    Great science writers infect you with their curiosity and enthusiasm for their subject Bob Berman does this in a book that is informative and funny as he conveys knowledge about his awe inspiring subject our Sun While never stenting on supplying the astounding facts and figures he takes time to talk about man's relationship with our star today and throughout history There is a total eclipse coming in August 2017 across most of the USA After reading this book there's no way I will miss it

    FIRST HERE ARE MY INITIAL THOUGHTS WRITTEN AT THE HALFWAY POINT ON 23 JAN HAVE NOW FINISHED SO SCROLL DOWN FOR THE EXCITING CONCLUSIONFirst tried reading this back around 2009 but my little brain overloaded about a uarter in Still what I did understand was fascinating and so I promised to give it another try some day when I was hopefully smarterWell that day is today and I made it halfway through this time before my brain kerploded So yay me but back to my to get back to list for Mr Berman at least until I've ice packed my cerebellum with some stupid fictionMy own limitations aside Berman is an excellent science writer with an appealing sense of humor that ranges from cleverly droll to enjoyably stupid An example of the first while discussing the progress from hunter to agriculturalist Homo erectus erected the first blazing fire 500000 years ago After burgers went from raw to medium well a truly long time elapsed before the next human milestone the bunAnd a couple examples of the second When hieroglyphics were finally deciphered in the mid 19th century Aha I see It's snake before stork except after fish the inscription revealed how central the Sun was to daily lifeFrench astronomer Guillaume Joseph Hyacinthe Jean Baptiste Le Gentil de la Galaisièrefailed to arrive in time to observe the transit thanks to an outbreak of war and probably delays caused by officials writing his name on passport applicationsSo yeah you're never than a page or so away from a welcome if generally childish break from all the hard science And believe me some of this science is hard although Berman certainly does his best to if not dumb it down at least make it almost accessible to an idiot like me Much as Dava Sobel did in her small but wonderful The Planets Berman provides an excellent if too short description of the 18th century's race against time to determine the Astronomical Unit; but unlike Sobel he also manages to explain just why the AU is so important to determining the distance of the planets and how to someday reach them Berman also does a great job introducing a number of important but generally overlooked or forgotten players always one of my favorite things with any non fiction see Alan Moorehead's The WhiteBlue Nile books or any of Peter Hopkirk's character driven Central Asian histories who had a much profound impact on our understanding of the world than most of us realize Among my favorites The early Greeks Aristarchus first to write that the Sun was the center of the solar system and that Earth revolved around it once a year while spinning on its axis and Erosthenes first to calculate the size of Earth without ever leaving Egypt However despite their brilliance both were soon displaced by the famous if consistently wrong Ptolemy and his geocentric universe which became gospel for the next 1700 years Best buds Gustav Kirchhoff and Robert Bunsen he of the high school lab burner who discovered and then developed the field of spectroscopy which I never understood before but which is now super awesome Walter and Anne Maunder whose amazing insights into how sunspot activity is linked to magnetic disturbances on Earth was attacked by the at that time totally bonkers Lord Kelvin of earlier absolute zero and transatlantic cable fame relegating them to the scientific junk pile until their work was rediscovered and promoted in the mid 1900's by Jack Eddy himself one of the 20th century's most famous and important scientists that you've also probably never heard ofAnd that's all just in the first half of the book which may explain why I need a breather now But I will definitely get back to it again sooner than I did last time since Berman at least teases at discussing how a better understanding of the Sun and it's cycles might actually save us from total climate meltdown So stay tunedFINAL REVIEWTWO WEEKS LATERAaaaand DONE Took a two week breather before tackling the final 100 pages which were eually good but by the end got WAY darker no pun intendedThe second half of the book got deeper into the science which certainly made me smarter but I miss the colorful characters introduced earlier I have already impressed my colleagues by explaining how important Vitamin D is and why they should let their kids go out and play in the sun; I also now better understand the physics vs the earlier magic behind the northern lights rainbows color eclipses etc But at the same time I am now scared to frickin' death by solar flares although at least I now correctly call them coronal mass ejections or CMEs And most depressing of all while I hinted above that Berman may offer some hope that the Sun might bail us out on climate change it turns out I was wrong and so we are in fact all doomed CLIMATE CHANGE You may wonder what this has to do with the Sun and that's just Berman's point because the answer is unfortunately not much Three Sun related factors used to affect weather patterns on Earth eccentricity obliuity and precession don't worry; there won't be a test But any effect they once had has long been superseded by anthropomorphic climate forcing almost exclusively the result of increased CO2 emissions aka greenhouse gases Anthropomorphic climate forcing man made climate change has now become the biggest player in global heating If carbon emissions go unchecked all indicators predict positive feedback loops melting polar ice creates dark water oceans that absorb heat which melts ice and permafrost which releases methane and on it goes until the world is 6°F to 10°F warmer mostly due to warmer winter lows at middle and high latitudesClimate change will then be irreversible no matter what we do Those are conditions out planet has not seen for three million years The results will be spectacular Rising sea levels will be the least of them More prominent will be weather extremes with violent unaccustomed paroxysms Most prominent will be biological blights and diseases as previously cold hating pathogens spread to tasty new organisms in the plant and animal kingdomsOr as Berman sums up just one page later we're screwedAnd remember this book was published in 2011 and so researchedwritten at least 2 3 years earlier and so things have only gotten worse since then However Berman does offer a few ideas on where one might want to move to for one's final days New England and Eastern Canada might not be bad places to ride out our looming and increasingly certain Mad Max eco tastrophySigh One statistic Berman often refers to is the atmospheric CO2 level Historically that ranged from a low of 180 ppm partsmillion during Earth's coldest periods to a high of 280 ppm but never higher until the mid 20th century At the time of Berman's writing he reported a shocking level of 338 ppm and described the long term disastrous effects that would have Well a uick Google search just informed me that in 2017 the level was already up to 405 ppm higher than at any other time in the past 800000 yearsSigh

