Two Things At Once






Howdy folks. Sorry for the long break, but I did warn you. I have gotten past the most intense time of the year, job-wise, with sanity and babies generally intact. Woohoo! Today I bring you two babies in a play gym. This will be followed by a rant. Feel free to skip it, but then you might not learn something today...

The play gym is a Baby Einstein product given to us by the fine Deacon household. Let us hear a shout out. The Baby Einstein business plan is to take shakey child development theory, extrapolate it far beyond even that weak scientific foundation, market a product based on this wild extrapolation as a tool that will make your child smarter and more well-adjusted, and then charge too much for it. The real Baby Einstein is the CEO who every night rolls around in a bed covered in money that has been dredged directly from the dreams of well meaning parents.

As of 2001 the company was purchased by Disney, making its evil nature official. That all being said, I am sure I will continue to buy their products, because hey, I want a genius baby as much as the next guy.


The Gym, as you can see is basically a colorful, padded mat with criss-crossing bars that go overhead. The bars come with handy places from which one can hang roughly one zillion things, reducing the baby to complete sensory overload. These items include rattles, mirrors, animal pictures with text (both photos and cartoon representations), squeaking birds, and the centerpiece of the whole aparatus: A star that plays music and lights up the tips of its star in rhythm with the music. I can't quite place the tune, but it is not a lullaby. Imagine high energy gypsy music. The philosphy is clearly the more stimulus the smarter your baby will be. Next I am going to get one of those freak-out chairs from Clockwork Orange (or LOST) and pin their eyes open.

In practice it is a nice alternative to the Mobile for something to engage their attention and reduce parental strain. As they get older the two of them will probaby interact with it more and it will go from Baby TV (passive) to full-fledged interactive toy (Baby XBOX). Also note they hold hands in most of these pictures. That is some cute-ass stuff, right there.





The weak connecting thread of this blog is the question of whether the typical person can hold two ideas in their head at once. Up top is a toy based largely on information overload. Does that prepare us for the world, or simply begin the bombardment at a younger age. A common symptom of info-overload is the inability to absorb useful information at all. Like the explorer who tries to hold too many items (lantern, mail, a grue) , he may just end up dropping them all.

Case in point and my present pet peeve: Global Warming and Ozone Depletion. Despite what appears to be the majority public opinion, these are not the same issue. There are TWO significant things human activity is doing to our atmosphere. Sadly, the average American seems unable to keep the two ideas in their head at the same time. Partly this is because they never really understand the problem, and partly because of info-overload. The details (like there are two separate atmosphere problems) get lost along the way.



Quick Primer:

The Ozone Layer is a section of triply connected oxygen (normal oxygen is doubly bonded) that lies roughly at the top of our atmosphere. It is valuable because it absorbs
a large percentage of the harmful ultraviolet rays that hit the Earth from the Sun. Without the ozone you would sunburn in a fraction of the time you presently do. Certain chemicals we make, most famously chlorofluorocarbons (CFCs), float up to the top of the atmosphere and destroy ozone. One rascally CFC molecule can break apart a huge number of ozone molecules, making them doubly pernicious. Huge holes in the ozone have opened up over the poles (north and south), which scientists believe are related to this release of CFCs. CFCs are being phased out in the United States, but are still wildly used around the world as a cheap way to run air conditioners and produce foam products (like a seat cushion). At one time they were used as propellant in aerosol cans, which is the image a lot of people connect to it... and to global warming for some perverse reason.

Global Warming is the steady increase in the average temperature around the world because more and more greenhouse gases are being sent into the atmosphere. This occurs for basically for the same reason your car warms up hotter than the air around it on a sunny day. Light comes in through the window (atmosphere) gets absorbed by the seat (ground) and then is re-emitted as infrared heat which can't escape the window (atmosphere). Carbon dioxide is called a greenhouse gas because it does not let the infrared heat out, warming the planet. There are many ways to make CO2, but the easiest is to burn something. Like oil. Or natural gas. Or trees.
Burning trees is a double whammy, as it also destroys plants that take CO2 out of the air. By the way, freakishly cold winter days are not evidence against global warming. Increases in temperature cause increases in volatility. That is a fancy term saying things will go up and down more. So while the average day gets hotter, you will actual have more freakish days -- both super hot and super cold.

