Some of my associates pointedout that I am losing focus on "Science Today", with the serial on "A puzzle a day".
I think they are right ! Hence I am compelled to terminate this series here.
BUT, I have started a new blog for this series. "A PUZZLE A DAY"
apuzzleaday.blogspot.com
I invite you ALL to visit the new blog too. You will certainly be impressed.
The theme of the blog is :
Puzzles - for being healthy, wealthy, and happy !

Wings to tomorrow - pictorial feature.
Today, let me tell you an interesting topic. Did you see the above pictures ?
In the July 1967 issue of ScienceToday, there is an interesting article about air transportation.
It deals with a variety of aircrafts of (the then ) tomorrow.
"
WINGS TO TOMORROW
A pictorial feature on existing flying machines and a preview of air transportation of the future.
When the German Rumpler Taube flew in over Paris on August 30, 1914 with three small bombs, it looked verymuch like a bird. Today, after more than six decades man is a master of the skies. This is the story of air transportation of today and tomorrow - from the ground up.
"
The article gives a number of photographs of various air vehicles, of the past and under development. Please see some of them above.
I haven't given any explanation to the pictures. Are you interested ? Then I can ... !
This is one of the many articles- certainly very educative and informative - published in Science Today. Don't you feel these are relevant and useful even today ?
Yes they are, I believe.
P35
An old puzzle.. but continues to puzzle !
A man owns a square field. It has a house (shown square shaded) and ten trees. He offers it to his five sons on condition that they shall live together in the house and divide the land into five equal plots. Each plot must be of the same shape and to contain two trees. How could the sons divide this land?

Cases of Barrel and Switches
P 34
The Barrel : There is a barrel with no lid and some beer in it. "This barrel is more than half full," said Chuck. "No it's not," say Joe. "It's less than half full." Without any measuring implements and without removing any beer from the barrel, how can they easily determine who is correct?
P33
Switches : Three switches outside a windowless room are connected to three light bulbs inside the room. How can you determine which switch is connected to which bulb if you are only allowed to enter the room once?

Space age puzzle
Sorry, for a second time.. That's not good.... However, I pray excuse for not posting the puzzle for the last two days. My work has been in trouble, due to a travel requirement.
Here are two puzzles. Please try them.
P31
The grand prix in Space
Time : The future; Scene : The Grand Prix of the Space Age.
The course from the race is from Earth to the Moon and back. The qualifying mark is a round trip in four days for an average of a little over 5000 miles per hour. The favourite got off to a bad start and managed to average only 2500 miles per hour for the first half of the journey. However, this did not worry him unduly, as his machine had a gimmik or two up its fuselage. “ I can easily average 7500 on the return journey, and I’ll still make it, safely”, he thought.
Could he qualify ?
P32
On one of the TV quiz programmes, where they offer Rs. 64000 for the correct answer to questions like “What did Humpy Dumpy sit on ?”, the quiz master offered the question - “Why are 1963 cents worth almost $ 20 today ?”
The only numismatist on the panel was so goofed that he not only didn’t answer the question, but also the next two questions and thus lost his chance of winning the prize. In his place, what would you have said ?

Another puzzle from Henry Earnest Dudeney !
A rope is passed over a pulley. There’s a rope at one end and a monkey at the other. On both sides, the length of the rope is the same. The rope weighs 4 ounces per foot. The total age of the monkey and its mother is 4 years. The monkey weighs as many kg as its mother is years old. The monkey’s mother is twice as old as the monkey was when the monkey’s mother was half as old as the monkey will be when the monkey is three times as old as the monkey’s mother was when the monkey’s mother was three times as old as the monkey. The weight of the rope and the weight at the end was half as much again as the difference in weight between the weight of the weight and the weight and the weight of the monkey.
What was the length of the rope ?

