Images, récits et faits sur l'élément oxygène dans le tableau périodique | solides de Platon spirituel

oxygène À -183,0 ° C, l'oxygène est un beau liquide bleu clair, mais à la température ambiante, il y a un gaz incolore. Il ne s'agit que de 21% de l'atmosphère – les 21% dont nous avons tous besoin si nous voulons vivre plus que quelques minutes de plus.

Faites défiler la liste pour voir des exemples d'oxygène.

Plus grand | Spin | 3D Tige à oxygène portable.
Les bâtonnets d'oxygène étaient un bâton pendant un certain temps, je pense que c'est un peu fini, mais vous pouvez toujours acheter des bidons d'oxygène concentré (ils disent qu'ils sont d'environ 80%, contre 21% de concentration naturelle dans l'air) destinés à être inhalés pour des raisons non médicales. raisons.
Dans une barre d'oxygène appropriée, asseyez-vous avec un tube dans le nez et essayez de paraître cool et de prétendre que vous n'avez pas de tube dans le nez. Dans cette version portable, vous êtes censé inspirer profondément tout en faisant rebondir l'air (excuser l'oxygène) sur votre visage.
L’air respiratoire enrichi en oxygène est un traitement réel dans les cas où une maladie (par exemple, le tabagisme induit par le cancer du poumon) empêche l’absorption d’oxygène suffisant ou des conditions (par exemple, une réduction du flux sanguin périphérique) rend souhaitable d’augmenter la quantité d’oxygène dans le sang au-dessus de son niveau normal.
S'il y a un avantage à respirer plus d'oxygène si vous ne présentez aucune de ces conditions, c'est moins clair.

Bol à oxygène avec oxygène liquide

plus Bol d'oxygène liquide.
L'oxygène liquide est bleu, beau bleu ciel (bien que le bleu du ciel n'ait rien à voir avec le fait que l'oxygène sous forme liquide est bleu). Mais ce n'est pas vraiment tout à fait cette bleu, sauf dans certaines conditions. OK, je me sens coupable, je l’avoue: le bleu de cette image s’est légèrement amélioré. Mais il semble très bleu, même bleu, lorsque vous le voyez par exemple sous un ciel bleu à la lumière directe du soleil ou sous certains types de lumière, comme les halogénures métalliques de mon magasin. Je voulais capturer l'incroyable bleu de mon article de tableau périodique, et j'avoue que je l'ai aidé un peu dans Photoshop. C'est une chose honteuse à faire et je suis désolé. (Au cas où vous vous le demanderiez, les seuls autres échantillons de mon affiche dont l'ajustement des couleurs avait été appliqué à l'or et au cuivre, qui, pour une raison quelconque, ne sont pas simplement dorés ou cuivrés dans une impression, bien que les échantillons soient très bien personnels. Dans les cas, comme dans le cas de l’oxygène, j’essayais de faire en sorte que les photos ressemblent aux échantillons, même si cela impliquait d’ajuster les couleurs en fonction de la stricte application de la balance des blancs mesurée. et parfois vous devez vous plier aux règles pour éliminer les mensonges dans lesquels la caméra entre.)

Cet exemple représente l’élément poste de tableau périodique photographique. La copie contient le texte exactement tel qu'il apparaît sur l'affiche. Il vous est conseillé de vous en procurer une copie.

Tube d'arche monté à l'oxygène

Plus grand | Spin | 3D Tuyau d'arche monté.
À certains égards, les gaz sont pénibles du point de vue des essais. À l'exception du chlore et du brome, ils se ressemblent tous: rien du tout. Mon bel ensemble de bouteilles de gaz noble est magnifique à cause des flacons, pas de ce qu’ils contiennent, qui ne diffère pas de l’air ou de l’aspirateur ordinaire. (Si bien que je les ai eues à un bon prix parce que le vendeur pensait était vide.)

