"A Brief History of Black Holes and why Nearly Everything You Know About Them is Wrong" by Becky Smethurst

 


Publisher: McMillan
Copyright: 2022
ISBN: 9781529086706

This book is an excellent overview of the history and current state of knowledge of Astronomy, Astrophysics, and black holes in particular. It is well written, very informative, and should appeal to many readers.

Dr. Smethurst takes the reader on a historical as well as contemporary look at how black holes were discovered, and the people who did the discovering. She also takes the reader on an astrophysical journey that explains numerous other concepts that are barely touched on in a lot of other books.

Her first book "Space at the Speed of Light: The History of 14 Billion Years for People Short on Time" I reviewed back in November 2021, and this book is a great companion that will hopefully lead numerous students towards careers in astronomy and astrophysics.

Highly recommended, a great addition to any library.

"End Times: A Brief Guide t the End of the World" by Bryan Walsh

 



Publisher: Hachete Books
Copyright: 2019
ISBN: 9780316449601

This books was an extremely interesting read, that covered a lot of territory and gives the reader a lot to think about. The author is a former correspondents, reporter and editor for Time Magazine. He reported on from over 20 countries on science and environmentally focused stories such as SARS, global warming, extinction and other topics.

The book itself takes a look at eight different scenarios that could end the world, or at least the world as we know it. The first is an asteroid collision such as what wiped out the dinosaurs, and which will happen again eventually. The second is the supereruption of a volcano such as the explosion of what is now the island of Sumatra when the mountain called Toba exploded some 74 thousand years ago and essentially turned day into night for many parts of the world. The ash of Toba was found in areas such as the Indian Ocean, China Sea, Arabian Sea, Lake Malawi in Africa.

The third potential disaster is from nuclear armaments and how some rather unstable world leaders could easily be poised to commit horrendous acts. (Looking at you Putin!) Climate change is the next topic discussed, and even though a significant number of people in the world turn a blind-eye towards the facts, it seems pretty obvious to most that it is. Disease is the next topic, and discusses world-wide epidemics. It seems rather ominous that when this book predicts an epidemic of some kind in the near future when it was written, and that the world is now recovering from one. This topic merges quite well into the next one which is biotechnology, and discusses the possibility that a disease could actually be engineered.

Chapter five deals with Artificial Intelligence and what we could experience in the future if we keep increasing our computer capacity etc. at its current rates. It speculates on what would need to happen, and what the consequences might be, even though it likely won't be anything like "The Terminator" franchise. Personally I believe a better comparison would be the 1970 movie "Colossus: The Forbin Project".

Chapter six deals with Aliens, and while it doesn't deal too much with what might happen if they were to show up, it does go into a fair amount of detail with regard to our searching for them, including the history of SETI (Search for Extra Terrestrial Intelligence) and it's off-shoot METI (Messaging Extra Terrestrial Intelligence). 

The final chapter deals with the aftermath of a potential catastrophe and how we might recover. It too goes into a fair bit of detail with regard to how people believe things will unfold and the measures they take to prepare for them. I (and most others) have heard about the survivalist movement, but I wasn't aware there was such a thing as "Doomsday Preppers" who actively plan their lives around the end of the world.

This book, while it was somewhat depressing a couple of times, is a definite eye-opener to how fragile the existence of humans, and all other life on Earth actually is. The fact that asteroids have collided with this planet, super eruptions have occurred, that we have been close to a possible nuclear confrontation in the past and might be again if certain world leaders don't wake up. That we are going through climate change right now, and are hopefully coming close to the end of a world-wide epidemic doesn't bode too well for the survival of our species. After all this only leaves AI and Aliens, which is kind of worrisome.

This is the type of book we need to see more of. Highly recommended.

"Welcome to the Universe: An Astrophysical Tour" by Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott

 


Publisher:  Princeton University Press
Copyright:  2016
ISBN: 9780691157245

This was an amazing book that gives the reader an in depth look into the science of astrophysics. The three authors have written their sections in a clear and concise way that explain the concepts very well, and easily gets the message across.

