The extinct survivor | Price: $3,174 (£2,500) | Auction Link |  Though now extinct, the Trilobite was one of Planet Earth's great survivors, first appearing in the fossil record 520 million years ago before finally falling prey to the Permian extinction after nearly 300 million successful years. Trilobites were so common and diverse that they are often used by geologists and paleontologists to date the rock formations in which they are found. This 11-inch fossil specimen of Acadoparadoxides briareus was found in Morocco and dates from the mid-Cambrian (509-497 million years ago) period, measuring 15 x 24 x 2 ½ inches (38 x 61 x 6.5cm).

Tyrannosaurus-Rex Tooth | Price: $17,457 (£13,750) | Auction Link | The aptly named Tyrannosaurus rex (the name means "tyrant lizard king") is the most iconic of dinosaurs, with a reputation considerably enhanced by a starring role in Michael Crichton's best-selling 1990 novel Jurassic Park, Steven Spielberg's 1993 box office blockbuster Jurassic Park, and one of the best known media franchises ever created. This 3-inch tooth from a T-rex was found in Montana's Hell Creek Formation, and such is the power of media and the immutable laws of supply and demand, it fetched more at auction than even the most generous tooth fairy might have considered.

'The foundations of digital computing' by Alan Turing | Price: $37,995 (£30,000) | Auction Link | The 2014 feature film The Imitation Game brought British mathematician Alan Turing into the public consciousness in relation to his work on encryption, but his contribution to computing in general is far greater. His paper 'On computable numbers, with an application to the Entscheidungsproblem' was published in three parts in the 'Proceedings of the London Mathematical Society', introducing the concept of a 'universal machine' for the first time. Sometimes referred to as the 'Turing machine', this rare set of the three relevant copies of Turing's paper, represents a landmark in the history of computing.

'On the role of intellectuals in promoting peace' by Albert Einstein | Price: $9,499 (GBP £7,500) | Auction Link | In German, four lines on a half-leaf, 98 x 135mm, extracted from an autograph album (pen and pencil annotations, the former in French, indicating date and place). 'Die Gelehrten hätten als Avan-Garde des Friedens Wertvolles leisten können, als Landsturm wird man sie kaum mehr brauchen'. An aphorism on the missed opportunity for the scholarly community in actively promoting peace, not merely in passively defending it: 'As the vanguard of peace, intellectuals could have achieved something valuable; as its home guard, they will hardly be of use to anyone'.

'On the history and future of particle physics' by Werner Heisenberg | Price: $28,496 (£22,500)| Auction Link | German theoretical physicist Werner Heisenberg was one of the key pioneers of quantum mechanics. He is best known for the Heisenberg uncertainty principle, which he published in 1927 and was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics". This autograph manuscript is entitled 'Entwicklung der Theorie des Elementarteilchen' (Development of the theory of the particle), and is a draft of a lecture given at Eotvos Lorand University in Budapest on March 5, 1964.

'On finite and infinite dimensions' by Stephen Hawking | Price: $31,663 (£25,000) | Auction Link | Stephen Hawking first met the American physicist Charles W. Misner during the latter's 1966-67 visit to Cambridge at the invitation of Hawking's postgraduate supervisor Dennis Sciama; the two became close, and Hawking visited Misner at his own institution, the University of Maryland, at the end of 1967. Hawking's work on singularity theorems, which he first published in his 1965 doctoral thesis, overlapped with the research Misner was undertaking on geodesical incompleteness, a notion at the centre of the concepts Hawking was developing with Roger Penrose (the 'Penrose–Hawking singularity theorems'). Here, Hawking seemingly refers to a proof that another of their colleagues in the field, Stanley Deser, would publish the following year in the Physical Review Letters, in a paper entitled 'Positive-Definiteness of Gravitational Field Energy'.

