Summary of: The Sun, the Genome and the Internet: Tools of Scientific Revolutions
By: Freeman Dyson


In ‘The Sun, the Genome, and the Internet: Tools of Scientific Revolutions’, Freeman Dyson explores the power of technology in shaping the future and fostering social justice. The book delves into how science originated from the fusion between philosophical thinking and skilled crafts and the significance of tool-driven scientific revolutions. Dyson dreams of a world where solar energy, genetic engineering, and the Internet work together to create a socially just world, transcending geographic and socioeconomic boundaries. As you step into this summary, you will discover insights into how the development of key technologies can drive scientific revolutions and contribute to a fair society for all.

The Power of Useful Science

In the book “A Mathematician’s Apology,” mathematician and professor Godfrey Hardy asserts that science is only useful if it promotes destruction or wealth inequality. However, science can be useful without causing harm. John Randall, a physicist, demonstrated this by inventing the cavity magnetron that gave the Allies an advantage in WWII and later pioneering X-ray crystallography, which led to the discovery of DNA. Randall’s work with tools drove scientific revolutions and showed the potential for science to be both useful and beneficial.

Science and Craft in the 20th Century

Science and craft industries developed separately but became inseparable in the 20th century, with recent scientific revolutions being tool-driven. Skilled crafts were initially threatened by mass production, but the age of computers revived craft industries in software writing. Synthetic viruses may drive a future scientific revolution through their ability to enter cells, discriminate between healthy and malignant cells and turn specific processes on and off.

Science has its roots in the fusion of two old traditions- philosophical thinking traced back to ancient Greece and skilled crafts from medieval Europe. Scientific concepts developed from philosophy, while crafts provided the necessary tools. However, until the end of the 19th century, science and craft industries developed along separate paths. The 20th century brought about a change: science and the craft industries became inseparably linked.

The computer manufacturing industry, which started as a work of craft, is now considered a functional commodity of the past. However, software writing has seen a resurgence in craft industries. Skilled artisans must work hand in hand with programmers to create powerfully functional and visually appealing software.

Most scientific revolutions have been driven by tools rather than concepts, and recent discoveries in science came about from new tools and methods. Molecular biologist Fred Sanger, known for developing the technical tools that helped decipher the sequence of bases in long strings of DNA, is one of the great tool-builders of our time. His discovery that, in long strings of genes, the sequence of bases resembled a Mozart duet played by two musicians reading from the same sheet of music, with one playing from top to bottom and the other from the bottom up, was due to his choice of a well-known virus and a new tool.

Viruses, which combine standardization with variety, reproducibility with malleability, ruggedness with specificity and precision with cheapness, provide an excellent tool for scientists. If nature had not invented viruses, humans would have had to. Synthetic viruses may even lead to a scientific revolution in the future as they can enter cells and turn specific processes on and off, allowing researchers to examine the result. It may even be possible to design synthetic viruses that distinguish between healthy and malignant cells and destroy the latter.

In conclusion, science and craft industries may have followed separate paths until the 20th century, but they have now become inseparable. Recent scientific revolutions were driven by new tools rather than concepts, while skilled crafts have revived in software writing. The future may see a new scientific revolution brought about by synthetic viruses’ ability to enter cells and specifically turn on and off cell processes.

The sustainability of scientific projects

Sustainable scientific projects are cheap enough to continue indefinitely, while unsustainable ones require a significant amount of resources and often mark the end of an era. The example of the Apollo program highlights the unsustainability of expensive projects. However, the cost-effective PLANET project, linking under-utilized telescopes for gravitational tomography, is described as opportunistic, spontaneous, and undirected. The internet and its ability to make a few dollars go a long way is key to its success. The author emphasizes the need for medical scientists to follow the lead of astronomers by inventing their own tools, such as a desktop gene sequencer and protein microscope. These inventions can lead to revolutionizing the study of cells and viruses, but their cost needs to be in line with sustainability.

Technology and Social Justice

The advancements in solar power, genetic engineering, and the Internet hold the potential to create a socially just world where every community can thrive equally. The application of ethics in technology is crucial to achieve this vision. Space travel, on the other hand, is deemed irrelevant. While technology can significantly contribute to social justice, it may come with certain drawbacks, such as dispossessing certain classes of people. Nevertheless, history provides examples of how technology can eliminate unjust class systems. Household appliances and synthetic fabrics are among the technologies that have contributed to creating equality between different social classes. The author emphasizes the importance of technology in promoting social justice and highlights the need for ethical considerations while developing new technologies.

Solar Energy for Poverty Reduction

This book suggests that the key to sustainable development is the provision of cheap solar energy to rural tropical villages. The author argues that the population explosion and rural poverty must be addressed, and this can be achieved through affordable solar energy systems that can provide enough electricity to power essential appliances such as radios and TVs. However, current costs are prohibitive for most households. The author suggests that genetic engineering could help make solar energy systems cheaper and thus more widely accessible. This book is a must-read for people interested in sustainable development and renewable energy technologies.
