The History of the Nobel Prize in Medicine

 


"Attributing Excellence in Medicine: The History of the Nobel Prize" offers readers a deep dive into one of the most prestigious accolades in medical science, the Nobel Prize. But this book isn’t just a chronicle of achievements; it’s a compelling exploration of the human side of scientific greatness, a journey through the politics, personalities, and groundbreaking discoveries that have shaped modern medicine.

The authors take us behind the scenes of the Nobel Prize process, revealing not only how laureates are selected, but also the intense rivalries and philosophical debates that have defined some of the most consequential decisions in medical history. What makes this work so fascinating is its balance between historical rigor and personal storytelling. You’ll find yourself not just reading about the medical breakthroughs that saved millions of lives but understanding the often overlooked figures who were passed over for the prize—sometimes controversially so.

One of the book’s strengths is its wide scope. It traces the origins of the Nobel Prize, contextualizing Alfred Nobel’s vision of rewarding those who "conferred the greatest benefit to mankind," and follows the evolution of the prize through times of war, political upheaval, and rapid scientific advancement. The book addresses how the Nobel Prize has adapted (and sometimes struggled) to keep pace with new medical paradigms, such as the rise of genetics, biotechnology, and global health initiatives.
The authors also delve into the personal stories of laureates, shedding light on their perseverance, moments of serendipity, and even their human flaws. The narrative brings to life figures like Marie Curie, Alexander Fleming, and many lesser-known but equally pivotal contributors to medical science. Their struggles to advance knowledge in the face of adversity are inspiring, and the authors have a knack for drawing out the emotional resonance of their stories.

Yet, this book isn’t just about heroes. The authors don’t shy away from addressing the controversies surrounding the Nobel Prize, particularly the debates over who deserved recognition and who was unjustly overlooked. The inclusion of behind-the-scenes accounts of committee deliberations adds depth, illustrating the often subjective nature of deciding who gets to stand in the spotlight.

For anyone interested in the intersection of medicine, history, and human ambition, "Attributing Excellence in Medicine" is a fascinating read. It not only captures the grandeur of scientific achievement but also reflects on the complexities of recognizing and rewarding it. The result is a book that inspires both admiration for the laureates and a critical awareness of the Nobel Prize's legacy in shaping modern medicine.

This is an Open Access book.

Science History: the Babylonians and Egyptians


Sumerian god Enki, with characteristic symbols: bird, goat and water flows

The early Sumerians and Babylonians have contributed to later generations important units for the measurement of time and of angles. Babylonian in origin is the week of seven days, also the division of the day and of the night into twelve hours each. The Babylonians made quite extensive use of the sexagesimal scale in writing integral numbers and fractions; using the same scale, they divided the hour into 60 minutes and the minute into 60 seconds. The circle was subdivided into 360 degrees, the degree into 60 minutes of are, and the minute into 60 seconds. The most humble worker of the present day measures the time of work by the hour, as did the Babylonians of perhaps 5000 years ago. The most noted engineer and the most distinguished astronomer of the present time measure angles in degrees, minutes and seconds, much as did the astronomers at the Euphrates and Tigris eons ago. Early Babylonian astronomical records indicate a surprising precision. An achievement of the first magnitude was the discovery of that slow motion of the equinoctial points on the ecliptic called the precession of the equinoxes. This was done by the Babylonian astronomer Cidenas, who directed an astronomical school at Sippra, on the Euphrates, about 343 B.C.

Primitive sun-dials and water-clocks served for measuring time. For finding the angular altitude of the sun (at noon time), they used the gnomon which consisted essentially of a vertical rod of known length. The length and direction of its solar shadow afforded the necessary data. The beam-balance served for weighing medicine and precious articles. The medical recipes described in the Egyptian papyrus Ebers indicate the use of weights as small as 0.71 grams.

A Very Short History of Astronomy


2,500 BC
- Stonehenge, one of the most famous sites in the world today, once served as a burial ground. Archaeoastronomers claim that Stonehenge represents an ancient observatory, and that the site had astrological and spiritual significance as well.

650 BC - Babylonian Venus tablet of Ammisaduqa is the oldest significant astronomical text that we possess. This document, recorded on cuneiform tablets, lists the first and last visible risings of Venus over a period of 21 years.

A Very Short History of Mathematics


70,000 BC
there are drawings that indicate some knowledge of elementary mathematics and of time measurement based on the stars. Paleontologists have discovered ochre rocks adorned with scratched geometric patterns.

20,000 BC - The Ishango bone, found in northeastern Congo, is the earliest known demonstration of sequences of prime numbers and of Ancient Egyptian multiplication.

