Math Teacher Breaks Pull Up World Record

Kyle Gurkovich, a middle school math teacher from New Jersey broke the pull up world record. He made 4182 pull ups in 24 hours breaking the previous record made by a Navy Seal.

Gurkovich came up with the idea of pull ups in order o raise funds for cancer research. He was able to raise $8060 which he donated to Memorial Sloan Kettering Cancer in New York City.

Guinness recognized Gurkovich’s record.

Gurkovich is set to break his own record this November.

How cool is that huh?

How to Multiply Using Lines and Dots

One of the great things about mathematics is that sometimes, you find mathematical concepts in places that you don’t expect them to be. There are also concepts or representations that seem not connected to mathematics, but you will realize that it is indeed mathematics.

In the video below, observe how to multiply using lines and their intersections.

Don’t just watch  the video for the sake of entertainment. I encourage you to think about it.

Why does the method work?

Can you think of other concepts that is similar to the intersection of lines?

Is there a similar representation or idea that is also connected to this representation?

In the next post, we will try to answer the questions above, so keep posted.

Hans Rosling: Stats That Reshape Your World View

More than three years, ago I have introduced to you an amazing software called Gapminder which enables users to visualize trends through animated bubble charts.

Well, I don’t think I need to explain more. Watch Professor Hans Rosling, co-founder of Gapminder Foundation use Gapminder and be amazed about how statistics can explain what is happening in our world.  Continue reading
