Support for bold thinking and unconventional ideas comes from the Project X Fund, which provides seed funding to engineers who wish to pursue projects that may be outside their formal areas of expertise or are too speculative to attract conventional funding. The fund, established by Lynn Shostack in memory of her late husband, David Gardner ’69, has supported research ranging from an exploration of techniques to sterilize hospital rooms to the development of an idea for playing realistic three-dimensional sound from conventional speakers.