In the first part  Dr. Tyson takes the reader on a study of the stars, planets and life in ten chapters that deal with a number of important concepts including explanations of the size and scale of the universe, Newton's Laws,  The lives and deaths of star, the classification of solar objects (e.g., Pluto) and the search for life.  Dr. Strauss then takes over and takes about galaxies in six chapters which include the Milky Way itself, our place in the universe, quasars, black holes, etc. Then Dr. Gott adds eight chapters in the third section that talk about both the general and special theories of relativity, black holes, string theory, the big bang, etc.

This was an extremely interesting  book to read, and even though it is a few years old at this time the information is still very relevant and should be of great value to anybody interested in astronomy or astrophysics. In addition, it is easily readable, and I believe would be a great addition to all school libraries, and would also make an excellent introductory text for first year university students.

"The God Equation: The Quest for a Theory of Everything" by Michio Kaku

 


Publisher: double day, New York
Copyright: 2021
ISBN: 9780385542746

This is an extremely interesting book, that would make a fantastic introduction to high school or first year university students into the history of physics. In reading this book I have learned a lot that I probably should've learned many years ago when I took physics. Mind you that was a long time ago, and since then the strides that have been made in the field have been huge.

Dr. Kaku takes us on a journey through the history of physics by explaining the idea of unification, Einstein's search for unification, the rise of the quantum theory, a possible theory for almost everything, dark matter and dark energy, and finally string theory.

Throughout the book he explains the concepts extremely well and in plain language that virtually everybody will understand.

I haven't read any of his books previous to this but will definitely be on the lookout for the other nine he has written in the last few years.

"Space at the Speed of Light: The History of 14 Billion Years for People Short on Time" by Becky Smethurst


 

Publisher: Ten Speed Press
Copyright: 2020
ISBN: 9781984858696

Dr. Smethurst examines and number of fundamental questions, that I'm fairly sure many astrophysicists get asked many times during their career. Some of these questions are why does gravity matter, what was around in the beginning, a history of black holes (her speciality), the overall size of the universe, alien existence, and why is the sky dark to name but a few. The chapters are well written, and give good explanations, and would be suitable to inclusion in any grade school library.

In addition of this book Dr. Smethurst is a popular YouTube personality who examines unsolved cosmological mysteries, space news in general. She also contributes videos to other YouTube channels such as Sixty Symbols, and astronomy videos to Deep Sky Videos.

"How We'll Live on Mars" by Stephen L. Petranek

 


Publisher: TED Books
Copyright: 2015
ISBN: 9781476784762

This book is extremely informative and provided the source material for the docu-drama "Mars" which gives a fictional review of what might be encountered by astronauts going to the Red planet, interspersed with an examination of the current rather sad state of the space program.

Mr. Petranek begins with a basic overview of the space program from its impetus to approximately the 1980s. He deals a fair bit of time with Werner von Braun’s proposal “Das Marsprojekt” for missions to Mars that he began promoting in 1948 (I’ll be looking for a copy of this book as it sounds fascinating). After this he goes on to outline a very logical and in my opinion workable method of how we might actually make it there, and  why we should go.

A portion of the main narrative revolves around the work of Elon Musk and his Space Exploration Corporation aka SpaceX, but Mr. Petranek also looks into the various big questions such as will a small group of people be able to get along with each other, is anybody willing to pay for the project, the safety of the project, effects of prolonged exposure to micro-gravity, medical issues that might come about, and lastly the radiation the astronauts will be exposed to.

He then goes on to look at the economics of the project, the factors that will have to be taken into account if astronauts actually want to live on Mars, terra-forming, and other topics.

The only thing in this book that I found detracted from the overall plan is that it was written in 2015, and in the 6 years since then a number of major advances have been made, so it is hoped that the author will consider writing an updated second edition.