Smoking is injurious to health
P26
Rattled by the recent Cancer scare, a friend of mine , a chain smoker, decided to giveup smoking.
“ I’ll smoke the 29 cigarettes I am left with, and never touch another”. However, old habits you know.... Our friend soon found that 3 cigarette butts and a bit of adhesive tape , intelligently put together, could produce one very smokable and hard-to-resist cigarette. How many did our friend manage to smoke before he exhausted his supply ?
"Cigarette smoking is injurious to health "

Army's gun problem
P21
This is an Army problem . But, anybody can solve it. Do it in 5 minutes.
The Army had offered a large price for the design of a rapid fire gun. Soon enough, an inventor came with a gun which when once loaded would fire 60 shots at the rate of a shot a minute. The experts put the gun to test and found that it fired 60 shots an hour. The gun was rejected, as it did not fulfill the promised condition. The inventor protested, but the experts would not relent. Were the experts right?

P 19 0769
There are three temples in a village. Each temple has an adjoining well. There is also a garden nearby. One morning the priest came to offer flowers to the three deities. He collected some flowers from the garden and dropped them in the first well ; the flowers doubled. He offered some to the first deity, then moved to the second temple and dropped the remaining flowers in the well there. The flowers trebled. He offered some to the second deity and moving to the third temple, dropped the rest in to the well. This time the flowers quadrupled. He offered all the flowers to the third deity. Each deity had received the same number of flowers and in the end the priest had no flowers left.
How many flowers did he pluck from the garden and how many did each deity receive ?

Funny clock !
P 18 191007
This happens to be a funny clock. The minute-hand moves in the regular, clock-wise direction, but the hour-hand moves in the anti-clock-wise direction. The movements are otherwise normal, i.e. the minute hand takes 60 minutes to cover 360 degrees and the hour hand takes 12 hours.
Find graphically the points of time they will meet in a 12 hour cycle, starting exactly at a time when both have coincided at 12. The timings of coincidence will be read as in any normal clock, set simultaneously at 12.

Operations Research
P 17 181007
Here is a problem for Operations Research !. In the ground floor of a four-storey house, an electrical repair-man found the ends of 11 wires in a bunch (they all looked alike) .On the top floor was the other bunch of 11. His problem: to find out which end above belonged to which end below.
He could, of course, either short-circuit the wires at either spot by twisting ends at random, or test for a closed circuit by a continuity tester. But to avoid the needless stair climbing involved, he sat down on the top floor with a pencil and paper and soon worked out the most efficient possible method of labeling the wires.
What was his method?

Reporter's problem
P15
It was the funeral of the old millionaire Sukhiram. His six direct descendants had all come to the funeral (each being a son, grandson or greatgrandson of the old man). A reporter spoke to each of them and came away with these six statements:
(i) Sukhiram was my father. Dukhiram is not my son. I have no grandsons
(ii) I am Jetharam’s uncle. Chelaram and Khusiram are brothers. Dukhiram is my uncle
(iii) I have no brothers, Khusiram is my great uncle, Sitaram is my father
(iv) I am Jayaram. Sukhiram was my grandfather. Dukhiram is Sitaram’s son
(v) I am Dukhiram, Jayaram is my uncle Sitatram is my brother
(v) Sitaram and Jayaram are brothers. Jetharam is my grandson. Khusiram is my brother.
The old man Sukhiram always spoke the truth; this virtue was kept up by the next generation. But any grandson of Sukhiram makes one false statement in three. And any great grand son makes only one true statement in three.
The preporter has to draw the family tree. Can you help him?
[Hint: A son of Sukhiram has no uncles. Having deduced whether (iii) has a brother, you can work out whether Khusiram has a son. Then find out what relation Dukhiram is to Sukhiram and which speaker he is.]

Princess and suitors
P 13
A pretty but clever princess wished to find a match for herself. She had received many proposals but had rejected them all because none of the suitors was intelligent. However, she got so tired of people coming with claims of clever deeds that she devised a test for her suitors. In a room of her palace she placed two boxes, both identical in shape and colour. In one box she kept a sword, in the other, a golden ring.
A prospective suitor could select either of these boxes. If it contained the sword he would be beheaded, but if it contained the ring. The princess would marry him. Before selecting the box, the suitor would be allowed to ask her only one question, which she would answer. The princess was known for speaking the truth only on alternate days; on other days she was a liar.
We know a suitor did marry her. What was the question that he asked?

