Nothing like taking a minute out of your busy life to look at a beautiful mountain landscape. You could almost imagine yourself right there hiking along and turning around to see this behind you.
The sun is hot on your skin, but there is a breeze that cools the sweat and you take in a deep breath of that fresh, clean air and you feel at peace.

We straightened the wall and added some plants. Now it looks much better.

This picture was taken when I was finishing my degree for Geology and Earth Science. I was out in the middle of no where in Wyoming with about 30 other students. Most of the time during our day the work was to walk around landscapes like this and take notes. It was quite pleasant most days.

|Interior of the Moon|
our Earth is certainly alive and one of the main reasons is because it still has an active core. The moon also still has an active core! The moon is not a cold chuck of rock floating around the earth. There is still an internal layer of the moon that generates heat due to gravitational forces.
How can scientists possibly know that?
Definitely....how can you really know anything?
Well since we can't really get a drill on the moon and put a thermometer into the core we can only use data we can measure and perceive. This means measuring the different deformations other gravitation fields have on a particular celestial body...the physics gets pretty intense pretty fast so suffice to say we can measure subtle changes in the shape of the moon as it rotates around the Earth.
This change scientists can measure is called a tide...the phenomenon on earth we generally refer to as oceanic tides. The gravitational forces between the sun and the moon are so powerful we can easy see the water displaced in our oceans.
As the moon deforms its inner layers transform some of that energy into heat. That heat maintains the soft layer within the moon. The softer the layer the easier it is for the moon to transfer energy into heat....see the cycle?

What does it mean to be a smarter consumer and why do you care?
|Reduce Reuse Recycle|
Pay attention to all the disposable things you buy and really try to limit their use. Yes it is much easier to just throw away paper plates and napkins...but watch as your garbage fills and fills. Lucky for you there is a system in place that will remove that garbage every week. Try to imagine the heaps that would accumulate if all you ever used were simple throw away things like plates and silverware.
Pay attention to single use and over packaged items. This one is a little more difficult because you will have to make some sacrifices. This sort of thing means not buying the pre-cut vegetables and fruit at the grocery store. Stop paying for convenience and start paying attention to the amount of packaging you throw away. It really is not hard to cut your own vegetables or fruit.
Here is a list of a bunch of stuff you can live without...I promise:
Paper Billing: I don't know about you but I used to get 20 envelopes a month for bills that I already have automatically scheduled to pay. Take 5 minutes out of your super busy life and sign up for electronic billing. Some companies even offer rewards for signing up!
|Land Fill Full of Disposables|
Tin Foil: I know its easy just to grab some tin foil...wrap up that pizza and go, but that is an obvious waste we can live without. Invest in some good glass/plastic containers instead.
Non-Reusable Batteries: obviously you use them and throw them away...unfortunately these can be considered hazardous waste - try and use rechargeable ones instead.
Bottled water - bottled anything: If you are not going to recycle the plastic water bottle because it is a pain...then please please please use your own water bottle and fill up at drinking fountains.
Cutting out a few of these things will make a difference.
Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials
exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.
The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The first photovoltaic module was built by Bell Laboratories in 1954. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline. During the energy crisis in the 1970s, photovoltaic technology gained recognition as a source of power for non-space applications.
Thanks to NASA for putting it so well...you can find the rest if you would like to follow the link.