There is a bit of confusion because CFCs are also greenhouse gases (they absorb heat), but they make up a tiny percentage of the problem compared to CO2.

What has set me off is an article in the New York Times. The original article title was: "As Asia Keeps Cool, Scientists Worry About Global Warming". It was about the huge rise in the use of air conditioning in India and China, which all use CFCs because they are so much cheaper. So the clever title was misleading. In fact, if you read the article is makes no mention of global warming at all. At some point someone besides me must have thrown a brick at the Science Editors head, because now the title says they "...Worry About The Ozone Layer". Not as clever, but not as misleading. And this was the N.Y. Times. Supposedly some of the best print journalists around.

Now before anyone has a conniption, yes, air conditioning tends to be one of the largest power hogs around. Power takes electricity. Electricity is more often than not generated by burning things. So it is an issue for Global Warming as well, but the article was about the ozone issue. A DIFFERENT issue.

But modern mankind can't seem to keep two ideas in its head.

We had exactly the same baby gym for Kynan. When we first put him on it, he lasted maybe 3 minutes before crying. The lighted star and hyped up muzak really upset him. As he got older though, he really dug being able to swat at the hanging toys.

Being able to hold two thoughts at once is a skill that comes after being able to hold one thought for a lengthy period of time and tackle it from a couple of angles. I think, as a country, we can barely do the latter. Witness the "Britney in rehab! No! Anna Nicole dead!" stories that dominate a lot of the media. These require no depth of understanding, and no thinking beyond a cursory minute or two.

Two thoughts? Heck with all the sleep deprivation I can baerly hold on to one thought, but if it makes you feel better I did know the difference between global warming and the depletion of the ozone layer.

The delpetion of the ozone is why fair skinned people like me who want to get less skin cancer than we otherwise would must wear gobs of sunscreen and expensive UV blocking clothing (both of which are probably made using processes that increase global warming.)

Global warming is why all those rich people in Malibu will get to watch their beach houses fall into the ocean in the next few decades when the sea levels rise.

And I'm wondering... is the baby gym meant to make them smarter or kick start a life long adiction to expensive but ultimately useless exercise equipment like the ab flexer, stair master and the treadmill. They do call it a baby GYM. Perhaps next Disney could sell a line of diet formula and baby yoga products.

Also, a totaly non related and non earth centric question came up over lunch, but we knew you'd have the answer. What is the current estimated age of the universe?

The age of the universe is relatively uncertain, with several of the major numbers still mildly controversial, particularly the one that says the universe is expanding.

However is we assume the most popular present cosmology:

Hubble Constant= 71 km/s per Mpc
Omega Lambda= 0.73
Omega Matter= 0.27

Then it has been
13.666 Gyr since the Big Bang.

Any of those numbers can be explained further if you need your mind blown. Or be bored to sleep. Kind of depends on your disposition.

Sorry, Gyr is short for billion years. It has been 13.666 billion years since the big bang.

By billion I mean one thousand million years. This shouldn't confuse any scientists, but a Brit off the street might think I meant a million million, which nowadays most people call a trillion. As in, "The U.S
owes China trillions of dollars"

Ahhh... And now I am having flashbacks to Carl Sagan... "Billions and Billions of years ago.."

Thank you so much for offsetting what has become a habit of brain melting activity, by providing me a stimulating read at my workplace!

Crap. I mis-typed in my universe age commment.
So a quick Cosmology 101

The contraversal thing about the universe is whether it is ACCELERATING. Not whether it is expanding. That is about as established as you can get.

So all the galaxies in the universe are definitely getting farther and farther away. How fast they are moving away is the Hubble constant (71 km/s per Mpc). It is this motion that allowed Hubble to originally deduce everything had to be all together at one point, i.e. back when the Big Bang happened.

In the past decade astronomers have measured that the expansion is not slowing down (as originally believed) but accelerating. The reason for this acceleration is completely unknown, although there are all sorts of wacky theories.

Omega Matter is the density of physical stuff in the universe, scaled so that 1.0 is exactly the amount needed to cause the universe to slow down and re-collapse.

Omega Lambda is density of the energy that is causing the universe to expand, often referred to as vacuum energy, but we really have no clue.

With Omega Lambda significantly larger than Omega Matter the universe expands forever.

So there you go. You are Universe experts.
