Educators From The United States

"As I depart, I must offer a few words of warning. The campaign against me was about more than one university and one leader. This was merely a single skirmish in a broader war to unravel public faith in pillars of American society. Campaigns of this kind often start with attacks on education and expertise, because these are the tools that best equip communities to see through propaganda."

"What the Gay controversy shows is how political judgment today is too often based on the identity of the messenger rather than the message itself. This inevitably warps the values and policies radicals pursue. Our politics should not be defined simply by the desire to show hostility to the right but by the strategies and norms necessary to build a more progressive, equal and hopeful world."

"First, as much as Gay has been depicted as a DEI crusader, I don’t recall her being one at the start of her career. I was pretty sensitive to such things and frequently annoyed by the progressivism and pioneering critical race theory that held sway at Harvard. But I don’t recall Gay saying anything that stuck in my craw. Even her much-discussed dissertation on black representation, as I remember, was less an ideological endeavor than an exhausted grad student’s attempt to use some econometric gee-whizzery to get the degree."

"Debate and the inclusion of diverse viewpoints and experiences, while essential for our work, are not always easy to live with. They can be a recipe for discomfort, fired in the heat of social media and partisan rancor. And discomfort can weaken our resolve and make us vulnerable to a rhetoric of control and containment that has no place in the academy. That is when we must summon the courage to be Harvard. To love truth enough to endure the challenge of truth-seeking and truth-telling. To love truth enough to ask Why?"

"Only if God is not in any sense contingent can one avoid regress posed in the query, who created God?"

"[T]he von Neumann machine would be programmed to explore the stellar system... and relay information... back to the original solar system..."

"Even if there were no planets in the stellar system... the... machine could be programmed to turn some of the material into an O'Neill colony..."

"[T]he information to manufacture a human being is contained in the genes of a single human cell. Thus if an extraterrestrial intelligent species possessed the knowledge to synthesize a living cell—and... experts assert... the human race could develop such knowledge within 30 years—they could program a von Neumann machine to synthesize a fertilized egg cell of their species. If they possessed artificial womb technology—and such... is in the beginning stages... on Earth... they could... synthesize members of their species... As suggested by Eiseley... these beings could be raised... by the robots... free to develop their own civilization..."

"[T]he problem of interstellar travel has been reduced to... transporting a von Neumann machine to another stellar system. This can be done even with present-day rocket technology."

"As the copies of the space probe were made, they would be launched at the stars nearest the target star. When these probes reached these stars, the process would be repeated... until the probes covered all the stars of the Galaxy."

"[M]aterials [to reproduce the von Neumann machine] should be available in virtually any stellar system—including systems—in the form of meteors, asteroids, comets, and other debris from the formation of the stellar system. ...[M]aterial in asteroids are highly differentiatied; many... are largely nickel-iron, while others contain large amounts of hydrocarbons."

"The payload of a probe to another stellar system would be a self-reproducing universal constructor with human level intelligence (...a von Neumann machine) together with an engine... travelling... within the stellar target system—[the engine] could be an electric propulsion system... or a ..."

"Hunter has pointed out that by using a Jupiter swingby to approach the Sun and then giving a velocity boost at perihelion, a solar system escape velocity... is possible with present-day chemical rockets... [M]ost other stars should have planets (or companion stars) with characteristics sufficiently close to... the Jupiter-Sun system to use this launch strategy in reverse to slow down in the other solar system."

"What one needs is a self-reproducing universal constructor... a machine capable of making any device... capable of making a copy of itself. Von Neumann has shown... that such... is theoretically possible, and... a human being is a universal constructor specialized to perform on the surface of the Earth."

"[T]hus... any intelligent species would develop at least the rocket technology capable of... a travel velocity ves of 3 x 10-4c. At this velocity the travel time to the nearest stars would be between 104 and 105 years. This... would necessitate... self-repair capacity... Nuclear power-souces would supply the power... If power utilization during the free-fall period was... low, even chemical reactions could supply the power."

