Chris McManus considers evidence from anthropology, particle physics, the history of medicine, and the notebooks of Leonardo to answer questions like: Why are most people right-handed? Are left-handed people cognitively different from right-handers? Why is the heart almost always on the left side of the body? Why does European writing go from left to right, while Arabic and Hebrew go from right to left? Why do tornadoes spin counter-clockwise in the northern hemisphere and clockwise in the southern hemisphere? And how do we know that Jack the Ripper was left-handed? McManus reminds readers that distinctions between right and left have been profoundly meaningful--imbued with moral and religious meaning--in societies throughout history, and suggests that our preoccupation with laterality may originate in our asymmetric bodies, which emerged from 550 million years of asymmetric vertebrate evolution, and may even be linked to the asymmetric structure of matter. With speculations embedded in science, Right Hand, Left Hand offers entertainment and new insight to scientists and general readers alike. (20020915)...

    Tackle down many myths about left-handedness and right-handedness.The following is my Indonesian review for the book, first posted in another site:Bapak McManus ini adalah seorang profesor psikologi yang terobsesi pada kanan dan kiri. Penelitiannya tentang konsep kanan dan kiri pun meluas, tidak hanya dalam bidang psikologi, tapi juga neurologi, biologi, sejarah, antropologi, dan banyak lagi. Tidak salah kalau buku ini digolongkan ke dalam 'tour de force'.Beberapa hal yang dijabarkan dalam buku ini yang mungkin membuat Anda terkejut, atau mungkin melegakan Anda karena mengkonfirmasi apa yang Anda yakini selama ini:- Kenapa ada bangsa yang menulis dari kiri dan ada yang dari kanan?- Apa betul ada bangsa yang kidal semua?- Apa betul dunia ini dipadati oleh simetri? (Jawabannya: TIDAK. Tubuh manusia pun tidak simetris. Jantung ada ke kiri-tengah, hati ke kanan. Tangan, kaki, dan wajah kita juga sebetulnya tidak simetris. Molekul-molekul juga tidak simetris!)- Betul tidak sih kalau manusia selama ini baru menggunakan sepuluh persen kapasitas otaknya? (Jawabannya: SALAH.)- Mengapa banyak bangsa yang mengasosiasikan kanan dengan baik dan kiri dengan buruk/jahat?- Betul tidak orang kidal lebih berbakat seni dan cerdas daripada orang yang tidak kidal? (Jawabannya: SALAH. Seringkali ini hanya propaganda orang kidal. Beberapa tokoh terkenal - Einstein misalnya - yang diklaim kidal, ternyata tidak kidal. Lucunya, tokoh kejam atau jahat yang jelas-jelas terbukti kidal, justru biasanya tidak disebutkan oleh para 'aktivis kidal' ini. Dan ada studi yang justru menunjukkan kalau orang-orang non-kidal justru lebih tinggi kecerdasannya dibandingkan orang-orang kidal... meski hanya sedikit.)- Apa betul otak pria yang bekerja cuma yang sebelah kiri sementara yang perempuan dua-duanya? (Ini pernah disebutkan oleh sebuah majalah perempuan di Indonesia. Jawabannya, SALAH. Lembaga-lembaga pendidikan juga banyak yang mengklaim bisa mengembangkan kemampuan satu belahan otak anak [biasanya yang kanan, karena belahan otak yang ini dianggap sumber kreativitas]. Kedua belahan otak bagaimanapun hanya SEBELAH, dan baru berfungsi sebagai otak jika keduanya berfungsi dan saling terhubung.)- Kita sering dijejali informasi bahwa otak kanan itu berperan dalam kemampuan berbahasa, seni, dll, sementara yang kiri lebih matematis, logis, dll. Apa itu benar?(TIDAK SELALU BENAR. Bagi sebagian orang, letak pusat-pusat itu dalam otak terbalik. Selain itu, bahasa misalnya, juga bukan melulu porsi otak kanan. Logika bahasa ada di otak kiri. Sebagian orang yang mengalami kerusakan otak kiri, kehilangan logika berbahasanya. Ia sering tak dapat memikirkan hubungan yang benar antara satu kalimat dengan kalimat lainnya. Sebaliknya, orang yang mengalami kerusakan otak kanan, kehilangan rasa humoris akibat sulit memahami kalimat-kalimat yang lucu!)- Kenapa di Indonesia dan Inggris setir mobil ada di kanan, tapi di Amerika di kiri?- Kenapa arah jarum jam begitu, bukan sebaliknya?Masih banyak lagi hal menarik yang dibahas dengan gaya lugas oleh McManus dalam bukunya ini. Sungguh tidak rugi saya membeli dan membaca buku yang cukup tebal ini, karena begitu banyak informasi dan pengetahuan baru yang saya dapat darinya.