Dog and rabbit
P12 0567 131007
There is a rectangular field with sides 80 and 60 metres. A dog at A spots a rabbit at B and starts chasing it at the same moment that the rabbit begins to run away. The rabbit runs at 20 kmph straight on to its burrow at the other end of the field at C. The dog knows he cannot catch the rabbit if he goes to B and then to C and takes a diagonal course keeping his quarry in sight and always running directly towards it. Since the dog’s speed is 25 kmph, at what point along BC will he catch the rabbit ?

Solution to Puzzles
How about posting solutions to the puzzles ? If you feel that you need the solutions too, I can post them. However, I want you to think over the puzzle and attempt to solve. Its a fact that most of these puzzles are simple, and that you may not need anyone to tell you its solutions. However, if you really need the solutions, I shall start posting them. But after two or three days ! Is that Ok ? What do you say ??
And now, Puzzle of the day !
P8 0667 091007
A man visits his friend and says, “if you will lend me the amount of money I have in my pocket, I will pay you the Rs. 10 I already owe you”. The friend obliges, and is paid the previous debt. The man then visits a second friend from whom he succeeds in borrowing an amount of money equal to that in his pocket, and pays him Rs. 10 for an already outstanding debt. This procedure he repeats on two more occasions and having paid two more outstanding debts of Rs. 10 each , leaves with nothing in his pocket. What is the total amount he now owes his four friends ?

Puzzle : The smart thief
P6 0367 071007
A thief went inside a church to steal the bell ropes. The two bell ropes passed through holes in the high boarded ceiling and he wanted to take nearly the complete lengths of the two ropes. He had only a pocket knife with him. How did he do it ? No ladders, no other gadgets, etc.. are available. You may think that he might steal one rope and slide down the other. But how did he cutoff nearly the whole lengths of both without falling ?

A puzzle a day ... For non-violence.
"The best way to defeat terrorism is through non-violence".
I think, terrorism and violence are the same. Violence, in any form, is terrorism.
"Gandhiji's principle of non-violence is relevant even today" - A press report says, quoting a VVIP. But the truth is that
Gandhiji's principle of nonviolence is relevent always, and for ever.
The best way to defeat violence (and so terrorism) is through creating positive thoughts in the mind of everyone. This is possible only through a scientific approach.
One of the methods of creating positive thoughts in the mind is through humour and concentration.
You know, puzzles are an excellant method to concentrate.
Therefore, puzzles can give you concentration, pleasure, calmness, and mental health.
So... Puzzles are a method of defeating violence (terrorism).
Shall we send "a puzzle a day" to all the terrorists? That, I am sure, would bring in world peace.

Puzzle..Raipur to Rampur !
Here is the fourth puzzle. A very simple logical one.
P4 0267 05Oct07
There is a road from Hajpur to Rampur. Virpur is at just half the way between Hajpur and Rampur. Raipur is just as far from Hajpur as it is from Virpur and Virpur is as far from Raipur as it is from Rampur. If it is 20 KM from Hajpur to Raipur, how far is Raipur from Rampur ?
All the best !

Puzzle of the day
Here is the third one. A very simple mathematical puzzle.
P3 1266 04Oct07
Ajith, a villager, went to his neighbor Kasim, to borrow 4 litres of kerosene. He took a container with him. Kasim had a stock of a full bottle of 8 litres of kerosene. He agreed to share half of what he had. But they didn’t know how to share. Kasim had two empty bottles of 5 litres and 3 litres each respectively, with him. There were no other measures or other bottles, but had to divide the oil exactly into two equal parts. How could they do it ?

Puzzles : Solution to Terrorism and Violence
You now know that "A puzzle a day" series is ON. But have you thought about the significance of starting the puzzle on October 2 ? As you rightly guessed it, its "Gandhi Jayanthi" , a day for peace and non-violence in the world. Today, I think violence, in its all forms, do trouble all of us, the world over.
The only solution to this problem is teaching and practice of non-violence, the Gandhian principle.
Our first puzzle is intentionally chosen. This logical problem ( I hope you had read and tried it !! ) is very meaningful (not alone interesting).
The missionary, in the hands of the cruel tribal people, is really in danger, for sure. He will be killed in one of the two methods. But, the Chieftain,
to show his smartness (or clever ?) puts a question to him.
He didn't mean to offer an escape route.
Read the question, it's very clear. The cruel Chieftain must be laughing.
But, the Missionary, tackling the question in a very intelligent manner, escaped. His answer was such that, he could not be killed.
The Chieftain had no other way, but to let the Missionary free !
See, this is an excellant case of how intelligence outsmarted the cruelty (terrorism or violence).
The morale of the story is that, intelligence applied well (that's godly! ) can counteract all the evils of the world.
Let's all act intelligently well (that's also Gandhism) to make this world a heaven. A world without violence.
That's the answer to the puzzle of terrorism and violence.