3,000 BC - The Indus Valley Civilization of North India and Pakistan developed a system of measures that used the decimal system, and an advanced brick technology which utilized ratios.

2,500 BC - The Sumerians wrote multiplication tables on clay tablets and dealt with division problems. The traces of the Babylonian numerals also date back to this period.

1,650 BC - The Rhind papyrus, a major Egyptian mathematical text, is an instruction manual in arithmetic and geometry. It gives area formulas, multiplication methods, working with unit fractions, composite and prime numbers, arithmetic, geometric and harmonic means.

550 BC - Pythagoras of Samos is credited with the first proof of the Pythagorean theorem, though the statement of the theorem has a long history. He expressed the theorem algebraically rather than geometrically.

400 BC - Jaina mathematicians from ancient India began studying mathematics for the sole purpose of mathematics. They developed transfinite numbers, logarithms, fundamental laws of indices, cubic equations, quartic equations, set theory, sequences and progressions, permutations and combinations, etc.

370 BC - Eudoxus developed the method of exhaustion, a precursor of modern integration. The Pythagoreans proved the existence of irrational numbers.

300 BC - Euclid wrote Elements, the most important mathematics book ever written. It is the first example of the format still used in mathematics today: definition, axiom, theorem, proof.

230 BC - Archimedes of Syracuse used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave remarkably accurate approximations of Pi.

400 - The Surya Siddhanta, classical Indian mathematician, introduced the trigonometric functions of sine, cosine, and inverse sine, and laid down rules to determine the true motions of the luminaries, which conforms to their actual positions in the sky.

650 - Brahmagupta lucidly explained the use of zero as both a placeholder and decimal digit, and explained the Hindu-Arabic numeral system.

825 - Muhammad ibn Musa al-Kwarizmi wrote several books on the Hindu-Arabic numerals and on methods for solving equations. The word algorithm is derived from the Latinization of his name.

1000 - Al-Karaji, a Persian mathematician, gives the first known proof by mathematical induction. He proved the binomial theorem, Pascal's triangle, and the sum of integral cubes.

1170 - Bhaskara, another Indian mathematician first conceived differential calculus, the concept of the derivative, differential coefficient and differentiation. He also stated Rolle's theorem and investigated the derivative of the sine function.

1202 - Fibonacci produced the first significant mathematics in Europe since the time of Eratosthenes, a gap of more than a thousand years. His book introduced Hindu-Arabic numerals to Europe, and discussed many other mathematical problems.

1654 - Blaise Pascal and Pierre de Fermat set the groundwork for the investigations of probability theory and the corresponding rules of combinatorics in their discussions over a game of gambling.

1665 - Isaac Newton brought together the concepts now known as calculus. Independently, Gottfried Wilhelm Leibniz developed calculus and much of the calculus notation still in use today.

1736 - Leonhard Euler, the most influential mathematician of the 18th century, solved the Koenigsberg bridge problem. He founded the study of graph theory named the square root of -1 with the symbol i, made contributions to the study of topology, etc.

1807 - Joseph Fourier announced his discoveries about the trigonometric decomposition of functions, but the demonstration was not altogether satisfactory. The final solution of the problem was given in 1829 by Jacques Charles François Sturm.

1822 - Augustin Louis Cauchy proved the Cauchy integral theorem for integration around the boundary of a rectangle. He started the project of formulating and proving the theorems of infinitesimal calculus in a rigorous manner and was thus a pioneer of analysis.

1829 - Nikolai Ivanovich Lobachevsky publishes his work on hyperbolic non-Euclidean geometry, where uniqueness of parallels no longer holds.

1832 - Evariste Galois presents a general condition for the solvability of algebraic equations. Galois and Niels Henrik Abel proved that there is no general algebraic method for solving polynomial equations of degree greater than four.

1843 - William Rowan Hamilton in Ireland discovers the calculus of quaternions and deduces that they are non-commutative.

1847 - George Boole devised Boolean algebra, in which the only numbers were 0 and 1 and in which, famously, 1 + 1 = 1. Boolean algebra is the starting point of mathematical logic and has important applications in computer science.

1854 - Bernhard Riemann introduces Riemannian geometry, which unifies and vastly generalizes the three types of geometry, and he defined the concept of a manifold, which generalize the ideas of curves and surfaces.

1899 - David Hilbert presents a set of self-consistent geometric axioms in Foundations of Geometry. In 1900, he set out a list of 23 unsolved problems in mathematics. These problems formed a central focus for much of 20th century mathematics.

1928 - John von Neumann, a Hungarian American mathematician who made major contributions to a vast range of fields, begins devising the principles of game theory and proves the minimax theorem.