Mais réglez un courant électrique dans presque tous les gaz, et les choses sont totalement différentes. Le courant ionise le gaz et lorsque les électrons retombent sur leur chemin, ils émettent de la lumière à des fréquences très spécifiques. Ces lignes spectrales sont facilement visibles avec un spectroscope de poche très bon marché et donnent aux tubes incandescents des couleurs très inhabituelles. Si inhabituel qu'ils sont fondamentalement impossibles à photographier. Les images ici ne ressemblent tout simplement pas aux vraies couleurs de ces tubes, qui ne peuvent pas être représentées par des mélanges limités de rouge, de vert et de bleu disponibles sur ordinateur ou sur des photographies imprimées.

David Franco a aidé à organiser ces tuyaux, qui ont été fabriqués par un homme spécialisé dans les tuyaux pour gaz rares et les tuyaux Geissler (cliquez sur la source). J'ai des tuyaux installés dans chacun des cinq points de gaz rares stables du tableau, fixés sous un transformateur haute tension. Ils sont vraiment très beaux. Sur ma page Noble Rack, j'ai rassemblé toutes les photos, ainsi que des images des arcs que j'ai faits dans ma deuxième collection de bouteilles de gaz précieux.

Ce tube à oxygène n’est pas installé dans la table car il est si faible que vous ne pouviez pas vraiment le voir et il n’est pas long. Je me suis donc contenté de le tourner assez longtemps pour faire les photos (y compris une rotation de 360 ​​degrés).

Je suis sûr qu'il y a du vrai oxygène ici, je ne sais pas pourquoi. Il peut être rafraîchissant de respirer de l’oxygène pur si cela ne vous donne pas la tête qui tourne, mais une bouteille aérosol légère comme celle-ci ne peut en contenir assez pour faire toute la différence. L'un d'eux contient également de l'eau qui est probablement plus responsable de l'effet rafraîchissant que l'oxygène, en particulier si la bouteille est refroidie, comme ils le suggèrent, avant de la vaporiser sur le visage.

Mini bouteille de gaz de soudage oxygène

Plus grand | Spin | 3D Mini bouteille de gaz de soudage.
De tels cylindres sont vendus dans toutes les quincailleries pour une utilisation avec de petites torches de soudage / brasage. Ils ne ressemblent pas aux lourdes bouteilles d'oxygène à paroi épaisse utilisées avec de véritables défauts de soudage. Mais ils sont bon marché et contiennent réellement de l'oxygène.

Beaucoup ne se rendent pas compte que l’acétylène n’est là que pour faire avancer les choses avec un chalumeau oxyacétylène. Lorsque l'acier est suffisamment chaud, éteignez l'acétylène et soufflez de l'oxygène propre dans le processus. L'oxydation (la combustion) du fer en oxygène pur dégage suffisamment de chaleur pour maintenir la réaction en marche, et un jet d'oxygène à haute pression peut littéralement brûler à travers une plaque d'acier solide épaisse d'un pouce.
J'ai appris cela de Harry Barnhart, un agriculteur pensant qui m'a montré comment cela s'est fait il y a de nombreuses années.
Parce que l'air qui nous entoure n'est constitué que d'environ 21% d'oxygène, l'acier brûlera dans l'air, mais ne générera pas suffisamment de chaleur pour continuer à brûler dans un sens. Dans les airs, l'acier refroidira et cessera de brûler assez rapidement à moins que vous ne lui donniez plus de chaleur. C'est le principe de la lampe de coupage à l'arc au plasma (image sous hafnium), qui utilise uniquement de l'énergie et de l'air pour couper l'acier. Comme lorsque vous éteignez l'acétylène dans une torche en oxyacétylène, l'acier lui-même est le carburant qui alimente la coupe, mais sans oxygène pur pour activer des choses, le couteau de découpe au plasma doit utiliser un arc pour fournir la chaleur supplémentaire requise.