"The greatest work in the history of science" first English edition |  Price: $55,409 (£43,750) | Auction Link | The first edition of Isaac Newton's landmark text, Philosophiæ Naturalis Principia Mathematica was published in Latin on July 5, 1687 and when copies of that initial print run come to auction, they always appear in our annual list of the most valuable scientific documents of the year. The last full copy to reach auction sits in the top ten most valuable scientific documents of all time, fetching $3,719,500 at a Christies auction in New York in December, 2016. Newton's famous work on the laws of motion and universal gravitation is often referred to as "the greatest work in the history of science," and Newtonian physics was all we knew until roughly a century ago when Albert Einstein's theory of relativity advanced our understanding in one quantum leap. Einstein was a huge fan of Newton and once referred to Newton's theories as "perhaps the greatest intellectual stride that it has ever been granted to any man to make." The first edition of the work in English required the passing of a further 42 years, and makes a far more accessible and desirable keepsake of the scientific method IMHO. Firstly, it is far cheaper than a Latin first edition, and most importantly, you'll be able to read it and maybe even understand it.

A six-inch tooth from history's deadliest predator | Price: $5,555 (£4,375) | Auction Link | The Megalodon (Carcharocles megalodon) is an extinct species of shark that lived from 23 to 3.6 million years ago. Its ancestry is subject to considerable debate, with current thought suggesting it diverged from the Great White Shark family during the Early Cretaceous Period. Family resemblance aside, the megalodon was unquestionably one of the largest, powerful and most fearsome predators to have ever lived, with fossil remains suggesting it grew to 18 meters (59 ft) with the average size being 10.5 meters (34 ft). Scientists have calculated that megalodon jaws could exert a bite force of up to 180,000 newtons (40,000 lbf), with teeth designed for grabbing prey and crushing bone. This megalodon tooth is six inches long, and was found in the Hawthorn Formation in South Carolina. A full Megalodon jaw went to auction a few years back at Bonhams, presented in fully open pose just as its prey would have seen as it closed in for the kill - the open jaw measured 8 feet high and 9.5 feet wide.

11-inch Elephant Bird Egg |  Price: $44,437 (£35,000) | Auction Link | As far as we know, the largest bird of all time was the now-extinct elephant bird (Aepyornis maximus). The flightless animal stood over 10 feet tall (3 m), and was native to Madagascar. Elephant birds died out as a species approximately 500 to 1,000 years ago, the prevailing theory being that humans reduced their habitat and/or over-hunted them. The Elephant Bird was thought to be the giant flying beast known as the Roc (or Ruhk) in the tales of Sinbad and accounts of Marco Polo's voyages. This complete egg is 11 inches tall, and eight inches in diameter (28 x 20 x 20cm).

A letter of condolence by Albert Einstein | Price: $28,496 (£22,500) | Auction Link | This letter to Dr Isidore Held offers a touching glimpse into the deep humanity of Albert Einstein. Held was a noted New York doctor and philanthropist who had collaborated with Einstein to assist Jewish refugees from Nazi Germany. The Helds' son, Captain Abraham Held died whilst serving with US forces in Germany on April 8, 1945, exactly a month before the end of the war in Europe.Einstein declares himself "deeply shaken by the news of the terrible blow that has so suddenly and unexpectedly broken in upon you. It is the hardest thing that older people can encounter, and it is no consolation that such countless thousands are afflicted by similar fates. I dare not try to comfort you ..."He goes on with a remarkable image of human life: "We human beings habitually live in the illusion of safety and being at home in a familiar physical and human environment. But when the path of the everyday and the expected is interrupted, we realise that we are like ship-wrecked beings who balance in the open sea on a wretched plank and have forgotten where they come from and do not know where they are drifting to. But once one has really found one's way into this realisation, one lives more easily, and there can be no further real disappointment."

Words of wisdom from Albert Einstein | Price: $15,831 (£12,500) | Auction Link |  Albert Einstein is perhaps the most universally admired individual in history. As we noted in our Top 50 Scientific documents of 2017 feature, the simplest of Einstein memorabilia often fetches a fortune at auction. That article chronicles two similar notes of wisdom to this that fetched far more, so this autograph paragraph by the great man may one day fetch similar riches. In German, it reads: 'Sei wohlwollend gegen die Menschen aber gleichgültig gegen ihr Verhalten und ihre Meinungen', which means 'Be benevolent towards people but indifferent to their conduct and opinions'.

