Numberwareness

I've heard the speculation that a person's perspective of human kind's centeredness in the cosmos is directly proportional with one's understanding of math.

In other words, the less math a person understands, the more likely that person will think human kind is the apex and center of the Universe. However, the more math a person understands, the more that person will realize humanity is not even a blip when considering the grand scale of the Universe. Again, this is speculation.


Among the industrialized democracies, the United States lags behind in primary and secondary education. Math does not seem to be an exception. Also, I am no exception within this scenario and I long to better understand the important skill of understanding numbers. So, to do my part to educate myself and any who will listen, I will share some interesting comparisons that I've recently read. Perhaps this information could help us put ourselves and our cosmos into perspective-- a perspective largely described using numbers:

If you count at a rate of one number per second, you will need to count for practically 12 days before you reach one million.

At this same rate, you will need to count for 32 years to reach one billion (109).

To finally count to one trillion, you will need 32,000 years.

McDonald's claims to have served one hundred billion customers. If you took one hundred billion hamburgers and laid them end to end, the burger chain could circle the Earth 230 times! No wonder we've got obesity problems!

And you'd still have burgers left over to stack to the moon and back!

Those people at McDonald's are some rich Mo'Fo's.

If a person making $25,000 a year finds $0.25 on the side walk, then this is the same proportion to Bill Gates finding $25,000 laying around on the floor somewhere! In other words, $25,000 is merely twenty-five cents when compared to Bill Gates' wealth!
No wonder he can donate a billion dollars to AIDS research and not blink!
No wonder Gates only wants the world to use Windows!
(That Linux hater. Grrrrrr . . .)

If we placed a soccer ball in the middle of a soccer field to represent the Sun, we'd have to walk about ten paces from our soccer ball to represent the distance between the Sun and Mercury. About 20 paces away from Mercury would be the Earth-- Venus would fall somewhere in between. The moon would rest about an inch away from the Earth at this proportion. Amazingly, this is the furthest any human has ever physically ventured so far.


Jupiter would be found about 130 paces away from Earth in our "soccer field rendition" of the solar system. And Pluto would end up being half a mile away from the soccer ball which represents our Sun.

The nearest star? We'd have to fly 4000 miles away from our soccer ball to represent Proxima Centauri, the closet star to our planet besides our Sun.
Now try to consider the countless stars our telescopes can see.

If that doesn't put the universe into perspective, then take out the time to listen to what Carl Sagan has to say about our planet, the Pale Blue Dot:




A very humbling discourse indeed.

In light of all of this-- who are we to be cruel to one another? Who are we to think we are so much better than anyone who is different from us? Who are we to ever think that our minds are so high, that we don't have to turn skepticism towards ourselves?

Whether there be a god or not, each individual person is way too small to treat anyone else of lesser size.

To me, these humbling insights reveal the importance of "Numberwareness".

What's in a Second?

Well, year 2008 has passed and now 2009 is here.

But did you know that 2008 was just a little bit longer 2007?

And 2008 will probably be a little bit longer than 2009?

Just by one second.

So what?

Well ask "why", before saying "so what"?

The earth's spin is slowing down. The tides, the pull of the moon, solar winds -- all of these things influence the earth's rotation. Ever so gradually, earth is slowing down. So over the years to come, a second will be added. A leap second. Some years have them, others don't.

Given enough time into the future, A day on earth could last 30 hours rather than 24 hours.

What does that imply?

Everything isn't an absolute constant in our solar system. The planets are slowing down. Their speed and distances from each other are changing in slight ways. Everything seems constant, yet everything is changing all the time.

Even time is changing.

A second used to be 1/60 of a minute. Now, a second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom at rest at a temperature of 0 K (absolute zero)".

Say what?!

The fact that all these "constants" are constantly changing at minute (mi-nyut) levels decries the notion that our universe was set into place by absolutes. While this doesn't disprove god, this does tell me that what the bible says about creation is off base. I'll bet that all the creation stories from any given religion has our world etched into stone, so to speak.

I find all of this quite fascinating. I think I'll be chewing on this idea throughout the whole new year.

Truth Seekers

Ye shall know the truth and the truth shall make you free.

John 8:32


Many Christians say they believe in truth. People who fervently adhere to doctrine are often said to "love truth".

However, real truth often gets overlooked in the Christian world.

The abuse by ministers often gets swept under the rug. The victim is simply told that the abuser should be forgiven and the matter dropped . . . Many times, the issue is never addressed at all.

Why? Because, God's "truth" must prevail.

What is to be said about God's truth when it contradicts the reality you know?

What happens when you realize the earth has to be billions of years old? Much older than what they Bible claims.

What happens when you realize the stars and planets in the sky are millions of miles away and no heavenly throne is found in the sky?

What happens when you realize the stars cannot fall to the ground like figs?

What happens when you realize ministers from all faiths everywhere ignore and even hide abuse, though they claim the church is a place of safety and refuge?

What happens when you realize life is most probably forged through the process of evolution and that life is most probably scattered throughout this vast universe? Even if we never find other life, chances are good that within the billions of stars and planetary systems life similar to ours might exist.

What happens when your realize God's "word" is nothing more than the collective writings of mere men?

What happens?

You break free.

Jesus was right about one thing. The truth shall make you free.