Une autre chose amusante à faire avec l'oxygène sous forme liquide est de l'utiliser pour accélérer le processus de gril. La documentation classique à ce sujet était disponible ici, sauf qu'elle a été supprimée en raison des préoccupations de l'université.

Oxygène Coltan

Plus grand | Spin | 3D Minerai de coltan.
Vous avez peut-être entendu parler d'une tentative, il y a quelques années, d'organiser un boycott des téléphones portables. C'est la motivation derrière le boycott: Coltan. Le nom est une contraction de la columbite et du tantale, qui sont les minéraux les plus importants présents dans le minerai. Le nom columbite vient de l'ancien nom niobium, columbium. La tantalite est bien sûr nommée d'après son composant principal, le tantale. Le coltan est un gros minerai de tantale, utilisé dans les condensateurs de presque tous les appareils électroniques numériques, y compris les téléphones portables (et les ordinateurs, les poupées parlantes et les défibrillateurs, et pratiquement tout ce qui a été inventé depuis 1980).
Le problème avec le coltan est qu’il provient en partie d’une région du Congo qui est l’un des derniers habitats pour les gorilles. C'est également la patrie de l'autre type de gorille, les guérillas, qui se combattent pour se faire prendre diverses guerres et utilisent les revenus de l'extraction de coltan pour payer les guerres. Des gorilles sont tués pour financer des guerres de guérilla, et l’électronique numérique en est le destinataire.
Le boycott ne dure pas longtemps et il est un peu difficile d’imaginer comment les sponsors ont planifié de l’organiser sans utiliser de téléphone portable. Il convient également de noter que moins d'un pour cent de l'offre mondiale de tantale provient du Congo.

Très beau et rare corail hawaïen, échangé contre une affiche et des nodules de nickel et de cuivre. Voici l'information qui l'accompagne:

Hawaiian Precious & Pink Beauty & # 39; corail

Precious coral has been for centuries prized by the people in Japan-third in value after gold and silver-because of its fine dense quality, its exquisite colors, and because it always has been associated with 'good luck,' and for several hundred years, expert craftsmen in several coral centers of Japan have been fashioning such precious coral of various shades and colors into fine pieces of jewelry-ornaments for Obi Clasps, kanzashi (ornamental hair pins), and more recently into rings, pendants, necklaces, and brooches This precious coral is completely different from black coral. Whereas black coral is merely an organic compound, precious coral is a calcium carbonate crystal commonly known as calcite, and is composed of hard skeletons of certain marine organism and grows very slowly, possibly at a rate of approximately one inch every 200 years, and in Hawaii occurs in colors from a salmon red, dark pink, pink, pale pink to snow white. 'Angel Skin' is the term commonly applied to the dark pink and medium pink shades.

The precious coral you have in your hand is a representation from only several hundred pounds of which were harvested from a depth of 1200 to 1500 feet (the length of 4 to 5 football fields) in the Molokai Channel, only a 'stones throw' from the Makapuu Lighthouse on the island of Oahu and is therefore genuinely Hawwaiin. The 'ground' which was discovered by University of Hawaii scientists in the fall of 1966 is so far the only known production area in the island chain, and several attempts to locate other grounds in the waters of the Hawaiian Islands have been unsuccessful. Precious Coral-the prefect gift and souvenir of Hawaii-from Hawaii-buff it, polish it, fashion it into jewelry of your own design, or just save it as a memento of your prefect Hawaii vacation.

Titanium dioxide is the white in white paint and the opaque in most other paints. Chances are if you look up from your screen, you'll be looking at a wall covered in titanium dioxide. It is cheap and common, unlike titanium metal, which is expensive and not seen nearly as often. This is because turning titanium dioxide (which is one of the main ores of titanium) into its metal form is difficult and expensive, as is working the metal once you have refined it.

