How speakers work

Jacob O’Neal makes animated infographics on his site, Animagraffs, that show how things work. A recent one that caught my attention shows how loud speakers work.

Below is an example of part of the Animagraffs on speakers, but you need to see the full sequence to appreciate how he breaks down the complex technical processes into a visual learning experience.

There are only about ten of these Animagraffs on the site, which isn’t surprising because of how much research and work they take to produce. Other interesting ones are about how a car engine works, what happens inside a jet engine,  how to Moonwalk (the dance not the space activity), and the biology of tarantulas (not for the faint of heart).

Population.io

Well, this is depressing. I used to think I was one of the young ones, but it turn out I’m older than 51% of the world’s population, according to data from Population.io. I still have a ways to go before I’m older than half the people in the United States, and I live in Florida, so I’ve got that going for me too.

Population.io is a data visualization project that takes demographic and population data from a variety of sources to present personalized graphs. Here’s how the project’s creators describe it.

Population.io aims to make demography – the study of human populations – accessible to a wider audience. We believe that demographic data can play an important role in understanding the social and economic developments of our time. Our hope is that people from all walks of life, in all ages and across all countries will explore a new perspective of their own life and find their own place in the world of today and tomorrow.

Here are a couple of other interesting factoids I learned about my age in relation to the global population:

  • On May 24, 2017, I’ll be the 4 billionth person on the planet
  • I’m older than 40% of the US population
  • I share a birthday with 319, 574 other people (13,315 of whom were born during the same hour)
  • My estimated death day is August 2, 2067 (That date is marked in my calendar thanks to the site’s handy iCal download–morbid I know)

It seems I still have many years ahead of me–52.7 years–based on the average life expectancy of men in the US.

Jurassic World is open

The trailer for the new Jurassic Park movie came out yesterday. It looks like a promising summer blockbuster. While there is little chance it will live up to magic of the original, the previous sequels left a low enough bar for this one to easily surpass.

Even without a Michael Crichton novel to draw from, the writers of the movie came up with a great premise: despite the previous disasters on the island, the park is completed and opened to the public. It features various dinosaur attractions that follow the familiar motifs of Disney Land and Sea World. However, things go wrong when a genetic hybrid dinosaur escapes. Tim Siedell has high hopes for the genetically modified monster.

The ending of the trailer features a haunting version of John Williams original theme music played one piano key at a time. I can’t wait for June 12.
