Memory Power by Dhaval Bhatia

Introduction

• The human mind always remembers whatever is special, different, unusual or extraordinary. It forgets whatever is trivial, ordinary and routine
• YES, I KNOW A NUMBER
• pi value: 3.1416 !! => mnemonics.
• The human mind always remembers whatever is special, different, unusual or extraordinary. It forgets whatever is trivial, ordinary and routine
• Students giving exams are required to memorize many answers from their textbooks. In such situations, the best method is the Link Method 
• repetition is undoubtedly a fool-proof technique. It works because every time you recite or revise something, you are creating a pathway in your mind. The more you revise, the deeper the track becomes, giving you more time before you start forgetting again. A prolonged time gap between two consecutive revisions is a sure-shot recipe for forgetting

Zeller's Rule => Calculate calendar of any year.

• F = k + [(13 x m-1)/5] + D + [D/4] + [C/4] - 2 x C,
• k: date
• m: month number
• D: Last two digits of the year
• C: The first two digits of the century
• Rules
• In Zeller’s Rule, the year begins with March and ends in February. Therefore, the month number for March is 1, April is 2, May is 3 and so on up to January, which is 11 and February, which is 12.
• January and February are counted as the 11th and 12th months of the previous year. Therefore, if we are calculating the day corresponding to any date in January 2026, the notation will be (month = 11 and year = 25) instead of (month = 1 and year = 26).
• While calculating, we do not consider numbers after the decimal point.
• Once we have found the answer, we divide it by 7 and take the remainder. As before, a remainder of 0 corresponds to Sunday; a remainder of 1 corresponds to Monday; remainder 2 corresponds to Tuesday and so on. 
• If the remainder is negative, then we add 7 to it to determine the corresponding day.
• Example
• Find the day corresponding to June 26, 1983.
• Here, k is 26, m is 4, D is 83, and C is 19.
• F = k + [(13 x m -1)/5] + D + [D/4] + [C/4] - 2 x C
•    = 26 + [(13 x 4 - 1)/5] + 83 + [83/4] + [19/4] - 2 x 19
•    = 26 + [51/5] + 83 + [20.75] + [4.75] – 38
•    = 26 + 10 + 83 + 20 + 4 - 38 (we drop the digits after the decimal)
•    = 105
• When 105 is divided by 7, the remainder is 0. Thus, the day is a Sunday. Thus, June 26, 1983 was a Sunday.

List System

• We shall make two lists – permanent lists and temporary lists. Permanent lists always remain fixed; they never change. Temporary lists change all the time.
• for eg: permanent list is list of family members of you in age order, then following can be used to memorise that number of random objects for short times
• In this system, we will associate each element of our permanent list with each element of the temporary list and form ten easy visuals.
• Imagine a typical situation in a student’s life. You have an exam tomorrow, for which you have to remember 15–20 answers. You just want to remember the main points of each answer, because you know if you remember the main points, you can easily elaborate on them and write the complete answer. However, there are so many chapters and so many answers. So, what do you do? One permanent list will not be sufficient for this. You will have to make many permanent lists. You can choose lists based on different areas of interest and people, such as sports, movies, politics, friends, neighbours, relatives, or any other list that you like.

• Eg:

• Visualize your first friend (name: __________ ) has 2,000 children in his family! He lives in an overpopulated house. See your friend with the 2,000 children surrounding him.
• Your second friend has suddenly become poor and he is now begging on the streets in tattered clothes.
• Your third friend is illiterate. Visualize him reading a book upside-down.
• Your fourth friend is unemployed and desperately scanning the newspapers for job vacancies.
• Your fifth friend is driving a golden Audi, but is stuck in a traffic jam and is cursing everyone loudly.
• Your sixth friend is standing on the beach. Suddenly, a tsunami wave (natural calamity) erupts and engulfs him completely.
• Your seventh friend is corrupt. Visualize him hiding money in his shirt, pants, shoes and cap.
• Your eighth friend has to be linked with technological waste. Visualize he has 100 old mobile phones in his garbage can.
• Your ninth friend has to be linked with pollution. Visualize he has a chimney on his head, which is emitting smoke.
• Your tenth friend is the victim of a terrorist attack. Someone has shot him, the bullet has hit him in the leg and it is bleeding.

Note

• A hafeez, according to Islam, is a person who has memorized the entire Holy Quran, the religious book of the Muslims. You can quote any sentence from the Holy Quran and they will tell you the exact chapter number and verse number from which that line is taken.

• All contacts in my SIM card will be regularly backed up. If needed, I will maintain a physical diary to jot down the important numbers.
• Every important file on my laptop has to have an external backup on a hard drive or on a cloud storage system. I will always keep a pen drive handy and save my work on it after every work session.
• All documents, bills, invoices and visiting cards will be kept in their respective files the very day I receive them. (If I procrastinate, the papers will keep piling up, and it will take hours to look for a single sheet of paper.)
• All credit card dues will be paid on the same day I receive the statement from my bank. All mobile, electricity and other household bills will be auto debited from my bank account.
• All appointments will be noted in my cell phone and an alarm reminder will be set for two hours earlier (so that I can get ready and reach the meeting on time).
• All birthdays, anniversaries and other events pertaining to my family members and friends will be stored in a Calendar app on my iPad (even if I were to forget an event, the Calendar app would buzz a notification and remind me).
• All house keys, office keys and car keys will be put only in the key box and nowhere else.
• All property documents and other crucial documents will be put in my bank locker. I will also maintain a password sheet where I will write all my email IDs, internet passwords, bank passwords and frequent flyer numbers and store them in my bank locker, because it is the safest place I know.
• A scanned copy of my passport, photo and driving license are to be saved in an email which will lie untouched in my inbox. Perchance If I have to produce an identity proof or document somewhere and I am not carrying it, I can easily log on to the nearest Internet device and retrieve them.
• Every email or missed call must be responded to within 24 hours.