Oxygen Superconducting powder

Larger | Spin | 3D Superconducting powder.
This is a small vial of superconducting yttrium-barium-copper-oxide powder. Normally this type of material is seen pressed into pellets that can be used to levitate magnets or perform other superconducting experiments. Background information from the source:

Yttrium barium copper oxide was discovered in the late 1980's as being the first known substance to exhibit superconductivity above 77 Kelvin (-321272F, -195C) outside of a mind-meltingly strong magnetic field. In the grand scheme of things, 77 Kelvin is a completely random value–it has no greater cosmic meaning, it's not an ultimate limit that contradicts some obscure physics theory, nothing like that. Rather, 77 Kelvin is the boiling point of nitrogen. The significance is simply that with the discovery of this material, superconductivity was a phenomenon that suddenly emerged from the realm of "laboratory curiosity" into the wide bright world of "industrially and economically feasible," using liquid nitrogen as a coolant. Previously, liquid hydrogen or liquid helium were necessary to access the temperatures at which superconductivity could be observed (outside of that frog-levitatingly strong magnetic field), both of which are at least an order of magnitude more expensive than liquid nitrogen.

The next breakthrough of the same significance would be the discovery of superconductivity at 194 Kelvin, the temperature of dry ice, which at the time of this writing, is not too far from realization (the current recordholder is 138 Kelvin, using a precise composition of Mercury Thallium Barium Calcium Copper Oxide…nice and toxic too). As a result, it is one of the most popular fields in materials and physics research today, which leads to samples such as this one.

However, the superconductive properties of YBCO depend intimately on the exact composition, which is never stoichiometric (integer values for the elemental subscripts). At the most basic level, special methods of synthesizing and altering this compound are used to add and subtract oxygens, which changes the valence state of copper so that different valence states are scattered through the material. Interestingly, the actual cause and mechanism of superconductivity is extremely complicated, and not known precisely. But researchers in a laboratory would likely take this sample, and use it in either a oxidizing or deoxidizing process to create exactly the composition they desired for whatever phenomena they were investigating.
Gentlemen, start your measurements!

Oxygen Molybdenum trioxide crystals

Larger | Spin | 3D Molybdenum trioxide crystals.
These are lovely transparent crystals of molybdenum trioxide which I made myself using nothing more than an acetylene welding torch and a molybdenum plate. Lovely. Just lovely. Too bad I was prøver to make diamonds, not molybdenum trioxide. It seems that blowing an ordinary acetylene torch at a molydenum or silicon plate held at the right temperature will cause a thin film of diamond to form slowly on the surface. After my first attempt at this I saw a few tiny flakes of what was unmistably transparent crystal material. Needless to say I was pretty excited by this. Unfortunately, when I continued the experiment I started getting lots and LOTS of this beautiful crystal material, so much that it could not possibly be diamond, since what was expected was a few microns of polycrystalline film, not macroscopic crystals like these. Sadly, it is simply molydenum trioxide, a species that forms in air at high enough temperatures.
I'm still working on the diamond making, it will be a Popular Science column if I get it to work.

