"Paleofantasy: what evolution really tells us about sex, diet, and how we live" by Marlene Zuk

 


Publisher: W. W. Norton & Company
Copyright: 2013
ISBN: 9780393081374

Paleofantasy is a very interesting book that goes into the great detail debunking the Paleo diet and other such pseudo scientific silliness. Dr. Zuk is a professor of ecology evolution and behaviour at the University of Minnesota, and she has researched this topic extremely well.

She uses the disciplines of anthropology, physiology, psychology, medicine and history to explain why the Paleo diet is not what proponents believe it is or promote it as i.e., a cure-all for societies ills, weight loss, etc.

In this book she examines the lifestyles that proponents of the Paleo lifestyle follow, and examines how actual science debunks this system of nutrition, and living. She gives a good overview on evolution, and how it works and then examines other concepts of the Paleo lifestyle such as exercising, love, sickness and health and much more.

Dr. Zuk's writing is clear and comprehensive, and the examples she uses are easily understandable by anyone. Or at least anyone who wants to understand them, as I am sure there are many paleo-fans out there who will dispute her findings as they have little or no scientific training.

Highly recommended

"The Life-Changing Science of Detecting Bullshit" by John V. Petrocelli


 

Publisher:  St. Martin's Press
Copyright:  2021
ISBN:  9781250271624

This book was quite informative, and well worth having to wait to get my hands on. The examples, and explanations for how people are fooled, and react when presented with even subtle forms of bullshit was very well done. I've always thought that I was pretty good at detecting false claims, and other misdirections, but this book opened my eyes to a number of things that I had never even considered.

Mr. Petrocelli dives the book into a  number of different sections such as the "Costs of Bullshit" in which he discusses price markups, wine tasting, and psychological testing.  "Why People Bullshit"  in which he discusses how you can detect their lies. He then gives the reader some examples of some rather famous Bullshit Artists such as Douglas Biklen, Donald Trump, and Deepak Chopra. Following this he takes on various common examples of bullshit such as TED Talks (some of which are quite valuable, but others which are ripe examples of bullshit), and more.

Throughout this book I was presented with lots of information that was very valuable, and I would seriously recommend this title to anybody who is interested in getting to the truth.

"Relax, Dammit: A User's Guide to the Age of Anxiety" by Timothy Caulfield.


Publisher: Allen Lane
Copyright: 2020
ISBN: 9780735236325

This book takes the reader on an interesting journey though a single day, and highlights the myriad of different things that humans (yes, you!) typically worry about during that time, in the order you normally will encounter them. Most of these things were ones I'd personally never given any thought to, but upon reading about it realized that they are part of my life as well (except for the coffee part).

The book is split into three main sections Morning, Afternoon & Evening, and within each of these Dr. Caulfield examines the various things that are part of our lives. There are of course certain things that are present in all areas, such as our fascination and slavery to our cell phones, but like he says "Relax, Dammit!" Each of the topics he surveys are very informative, and for the most part addressed from a rather unique point of view, which is both enlightening, and at times quite humorous.

I don't want to spoil the read for you, but as a bit of a teaser he examines such things as waking up, weighing yourself, vitamins, parking, hand washing (something we are, or should be quite aware of in today's world), public toilet seats, coffee (yuck!), stand-up desks, soap, water drinking, the ubiquitous five-second rule, napping, hugging, television, and much more.

Dr. Timothy Caulfield is the Canada Research Chair in Health Law and Policy, as well as a Professor in the Faculty of Law and the School of Public Health at the University of Alberta, in Edmonton. He has written a two other books "The Curefor Everything: Untangling the Twisted Messages about Health, Fitness, and Happiness" and  "The Science of Celebrity ... or is Gwyneth Paltrow Wrong About Everything?"

An excellent read that will definitely open your eyes. Highly recommended. If you ever get a chance to hear Dr. Caulfield speak, take the time out of your busy schedule and do so. Also don't forget to Relax!

