Pi is a Palindrome

I know the last few digits of Pi...

Inside a mathematical singularity where infinity ends, where two parallel lines meet in Euclidean space, it turns out Pi is a Palindrome.  :-)

Daylight Saving Time is Upon Us

Daylight Saving Time is upon us tonight - Sunday, March 12th, 2017 at 2am.  Don't forget to turn your "non-smart" clocks forward an hour.

I like to remind myself with, the following which helps me remember which direction to turn the clocks to.

"Spring" forward into action, and "Fall" back to sleep.

Why Fundamental Forces Are Difficult To Explain

Richard Feynman was asked Why Magnets Repel Each Other?  His answer sums up why it is so difficult to explain physics.  It requires accepting other answers as truth, or you rabbit hole down an endless path of why questions.  We take for granted that when your hand pushes against a chair it moves.  But your physical hand never actually touches the chair.  The electrical forces repel the chair at a minuscule level.  The magnetic force is very similar to the electrical forces.  The iron atoms of a magnet are all lined up so the magnetic forces are amplified to where they cross a greater distance.

Electronics Merit Badge

Electronics is the science that controls the behavior of electrons so that some type of useful function is performed. Today, electronics is a fast-changing and exciting field.


  1. Describe the safety precautions you must exercise when using, building, altering, or repairing electronic devices.
  2. Do the following:
    1. Draw a simple schematic diagram. It must show resistors, capacitors, and transistors or integrated circuits. Use the correct symbols. Label all parts.
    2. Tell the purpose of each part.
  3. Do the following:
    1. Show the right way to solder and desolder.
    2. Show how to avoid heat damage to electronic components.
    3. Tell about the function of a printed circuit board. Tell what precautions should be observed when soldering printed circuit boards.
  4. Discuss each of the following with your merit badge counselor, and then choose ONE of the following and build a circuit to show the techniques used:
    1. Tell how you can use electronics for a control purpose, and then build a control device circuit.
    2. Tell about the basic principles of digital techniques, and then build a digital circuit. Show how to change three decimal numbers into binary numbers and three binary numbers into decimal numbers.
    3. Tell about three audio applications of electronics, and then build an audio circuit.
Show how to read the schematic diagram of the project you chose and, to the best of your ability, explain to your counselor how the circuit you built operates.

  1. Do the following:
    1. Show how to solve a simple problem involving current, voltage, and resistance using Ohm’s law.
    2. Tell about the need for and the use of test equipment in electronics. Name three types of test equipment. Tell how they operate.
  2. Find out about three career opportunities in electronics that interest you. Discuss with and explain to your counselor what training and education are needed for each position.

Arduino is a Guy

"Arduino will then stop talking about himself in the third person."

Apperently Arduino is a guy and illeistic too.
