Aerogel

Also known as “Frozen Smoke“, Aerogelis

aerogel geek buy online gift science nerd

a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity. Nicknames include “frozen smoke”, “solid smoke”, “solid air” or “blue smoke” owing to its translucent nature and the way light scatters in the material; however, it feels like extruded polystyrene (Styrofoam) to the touch.

Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in “jellies” with gas without causing shrinkage.

Aerogels are produced by extracting the liquid component of a gel through super critical drying. This allows the liquid to be slowly dried off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. The first aerogels were produced from silica gels. Kistler’s later work involved aerogels based on alumina, chromia and tin dioxide. Carbon aerogels were first developed in the late 1980s.

EcoSphere

ecosphere gift geek buy online cheap funThe EcoSphere and “Original Ecosphere” are trademark names for sealed blown-glass miniature aquaria produced by Ecosphere Associates, Inc., of Tucson, Arizona, United States. Spherical or ovoid, the aquaria range from roughly baseball-size to soccer-ball-size. They are sold worldwide as scientific novelties and decorative objects.

The EcoSphere’s main visual appeal is provided by tiny red-pink shrimp, Halocaridina rubra, between 1/4 and 3/8 inch (or approximately a centimeter) in length. The shrimp swim energetically around the aquarium, eat the brown bacterial and algal scum on the glass, consume the filamentous green algae which sometimes forms a globular pillow in the water, and perch on a fragment of soft coral.

The main conceptual interest of these objects lies in the fact that they are materially closed ecological systems which are self-sustaining over a period of years. At room temperature, and with only low inputs of light, the algae produce oxygen which supports the shrimp and bacteria. Bacteria break down the shrimps’ wastes. The breakdown products provide nutrients to the algae and bacteria upon which the shrimp feed. The manufacturer states that shrimp live in the EcoSphere for an average of 2 to 3 years, and are known to live over 10 years.

A magnetic scrubber is enclosed in each EcoSphere. By passing another magnet over the outside of the glass, the owner can manipulate the scrubber to clean the inside of the EcoSphere

 Mars Rock (Martian meteorite)

mars rock buy onlineMartian meteorite is a rock that formed on the planet Mars, was ejected from Mars by the impact of an asteroid or comet, and landed on the Earth. Of over 61,000 meteorites that have been found on Earth, 120 were identified as Martian (as of May 21, 2013).[2] These meteorites are thought to be from Mars because they have elemental and isotopic compositions that are similar to rocks and atmosphere gases analyzed by spacecraft on Mars.[3]

The term does not refer to meteorites found on Mars, such as Heat Shield Rock.

On January 3, 2013, NASA reported that a meteorite, named NWA 7034 (nicknamed “Black Beauty”), found in 2011 in the Sahara desert, was determined to be from Mars and found to contain ten times the water of other Mars meteorites found on Earth.[1] The meteorite was determined to have formed 2.1 billion years ago during the Amazonian geologic period on Mars.

Gömböc

Science Geeks will love these gifts - Gombok - a convex three-dimensionalhomogeneous bodygömböc or gomboc (/ˈɡɒmbɒk/; Hungarian: [ˈɡømbøts]) is a convex three-dimensionalhomogeneous body which, when resting on a flat surface, has just one stable and one unstable point of equilibrium. Its existence was conjectured by Russian mathematician Vladimir Arnold in 1995 and proven in 2006 by Hungarian scientists Gábor Domokos and Péter Várkonyi. The gömböc shape is not unique; it has countless varieties, most of which are very close to a sphere and all have very strict shape tolerance (about 0.1 mm per 10 cm). The most famous solution has a sharpened top and is shown on the right. Its shape helped to explain the body structure of some turtles in relation to their ability to return to equilibrium position after being placed upside down. Copies of gömböc have been donated to institutions and museums, and the biggest one was presented at the World Expo 2010 in Shanghai, China.

Gallium

Gallium is a chemical element with symbol Ga and atomic number 31Gallium is a chemical element with symbol Ga and atomic number 31. Elemental gallium does not occur in nature, but as the gallium(III) compounds that are in trace amounts in zinc ores and in bauxite. Gallium is a soft silvery metal, and elemental gallium is a brittle solid at low temperatures. If it is held in the human hand long enough, gallium will melt, since it melts at the temperature of about 29.76 °C (85.57 °F) (slightly aboveroom temperature). The melting point of gallium is used as a temperature reference point. The alloy galinstan(68.5% gallium, 21.5% indium, and 10% tin) has the even lower melting point of −19 °C (−2 °F), well below the freezing point of water. Beginning with its discovery in 1875 through the era of semiconductors, gallium was used primarily as an agent to make alloys that melt at low temperatures. Then, gallium became useful in semiconductors, including as a dopant.

