Uranium

Gardner, Jane P. Uranium. 2018.64p. ISBN 9781422238479. Available at 546.43 GAR on the library shelves.

Uranium book cover

Uranium, a dense, silvery-white metal, was first discovered by Martin Klaproth, a German chemist, in 1789. He isolated uranium oxide from pitchblende, a mineral found in the Joachimsthal silver mines in Bohemia. The discovery of uranium marked a significant milestone in the field of chemistry and physics, as it paved the way for further exploration of radioactivity and nuclear energy.   

The true potential of uranium as a powerful energy source was not realized until the 20th century. Scientists discovered that certain isotopes of uranium, particularly uranium-235, undergo nuclear fission, releasing immense amounts of energy. This process, known as nuclear fission, is the basis for nuclear power generation. Nuclear power plants harness the energy released during fission to generate electricity, providing a low-carbon alternative to fossil fuels.  The same process could also be used to fuel bombs, however, and humanity entered the nuclear age when atomic bombs were dropped on Japan in 1945. 

The use of uranium also raises concerns about nuclear proliferation, vulnerability of plants to environmental hazards like Fukushima or to human error like Chernobyl, and the safe disposal of nuclear waste. Scientists and engineers are continuously working to develop advanced nuclear technologies, such as nuclear fusion, which promises to be a cleaner and more sustainable energy source. By addressing these challenges and advancing nuclear technology, we can harness the power of uranium to meet our energy needs while minimizing environmental impact.

Nuclear War: A Scenario

Jacobsen, Annie. Nuclear War: A Scenario. 2024. 400p. ISBN 9780593476093.

Nuclear War: A Scenario book cover

The dropping of atomic bombs on Japan to end the Second World War in 1945 ushered in the threat of nuclear war and the destruction of the human race as we know it. Nuclear War: A Scenario makes it perfectly clear that the U.S. policies of nuclear deterrence, escalating deployment of nuclear weapons, and mutually assured destructions are nothing but wishful thinking. In this scenario, on a a beautiful spring afternoon, North Korea launches a ballistic nuclear missile at Washington D.C. Following protocol, the president is evacuated, and the entire military apparatus of the United States engages in its highest response level. Interceptors are launched, but they fail, and the missile continues on its trajectory. 

With less than 30 minutes from launch to detonation, U.S. authorities go through pre-planned hoops, and over a dozen missiles are launched back at North Korea. Russian satellites notice the launch. With these missiles flying towards Russia, it is impossible for the Russians to determine if they will go over or land on their territory. The Russians thus respond with a massive barrage of missiles heading for Europe and the United States. Even if the Russians chose to ignore the threat, the missiles heading to North Korea would land near China and kill millions of Chinese citizens, forcing the Chinese to respond and launch their own missiles. When U.S. satellites see the Russian launch, Strategic Command launches all remaining American nuclear missiles. Thus, within the span of two hours, over 2,000 nuclear bombs explode across the globe. 

Folks who were not instantly vaporized by the fireballs in the millions of degrees are killed by the blast, or quickly die of burns, or, more slowly, of radiation poisoning. With so many toxic particles in the skies, the temperature drops by more than 20 degrees, and agriculture is no longer possible due to contaminated water. Mammals and fish quickly die out, followed by amphibians and reptiles. Only insects, with a higher tolerance to radiation, survive. Even if you somehow avoided being killed in a nuclear exchange, the lack of everything following destruction on such a massive scale would inevitably lead to death in the short or medium term. Pockets of humanity may survive, but the world as we know it would essentially stop to exist.

In a horrifyingly and accurately portrayed fashion, Nuclear War describes how the firing of even one nuclear weapon will trigger a rapid and massive response that will inevitably be misinterpreted by another one of the nuclear powers as an attack on themselves, and in the mind frame of use them or lose them, all nuclear missiles end up deployed within two hours of the first launch. Interviews with experts in the field, politicians and generals who have served in these roles, and through reviews of publicly available documents detail with precision what would happen, and why we must do everything we can to avoid nuclear war.

