Summary of The Double Helix 

4.5 . 1188 reviews

Short summary

James Watson and Francis Crick were the first geneticists and molecular biologists who cracked the DNA structure. Many scientists didn’t have faith in their research, and the public didn’t place much value in the role of DNA in our lives. But Watson and Crick knew that revealing this secret will change the understanding of biological processes. Maurice Wilkins, a biophysicist, was the one who believed in them and contributed to making this brilliant discovery. His X-ray images of DNA assured Watson and Crick that they had still more to learn about its structure. They made many mistakes and fought with their colleagues, but they withstood all the challenges, found what DNA looked like, and won a Nobel Prize in 1962. "...I do not believe that the way DNA came out constitutes an odd exception to a scientific world complicated by the contradictory pulls of ambition and the sense of fair play." ~ James Watson, KBE

James Watson, inspired by Maurice Wilkins, a biophysicist, decided to take DNA X-ray work. He was already interested in finding out DNA structure; he was absorbed by gene studies in college. Watson wasn't keen on chemistry lessons and hoped that his interest in genes wouldn't require learning it. Admitting his laziness, he shared that he tried to avoid complex subjects by focusing on researching birds. Attending classes at Indiana University, he attempted to devote his efforts to biochemistry, ending with unfavorable bunsen burner use. As you might have guessed, he caused a minor explosion, resulting in him giving up chemistry and possibly saving Indiana from other explosions.
Even brilliant scientists can sometimes be lazy, so stop torturing yourself for not wanting to do some tasks.
Later on, life gave him people who managed to teach him chemistry—Herman Kalckar, a biochemist and Watson’s mentor, and Salvador Luria, a microbiologist. During his journey to Denmark, Watson learned numerous chemical facts which could beneficially influence his DNA study. Luria, interested in researching DNA structure, focused on confirming or refuting a specific suggestion among geneticists. They supposed that viruses were the key to DNA structure because they resembled naked DNA. Luria and other scientists examined bacterial viruses in the 1940s. However, Luria wasn't sure that finding out a virus's chemical structure would be enough. He thought that researchers should know more about DNA to investigate it more effectively.

All the efforts to make Watson learn chemistry seriously failed. He didn't believe that, by any chance, it could be related to his study of DNA. Besides, Watson didn't understand Kalckar's explanations. He met Ole Maaloe, Kalckar's friend, who was enthusiastic about working with viruses. Watson visited Maaloe's lab so often that it broke the terms of fellowship, which required him to work with Kalckar. However, during one of the rare moments spent in Kalckar's lab, Watson found out that his mentor wanted to get a divorce, so that he couldn't teach the future DNA structure discoverer. Now, he could visit Maaloe as often as he wished without breaking any rules.
I could cycle each day over to Ole's lab, knowing it was clearly better to deceive the fellowship electors about where I was working than to force Herman to talk about biochemistry. ~ James Watson, KBE
This summary will reveal to you how a scientific world struggled to know something that seems so simple to us now. Which processes did they follow to discover the DNA structure? What challenges did they have to overcome? It wasn't laziness and the absence of desire to study chemistry; scientists also struggled with the lack of acknowledgement but never gave up. This summary will inspire you to proceed with doing something you love.
second key point

The things a person is ready to give up for science

Kalckar invited Watson to visit Naples, where the latter decided to pay more attention to genetics. Maurice Wilkins arrived in Italy as well. But scientists weren't talking about science. They spent time on excursions or sitting in the lab, which irritated Watson, who had to listen about biochemistry instead of focusing on genetics. He dreamt about discovering the great secret of DNA but felt frustrated that he didn't accomplish anything.

Headway is the answer! No longer accumulating books I never read. With Headway, I initially chose the areas important to me such as productivity, time management, etc., and each day I'm provided several book summaries from which I devote 20 minutes or more each day reading. All of this on my phone! My life has improved with Headway. Truly my most useful app.

I've gotten multiple books out of the library with the intent to read them, but always have a hard time finding the time. This app has helped me finally be able to get to them. Summarized, yes, and thank goodness too! Just short enough I can finish one on my way picking kids up from school/practice, or while I'm cooking dinner. I can't wait to listen to them over the summer when we visit the beach!

It amazed me! There is the possibility to highlight the most important points of each book and instantly translate unfamiliar vocabulary. With the ability to review the searched words. It's a great way to learn more about English as well. The price is great.

I’m enjoying what I’m learning on headway.each summary comes with quotes at the end which you can save to help you remember key points. You can listen or read, I’ve found that reading puts me to sleep before I can finish but the listening feature keeps me engaged and I can finish in a brief amount of time if not one session.

Exactly what I need! I always have booklist to read, but can't committed enough to finish/start bc of too much pages. Headway is really helpful and concise with their summary. What I love the most is that the essence of the book is well crafted, so I don't only read the key points, but also there's the story and how personality of the author still well shown through the summary. Well done!