"Hoax, A History of Deception: 5000 Years f Fakes, Forgeries and Fallacies" by Ian Tattersall & Peter Nevraumont


 

Publisher: Black Dog & Leventhal
Copyright: 2018
ISBN: 9780316503723

Hoax takes the reader on a very interesting journey through the minds of perpetrators, as well as others who have had something to do with hoaxes, cons, etc. It is an extremely interesting read that will surprise you. In all the authors examine 50 hoaxes starting in 2800 BCE and going through to present day, dealing with such topics as The End of the Word, the myth of Noah's ark, Gladiators vs. Professional Wrestlers, various religious topics such as sacred relics, the Shroud of Turin, Priory of Sion, etc. They also cover the typical ones such as the Loch Ness monster, Bigfoot, and Piltdown Man. But in case you might think this is mainly about things that happened many years ago, they also looks at the vaccination debate, homeopathy, race, fake memoirs, fake bomb detectors, and much more..

I found this book to be quite informative, and even though I had heard of some of these topics before, others were brand new to me. The chapters are rather long, but do present the information in a well written and concise format. I can see this book being valuable to students in junior and senior high school especially considering the amount of misinformation that is present in the world today via the internet.

Well worth the read! I hope the authors consider doing a second volume as there has to be more hoaxes they didn't have a chance to cover.

"The 7 Laws of Magical Thinking" by Matthew Hutson

 


Publisher: One World Books
Copyright: 2012
ISBN: 9781851689347

Mr. Hutson is an extremely interesting author to read, and one who does a lot of research. This book is essentially about critical thinking. And he has broken down human beliefs into seven general areas.

The seven laws themselves are: that objects carry essences, that symbols have power, the actions have distant consequences, but the mind knows no bounds, the soul lives on, but the world is alive, and that everything happens for a reason.

Each of these laws in turn talks about things like contagions and historicity, spells in ceremonies, luck and superstition, psychokinesis and ESP, Life after death, animism, and destiny.

The overall premise of the book is that all people wherever they are, believe in magic of some kind. They might not define it as magic, but that is essentially what it is. The author starts out this way by giving examples of various things that people typically do that have links to magic in the past, and he concludes in the eighth chapter by returning to this.

And excellently researched book that is well worth reading and what that would hopefully be a good medium level read for somebody who is interested in critical thinking. I suggest medium level because I think people should have some Basic understanding of critical thinking and what is required prior to starting this book.

Highly recommended.

"Crimes Against Logic" by Jamie Whyte



Publisher: McGraw-Hill
Copyright: 2003
ISBN: 9780071446433

Mr. Whyte takes a very interesting and revealing look at how statistics, logic, and various arguments are misused by politicians, the clergy, journalists, and various other repeat offenders.

He covers various topics starting with a discussion of whether you have the right to your opinion, goes on to cover motives, the authority empty words, looks at begging the question, the existence of coincidence, the use of empty words, the misuse of statistics, and finally a look at morality. In all cases he gives very relevant, humourous, and in many cases eye-opening examples (that most people wouldn't typically consider) of what he means and this allows the reader to understand the points that he makes that much better.

This isn't a long book but it is a very interesting read that definitely shows the reader how they are being guided into thinking things that are not true, especially when dealing with politicians, the clergy, and most recently journalists. At times this is being done intentionally by the politicians and at times the clergy. While under other circumstances a journalist is guilty of it because they simply do not understand statistics or in some cases choose to ignore statistics or facts in favour of getting a good story.

A great book that should be read by all.

"Demon Haunted World: Science as a Candle in the Dark" by Carl Sagan (1934-1996)



Publisher:New York : Ballantine Books, 1997.
Edition:First Ballantine Books edition.
Copyright Date:©1996
ISBN: 9780345409461
Characteristics: xviii, 457 pages ;,21 cm

This book takes an in-depth look at what humans believe, why we believe it, how we are led to believe certain things, the consequences of us believing them both good and bad.

Dr. Sagan was a very famous popularizer of science, one a few in the field. His explanations are very clear, but his amazement at how people can be bamboozled, and led astray definitely comes through in his writing. But then again this was his goal in writing this book.

He goes into a great deal of detail with regard to the history of skepticism, and gives the reader very good examples with regard to ways in which people nowadays can easily detect when they are being taken advantage of.

I found this book to be a fascinating read, with literally tons of valuable information regarding history, current scientific methodology, the way unscrupulous practitioners deal in their trade, etc. It is a no holds barred look at what people in the past and present believe, why they believe it, how they were led to believe it, and unfortunately in many circumstances why they refuse to believe the truth when it is revealed to them.

Highly recommended.

"The Skeptic's Annotated Bible" by Steve Wells



ISBN: 9780988245105 (hardcover)



Ever since the attacks of September 11, it has been repeated many times in both the mainstream media, and in casual conversation about how violent and war like the Koran is.