    I got to this book via Iain McGilchrist's "The Master and the Emissary" and came to it with high expectations... which were disappointed to the extent that I didn't complete it.Laterality is a deep and complex subject which, McManus's book's sub-title tells us, plays out at molecular, an anatomical and a cultural level. Paragraph-by-paragraph McManus's book is very stimulating. But he made it much too hard for this reader to follow the overall flow of the argument both within and across chapters. His chatty writing style, while likeable, does not help. There's no need for complex material to be serious in tone but where there's complexity I would prefer clarity over informality any day.If you are professionally interested in laterality then perhaps you will get past or not even notice the flaws I found. If, like me, you are an interested amateur then I would approach "Right Hand, Left Hand" with at least one of the following: trepidation; a pencil and notebook to scribble together the flow of the argument as you go; or a holiday where you can get through the whole thing quickly enough not to lose the thread from one chapter to the next.It's a great shame as the author very clearly both knows his stuff and is deeply excited and inspired by it. But poor editing is poor editing.

    This is a very difficult book to define, alternating between trivia and deep science, but always with a clear objective, to elucidate why we are asymmetrical, and just how asymmetrical we are.It is my first contact with McManus prose but he manages to transmit his obvious love for the subject while avoiding the excess of boredom. It also has the right balance of scientific fact and speculation to keep you interested.A surprising broad and academic book that covers neurology, chemistry, physics and embriology. among other disciplines. And amusing, many times. A must for left handed people, but also very educative for right handed, specially the mythbusting sections.

    This book is packed with information on the biological, medical, physical and socio-cultural aspects of symmetry, asymmetry, and chirality, and stories told with erudition and wit. It is unique in its kind. Probably because there is no other book that contains similar material, the author sometimes gives in to the temptation to overload his reader with every bit of information he can find on a particular aspect; at times, it is just too much, even for a chirality-afficionado like me. Still, a very valuable resource.

    As a right handed person myself, I seldom recognize how difficult for those left handed to perform a simple task in the world of right handedness. The Universe has a Logic that things should be diverted to be right handedness but except a few examples on Polyssacharides and a few DNA. The former should be right handed and the latter should be also right handedbut the crtical life sustaining protein should be left handed. People have had already a reason to sustain a life in the owlrd of right handedness witht he priority that this universe might have a mirroring counterpart which might be left handedness in all things. Parity is a must whcih has been found in Quantum Physics that a compensation in the field of parity must have been an essentialism to divert what should be left handed and what shoul dbe right handed.Cycling means a perfectness in the nature of Universal mean. Any atoms must have a spin number that spin is existed in the universal mean on the natural logic as a kind of cycling perfectness to comply with On the evolutionary sense, protein that is life sustaining should be forever meant to be left handed as nayure has chosen left handedness on the protein to perform its tasks witht he identity of left handedness key. Those found on the comets are also some life sustaining version of protein that are left handed and these are chosen to carry on the life code on Earth for over 8 millions years since the first mammal was crawling from the pcean to become terrestrial organism. Human, hominids were splitted from then on. The Brain is a critical region for recognizing left or right but ususally Nature has chosen the left brain to rule the worldiness which is totally right handed world in the manifestation. Spoken words are manipulated by the left brain as language region is located at the left hemishere of the brain and the world are all right handedness which is under the control of left brain. In fact, evolutionary process has long been stuffed witht he codes of life as a kind of righ handedness owrld and the universal logic is also spoken in a right worldiness way.Upon Quantum Physics, atoms should have a spin but according to their subatomic worldliness, they are dividied into left spin and right spin. Parity has to be dicussed here that dimensional entities should be included in the field of Quantum Physics that dimensional enitites shoul dalso have a kind of mirroring counterparts. But the cosmology of the Universe always chooses Right handedness to manipulate this worldliness and right handedness is regarded as vitality to be essebtial factor to proliferate life forms. Indeed, we can say for a few words about possibility but the ubniverse is based on the foundation od right handedness to be started for anything to proliferate into possibility. The Cosmological Logic must have chosen a certain handedness to rule the worldliness and those other possibilities are just by-product to sustain the importanc eof the main character of the right handedness worldliness only. It can say that in a spoken sentence: there is a possible world of left handedness with everything in reverse abd the sentence spoken is possible that tyhe words consistng the sentence is legal that there might be a possible world like that. Then layers by layers, how many possible worlds are there to be legal and surviving? The main factor to determine the surviving or not surviving is only the ascribed foundation on the right handedness to manifest the worldliess. Upon Quantum Physics, there is a problem on three pairs of vectors which consummate the worldliness The superficial 2D is critical for diverting whether a possibility should be left or right. Our logic is always prenatally right handedness that our left brain rules the world to put thw orldliness into a possibility of Logic as it should have been and the the other possbilities, including right handedness worldiness, is jsut situated into the minor worldlness as a kind of mirroring entity.

