Mathemajics & Memory

The speed, capacity and efficiency of our memory depend, to a degree, on our mental make-up and the knowledge of divergent fields. Man's mind once stretched by new exercises as the ones below never goes back to its original dimensions.

SUM OF ALL DIGITS UPTO 10

1 to 10 i.e. 1+2+3+4+5+6+7+8+9+10

Multiply last number by a number next to it and divide by 2 : i.e. (10x11) /2 = 55

For 1 to 20, Add 100 to 55 , for 21 to 30, add 200 to 55, and like wise >>>>

11 to 20 >> 155

21 to 30 >> 255

31 to 40 >> 355 and carry on likewise.

==================================

Multiplication of 2 nos whose diff is 2. >>> Say 14 x 16

1. Take Middle No. >>> 15

2. Squre it >>>> 225

3. Minus 1 >>>>> 224

4. Answer is 224.

==================================

Multiplication of two 2 digit numbers whose 'ten' digits are same and 'unit' digits' sum is 10. Like 47 x 43 >>>>> 4 same 7+3 =10.

--------------------

1. Multiply Ten Digit Number by next whole no >>> 4 x 5 = 20

2. Multiply Unit Digit Nos together >>> 7 x 3 = 21

3. Answer is 2021

Peace Invades

A king once offered a prize to the artist who would paint the best picture of peace. Many artists tried. The king looked at all the pictures. There were only two from the many which he really liked. But the choice was difficult.

One picture was of a calm lake, a perfect mirror for towering mountains all around it. Overhead was a blue sky with fluffy white clouds. A perfect picture of peace.

The other picture had mountains too but rugged and bare. Above was an angry sky with lightening and thunder and it poured furiously! Down the mountain side, a foaming waterfall hammered on rocks below.

The king had a close look at both the pictures. He chose the second to the surprise of all.

The close quick look saw behind the intimidating waterfall a tiny bush growing in a crack in the rock. In the bush, a mother bird had built her nest where she sat in perfect peace nursing the babies.

The King explained his choice, "Peace does not mean just a quiet place where there is no noise, danger or hard work. Peace found by the bush and the bird in the depth of their hearts in the midst of all that lightening and thunder and the rock-and-roll water fall has also true meaning of Peace.

Peace does not dwell in the outward things but within the soul. We may preserve it in the midst of bitterest pain if our will remain firm and submissive. Peace in this life springs from acquiescence, not in an exemption from suffering…. Fenelon

Reduce the Load on Knees

To keep our mobility intact beyond Sixties into our Nineties, we need to start building up quadriceps (Front of thigh) and hamstring muscles (Back of thigh) right from childhood. To keep them in trim with age, we need to do the following exercises regularly within the framework of staying power and comfort levels.

Weak Inflexible Sluggish Quadriceps and Hamstring Muscles will increase the load on Knees for worse.

SQUATTING for QUADRICEPS AND HAMSTRING MUSCLES

1) Stand upright with feet slightly apart and hands stretched upwards.

2) With straight back in line with head, slowly bend knees (not waist) controlling movement down within comfort level.

3) Ensure that knees follow the same line as toes.

4) Return smoothly to starting position with ease.

5) Breathe in as you go down, out as you come up.

6) Graduate slowly to 5-10-15… ups and downs.

7) Graduate slowly keeping feet raised on toes both ways.

FOR HAMSTRING MUSCLES ONLY

1) Lie flat on your back with stretched legs.

2) Bend right knee with bottom of foot flat on the floor.

3) Raise left leg straight in air supported by hands if need be.

4) Softly straighten left leg from knee.

5) Feel the hamstring stretch within comfort limit.

6) Repeat exchanging legs.

Quick Beer on a Full Belly

The class was amazed to see on the Lecturer's desk a bag of sand, a bag of pebbles, some big rocks and a bucket. It was time for a pre-exam lecture on time management. He beacons an undergraduate to come on the platform and fill up the bucket.

A thoughtless novice starts with the sand, then the pebbles, then wastes lot of time pushing in the rocks, which not all fit in the bucket and makes a mess.

"Isn't that poor time and thought management" shrills the lecturer, "If you'd have put the rocks first, then the pebbles, then the sand, all three would have fit to the full. This is much like time management, in that by completing your biggest tasks first, you leave room to complete your medium tasks, then your smaller ones in given time. By getting lost into your smallest tasks first, you spend so much time on them, you leave yourself unable to complete either medium or large tasks satisfactorily.

And the lecturer re-fills the bucket, big rocks first, then pebbles, then sand, shaking the bucket between each so that everything fits. And heaves a sigh of anticipation of thunderous clapping.

"But Sir," Walks in one student, slouched at the back of the class, "you've forgotten one thing…..."

At which the student approaches the bucket, produces a can of lager, opens it, pours into the bucket and quips with a smile, "No matter, Sir, how much full, your bucket or belly is, there's always time, space and thought for a quick beer."

A Health Officer drives into a village to check what precautions the villagers are taking for pure drinking water.

The Village Head assures the Bureaucrat that they chlorinate the village Pond, discourage activities like swimming, washing in the pond, collect water from the pond in clean utensils and boil water. Even then for the sake of safety, they drink beer only!