"Time Travel" by James Gleick

 


Publisher: Pantheon Books
Copyright: 2016
ISBN: 9780307908797

    This was an extremely interesting book to read, as it began with an examination of the phenomena created by H. G. Wells when in wrote "The Time Machine" in 1895, and then went on to look at how it has been treated in other stories. Mr. Gleick also reviews the science behind time travel, as well as the philosophy of it as well.

    To say that the concept of time travel is a staple of science fiction as some authors have said is, I believe, an exaggeration as Wells was the originator of the concept, and science fiction itself existed for a considerable time before he came on the scene, even though it went by other names. 
Mr. Gleick looks at a number of different topics related to time travel such as: the concept of time itself, paradoxes, how time flows, etc.

    Mr. Gleick's research on this topic was extensive, and I am looking forward to reading some of his other books, as if they are even half as good as this one they should be well worth it.

"T-Rex and the Crater of Doom" by Walter Alvarez


 

Publisher: Princeton University press
Copyright: 1997
ISBN: 9780691169668

I have been working in the field of palaeontology for 10 years now, and even prior to that likely since I first heard about it in the 1980s, I have always excepted the fact that a meteor or a comet had spelled the end of the era of dinosaurs (otherwise known as the Cretaceous), and that it had hit on what we now know as the Yucatán Peninsula.

I was unaware however of all the research, and the years it took for Walter Alvarez, his father Luis Alvarez, and scores of other scientists to prove that this had actually occurred. This book takes you on an absolutely enthralling journey of how the discovery was made.

The first chapter takes you back to a world 65 Million years ago, just before the Cretaceous era was about to abruptly end. It describes in detail what must have happened on that fateful day when either a comet or meteor approximately 10 kilometres across slammed into the Yucatán Peninsula. There was no warning as it was travelling at an estimated 30 kilometres per second (about 150 times faster than your typical airliner).

Between the time it first touched the Earth's atmosphere and it hit the ground, only 1 second had elapsed.

Dr. Alvarez'sstyle of writing makes this a very easy book to read, and provides the reader with a close look at exactly how the scientific method works, and should be required reading for anyone interested in the scientific method regardless of their discipline, as a great many people don't really seem to realize all the work that has to go in to actually examining a hypothesis, and subsequently proving a theory, or the amount of time it can take to do it.

A great book, I'm kind of sorry it took me so long to getting around to reading it.

"First Man: The Life of Neil A. Armstrong" by James R. Hansen



Publisher: Simon & Schuster
Copyright: 2005, (3rd Edition 2018)
ISBN: 978-1-9821-0316-3

I found First Man to be an extremely informative and engrossing biography of the astronaut and Apollo 11 commander Neil A. Armstrong. I can vividly remember sitting on the floor of our basement family room listening to a black & white television in July 1969 when the Moon Landing was broadcast on CBC (the only station we could get). I was fascinated then, and still am today. Hopefully someday humans will return to the Moon, and possibly venue further into space.

The book essentially details Armstrong's life from birth in 1930 to his death in 2012, and gives a very detailed examination of his career in the United States Navy, and has a test pilot prior to becoming an astronaut, his accomplishments in the Gemini, and the Apollo programs, and his life after returning to Earth.

Commander Armstrong was an extremely private individual, but one who was forced into the public eye due to the accomplishments of the crew of Apollo 11. It was quite evident throughout the book that he did not like all the public exposure, but he did his best to survive it. Unfortunately this did cause a great deal of stress in his life, and to his family.

The accomplishments of Michael Collins, Buzz Aldrin, and Neil Armstrong will go down in history as one of the greatest feats of engineering, courage, and dedication the world has ever seen. But without the 400,000 plus people at NASA and various other agencies and companies the accomplishments of these three men would not have been possible.

Prior to reading the book I did watch the movie, and found it to be equally as interesting, even though the director did take some liberties.

I would highly recommend this book to anyone who is interested in reading a well written and researched biography.

"Star Talk" with Neil deGrasse Tyson



Publisher:Washington, D.C. : National Geographic, [2016]
Copyright Date:©2016
ISBN: 9781426217272
Characteristics: 302 pages :,colour illustrations

"StarTalk" is the companion book to the radio show and television program. It is hosted by Dr. Neil Degrasse Tyson of the Hayden Planetarium in New York.

