The Fundamental Physics program began about three decades ago with several LTCMP experiments operating on the ground. After a couple of decades of preparation, four experiments eventually flew on the Shuttle in the 1990s in low Earth orbit (see Zeno, CVX, LPE, and CheX). Now six new experiments are being prepared for flight, and this program is supporting twenty ground-based investigations, several of which are theoretical studies. The six flight experiments explore the dynamic properties of liquid helium near its phase transition at the lambda point, dynamic properties of helium in various sorts of confinement (i.e., two-dimensional or one-dimensional confinement), the effect of a heat current on the phase transition, and scaling laws near a critical point (see the write-ups for DYNAMX, BEST, MISTE, and EXACT).
