Great inventions exist in the world of audio and music: stereo, surround sound, and holophonics, all known as 3D sounds. Although holophonics can be confused with surround sound because it tries to create a surrounding with sounds from different sources, holophonics have a completely different system and are only emitted through a stereo system, which when used with headphones and creates a sense of three-dimensionality.

The technological revolution is progressing every day at a faster pace. Virtual reality is no longer enough, now augmented reality is necessary. But what is augmented reality? Well, it's the option to view objects in 3D and at the same time as a real image with just a helmet, goggles and a special computer program. Currently it is being used for video games, architectural drawings, artwork and even medicine.
Host Nerdo Cavernas discusses the advancements made in the audiovisual world. Some areas of focus include editing and finishing software, 2D and 3D titling, sophisticated color correction, image stabilization, tracking and inlay of high precision images, graphic creation, and design and processing of multiple image technologies.

Many viewers enjoy three-dimensional technology, but a few feel the need to look away. A number of neurological and visual conditions can cause someone to experience nausea. It's a type of motion sickness without the motion. Fred Bonato of St. Peter's College in Jersey City has spent years steadily tracking what he calls "cyber sickness.”
The transplanting of bone tissue, known as bone grafting, typically involves allograft, which is bone from a deceased donor, or autograft, which comes from the patient's own body. With support from the National Science Foundation, materials scientist Ramille Shah and materials engineer Adam Jakus are working to develop and improve synthetic materials available for bone grafting. Part of the "Science Nation" series.
At Virginia Polytechnic Institute and State University, Christopher Williams heads the effort to further advance 3-D printing with copper, a widely used conductor in electronics. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer. The printed copper product is then taken to a furnace to fuse the particles together. With support from the National Science Foundation, Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process.

Host Emily Graslie meets with Dr. Ryan Felice to discuss the 3-D surface scanner, which he uses to create digital representations of skeletal anatomy. He visits various museums and scans their collections hoping to help preserve research findings. Part of "The Brain Scoop" series.
Nate Ball uses science to develop mechanical devices that help improve life. Some of his designs push technology to its limits, like his portable, refrigerated vaccine backpack.
Elisa Konofagou, a bioengineer at Columbia University, believes ultra sound technology could become be a vital component in treating and perhaps curing degenerative brain diseases. One big problem associated with treating these diseases today is a chemical shield of sorts that protects the brain against chemicals in the blood. Unfortunately, it also keeps out many drug treatments. Konofagou believes ultrasound waves could be one key to turning the blood/brain barrier on and off.
Patients who have suffered devastating facial injuries sometimes go to great lengths to hide themselves from public view. At the University of Illinois at Urbana-Champaign, civil and mechanical engineer Glaucio Paulino saw the possibilities of combining engineering and medical skills to tackle the complex challenge of facial reconstruction. Part of the National Science Foundation Series “Science Nation.”
A giant video screen that takes up an entire wall, floor to ceiling, is allowing scientists to see details they've never seen before. Developed at Tufts University with help from the National Science Foundation, the Visualization Wall has a variety of applications. The "VisWall" offers a surgeon the opportunity to teach and practice surgical procedures on avatar renditions of the human body.
The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
With support from the National Science Foundation, biomedical engineer Bin He and his team at the University of Minnesota have created a brain-computer interface with the goal of helping people with disabilities, such as paralysis, regain the ability to do everyday tasks. Currently, they’re testing out their system using a flying object known as a Quadcopter, which is controlled with someone’s thoughts. Part of the National Science Foundation Series “Science Nation.”
In this episode, groups of citizen scientists use mobile technology to help save lives. Volunteers across North America measure precipitation, and their data is used by emergency managers to issue warnings during extreme weather conditions. In India, a phone app helps officials alert communities about killer heat waves. Citizen scientists also help collect data about Alzheimer's disease. They hope their data will aid the research process and lead to a cure. Part of "The Crowd and the Cloud" series.
While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro and nanometer length scales. At those sizes, 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. With support from the National Science Foundation, Brown University mathematician Govind Menon and Johns Hopkins University chemical and biomolecular engineer David Gracias are developing self-assembling 3-D micro and nanostructures which can be used in a number of applications, including medicine.
Speed, elegance, comfort, and many other factors are taken into account when creating a car. Car designers must be intentional in the creation of a great vehicle and ensure that all parts work together. Sports cars must have powerful engines, excellent chassis, strong suspension systems, and fuel efficient systems. Automotive technology ensures that consumers get more than just a pretty car.
Host Nerdo Cavernas visits the MotoPark XRP and explores the world of the motorcycle. The motorcycle industry has seen numerous advances over the years and has evolved into a profitable industry with great appeal to various outing options.
Hundreds of tools exist for the production of audiovisual products and when properly used excellent quality and beauty is delivered through image and sound. The host, Nerdo Cavernas, talks with experts and takes viewers into the world of audiovisuals.
Parakeet discusses the benefits of technology as a way of helping us. Amanda argues we should immerse ourselves in technology, and it should occupy every moment of life. The first guest, frog, complains duck doesn't answer her calls. Duck says the frog is addicted to technology and does nothing but call all day. The fleas show a documentary on the negative effects that the excessive use of technology has on humans. The celebrity guest, Batman, talks about technology as a tool that can't replace human relationships.