Sources that this espouse this viewpoint seem however to have blindly ignored all the violence, the subjugation of women, racism, murder, sexual deviation, and genocide (amongst other things) that are present in the Christian Bible.

The three Abrahamic religions namely Christianity, Islam & Judaism all stem from the same roots, and while it is possible that both the Talmud and the Koran also promote violence, the subjugation of women, racism, etc. I am unable to confirm this because I do not speak or read either Arabic or Hebrew, and I would be somewhat sceptical of an English translation of them, as translators throughout history have been infamous for massaging texts to suit their philosophies.

There are however some things you have to ask yourself: if the Christian Bible is truly the word of a benevolent god, then why is it so violent, why does it vilify women, promote racism, glorify genocide, and so on ad nauseum. Yes, it can be argued that this is the way things were back then, but if that's the case then why are we supposed be following the dictates of a misogynistic, racist, genocidal supreme being, with an inferiority complex to deep that if it isn't worshipped that it will take revenge on everyone?

Unfortunately most people simply pick and choose certain parts of the book, blindly ignore the rest, and are quite happy in their ignorance, and justify away their choices by saying that's the way it was.

In any case the contents of this book should make any critically thinking person take a second look at what the Bible actually does promote.

"Sexual Intelligence" by Kim Cattrall


Publisher: Greystone / Madison Press Books, New Video Group (DVD)
Copyright: 2005 (Book), 2006 (DVD)
ISBN: 1-55365-105-7 (Book), 0-7670-8772-0 (DVD)

Ms. Cattrall first wrote the book and this inspired the documentary. According to her the reason for writing the book: "For me, it was a desire to define myself beyond an iconic character I played for over seven years - a character I love and fully embraced. Samantha Jones captured people's imaginations and earned a place in our collective culture."

The book and documentary interviewed a number of professionals with regard to their work in the areas of sex education, their thoughts, and feelings, etc. Three of the professionals consulted: Thomas Moore "The Scale of Sex", Michael J. Bader "Arousal", & Maggie Paley "The Book of the Penis" have each published on the topic and are considered authorities in the field. In addition the renowned sex therapist Betty Dodson gives her input from a medical point of view. Six non-professionals are also featured in the documentary and a seventh is included in the book, and all candidly tell their stories and give their opinions on how they feel about sex in general and with regard to specific topics.

Comprehensive and accurate sex education is something that is severely lacking in North American society, and unfortunately even more so in other cultures. The vast majority of today's youth have a very lopsided view of what sex actually is, as they are getting their information from a number of sources such as religious institutions, the internet, pornographic videos, etc. The vast majority of these are less than credible, after all how are religious practitioners - that supposedly practise abstention - supposed to give accurate information about something they shouldn't even know anything about? As for the internet, well that is likely the worst place to get accurate information as on there every male is so well endowed that he should probably invest in training wheels, those who aren't are told they should be and tons of ridiculous potions, pills, and other concoctions promise that he will be in a matter of days. For women, they are all supposedly ready for intercourse at the drop of a hat, have to be cleanly shaven, and have enormous breasts.

The book and DVD give a very good introduction to the history of sex, its representation in the arts (both historically and contemporarily), how it is seen in other cultures (primarily historically - in such places as Pompeii), and in basic sex education. Hopefully this inspires readers and viewers to investigate the topic further. The book contains an extensive bibliography, and this alone is worth the price of the book.

As the book asks "Is it possible to develop a kind of sexual intelligence, one that can deepen our pleasure and give us a greater awareness of ourselves?" If a reader takes this to heart and continues to read from reputable sources on the subject then I would say it is possible, but it is something that a person will have to work at.

"Sapiens: A Brief History of Humankind" by Yuval Noah Harari



Publisher:[Toronto] : Signal, 2014.
Copyright Date:©2014
ISBN: 9780771038518 
9780771038501 
Characteristics: 443 pages :,illustrations, maps

This is an excellent book that is well worth the praise that it has garnered to date. It covers areas as diverse as politics, history, religion, economics, and much more in a well researched and very understandable format.

The author's writing style is very refreshing with the odd bit of humour thrown in to keep the reader interested. Even though the style is easy to read, the topics covered are quite complex, but this will hopefully not dissuade anybody from reading it.