Oxygen Fancy chocolate tin

Larger | Spin | 3D Fancy chocolate tin.
This chocolate tin is a sign of the beginning of the end of good chocolate. It's a tin of Hershey's dark chocolate advertised as 65% cocoa. Promoting chocolate on the basis of its percentage of cocoa is an increasingly common marketing tactic, marred only by the fact that beyond about 50% more cocoa means worse chocolate. 99% chocolate, which is actually available, is basically impossible to eat.
The force at work here is snobbery, and the need for something that tastes really bad to base the snobbery on. (Things that actually taste intelligent are of no use to snobs, because anyone can appreciate them.)
The same force is responsible for vast amounts of perfectly good grape juice being allowed to go sour and become wine. Basically, when you get right down to it, wine does not taste very good. But you can't show off how sophisticated you are by appreciating fine grape juice because pretty much everyone likes it. It tastes good. Wine, on the other hand, tastes bad, so if you go around claiming that you appreciate it at some higher level, and can in even tell the difference between minutely different varieties of it, you can appear refined and sophisticated to the naive who have not yet learned to pretend to like it.
Chocolate used to be about tasting good: In this regard milk chocolate is obviously superior. Now all sorts of people turn their nose up at milk chocolate and sniff that ils only consume fine dark chocolate. No less than 80% cocoa please. If you ask why they would want to eat that bitter crap suitable only for baking or mixing with milk to make an edible confection, they start talking about fruity aromas and what year the cocoa beans were harvested. Get the picture? They are chocolate snobs who, exactly like wine snobs, actually don't much like the stuff either, but prefer artificial superiority to genuine enjoyment.
It's a sad day when this attitude infects even Hershey's, long the bastion of low-brow but good-tasting milk chocolate. How long will it be before there are whole stored dedicated to inedible dark chocolate sorted by vintage, while those seeking the simple pleasure of good chocolate have to turn to the back isles of the grocery store, next to the grape juice?

Larger | Spin | 3D Electromagnetic Sensor.
Ah, this brings back memories. I made this thing some time in high school: It's supposed to be a general purpose "microphone" for electric or magnetic fields or vibrating metal parts. I turned the handle on a little toy wood lathe, and got a coil of fine wire from a small electric motor. Behind the coil are a couple of permanent magnets from Radio Shack. If you connect it (using the RCA jack at the base of the handle) to an audio amplifier you can actually hear things when you hold it near something that's producing oscillating fields (e.g. a speaker, electric appliance, etc). The idea behind the permanent magnets is to make it work with any vibrating metal, not just electrically-active objects, but that part never really worked as well as I'd hoped.

The 360 spin video of this is really quite nice: You can see a lot of macro photographs of insects, but how many macro-rotations have you seen lately? Other than on this website, they are few and far between. The detail is pretty amazing: This shot was taking with a 10 megapixel Canon 40D using a Canon 65mm 1X-5X super macro lens, one of the finest available for objects down to about 1/4" across. And we've got 359 more of them, each as sharp and detailed as this one, just from different angles.

The mineral chrysotile is the basis of the most widely used form of asbestos, and the safest. In fact, this form of asbestos is still in current production in many parts of the world and is considered safe by many people and organizations (though not by all). It is chemically and physically different from all the other minerals used in asbestos (see samples above and below). The others are Amphibole silicates while chrysotile is a serpentine mineral. Whether it is completely safe or not depends on the form it's in (and on who you ask), but it is generally agreed that chrysotile is the least potent carcinogen among the asbestos minerals.

Oxygen Actinolite asbestos

Larger | Spin | 3D Actinolite asbestos.

The name "asbestos" used to mean a wonder-material, an insulator without equal and a strengthening fiber so cheap and strong it was used in building materials worldwide. Today the name means nothing but death and ruin.

Asbestos had been used so widely and for so long that it must have seemed beyond credibility when evidence first started appearing that it might be harmful. It is, after all, just a natural mineral, a rock dug from the ground. It contains no toxic elements or compounds. As a silicate mineral, asbestos is a member the group of minerals that make up as much as 90% of the earth's crust. How could such a common rock possibly be dangerous?

The answer lies in its shape. As you can see from this and the other asbestos samples below, the difference between asbestos and other silicate minerals is that asbestos appears in the form of very fine hair-like fibers. This fibrous nature is what makes it so useful as an insulator and building material: It can be woven, braided, pressed into mats, or mixed with plaster or concrete to make a strong, fiber-reinforced material. (It's also fireproof and impervious to most chemicals: What more could you ask for? To this day there are no really satisfactory substitutes for some applications from which asbestos has been banned.)

The fibers are not just fine, they are ultra-fine: The ends of the natural fibers taper down to molecular sharpness, with a tip that is literally no more than a few atoms across. Lodged in the body, most commonly in the lungs when stray fibers are inhaled, these tips can worm their way into individual living cells and tickle the DNA in a way that no blunt artificial fibers can.