Aluminum

Csiszar, John. Aluminum. Part of The Chemistry of Everyday Elements. 2018. 64p. ISBN 978-1-4222-3837-0. Available at 546.67 CSI on the library shelves.

Aluminum book cover

Aluminum is one of the most prevalent materials in our environment, but we often ignore how much of it there is, and how it is used. First isolated through chemical reactions, aluminum's properties of low density and high resistance to corrosion make it an excellent metal for industrial applications. Aluminum is never found in the environment, as it chemically reacts with things around it. Once purified, aluminum is present in lightweight structures, electronics, cars, and wind turbines. It is present in trace amounts in our food.

Aluminum's excellent corrosion resistance is due to the formation of a thin, protective oxide layer on its surface, which acts as a barrier against further corrosion. This property makes aluminum suitable for outdoor applications and environments with high humidity. Additionally, aluminum is malleable and ductile, meaning it can be easily shaped and formed into various products. Its high thermal conductivity makes it an efficient conductor of heat, making it a popular choice for cookware, radiators, and heat exchangers. Finally, aluminum is recyclable and can be recycled indefinitely without losing its properties, making it an environmentally friendly material.

Nature Meets Nurture: Science-Based Strategies for Raising Resilient Kids

Borelli, Jessica, and Stacy Doan. Nature Meets Nurture: Science-Based Strategies for Raising Resilient Kids. 2022. 350p. ISBN 9781433833106.


Whether a person is shaped by their environment, their family, or their hard wiring remains a source of debate, with research pointing to both sides of the arguments to describe why some individuals are successful despite poor genetic conditions or an inadequate environment, while others have both and seem to not amount to much. In Nature Meets Nurture, the latest investigations on brain science, epigenetics, and social research are analyzed, translated into plain English, and applied to specific situations to demonstrate skills and actions parents can take to help their child exceed the debate of nature versus nurture and instead support whole person emotional well-being.

Genetics are very important, and influence a child even before birth. But they are not the end of the conversation. The environment that surrounds the child, even before birth, also has a direct impact on the child's development in the womb, and, following birth, their emotional bonding. Strategies to deploy the best of genetics and environmental circumstances are presented, with the goal of creating a more resilient child, equipped with skills designed to reduce stress, promote social awareness, and improve learning. 

With so much stress in our lives, whether nature or nurture has a larger influence on a person is moot. We need to deal with both, and we need to incorporate the best that each bring to ensure that children can grow into well-loved and successful individuals.

The Order of Time

Rovelli, Carlo. The Order of Time. 2018. 240p. ISBN 9780735216105.


What is time? Why is time so important in our lives? What role does it play? Does it really exist? These are all questions that arise as one ponders the nature of time itself. Scientists, artists, and philosophers have all attempted to explore the true nature of time, without much success and with some contradictions. Time passes faster in lower gravity, so that someone standing on top of a tall mountain will live less time than someone at sea level. It wasn't until the telegraph, which ushered the means of communicating around the globe almost instantaneously, that the world suddenly needed to synchronize clocks. Prior to that, noon in one spot was the time where the sun was highest, and because of slow transportation methods, it didn't really matter that the time in a neighboring town wasn't quite the same.

An industrial and communications revolution later, however, it became necessary to track time in precise intervals, to ensure the smooth operation of the marketplace and of the government. But for humans who had spent thousands of years experiencing time based on the sun's movements in the skies, this transition to accurate time keeping shook the very foundations of how we perceive time. In The Order of Time, Rovelli seeks to reconcile us with a concept that may be more in our head than an actual immutable law of physics.

Fans of philosophical musings and those who enjoy reading scientific information will appreciate the questions that this book sparks, and will wonder at the true nature of time.

Infectious Disease Prevention: Protecting Public Health

Mooney, Carla. Infectious Disease Prevention: Protecting Public Health. Part of the Understanding Infectious Diseases series. 2022. 64p. ISBN 978-1-6782-0158-6.