Here is the second puzzle ...
An explorer decided to go hunting one day into the thick forests. He started from his camp, walked 15 KM due South. But he could not find anything to hunt. He turned right and walked 15 KM due West. The lucky man could find a bear, and shot it. Slinging the heavy beast on his shoulders, the man started for his camp. After walking 15 Km due north, he reached his camp. What was the color of the bear ?

A PUZZLE A DAY
“A puzzle a day“
Some of my students, last day, suggested me to post PUZZLES here. I thank them for a wonderful suggestion. Yeah, I decided to start posting puzzles here. Puzzles, like jokes, are certainly a pill for a healthy mind. Puzzles are a good pastime too. Therefore, I am very happy to initiate a new series here !!!
“A puzzle a day“
My objective of this series is to give YOU, all visitors to this place, HAPPINESS ! Happiness by keeping engaged for sometime; thinking ( and so exercising your brain) ; and deriving pleasure out of the results.
Puzzles can keep you healthy, since you are exercising your brain (intellect) and your mind. Puzzles are stress busters too ! A healthy mind in a healthy body only can make you really healthy.
Puzzles can make you wealthy, as they are good resources for all intellectual activities. They help you take good decisions, may be good business decisions too ! Good decisions make you wealthy !
Puzzles make you happy, as they are like jokes. They are stress relievers; they make you smile, laugh, and gets you the thrill of achievement.
So, I think, “a puzzle a day “ programme is worth in every dimension. Let me reframe my objective :
Let everyone say : A puzzle a day keeps me healthy wealthy and happy !
But what’s YOUR role ? I request ALL to post the answers and discussions (as comments) here. I’ll keep a track of who answers first, and award points. Who knows, someday we all may be able to institute a prize for the top scorer !
OK ? Let’s start right here. Oh before that , I must tell you that what I present here are based on puzzles published by “ScienceToday”. Thanks ST !!
The first one in the series :

P1.
A missionary, who was touring an island, was captured by the primitives of that island. An elaborate ceremony was on, headed by the Chief, and was to be concluded by killing the slave. The Chieftain came, and told the missionary :
“You have a choice as to the manner of your death. You can make a statement. If you are telling the truth you will be roasted. If it’s a lie, you will be cut to pieces.”
The missionary made a statement, and did live to tell this tale. What was his statement ?

Post your answer here.

History of Science & Technology
If someone says " My hobby is Philately", I understand. He is crazy about stamps ( and that too old stamps and coins). But what if I tell you that my hobby is "collecting old books and magazines" ?
What do you call this hobby ? ...........y ??
Science Today is about Science and Technology; history of it. If you read the issues (1966 to 1991), you will get a feel of how Technology was during those decades, and also a view on how it was earlier. That's not the end; you can study as to how and what those guys predicted developments in S&T. Make a comparison of those predictions and today's status !
ST have been presenting all its contents in simple terms ( mostly). They are easy to read and digest materials.

"Science Today" is not Science yesterday !
“SCIENCE TODAY” is not about 'Science yesterday'. It certainly is about Science today too.
As I had mentioned earlier, ST deals with the then latest of Science and Technology (1966-1991).
After this many years, some of you may feel, the articles are irrelevant or obsolete !! But that’s not the case. All contents of ST are relevant even today. Not only that; some of the articles are so interesting (sweet ! ) and nostalgic !
It is interesting to go through the articles; how the technology was those days, compared to those today. This itself is an excellent study ; How the Science and Technology grew over the last 4 decades.
For the youth today, ST is an excellent media to understand how S&T was for their parents, at their youth. Is it not exciting ? !
ST has been presenting the basic science and technology in a very simple format, in language and presentation. Well structured (edited), the articles had all necessary illustrations, with photographs as well.
ST definitely has the reputation of being simple and digestible to the common man. The data are accurate, and authoritative.
“SCIENCE TODAY” is not science yesterday ! Its truly relevant today too.
“ST” magazine, per say, may be history. But its contents are certainly current, with a historical flavour ! My attempt here is to relive “Science Today” !