"It is a deficiency in computer technology, which prevents us from beginning the exploration of the Galaxy tomorrow."

"Most recently, the attacks have focused on my scholarship. My critics found instances in my academic writings where some material duplicated other scholars’ language, without proper attribution. I believe all scholars deserve full and appropriate credit for their work. When I learned of these errors, I promptly requested corrections from the journals in which the flagged articles were published, consistent with how I have seen similar faculty cases handled at Harvard."

"This new... physical indeterminism was... discovered in the 1980s and is... a consequence of Gödel's Incompleteness Theorem"

"[I]t seems likely that a species engaging in interstellar communication would possess a fairly sophisticated computer technology. ...Sagan has asserted that 'Communication with extraterrestrial intelligence... will require... computer actuated machines with abilities approaching... intelligence'."

"In a deeply polarized nation, Gay achieved a rare feat: bipartisan agreement, with both liberals and conservatives blasting her performance before Congress and her failure to adequately address campus tensions inflamed by the war between Israel and Hamas. When Gay stepped down last week, she cited “racial animus” as a factor in the attacks against her. She took pains to defend her scholarship, largely playing down the corrections she submitted after the plagiarism allegations."

"[T]he eternal life assumption... implies... there must exist in this future (but in two precise mathematical senses, also in the present and the past) a Person Who is simultaneously transcendent to yet immanent in the physical universe of space, time, and matter. In the Person's immanent temporal aspect... changing (forever growing in knowledge and power), but in the... transcendent eternal aspect, forever complete and unchanging. How this comes about as a matter of physics will be described..."

"I shall assume that such a species will... develop a self-replicating universal constructor with intelligence comparable to the human level—such a machine should be developed within a century, according to the experts...—and... combined with present-day rocket technology would make it possible to explore and/or colonize the Galaxy in less than 300 million years, for an initial investment less than the cost of operating a 10 MW microwave beacon for several hundred years, as proposed by SETI..."

"As ves is of the same order as the stellar random motion velocities, very sensitive guidance would be required... not... an insuperable problem with the assumed level of computer technology."

"[A] von Neumann cannot become obsolete... instructed by radio to make the latest devices..."

"It is not lost on me that I make an ideal canvas for projecting every anxiety about the generational and demographic changes unfolding on American campuses: a Black woman selected to lead a storied institution. Someone who views diversity as a source of institutional strength and dynamism. Someone who has advocated a modern curriculum that spans from the frontier of quantum science to the long-neglected history of Asian Americans. Someone who believes that a daughter of Haitian immigrants has something to offer to the nation’s oldest university."

"Having now seen how quickly the truth can become a casualty amid controversy, I’d urge a broader caution: At tense moments, every one of us must be more skeptical than ever of the loudest and most extreme voices in our culture, however well-organized or well-connected they might be. Too often they are pursuing self-serving agendas that should be met with more questions and less credulity."

"Throughout this work, I asked questions that had not been asked, used then-cutting-edge quantitative research methods and established a new understanding of representation in American politics. This work was published in the nation’s top political science journals and spawned important research by other scholars."

"College campuses in our country must remain places where students can learn, share and grow together, not spaces where proxy battles and political grandstanding take root. Universities must remain independent venues where courage and reason unite to advance truth, no matter what forces set against them."

"My research marshaled concrete evidence to show that when historically marginalized communities gain a meaningful voice in the halls of power, it signals an open door where before many saw only barriers. And that, in turn, strengthens our democracy."

"The flurry of coverage resulted in not so much a clear articulation of alleged misconduct by Gay as a vague fog of ill will that carried stench of scandal. The media seemed assured that Gay had done something wrong: maybe it was about academic integrity, or maybe it was about the supposed antisemitism on campus; maybe it was the racist subtext, all but declared by Gay’s rightwing critics, that a Black woman who attained a position of superlative prestige and authority could necessarily not have done so by merit. The media followed all this as if any of it was real, as if any of it mattered, proving themselves willing to serve as outlets for a rightwing propaganda effort that is wildly cynical, demonstrably sadistic, and avowedly indifferent to the truth."