The ability to touch, and damage, DNA makes asbestos fibers potent carcinogens: Remarkably, unlike virtually all other carcinogens, they cause cancer purely mechanically, not chemically or by radiation. They literally poke the strands of DNA in a living cell without killing the cell. Topping off their deadly potential, asbestos fibers, unlike for example modern fiberglass fibers, last pretty much forever in the environment of the lungs. Fiberglass is said to dissolve after a few months in the lungs, and in any case isn't sharp enough to cause molecular-level damage (at least, that's what people think now, we'll see how the evidence stacks up in another 50 years). But asbestos fibers will sit there for decades on end, firmly lodged in the deepest recesses of the lungs, just waiting for some unlucky DNA to happen by.

In principle asbestos could cause cancer anywhere in the body, but it's the lungs that are most vulnerable. As with many hazards, its layer of dead cells protects the skin from asbestos, as does the lining of the gut. But in the lungs the living cells are right on the surface, vulnerable to anything that finds its way past the nose and sinuses.

The most serious disease caused by asbestos is mesothelioma, a form of cancer. If you look up mesothelioma in google, you will find lawyers, lawyers, and more lawyers. Everywhere you look, it's lawyers as far as the eye can see. Even websites that seem to be purely informational or medical in nature will, on closer examination, turn out to be sponsored by a law firm. The reason of course is that there is big money in mesothelioma, specifically in suing any and every company that ever had its doorstep darkened by a product containing asbestos in any form.

There is probably some guilt in the asbestos industry. The real truth will most likely never be known, since to admit it would mean instant financial ruin for anyone who spoke, but my guess is that some people, including some senior people at large companies, knew pretty well that asbestos was harmful, and instead of immediately shutting their companies down and putting hundreds of people out of work, they tried to hide the evidence and thus condemned more workers and customers to death. (Business is complicated, much like life.)

But the current orgy of asbestos litigation is clearly targeting people far from any reasonable definition of guilt. Lawyer's websites list literally hundreds of companies and job sites, including small plumbing distributors, hospitals, schools, and even court houses. All places where asbestos was manufactured, sold, handled, or used. All places liable to being sued for millions of dollars by someone who wishes to hold them accountable for the disease that is slowly but surely killing them.

Saying that a small plumbing company that sold or installed asbestos insulation is liable for the illness of its workers or customers throws common notions of liability on their head. These small business people had no more reason to believe asbestos was dangerous than did their employees and customers: No one imagined it. No one considered it. No one would have believed it. And if some large companies had internal documents suggesting there was cause for concern, they certainly didn't share those with the local plumbing contractor!

A lot of good people have been ruined by asbestos litigation. But a lot of people have died because of asbestos, and juries tend to want to find a way to help sick people, even if it means extracting money from someone who did nothing wrong, someone whose only guilt is being in the wrong place at the wrong time. Which is to say, being the owner of a business that sold a legal product that they and everyone they knew thought was safe.

What would be a fair solution? Society benefitted from asbestos, society (which is to say the government) should pay to take care of those harmed by it. In most countries, that's just what happens (and not just for asbestos-related disease). But in America, we instead have a system in which we pick random companies and extort them for sometimes more money than they have, to enrich a few sick people beyond any reasonable need, while diverting a large percentage of the money to lawyers who, much as some people might wish it, don't even have mesothelioma. Those not lucky enough to find a target with deep pockets, or too honest to blame a blameless party for their misfortune, languish in poverty and pain until death takes them.

It makes about as much sense as throwing darts at a board to decide who pays for which disease: OK, Amtrack, you pay for lupus, General Motors gets colon cancer, Microsoft can take gastroenteritis, Chiquita gets mesothelioma, and for hives we will pick, oh, say, McDonald's. (Yes, Chiquita Bananas is on the list of companies targeted for asbestos litigation. The other company-disease associations I made up and have no basis in fact. So far as I know.)

