So...Just How Friggin' Old Am I?

Another August 7th is now history.

And with its passing, I've observed another anniversary of my earthbound existence. In other words, I just celebrated my birthday. And before you ask, I'm 53 years old..

What exactly does 53 years old mean? Well, the easy response is, "Joel, you're getting to be an old fart". But I'm wearing my cosmic hat today, and I'm liking the answer, "Joel, the Earth has orbited the Sun 53 times while you've been alive".

So the concept of the year is linked to astronomical events from an earthly perspective. But what if lived on the planet Mercury? Putting aside the fact that the planet is far too hot to sustain life, I'd be 222 years old!!! Whoa!

This can be explained by the fact that Mercury completes its "yearly" orbit around the Sun in just 88 days. And it has done that 222 times since August 7, 1957 (my birthday).

The following lists what my age would be on some of the other planets:
*Venus - 86 years
*Mars - 28 years
*Jupiter - 4 years
*Saturn - 1 year

Meanwhile, I'd be less than a year old on Uranus, Neptune and Pluto (Yes, I know Pluto isn't really considered a planet anymore, but I'm old school). These three planets haven't yet completed one full revolution around the Sun in my lifetime. In fact, I would have to wait almost two centuries for my next birthday on Pluto.

Graphic Perceptions

Graphs and charts can manipulate audience perception unethically by simple design variations. One can construct two different graphs based on identical data, and give an audience two very different messages.

Altering the range of data used for plotting charts is one way certain information can be either emphasized or de-emphasized. For example, certain trends can either be minimized or maximized on charts depending on how the data is plotted.

The following two bar charts use identical data, but the yearly decline in profits in the top one appears much more severe because of the smaller range of data along the axis.






A writer wanting to make declining profits seem worse might choose the top chart to manipulate unethically the perception of the audience.

THE FIRST ROAR

It was sometime during the summer of 1964; I don't remember the exact date. The hometown St. Louis Cardinals were in the middle of one o...