"The challenges, of course, are not unique to Harvard. At the top of the list, I’d put declining trust in higher education and fewer people understanding the value of higher education for both individuals and society. That’s an existential challenge for us as an institution. The silver lining is that there are many potential partners as we make the case for why what we do matters and how it contributes to making the world a better place and enables all of us to thrive."

"Betraying my bias as a political scientist, I’m really excited about what we can do around democracy. We’re at a moment where it’s important for those of us who are champions of democracy to help the world understand how to make democracies work: How democratic governance and democratic practices can actually — if well done — solve crises and solve people’s problems."

"The political polarization doesn’t help, but it is striking that the erosion in public trust is bipartisan. That should be telling us something, that there’s a broad-based questioning of the value of higher education. Yes, there are some elements that are being inflected by partisan politics, but this is pretty widespread."

"There are three things that I always look for. I look for a commitment to excellence, because that’s what it means to be at Harvard. I look for commitment to collaboration, because I believe that no one has a monopoly on insight — even if it’s in your area and you are an expert. And I look for commitment to the mission, because that’s why we’re all here. I expect that from any member of a team that I lead and collaborate with. From there, we get to the unique requirements of a position and the unique contributions or assets that an individual might bring to the role."

"The biggest takeaway from my own research is just how important it is for people to feel seen and heard. Even when they disagree, it is critically important for their values, interests, and preferences to be recognized by leadership and integrated into the thinking of leaders. That’s probably the biggest thing. That’s one of the reasons my starting point in any decision-making process involves trying to understand the perspectives of the various stakeholders around an issue. I do that not with the expectation that I can satisfy everyone, but with an understanding that those perspectives need to be part of the consideration I bring to any issue."

"I talked about the opportunity for Harvard to be more connected to the world by centering the most pressing challenges that the world faces as University priorities. For me, those include democracy and all the ways in which democracy is faltering around the globe, the climate crisis, and inequality, to name a few. Harvard has a lot to bring to the table for society’s urgent priorities. There are also “frontier” opportunities that Harvard is uniquely positioned to exploit."

"Family, friends, colleagues, students and postdocs, alumni, distinguished guests. I stand before you today humbled by the prospect of leading Harvard, emboldened by the trust you have placed in me, and energized by your own commitment to this singular institution and to the common cause of higher education."

"Tipler has been criticized... for mixing religion with science. ...also ...for making wrong scientific assumptions. ...[I]t appears that the is accelerating and ...left to itself, will never enter the phase ...a prerequisite for the scenario ...Tipler is certainly wrong on many points that will be corrected by future scientists. But dismissing him as a crank is... like dismissing Leonardo as a crank because his aircraft sketches wouldn’t fly..."

"I relate deeply to Tipler’s... concept that future technology may... resurrect the dead... by... "copying them to the future" and... allow myself to contemplate such possibilities. There may be a point where consciousness becomes a important factor in the destiny of the universe, where conscious beings develop the capability to choose and build the universe they want to inhabit, and invite the dead of past ages to join the party by copying them to the future. ...[T]his soft rationalist, high level and not detailed concept ...will, I hope, be detailed and realized by future scientists and engineers."

"The Physics of Christianity... received... bad reviews from very smart people like John Walker."

"[I]f the observed acceleration were to continue forever, the Theory would be refuted. But the expansion of life to engulf the universe is EXACTLY what is required to cancel the positive cosmological constant (a.k.a. the Dark Energy)..."

