Time Is Not Money. Sleep Is.



You’re on deadline, and the project just isn’t coming together. You fuss, polish, tinker, and do just about everything you can to make it gel, but despite your best efforts, you just can’t seem to make any meaningful headway. So you stop. You quit for a day and get a good night’s sleep. Next morning, the thing comes together beautifully, seemingly without a hitch. Why is that?

Some months ago*, I interviewed a sleep scientist for an article in a science magazine. The doctor’s words came back to me as I read a section in Chapter 9 of The Wealthy Freelancer, entitled “Take Time To Incubate.” It’s the part of the book where authors Steve Slaunwhite, Pete Savage, and Ed Gandia point out that time away from a project—i.e., “sleeping on it”—often works wonders.

It does, and here’s why.

Our brains are compulsive digital recorders. They collect information about every single experience we have. You meet a client over coffee to hash out details for an upcoming report. While your conscious mind deals with the business at hand, your unconscious mind slavishly records everything around you: Your client’s body language. The light levels in the coffee shop where you meet. The music on the loudspeaker. The weather. Every freaking thing.

This is a wondrous ability, but you don’t need to remember everything. You just need to remember the important stuff.

“Remembering the important stuff” is called learning.

The sleep doc used this analogy. “If I teach you how to shoot baskets,” he said, “and I test you after you practice a few hours, chances are you’ll retain a certain level of skill. But if you go home and sleep, the next morning you’ll be better at it than when you finished your practice. It’s not just that time has gone by.Improvement happens when you sleep. If you don’t sleep, you don’t improve.”

Scientists think sleep has a pruning effect. As you sleep, your brain prunes unimportant memories— experiences, colors, sights, sounds, false starts, dead-end concepts—like the dead branches of a tree. Your brain decides what to discard and what to keep.

The goal of sleep is to organize your thoughts and consolidate learning.

You may bristle at the suggestion that you are still learning. But competent freelancers know that projects that push them into new territory help them grow.

The temptation as a freelancer is to ruthlessly push yourself to finish a task, even if it’s not going well, because your income is tied to how quickly you can finish up and invoice.

But you might work smarter if you consciously enlist your unconscious to do its job.

Want to consistently land high-paying projects and clients? Want to raise your income? Want to improve, work efficiently and prosper?

Go to bed.

My Unpublished Interview with Astronomer Vera Rubin


In 1999, I wrote an article for Discover magazine about Ralph Alpher, one of a trio of scientists responsible for conceiving the Big Bang Theory. During the course of reporting that article,* I had occasion to interview Vera Rubin, the celebrated dark matter astronomer who died at the age of 88 on December 25, 2016. Articles (like these here and here and here) covering her passing noted that she ought to have received the Nobel Prize but never did, no doubt because she was a woman working in a field at a time when men dominated.

As it happens, my interview with Dr. Rubin touched on the painful topic of those who deserve but do not win Nobels. We were talking not about her work per se, but about Alpher and other male colleagues of hers. Her comments were insightful but I didn’t have room in the final story to share everything she told me. I’m releasing the brief transcript now because I think they shed light on Rubin's thinking on the matter, and because she and the three cosmologists at the center of the Big Bang story are no longer with us. (Gamow died in 1968, Herman in 1997, and Alpher in 2007.)

Back in the 1940s, along with his thesis advisor, George Gamow, Ralph Alpher wrote the first paper on the origin of elements in the universe. Later, he wrote a second paper with his colleague Robert Herman that theorized that the radiation of that first bang should still be bathing the universe. The men actually predicted how that 14 billion-year-old relic—called cosmic background radiation—could be found. At the time, radio astronomy was in its infancy and Alpher and Herman could not find scientists willing to gamble on their idea. But in the 1960s, they were proved right when a team at Princeton found proof of the Big Bang in exactly the way Apher and Herman had predicted.

The Princeton team received the Nobel Prize in 1978 for their work, yet the work of the earlier scientists was seemingly ignored. To make matters worse, later books and academic journal articles perpetuated the error by either incorrectly attributing Gamow, Alpher and Herman’s work, or ignoring it entirely. By then Gamow had died, but Alpher and Herman, who had left academic for industry during much of the ensuing years, devoted nearly 30 years of their lives trying to set the record straight.

Here’s what Dr. Rubin told me about how that miscarriage of scientific justice impacted the lives of the two men she called friends.

How were they affected by the whole thing?

I don’t think either of them put it behind them. It was a major factor in their lives. I think they both felt that they had been unfairly treated by the entire field. [My husband mathematician-physicist] Bob [Rubin] and I used to tell Bob Herman that we really thought they should just forget about it.

The fact that neither one of them were doing a lot of cosmology or astronomy really meant that their work just wasn’t in the forefront of astronomy. One way people learn about what you’re doing is by your continuing to do it. Your current work is always kind of a reference to your past work. But in their case, they both went off and did something very different, so there was no one to bring their early work to the attention of the community except them themselves. It was just an unfortunate circumstance, I guess.