One thing that is often missed in discussion of asbestos is that the minerals it comes from are beautiful! I bought a set of six absolutely stunning mineral samples representing the range of natural sources for this amazing product.

The photo associated with this text is of Actinolite, one of the most potently carcinogenic forms of asbestos. Its sharp, needle-like fibers make it especially dangerous. The samples below represent all the major natural sources of asbestos fibers.

Oxygen Aerogel

Larger | Spin | 3D Aerogel.
Guitars used to just be called guitars, but then electric guitars were invented and you had to start calling regular guitars "acoustic guitars" to distinguish them from electric guitars. Same thing with gels. A gel, as in gelatin, used to mean a sparse three-dimensional web of solid material supported by a liquid solvent. Now you have to call that a "solgel", to distinguish it from an "aerogel", in which the liquid solvent is replaced by air.
Aerogels are very, very light, a tenth of a gram per cubic centimeter or less (for comparison water is one gram per cc). They are often referred to as frozen smoke, an apt description if you've ever held one.
But the often-made claim that they are the least dense solid material strikes me as suspect. They are also said to have a very large internal surface area, and it seems to me that if something has internal surface area, then it's not solid.
While aerogels have a very modern NASA air about them, they are actually quite old: In the 1950's a model of refrigerator was available that used aerogel insulation!

Oxygen Venus Flower Basket

Larger | Spin | 3D Venus Flower Basket.
This is a sea creature, a sponge of sorts, that grows a glass skeleton. That's right, the skeleton is made of what amounts to fiberglass. Isn't that the most amazing thing you've ever heard of? I suppose it shouldn't be any more amazing than us growing a calcium phosphate (actually calcium phosphate foam) skeleton, but it is to me.
Not only is the skeleton glass, the fibers it's made of are said to be superior in some ways to man-made fiber optics, and of course they are grown at low temperatures, something people, as of this writing, have no idea how to do.
And to top it off, this creature has one of those classically bizarre life cycles one can only stand in awe of. Each Venus Flower Basket is usually inhabited by a mating pair of bioluminescent shrimp. The shrimp entered the sponge when they were small, and are now too large to ever leave, but their offspring can swim out the openings to find their own sponges to set up permanent housekeeping in. Mated for life (whether they like it or not), the shrimp feed on the remains of food filtered by the sponge, while the light they generate is thought to attract more such food to the sponge.
Oh, and these things are dirt common, and can even be grown in home aquariums. We really do live on one of the most amazing planets I'm sure.

Larger | Spin | 3D Aeschynite.
The card that came with this shale-like blackish mineral says the following about the name: "From Gk. aeschyne, shame, alluding to the inability of chemists at the time of its discovery to separate some of its constituents". Hm, I wonder if it was the chemists who came up with this name, or the geologists who gave it to them to analyze.
This specimen is from Molland in Iveland, Norway. I bought it for its thorium content: Not that many minerals contain thorium and I'm trying to collect them all.

Reader Magnus Alvestad sent this interesting information about Iveland:

Hi. I noticed that your Aeschynite sample is from Iveland in Norway. The small community of Iveland is actually famous for their mines and minerals. Here's a folder with some information about a local exhibition. They also have at least 5 mines that are open to the public for a small price, where you can dig for minerals yourself.

I actually bought this crystal by mistake: I was going through mindat.org looking up the name of every single mineral that contains thorium, then searching on eBay to see if I could buy one of them. (I needed more pictures of thorium crystals to use for the short-lived radioactive elements that appear in the thorium decay chain.) For some reason I got confused and bough this one too: It's titanium dioxide with no hint of anything radioactive. But it's pretty just the same!