    I like getting my mind blown and this description of how the sun works and how it affects us was just the ticket did you know rainbows aren't a real tangible thing but only exist between the eye sun and rain? If you weren't there there wouldn't be a rainbow Relatively easy to read with uirky anecdotes The author is very personal and that usually makes it entertaining though a few times it got in the way

    Fun look at our nearest star This is no textbook; Berman is a storyteller so you often get just as much information on astronomers as you do on the sun But highly informative none the less Berman definitely has a thing for sunspots solar cycles and solar weather I can't say I blame him a coronal mass ejection could strike our planet at any time wiping out electronics and anything electric especially in the northern latitudes it's connected to the position of the earth's magnetic fields Also interesting to consider how the solar cycle affects our climate Thankfully sunspots have been low over the last couple of decades so the earth is staying cooler than it otherwise wouldIn fact the discussion of the sun's impact on our planet's climate was easily the most interesting portion of the book Basically variations in three components of the geometric interplay between the earth and sun affect how much of the sun's energy our planet receives First is the shape of our orbit It is usually very circular only 35% difference between nearest 916 million miles and farthest 948 million miles spots But the orbit goes through a cycle and at times there is a 13% difference Since energy received is based on the suare of the distance this variation can have a big effectThe second factor is the tilt of the earth's axis It alternates between 221 and 245 degrees ever 42000 years making seasonal differences extreme when the tilt is greater The last factor is the wobble of the earth's spin Every 11000 years the tilt switches so that the northern hemisphere has summer in January just when the earth and sun are closest Those summers would not be pleasantThe basics of the sun are here too its life cycle its powering process its emissions etc Great stuff that we should probably all know but few do

