Acasta Gneiss: this polished sphere is a sample of the oldest known rock on Earth-  dated at 4.03 billion years old based on multiple and mutually consistent radiometric dating techniques. This rock is only found in the Northwest Territories of Canada and was collected by Yellowknife resident Mark Brown.

Superellipsoid: the
@physicsfun

Superellipsoid: the "super egg" is a mathematical creation of Danish scientist and artist Piet Hein (also the inventor of the Soma cube puzzle). The equation of the superellipse is that of a regular ellipse, but raising both sides to the power of 2.5 instead of 2- the resulting curve had a flattened end that allows the superellipsoid to stand upright. The superelljpse has found use in architecture and design. This super egg is made of stainless steel. ➡️ Follow the link in my profile for info on where to buy this and other amazing items featured here on @physicsfun #science #math #art #mathtoy #mathstoy #PietHein #Hein #physics #physicstoy #superellipse #superegg #volumeofrevolution #ellipse #somacube #sergelssquare

Cartesian Devil: strange blown glass Cartesian diver- water enters and exits through its tail which is wrapped sideways around it, so when the pressure is released the water devil spins. Pressure on the bottle cap forces water into the diver, which compresses the bubble in its head allowing it to sink. When the pressure is released the bubble regains its size expelling the water through the tail and the devil spins and rises.

Extreme Viscosity Sculpture: a heavy ball bearing descends through a very viscous fluid while a bubble of air ascends in this weird and wonderful vintage kinetic art desk toy I found on eBay. It takes almost two full minutes for the ball to move to the bottom as the air bubble moves to the top- shown here at 2X speed to fit the Instagram time limit. Note the strange phenomena that occurs when the ball bearing passes by the bubble. ➡️ Follow the link in my profile for info on where to buy many of the physics toys featured here are on @physicsfun #kineticart #viscosity #drag #viscous #fluiddynamics #physicsfun #gravity #physics #physicstoy #bubble #buoyancy #Archimedesprinciple #science #art #desktoy #scienceisawesome

The Orb Drop: @orbdrop a marble run with a unique marble transport system using a magnetic conveyer gear assembly to bring the steel balls to the top. Gravitational potential energy is transformed to the kinetic energy of the orbs as they loop and negotiate the banked turns of the snaking track. Two AA batteries and a small motor power the transport assembly. ➡️ Follow the link in my profile for more info and where to get an Orb Drop kit and other amazing items featured here on @physicsfun #physics #physicstoy #gravity #gravitywell #orbdrop #angularmomentum #kinetic #kineticart #kineticenergy #marblerun #science #scienceisawesome

Vintage Flicker Bulb: the flexible 15 Watt carbon filament in this bulb oscillates back and forth producing a slight resemblance to a flickering flame. A magnet attached to the side of the bulb pushes on the magnetic field produced by the current flowing in the filament. Since US house mains current is AC at 60 Hz the current flow changes direction many times a second which in turn allows the magnet to push the filament back and forth at the same rate. Magnetic fields can add and subtract- here a strong magnet is used to temporarily make the filament go into chaotic oscillations.

Peridotite Xenoliths: here before you are chunks of Earth's mantle material from 50 kilometers or deeper below the surface, far below the deepest hole ever drilled at 12.3 km (a great effort which didn't even break through to the mantle). However, green peridotite crystals of olivine and pyroxenes are sometimes brought to the surface by viscous lava in the form of xenoliths- inclusions in the volcanic basalt as seen in this sample. This piece was collected from Peridot Mesa in the San Carlos Volcanic Field of AZ. Amazing sample of the inaccessible Earth's interior. ➡️ Follow the link in my profile for more info and how to buy a piece of the Earth's mantle material and other amazing items featured here on @physicsfun #geology #rockhound #geophysics #geophysicstoy #mantlexenolith #xenolith #physics #physicstoy #peridotite #olivine #peridot #mineral #volcanic #lava #science #scienceisawesome

Polage Display: art with polarized light using polarizing sheets and cellulose to create changing forms and colors. Rotation of the filter allows the artist to produce colorful  metamorphosis. This piece was created by Austine Wood Comarow- the main developer of this art form- as part of a campaign to promote Maui Jim polarized sunglasses. Light has an orientation, denoted as polarization, and a polarizing filter can be used to block certain orientations. The colors in polage come from how the molecular structure of plastics can rotate the polarization of any light that passes through- but only light corresponding to yellows and greens gets rotated in plastic, reds and blues not so much. Polage uses different layers of plastic to rotate the light, and then polarizing filters are added to allow only certain frequencies (colors) of light through. ➡️ Follow the link in my profile for more info about the physics of polage and where to get art featured on @physicsfun  #polarizer #polarizedlight #light #optics #physics #physicstoy #kineticart #electromagnetism #polage #science #linearpolarization #scienceisawesome #AustineWood #mauijim #polarizedsunglasses @austine_studio