'As curious as children before the great puzzle of existence' by Albert Einstein |  Price: $26,913 (£21,250) | Auction Link| This autograph letter from immortal scientist and humanitarian Albert Einstein to his dear friend Otto Juliusburger, is dated September 29, 1947. Written in German, to congratulate his friend on having reached his 80th birthday, it translates in part as: "I can hardly believe it's possible! ... People like us die of course as all do, but as long as they are alive, they do not grow old. I mean that they stand forever curious as children before the great puzzle in the midst of which we have been placed. This provides a distance from everything that is unsatisfactory in the human sphere – and that is quite a lot'.Einstein reflects in the letter that whatever disgust he feels in the morning at "what the New York Times serves up, it is at least better than the Nazis." The letter closes with good wishes to Juliusburger, including for the strength to complete his life's work.

Bargain basement moon rock |  Price: $12,696 (£10,000 reserve - no sale) | Auction Link | Last December (2018), a few tiny shards of moon rock fetched $855,000 at auction, which is understandable given they are the only pieces of moon rock resultant from mankind's space exploration that have fallen into private hands, and the astonishing cost of the space programmes that retrieved them. There's always a better way though, and disregarding the provenance of the rocks, there's now a much more cost efficient way of getting a slice of the moon on your desk or mantlepiece. In 1982, an expedition in Antarctica found an unusual meteorite, which was subsequently analysed by the Smithsonian and found to resemble the rocks brought back from the Moon by the Apollo program. It turns out that the meteorites which created all those craters on the moon resulted in lumps of the moon being fired into space, and some of those rocks made it all the way to Earth. Since then, more than 300 lunar meteorites have been discovered and roughly one in every thousand newly discovered meteorites is a lunar meteorite. The above lump of moon rock is a slice of a lunar meteorite found in the Sahara desert, weighs 26.2 grams, and measures 1 x 1 x 1 1/3 inches (25 x 29 x 34mm). It went to auction last week with an estimate of GBP £10,000 to £15,000 (US$12,640 to $18,960) and did not meet reserve. Provenance is a powerful multiplier on the auction block, but comparing the prices fetched for the moon rocks last December ... hey, moon rock is moon rock, isn't it?

There's always a better way though, and disregarding the provenance of the rocks, there's now a much more cost efficient way of getting a slice of the moon on your desk or mantlepiece. In 1982, an expedition in Antarctica found an unusual meteorite, which was subsequently analysed by the Smithsonian and found to resemble the rocks brought back from the Moon by the Apollo program. It turns out that the meteorites which created all those craters on the moon resulted in lumps of the moon being fired into space, and some of those rocks made it all the way to Earth. Since then, more than 300 lunar meteorites have been discovered and roughly one in every thousand newly discovered meteorites is a lunar meteorite. The above lump of moon rock is a slice of a lunar meteorite found in the Sahara desert, weighs 26.2 grams, and measures 1 x 1 x 1 1/3 inches (25 x 29 x 34mm). It went to auction last week with an estimate of GBP £10,000 to £15,000 (US$12,640 to $18,960) and did not meet reserve. Provenance is a powerful multiplier on the auction block, but comparing the prices fetched for the moon rocks last December ... hey, moon rock is moon rock, isn't it?

Christie's held two science-related auctions last week. The first was an online only sale entitled "On the Shoulders of Giants: Making the Modern World," which ran from May 16 to May 23, followed by a Science & Natural History sale held in London on May 24. Across the two, some quite remarkable scientific artifacts were on offer. From T-Rex teeth to tribolites to words of wisdom from Mr. Einstein, here's our pick of the offerings.