    Books about science for the lay reader have to strike a balance between being dull but informative and being entertaining but accurate At one extreme a little dullness can be forgiven if the information is amazing; at the other a few factual errors can be forgiven if the book is a good read Bob Berman tilts towards the latter end of the spectrum He gets full marks for entertainment but his book should carry a health warning concerning some of the “facts” Since it doesn’t part of my job is to warn you not to believe everything he says; but I still recommend The Sun’s Heartbeat to anyone wanting a light hearted but for all its flaws informative look at the life and death of the star on which our lives depend Berman writes in a deceptively casual style that reads like an old friend chatting to you over the backyard fence but has undoubtedly been crafted with great care His subject matter ranges from how the Sun stays hot to the myth that tidal forces affect the timing of human births always with a strong emphasis on the human element of who discovered what and where and why I particularly liked the story of how the Sun’s activity has changed in historical times and the saga of astronomer Jack Eddy’s efforts to convince sceptical colleagues that such changes affect the climate on Earth It is just Berman’s bad luck that he nails his own colours to the mast of the suggestion that the solar uiet of recent years will continue for years or decades in a book published exactly as the Sun has woken from its slumbers with a great burst of activity There is even a possibility that the book could save lives Vitamin D is an essential for our bodies and our bodies manufacture ample amounts of Vitamin D with the help of sunlight At least they used to Thanks to a combination of a fear of ultraviolet radiation and a indoor sedentary lifestyle Vitamin D deficiency diseases are on the increase The advice from medical science now says Berman is to go out in the Sun regularly without burning and without covering up “twenty minutes of unprotected midday Sun from May to July” he says for a North American resident “or a full hour or during early March April and late August through October” will suffice and then you can slap on the sunblock Now for the promised health warning of a different kind The book is riddled with mostly minor errors that result from carelessness and could have been picked up by giving the manuscript to any competent astronomer to read For example the Sun is repeatedly described as the sole source of energy for the Earth and life on Earth ignoring the fact that whole ecosystems exist in the deep ocean where they never see the Sun fuelled by heat escaping from inside the Earth There is even a respectable body of opinion which argues that life originated there The ultimate energy source of these ecosystems is heat released by the radioactive decay of elements incorporated into our planet when it formed and nothing to do with the Sun itself The same kind of radioactive elements incidentally provide than half of the electric power used in France generated by nuclear reactors To take another example the formation of the Sun is described as occurring in a “plain vanilla” cloud of hydrogen gas when in fact the cloud contained roughly 25 per cent helium And a supernova is described as “the most intense brilliance nature ever creates” ignoring the far brighter outbursts of uasars and the phenomenal stellar explosions known as gamma ray bursters There is also although this is not strictly speaking a factual error an irritating Northern hemisphere bias in the discussion of astronomical observations as in the advice about when to go out in the Sun uoted above Anyone who has visited the Southern hemisphere will tell you things look different from that perspective Perhaps the worst scientific howler is Bergman’s claim that changes in the geometry of the Earth’s orbit cause Ice Ages because they “produce changes in the amount of solar energy that reaches the Earth” They do not at least to any significant amount – what matters is that they change the balance of heat received in different seasons Sometimes in the Northern hemisphere we have very cold winters and hot summers for millennia sometimes we have relatively mild winters and cool summers for millennia; but the total heat received over a year stays the same Curiously it is cool northern summers not harsh winters that are linked with Ice Ages; it is only when the summers are very hot that the ice over Eurasia and North America melts back The most lazy historical error comes when Bergman castigates “a pair of renegade astronomers” for making “a wheelbarrowful of money” by incorrectly predicting a major California earthuake in 1974 I was one of those astronomers although actually a journalist by then and I made precisely £204057 out of the book he is referring to which was in no way a bestseller; my late colleague Stephen Plagemann got the same Berman could have emailed me to get the number right Which is relevant because it shows the level of fact checking or not fact checking that went in to the book So why in spite of everything do I recommend The Sun’s Heartbeat? Mostly because it is fun and too many science books for all their erudition simply are not Secondly because it portrays scientists as often fallible ordinary human beings There is a place here for the occasional great genius who gets it right first time but also for tales of human error pride coming before a fall and a stubborn refusal to give in even when “everyone knows” you are barking up the wrong tree Above all the author’s enthusiasm for science shines through and if even a little of that enthusiasm rubs off on his readers I can forgive him his own ration of human error

    Fantastic Fun read uick easy to understand with a cheekiness that only Bob Berman has He speaks with passion and authority about so many pieces of the sun and how they interplay with all the facets of life here on earthShould be reuired reading for a whole new generation

  8. Charity Charity says:

    if you are at all interested in the sun and like me have no real science background to your curiousity i think you will really like this book I've said it before I love books written by science reporters and this guy can't seem to reign in his doofy sense of humor isn't that what editors are for? But back to the sun lots of great info about the history of our understanding the sun Awesome and I'm only half way through

    In The Sun’s Heartbeat Bob Berman shares with us his enthusiasm for our friendly neighborhood star by sharing factoids anecdotes and other miscellaneous information The title refers to the solar cycle with the Sun changing its magnetic polarity and sunspots For the longest time very little was known about the Sun It was only within our recent memory that we were even able to pry into the Sun’s mysteries This was especially the case with Spectroscopy and other such indirect methodsNow I think little of the Sun when it is doing its job as I suppose is the case with most people The Sun is just so ubiuitous that it is difficult to think otherwise If something were to happen to the Sun we would not know of it for approximately eight minutes and twenty seconds We didn’t even know the precise distance of the Sun to the Earth until the 1960s or so Even the story of how that was achieved was interesting Now any scientist can tell you the precise composition of the Sun right down to the fraction of a percent We know approximately how long the Sun has “lived” and how long it will continue to shine We know how the Sun came to be and that the Sun is a third generation star As far as other stars go the Sun is unremarkableSome of the information was really wild and specious Take the idea that people thought it was possible to live on the Sun and that it was inhabited by people of some other variety Where did the heat and light of the Sun come from? Well from the clouds on the Sun of course There is a ton of other interesting stuff in this book along with the science that lies behind itSo this book was fantastic I really enjoyed learning a lot of things that I didn’t really know before I knew about Mass Spectroscopy but I didn’t know exactly how they figured out how long an Astronomical Unit was This book talked about all of that and with Berman’s enthusiasm being infectious

    Wow A truly amazing book This book about our sun the source of all life on our planet is not just for science fans like me but contains practical useful information for the average reader The Sun Will Save Your Life chapter is so useful and informative not to say fascinating that it was the highlight of a book that has a lot of stellar high points The author also focuses on solar eclipses and with the upcoming total solar eclipse over the US on August 21 2017 this information is right on cue I love this book The main giver of life on this planet deserves a couple of hours of study and worship from every American So read this cool book