"Science Today" : an invaluable treasure of knowledge on Science and Technology.
Hi all,
I had given a hint to you that this is a complete collection of the magazine "SCIENCE TODAY" ( from Times of India group, Bombay) published during 1966 to 1991. Now I am re-doing a verification of the status of the collection ( a couple of issues are missing it looks !!). But, this is not just a collection of old issues of a magazine. This is a unique asset/knowledge resource created over time, taken care with effort, money, and dedication.
Now, this treasure is available to all of you. My objective is to share this unique resource with all those needy person.
Whoever and wherever you are, this is available to you. But how ?
1. You tell me a topic; I can search for this item in ST, and let you know.
2. You ask for a photocopy of a page, an article, an issue in full, OR even the whole collection.
3. I can send you the copies through courier.
4. I can mail their images (taken with a digital camera) to you.
{ But, kindly note that searching, copying , photographing, courier etc.. involves effort, time, and cost. So, you may have to bear its cost - a very nominal one.
However, one or two pages, as an image, can be emailed to you absolutely free. }
I had mentioned about the photos of some of the cover pages, for you to see. But, the photos could not be uploaded. It always gives me an error messages. Sorry for that. Today I shall try with a low resolution image .

SCIENCE TODAY - Entertaining..Exciting...Instructive..
Right ! Really entertaining, with many regular articles, experiments, games, etc.. And educative as well.
It's exciting ! Even today, the articles are so exciting (even the cartoons ) . All the articles are simple, presented (written and drawn) in a simple, but serious style. Even children will enjoy reading and learning.
True, it's instructive ! All the items (put under various titles / departments) are relevant even today. You learn a lot by reading them. Remember, the contents are not just "old' or obsolete. They are all relevant and current even now. Except that some of them has the historial value too.
I shall put a few of the articles here, for you to read, learn, and enjoy. wait for those posts.
ST is an excellant reference library of Science and Technology. It is a "paalazhy" of information, and hence a very valuable knowledge resource.
ST can thus help you all ...Teachers, Students, researchers, and (as I told you last time), anyone
with an interest in Science and Technology.
I offer my services to get you the material from the ST issues (complete collection available with me @* ).
In the meanwhile, please have a look at some of the cover pages of ScienceToady !
Anyone listening ???

"Second Life" of Science Today
Hi all,
ST was born in August 1966. Grown, at the age of 22, ST had a rebirth. ST was renamed as :
The new name was from April 1988. It would be an interesting research into the life of ST, in its second life. I'll someother time post a study
(maybe, in a management angle !)

Welcome to "Science Today".
Awake and Arise all Scientific Communities .... !
I welcome you all to the wonderful and exciting world of a knowledge resource (treasure) : "Science Today". Scientists, Technologists, Researchers, Managers, Teachers, Students,
and all those interested in Science and Technology ... all will find something useful here.
Before I proceed...
Most of you may remember (be aware of) the Indian Science&Technology magazine titled "Science Today" ( a Times of India publication). Started publication in July 1966,
ScienceToday (hereafter called "ST" ), was very popular, and served the purpose of
educating (and making aware of ) Science and Technology to the millions of India.
However, younger generation may not be aware of this fantastic treasure of knowledge.
ScienceToday, as ToI says is "For Everyman".
True in all respects ; its for Everyone !
If anyone feels that the resources in ST are obsolete today (who wants 1966's data and knowledge ? ! ? !), then you are not right. What ST gives is precious ,
rare, and very very very useful. And interesting too !
I have the complete collection of this precious knowledge resource. Now, I think I can
share the ST resources with anyone in need. I shall post more details, in a day's time.
Are you interested ? Please post your comments and views.
Prasanna.
