I missed Pythagorean Theorem Day

How could I have missed this! A geek like me who took advanced mathematics classes as my electives in my graduate study in engineering electronics?

August 15, 2017 was Pythagorean Theorem Day. Why?:

Because 8/15/17 is 82 + 152 =172 OR 152 + 82 = 172

This is so mathematically unique because it does not occur all that often (unlike Pi Day which is every year).

We probably all know that Pythagoras, a Greek philosopher and mathematician was born around 569 BC and died around 475 BC. Pythagoras figured out a theorem which we celebrate today; c2 = a2 + b2

To see the uniqueness of this day, note that the next Pythagorean Theorem Day will be on December 16, 2020 (12/16/20 or 16/12/20): 122 + 162 = 202

The one following that will occur on July 24, 2025 (7/24/25 or 24/7/25): 72 + 242 = 252

Stay tuned for my EDN article coming shortly in which I will discuss the following:

  • How to Prove the Pythagorean Theorem in Antenna Analysis
  • The Dual Pythgorean Theorem and Bad Data Detection
  • From the Pythagorean Theorem to the definition of the derivative function
  • Educational Game Design on Pythagorean Theorem For Game Based Learning Using 6i’s Component
  • Reduction of Energy Consumption In WSN using the Generalized Pythagorean Theorem

Well, I'm going to have some Pi for desert

    Before I give a Halloween Treat, the kids have to answer a question.  I'll add What is Pythagorean Theorem to my list of math questions, with low expectation anyone will get it.

    Steve, you are a true geek, my friend.  I would neve have have thought of this.

    Thanks Mark—-I have been a Geek since I was about 6 years old. Geeks rule!

    @DaveR1234—children nowadays can get the answers on the Internet to solve a Geometric problem. I try to encourage students of all ages to be able to calculate on paper first in case the power goes out.

    We are losing the in-depth knowledge and true understanding of Mathematics as well as Electronics Engineering down to the the transistor level.

    Am very impressed with your calciation of PYthagoran Day but dissappointed that you err about something as elementary as PI day.  It actually only comes once every 100 (one Hundred) years: 3-14-15.  Next one is March 14, 2115.

    Hello Anita,

    The electronics industry (Including the IEEE) and my self included, take Pi out to only two decimal places  because that enables us to celebrate Pi Day every year, contribute some interesting and educational Pi applications yearly and enjoy the day once each year.


    In your case—you will only celebrate Pi Day once in your lifetime—how much fun can that be?

    Then there are thouse filthy Tauist heretics who celebrate in June… but they DO have beer, so I might go incognito, even though they harangue with the vilest propaganda: (or search “Vi Hart Tau”)

    I'm looking forward to next year's little-Pythagoras day 1/4 1:42, then Golden Day (1/6), followed by the Napierians' party (will they serve Pho?) (I wonder if they can overcome their schizm with the Eulerians, at least for one day).

    @GSKrasle—-I see you are a Math Geek too!
