      What is a Laser Profilometer?

      A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface

    • Linear Particle Accelerator

      Linear Particle Accelerator

      A linear particle accelerator is a large device that can speed up electrons, ions, or other particles and slam them into a target in order to release subatomic particles and radiation. Sensors then record these by-products, send their data to a central computer system that creates a digital, 3D image of the particle, and labels

      Future Flying Cars

      A flying car is a personal flying machine that does not require special equipment, runways, or traffic routes. Flying cars differ from commercial aircraft such as airliners, helicopters, and jets. Flying cars are designed to hold only a few people and are no larger than a regular automobile. While flying car designs have been in

    • Paraffinum Liquidum

      Paraffinum Liquidum

      Paraffinum Liquidum (mineral oil) is a petroleum by-product and is created through distillation. Mineral oil is completely transparent and is basically a liquid form of petroleum jelly. It is produced in large quantities and is used in many different ways all over the world, mostly due to its low toxicity and low cost. Mineral oil

    • How Do Xenon Lights Work?

      How Do Xenon Lights Work?

      Xenon is a noble gas–found all the way to the right on the periodic table of elements–that is odorless, colorless and heavy. It has many different uses, but one of the biggest uses that it has is the use in light bulbs. The reason for this is because when xenon is excited, it gives off

    • How a Volcano Erupts

      How a Volcano Erupts

      A volcano is any opening in the Earth’s surface that allows molten rock and volcanic gases to escape from far below the Earth’s surface. Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean floor, ice volcanoes, which have been found on a variety

    • Holographic Memory

      Holographic Memory

      Holographic memory is a storage device that is being researched and slated as the storage device that will replace hard drives and DVDs in the future. It has the potential of storing up to 1 terabyte or one thousand gigabytes of data in a crystal the size of a sugar cube. Brief History of Holographic

    • Mannitol Salt Agar

      Mannitol Salt Agar

      In order to grow a bacterial culture in a lab, a growth medium has to be used to provide the right environment. Mannitol salt agar is a popular bacterial growth medium that biologists use to grow halphile bacteria (these grow fast in high salt concentrations) and can tell the difference between non-pathogenic and pathogenic Staphylococcus

    • What Are Ceramic Briquettes?

      What Are Ceramic Briquettes?

      Ceramic briquettes are special accessories for gas grills that help consume less fuel. These briquettes come in various styles and can help to give the classic grilling to meats and other dishes that are prepared over the grill. The ceramic briquettes also help to distribute the heat more evenly and this is effective in producing heat for

    • What is an Anechoic Chamber?

      What is an Anechoic Chamber?

      An anechoic chamber prevents sound, radio signals, and electromagnetic waves from echoing  in a room. Anechoic chambers often test antennas, measure the direction of sound, or record music. Anechoic chambers are found all over the world, especially in universities, and can be as large as an aircraft or as small as a car. Full-anechoic chambers
