) exhibit a greater degree of collectivism.

Using the Microsoft Excel ‘Solver’ Tool to Perform Non-Linear Curve Fitting, Using a Range of Non-Newtonian Flow Curves as Examples.

Applied Rheology, 2001
The Microsoft Excel ‘Solver’ tool is a very simple but powerful procedure, even in the hands of the mathematically disadvantaged. It has very good application for quickly fitting experimental flow-curve data to non-Newtonian flow models with any number ...
