What is economics ?

One day a tourist comes to the only hotel in a debt ridden town in Kenya. He lays a 100 dollar note on the table & goes to inspect the rooms. Hotel owner takes the note & rushes to pay his debt to the butcher. Butcher runs to pay the pig farmer. Pig farmer runs to pay the feed supplier. Supplier runs to pay the prostitute, who in these hard times gave her services on credit. Prostitute then runs to pay off her debt to the hotel owner for the rooms she rented for her clients. Hotel owner then lays the 100 dollar note back on the counter. The tourist comes down, takes his money & leaves as he did not like the rooms.

No one earned anything. But the town is now without debt & looks to the future with a lot of optimism.

Anchor Effect – How does Anchor effect change price dramatically ?

Anchor Effect – Where you plant a number in someone’s mind and change their way of looking at things.

Simple example is the above image where you sell something at $199, by just showing a big number to someone like $500 , this $500 has just a simple role of planting that big number in buyers mind and nothing else.

Lets see another example where you want DONATION Continue reading

Why do we fall asleep during lectures?

John Medina, in his book Brain Rules, introduces data that forms the following graph:

h

The data shows that student attention level takes a dive, approximately 10 minutes into a lesson.  This is a natural occurrence (and I believe the reason YouTube videos were initially limited to <9 minutes), but can be dealt with by a good instructor.  The problem is most instructors (particularly at the university level) know next to nothing about the learning process and instructional theory.  A good instructor will introduce variation into a lesson every 10 minutes to regain the students’ attention (as depicted in the below graph).

g

This variation can be accomplished in many ways – from inserting a student activity to asking questions or otherwise soliciting involvement from the students to changing the delivery style or mechanism.

The problem is that so many instructors see instructing as a one-way communication.  If a student is not contributing to the communication, they lose focus and many literally go to sleep.

There are other triggers for sleeping during lessons, such as eating a large meal immediately before the lesson, poor ventilation in the classroom, and tired students.

What are some good manners a person should possess?

I guess now a days we have forgotten even the most basic manners which were once natural to us.Blame it on the technology, exhibitionism or the nuclear family system it is indeed a pity that we can’t bring ourselves to behave like human beings without a reminder.
I found these pictures doing rounds on the internet a few days back about the changing manners we should know.So let the pictures do the talking.

15. If you compress the time from the Big Bang to the present in a single year then:

January 1st -The Big Bang occurred.

January 10th -The first Star was born.

January 13th – First small galaxy.

March 15th – The Milky way formed, but not the Sun.

August 31st – The Sun was born (that’s approximately 4.5 billion years ago)

The Earth was born from a disk of gas and dust orbiting the new born Sun. Repeated collisions produced a glowing ball. The Earth was quite unstable in the beginning. But,

Sept 21st – Life began (3.5 billion years ago)

November 9th – Life was breathing, moving, eating. We owe a lot to those early microbes. They invented sexual reproduction.

December 17th – Life came from water to land.

December 28th – The first flower blossomed.

6:24 am, December 30th – An asteroid hit earth and wiped out dinosaurs that could endanger the survival of homo sapiens on earth (60 million years ago)

For the first time in the history of the universe the conditions were just good enough for humans.

11:59:46 pm December 31st – All recorded history occupies these last 14 seconds.

We learned how to cultivate crops, tame animals, astronomy, mathematics, and painting. About 13 seconds ago, we invented writing.

Moses was born 7 seconds ago.

Buddha – 6 seconds ago.

Jesus – 5 seconds ago.

Muhammad – 3 seconds ago.

A second ago we discovered that Earth is not the centre of the universe
And just when that second was about to finish, we reached the Moon.

Every person you have ever heard of, met, loved, hated, kissed, and reproduced with, lives in those 14 seconds.

What are some interesting facts about Highways in India?

Types of Milestones on the basis of road

How do you know if a highway, you are travelling on, is a national highway, a state highway or a district/city road.