"In his enthusiasm... Tipler has neglected part of the Popperian lesson about what the growth of knowledge must look like. If the omega point exists, and if... created in the way... Tipler... set out... the late universe will... consist of embodied thoughts of inconceivable wisdom, creativity and sheer numbers. But... problem solving means rival s, errors, criticism, refutation and backtracking. Admittedly, in the limit (which no one experiences), at the instant the universe ends, everything that is comprehensible may have been understood. But at every finite point our descendants' knowledge will be riddled with errors. Their knowledge will be greater, deeper and broader than we can imagine, but they will make mistakes on a correspondingly titanic scale too. Like us, they will never know certainty or physical security, for their survival, like ours, will depend on... creating a continuous stream of new knowledge. If they... fail, even once... to increase... computing speed and memory capacity... the sky will fall in on them and they will die. Their culture... will be split by passionate controversies. ...[I]t seems unlikely that it could... be regarded as a 'person'. Rather... a vast number of people interacting... disagreeing. ...often ...mistaken, and many mistakes ...uncorrected for... long periods (subjectively). Nor... ever... morally homogeneous...Nothing will be sacred... and... people will continually be questioning assumptions that other[s]... consider... fundamental moral truths. ...[B]y the methods of reason, every... controversy will be resolved. But... replaced by... more... fundamental controversies. Such... is very different from... God... But... some subculture within it... will be resurrecting us if Tipler is right."

"The Omega Point Theory suggests that the particle physics Standard Model (SM) is sufficient to explain both [dark matter and dark energy]: the Dark Energy is just the currently uncancelled part of the positive cosmological constant, and the Dark Matter is just the Standard Model SU(2)_{left} field, coupled to the SM Higgs field. I was very worried when I wrote PHYSICS OF IMMORTALTIY that the entropy in the CMBR would make an acceleration in the collapsing phase of universal history impossible. I propose to solve this problem by claiming the temperature of the CMBR — currently "measured"... 2.2726 degrees — is actually... ! I show in a paper I put on the lanl data base (xxx.lanl.gov) last November that such an apparently ridiculous claim is possible, because any quantized gauge field in a homogeneous and isotropic universe would NECESSARILY have a Planckian spectrum, even at zero temperature! What the measurements of CMBR showing that it is Planckian... are really measuring... not the temperature, but the size of the universe. In my paper, I show how to convert the... "temperature" of 2.2726 into the size of the universe."

"I love this place. Harvard is where I found my intellectual home. It has nurtured and inspired me since I first set foot in the Yard. I am deeply invested, not only in what Harvard is today, but also in what Harvard’s leadership means for the future."

"Both of my parents, each on their own, left everything they knew in Haiti to forge new lives in the United States. And because they understood that coming to America was not enough, they eagerly sought college education—to ensure the future they wanted for themselves and for their family."

"Tipler uses the theological term 'omniscient'... but... The omega point will not know everything. The overwhelming majority of abstract truths... will be inaccessible to it as they are to us."

"Tipler makes use of a handy linguistic device... common in mathematical physics... misleading if taken too literally. ...[T]o identify a limiting point of a sequence with the itself. ...What he does not mean is that there is that there is a knowing entity literally at the end point of ... there is no physical entity there at all. Thus... the knows nothing, and can... exist only because some... explanations... refer to the limiting properties of physical events..."

"Tipler says, it will be omnipotent. But... this... is not absolute. ...[I]t is strictly limited by the available matter and energy, and is subject to the laws of physics."

"Tipler makes... additional assumptions—some plausible, others less so—which enable him to fill in more details of future history. ...[His] quasi-religious interpretation... and his failure to distinguish that... from the underlying scientific theory, that have prevented the latter from being taken seriously."

"Tipler makes the point that the science of cosmology has tended to study the past... of spacetime. But most of spacetime lies to the future... Existing cosmology does address the issue of whether the universe will or will not recollapse, but... there has been very little theoretical investigation of the greater part of spacetime. ...[T]he lead-up to the has received far less study than the aftermath of the Big Bang. Tipler sees the omega-point theory as filling that gap. ...[It] deserves to become the prevailing theory of the future of spacetime until and unless it is experimentally (or otherwise) refuted. (Experimental refutation is possible because the existence of an omega point in our future places certain constraints on the condition of the universe today.)"
