...Along with Raman Sundrum of Johns Hopkins University, she published two papers in 1999 that have changed how physicists think about the structure of space. Randall proposed that the universe has more than four dimensions (three of space and one of time) and that these extra dimensions could be infinitely large...
Randall has influenced string theorists, who also claim that extra dimensions exist. String theory is a model of physics in which building blocks are one-dimensional objects called strings instead of zero-dimensional particles like electrons...
...Until now, string theorists have accounted for the fact that we can detect only three dimensions by claiming that the extra dimensions are curled up into infinitesimal loops and thus imperceptible...
With branes, Randall discovered a way to explain how extra dimensions could be hidden and infinitely large. Because the math behind her theory works, theoretical physicists have paid close attention to her research...
...Gender Sensitivity for All In the interview with newly elected Liberian President Ellen Johnson-Sirleaf [Nov. 28], TIME asked, "Is there something extra you bring to the job as a woman?" She responded, "Sensitivity to human needs. Maybe that comes from being a mother and interacting with other women, many of whom carry the biggest burden in times of war and peace."
