There is an indication of the need for additional workers in the technical Workforce.  SEMI [Ref. 1] has indicated there is a shortage of 80,000 to 100,000 semiconductor workers.  With the surge in creating additional semiconductor fabs that number is sure to grow.  The growing Space industry is also in need of trained workers.  The same can be said of the med-bio industry.    We don’t have the quantity of skilled workers, so where do we get them.  Part of the solution is to recognize that we, ourselves, have created the problem.   In the early ..read more

There are times when there is an established technology that undergoes a modification.  There are also times when different technology approaches compete.  In the early days of distributed electricity, Direct Current (DC) came to forefront.  It was understood and built on knowledge from working with various types of sources, some of which we variations of the battery.  Alternating Current (AC) had a more complex insertion into every day life due to the fact, that AC did not have the mathematics that would enable the creation of a supply system for AC power.  Nikola Tes ..read more

Last year, the November blog mentioned some of the challenges with Generative Artificial Intelligence (genAI).  The tools that are becoming available still need to learn from some existing material.  It was mentioned that the tools can create imaginary references or have other types of “hallucinations”.    Reference 1 quote the results from a Standford study that made mistakes 75% of the time involving legal matters.  They stated: “in a task measuring the precedential relationship between two different [court] cases, most LLMs do no better than random guessing.” T ..read more

Two-Dimensional Meta-Materials

The term meta-materials refers to materials that are created by producing material structures that do not occur in nature and also can be created with structural complexity that also would not occur in nature. Graphene has long been a material of interest. For a long time, the issue with graphene has been the ability to produce it in large areas without any defects. The work done in Reference 1 was focused on evaluating a nano electronics platform based on graphene. The interest is because the technology is compatible with conventional semiconductor manufacturing. This work was based on the re ..read more

Over the years, we have witnessed the issues or multiple peer-reviewed papers being recalled.  A recent example as reported in numerous places, Reference 1 states: “The Dana-Farber Cancer Institute (SCFI), an affiliate of Harvard Medical School, is seeking to retract six scientific studies and correct 31 others that were published by the institute’s top researchers, including its CEO. The researchers are accused of manipulating data images with simple methods, primarily with copy-and-paste in image editing software, such as Adobe Photoshop.” There were allegations of data manipulation in ..read more

Artificial Inelegance (AI) seems to be in the news with promises of a tremendous amount of benefits for the average person.  Specifically, “Generative AI” will be the foundation of all these benefits.   Before we start believing all the super benefits from Generative AI programs like ChatGPT, it is instrumental to understand the background behind these newer programs. In the early 1980s, personal computers started becoming a tool that was adopted by large businesses.  The development of spreadsheet programs, like SuperCalc, provided the ability to analyze large amounts of d ..read more

There is no question that we live in a digital world.  What does that mean?  Is there another world?  What is the difference?  We live in a world of computers.  Computers are based on components of electrical circuits.  The basic part of the circuit is defined by either being “on” (conducting electrical signals) or “off” (not conducting).  Each of these basic circuit parts in considered a “bit”.  So, a 32 bit controller divides the control in to 32 steps, while a 64 bit has 64 steps.  Notice, the term “steps”.  If one considers a child’s slide ..read more
