285 million people in this world are visually impaired in some way. 90% of the them live in developing countries. Unfortunately, today’s prolific and glamorous technological revolution focuses little towards these group of people with limited purchasing ability and varying needs. Being a citizen of a developing country and irresistibly fascinated by the increasing capabilities of computers, I always wondered — how significant is the contribution of science and technology to the lives of these people? I am interested in using computing technology to make positive impact on humans’ lives. I want my work to enlighten the underprivileged ones with knowledge and opportunity.

I am interested to apply Machine Learning in Human Computer Interaction (HCI), Affective Computing and Accessibility. I work with Dr. M. Ehsan Hoque in ROCHCI to push the boundaries of science and to touch the lives of people.

My name is Md. Iftekhar Tanveer and I am a graduate student of Computer Science at University of Rochester.

# Positive Infinity and Negative Infinity

Recently, I watched a BBC documentary named “Horizon: Infinity” that illustrates several concepts of infinity. These are some thoughts that have been perplexing humans for a really long time.

The most common facts about infinity are usually expressed using a concept of an infinitely large hotel – which has infinitely many rooms. Even when that hotel is full, it is possible to make room for 1, N or infinitely many new customers. How? If you need N rooms, tell all the existing customers to shift in room number i+N, where i is their current room number. You’ll get N free rooms (1 to N). If you need infinite rooms? Tell the existing customers to shift in room 2i. You’ll get all the odd rooms free. This is just an illustration of the fact that $\infty + N = \infty$ and $\infty + \infty = \infty$. It is also possible to show that some infinity is larger than other infinity (e.g. set of real numbers is larger than the set of integer number). So, there are differences among infinities.