    Saya bahas sedikit dulu di sini sambil pemanasan buat nulis review panjangnya di blog. Kalimat pertama dari saya: Andaikan semua buku neurologi dibikin dengan gaya seperti ini...Mungkin karena nyaris semua buku neurologi yang pernah saya baca itu bikin ngantuk dan tidak enak disimak, dan buku ini menawarkan gaya penulisan yang berbeda.Ini buku sains lama yang baru saya baca versi Kindle-nya 14 tahun setelah bukunya terbit pertama kali. Kalau dilihat-lihat sinopsisnya, persoalan yang diulas dalam buku ini terkesan sepele: Urusan kiri dan kanan dalam kehidupan sehari-hari. Memang sih, judulnya "Right Hand, Left Hand". Tapi kalau disimak isinya, buku ini tidak cuma membicarakan tangan. Tapi benar-benar urusan kiri dan kanan, dalam tinjauan sains tentunya. Buku dimulai dari persoalan "mengapa jantung manusia letaknya di kiri" (dan jawabannya - terus terang - bikin pusing, apalagi kalau yang membaca tidak terlalu suka dengan sains. Bisa-bisa mabok bacanya), dan kemudian... Banyak sekali yang dibahas. Sampai saya berkali-kali dibuat terkagum-kagum dengan kedalaman Prof McManus dalam mengulas semuanya sampai ke tulang-tulangnya. Bahkan, hal-hal kecil semacam detail perubahan arah lalu lintas di Timor Leste, dan cara menulis Paul McCartney yang unik, pun dibahas tuntas.Bukti lain: Pertanyaan-pertanyaan ini semua, bisa ditemukan jawabannya dalam buku ini. (Tapi jawabannya tidak saya kasih ya. Supaya tidak spoiler)Apakah kidal atau tidaknya orang ditentukan dari posisi jantungnya?Apakah sebagian besar monyet, ikan, dan binatang-binatang lainnya juga sering menggunakan tangan kanan seperti manusia?Mengapa tulisan bahasa ada yang dari kiri ke kanan dan ada yang dari kanan ke kiri?Mengapa dalam bahasa, kata "left" dan terjemahan-terjemahannya dalam berbagai bahasa, kerap diasosiasikan negatif?Mengapa ada negara yang mengatur lalu lintasnya di sebelah kiri dan ada yang di kanan?Mengapa ada manusia yang lancar menulis dengan tangan kanan tapi malah lebih lancar memakai tangan kiri ketika melempar bola?Mengapa gejala stroke orang kidal dan tidak itu beda?Apakah benar manusia itu cuma memakai 10% kapasitas otaknya di suatu waktu?Apakah benar keahlian tangan non-dominan itu bisa dilatih?Benarkah orang kidal lebih kreatif daripada yang tidak?Adakah bangsa di dunia ini yang kidal semua?Kenapa orang kidal makin lama makin banyak?Dan puncaknya, pertanyaan ini:Mengapa ada segelintir (baca: 10-13%) orang yang kidal di antara dominasi orang yang biasa menggunakan tangan kanan?Keunikan lain dari buku ini adalah warnanya yang berbeda-beda di tiap bab. Jika bab-bab awal benar-benar sains (dan buat yang tidak suka sains, bisa saja langsung tumbang di bab-bab awal ini), bab-bab pertengahan mulai lebih praktis dan "membumi", lebih banyak membicarakan fenomena yang kita lihat sehari-hari. Sementara bab-bab akhir lebih banyak mengulas trivia (dan tetek bengek yang kelihatan kurang penting tapi sebetulnya penting diketahui), sebelum akhirnya tiba di bab 14 yang kembali berwarna sains, dan ditutup bab 15 yang memuat kesimpulan dari seluruh konten sains buku ini.Buat penikmat sains, psikologi, biologi, dan sejumlah cabang ilmu pengetahuan alam lainnya; buku ini bakal menarik sekali buat dinikmati. Tapi kalau tidak suka, barangkali buku ini kurang cocok buat kalian. Saya sendiri termasuk golongan yang memang menyukai sains, jadi saya bisa kasih bintang 5 untuk delapan dolar yang luar biasa menakjubkan ini.

