Zothecula writes: Popeye gets his strength from downing a can of spinach and what works for him also works for solar panels. Researchers at Vanderbilt University led by David Cliffel and Kane Jennings have come up with a way to dope silicon with a protein found in spinach to create a more efficient "biohybrid" solar cell that produces substantially more electrical current than previous efforts and may one day lead to cheaper, more efficient solar panels.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
