How to Memorise Binary Numbers?

Squadron Leader Jayasimha, President World Memory Sports Council for India& Multiple Guinness World Record Holder explains the Second Memory Discipline of Memorising Binary Numbers and the scoring pattern.

Since the Indian Memory Championship is going to be conducted on 15th October 2017 in Hyderabad, all the Memory athletes should be capable enough to compete in all disciplines to win the Championship. There will be a special training session in September in Hyderabad. Till that time, kindly go through and familiarise yourself with memorising binary numbers.

EVENT RULES –

Memorising Binary Numbers by Squadron Leader Jayasimha

 

Event 2 Memorising Binary Numbers
Aim To commit to memory as many Binary digits (101101 etc) as possible and recall them perfectly.
Time to Memorise 5 Minutes
Time to Recall 10 Minutes
Question Paper
  1. Computer generated numbers are presented in rows of 30 digits with 25 rows per page. (600 digits maximum)
Answer Paper
  1. Contestants must write their recalled numbers in rows of 30 digits.
  2. Contestants may use the answer sheets provided or their own (as long as it has been cleared by the adjudicator before recall commences).
  3. It must be clear how the rows presented on the answer paper relate to the rows on the question paper (missing rows must be clearly indicated).
Scoring
  1. 30 points are awarded for every complete row that is correctly recalled in order.
  2. For every complete row of 30 that has a single mistake in it (this includes a missing digit), 15 points are awarded.
  3. For every complete row of 30 that has two or more mistakes (including missing digits) 0 points are awarded for that row.
  4. For the last row only – If the last row is incomplete (Eg, only the first 19 numbers have been written down) and all of the digits are correct, then the points awarded will equal the number of digits recalled (19 in this example).
  5. If the last row is incomplete and there is a single mistake (this includes a missing digit) then the points awarded will equal half the number of digits recalled. (For an odd number of digits the fraction is rounded up, Eg, 19 the score would be 19/2 rounded up equals 10)
  6. The winner of the event is the contestant with the highest score.

 

I will explain the phonetic method of memorising normal numbers later in the next discipline. Here, binary numbers means 0101010101110001010101101010100011001101010001010101010000000.

We have to memorise them, the idea is only these two numbers 0 and 1 are coming again and again. Only way we can memorise these binary numbers is to convert them into normal numbers.

If you look at the pattern, you will find that basically we have the following 8 patterns :

000

001

010

011

100

101

110

111

What we are going to do is to give one normal number to each digit here :

000 = 0, 001=1, 010=2, 011=3, 100=4, 101=5, 110=6, 111=7

How do we derive these numbers is very simple

Units place value is 1, tens place value is 2, hundreds place value is 4

Like you have to find the value of 000, 0x4+0x2+0x1 = 0

001 will become 0x4+0x2+1×1 = 1

010 will become 0x4+1×2+0x1 = 2

011 will become 0x4+1×2+1×1 = 3

100 will become 1×4+0x2+0x1 = 4

101 will become 1×4+0x2+1×1 = 5

110 will become 1×4+1×2+0x1 = 6

111 will become 1×4+1×2+1×1 = 7

These are the only combinations we are going to get.

Now let us take the number give above 0101010101110001010101101010100011001101010001010101010000000. Here, we are going to convert every 3 digits into one normal digit, see below

010 =2, 101=5, 010=2, 111=7, 000=0, 101=5, 010=2, 110=6, 101=5, 010=2, 001=1, 100=4, 110=6, 101=5, 000=0, 101=5, 010=2, 101=5, 000= 0, 000=0.

Let us write the numbers 25270526521465052500

So have converted them into normal numbers.

Next what we are going to do is use phonetic method and convert these normal numbers into pictures.

Then we will use journey method or loci method or visualisation method to remember these pictures.

To recall them, we have to re-convert the pictures into normal numbers, from there to binary numbers.

This process seems to be little difficult, but once you start practicing, this become very easy. As you know, that I have made two Guinness World Records in memorising Binary numbers, you too can do with little bit practice.

 

For memorising normal numbers, I will explain that in the next discipline.

Till that time keep practicing, if still in doubt contact Squadron Leader Jayasimha on 9866018989.

Hope, you have filled up the application form for the National Memory Championship 2017, if you haven’t done so far, do it immediately.