I would recommend this book to anybody who is looking for a good overview of human history, and what we've managed to accomplish in the 100,000 years or so. It would also I believe make a good addition to a senior level courses in anthropology or sociology as it analyses their disciplines from a layperson's standpoint.

Definitely a book I'll be adding to my collection!

"Dinosaurs of the Alberta Badlands" by Dr. W. Scott Persons IV

Dinosaurs of the Alberta Badlands


Publisher:Harbour Publishing, 2018
Edition:First edition
ISBN: 9781550178210
Pages: 144
Includes glossary, index

This book is a great introduction to the world of palaeontology for students, as well as their parents. Dr. Persons spent a great deal of time crafting the text to make it enjoyable to read, and I believe it will delight anybody who picks it up.

The book covers a wealth of topics in an easy to read format, with lots of illustrations (by Dr. Julius Csotonyi) and photographs which help to explain the various topics and concepts. Some of the topics covered include why Alberta is such a perfect place for palaeontology, how fossils are found, how the age of the fossils is determined, how evolution works, how fossils are safely extracted and prepared, and much more.

Interspersed throughout the book he also gives brief biographies of some of the palaeontologists that have worked with him in the Badlands and other parts of Alberta such as Drs. Philip Currie, Angelica Torices, Victoria Arbour, Eric Snively, Michael Burns, and Ryan McKellar. Readers also get to read about various dig sites and find out what is so special about them. Another section examines the various dinosaur species that were common, and are typically found in the Badlands, and other parts of Alberta.

This isn't a large book, but it would be a valuable one for any school library to have in their collection as todays elementary and junior high students are tomorrow's palaeontologists. The final section of the book details what a current students needs to know, and what's they'll need to specialize in if they want to be a palaeontologist.

"Everyone is African: How Science Explodes the Myth of Race" by Daniel J. Fairbanks

Everyone is African: How Science Explodes the Myth of Race


Publisher:Amherst, New York : Prometheus Books, 2015.
ISBN: 9781633880184
Characteristics: 191 pages : ,illustrations ;,23 cm

Having taken quite a number of anthropology and biology courses during my university training, I already knew that racism as a constructed concept that was based on the supposed superiority of certain groups of people. Dr. Fairbanks however was not writing his book for me, but was doing so for the rather large percentage of the population that hasn't already grasped this concept.

Dr. Fairbanks goes into great detail, but in a very readable way that explores the genetic, historical, and various other aspects of racism and hopefully puts them to bed for good. His discussion of topics such as: What is Race, African Origins, Ancestry versus Race, Skin Colour, Diversity and Health and Intelligence, and finally the Perception of Race covers this topic in a thorough manner that really should convince even the diehards, and leave everyone more enlightened.

Unfortunately, as is typically the case when dealing with humans there will always be certain factions (primarily religious, or other insular group) that will refute his explanations. There is likely nothing that intelligent individuals can do about these types of people except pity them in their ignorance, and help them as best we can in doing simple tasks like wiping their noses.

Yes, I know the above sounds very condescending - it was meant to be. I have no tolerance for racism, and even though I was exposed to it rather frequently as a child, I try to combat it as best I can in my daily life. Hopefully I'm succeeding.

"The Discoverers" by Daniel J. Boorstin

The Discoverers: A History of Man's Search to Know his World and Himself

Daniel J. Boorstin (1914-2004)
Publisher:New York : Random House, [1983]
Copyright Date:©1983
ISBN: 9780394726250
Characteristics: xvi, 745 pages ;,24 cm

The overview of this book says that it is "An original history of man's greatest adventure: his search to discover the world around him. In the compendious history, Boorstin not only traces man's insatiable need to know, but also the obstacles to discovery and the illusion that knowledge can also put in our way. Covering time, the earth and the seas, nature and society, he gathers and analyzes stories of the man's profound quest to understand his world and the cosmos."

This book is one of three Mr. Boorstin wrote in this same vein, the others being "The Creators" and "The Seekers".I haven't read either of these yet, but they are on my list, and will be reviewed in time.

The Discoverers was a fascinating book, and even thought it took me a long time to read it (684 pages of text) it was well worth the time. I believe this book (and possibly the other two mentioned above as well) would make fantastic texts for a history or anthropology class at the University level. Granted that the majority of students might not read them, but those that did would benefit immensely from the information to be gained.

The book is separated into four major divisions Time, The Earth and the Seas, Nature, and finally Society. Within each of these are sub sections that breakdown the divisions into more manageable works. These are sub sequentially separated into chapters dealing with a specific idea.