The book itself is not a transcript of what took place on the radio or television program. It is more of a coffee table style of book that touches on numerous subjects and gives very concise explanations with regard to why they are true or untrue, work or don't work, and it debunks a number of myths as a bonus.

It is separated into four major sections space, planet earth, being human, futures imagined. It each of these there are 5 to 6 different sub-topics. For example in the space section there are discussions entitled: What do I pack for Mars? What do I eat in space? Can we use wormholes to travel? Who goes there? And are we there yet?

Each of these subtopics is then broken down into smaller discussions with contributions from authors, experts in the field, celebrities and so on.

This is an extremely good book, that is designed to answer questions that a teenager or younger child will have about various topics related to science. It would also be a great resource for students up to high school to stimulate their curiosity, or give them ideas for research paper topics.

I personally have not listened to the radio program but the television program which is produced by National Geographic is extremely interesting and quite humourous at times as well.

"Artemis" by Andy Weir

Artemis



Publisher:New York : Crown, [2017]
Edition:First edition.
Copyright Date:©2017
ISBN: 9780553448122
Characteristics: 305 pages :,illustrations ;,25 cm

Artemis is Mr. Weir's second novel, and he has followed up "The Martian" with another great story. I believe this one would also make a great movie in the event someone from Hollywood happens to be reading this blog (yeah, right!). As it has the elements of a great adventure story, with political intrigue, a strong protagonist, and much more.

The story revolves around a lunar resident by the name of Jazmine Bashara who seeks out a living (not always legally) in the only inhabited city on the moon. Her life suddenly gets very interesting however, when she is offered an opportunity she can't really refuse. But which turns out to be a little more complicated than she planned on.

Mr. Weir is one of few authors today who writes in first person, and this gives the story a very immediate feel that many novels now-a-days never get close to. Many writers seem to shy away from first person, and more writing teachers, and resource material seems to advise against using it. Now while this may be good advice for an absolute beginning writer, it is quite refreshing (in my opinion at least) to read stories told this way.

In addition, Mr. Weir definitely did a fair bit of research when planning the city of Artemis and this has really paid off, as the technology behind the story is very consistently designed, and believable.

I eagerly await his next book, as I'm sure after two hits he'll be able to keep going.

"Astrophysics for People in a Hurry" by Neil de Grasse Tyson

Astrophysics for People in a Hurry



Publisher:New York : W.W. Norton & Company, [2017]
Edition:First edition.
Copyright Date:©2017
ISBN: 9780393609394 
Characteristics: 222 pages

I really enjoyed this book and think that Dr. Tyson's explanations of astrophysics are very complete and extremely easy to understand with little math required. I'm not sure when I first became aware of Dr. Tyson's work, but I believe it was possibly during the controversy that erupted following the demotion of Pluto from a planet to a dwarf planet in 2006. I grew up in a time when we all thought that the solar system had nine planets, and now we have eight, so what? It was either that or when I saw the updated series Cosmos: A Spacetime Odyssey, which I feel is a great complement to the original series by the late Dr. Carl Sagan. If you haven't seen this series, I would definitely encourage you to do so, but would recommend that you watch the original first.

In any case, "Astrophysics for People in a Hurry" is a great book, and well worth the read. I've been a fan of space for many decades, but still learned a fair bit from this book which examines topics such as the Big Bang, Dark Matter, Dark Energy, and much more.

Dr. Tyson's sense of humour is quite unique, and adds to the fun of what some might think of as a rather unwieldily topic for a book that is marketed to the general public. His views on the viability of levitation are very interesting, and I would be very interested in seeing his equations on how this could be accomplished, and even more so in see an actual demonstration (but preferably not inside a closed room).

Going on Hiatus

 Greetings, I have decided to put a hold on doing further book reviews for a while. In fact I'm not sure if I will resume doing reviews ...