Oxygen Sapphire boule

Larger | 3D Sapphire boule.
This is a "flame fusion" sapphire crystal boule, such as might be used to create synthetic cut gemstones. Flame fusion means a fine powder of aluminum oxide (the base material sapphires are made of) is blown through an extremely hot flame and onto a seed crystal. The molten droplets, somewhat amazingly, follow the pattern of the seed crystal and slowly accumulate into a large, single crystal of sapphire.
The slight pink cast in this boule comes from a 1% impurity of titanium. Impurities determine the colors of most gemstones, and are, for example, responsible for the difference between rubies and sapphires, both of which are made of aluminum oxide.

Oxygen YAG boule top

Larger | Spin | 3D YAG boule top.
YAG stands for yttrium-aluminum-garnet: It's used to make lasers and can be doped with various elements to create different colors. This green one, for example, is doped with chromium.
The conical shape is similar to that of my silicon boule top, presumably because they are made by similar crystal-growing procedures. A crystal begins growing from a seed, expands out until it reaches the diameter of the melting pot is being pulled from, and then continues to grow as a straight-sided cylinder as it is pulled slowly out. Only the full-diameter portion of the rod can be used, so the cone at the start becomes waste and ends up with someone like me. (Actually, even this waste is quite valuable, probably because it can be melted down and reused. But Max found a nice company willing to sell us the cutoffs for a reasonable price.)

Oxygen Amber with bugs

Larger Amber with bugs.
I picked this piece of amber out of literally thousands available at a big fossil show because it was really big, really cheap, and it had bugs in it. It's important to have bugs in your amber if you want to extract DNA and recreate dinosaurs, or impress the kids. I'm told that given the low cost this is probably "copal", not true amber, but hey, it's got bugs in it. Copal is much younger, only a few thousand years rather than potentially millions of years.

And it does have some really great bugs! Here's a close-up of one, which is about 1/4 inch in overall size:
Amber Bug

I don't really know what the chemical composition of amber/copal is, but it's an organic resin which means it must contain carbon and hydrogen, and I figure it probably contains at least some oxygen, so I've listed it as being composed of those three elements, with carbon being the dominant one. Feel free to correct me if you know better.

In preparation for my coffee table book The Elements, I had my assistant Nick re-photograph this sample to my new, higher standards. Naturally it fell of the stand and broke into several pieces, which you can see here:

The metal beryllium is named after this mineral. I used to say here that beryl was named after beryllium, but reader Jeffrey Shallit kindly pointed out the absurdity of that notion, since the mineral was known and named long before the metal. He writes:

The word beryl comes from ancient Greek and according to the OED, first appeared in English in 1305. But beryllium was not discovered until 1797 and the word "beryllium" did not appear in English until 1863.

Beryllium the metal is fairly plain looking and toxic, while beryl the mineral is quite beautiful and comes in a great variety of shapes and colors.

En observant les relations entre les solides de Platon, il est possible de noter que l’icosaèdre est l’inverse précis du dodécaèdre. C’est-à-dire, si vous connectez les points centraux des 12 pentagones qui constituent l’élément éthérique, vous aurez créé les 12 coins de l’icosaèdre aqueux. nC’est intrigant car ce que nous avons pu observer jusqu’à présent de l’éther indique qu’il se inclus effectivement comme un fluide. Certes, la mesure et l’observation de l’éther s’est vérifiée assez dur jusqu’à présent, en raison de son omniprésence. Comment mesurer quelque chose dont on ne peut s’échapper ? Et si nous ne pouvons pas le mesurer, de quelle manière pouvons-nous être sûrs qu’il existe ? nNous avons peu de mal à mesurer les autres composants : la masse cinétique de la terre ; les réactions chimiques rendues solubles par l’eau ; la chaleur rayonnante du feu ; les volts du vent électrique. Celles-ci s’observent plutôt facilement, ‘ continuellement ouvertes à notre regard ‘ comme elles le font. Mais l’éther super subtil échappe à une détection facile. ‘ n