The detail with which Mr. Boorstin was able to present this information is wonderful. An example of this from the section of Time is: "Part I: The Heavenly Empire" which deals with rudimentary astronomy and it relation to astrology and how it was connected with religion and how they all influenced various historical events.

"Part II: From Sun Time to Clock Time" traces the development of time keeping through its many phases. Including Calendars, Sun Dials, Clocks, Time Keeping at Sea which allowed for the determination of longitude, etc.

I could go on and give an overview of the entire book, but then you wouldn't have to read it, which is something you should definitely do! All in all this was a great book, and I'm looking forward to reading the next ones in the series, however I won't be reading them right away as it will take me a while to digest all the information presented in this volume.

"Superfreakonomics" by Steven Levitt & Stephen J. Dubner

Superfreakonomics


Publisher:New York : William Morrow, [2010]
Edition:First edition, illustrated edition.
Copyright Date:©2010
ISBN:9780061941221



Characteristics:xxi, 281 pages :,color illustrations ;,27 cm


Superfreakonomics was a delight to read, as well as being very informative. I had read Freakonomics a few years ago and found that it too was well researched and well presented (however this was before I started writing reviews on this blog). I never took any microeconomics courses while I was in university but a book like this makes me wish I had done so.

The in depth examination of the Kitty Genovese murder was very interesting to read. My first exposure to this tale was during one of my psychology course at University, and like is mentioned in Superfreakonomics it was the standard telling (accounts from the regular news media), and that was many years after the fact as I was very young when it happened. The information provided in this book however sheds new light on the subject and makes you pause and think, rather than just be abhorred by the the bystanders did (or in this case didn't do).

Two other chapters that were very thought provoking was the one on global warming and the final one about monkeys. I would definitely like to hear more about the monkeys!

One criticism I have though is that when you consider that Canada is the Northern neighbour of the United States, and that we share the longest undefended border in the world. It seems odd to not see any mention of our existence in the book, mind you this is rather typical to a certain point in pretty much all books published in America so I guess I can't fault them on that (well, not too much at least).

All-in-all a very good book worth taking a good look at, you do tend however to want to read a whole chapter at once (and they're fairly long) so brew a big pot of tea and go to it. For sake of clarity I would recommend that you only read one chapter per day (or however long it takes, as there is a lot of information to absorb), and then sit back and reflect on what you have read.

"How to Fake A Moon Landing: Exposing the Myths of Science Denial" by Darryl Cunningham

How to Fake A Moon Landing: Exposing the Myths of Science Denial


Publisher:New York : Abrams ComicArts, 2013.
ISBN:9781419706899  

Characteristics:172 pages, 4 unnumbered pages :,color illustrations
Alternative Title:Previously publushed as: Science tales: lies, hoaxes, and scams.
This book explores eight common science denial areas in cartoon format, and does it very well. Mr. Cunningham deals with the topics: The Moon landing hoax, Homeopathy, Chiropractic medicine, Vaccinations, Evolution, Fracking, Climate Change, and General Science Denial as does so in a way that will appeal to people of all ages.
A quote from Michael Specter a staff writer for the New Yorker as well as an author states the overall thesis behind this book on page 2 by saying:
"Everyone is entitled to their own opinion; however, everyone is not entitled to their own facts."
The eight myths contained within this book are all refuted, by reviewing them in a rational, and logical way with simple explanations as to why they are false and providing the scientifically based reasoning behind the evidence.
While I'm sure this book won't convince the die-hard science denial fans, it will hopefully at least start to drive a wedge into their armour and therefore show everyone that their one sided opinions are not sustainable in a rational discussion.
Another quote, this time from the preface:
"... [T]he universe has amazing and strange qualities anyway for those who care to see them. There is no need to believe in fantasy in order to see the extraordinary in the world, when reality offers up so much that is astonishing." (pg. 6)
Pick this book up, and enjoy it.

More Science in Movies

I my last posting I tore a strip off Star Trek, and while I think in most respects it does deserve it there are other shows that are worse with respect to science. Now the reason I'm going soft on Star Trek is simply because under a number of different definitions of Science Fiction it doesn't fit. Why? Because dear reader many people who have gone and bothered to define Science Fiction say essentially that it is fiction where  science is a major necessity in the plot. Or as Theodore Sturgeon says: "A good science-fiction story is a story about human beings, with a human problem, and a human solution, that would not have happened at all without its science content". And due to the lack of science content, or rather all the liberties taken in writing that have been disguised as science I don't believe it should qualify.