The foundations of digital computing

'The foundations of digital computing' by Alan Turing | Price: $37,995 (£30,000) | Auction Link | The 2014 feature film The Imitation Game brought British mathematician Alan Turing into the public consciousness in relation to his work on encryption, but his contribution to computing in general is far greater. His paper 'On computable numbers, with an application to the Entscheidungsproblem' was published in three parts in the 'Proceedings of the London Mathematical Society', introducing the concept of a 'universal machine' for the first time. Sometimes referred to as the 'Turing machine', this rare set of the three relevant copies of Turing's paper, represents a landmark in the history of computing.

Price: $623,702 (£491,250) | Auction Link

The flightless dodo bird (Raphus cucullatus) has been a symbol for extinct species in general for more than a century, thanks to being popularized by Lewis Carroll who used the Dodo as a character in Alice's Adventures in Wonderland. A native of Mauritius, the last live specimen was seen in 1662. This specimen is the only complete skeleton to have been assembled in the 19th century still in private hands. There's a more complete story and video about the Dodo on Christie's site, and though imagery of the bird is rare, a Dodo sculpture by Michele Vitaloni sold for $25,392 (£20,000) at the same sale.

"As curious as children before the great puzzle of existence" by Albert Einstein

'As curious as children before the great puzzle of existence' by Albert Einstein |  Price: $26,913 (£21,250) | Auction Link| This autograph letter from immortal scientist and humanitarian Albert Einstein to his dear friend Otto Juliusburger, is dated September 29, 1947. Written in German, to congratulate his friend on having reached his 80th birthday, it translates in part as: "I can hardly believe it's possible! ... People like us die of course as all do, but as long as they are alive, they do not grow old. I mean that they stand forever curious as children before the great puzzle in the midst of which we have been placed. This provides a distance from everything that is unsatisfactory in the human sphere – and that is quite a lot'.Einstein reflects in the letter that whatever disgust he feels in the morning at "what the New York Times serves up, it is at least better than the Nazis." The letter closes with good wishes to Juliusburger, including for the strength to complete his life's work.

'A new definition for space-time singularity' by Stephen Hawking | Price: $205,807 (£162,500) Auction Link 

Price: $205,807 (£162,500) | Auction Link

In this 1968 autograph letter by eminent scientist Stephen Hawking' to Charles W. Misner, Hawking writes: "I want to propose a new definition of what should be regarded as a physical singularity; space-time is singularity free if and only if it is geodesically bounded. By this I mean that under the exponential map every compact set in the timeline and null region of the tangent bundle maps into a set in the manifold with compact closure."

He then goes on to illustrate his meaning, "geodesically complete => geodesically bounded => distant boundaries," noting that "the arrows in the reverse direction hold if the strong causality condition holds. I can show that is there is a compact slice with converging normals and if the density is not zero at some point of the slice then space-time is not geodesically bounded."

11-inch Elephant Bird egg

11-inch Elephant Bird Egg |  Price: $44,437 (£35,000) | Auction Link | As far as we know, the largest bird of all time was the now-extinct elephant bird (Aepyornis maximus). The flightless animal stood over 10 feet tall (3 m), and was native to Madagascar. Elephant birds died out as a species approximately 500 to 1,000 years ago, the prevailing theory being that humans reduced their habitat and/or over-hunted them. The Elephant Bird was thought to be the giant flying beast known as the Roc (or Ruhk) in the tales of Sinbad and accounts of Marco Polo's voyages. This complete egg is 11 inches tall, and eight inches in diameter (28 x 20 x 20cm).

