Great thinking on time

Here is a growing list of books, podcasts, videos, and groups related to the class.

The HS-NY Library
The wonderful library at HS-NY

Bibliography

The first two books: Rovelli’s “The Order of Time” and Griffiths’ “A Sideways Look At Time” are required for the course.

The Order of Time

2018, Riverhead Books. A small gem of a book, Rovelli does a perfect job distilling what the most recent interpretations of physics tell us about the reality of time. Available online through NYU.

A Sideways Look at Time

2014, TarcherPerigee. A challenging book that forgoes the typical account of time through human history, in favor of a poetic approach. Not perfect, but few books combine as many thought provoking topics under one roof. Recommended by Ariel Hein. An excerpt is available online. An excerpt is preserved in the course packet.

Here are several other books on Time I’ve come across. I have copies of most of these, and am happy to lend them out; several are available online through NYU’s library.

The Clock of the Long Now

I’ve followed the Clock of the Long Now project for a long time. Here, Brand and other authors offer reflections on time, including the useful distinction between chronos and kairos. Available online. Brand’s Ted Talk. Available online via NYU.

The Nature of Time

1975, Holt, Rinehart and Winston. Whitrow gave a series of BBC lectures about time, and published a number of books expanding those lectures (“What is Time?”, “Time in History”, etc.). I really like the broad perspective of these books – this one in particular balances historical, cultural, technical and scientific ideas about time nicely. Physical copy at the library.

From Eternity To Here

2010, Dutton Press. Carroll (along with Brian Greene, see below) is at the forefront of physicists tackling big ideas and bringing them to the public. See also Carroll’s podcast and video series. He also authored a Great Courses class in Time. Carroll’s more recent book “The Biggest Ideas in the Universe: Space, Time, and Motion” is available through NYU online.

Until the End of Time

2020, Knopf. Like Carroll, Greene vividly ties together cosmology and entropy to get at the nature of time.

The Ministry for the Future

2020, Orbit. If I were to generally include science fiction titles this list could be nearly infinite. However, Robinson’s Ministry for the Future stands out for its intense focus on charting the immediate near-term future and humanity’s response to climate change, itself a challenge on multiple timescales, most hard for humans to grapple with. Available online through NYU library.

Relativity

2015 edition, Princeton University Press. Turns out Einstein’s own popular science account of relativity is one of the best. He begins with Euclid, and a reader with solid geometry can follow the arguments at least through Special Relativity. Up until this point great minds had speculated as to the true nature of time; Einstein, using his imagination, reached tangible conclusions. This edition is available online through Bobst and includes extensive supplemental material.

I also recommend checking out the paper that started it all: On the Electrodynamics of Moving Bodies (1905). Einstein published three other papers that year, all significant, earning the year a name: Annus Mirabilis, or the Miracle Year. And the famous Einstein’s Dreams by Alan Lightman.

It’s About Time

A very useful and lucid companion to Relativity. Available online.

A Brief History of Time

Begins with the Big Bang. Interesting notes about Entropy. See also Hawking’s discussion of time here.

Longitude

A master writer telling the story of the invention of the Harrison H4 chronometer that won the X-prize of its day by keeping accurate time at sea. Find the illustrated edition! The “regular” addition is available online through NYU.

The Clock We Live On

Love this book because a) it’s Asimov the science teacher before he became Asimov the science fiction author, and b) it’s written for intelligent children so I can more or less follow it. If you adjust to the sort of 50’s pipe smoking vibe there’s a lot of useful information on how the peculiarities of our situation (a planet tilted just so rotating and revolving at certain rates etc) leads to various calendars and timekeeping methods through history.

The Doomsday Equation

Astronomy is a long progression disabusing us of the idea that we are at all special. The sun doesn’t revolve around us, and even our solar system and galaxy are unremarkable. This is known as the Copernican Principle – there’s nothing particularly unique about where we are in the universe. So what if we apply this idea to time? Where, in the timeline of all humans who will ever exist, are you?

The History andPractice of Ancient Astronomy

A good read after Asimov for going into more depth as to how ancient civilizations reckoned the motion of the stars and planets. Available online through the NYU library.

Geared to the Stars

An account of astronomical machines, especially orrerys, through the ages. Mainly focused on Europe starting in the Renaissance, omitting most Chinese and Arabic developments, but otherwise exhaustive within its focus. Out of print πŸ™ but semi-available through archive.org (and I have a copy if you want to see!)

A Portable Cosmos

Vivid historical setting as well as technical details of the Antikythera Mechanism. Dr. Jones is a member of NYU’s Institute for the Study of the Ancient World, and has created a number of resources concerning time in antiquity, including a recent exhibit Time and Cosmos. Available online through NYU library.

From Sundials to Atomic Clocks

Published by the NIST, this pamphlet/book is, if a bit dated, a good account of the physics underlying timekeeping. Don’t be thrown off by the goofy illustrations – good content. Available as a PDF along with many other time-related online resources from NIST.

Handbook of Archaeoastronomy and Ethnoastronomy

Just found this resource while researching the oldest gnomon, a painted stick at the Taosi archaeological site. A wealth of information, beginning with the essay “Concepts of Space, Time, and the Cosmos” by StanisΕ‚aw Iwaniszewski. Available online through NYU. Or $700 on Amazon…

Sundial book cover
Sundials – Design, Construction, and Use

Denis Savoie, Praxis 2009. A detailed technical explanation for making all manner of sundials, available online through the NYU library.

More recent reads to be added here: Burkeman’s “4000 Weeks”, Loomans’ “I’ve Got Time”, “Dilla Time” by NYU’s Dan Charnas, several books on sundials. R. N. and M. W. Mayall’s excellent work on Sundials was serialized in Scientific American in the 1930s, and available through NYU Library. Time: A Very Short Introduction by Jenann Ismael is also available online.

So many other possibilities! For more inspiration see Maria Popova’s list of 7 Books on Time and her Atlantic piece on Visualizing Timelines.

Julian Barbour argues in a book and this essay that time does not exist.

Ted Chiang’s short stories often feature imagery from horology and space exploration, and his story Exhalation is specifically about the relationship between entropy and time. The Story of Your Life (the basis for arrival) is also about time.

Several non-books or online texts: This guide to the History and use of Astrolabes, by Darren Hayden. Or if you prefer, Chaucer’s. The beautiful design of Asa Smith’s Illustrated Guide to Astronomy (also via Archive.org). A visual guide to general relativity.

Video and other media

Check out these time-specific TED videos. There are physics explainers, like this short one:

A short animated explainer

As well as valuable insight into cultural aspects of time such as:

“Brittney Cooper examines racism through the lens of time, showing us how historically it has been stolen from people of color” – TED

PBS’ excellent digital series, Space Time, deals with things like understanding the speed of light and causality. Start here:
