MQTT is Messaging for IOT

MQTT is an acronym that stands for Message Queue Telemetry Transport. It is a communications or messaging protocol for Internet Of Things (IOT) devices. If we want our toaster and coffee maker and doorbell to talk to each other, they will most likely be using MQTT. [when the doorbell rings to announce guests, start the […]

Navigation in the Asteroid Belt

Navigation requires time and position data and the ability to calculate and plot a course. Historically, we have used “fixed” points like stars and buoys and beacons and landmarks and we plotted courses to fixed destinations. More recently we have learned to use a network of Global Positioning System (GPS) satellites. The satellites move constantly […]

Autonomous Ships

Ships that can operate themselves are in our future. Solving navigation and normal operations problems are not difficult with modern technology. Adapting “fly-by-wire” methodology from aviation to ocean going ships will allow all the ships systems to be controlled from a computer interface instead of manual controls. In fact, many modern ships are already in […]

Smart Cities

We have smart phones, meters, watches, and the “internet of things” that promises to embed “smartness” into most household and business objects and connect them. The same concept applied to city infrastructure, is now being called “smart cities”. City infrastructure includes: water supply, electricity, waste management, transportation, communication, emergency services, law enforcement, education, healthcare, zoning, […]

Smart Stuff

We are building intelligence into a constantly expanding list of everyday household items. It started with smart phones, and we now have smart meters, smart light bulbs, smart locks, smart watches, smart clothing and smart appliances and gadgets of all types. Any device that can use sensors to collect data, make decisions about how to […]

Galactic Communications Using a Gravitational Lens

Gravitational lensing is the process of a large mass bending light from a distant source. Einstein predicted this and astronomers can now detect it. By placing an optical collector or a radio antenna at a distance of 550 AUs or greater from our Sun, it can be used as a lens to focus detail from […]

Defining the Singularity

Considering what changes the singularity is bringing is difficult because by nature, a singularity defines a threshold beyond which lies limited vision or understanding. However, there are some common sense assumptions that we can make regarding the singularity based on the conditions that predict it. The rate of change of technological development and of increasing […]
