What Really Matters at the End of Life | BJ Miller | TED Talks

At the end of our lives, what do we most wish for? For many, it’s simply comfort, respect, love. BJ Miller is a palliative care physician who thinks deeply about how to create a dignified, graceful end of life for his patients. Take the time to savor this moving talk, which asks big questions about how we think on death and honor life.

ONE PERCENT 2015 - A day of mathematics for students of class XI and XII

Dear friends,
A famous mathematical institute called, The Institute of Mathematical Sciences is organishing a Quiz competition in Mathematics on November 20, 2015(Friday).

Do not miss this Opportunity,

ONE PERCENT 2015

A day of mathematics for students of class XI and XII

In this programme they have planned,

• This is the 2015 edition of the institute's outreach program for school students.

• Come and interact with professional mathematicians working at the cutting edge of research.

• Let them share with you the excitement of mathematical discovery.

• Participate in our Quiz and win a prize.

• Return inspired to learn more.

Registration

To nominate students for participation, the head (or other representative) of the school should e-mail to  maths.outreach.imsc@gmail.com with:

• Name of the school
• Contact details (e-mail and postal address, telephone number) of the school
• Names of students being sent (from classes XI and XII; at most five students totally)
• Name of the accompanying teacher/escort (optional)

Nominations will be accepted on a first-come-first-served basis, so hurry! 
A list of schools whose registration has been accepted is here (updated daily on working days).

My school is not participating. Can I still attend?

We prefer students to come through their schools. But we will consider requests from individual students, with preference being given to those from schools that are not participating. Such a student may send an email to maths.outreach.imsc@gmail.com with the following information: name of the student, name of the school, brief writeup (not exceeding 100 words) about why he/she is interested in participating. Names of the selected students will be posted here.

My school has not received an invitation. How can we participate?

Please consider yourself invited and register according to the instructions above.

Faster than a calculator

Benjamin makes numbers dance. In his day job, he's a professor of mathematics at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage to perform high-speed mental calculations, memorisations and other astounding mathematic stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

TEDxOxford is organised by University of Oxford students, aiming to bring together the young minds of tomorrow's world with the movers and shakers of today. TEDxOxford is kindly sponsored by Neptune Investment Management - http://www.neptunefunds.com

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Are Paradoxes really necessary?

What is a PARADOX?
A paradox is a self-contradictory statement, which can only be true if it is false, and vice versa. It is a claim that two apparently contradictory statements are true.

Paradoxes can be used anywhere. They are used in literature, philosophy, Science and paradoxes exist even in Mathematics. What is the need of using a paradox? If the statements are self-contradictory, why must we even spend so much time on learning them. Paradoxes, though are self-contradictory, they help us reveal the flaws either in the way it is stated or in the logics used to come to a conclusion based on those statements.

You have learnt about statements in mathematics or elsewhere. A statement is a kind of expression of something that is either TRUE or FALSE and cannot be both or neither. Consider this statement here,

p: This statement p is false.

Here, the statement says "statement p is false". So if the statement p is false then the implication made by it will be false and hence the statement cannot be false. So it must be true. But, if the statement is true, then what it says must be true which again brings us back to beginning and implies that "statement p is false". A bit confusing isn't it?? Well, don't panic, you are not alone. If you're seeing this for the first time it is normal to get confused. Another set of false statements can be as follows,

The statement below is true.

The statement above is false.

Here again, if the first statement is true then what it says must also be true and it says that the second statement is true. But, the latter statement states that the former statement is false and hence what the former states must also be false, which brings us back to the beginning loop of our deduction. No matter whether you consider the first statement to be true or the second statement, you will end up concluding nothing. 

But why do we require such paradoxes in Mathematics? 

It is because, they point out the flaws in definitions which intuitively seem to be true, and have caused axioms of mathematics and logic to be re-examined. One such famous, yet fundamental, is the Russell's Paradox which is also known as Russell's Antinomy, discovered by Bertrand Russell in 1901. Russell's Paradox  questions whether "set of all sets that contain themselves" would contain itself.

Let R be the set of all sets that are not members of themselves. If R is not a member of itself, then its definition dictates that it must contain itself, and if it contains itself, then it contradicts its own definition as the set of all sets that are not members of themselves. This contradiction is Russell's Paradox.

There are many more paradoxes, some of which related to mathematics and many others which do not. Few that requires logic to understand and many others that do not need any special knowledge. This post today is just to ignite a spark of interest in the fresh minds to know more about Mathematics.

Comment your opinions and suggestions in the comment box if you need more clarification or whether I must simplify the complexity of language used in this post. I suggest you to discuss with your teachers and fellow classmates about these and learn many more paradoxes that exist, out there in the vast world of logic, assumptions, and whatsoever.

Following are few links to few other paradoxes you might want to take a look at:
1. The barber paradox
2. The paradox of Theseus' Ship
3. Zeno's paradox
4. The paradox of heap
5. The grandfather paradox
