  • Nuclear bonding has similarities to chemical bonding

    Robert Hayes | Published: Fri, Oct 25, 2013

    Perhaps the simplest of all nuclear particles is the proton.  This is a positively charged subatomic unit of mass which is found in the nucleus of all atoms.  In fact each element is defined by nothing more than the number of protons present in its nucleus.  A single proton all by...

  • Nanotechnology today is mostly materials

    Robert Hayes | Published: Fri, Oct 11, 2013

    When you hear the word nanotechnology, do you think of hoards of invisible microscopic robots collectively acting out some Hollywood scheme?  At the present time in our technology, there are some machines which have been constructed in the nanometer size scale.  That said, there are...

  • Acids and bases; what are they and why are they in your cupboard, laundry room and garage

    Robert Hayes | Updated: Sat, Oct 26, 2013

    Ever wonder how an acid dissolves something or what would happen when you mix an acid with a base?  Well the answer to the last question is pretty easy, mixing an acid with a base generally creates a salt.  Understanding why requires some understanding that will also lend to the answer...

  • Oscilating springs and vibration are everywhere and virtually permeate science

    Robert Hayes | Published: Fri, Sep 27, 2013

    When you think of a metal spring, does this make you think of a slinky or perhaps a vehicle shock absorber?  Truth is, the underlying mechanics of a vibrating spring are not only simple but permeate all of science from the celestial to the subatomic.  Springs play a critical role in...

  • What does probability matter?

    Robert Hayes | Published: Sat, Sep 21, 2013

    Ever wonder what probability is, maybe why some poker hands are worth more than others or perhaps even what the odds are on some other random outcome?  The simplest and least descript definition for probability is a ratio of counts.  The numerator of the ratio is the number of ways you...

  • Interpreting test failure rates can be tricky

    Robert Hayes | Published: Sat, Sep 14, 2013

    If you were to rely on a test that was 95% accurate, you might think that is a reasonably good test.  This is a common statistical confidence level used by statisticians, engineers and scientists worldwide but interpreting the result may leave you a bit snookered.  To start off with,...

  • "Let's make a deal" Paradox (as told by Marilyn Vos Savant)

    Robert Hayes | Updated: Fri, Sep 27, 2013

    There has been a recurring contention on a correct prediction by the genius columnist Maralyn Vos Savant in the parade magazine (a weekly insert in this newspaper).  Back in 1990, she made a prediction about the odds for a particular game on the popular TV game show The Price is...

  • Irradiation of food is a safe means for preservation

    Robert Hayes | Published: Sat, Aug 31, 2013

    A cost effective method of killing both E-coli and salmonella bacteria from food in a safe way is available for many foods.  This method is that of exposing the food to large doses of ionizing radiation, in much the same way that medical utensils are sterilized when using this...

  • Particle accelerators serve in medicine and science

    Robert Hayes | Updated: Mon, Aug 26, 2013

    Particle accelerators are used in medicine, research and industry for a variety of applications.  Some can even be used for homeland security in detecting smuggled nuclear materials or for sterilizing medical instruments.  The very microwave ovens found in our kitchens use a very...

  • Environmental radiological contamination

    Robert Hayes | Published: Sun, Aug 18, 2013

    When concentrated forms of radioactivity find themselves in the environment, or any accessible areas to people, this is known as radioactive contamination.  The radioactivity has to have been concentrated before this can really be considered as such because technically all things are...

  • Nuclear energy has a long list of benefits

    Robert Hayes | Published: Sat, Aug 10, 2013

    There are a lot of fears commonly held by people who oppose nuclear energy.  Some feel that a nuclear power plant can explode like a nuclear bomb or that nuclear energy is bad for the environment or perhaps even not safe.  Technically, a nuclear power plant could have a melt down under...



Dr. Robert Hayes


This column explains modern engineering and technology from quantum mechanics to electrodynamics with emphasis on nuclear science. Dr. Hayes is very excited about physical science and will attempt to infect you with this interest as well.
