Holograms are images that seem to jump out of a flat surface, full of depth that you can experience through perspective changes and parallax cues. The three-dimensional effect that a hologram creates comes from the three dimensional light field that’s created when photons diffract through the interference pattern on a holographic plate. It’s essentially a structure made of light that gets projected out into space when the seemingly random pattern of features on the plate interact with each other.
Researchers at MIT have developed a new camera that can photograph a trillion frames per second. Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.
A home battery that is cheap, durable, safe and as big as you like that could store solar or wind power is closer to reality. Harvard University researchers report that they have tested a “flow battery” that uses cheap and abundant chemical elements, can be operated with plastic components, will not catch fire and can operate at 99 percent efficiency.
Business-oriented virtual digital assistants (VDA’s) have the potential to help relieve employees from mundane and time-consuming tasks. Digital assistants have the ability to positively impact lives using what market intelligence firm Tractica describes as “the fusion of speech recognition, natural language processing (NLP), and artificial intelligence (AI) and hold the potential to have a transformative impact on user interfaces in the mobile, automotive, connected home, and enterprise domains, among others.”
Machine learning plays a part in your everyday life. When you speak to your phone (via Cortana, Siri or Google Now) and it fetches information, or you type in the Google search box and it predicts what you are looking for before you finish, you are doing something that has only been made possible by machine learning.
