Astrophysics for People in a Hurry

Astrophysics for People in a Hurry
© 2017 Neil deGrasse Tyson
200 pages



Astrophysics for People in a Hurry is exactly what it says on the tin, a brief cosmological primer that presents the basics of cosmology, explains the ways we are continuing to learn about the cosmos, and ends with a Saganesque hush meditating on what the cosmic perspective has to offer. Neil deGrasse Tyson is an active science popularizer, the creator and primary host for StarTalk Radio, which has grown beyond a podcast to become a video series and book – not to mention his day job as director of the Hayden Planetarium in New York City.

Astrophysics is a review of what is known about the big picture, and avoids string theory, m-theory, branes, and other things best considered by people not in a hurry. Tyson does include a section on dark matter and dark energy, however, since the math of our current model of universal expansion doesn’t make sense without including them . Tyson is quick to defend against the idea that ‘dark matter’ – accounting for the detected weight of matter which doesn’t seem to interact with anything – as a math cheat, since the weight of something is there…we just haven’t figured out what it is just yet. Along the way, Tyson also comments on topics like why the cosmos tends to produce spheres (planets, suns, clusters of galaxies…), the history of radio telescopes, and the supreme importance of the period table.

As someone whose most recent interaction with astrophysics has been The Big Bang Theory, since I haven't read anything in this area in four years, I found Tyson completely enjoyable.

The Sky is Not the Limit

The Sky is not the Limit: Adventures of an Urban Astrophysicist 
© 2004 Neil deGrasse Tyson
203 pages




          How does a young black kid from the Bronx become a world-famous astrophysicist, Director of the Hayden Planetarium and the second coming of Carl Sagan?  The Sky is Not the Limit is Neil deGrasse Tyson’s semi-autobiographical account of how he came to be seduced by the study of the  night sky,  one that doubles as a light work of popular science, promoting informed, critical thinking and asserting that yeah, science is cool.   Subtitled Adventures of an Urban Astrophysicist, Tyson’s memoir reveals that anyone can take joy from studying the stars, even if their view of the sky is washed out from city lights and their ambitions discounted by everyone they meet. The biography-turned-essay collection is Tyson’s most effective attempt so far to convert his gift for communicating science in public lectures into written form. Though his being seduced by heavenly bodies takes center stage, one essay ("Dark Matters")  sees Tyson make a rare comment on race. Although he received support from his parents and guidance from remarkable individuals like Carl Sagan and Isaac Asimov, Tyson had to overcome the obstacle for race: at every step along the way of his education people questioned his choice of occupations, from patronizing whites doubting his intelligence ("Why don't you just play basketball?") to patronizing blacks who thought astrophysics was too white and that an intelligent black man should be helping the race by  being a social activist instead. He persevered, however, and eventually became a celebrity scientist, the first black man (to his knowledge) to be interviewed on television and asked for his professional opinion on something outside of race or civil rights. The Sky is not the Limit covers astrophysics, math, skepticism, telescope stargazing as a first date (not successful), and September 11th, 2001.  Those looking for an entertaining science read should find this attractive.

  • Dr. Tyson hosts a weekly podcast called "StarTalk Radio", which is ridiculously awesome. He always hosts with a comedian, includes interviews, and fields questions from listeners about science and popular culture. The last show featured an interview...Buzz Aldrin, one of the first two men on the moon. Tyson has also spoke with Dr. Ruth (that "Dr. Ruth") and frequently features authors like Mary Roach and Neil Chaikin.

Space Chronicles


Space Chronicles: Facing the Ultimate Frontier
© 2012 Neil deGrasse Tyson; edited by Avis Lang
384 pages



On July 20th, 1969, America mesmerized the world by landing men on the Moon. For the first time in history, human feet stepped on the soil of another planet. But on July 21st. 2011, the Space Shuttle Atlantis touched down on the runway and the United States ceased to be a spacefaring nation, for the shuttle program had ended. Space Chronicles collects essays by astrophysicist and science advocate  Neil deGrasse Tyson which looks back on the history of the American space program and reflect on its legacy both to science and the human endeavor before arguing that the United States need to return to space with  bold ambitions.

Tyson first caught my attention a few years ago when a book described him as "the next Carl Sagan".  Here, he lives up to expectations as a passionate science communicator: he is earnest, witty, and urgently excited about the matter at hand. Although  ostensibly about the exploration of space, Chronicles is more fundamentally a book about the value of science -- and not just the knowledge itself, which enriches human experience and provides the spark for material progress, but of scientific thinking -- skepticism and wonder. The epilogue, which stresses the value of the "Cosmic Perspective", practically channels Sagan.

Science advocacy is the message, but Tyson uses the inspiring and exciting adventure of space exploration  as the messenger. Although enthusiastic about humanity's accomplishments thus far, Tyson avoids being labeled a starry-eyed optimist by consistently stressing the pragmatic aspects of space exploration, the technological boons. It's not the spin-off products like Velcro that Tyson has in mind, though: he points out that NASA's endeavors have  effected progress in other fields through "cross-pollination": one example he uses is that of the Hubble research team pioneering methods to put together meaningful conclusions from scant data while the telescope was impaired, methods that were adopted by cancer researchers to improve their analyses of mammograms.  More strikingly, though, he makes no attempt to interpret the space race of the 1960s as a bold, purposeful step forward in human exploration: instead, he sees it as being motivated by the desire for economic and military gains. Tyson emphasizes this not to convey cynicism about space exploration, but demonstrate how much was accomplished even though the motivations were less than inspiring, and to to point out that aerospace can continue to be a source of economic progress today.

In fact, aerospace is a source of progress for humans today, but not for Americans. Americans, Tyson laments, have gone backwards by standing still. Other nations are becoming the technological leaders of tomorrow, and Tyson -- an American, writing to motivate his fellow citizens to start believing in and working for the future again -- despairs of this. He sees hope in China's aggressive ambitions in space: if competition with Russia sent us to the moon back in  1960s, perhaps competition with China will take us further.For the time being, however, even our past accomplishments are beyond us now.

Space Chronicles sees Tyson communicate a great deal -- the history, motivation, and practical aspects of space flight, the value of science, critical thinking, and wonder, the United States' emphatic need to re-prioritize science, mathematics, and industry -- and do so with style. There is a slight weakness in the fact that Chronicles is an edited collection of essays and interviews, and not a monograph written as a cohesive whole. Repetition of certain facts, examples, and so on exists, but this is a weakness only and not a glaring flaw. As it stands, Chronicles  is impressive and engaging, of interest to both space enthusiastic and critics.

Death by Black Hole

Death by Black Hole and Other Cosmic Quandries

Although I've encountered Dr. Tyson before -- chiefly through interviews in podcasts like The Skeptic's Guide to the Universe and the Humanist Network News -- I've never read anything by him. His Death by Black Hole is a collection of columns and articles he has written for scientific magazines, edited for continuity. The 42 essays are divided into seven sections: "The Nature of Knowledge", "The Knowledge of Nature", "Ways and Means of Nature", "The Meaning of Life", "When the Universe Turns Bad", "Science and Culture" and lastly, "Science and God".

Tyson has been billed to me as the next Carl Sagan, and in some ways I think the description fits. He's definitely passionate about popularizing science, and criticizes scientists like Richard Dawkins who he thinks have lost touch with the common people. Tyson as an astrophysicists writes essays mostly dealing with those themes, but he addresses a few other fields and science in general before the book is finished. The majority of these were fascinating, even if I don't particularly understand the subfield being worked in, and humor abounds. It's worthy of a read.