    Erudite, fascinating, well-organized and clear, Right Hand Left Hand is the authoritative book on left-right asymmetry. The book can sometimes seem an eclectic tour through various intellectual disciples, but the ostensible topics of each chapter (biology, cultural anthropology, chemistry, fundamental physics, etc) are just the backdrop for the investigation of a deeper mystery. What is this deeper mystery? Well, it's spelled out in the subtitle: "The ORIGINS of Asymmetry." McManus doesn't highlight this as forcefully as he ought to, but one might say the fundamental axiom of the book is a dictum attributed to the physicist Pierre Curie: all asymmetric results must have asymmetric origins. Put another way, you can't build an asymmetric object from asymmetric subunits. But what is the definition of asymmetry? Well, an asymmetric object is non-identical to its mirror image, while a symmetric object is. However, the type of handedness of an object's subunits doesn't predict that the object will have that same handedness, but, rather, that is will have a handedness. For instance, even though the building blocks of our proteins are "left-handed", the proteins themselves are not all "left-handed"; about half are "right-handed". The books traces the asymmetry of sub-atomic particles to the asymmetry of our biological molecules to the asymmetry of our body to the asymmetry in our culture. This chain of attribution of asymmetry, from the micro to the macro, is very compelling. McManus also puts forward a theoretical genetic model of some of our boy's asymmetry, including handedness and the side of the brain that is language-dominant. I think this model is far too bold, and the rationale he provides is unconvincing. Still, spellbinding book. Read it.

    You can’t really do anything wrong with picking up any one of the Royal Society Winton Prize for Science Books winners. Right Hand, Left Hand is no exception. It may even be one of the most interesting science books, I’ve read recently — and this is not only because I am a »south paw« myself. McManus presents the whole range, from entertaining trivia to deep science, in this densely packed book. He covers the biological, chemical, physical, neurological and cultural aspects of symmetry, asymmetry, chirality, and simply handedness.

    with writing both light-hearted and dense, the book ponders asymmetry from chiral to cultural. perhaps could have used some editing to tighten up the themes a bit & make the book more accessible-- but author has a lovely voice & writes compellingly on a fascinating topic.

    A pretty long book that goes into some depth on the subjects of left-right across a wide range of subjects from chemistry to religion. A lot of it is diverting, though I found myself skimming parts of it. It's about as exhaustive as you're likely to get on the subject.

    i just started reading this one, but handedness was the topic of my very first science fair project. I proved on my three panels of cardboard that cats have a dominate "pawedness." Hoping the science in this book is a little more robust than mine...

    Great read for the month of Left-Hander's Day on the 13th. This book was amazing. It was beautifully structured and led to lots of great musing on asymmetry and symmetry.
