Max Planck, one of the Twentieth Century’s most eminent physicists, observed, "An experiment is a question that science poses to Nature, and a measurement is
David Gerrold, a prolific American author, and screenwriter, summarizes the progress of the last 120 years when he observes, “In the 20th century, we had a
Semiconductor technologies are critical to U.S. economic and national security as they are essential to modern life in communications, healthcare, energy, etc. and also underpin many emerging technologies like quantum, artificial intelligence, high power electronics and advanced wireless (6G+). The
Low Reynolds number swimming, or motion through a viscous fluid, is a technique at which nature is adept. Bacteria, protists, and algal cells live in a regime where viscous effects dominate inertial ones. As these microscale biological swimmers move, they perturb the fluid around them, affecting
Intended impact: Cell behavior is powerfully modulated by local extracellular cues. However, the number of parameters that affect cell behavior is large, and include soluble signaling molecules, dissolved gases, the chemistry and mechanics of the extracellular matrix, and the proximity and behavior