The Covid-19 pandemic brought infectious diseases back to the fore of public health policy. Infectious diseases easily spread to a population, are hard to control and prevent, and do significant damage to the organisms they infect. In order to ensure public health is protected from infectious diseases, scientists and governments take many steps, some of which are controversial, while others are not. 

Though probably currently the best known infectious disease, Covid-19 competes with diseases that continue to make people sick in the United States, but which can be deadly in less developed countries. Diseases such as polio, e. coli, and sexually transmitted infections afflict many, and can cause death. Other more exotic diseases, such as Zika or Ebola, continue to present challenges in infection avoidance. Infectious diseases can be waterborne, transmitted through food, through the air, by person-to-person contact, or through animal vectors.

In an era where international travel means any disease is potentially less than a day away from any point on the globe, it is essential to understand how infectious diseases are spread, and what we can do to stop them.

 How We Got to the Moon: The People, Technology, and Daring Feats of Science Behind Humanity's Greatest Adventure

When President Kennedy declared in 1961 that the United States would travel to the Moon before the end of the decade, it set forth a massive industrial and scientific effort to achieve what had previously been impossible: Escape Earth's gravity and reach for the stars. Four years prior, the Soviet Union had launched its first satellite, shortly followed by the first animal in space then the first human in space. Embroiled in a Cold War with the Soviets and fearing falling behind technologically and scientifically, the United States poured vast amounts of resources on creating the largest rocket ever built. 

Over the next eight years, countless technological challenges were overcome to assemble the Saturn V rocket and its components, including the landing module and the command module. A building to house the rocket was built, a way to move the giant rocket to the launch pad was designed, space suits to protect astronauts were created and sewed by expert hands, and multiple other complex issues were resolved with determination and grit. On July 20, 1969, the first astronaut walked on the surface of the Moon. It was an accomplishment for humanity, but specifically for the hundred of thousands of workers who contributed to making Apollo 11 a successful mission.

Beautifully illustrated, this story recounts one of the greatest scientific achievement in the history of the nation. Fans of history and of space will appreciate the quality and specificity of the drawings, and will enjoy cheering for the men and women of NASA as they fulfill President Kennedy's mission.

The End of Everything (Astrophysically Speaking).

Mack, Katie. The End of Everything (Astrophysically Speaking). 2020. 240p. ISBN 9781982103545. Available at 523.1 MAC on the library shelves.

The End of Everything (Astrophysically Speaking)

The Big Bang is the famous beginning of the Universe, and the science of physics has been attempting to explain what happened for decades. As interesting as the beginning is, however, it pales in comparison to how the universe will end. In this cleverly written book, Dr. Mack describes the five possible deaths of the universe. 

In the Big Crunch scenario, the billions of galaxy that have been expanding away from each other reverse course and head toward each other, causing massive star collapse and destruction, the merging of galaxies, and possibly leading to another Big Bang as the universe once again reaches unimaginable pressure and gravity.

In the Heat Death scenario, the universe continues to expand, and galaxies soon find themselves the only thing floating in their range of vision, and themselves stretching out until all that remain are dead stars. Under this scenario, the universe literally dies and becomes absolutely cold. 

In the Big Rip scenario, the universe unravels like a tapestry or water evaporating in a boiling pot. Galaxies simply disappear away from our vision field, drifting further away and being torn apart as atomic bonds break down, releasing components into the void of space.

In the Bounce scenario, our universe is connected to other universes on other planes, and they periodically collide, creating a collapse and a new big bang. Of all the scenarios, this one involves strange physics and remains to be proven as a possibility.

Finally, in the Vacuum Decay scenario, the universe is torn apart similar to water draining out of a bath tub. The matter and energy that populate the universe drains away, filling the vacuum and bringing it to equilibrium, but in the process destroying everything that existed prior to the vacuum. Of all of the scenarios presented, this one is the most unlikely to happen, but, also unlike the other ones, it could happen at any time.

Fans of science will appreciate the humor and attention to details in this book. And not to worry, it is not filled with equations that will hurt your head, but rather vivid description and an engaging discussion of how the universe will eventually end. For a companion read, take a look at Astrophysics for People in a Hurry.
