  • A car spark plug firing.  The spark plug is the trigger that causes the gasoline to burn at a specific time in the cars internal combustion engine.  The spark plug fires and give the gas/air mixture the activation energy to start to burn.  This is a critical component in the thermodynamic cycle of an internal combustion engine.  A dirty or poorly adjusted spark plug will cause an engine to mis-fire, or fail to run.

  • This is a demonstration used to show the principle of heat of compression.  This is the physical process that makes Diesel engines possible.   To work the demonstration, a small sample of cotton is placed in the chamber.  The plunger is then forced down and held in place with considerable force.  The air in the chamber is forced into a very small volume, thus heating the air above the flash temperature of the Cotton.  The same process take place in a Diesel engine, but the fuel is oil.  The Diesel engine is much more efficient that a gasoline engine. .

  • Marble ws heated in a lime kiln to convert teh mineral to lime.  This is the material used in a limelight lamp.  Limelight also known as calcium light is a type of stage lighting once used in theaters.  A bright light is created when a sample of quicklime (calcium oxide). The light is produced by  incandescence.  The historic use of the light still services as someone in the public eye is still said to be ?in the limelight.? .Lime is produced by heating calcium carbonate until the extra carbon and oxygen atoms are driven off leaving just the calcium oxide.  This process is very easy and takes place in a lime kiln. Lime can be made from sea shells, chalk, and many types of rock - including marble.

  • The patterns in smoke are studied by illuminating the smoke with a scanning laser. The laser shows the motion in a 2D plain that is easier to study than the 3D motion. The coils represent cross section of fluid vortexes created by the convection currents from the hot smoke rising in the cool air. The source of the smoke is a stick of burning incense.

  • A false color SEM image of a Calcium oxalate crystal.  Even a small dose of calcium oxalate is enough to cause intense sensations of burning in the mouth and throat.  Commonly found in popular houseplants, such as Dumbcane, the crystals effects or symptoms may last for a week or more, making calcium oxalate crystals a non-desirable ingredient in medicinal cannabis.  It is surprising that calcium oxalate is rarely discussed in literature about medical marijuana (cannabis).  There crystals are fairly common in plants, as they make it hard for grazing animals to eat the plant. Image is 70 um wide.
