The Secrets of Ultrasonic Welding. Joining metallic materials to build things can be accomplished in a number of ways. Screws and bolts also known as fasteners are one way to go if you need only a single point of connection. Welding them together is another method that is used for larger structures or objects that […]

Science Fiction Promised Us 3D Billboards Without Glasses. Back to the Future Day” is October 21st, 2015 and this is as good a time as any to see what future predictions made in the 1980’s hit scifi movie ” Back to the Future II” might now actually be possible. There were many future inventions predicted […]

Small spacecraft are better right? The nature of spaceflight is entering some new territory. NASA has scrubbed the shuttle program and has moved to a model of outsourcing the actual transportation of goods and astronauts around inner space. Mars, it seems is still a NASA priority with the government agency testing some of the largest […]

Compounds and elements can have very different properties depending on the temperature the are subjected to and the pressures they are under. For example pure oxygen becomes poisonous after one atmosphere of pressure. Hydrogen has long been thought to become a metal at very high pressures.

Was Einstein Wrong? Albert Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This eventually led him develop his now famous special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and […]

The age of Nano-Electronics. In the last 50 years electronics circuits and devices have undergone a revolution not just in technology but also size. I mean computing power that was housed in multi-story buildings is now residing on a circuit the size of the head of pin. Now new research is taking what is possible […]

Producing the Perfect Image. I am always messing around with the lens on my camera, trying to select the perfect one for occasion and the shot that I want. Meanwhile my iPhone does not have a removable lens and takes almost as good of pictures. I guess that says something about my photography skills right. […]

The many uses of Ultrasound Technology – ( TeK-THinK) Ultrasounds are sound waves with frequencies higher than the upper audible limit of human hearing ( we cannot hear it). This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up […]

Communication Bottlenecks Can Lead to Failures in the Network. ( TeK-THinK) As the world’s population skyrockets to well over the 7.3 billion person mark and the number of cell phones per person is expected to reach 1.75. ( I have only one cell phone by the way) it is not hard to imagine that we […]

Fighting Mega Robots Like These Prove It is Possible. ( Tek-THinK) I am pretty sure I recognize the design of these killer fighting robots from the first Robo-cop movie in the 80’s. The movie was good at the time because it was the first time that the world caught a glimpse of what future robotic […]