Now because I've given Star Trek a rather good beating, it's time to point out that this same problem exists with virtually every "science fiction" movie that has been made for many years. In fact this is the case with most movies and television shows that come out now-a-days (not just the science fiction ones). The lack of an understanding of basic science (either willfully, or simply through sheer laziness/ignorance) by the writers, directors, and many other technical staff that contribute is simply astounding. I'll go into these details in a later column, but for now I'd like to point out that this disregard for science is not wholly a problem with television and movies. Many books suffer from this same problem. And as a writer of Science Fiction stories I feel that this is important (otherwise I probably wouldn't be writing this - go figure).

So what's my beef?

Why do many science fiction authors seem to make no attempt (or very little at least) to incorporate science into their stories, and when they do why do they frequently get it wrong?

Okay, so the first thing you might say is "well it is fiction!". Okay point taken, but if you aren't going have any science you might as well call it a fairytale, and not science fiction. Back up in the first paragraph I quoted Theodore Sturgeon, here are a few other quotes that define science fiction:

Robert J. Sawyer: "Science fiction is the mainstream literature of a plausible alternative reality."

Barry N. Malzberg: "Science fiction is 'that branch of fiction that deals with the possible effects of an altered technology or social system on mankind in an imagined future, an altered present, or an alternative past'."

Sam Moskowitz: "Science fiction is a branch of fantasy identifiable by the fact that it eases the "willing suspension of disbelief" on the part of its readers by utilizing an atmosphere of scientific credibility for its imaginative speculations in physical science, space, time, social science, and philosophy."

John W. Campbell, Jr.: "The major distinction between fantasy and science fiction is, simply, that science fiction uses one, or a very, very few new postulates, and develops the rigidly consistent logical consequences of these limited postulates. Fantasy makes its rules as it goes along... The basic nature of fantasy is "The only rule is, make up a new rule any time you need one!" The basic rule of science fiction is "Set up a basic proposition--then develop its consistent, logical consequences."

Likely the best definition of those above is the one from Campbell, which seems pretty simple to me. Unfortunately it seems to slip the minds of many science fiction authors. Now granted there are various sub-genres of science fiction such as "hard-science fiction" which usually does a very good job of getting it right, but it's not these authors that I'm whining about. Its the author who says "I write science fiction", but who has no idea what science is.

I've already talked a lot about Hollywood and how it's famous for this and maybe this is where these authors get their ideas. Now if a person had never seen anything from NASA, had never read Scientific American, or seen Discovery Channel, etc., and was basing all their science on "Star Wars", "Star Trek", "Jurassic Park", and any number of 1950s & 60s "B" movies you'd probably have to cut them some slack, but I doubt there are many of these people around. A couple of prime examples from this era are "Them" (1954) and "Attack of The Fifty Foot Woman" (1958). Sorry folks, but neither the ant's nor the lady's legs would have been able to support their respective bodies, bone simply isn't strong enough. In other words some of the science that is violated is so simple as to make the authors essentially look like fools (or worse).

The written word however is vastly different, after all how many times have you read a book, then seen the movie and thought it was crap? That's because the written page can contain so much more detail, and because of that the author has to do that much more research (or they should at least). Now granted compressing a couple of hundred pages of text into a movie is no mean feat, but still …

I'm going to continue on with this theme next time and give you some illustrations on some of the problems and maybe even how to fix them if you're interested.

Science in the Movies (and television).

So far we have covered two very important parts of why it is very unlikely we have ever been visited by extraterrestrials, namely: first was the distance, and second why would they bother to come here. There have been literally thousands of television programs and feature films that fit the very broad description of "Science-Fiction" (over 5000 in fact according to IMDB) however, how many of them are scientifically accurate? Most are nowhere even close, and a great number do science such a disservice that they should really be classified as something like pseudo-science fiction. There is no way of classifying all the errors that some of these shows make, but the majority are things that any junior-high school student (and likely some elementary ones as well) know are not correct.

