To celebrate Leonardo’s 30th anniversary with MIT Press, a group gathered in Cambridge last November to consider legacy and futures at the crossroads of art, science, and technology. Participants reflected on how Leonardo at times exceeded expectations, overlooked or underestimated ideas, learned lessons along the way, and outlined emerging realities and altered futures on the horizon of the next several decades. The event served as a reminder that some conversations are less of a conclusive discussion and more of an ongoing exchange. In a sense, each issue of Leonardo adds to the discourse by engaging on the spectrum of legacy and futures, even as we are building both.In this first issue of Volume 56, Morteza Gharib, Chris Roh, and Flavio Noca explore the legacy of Leonardo da Vinci’s creative genius in attempting to visualize gravity as a form of acceleration. Looking back at this legacy also prompts questions looking forward regarding how creative visualization might accelerate the future.Da Vinci’s fascination with motion—how to capture the movement of water, clouds, falling hail, birds in flight—sparked imagination-fueled experiments and theories that precede by over a century the more precise equations of Galileo, Newton, and those who followed. His “equation of movement” drawings continue to raise fundamental questions about momentum: What moves us, how, when, and why? As an invisible force, gravity is only made visible by witnessing it in action, only visualized when things are set in motion, falling into their rightful place. What’s more, gravity is not neutral; gravity’s pull provides accelerated motion rather than constant velocity. Considering the “g” force as rate of change or acceleration makes me wonder what other invisible forces might be tracked or harnessed to accelerate change? How might the visualization of gravity reveal the possibility and potency of invisible forces as accelerators?In turbulent times, it is frighteningly easy to ignore invisible forces that abound and surround us, such as the power of human potential for imagination, inspiration, hope, trust, love. Yet these are exactly the times when it is most important to recognize and reinforce these forces as essential accelerators advancing the inherent human capacity for good. These unseen yet undeniable forces manifest in myriad ways through interdependent expressions of artistic creativity, scientific inquiry, technological innovation, collective generosity and hospitality. As the ultimate renewable energy resources, they generate momentum and means to develop the critical instruments, tools, and practices most needed today. These accelerators are essential to cultivate new and renewed support systems for humans to live and thrive on the planet. Like gravity, these accelerators are only made visible when activated. Our challenge is to magnify their magnetism that can actualize and optimize the human potential for positive change. The collaborative experiments and cross-disciplinary ideas of Leonardo’s community aim to do just that across our programs, partnerships, people, and publications, including the pages of this one. Leonardo continues to explore and expose living legacy, altered futures, and emerging realities, however hidden or entangled they may be.