Today, nearly all gallium is used in electronics. Gallium arsenide, the primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuitsGallium nitride and indium gallium nitride, minority semiconductor uses, produce blue and violet light-emitting diodes(LEDs) and diode lasers.

Miracle Berries

Miracle Berries

Synsepalum dulcificum, also known as the miracle fruit, is a plant with a berry that, when eaten, causes sourfoods (such as lemons and limes) subsequently consumed to taste sweet. This effect is due to miraculin, which is used commercially as a sugar substitute. Common names for this species and its berry include miracle fruit,[2] miracle berrymiraculous berry,[2] sweet berry,[3][4][5] and in West Africa, where the species originates, agbayun,[6] taamiasaa, and ledidi.

The berry itself has a low sugar content[7] and a mildly sweet tang. It contains a glycoprotein molecule, with some trailing carbohydrate chains, called miraculin.[8][9] When the fleshy part of the fruit is eaten, this molecule binds to the tongue’s taste buds, causing sour foods to taste sweet. At neutral pH, miraculin binds and blocks the receptors, but at low pH (resulting from ingestion of sour foods) miraculin binds protons and becomes able to activate the sweet receptors, resulting in the perception of sweet taste.[10] This effect lasts until the protein is washed away by saliva (up to about 60 minutes).[11]

The names miracle fruit and miracle berry are shared by Gymnema sylvestre and Thaumatococcus daniellii,[2]which are two other species of plant used to alter the perceived sweetness of foods.

Klein Bottle

Klein Bottle

In mathematics, the Klein bottle /ˈkln/ is an example of a non-orientable surface; informally, it is a surface (a two-dimensional manifold) in which notions of left and right cannot be consistently defined. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is asurface with boundary, a Klein bottle has no boundary (for comparison, a sphere is an orientable surface with no boundary).

The Klein bottle was first described in 1882 by the German mathematician Felix Klein. It may have been originally named the Kleinsche Fläche (“Klein surface”) and that this was incorrectly interpreted as Kleinsche Flasche (“Klein bottle”), which ultimately led to the adoption of this term in the German language as well.

Giant Plush Microbes

Giant Plush MicrobesMost folks never realize how cute microbes can be when expanded 1,000,000 times and then fashioned into cuddly plush. Until now, that is. Keep one on your desktop to remind yourself that there is an “invisible” universe out there filled with very small things that can do incredible damage to much bigger things. Then go and wash your hands. Lather, rinse, repeat.

Ferrofluid

Ferrofluids are found in everything from speakers to hard drivesferrofluid (portmanteau of ferromagnetic, and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field.

Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of nanoparticles is weak enough that the surfactant’s Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually[1] do not retainmagnetization in the absence of an externally applied field and thus are often classified as “superparamagnets” rather than ferromagnets[citation needed].

The difference between ferrofluids and magnetorheological fluids (MR fluids) is the size of the particles. The particles in a ferrofluid primarily consist of nanoparticles which aresuspended by Brownian motion and generally will not settle under normal conditions. MR fluid particles primarily consist of micrometre-scale particles which are too heavy for Brownian motion to keep them suspended, and thus will settle over time because of the inherent density difference between the particle and its carrier fluid. These two fluids have very different applications as a result.

Ferrofluids are found in everything from speakers to hard drives, but it’s much more fun to play with when when you’ve got a puddle of it naked and out in the open.

Proof: The Science of Booze Hardcover – May 27, 2014

Humans have been perfecting the science of alcohol production for ten thousand years, but modern scientists are only just beginning to distill the complex reactions behind the perfect buzz. In a spirited tour across continents and cultures, Adam Rogers puts our alcoholic history under the microscope, from our ancestors’ accidental discovery of fermented drinks to the cutting-edge laboratory research that proves why—or even if—people actually like the stuff.

From fermentation to distillation to aging, Proof offers a unique glimpse inside the barrels, stills, tanks, and casks that produce iconic drinks. Rogers ventures from the whiskey-making mecca of the Scottish Highlands to the most sophisticated gene-sequencing labs in the world—and to more than one bar—introducing us to the motley characters and evolving science behind the latest developments in boozy technology. He uncovers alcohol’s deepest mysteries, chasing the physics, molecular biology, organic chemistry, and even metallurgy that power alcohol production, and the subtle mixture of psychology and neurobiology that fuels our taste for those products.

With intoxicating enthusiasm, Rogers reveals alcohol as a miracle of science. If you’ve ever wondered how exactly your drink of choice arrived in your glass, or exactly what will happen to you once you empty it, Proof makes an unparalleled drinking companion.