One of the biggest blunders that is continuously made is the sounds in space. Very elementary problem here - in order to have sound propagate you need air, and there is none in space so therefore there can't be any sound. The only movie I can think of off hand that got this right is 2001: A Space Odyssey. This same thing goes for explosions. "Bang" is a sound and therefore if there's no air there's no bang. This is taken to absurd lengths in virtually all films, and now-a-days when every space film seemingly has to have a battle sequence. Okay, I assume you get the point so I won't harp on it any longer.

Another problem that is very common in these films is that every alien is a bilaterally symmetrical biped, with stereoscopic vision (two eyes, both facing forward), two arms, etc. With the exception of the Star Wars series - which admittedly still lots of those good ol' bipeds there was at least a number of other aliens present (Jabba the Hut comes to mind). Now you'd think that with the huge budgets that Hollywood has for their films that they could do something a little original. Probably the biggest violator of this is the Star Trek franchise in which not only are they virtually all bipedal, but in some cases the difference between alien races is simply a few bumps on the forehead. In fact I can only recall one alien in the original series that looked alien and that was the Horta (an acidic rock dissolver, that looked like a large pepperoni pizza with extra cheese). Now admittedly I am not a Trekkie, and I haven't seen any of the newer episodes but with seventy some episodes in the original series and only one alien-looking alien the odds aren't too good that they've had any original thoughts since.

I don't want to harp on the silliness of Star Trek too much more, but they take things to absurd limits by not only making virtually all the aliens look the same, but also allowing them to interbreed. Come on people this is really basic biology. The prime example of this silliness is Mr. Spock. Why is it silly? For starters he is supposedly an alien, whose bodily chemistry is based on copper (not iron like ours), his parent's Amanda & Sarek - yes I had to look this up - mated (with a little genetic help it is stated), and successfully conceived a child. Now the chances of this happening (even with significant genetic assistance) is about as likely as a human successfully mating with a rose and producing a either living person that would never have to use deodorant, or a flower that can do calculus. Why, after all they did say there was some genetic help? Simple the two races have a different body chemistry (copper vs. iron remember), different chromosome numbers (humans have 23 vs. Vulcans' have some other number), different gestational periods (nine months vs. who knows what), etc. etc. ad nauseum. It was stated at one point that all races in Star Trek evolved from an ancient one, but this is absurd as well as basic evolutionary law says that species that are isolated will eventually be incompatible mates with other species. So enough about Star Trek.

So come on Hollywood lets see some science in your science fiction! Mind you when it comes down to it there hasn't been much original work come out of Hollywood for many many years so I guess the chances of anything like this happening is pretty slim.

But Why Would They Come?

Okay, so we can all likely agree that the other stars are a long way from here. But if we ignore this by saying that another civilization is using multigenerational ships to travel say something like what I'm assuming they were trying to portray in the movie "Independence Day". I say assuming as they definitely didn't saying anything about faster-than-light drives, etc. and the only time we saw the mother ship is was either moving at a relatively normal speed for spacecraft, or it was in orbit (yeah I know this is assuming a lot but I figure they didn't mention it so we can ignore it). So for sake of argument an alien race shows up in our stellar neighbourhood, the big question would be why would they bother to come here in the first place?

Let's face it human's aren't exactly going to attract any other civilizations. We've only had the ability to transmit data electronically for under 100 years (1907 for radio, 1918 for television). These first broadcast signals were very weak compared to what w have today so we can likely shave a fair number of years off these as well as by the time they got out into space any distance their signal strength would be extremely weak. So for sake of argument let's say that we have been transmitting for seventy years at a decent signal strength to reach anybody who might be listening - that puts us in 1942.

So sometime in the last seventy years a spacefaring civilization picked up our signals, and figured out what they were. After all not only would the signal strength be very weak, but whoever was listening wouldn't know any of our languages. But is we assume that they puzzled out that they were from an intelligence race of beings and decided to visit then we have another problem, which relates back to the previous posting I made, and that's distance and consequently the speed their ship can travel at.

In order for extraterrestrials to be visiting us today in 2012, and assuming they left home as soon as they detected the signal (the ships were ready to go all they had to do was shut the hatch and step on the accelerator), and further assuming they can travel at the generous speed of ten percent of the speed of light then that means the furthest away they can be from us is three point five light years (which would give them a thirty-five year journey). If by some chance they can get extremely close to the speed of light (by the way I am intentionally ignoring the time dilation effects) then this allows them to be further away but only thirty-five light years. But why do I say thirty-five is the maximum?

