This page summarizes Chapter 3 (Future of the Medicine). "Kaku discusses robotic body parts, modular robots, unemployment caused by robots, surrogates and avatars (like their respective movies), and reverse engineering the brain. Kaku goes over the three laws of robotics and their contradictions. He endorses a "chip in robot brains to automatically shut them off if they have murderous thoughts", and believes that the most likely scenario is "friendly AI", in which robots are free to wreak havoc and destruction, but are designed to desire benevolence.[1]"

"Nanotechnology: Everything from Nothing?"

"Unlike conventional chemical rockets which use Newton's third law of motion, solar sails take advantage of radiation pressure from stars. Kaku believes that after sending a gigantic solar sail into orbit, one could install lasers on the moon, which would hit the sail and give it extra momentum. Another alternative is to send thousands of nanoships, of which only a few would reach their destination. "Once arriving on a nearby moon, they could create a factory to make unlimited copies of themselves," says Kaku. Nanoships would require very little fuel to accelerate. They could visit the stellar neighborhood by floating on the magnetic fields of other planets."

Merging with robots discussion

" The book is good enough to stimulate our imagination."

"The seeds of modern AI were planted by classical philosophers who attempted to describe the process of human thinking as the mechanical manipulation of symbols. This work culminated in the invention of the programmable digital computer in the 1940s, a machine based on the abstract essence of mathematical reasoning. This device and the ideas behind it inspired a handful of scientists to begin seriously discussing the possibility of building an electronic brain. "

For Discussion: Many young people and adults say that if we were to follow all the rules, we wouldn't eat anything, drink anything or rub anything on our bodies. Therefore they say hey don't care and will eat and do what they want. It's too hard to do anything about the situation as it id so we don't bother.

"The superior energy density of antimatter annihilation has often been pointed to as the ultimate source of energy for propulsion. Unfortunately, the limited capacity and very low efficiency of present-day antiproton production methods suggest that antimatter may be too costly to consider for near-term propulsion applications." Antimatter is not the same thing as dark matter or the lack of matter altogether. A single teaspoon of antimatter can destroy the metropolitan area of New York City. Antimatter is extremely difficult to harness, and prohibitively expensive as of now. However, in the future, antimatter may be able to be used to power rockets into the depths of outer space. This concept was discussed in Physics of the Future.

"When discussing the possibility of interstellar travel, there is something called "the giggle factor." Some scientists tend to scoff at the idea of interstellar travel because of the enormous distances that separate the stars." This site goes into great detail about the amount of energy and the level of technology required for interstellar space travel. Michio Kaku describes that many scientists believe that interstellar space travel would be impractical and impossible, considering the massive distance between stars. For instance, traveling at light speed would take you roughly 100,000 years to reach the edge of the Milky Way galaxy. This is a reliable source, considering it was written by Michio Kaku himself.

"The Terrestrial Planet Finder (TPF) uses a small collection of high sensitivity telescopes (probably 4 large 3.5-meter telescopes) with revolutionary imaging technologies. It will measure the temperature, size, and the orbital parameters of planets as small as our Earth in the habitable zones of distant solar systems. Also, TPF's spectroscopy will allow atmospheric chemists and biologists to use the relative amounts of gases like carbon dioxide, water vapor, methane and ozone to find whether a planet might support life. The launch was to be anticipated between 2012-2015 until NASA's budget cuts." The Terrestrial Planet Finder was discussed in the book Physics of the Future. This object will have better optics and will be approximately 100 times more sensitive than the Hubble Space Telescope. Its infrared sensors will be able to nullify the intense radiation from a star by a million times, revealing planets that have been undiscoverable otherwise. This radiation will even have the power to completely remove a star from the universe, if one ever so desires. The Terrestrial Planet Finder is predicted to be an extremely valuable tool to astronauts and scientists within the next century.

"How can we apply our growing understanding of the biology of cancer to combat the disease? Prevention is always better than cure, and as we have already discussed in the first part of this chapter, many cancers can indeed be prevented-" This website is about the possible ways we might be able to cure cancer in the future. First it describes how cancer works and why it is so hard to cure. Then there is a list of multiple different predictions about how all the forms of cancer may be cured in the future. We can use this website for the "Coexisting with Cancer" theme, it can help us brainstorm our own ideas on how cancer may be cured. I know this source is reliable because all of the information is cited very clearly for the reader.