But I think it bothered [and] continues to bother Ralph. I think it bothered Bob [Herman] too. There were constantly books written about the history that they didn’t think was correct, and they continued to write authors to make corrections. That’s probably what they should have done, but it meant it wouldn’t be something they could really put behind them. So I think these things were always continually being in the forefront. It’s been 33, 34 years.


Dr. Alpher says he’s writing a book to set the record straight once and for all.

I suspect that it will be a very bitter book. He and Bob Herman are very, very dear to us and it was a horrible injustice, but I don’t know what you do in such a circumstance. It would have been nice if he had had a happier life. They could have known that they did something very, very valuable and they could have been happy with this. I think perhaps injustices are in the eye of the beholder, unfortunately. But they were still the first people to do it and they did get a wide variety of enormously prestigious awards. Perhaps they could have asked themselves the alternative. It could have not been discovered during their lifetime. Wouldn’t that have maybe been worse? There’s no doubt that they could have been and should have been treated nicer by the community. They really do have a legitimate complaint. But they could have responded a little differently.

I think the truth is that in science, when I was very young a very wise man said to me, “In science most of your satisfactions have to be internal ones.” I think that that in a sense is correct; you have to be happy. They should have been exuberant with the work that they did. It was rediscovered. It was great. They had not gotten the recognition they deserved, but if their personalities had been different they could have been happy with the knowledge of this great thing they had figured out. And they perhaps could have even been treated better by the community if they had not just been so obviously angry.

I think they are remarkable, wonderful people, and they did something that was wonderful. It would have been very nice if that could have been such a joy that they could have embraced the community and which in turn might have embraced them. But none of that happened. 

They never forgot it, in ways that I can’t even repeat. But they could tell you who said something a little bit better and who said something a little bit worse. Sentences were examined in a way that I think the poor authors never intended them to be.

Bob [Herman] and Ralph have been very dear friends for a long time. With Bob [Herman] I or my husband have actually said, “Why don’t you, you know, talk him out of going on with this?” It never worked. It really affected them.

I don’t know if the Nobel Prize complicated things. If Penzias and Wilson had not gotten the Nobel Prize… But there too, and now I will say some things that are truly awful but this is how the establishment behaves. Someone has to nominate you for the Nobel Prize.


I didn’t know that.

Yes, yes, yes. [Nobel Prize-winning chemist] Harold Urey used to brag—I knew him and he used to brag that that 11 of the people he’d nominated had gotten Nobel Prizes. If you’re outside the establishment, you stand a much poorer chance of having these good things happen to you. If they really had not left the academic world, things may have been different. I really think there lies the explanation. Their lives might have been very different if they had remained in the academic world.

Oliver Sacks: Farewell and Thank You

I was saddened to hear of the passing of Oliver Sacks, whose work made a big impression on me during the handful of years I was writing for science publications. He and I had never met, but he did one thing for me that I’ll always be grateful for. He chose one of my nonfiction articles for the Ecco/HarperCollins annual anthology, Best American Science Writing 2003. It was my second appearance in that collection, and I was just as surprised the second time around as I was for the first. So thank you, Dr. Sacks. Hail and farewell.

The story he picked was the one I did on sanctuaries for retired lab chimps. You can read it here.

New book: The Scientist & the Sociopath is out!

The Scientist and the Sociopath by Joseph D'Agnese

I’m pleased to announce the publication of my new book, The Scientist and the Sociopath, a collection of some of my best science writing.

At least two of the articles in this collection have already appeared in the prestigious Best American Science Writing anthologies, but it’s nice to have one volume collecting my pieces from Discover, Wired and Seed.

The book, which features a cover by awesome artist Jeroen ten Berge, is something of a milestone: it marks my foray into digital publishing. The title is available immediately as an eBook on Amazon and Smashwords. In the weeks to come, B&N, Apple iPad, Sony, and all the rest will be next. You can download a free sample from all of these sites onto your digital device. You can always find more details on the book page of this website. But for now, here’s the pitch:


A modern-day computer scientist struggles to unlock the secrets of a mysterious book apparently written in a secret code, matching wits with a sociopathic con man who died 400 years ago.


A humble cosmologist conceives one of the biggest theories of the universe—and watches helplessly as the Nobel Prize goes to someone else.


A maverick doctor investigates bizarre ailments using a method that seems shockingly radical in modern medicine: befriending patients and asking them how they feel.

THE SCIENTIST AND THE SOCIOPATH presents remarkable nonfiction stories, some of real-life scientists tackling theories and discoveries that will change our world, others of laymen grappling with some aspect of science in their lives.

Along the way, there are smashed ancient skulls, dead chimps in the back of pickup trucks, flying snakes, lordly windmills, haunted warriors, and beautiful, geeky kids building us a new world, one Lego at a time. 

These all-too-human players overcome their own foibles to make sense of the unknown, touching on everything from the Big Bang theory to tissue engineering, human evolution to cryptography, strange animals, robots, and the secret of human ingenuity. 

Culled from the author’s extensive reporting for magazines such as Discover, Wired and Seed, these tales are bundled together for the very first time. This collection includes two bonus stories on green energy and two never-before-seen stories.