I set thirty-five for a maximum because I first assumed we have only been transmitting for about seventy years. Which means that the signals from 1942 are just now reaching the vicinity of Zeta Lepus (which happens to be 70 light years away), but even if a ship left there right now, it wouldn't get here until 2082 if they could travel at light speed (or close enough not to matter) and that's seventy years from now. So we're back to thirty-five year issue (thirty-five for the signal to get to them, and thirty-five for them to get to us - remember we're assuming they can travel close to light speed).

But once again why would they come? Thirty-five years ago the signals that were coming from good ol' Mother Earth were things such as "It's Your First Kiss, Charlie Brown", "Eight is Enough", "Soap", "CHiPS", and "The Love Boat" - not exactly anything that would attract an intergalactic civilization - unless of course they were intergalactic police, and wanted to protect the citizens of the galaxy from extremely poor quality writing (okay, Soap was relatively good, but the rest give me a break!).

You'll have noticed by now that I used the word "if" a lot in this article, and that is because there are a lot of questions that need answering (I mean other than why did "The Love Boat" last for nine seasons?). Also remember in the last couple of paragraphs I assumed that these supposed extraterrestrials could travel at just under light speed, which isn't likely. I'm not saying it impossible, but the technological leap that would have had to be made is a little hard to swallow.

Classification and Critical Thinking

As you may have read in my last post there are many ways for classifying a given group of people such as the religion they practise, their sexual orientation, their cultural and societal backgrounds, their politics, their physical characteristics, and their individual practises.

This covers a lot of territory as you can imagine, but is it really necessary to classify people into these groups? Well it's not necessary per say, but humans as a species are for the most part classifiers it is one of the ways we make sense of things, and we've been doing it for a few hundred thousand years or so, so the chances of us being able to break the habit is pretty slim. I say a few hundred thousand because anatomically modern humans first appeared around two hundred thousand years ago. Before this there were other species of primates such as Australopithecus afarensis (Lucy and her kin) which go back around three million years, and primates themselves go back around sixty-five million years. Now we have no way of knowing whether our predecessors classified things and likely we'll never know, but the chances are pretty good they did even if in only very rudimentary ways. In any case we as modern humans (Homo sapiens sapiens in case your interested) do classify things, and this tends to create problems (some intentional, and some not) in this little old world of ours.

Now why we classify things is a topic worthy of a lot of study and it has been studied for quite a while, but this blog is not a do it yourself degree in sociology, or psychology, so we'll leave it at that.

As the header for this blog states I'm going to be talking about critical thinking, and classification is one component of this subject. When we think critically we are forced to divide things into the plausible, and the not plausible (to put it very broadly, as there are typically varying degrees of plausibility). But before this is taken the wrong way I must point out that when someone thinks critically this does not mean that they simply take a firm unwavering stance on something, and let the dice fall where they may. This is what differentiates critical thinking from skepticism. Critical thinkers are by nature skeptical, but skeptics in many cases are not critical thinkers as they have already decided what the answer is.

Now there is nothing wrong with being a skeptic, but if you are then you have to be prepared to defend your ideas, as many people will automatically consider you to be against any idea that is somewhat controversial - in other words you become one of those dreaded "debunkers". And once you've been classified as a debunker, then it'll stick with you and will automatically be transferred to pretty much any topic that is even the slightest bit off centre.

It is much better to publicly classify yourself as a critical thinker (at least in my opinion), as in this way you don't automatically have a prejudgement against you. And you can reinforce your case by saying you are willing to entertain the notion that certain phenomena are possible, and then investigate what really is the story.

An example seems to be in order here.

Let's say you encounter a person who says they believe their house is haunted, because they hear footsteps at night.

Now a hardened skeptic would likely dismiss this as total nonsense, and thereby cause the person to not only consider them as being a rude git, but also likely cause the person with the belief to be embarrassed. If this is done enough times then I would assume it could lead to further distress on their part.

But if we look at this same scenario from the point of view of a critical thinker then we get a totally different outcome. The critical thinker who is told about the belief that there is a ghost would take the person at face value rather than making an automatic judgement and try and find out why they believe this. Ultimately this might lead to the person allowing the critical thinker to investigate the problem, and thereby determine what the noises actually are. This second solution I feel goes a long way to reassuring the person with the belief, and ultimately is much more productive as it no only confronts their fears, but it also instructs the person. Additionally it's unlikely they'll think the critical thinker is some rude git either.

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 ...