Bargain basement moon rock

"The greatest work in the history of science"

"The greatest work in the history of science" first English edition |  Price: $55,409 (£43,750) | Auction Link | The first edition of Isaac Newton's landmark text, Philosophiæ Naturalis Principia Mathematica was published in Latin on July 5, 1687 and when copies of that initial print run come to auction, they always appear in our annual list of the most valuable scientific documents of the year. The last full copy to reach auction sits in the top ten most valuable scientific documents of all time, fetching $3,719,500 at a Christies auction in New York in December, 2016. Newton's famous work on the laws of motion and universal gravitation is often referred to as "the greatest work in the history of science," and Newtonian physics was all we knew until roughly a century ago when Albert Einstein's theory of relativity advanced our understanding in one quantum leap. Einstein was a huge fan of Newton and once referred to Newton's theories as "perhaps the greatest intellectual stride that it has ever been granted to any man to make." The first edition of the work in English required the passing of a further 42 years, and makes a far more accessible and desirable keepsake of the scientific method IMHO. Firstly, it is far cheaper than a Latin first edition, and most importantly, you'll be able to read it and maybe even understand it.

A six-inch tooth from history's deadliest predator

A six-inch tooth from history's deadliest predator | Price: $5,555 (£4,375) | Auction Link | The Megalodon (Carcharocles megalodon) is an extinct species of shark that lived from 23 to 3.6 million years ago. Its ancestry is subject to considerable debate, with current thought suggesting it diverged from the Great White Shark family during the Early Cretaceous Period. Family resemblance aside, the megalodon was unquestionably one of the largest, powerful and most fearsome predators to have ever lived, with fossil remains suggesting it grew to 18 meters (59 ft) with the average size being 10.5 meters (34 ft). Scientists have calculated that megalodon jaws could exert a bite force of up to 180,000 newtons (40,000 lbf), with teeth designed for grabbing prey and crushing bone. This megalodon tooth is six inches long, and was found in the Hawthorn Formation in South Carolina. A full Megalodon jaw went to auction a few years back at Bonhams, presented in fully open pose just as its prey would have seen as it closed in for the kill - the open jaw measured 8 feet high and 9.5 feet wide.

"On finite and infinite dimensions" by Stephen Hawking

'On finite and infinite dimensions' by Stephen Hawking | Price: $31,663 (£25,000) | Auction Link | Stephen Hawking first met the American physicist Charles W. Misner during the latter's 1966-67 visit to Cambridge at the invitation of Hawking's postgraduate supervisor Dennis Sciama; the two became close, and Hawking visited Misner at his own institution, the University of Maryland, at the end of 1967. Hawking's work on singularity theorems, which he first published in his 1965 doctoral thesis, overlapped with the research Misner was undertaking on geodesical incompleteness, a notion at the centre of the concepts Hawking was developing with Roger Penrose (the 'Penrose–Hawking singularity theorems'). Here, Hawking seemingly refers to a proof that another of their colleagues in the field, Stanley Deser, would publish the following year in the Physical Review Letters, in a paper entitled 'Positive-Definiteness of Gravitational Field Energy'.

Stephen Hawking first met the American physicist Charles W. Misner during the latter's 1966-67 visit to Cambridge. The two became close, and Hawking visited Misner at his own institution, the University of Maryland, at the end of 1967. Hawking's work on singularity theorems, which he first published in his 1965 doctoral thesis, overlapped with the research Misner was undertaking on geodesical incompleteness, a notion at the centre of the concepts Hawking was developing with Roger Penrose.

A letter of condolence by Albert Einstein

A letter of condolence by Albert Einstein | Price: $28,496 (£22,500) | Auction Link | This letter to Dr Isidore Held offers a touching glimpse into the deep humanity of Albert Einstein.

The Helds' son, Captain Abraham Held died whilst serving with US forces in Germany on April 8, 1945, exactly a month before the end of the war in Europe.Einstein declares himself "deeply shaken by the news of the terrible blow that has so suddenly and unexpectedly broken in upon you. It is the hardest thing that older people can encounter, and it is no consolation that such countless thousands are afflicted by similar fates. I dare not try to comfort you ..."He goes on with a remarkable image of human life: "We human beings habitually live in the illusion of safety and being at home in a familiar physical and human environment. But when the path of the everyday and the expected is interrupted, we realise that we are like ship-wrecked beings who balance in the open sea on a wretched plank and have forgotten where they come from and do not know where they are drifting to. But once one has really found one's way into this realisation, one lives more easily, and there can be no further real disappointment."
